Auxiliary braking system for truck

Abstract

The invention provides an auxiliary braking system for a truck. The system comprises a truck chassis, a plurality of auxiliary braking plates and a plurality of telescopic assemblies. Each telescopicassembly comprises a plurality of hydraulic telescopic fixing rods arranged at the left and right portions side by side, the upper portions of the hydraulic telescopic fixing rods are in sleeved connection through spline shafts, and the lower end of each hydraulic telescopic fixing rod is fixedly connected with the corresponding auxiliary braking plate. The two sides of each spline shaft are provided with outer threads, the truck chassis comprises two parallel chassis plates, the chassis plates are provided with threaded holes, and the two sides of each spline shaft are in threaded connectionwith the threaded holes of the two chassis plates respectively. The telescopic assemblies are arranged on the chassis plates front and back side by side, and the hydraulic telescopic fixing rods at the same side in the telescopic assemblies in the direction of the chassis plates are connected to the same auxiliary braking plate. When the truck encounters special road conditions, the hydraulic telescopic fixing rods drive the auxiliary braking plates to fall, the auxiliary braking plates conduct friction braking with the ground, in cooperation with an existing braking system of the truck, the truck is quickly braked, and the braking effect is good.

Description

technical field [0001] The invention relates to the field of truck brakes, in particular to an auxiliary brake system for trucks. Background technique [0002] Existing trucks completely rely on their own braking system to complete the braking. Although the existing truck braking system has a better braking effect on flat ground, on steep slopes or icy roads, the braking effect is poor only by using the existing braking system. The braking distance is too long, which poses a greater threat to the truck itself and other vehicles. Therefore, it is necessary to design a kind of auxiliary brake system, auxiliary truck brake, Contents of the invention [0003] Aiming at the problem of poor braking effect of existing trucks on special road surfaces, the invention provides an auxiliary braking system for trucks, which can provide auxiliary braking when the braking effect of the existing braking system is poor, so as to avoid traffic accidents. [0004] The present invention ado...
