Abstract

The invention relates to a drum brake and a vehicle. The drum brake comprises a brake drum (1), a brake bottom plate (2), two brake shoes (3), an actuation device (4) and a locking piece (5). The first ends (31) of the brake shoes (3) are hinged to the brake bottom plate (2). The actuation device (4) is arranged between the second ends (32) of the two brake shoes (3). The first ends (31) of the brake shoes (3) form a starter gear (33). The locking piece (5) is installed on the brake bottom plate (2) and inserted in the starter gear (33) so that the locking piece (5) and the brake shoes (3) canform a ratchet and pawl mechanism. The drum brake comprises a small number of parts and is simple in structure and convenient to maintain, and a friction lining is convenient to install and detach.

Description

technical field [0001] The present disclosure relates to the field of vehicles, in particular, to a drum brake and a vehicle. Background technique [0002] The friction lining of the drum brake will continue to wear during use, so that the gap between the friction lining and the brake drum will continue to expand, which will increase the lag time of the brake mechanism operation and affect the safety of vehicle driving. In order to keep the gap between the friction lining and the brake drum within an appropriate range, an automatic adjustment gap adjustment mechanism such as a pawl bolt mechanism or a worm gear mechanism is designed. These gap adjustment mechanisms are complex in structure and have many components. , and the complex relationship increases the cost and maintenance difficulty of the brake. [0003] When the friction lining is worn to the point of needing to be replaced, it often needs to be disassembled together with the entire clearance adjustment mechanism....
