Problems solved by technology

[0002] At present, vehicle deceleration and braking mainly rely on reducing the speed of the wheels, and then rely on the friction resistance between the tire and the ground, and the size of the friction resistance mainly depends on the contact friction area between the tire and the road surface and the pressure of the tire perpendicular to the road surface. The number of tires on a car is definite, and the contact friction area between the tires and the road is also definite. Therefore, when the speed of the vehicle is constant and the existing braking device of the vehicle is working normally, the sliding distance of the vehicle is certain, which cannot overcome the friction of the car. Inertia and bring the vehicle to a complete stop within a short distance

Abstract

The invention provides a vehicle emergency braking device, belongs to the technical field of automotive safety protection and achieves the effect that a vehicle is stopped at a short distance by using additional braking force. The vehicle emergency braking device is technically characterized by comprising a braking buffer part, a braking control unit and a braking part. The braking buffer part comprises a braking shaft, a pulley, a slotted steel tube, a sliding block and a wire rope. The braking shaft is horizontally fixed to a crossbeam of the vehicle and located at the position of the center of gravity of the vehicle, the pulley is installed at the middle of the braking shaft, the slotted steel tube is arranged at the crossbeam of a vehicle chassis, the sliding block is installed in one end of the slotted steel tube in a sleeving manner, the other end of the slotted steel tube is provided with a round hole and is close to the pulley, one end of the wire rope is connected to the sliding block, the wire rope is arranged along the slotted steel tube, and the other end of the wire rope penetrates out of the round hole, is wound on the pulley and is then connected to the braking part. The vehicle emergency braking device is particularly suitable for emergency braking of the vehicle and the vehicle can be stopped at a short distance.
