To produce rubber spikes will be the same owned by the Kontinental c 2007 the Finnish company Tikka Spikes that makes a classic.

Velcro or spikes is one of those perpetual disputes, even though the ruble we vote is clear: in Russia one of the friction tires have four studded lover. Their share may grow, when in August-September 2019 the market will go Continental IceContact 3 with unusual spikes. In conversation they are often referred to as rubber, although they just obrezinena (shell hardness reminiscent of the protector material), and the grip meets the usual carbide insert with aluminum support flange.

The flight, size and weight of the spike correspond to common values of the regulated. Even the number of inserts is not particularly going to change ― a little less than two hundred on the wheel. However, the claimed improvement of coupling properties on ice by seven percent. In this case the wear of the coating should be reduced by 20% ― that is, theoretically, without violating the homologation requirements, the number of spines could be to increase accordingly.

It is not “the three” and the pilot IceContact2 c index RS is equipped with a rubber spike. These tires are a limited edition sent to dealers. On a new tire insert FlexStud visually indistinguishable from conventional: they are bathed in the same gray-beige retainer structure.

However, talking about a possible tightening of European regulations on the wear of the coating with the studded tires. In the industry a very bad way of looking at hyperspace Michelin X-Ice North 4, each of which has 250 or more steel inserts. Apparently, the Continental margin, or just really believe in their new technology. On paper, everything is really beautiful. The soft body of the spike allows hard core deeper bite into the ice (spike’s working angle — see illustration below) and not to “cut” waste asphalt. And ― very important ― rubber walls work like damper noise and vibration. Checkmate, fans of stickers?

Under the action of lateral and longitudinal forces of the tongue tends to lie down. Aluminum body prevents him to keep contact with the ice, and on asphalt waste is harmful to themselves and to the coating. Elastic case these problems like deprived: grip ice is growing at seven percent and wear reduced by 20%.

The practical part of the seminar devoted to the new Contico, at the site of Jaguar Land Rover Experience serious organized strangely. Let’s start with the fact that commercial bus current series IceContact2 and pilot IceContact2 RS of the same dimension 235/45 R18, but with spikes FlexStud, mounted on cars of different classes. In the first case it is the Jaguar XE, the second is more expensive XF. In addition, we are not allowed behind the wheel. It is proposed to evaluate the difference of the acoustic and vibration comfort from the passenger seat. What can I say?

It was my first time on the range Jaguar Land Rover Experience. Nice complex with good potential, but was surprised by one of the instructors who tried to teach me how to brake with your left foot.

In the Parking lot and by rotating the wheel to place the latest FlexStud also postrelivat metal on the asphalt, and 20-30 km/h note the lower level of the resonant rumble and high-frequency small itching on the floor. But it is difficult to objectively judge the extent to which it is a merit of the tires and in a car of higher class. Abstracting as much as possible from aggregatelevel and based on experience with tires, I can assume that the acoustic properties of the novelty is located approximately in the middle between the classic “shipovymi” and the latest friction tires VikingContact7, which also was able to ride.

The main large-scale new Conti ― friction “Scandinavian” VikingContact7. The transition to the drain symmetrical pattern explain the increase in winter temperatures. Canola oil allows the rubber compound to allow for reliable lateral grip to soften in the heat (ie, at a temperature around 0 ºC).

This, of course, not a test. But it will be interesting to try FlexStud on snow and ice. Not only fresh, but also with the mileage, because the tire manufacturers promise that rubber spike wear out more evenly, almost completely retaining its properties of the engagement as the operation.

Do not forget about primocanale. In the course of the production tire is removed from the mold a bit “underexposed”, mounted, inflated, and then the automation inserts the spikes, covered with a special compound. Then the bus devulcanized in an autoclave where the structure connects the tongue with rubber. Let not tightly, but in order to pull it requires four times more effort than the usual studding.

Brand photographs illustrating the wear of the stud. Top ― new rubber FlexStud, bottom ― serial spike tires IceContact2, stronger losing their properties.

This year, the Continental plant in Kaluga was five years old. Half of its production is exported. Latest IceContact3 will be developed simultaneously with the German plant in Korbach ― only these two factories can do studded Conti.

