Auxiliary device for braking vehicle in snowfield

Abstract

The invention relates to the technical field of driving safety equipment, and discloses an auxiliary device for vehicle snowfield braking, which comprises a containing box and a guide groove which are fixedly connected with an automobile chassis, the containing box and the guide groove are provided with two groups of discrete sides, and a plurality of soft and foldable anti-skid gaskets are arranged in the containing box. According to the auxiliary device for braking the vehicle in the snowfield, when braking is needed or the vehicle slips, the anti-skid gaskets are conveyed to the front portions of the wheels, the friction force between the wheels and the ground is increased, the landing force is increased, the anti-skid gaskets fly out continuously, the friction force of the vehicle on a braking road section is guaranteed, the vehicle is stopped rapidly, meanwhile, slipping of the wheels can be avoided, and the service life of the vehicle is prolonged. In addition, due to the fact that the friction force between the wheels and the ground is improved through the anti-skid gaskets, the braking capacity can be improved and braking timeliness can be guaranteed by throwing the anti-skid gaskets before emergency braking, and when the wheels slide, the friction force between the wheels and the ground can be improved by throwing the anti-skid gaskets, sliding is stopped, and a vehicle can stop rapidly.

Description

Technical field [0001] The present invention relates to the technical field of driving safety equipment, specifically a vehicle snow brake auxiliary device. Background [0002] Cars greatly facilitate people's lives, increase people's activity space, and therefore, people have a greater dependence on cars, even in some harsh environments, we still need to use vehicles to travel. [0003] The driving and braking of the car depends on the friction between the wheels and the ground, and when driving in the snow, the road surface is slippery, the car is braking, on the one hand, due to the small friction, the wheels are slipping, it is difficult to stop or the braking distance is too long, especially in the long downhill section, it is difficult to stop, it is easy to cause accidents, on the other hand, when the car brakes, due to the different ground conditions, it is not easy to make the braking force of the front and rear wheels different, so the vehicle sideslips and deviates fr...

AI Technical Summary

Problems solved by technology

[0003] The driving and braking of a car depend on the friction between the wheels and the ground. When driving in the snow, the road surface is slippery. When the car is braking, on the one hand, due to the small friction, the wheels will slip, making it difficult to stop or the braking distance If it is too long, especially on the long downhill section, it is difficult to stop, and it is easy to cause accidents. On the other hand, when the car is braking, due to the different ground conditions, it is not easy to make the braking force of the front and rear wheels different, so the vehicle skids and deviates from the normal driving section

[0004] Furthermore, since the friction between the wheels of the car and the road surface is small, braking in the snow is generally decelerated by the drag of the engine to avoid the wheels from locking up and slipping with the ground, that is, in the snow, emergency braking is usually not possible , so it is impossible to stop in time in an emergency. Secondly, in an emergency, it is easy for people to step on the brakes instinctively, making the brakes ineffective.
