Abstract

The invention discloses a wear early-warning control method for an automatic gearbox gear shifting system. The wear early-warning control method for the automatic gearbox gear shifting system is applied to a speed changing system; the speed changing system comprises a gearbox and a gearbox controller; the gearbox comprises the gear shifting system; and the wear early-warning control method for theautomatic gearbox gear shifting system includes the following steps that 1, a gear setting program of the gearbox controller is started; step 2, D_L0 and D_R0 are identified; step 3, D is calculated;step 4, deltaD is calculated; and step 5, wear early-warning is performed. The wear early-warning control method for the automatic gearbox gear shifting system aims to solve the problems that gearboxcontroller software in the prior art cannot effectively identify the wear loss and perform early-warning control and the occurrence frequency of wear faults of the gear shifting system is increased.

Description

technical field [0001] The invention belongs to the technical field of transmission systems, and in particular relates to an early warning control method for wear of an automatic transmission shift system. Background technique [0002] figure 1 It is a typical transmission fork shift structure. The shift pad 1 is driven by an external actuator to swing around the center of rotation. The shift fork shaft 2 and the shift fork 3 are assembled as a whole, and the swing of the shift dial 1 will drive the shift fork 3 and the shift fork shaft 2 to perform linear motion. The shift fork 3 drives the meshing gear sleeve 4 to also perform linear motion. figure 1 There is a meshing tooth on the left and right sides of the middle meshing tooth sleeve. Take the left meshing tooth 5 as an example. When the meshing tooth sleeve 4 moves to the left, it will mesh with the meshing tooth 5, and the torque of the gearbox can pass through the transmission gear. 6 is transmitted to the meshin...
