Embodiment

[0021] Embodiment: Referring to Fig. 1 and Fig. 2, the present invention includes a cover plate 1 and a cylindrical support frame 2, a folded airbag 3 and a heat shield 4, a steel back 5 and a brake block 6, a support pin 8 and a return spring 9. Fan blades 12, cylinders 14, levers 19 and other system components. The cover plate 1 and the support frame 2 are joined to form a cylindrical structure, which is the backbone and base of the brake of the present invention. Referring to Fig. 4 and Fig. 5, the fully-sealed air chamber formed by the outer diaphragm 25 of the air bag and the inner diaphragm 26 of the air bag by the folded air bag 3 is the most important key part of the brake of the present invention. And measures such as tight embedding and strong adhesion are guaranteed. The steel back and brake block, the support pin and the return spring are the execution parts to ensure the braking function. With the cylindrical support frame 2 as the base, the folded airbag 3 is t...

Abstract

The invention comprises a cylindrical support, and outside the support are disposed a cover plate, a gasbag, an insulating plate, a steel backing and a brake shoe in order. Between the adjacent brake shoes is disposed a support pin and two ends of which are inserted into the corresponding holes on the lower edge and the cover plate of the cylindrical support. The mouth of the gasbag is in communication with the air inlet on the cylindrical support through the passage in the cylindrical support, and extends to a gas holder from the air inlet. A return spring is disposed between the support pin and the steel backing, and the base of the return spring is disposed on the support pin. On the inside wall of the cylindrical support or on the cover plate is disposed a parking braking cylinder and on which connected a penetrator ram is disposed under the gasbag or the brake shoe.

Description

technical field [0001] The invention relates to the field of brakes of automobiles and other motor vehicles, in particular to a corrugated air bag cylinder brake. Background technique [0002] At present, the shoe brakes commonly used in automobiles and other motor vehicles have a history of more than 120 years. The shoe brakes have inconsistent braking torque, easy to run off and lock, loud brake whistle, short life of brake blocks, and difficult to adjust the clearance, etc. shortcoming.
