Description

  It is a device for vehicles such as trucks and buses equipped with double tires, and when the vehicle runs on a road surface where snow and freezing are mixed, without stopping the vehicle by remote control from the driver's seat, etc. The present invention relates to an anti-skid metal fitting attaching / detaching device for an automobile that can attach or remove anti-skid metal to / from a drive wheel according to the road surface condition.

  Conventionally, when an automobile travels on a frozen road or the like, as an anti-slip measure for the tire, each time the automobile is stopped, an anti-slip device such as a chain is attached to or detached from the tire, or a spikeless tire during the winter season There was a method of wearing etc.

  However, it is very annoying and dangerous to stop the car on the shoulder and attach the chain etc. to the tire each time. Spikeless tires are more resistant to slippage on frozen roads than spiked tires. It is said that the ability is inferior, pollution due to the use of a large amount of snow melting agent is also a problem, it does not cause dust and other pollution, and it has a high anti-slip ability like a spike tire, that is, depending on the road surface condition There has been a long-awaited tire anti-slip device that can easily put in and out anti-skid tools such as spikes while driving.

  Therefore, many proposals have been made to deal with such problems. (Japanese Patent Application No. 3-72264, Japanese Patent Application No. 4-39140, Japanese Patent Application No. 2002-134622, etc.).

  However, for example, in the proposal of Japanese Utility Model Application No. 3-72264, there are many holes through which spikes pass through the ground contact surface portion of the tire body, and there is a possibility that earth and sand etc. enter the inside of the tire and damage the tube. It was a difficult proposal.

  The present inventor has also proposed an anti-slip attachment / detachment mechanism for automobiles in order to deal with such problems. (Japanese Patent Application No. 7-284531).

  However, the above-mentioned proposal is unsatisfactory in terms of safety because the device protrudes greatly from the side of the tire, and the device may be damaged due to contact with a curbstone or the like.

Problems to be solved by the invention

The present invention was created in response to the above problems, and the purpose of the present invention is as follows.
(1) Spikes and other operations can be performed from the driver's seat regardless of whether the vehicle is running or stopped.
(2) Do not process tires that may impair their function.
(3) The non-slip device should not protrude from the side of the tire.

  An object of the present invention is to provide an anti-slip device that solves the above problems.

Means for solving the problem

  As a means for solving the above-mentioned problems, the present invention attaches a support shaft coaxially with the axle to the end of the automobile axle that passes through the wheel of the rear tire, and a reduction gear coaxially with the support shaft. The output shaft of the reduction gear is coaxially and rotatably attached to the support shaft, and the casing of the reduction gear is covered with a gap from the side surface of the tire to the tread surface. The first slip is provided by connecting n pieces of anti-slip fittings, which are spiked, generally L-shaped and rich in elasticity, consisting of first anti-skid fittings to N-th anti-skid fittings. The stopper is fixed to the reduction gear casing, the N-th anti-slip bracket is fixed to the output shaft of the reduction gear, and a strong string is provided between the first anti-slip bracket and the N-th anti-slip bracket. When attaching the anti-slip fittings to the tires The retainer attached to the vehicle body and the motor of the speed reducer are driven to release the anti-slip fitting from the retainer, and the first anti-slip fitting to the N-th anti-skid fitting are centered on the tire. The fan is deployed and arranged to open on the outer periphery, and the spike is pressed against the road surface by the load of the car to produce the same anti-slip effect as the spike tire, and when the anti-slip fitting is removed from the tire, the holding machine and the deceleration Reversing the motor of the machine, setting the holder of the holder to the holding position, and reversing the output shaft of the speed reducer to close the first anti-slip bracket to the N-th anti-slip bracket so as to close the fan; and By holding the closed anti-skid fittings with the support fittings and running, the anti-skid effect of a spiked tire is exhibited on frozen roads, and the non-snowy roads can run without damaging the road surface.

Effect of the invention

  Since the present invention can attach and detach the anti-skid fitting without stopping the automobile from the driver's seat, which has been very troublesome in the prior art, it has a great effect in preventing slip accidents on a frozen road and protecting the road surface. In addition to giving up, the time required for attaching and detaching the chain etc. becomes unnecessary.
