Abstract

The invention discloses a simulation detecting device of a magnet magnetic field signal of a position sensor of a shifting fork assembly. The simulation detecting device is composed of a detection bench, a positioning tool, a linear guiding mechanism, a driving device and a magnetic field signal detecting sensor, wherein the positioning tool, the linear guiding mechanism, the driving device and the magnetic field signal detecting sensor are arranged at the detection bench. The linear guiding mechanism is fixed at the detection bench relatively. The positioning tool for loading a shifting forkassembly with a shifting fork assembling position sensor magnet is arranged at the linear guiding mechanism and is connected to the driving device; the driving device can drive the positioning tool, together with the loaded shifting fork assembly, to move along a guiding direction of the linear guiding mechanism so as to simulate the shifting fork shift travel. The magnetic field signal detectingsensor is arranged at the simulation detecting device for detecting and simulating the shifting fork shift travel. With the detecting device, the high delivery yield of the shifting fork is ensured; the usage reliability is improved; and thus the assembling quality of the speed changer is enhanced.

Description

technical field [0001] The invention relates to the technical field of auto parts detection, in particular to a device for simulating and detecting the magnet magnetic field signal of a position sensor of a shift fork assembly in a shifting stroke. Background technique [0002] In order to enable the transmission control system to monitor the shift stroke of the shift fork and identify whether the transmission has completed shifting normally, the position sensor (in the transmission, a component used to monitor the signal output of the shift fork magnet and perform signal conversion) is currently used. (In the transmission, the position signal used to push the synchronizer gear sleeve to engage and separate from the shift gear to achieve the change of the transmission gear) is provided to the control system. Specifically, a magnet can be installed on the shift fork, through the magnet and The shift fork moves together to change the magnetic field signal at the location of th...

Problems solved by technology

[0005] On the one hand, the magnet magnetic field signal detection of the position sensor of the shift fork assembly is detected when the transmission is assembled and rolled off the assembly line. When there is a shift signal failure, the shift fork assembly needs to be unpacked and replaced, which is time-consuming, laborious and costly to rework , a large loss of quality

[0006] On the other hand, when there is a shift signal failure in the transmission, it is impossible to quickly determine the root cause of the failure due to various factors such as the compliance of the shift fork assembly, the compliance of the sensor, and the compliance of the transmission assembly.
