Problems solved by technology

[0002] Although the existing drum brakes of automobiles have been improved for many times, their braking performance has been perfected, but when braking or emergency braking under heavy load or down a long slope, the braking often lags behind, and the braking distance becomes longer. Incomplete return after moving causes dragging of the brakes, which becomes a major safety hazard such as increased fuel consumption during driving. Moreover, the contact surface of the cam brake is small, the stress is large, the amount of expansion is small, and the reliability is low.

Abstract

The invention relates to a chain type braking device of a heavy vehicle. The chain type braking device comprises a brake bottom plate, a brake shoe and a brake wheel. One end of the brake shoe is hinged to the brake bottom plate. The outer circumferential face of the brake wheel is matched with the inner circumferential face of the brake shoe. The other end of the brake shoe is matched with a linkage mechanism. The linkage mechanism comprises a linkage shaft, a left connection plate and a right connection plate. The left connection plate and the right connection plate are symmetrically arranged at the two ends of the linkage shaft. The end face of the outer side of the brake wheel is connected with a transition disc and is connected with a hub through the transition disc. The chain type braking device is reliable in brake performance, good in cooling effect and high in applicability.

Description

technical field [0001] The invention belongs to the technical field of automobile braking devices, in particular to a chain type braking device for trucks. Background technique [0002] Although the existing drum brakes of automobiles have been improved for many times, their braking performance has been perfected, but when braking or emergency braking under heavy load or down a long slope, the braking often lags behind, and the braking distance becomes longer. Incomplete return after moving causes brake dragging, which becomes a major safety hazard such as increased fuel consumption during vehicle driving. Moreover, the contact surface of the cam brake is small, the stress is large, the amount of expansion is small, and the reliability is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a chain brake device for trucks, which not only has a simple structure and reasonable setting, but also has quick braking re...
