Abstract

The invention discloses an anti-skid device for an automobile, which comprises an automobile wheel shaft, a telescopic device and an annular component, wherein the height of the annular component is equal to that of an automobile wheel; the annular component is fixed at the peripheral part of the automobile wheel; a plurality of punching holes are formed in the annular component at intervals; the telescopic device is formed by telescopic rods and hydraulic cylinders; the telescopic rods are arranged inside the hydraulic cylinders; the hydraulic cylinders are arranged on the side wall of the automobile wheel taking the automobile wheel shaft as the center; an arc-shaped plate is connected to the top end of each telescopic rod; anti-skid nails regularly arrayed are arranged on each arc-shaped plate, correspond to the punching holes in the annular component, and can stretch out and retract under the adjustment of the hydraulic cylinders. According to the invention, the anti-skid nails can firmly grasp the ground through the annular component, and the friction between the anti-skid nails and the ground is increased; besides, in the unnecessary situation, the anti-skid nails can retract and the normal driving of the automobile wheel is not influenced.

[0011] The present invention will be further described in detail with reference to the drawings of the specification.

[0012] Such as figure 1 Shown: an automobile anti-skid device, comprising an automobile axle 1, a telescopic device 2 and a ring member 3, the height of the ring member 3 is the same as the car wheel 4, that is, the outer edge of the ring member and the car The wheels are flush with each other and are fixedly connected to the outer edge of the car wheel by bolts.

[0013] The ring member 3 is provided with a number of punching holes 4 at intervals; the telescopic device 2 is composed of a telescopic rod 21 and a hydraulic cylinder 22, the telescopic rod 21 is arranged inside the hydraulic cylinder 22, the hydraulic cylinder is arranged in the car On the side wall of the automobile wheel 4 with the axle 1 as the center, the top end of the telescopic rod 21 is connected with an arc-shaped plate 5, and the arc-shaped plate is evenly provided with regularly arranged cleats 6, and the cleats and the The punching hole 4 on the ring component corresponds to the punching hole 4 which can pass through the cleat 6 under the pressure of the hydraulic cylinder.

[0014] There are 4 hydraulic cylinders, which are fixed on the side walls of the wheels of the car and connected to the hydraulic system of the car. A hydraulic control system (not shown in the figure) is provided in the cab. When the switch is turned on, the hydraulic pressure The cylinder is pressurized to move the arc-shaped plate outward, and the cleats arranged on the arc-shaped plate will pass through the punching hole 4 of the ring member under the action of thrust to grasp the ground. On icy and snowy roads, the ice can be cut to increase the friction of the rest of the road. At the same time, the cleats can be retracted without affecting the normal driving of the wheels of the car.

[0015] As a preferred structure of the present invention, the ring member 3 is a steel ring, which increases the stability of the cleats on the arc-shaped plate and prevents the cleats from being broken under excessive stress.

[0016] As a preferred structure of the present invention, the cleats 6 are steel nails or rivets.

[0017] The above are only the preferred embodiments of the present invention and do not limit the present invention in any form. Any person skilled in the art can use the technical content disclosed above without departing from the scope of the technical solution of the present invention. Some changes or modifications are made into equivalent embodiments with equivalent changes, but any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solutions of the present invention still belong to Within the scope of the technical solution of the present invention.