By the way, technology primocanale patented Continental “length and breadth”, so is eight years and remains unique on the market ― the competitors have no right to reproduce it. All the research arm of the company, including not only tire manufacturers (in the amount of 30 thousand scientists and engineers!), per year gets about a thousand patents. On this basis, we can assume that the rubber spike is unlikely in the next few years will learn something.

Behind the scenes

The second topic of the seminar was an attempt to once again compare the behavior of studded and non-studded tires. But winter in Moscow is not in a hurry, forcing us to work exclusively on wet pavement. Weird, but in a predefined weather conditions for the latest season 2018-2019 friction ContiVikingContact7 on road handling seems preferable to spikes, no seeds IceContact2. Slide is not as deep, and breakdowns ― a little smoother. Journalistic competitions I won and those and others. However, we must remember that the main loss nesipbek falls on snow and especially ice in the temperature range from zero to -15 ºC.

Lifting, filling and not only was the Soviet special vehicles for airports

In 1950-ies in the inexhaustible sea of the Soviet special vehicles appeared brand new class unusual and practically unknown airfield of machines for service at major airports of the country air passengers and the new turbojet aircraft. These included a unique and sophisticated means of transport from the self-propelled stairs, Luggage loaders, lifts and autolifts to cleaners of toilets and all kinds of tankers. Many of them no longer exist.

Tagelou airfield vehicles we will leave for another article, but for now imagine how many years ago this spacious bus took us to the plane. Lifting it was hard to imagine that beneath your feet the car. More precisely, the electric car special design. In ancient times it was common in the USSR, self-propelled passenger stairs SPT-104 and SPT-114 for maintenance of Airliners of the Tu-104 and Tu-114 with the landing area at a height of 4.1 and 5.4 meters respectively. They were equipped with electrically powered rear wheels and all units from the accumulators and four retractable supports to ensure the sustainability of the whole Assembly. The driver was placed under the ladder and ran regular steering wheel.

Such electrotherapy differed quiet, easy to use, nice streamlined shape. Short runs, low speed (7.5 km/h), smooth surface and the proximity of electrical outlets allowed to use them in many Soviet airports and in neighbouring countries.

Several other types of self-propelled ladders were mounted on production cars. Of these, the most widely used high-speed sliding SPT-20A and SPT-21 on the short wheelbase versions of chassis UAZ-451Д and UAZ-452Д respectively.

They are usually served in small airports, where they could move out smooth coating and to serve aircraft with a level entry door up to four meters. The ladder is supplied with two tents with 13 lighting shades. To ensure that it is accurate summing up to the plane in the roof of the cab there was a viewing window. The mass of avtorov was 2.6 tons. Maximum movement speed: 40 km/h.

So we climbed into the plane and sitting comfortably at the window. Through it can be seen as a long line of baggage carts carry our bags. But how to raise this a considerable load on multimeter height in the cargo compartment of the aircraft? Then came to the aid of the Luggage autotransporter at-2 and at-4M on the chassis of GAZ-69 with double open or closed cabins and length of the arrows in eight or ten meters.

They provided a conveyor drive drums, the folding of the extreme sections, raising and lowering the middle part and work the outriggers.

Volvo has launched initiatives for security

Volvo wants to start a discussion about whether the automaker by applying constraints to change the behavior of drivers. As mark is ready to take “active responsibility” for the security, she believes such intervention is their right or even duty.

The Swedish brand is celebrating the 60th anniversary of three-point seat belt — “probably the most important invention in the history of automotive safety.” This device, which became the industry standard, saved, estimated to Volvo, more than a million lives. What’s next? The company has already decided in 2020 to limit the maximum speed of their cars at around 180 km/h Now put forward three initiatives: the E. V. A. project (Equal for all vehicles), key Care Key and the camera that monitors the driver’s behaviour. It’s all part of the strategy Vision 2020, under which the dead and seriously injured in a new Volvo car should not be.

Project E. V. A. aims to provide the same level of safety in the car for everyone, but the emphasis is on the protection of women. After all, they are, according to Volvo, are at greater risk of an accident due to anatomical features. For example, the cervical spine in men stronger.

Initiative E. V. A., the company are willing to share their research in the security sphere, ongoing since the 1950s. More than a hundred articles based on a thorough analysis of tens of thousands of real-world accidents. In particular, the digital library offers access to content on protection against whiplash and injuries of the lumbar spine.

