Abstract

The invention discloses a fatigue endurance test measuring system of an automobile automatic gearbox P-gear parking mechanism. The fatigue endurance test measuring system comprises a test device part and a measuring control part. The test device part comprises an installing base, the automatic gearbox to be measured, a gearbox installing basic frame, a torque sensor, a loader, a brake device, a driving motor, a gear shifting device and a gear shifting mechanical arm. The measuring control part comprises a computer, a braking controller, a loading controller, a data collector and a driving motor controller. Test measuring can be performed on the fatigue life of the P-gear parking mechanism through simulating the test working conditions, on an ascending road and a descending road, of the automatic gearbox, so that the reliability and accuracy of fatigue endurance tests of the automatic gearbox P-gear parking mechanism are improved.

Description

technical field [0001] The invention relates to the technical field of automobile testing, in particular to a P-range parking performance test and measurement system for an automatic transmission in an automobile power system, in particular to a fatigue endurance test and measurement system for a P-range parking mechanism of an automatic transmission for automobiles. Background technique [0002] With the development of automobile transmission technology, automatic transmission has become an important development direction of automobile transmission due to its characteristics of easy operation, comfortable driving and smooth shifting. The P-block parking mechanism is an important part of the automatic transmission. The P-block parking mechanism is composed of a locking gear, a lock pin pawl, and a set of parking actuators. Usually, the locking gear is rigidly connected to the output shaft of the transmission. The pin pawl and the parking actuator are fixed to the transmissio...
