Passenger car control shaft assembly gear selection and shift performance test testbed

Abstract

The present invention discloses a passenger car control shaft assembly gear selection and shift performance test testbed. The testbed comprises a test fixing mechanism for fixing a control shaft assembly, a servo drive mechanism for driving the control shaft assembly to move vertically and rotatably to test the gear selection and shift performance and a servo control mechanism for controlling the servo drive mechanism to move, and also comprises a liquid crystal display cabinet electrically connected with the servo control mechanism and used for the data real-time output. The test testbed has a gear selection and shift transmission mechanism of high response and high reliability, totally satisfies the combined gear shift test of any gear, and can test a gear selection force, a gear shift force, a gear selection stroke and a gear shift angle during a control shaft assembly gear selection and shift process, so that the passenger car control shaft assembly gear selection and shift performance test testbed is compact in structure and high in automation degree, and can detect the production quality of the control shaft assembly products efficiently and at a high precision.

Description

technical field [0001] The invention belongs to the technical field of detection devices, and in particular relates to a test bench for selecting and shifting performance of a control shaft assembly of a passenger car. Background technique [0002] In automobile production, the quality of the shifting performance directly affects the use of the automobile, but the detection means for the shifting performance of squadron cars in the prior art is less, and there is no test platform with high feasibility and strong versatility. Relying on manual detection alone will increase the false detection rate on the one hand, and lead to the consumption of manpower and material resources on the other hand. [0003] Chinese patent document CN 101566521A discloses an automobile shifter assembly performance testing workstation and its testing method. The workstation controls the shifter handle and the shifter body rotating around two mutually perpendicular rotation axes to obtain the The s...

[0002] In automobile production, the quality of the shifting performance directly affects the use of the car. However, there are few detection methods for the shifting performance of squadron cars in the prior art, and there is no test platform with high feasibility and strong versatility.

Relying on manual detection alone will increase the false detection rate on the one hand, and lead to the consumption of manpower and material resources on the other hand

[0003] Chinese patent document CN 101566521A discloses an automobile shifter assembly performance testing workstation and its testing method. The workstation controls the shifter handle and the shifter body rotating around two mutually perpendicular rotation axes to obtain the The spherical movement of the shifter handle relative to the shifter body simulates the shifting process in reality, but this kind of simulation makes the workbench occupy a large area and the implementation is more complicated, which is not conducive to a large number of popularization and application in the industry