Key Care Key will go “in the” all Volvo cars from 2021. It allows owners to set speed limit for yourself, family members and friends who use one machine. The idea is that Care Key is particularly useful for teenagers, just got a license.

In early 2020-ies Volvo promises to provide the next generation platform SPA, which is called the SPA2. In the basic equipment of all models, built on a “truck”, will include a system of cameras and other sensors that continuously monitors the state of the driver. The main task — the fight against drunk driving (cause 30% of accidents) and distraction.

The prototype two cameras mounted at the upper corners of the windshield, but the exact number of “eyes” and their location in the cabin will be released at a later date.

If the “obviously drunk” or distracted the driver does not react to the warning signals a long time looking at the road, sitting with eyes closed, acting too slowly or, on the contrary, extremely rebuilt — the car gets a right to intervene. It limits the speed alerts support through the service Volvo on Call, and in an extreme case, brakes to a full stop and finds a safe Parking. Except that the police is not, though…

However, along with the carrot there is the carrot in the form of “financial benefits”: good driver not only avoid trouble, but will be much less to pay for insurance. Soon Volvo will announce the first of several agreements with the insurance companies in Sweden. Specific terms of the transaction will depend on conditions in a particular market.

Simple solution: as every year to go to the new crossover Nissan

Most new car buyers still operating in the traditional way, buying a car on credit and paying it in three years, sell a car, to make a new one. However, there are those who have already tasted the benefits of leasing programs, thanks to which owning a car is not burdened with either service or insurance or taxes or other related costs, and the car can be replaced with new at least every year. It is a program jointly developed Major and Nissan. How it works, and what is the benefit?

Affiliate material

Te who are familiar with the leasing scheme, it is easy to guess in the “Simple solution” is one of such proposals. A distinctive feature of the service from Major – regular updates to vehicle: the contract for the rental of the car is signed for one year, after which the customer can either buy a car on favorable terms, or that is more logical for the leasing scheme, to exchange it for a new one.

What is the benefit?

To understand the benefits of the proposal, it is sufficient to compare it with the standard purchase of a car on credit. As an example, take the “average” variant: Nissan Qashqai for 1.6 million rubles. The first condition for the acquisition of the loan is the initial fee in the amount of 450 thousand rubles. Of course, the loan is accompanied by a mandatory insurance of the collateral: for CTP and hull will have to pay 50 thousand and 30 thousand will cost life insurance that is also required by most banks. Things like floor mats and a set of the motorist at the time of purchase against the General background seem unnoticed, however, and they are 5-6 thousand to spend.

So, paying a lump sum of about 540 thousand, the buyer leaves the showroom. Considering the average annual mileage in the first year of owning the car he will need to pass one to buy a set of winter tires and twice to set. Taking into account the cost THAT 1 in 12 thousand and a decent winter tire as well as tire service and seasonal storage of tires routine maintenance will take another 60. Throw in 5 thousand roubles of the transport tax for the 144-strong car – and get almost the full cost of owning a car, not including optional “special stages” such as replacing the music, seat covers and other.

Well, the third item of expenditure when buying a car on credit is actually a loan. In our conditions, subject to a monthly payment of 37 thousand for the first year will have to pay 444 thousand rubles. Adding to this the amount of the initial contribution and the cost of insurance and owning a car in the first year, we get about 1.1 million – and ahead of a few years of the loan, maintenance of compulsory insurance and so on.

Against this background, the program “Simple solution” fully justifies its name. The fact is that, choosing a car, simply arrive at the dealership with a package of documents, to make an advance payment equal to one monthly – and go on a new car. Do not need to insure himself or the car at your expense, no need to pay for registration, no need to pay extra for floor mats and even THEN: everything is included in the monthly payment. Given that the leasing scheme the actual owner is the lessor in the face of a major Pro, vehicle tax, insurance and registration pays for it. Thus, to go from the salon on the new Nissan Qashqai, in this case you will need to 33.5 thousand rubles – and no unaccounted for additional costs.

The second advantage of leasing – no need to pay for the service and maintenance of the car: all of this is also taken into account in the monthly payment. Getting to use the machine on the program “Simple solution”, the client receives a “complete” winter tires, free tire and seasonal storage of wheels, and-1. Simply put, we can only fill the car and drive it – all the rest is already taken care of in advance.
