Vehicle emergency braking device

Abstract

The invention relates to a vehicle emergency braking device which is installed on a vehicle body and comprises braking buttons, at least two storage boxes and braking device bodies. The braking buttons are arranged in a driving cab, and the storage boxes are fixed to cross beams on the two sides of the vehicle body correspondingly and are located in front of a rear wheel of the vehicle body; the storage boxes comprise box bodies with the lower ends being opened and storage box covers capable of being connected with the box bodies in an opening-and-closing mode; door lock switches are arranged on the storage box covers correspondingly and are electrically connected with the braking buttons, and the braking device bodies are arranged in the storage boxes in a foldable mode and comprise mooring ropes, braking components and braking sliding plates; the first ends of the mooring ropes are connected with the cross beams, and the second ends of the mooring ropes are connected with the first ends of the braking components; and the second ends of the braking components are flexibly connected with the braking sliding plates. According to the vehicle emergency braking device, during emergency braking of a vehicle rear tire, a vehicle and the ground can be in a sliding friction state, the friction coefficient is increased, good braking force is obtained, the braking property of the vehicle is improved, and the risk of traffic accidents is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile braking, and more specifically relates to a vehicle emergency braking device. Background technique [0002] With the development of science and technology, automobiles have become one of the indispensable tools in people's lives, especially heavy-duty vehicles or long-distance buses. The transportation of heavy-duty vehicles plays a vital role in the era of the Internet of Things; and long-distance buses are one of the best choices for people to travel. [0003] However, whether it is a heavy-duty vehicle or a long-distance bus, the vehicle is braked by the reaction force of the friction between the tire and the ground when braking, but even with the current ABS system, the braking force between the rear wheel and the ground The power cannot be greater than the maximum static friction between the rear wheels and the ground, and the braking force is limited. As a result, vehicles traveling at h...

Problems solved by technology

[0003] However, whether it is a heavy-duty vehicle or a long-distance bus, the vehicle is braked by the reaction force of the friction between the tire and the ground when braking, but even with the current ABS system, the braking force between the rear wheel and the ground The power cannot be greater than the maximum static friction between the rear wheels and the ground, and the braking force is limited. As a result, vehicles traveling at high speeds are too fast and the braking distance is too long, which increases the risk of traffic accidents, especially for heavy-duty vehicles. When fully loaded, the risk index is even higher
