An embracing braking device for a truck

Abstract

The invention relates to an embracing braking device of a truck, comprising a braking base plate, a braking shoe and a braking wheel, one end of the braking shoe is hinged with the braking base plate, and the outer peripheral surface of the braking wheel is connected to the braking shoe The inner peripheral surface of the brake shoe is configured with the other end of the brake shoe and the linkage mechanism. The linkage mechanism includes a drive shaft, a left drive arm and a right drive arm. The left and right drive arms are symmetrically arranged at both ends of the drive shaft. The outer end face is provided with a boss and a heat dissipation fin, which is connected with the wheel hub through bolts. The invention has reliable braking performance, good heat dissipation effect and high applicability.

Description

technical field [0001] The invention belongs to the technical field of automobile braking devices, and in particular relates to a clutch 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 clutch brake device for trucks, which not only has a simple structure and reasonable setting, but also has qu...
