Abstract

The invention provides a test stand for a torque converter transmission case which is applied to the performance test and delivery test of a torque converter transmission case and has the advantages of simple structure, reliability in operation and high cost performance and realizes replacement convenience of the tested transmission case. An input rotation speed torque sensor (3) is mounted between a power source diesel engine (1) and the tested torque converter transmission case (5); an output rotation speed torque sensor (7) is mounted between the tested torque converter transmission case (5) and a two-level reduction gearbox (9); and a dynamometer AC (alternating current) generator (11) is used as a load, and a dynamometer adopts an external forced ventilator for cooling and a synchronous traction generator capable of realizing positive/negative rotation so as to meet the requirement of performing a reverse test by using the transmission case.

Description

technical field [0001] The invention relates to a torque converter transmission box test bench, which is used for the performance test and delivery test of the torque converter transmission box. It belongs to the technical field of test equipment. Background technique [0002] At present, with the continuous acceleration of the introduction, digestion, absorption and localization of railway technology, the imported technology has gradually developed from electric locomotives, diesel locomotives, and EMUs to hydraulic transmission railcars for engineering operations, and hydraulic power trains for rail operating vehicles. The torque converter gearbox has also joined the ranks of technology introduction, digestion, absorption and localization. With the deepening of the localization process of the transmission box of the hydraulic torque converter, the performance evaluation of the manufacturing quality of the transmission box after the localization is imminent, and it is urge...
