Automotive transmission on-line loading test bench

Abstract

The invention provides an automotive transmission on-line loading test bench which comprises a mechanical body. An operation control cabinet is arranged on one side of the mechanical body. The operation control cabinet is connected with an electrical control cabinet. The electrical control cabinet is arranged on one side of the mechanical body. An output end sliding table is arranged on the upper end of the mechanical body. A loading frequency conversion servo motor is arranged on the output end sliding table. A loading flexible driving mechanism is arranged on the loading frequency conversion servo motor. A test positioning trolley is arranged on the outer end of the loading flexible driving mechanism. The test positioning trolley is arranged on a transitional connecting plate. One side of the transitional connecting plate is connected with a driving transmission main shaft assembly through a spline sleeve. The driving transmission main shaft assembly is connected with a driving frequency conversion servo motor. According to the invention, the test bench has the advantages of quick and easy clamping, being safe and reliable, accurate positioning, high-speed rotation and great shock absorption, and is suitable for the test of a variety of products; less workshop site resources are occupied, so that the resources are orderly; and the field production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of performance / function testing of automobile transmissions, in particular to an on-line loading test bench for automobile transmissions. Background technique [0002] As customers have higher and higher requirements for transmissions, it is not only necessary to conduct various tests to verify product reliability during the research and development of transmissions, but also to test, verify and evaluate various performances and functions when they are rolled off the assembly line. , to detect and expose possible problem points in advance, thereby reducing the risk of failure in the product market, and the electric closed loading test bench can quickly detect the quality of off-line products, and it is more and more widely used at present, but it is affected by the existing conventional mechanical structure and so on. After the longitudinal transmission is clamped, the cantilever is too long, and it is easy ...

[0002] As customers have higher and higher requirements for transmissions, it is not only necessary to conduct various tests to verify product reliability during the research and development of transmissions, but also to test, verify and evaluate various performances and functions when they are rolled off the assembly line. , to detect and expose possible problem points in advance, thereby reducing the risk of failure in the product market, and the electric closed loading test bench can quickly detect the quality of off-line products, and it is more and more widely used at present, but it is affected by the existing conventional mechanical structure and so on. After the longitudinal transmission is clamped, the cantilever is too long, and it is easy to generate vibration during high-speed operation, and the overall operation effect is not ideal
