AI Technical Summary
Existing technology requires disassembling multiple parts of the mining truck to lock the gearbox output end, and lacks universal tooling to adapt to the different engine and gearbox positions of mining trucks, resulting in time-consuming and labor-intensive operation, which is not conducive to single-person operation.
An auxiliary tooling for testing gearbox stall was designed, including a base plate, a base upright plate, a telescopic support plate, and a transition plate. The gearbox output end is locked through connecting holes and fixing bolts, which can adapt to the testing needs of different mining trucks.
It enables single-person operation to lock the gearbox output end without disassembling vehicle parts, improving the tooling's flexibility and versatility, and meeting the testing needs of different vehicle models.
