Embodiment Construction

[0042] It should be noted that although the drawings and the following description divide the present invention into multiple embodiments for description, those skilled in the art understand that, in the case of no conflict, each embodiment in the present application and the embodiment The features in can be combined with each other.

[0043] figure 1 The scheme of the end-of-line test bench equipped with an electric drive transmission is shown. exist figure 1 In the above, the electric drive transmission to be tested includes the transmission under test 5, and the transmission under test 5 includes a housing, an internal gear transmission and a differential. In addition, the tested transmission 5 also includes electronic actuators and sensors, such as solenoid valves, temperature sensors and the like. Two load motors 1a, 1b are symmetrically arranged at both ends of the two output shafts of the differential of the transmission under test 5, and these two load motors are us...

Abstract

The invention discloses a test board. The test board is used for testing a transmission, and comprises a motor controller used for controlling a motor driving the tested transmission, a transmission controller, a control cabinet, and a load motor used for being connected with an output shaft of the tested transmission. When the tested transmission is in an electric drive assembly, the motor controller controls the motor in the electric drive assembly; and when the tested transmission is an independent transmission, the motor controller controls another motor. The invention further provides a test method based on the test board. According to the invention, collinear compatibility of an electric drive assembly test and an electric drive transmission test can be realized, the utilization rate of the test board is improved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of vehicles, and in particular relates to a test bench and a test method based on the test bench. Background technique [0002] In the field of new energy vehicle powertrain, the powertrain is divided into split type and integrated type. The split type means that the motor and the transmission are independent units, which have independent housings and can work independently, and the two are connected together by splines, bolts and other parts. The integrated type means that the motor and the transmission are designed inside an integrated housing structure, and the two are designed in one piece and cannot work independently. Due to the coexistence of split and integrated new energy vehicle powertrains, the two products need to be treated separately during production testing. [0003] Usually, after the electric drive assembly and the electric drive transmission are assembled on the production line, they must be insta...
