Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automobile equipped with a slip prevention device for snow-covered and icy roads in winter, and in particular, the present invention relates to a vehicle equipped with a slip prevention device for snow-covered and icy roads in winter, and in particular to a vehicle equipped with a slip prevention device for snow-covered and icy roads in the winter. The present invention relates to a moving vehicle equipped with an anti-slip device that can extremely easily adapt to road conditions without requiring much time.

[Prior Art] Conventionally, methods for vehicles to drive on snowy and icy roads without slipping include installing spiked tires with studs on the tread surface, and methods for driving on snow and ice without using studs. There are three methods: installing studless tires with compatible treads, and installing tire chains on the tires.

Among these, spiked tires have excellent grip on road surfaces, but dust pollution caused by use on road surfaces other than snowy and icy roads has become a social issue. Further, since studless tires do not have studs, there is no risk of generating dust pollution, but since studless tires do not have studs, spiked tires do not have grip performance on any road surface.

Therefore, it is common practice to wrap tire chains around tires only when it is snowing. Furthermore, the grip performance on snowy and icy road surfaces is greatly improved by wrapping tire chains around the tires.

[Problem to be solved by the invention] However, when a car equipped with tire chains drives on a general road surface without ice or snow, it goes without saying that the required speed cannot be obtained, and vibrations occur due to the tire chains hitting the hard road surface. The amount of noise is indescribable, and it is therefore necessary to remove the tire chains from the tires on regular roads.

In particular, the chain regulation during snowy conditions on expressways requires tire chains to be attached and detached depending on the road surface conditions, so when snow-covered roads and regular roads alternate, tire chains should be attached and detached. In addition to requiring a great deal of effort and time, they also had to endure the bitter cold outside the vehicle.

Therefore, the present invention has been developed to enable automobiles to cope with snowy and icy roads in a short time by extremely easy operation, without having to perform tire chain skinning work that requires a great deal of labor and time while enduring the severe cold as described above. It is an object of the present invention to provide an automobile with an anti-slip device that can prevent slips and can be used on general road surfaces by canceling the anti-slip function in a short time with extremely easy operation.

[Means for Solving the Problems] In order to achieve the above-mentioned object, an automobile with an anti-slip device of the present invention includes a first telescopic member that is vertically expandable and contractible, and one end of which is fixed to the suspension mechanism of the automobile. A second member is attached to the other end and is movable toward and away from the road surface of the vehicle, and one end is fixed to the axle housing of the drive wheel of the vehicle and is extendable and retractable in the left and right direction.
The anti-slip wheel is attached to the other end of the telescopic member and is movable toward and away from the tread surface behind the driving wheels of the vehicle traveling on snowy or icy roads via an intermediate roller. It is something to do.

[Function] Since the present invention has the above-described configuration, when driving on a snowy road surface or an icy road surface, the first telescopic member is driven to bring the anti-slip wheel into contact with each of the road surfaces, and
By driving the second telescoping member to bring the anti-slip wheel into contact with the driving wheel of the vehicle via the intermediate roller, even if the driving wheel slips on each of the road surfaces, the anti-slip wheel can securely grip the road surface. This allows the car to drive safely without slipping.

Additionally, when the road surface changes from a snow-covered or icy road surface to a regular road surface, the anti-slip wheels can be moved from the driving wheels and the road surface by driving the telescopic member in the opposite direction to when the anti-slip device is used. This allows the anti-slip device of the present invention to be stored.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

The outer circumferential surface of the tire of the intermediate roller 7.7 is provided with anti-slip grooves, and the outer circumferential surface of the anti-slip wheel 8 is made of iron,
It is made of stainless steel or the like and is wrapped with an anti-slip member such as a chain 9 that improves grip characteristics on snowy and icy roads.

The intermediate roller 7 is indispensable in order to make the rotating direction of the drive wheel 4 and the anti-slip wheel 8 the same, and the intermediate roller 7 is essential for making the rotating direction of the driving wheel 4 and the anti-slip wheel 8 the same, and also absorbs vibrations caused by the rotation of the anti-slip wheel 8 around which the chain 9 is wound. Since the vibration is not transmitted directly to the motor vehicle, it also exhibits the effect of reducing vibrations transmitted to the automobile.

The second telescopic member 2a and the second telescopic member 2b are connected to a hydraulic pipe (not shown) from the vehicle body by operating a controller (not shown) provided in the driver's seat of the vehicle.
When using the anti-slip wheel 8, the first telescopic member 2 is driven hydraulically via the
The second telescoping member 2b contracts as the part a expands, and when the anti-slip ring 8 is stored, the second telescoping member 2b contracts as shown in FIG. 3(b).
As shown in the figure, the first telescopic member 2a contracts and the second telescopic member 2b expands.

Therefore, when the anti-slip wheel 8 is retracted, the anti-slip wheel 8, the intermediate roller 7.7, etc. are hidden inside the vehicle body, so that they are hardly noticeable from outside the vehicle.

In this embodiment, the chain 9 is wrapped around the tire outer circumference of the anti-slip wheel 8, but in other embodiments of the present invention, although not particularly shown, spikes or the like are wrapped around the tire outer circumferential surface of the anti-slip wheel 8. A slip prevention process may be applied by embedding a plurality of chain members of the chain 9.
It is possible to obtain grip characteristics such as between the road and the road.

Further, in this embodiment, the number of intermediate rollers is two, but the number is not limited to two as long as the rotational force of the drive wheel 4 can be reliably transmitted to the anti-slip wheel 8. ,
The number may be one or three or more.

Effects of the Invention As detailed above, according to the vehicle with the anti-slip device of the present invention, when driving on a snowy or icy road surface in winter, the first telescopic member and the second telescopic member are driven. hand,
By bringing the anti-slip wheels into contact with the drive wheels via intermediate rollers and with each of the road surfaces, it is extremely easy to attach and detach tire chains without having to endure the severe cold and take a lot of effort and time. With simple operations, it is possible to prevent the vehicle from slipping on snowy or icy roads in a short time, and with extremely easy operations, the slip-slip prevention device can be released in a short time to stabilize ordinary road surfaces. It is something that can be driven.

In addition, by driving the first telescopic member and the second telescopic member by 4 degrees and storing the anti-slip wheel inside the vehicle body, it is possible to make the anti-slip device less noticeable from outside the vehicle. It does not spoil the beauty. Furthermore,
The anti-slip device of the present invention may be installed on a car only in the winter when the device is used and not removed outside of the winter when the device is not used, but may be left on the car at all times, thereby preventing slippage. The device only needs to be installed in a vehicle once, and the labor and time required to achieve the anti-slip function are greatly reduced.
