Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a non-slip device that can be attached to and detached from a tire of an automobile for snowy roads and frozen roads.

"Prior art" To prevent slipping on snowy roads or frozen roads with conventional automobile tires, hard spikes are embedded in the tread of the tire so that the tire can be prevented from slipping, and a part of it is exposed from the tread. The so-called spiked tire and the tread made of special rubber of soft compound that deforms following the shape of the road surface, and the groove shape (tire pattern) provided in the tread of the tire makes the studless tire non-slip There is.

Spike tires have some anti-slip performance even on snowy roads, and have anti-slip performance on freezing roads, but on dry roads spikes scrape the road surface, resulting in environmental loss for health and economic loss for road repair. And the noise due to the tire is also large. Further, the studless tire has a sufficient anti-slip effect on a snowy road, but does not have a sufficient anti-slip effect on a frozen road, and the noise caused by the tire is slightly higher than that of a normal tire for dry roads.

As described above, such spiked tires and studless tires are not suitable for dry roads, and are not suitable for use on dry roads. Therefore, a large number of slip stoppers that can be attached to and detached from normal tires for dry roads that can be used only on snowy roads and frozen roads have been proposed and used in large numbers. Of these removable slip stoppers, the ones that are often used are those made of steel chains, and generally those that are in the form of a ladder in the unfolded state are often used.

The above-mentioned steel chain anti-slip device exhibits excellent anti-slip performance through snow-covered roads and frozen roads. However,
Steel chain anti-skid devices are subject to vibration and noise on dry roads and must be removed after snow or icy roads. The steel chain is easy to put on and take off. Therefore, an anti-slip device that is an improved steel chain that is easy to put on and take off, and has relatively little vibration and noise on a dry road has been proposed. Nevertheless, it is expensive.

"Issues to be solved by the invention" Front-wheel drive front-wheel steering automobiles In so-called FF vehicles, anti-slip devices are attached to the front wheels of the drive wheels. Also, in a so-called part-time four-wheel drive vehicle in which two-wheel drive and four-wheel drive can be selectively performed, two wheels that are always driving wheels are run with a non-slip device mounted, and four-wheel drive is always performed. In a driving vehicle, a slip stopper is attached to the front wheel or the rear wheel having the larger torque distribution.

For example, in a front-wheel drive vehicle, if steel chain slip stoppers are attached to the front two wheels and braking is applied while the vehicle is running, the rear wheels may skid on the icy road, causing the vehicle body to become slanted, or turning sideways in extreme cases. It may happen. Such behavior is relatively well known to the driver, and is prevented by applying a braking force gently. However, it is an unexpected occurrence that the braking force must be applied so that the two front wheels generate a sufficient braking force, and even if the vehicle can be stopped, the posture may change significantly, which is a safety issue. It was In rear-wheel drive vehicles, when braking is applied to the rear two wheels, the posture is rarely changed when the brake is operated within the range where the braking force works (the range where slippage does not occur), but the steering angle does not change even during slow speed running. If it changes drastically, the front wheels will be out of control and the car will tilt.

In the case of a four-wheel drive vehicle with four-wheel drive, the limit until the above behavior occurs is large, but once the two wheels on the side without the slip stopper slip, the same state as in the two-wheel drive is obtained. Will end up.

The above points can be solved by mounting anti-skid on all four wheels, but new problems arise. That is, (1) attaching and detaching the slip stoppers to all four wheels requires almost twice as much labor and time as compared with attaching and detaching to the two wheels. (2) Noise and vibration become significant, and the vehicle travels in a range where noise and vibration do not occur, so the traveling speed is significantly limited. (3) There are drawbacks such as the cost of the slip stopper being high.

In order to solve the above problems, this device is easy to install and is noisy,
It is an object of the present invention to provide a non-slip device that does not easily generate vibration.

"Means for Solving the Problem" The first invention of the present invention is to provide a plurality of adapters at intervals on a strip, and to join the strips at both ends of the strip with the adapter in a ring shape. Is provided with a detachable end coupling means, and the strip with adapter has a length that can be accommodated in a circumferential longitudinal groove provided on a tire tread in a state where both ends are coupled by the end coupling means. However, the adapter has a protrusion part of which protrudes to the outside from the tread of the tire when the tire anti-skid device is mounted, and the adapter has a tire anti-skid device in which at least the protrusion part is configured to be hard.
