Automobile anti-skid auxiliary braking safety device

Abstract

The invention provides an automobile anti-skid auxiliary braking safety device. A friction wheel disk is installed at the front end of a swing arm hinged to a base, the swing arm is in sliding fit with a guide plate fixed on the base, more than two positioning holes are arranged on the guide plate, positioning pins matched with the positioning holes are installed on the swing arm in penetrating mode, the upper end of each positioning pin is connected with an armature, an electric magnet is arranged above each armature, a first spring is arranged between each armature and the corresponding electric magnet, a motor is fixed on the base, a driven portion of an electromagnetic clutch connected onto a motor revolving shaft is connected with a winding wheel, the front end of a rope on the winding wheel is connected with the swing arm, and a second spring is connected between the swing arm and the base. When the automobile anti-skid auxiliary braking safety device is used, the base is fixed on an axle of an automobile and is close to a wheel of the automobile, and anti-skid performance or auxiliary braking performance can be achieved when the friction wheel disk butts against a position between the wheel and the ground.

Description

technical field [0001] The invention relates to an anti-skid device for motor vehicle wheels, in particular to an anti-skid and brake-assisting device for automobile wheels. Background technique [0002] At present, the commonly used wheel anti-skid devices are usually anti-skid chains or anti-skid shoes. The defects of existing anti-skid chains and anti-skid shoes in use are: 1. They need to be installed on the wheels when in use, and need to be removed from the wheels when not in use. 2. The contact surface with the tire is small, which is easy to wear the tire and damage the road surface; 3. The skid resistance is not good on the water and snow road; 4. It is not suitable for small cars; 5. There is no auxiliary brake function. Contents of the invention [0003] The object of the present invention is to provide an automobile anti-skid and brake-assisting safety device, which can realize anti-skid and brake-assisted safety device installed on the vehicle axle of the aut...
