Description

technical field [0001] The invention relates to the technical field of mechanical transmission and testing, in particular to a shift manipulation testing system and method for high-power mechanical transmissions. Background technique [0002] As the core key component of high-power mechanical transmission, the gear shifting mechanism plays an important role in ensuring the reliable operation of special vehicle chassis. Due to the characteristics of heavy load and high power on the chassis of special vehicles, the gear shifting of the synchronizer is relatively heavy; at the same time, in order to meet the needs of the space layout of the vehicle, the operating mechanism of the high-power transmission adopts the form of double flexible shafts, and the flexible shafts are compared with The rigid operating mechanism has strong nonlinearity in force and stroke, which also makes the design of the shift operating mechanism and the matching of the shift assist system more complicat...

AI Technical Summary

Problems solved by technology

Due to the large load of the shift control mechanism and the complicated transmission path, it is difficult to determine the boundaries of each part, and it is difficult to locate once a problem occurs

The second problem is that each part of the gear shifting mechanism of a high-power mechanical transmission is designed and tested separately, so various performance and bench reliability assessments are often carried out on a separate mechanism, but due to the operating conditions of special vehicle chassis Due to the particularity, many new problems will still be exposed in the actual sports car process, and the bench test coverage is insufficient
