Description

TECHNICAL FIELD

[0001] The utility model belongs to commercial vehicle test device technical field, concretely relates to a kind of operating mechanism for assisting commercial vehicle simulation test. BACKGROUND

[0002] In the road simulation fatigue test of commercial vehicle, test personnel usually need to manually operate vehicle retarder to switch high-low gear. This manual operation not only increases the complexity of the test, but also can lead to inaccurate test results, especially in long-time test, the fatigue of test personnel can further affect the stability and reliability of the test. Specifically, the existing manual control mode has the following problems:

[0003] 1. Low degree of automation: the existing retarder control mode mainly relies on manual operation of test personnel, lacks automatic control function. Test personnel is prone to misoperation due to fatigue in long-time test, which affects the accuracy of test data and the safety of test. In addition, manual operation is difficult to ensure the accuracy and consistency of each operation, especially in high-frequency gear shifting operation, the reaction speed and operation precision of test personnel may not meet the test requirements.

[0004] 2. Limited scope of application: the existing auxiliary retarder control mechanism is usually designed for specific vehicle models or specific types of retarder, lacks universality. For example, some control mechanisms are only suitable for the retarder of a certain commercial vehicle, and cannot be directly applied to other vehicle models or different types of retarder. This limitation leads to frequent replacement or adjustment of control mechanism when testing multiple vehicle models or multiple types of retarder, increasing the complexity and cost of test.
