Description

Technical Field

[0001] The utility model relates to the technical field of brake devices, in particular to a brake device for a carriage. Background Art

[0002] Currently, due to differences in manufacturers, varying designer experience, and varying performance requirements from client to client, sightseeing trains and related vehicles require customized designs each time, generally defying standardization and unification. Consequently, the functions and performance of each vehicle's systems vary. This can easily lead to variations in the effectiveness of the vehicle's most critical braking system. These differences primarily manifest in the use of different end-of-line braking methods—shoe brakes, drum brakes, disc brakes, and chuck brakes—as well as in the use of different brake valves and control logic. These varying braking methods and control logic combinations result in varying braking performance.

[0003] For gentle slopes or lower speeds, these differences are not obvious on the train. However, once the slope is steep or the running speed is high, the braking effect of some combinations is significantly lower, which may result in excessively long braking distances or even erroneous actions.
