Abstract

The utility model relates to a bench test system for a compound automatic transmission of a vehicle, which belongs to the technical field of vehicle testing. It mainly tests the performance of the compound automatic transmission, especially the speed ratio control effect of the continuously variable transmission, the stepless switching control effect, and the power, economy and transmission efficiency of the compound automatic transmission. It can solve the main performance test problems of compound automatic transmissions. The present invention is mainly composed of three parts: control computer, test stand, and roller test mechanism. It is characterized in that: the sensors on the test stand and roller test mechanism measure signals such as speed, fuel consumption, torque, etc., and the control computer performs calculations according to the signals of each sensor. , to get the quantitative indicators of compound automatic transmission's economy, power, speed ratio control and so on. The invention is specially used for testing the economy, power, transmission efficiency, speed ratio control effect and switching control effect of the compound automatic transmission.

Description

technical field [0001] The invention relates to a bench testing system for a compound automatic transmission of an automobile, which belongs to the technical field of automobile testing. Background technique [0002] Invention patent 200710115088.1 discloses a compound automobile transmission, on the basis of the metal belt continuously variable transmission, a stepped transmission mechanism is added, and the metal belt continuously variable transmission and the stepped transmission constitute the compound automobile transmission. According to the needs of the working conditions of the vehicle, the continuously variable transmission and the stepped transmission can be respectively realized. [0003] At present, there is no bench test system that can be directly used for the test of the performance of the above-mentioned compound automatic transmission. The present invention is a set of bench test device invented for the bench test of the above-mentioned compound automatic tr...
