Problems solved by technology

[0003] In the traditional gearbox development test, there are mainly two ways to select and shift the test. The first is to manually complete the selection and shift test. Due to individual differences and the influence of the environment, the test results are greatly affected by human factors and are difficult to complete manually. 100,000 shift t

Abstract

The present invention proposes an experimental device for selecting and shifting gears of a gearbox. The scheme is as follows: the connecting jig of the transmission control mechanism is fixed at the middle position below the frame, and two power sources performing linear motion are arranged horizontally at a certain angle on the frame. , the two power sources performing linear motion are respectively fixed on the frame through the universal floating elbow joint support mechanism, the output shaft of the power source performing linear motion is connected to the mechanical drive mechanism, and the outer end of the mechanical drive mechanism is fixed to the shift lever block connection. During use, the shift lever fixing block is fixedly connected to the upper end of the shift lever. In the present invention, through the universal floating of two power sources that perform linear motion arranged at a certain angle, two sets of mechanical drive mechanisms that can overcome the interference of degrees of freedom can jointly complete the spherical motion of the point, and complete the shifting of the shift lever of the speed change control mechanism. The action can truly simulate the manual operation, so as to realize the experimental purpose of the gearbox.

Description

technical field [0001] The invention relates to the field of robots, in particular to an experimental device for gear selection and shifting of a gearbox. Background technique [0002] With the improvement of science and technology, in order to reduce the intensity of manual labor, improve production efficiency and test consistency and reliability, various robots and manipulators are applied. In the development and test process of manual transmissions such as commercial vehicles and passenger vehicles, the number of shifts between each gear of the transmission, the performance parameters between the shifting force and shifting displacement during shifting, etc. one of the main contents. [0003] In the traditional gearbox development test, there are mainly two ways to select and shift the test. The first is to manually complete the selection and shift test. Due to individual differences and the influence of the environment, the test results are greatly affected by human fac...
