Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Depend on figure 1 As shown, the shifter performance testing device of the present invention includes a workbench 1, a driving mechanism 2, a base mechanism 3, a load mechanism 4, two force sensors 5, two displacement sensors 6 and a controller.

[0032] Depend on figure 2 As shown, the drive mechanism 2 includes a support frame 201 arranged on the workbench 1. The support frame 201 is provided with a power mechanism 202 that can move up and down and position the output torque. The power mechanism 202 includes a third servo motor 2022 and an output torque. The shaft 2021 and the third servo motor 2022 drive the output shaft 2021 to rotate through the transmission mechanism. The output shaft 2021 of the power mechanism 202 is arranged horizontally and is connected with a swing arm 203. The swing arm 203 is vertically arranged....

Abstract

The invention discloses a gear shifter performance testing device. According to the gear shifter performance testing device, the output shaft of a power mechanism rotates to drive a swing arm to swing, and the swing arm drives a swing rod to move; when the wing rod moves, two force sensors drives the handle ball of a gear shifter to swing to simulate gear shifting of the gear shifter, so that the force sensors can in real time measure the force for driving the handle ball to swing; the measuring heads of two displacement sensors abut against the two force sensors and accordingly the two displacement sensors can in real time measure the forward and backward swing distance of the handle ball. The gear shifter performance testing device is relatively accurate in testing data.

Description

technical field [0001] The invention relates to a gear shifter performance testing device. Background technique [0002] The shifter is the main part of the car, and its quality directly affects the handling of the car. If an unqualified shifter is installed on the car, it will affect the comfort and safety of the car's handling. After the production of the gear shifter is completed, it is necessary to perform a performance test on the gear shifter. [0003] At present, the test of the shifter is generally through the manipulator to drive the handle ball of the shifter to shift gears. When the manipulator drives the handle ball of the shifter to shift gears, the driving force and stroke applied by the manipulator are measured and a curve is formed. Figure to judge whether the shifter is qualified. Moreover, when testing the shifter, it is necessary to apply a damping force to the shift cable of the shifter to simulate the actual working condition of the shifter. At present...
