Abstract

The invention discloses a spring durability detection device and belongs to the technical field of detection devices. The spring durability detection device comprises a rack, wherein the rack is provided with a crank and rocker mechanism which is driven by a first power device, the crank and rocker mechanism is connected with a gear selection disc through an articulated shaft which is mounted on the rack, and a spring fixing frame is arranged at a position, corresponding to the gear selection disc, on the rack. The spring durability detection device provided by the invention is simple in structure, and low in cost; the durability detection on a plate spring used on an automatic transmission is realized.

Description

technical field [0001] The invention belongs to the technical field of detection devices, in particular to a spring durability detection device. Background technique [0002] The shifting smoothness of automatic transmissions is still a worldwide problem, and major automatic transmission manufacturers are still unable to completely avoid vibration and shock problems. The improvement of driving comfort must rely on an excellent shift control strategy, and the reliability of hardware performance is the foundation. The rapid response and establishment of automatic transmission oil pressure and the stability of oil pressure are directly related to the performance of the coil spring on the valve plate; on the other hand, the performance of the parking mechanism is also closely related to the torsion spring and leaf spring . [0003] Although there are also durability testing devices for springs in the prior art, most of them are durability testing devices for coil springs. At p...
