Abstract

The invention discloses a comprehensive maintenance test bench. The test bench comprises a test bench main body, an operation panel, a dryer test bench frame, a brake chief pump test device, a valve test frame, an air supply device, a push-pull fixed bench frame, a connecting pipeline and other detection devices. One or more to-be-tested parts, a barometer, an air pressure control switch and the air supply device fixed on the comprehensive maintenance test bench are connected through the connecting pipeline, and a corresponding air passage is formed. The comprehensive maintenance test bench performs targeted design in view of the maintenance requirements of the existing brake system, performance tests of various pure electric bus brake valves, brake air chambers, brake calipers and the like at present can be well executed, and the actual use requirements are met. Performance tests are carried out on all parts of the brake system through the comprehensive maintenance test bench, the assembly repair reliability can be effectively improved, assembly part replacement is reduced, and the maintenance cost is reduced.

Description

technical field

[0001] The invention relates to the field of vehicle maintenance, in particular to a comprehensive maintenance test stand. Background technique

[0002] In the braking system of large vehicles, the air system is a very important part, which is mainly used to provide a strong enough force for the braking mechanism of the vehicle to achieve the effects of vehicle braking and parking.

[0003] For the driving safety of large vehicles, the braking system is of great significance. In the process of vehicle maintenance, it is necessary to use testing equipment to detect the braking system of the vehicle to ensure that the system meets the standard state of normal use.

[0004] Due to the increase in the periodic maintenance of the air circuit of existing large vehicles (such as BYD buses), the number of replaced air circuit assemblies has increased sharply, and the traditional air circuit maintenance test equipment has been difficult to meet the requirements of the...
