Problems solved by technology
[0003] The current vehicles brake the vehicle through the reaction force of the friction force between the tire and the ground, although some improvements have been proposed, for example, the use of ABS (anti-lock brake) device can increase the size of the tire and the ground to a certain extent. The friction between the ground, however, because the contact area between the tire and the ground basically does not change, the braking force obtained during emergency braking is also limited
Therefore, when the vehicle running at high speed brakes suddenly, its braking effect is still not ideal enough.

Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] refer to figure 1 , figure 2 , is a kind of vehicle emergency auxiliary braking device of the present invention, wherein, lifting mechanism comprises cylinder 2, is arranged on the side of cylinder 2 and is connected to the return spring 3 of cylinder 2 two ends, communicates with the compressed gas cylinder of cylinder 2 through pipeline (not shown in the figure Schematic), the control valve set on the pipeline (not shown in the figure). The compressed gas cylinder provides the power source, and the control valve is generally a solenoid valve, which is used to control the lowering of the cylinder 2; the exhaust valve of the cylinder 2 itself and the return spring 3 are used to control the lifting of the cylinder. In this embodiment, one end of the cylinder 2 is movably connected to the vehicle chassis 1, and the other end i...

The invention relates to a vehicle braking technology, and discloses an emergent auxiliary braking device for a vehicle. The device is characterized by comprising a lifting mechanism, an auxiliary wheel frame and an auxiliary wheel arranged on the auxiliary wheel frame, wherein one end of the lifting mechanism is connected to a chassis of the vehicle, and the other end of the lifting mechanism is connected to the auxiliary wheel frame. The emergent auxiliary braking device has a simple structure, is convenient to mount, and can effectively shorten a braking distance of a high-speed travelling vehicle in the emergent braking process and improve the travelling safety of the vehicle.
Description
technical field [0001] The invention relates to vehicle braking technology, in particular to a vehicle emergency auxiliary braking device. technical background [0002] With the development of economy and society, automobiles become more and more popular, and the maximum speed of automobiles also becomes higher and higher, which also brings certain safety problems. Because the higher the vehicle speed, the longer the braking distance, the more likely to cause traffic accidents. At present, most of the traffic accidents on the highway are caused by too long braking distance. Therefore, it is particularly important to study the vehicle auxiliary braking device that can reduce the braking distance. [0003] The current vehicles brake the vehicle through the reaction force of the friction force between the tire and the ground, although some improvements have been proposed, for example, the use of ABS (anti-lock brake) device can increase the size of the tire and the ground to ...
