Abstract

The invention discloses a test method and device for the clutch torque transmission characteristic in a transmission assembly. The test method comprises steps that a mass flywheel of the transmissionassembly is fixed, a transmission is switched to a forward gear, and a clutch is turned on; a long half shaft and a short half shaft are driven to rotate to drive a transmission input shaft of the transmission assembly to rotate; after the transmission input shaft rotates at the target speed, a platen of the clutch is pushed to move toward a driven plate, and the input torque transmitted by the clutch to the transmission input shaft is acquired in real time; when the acquired input torque reaches the target torque, pushing of the platen is stopped, and the current movement amount of the platenis recorded. The test method is advantaged in that test cost of the clutch torque transmission characteristic in the transmission assembly can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of automobile transmission bench tests, in particular to a method and device for testing clutch torque transmission characteristics based on a three-motor transmission assembly bench. Background technique [0002] When testing the transmission assembly of an automobile, it is necessary to perform a torque transmission characteristic test on the clutch. The usual practice is to separate the clutch from the transmission assembly and install it on a special clutch test bench for testing. After the clutch is stripped separately, it is necessary to design a hydraulic or mechanical function module to control the displacement of the clutch during the test and record it in real time. [0003] Among them, the structure of the hydraulic or mechanical function module is complicated, and the design cost is high, and the function of the clutch test bench is single, which increases the marginal cost. [0004] Therefore, ...
