Gear shifting performance offline detecting device of manual transmission

Abstract

The invention discloses a gear shifting performance offline detecting device of a manual transmission. The device comprises X-axle, Y-axle and Z-axle linear modules; a rotating joint is added between the Y-axle linear module and the Z-axle linear module; a centering and torque measuring mechanism is fixed on a slide table of the Z-axle linear module; the rotating joint includes a stepper motor, a speed reducer, an adapting block, a support and a cross roller bearing; and the centering and torque measuring mechanism includes a stepper motor, a speed reducing structure, a first bracket, a torque sensor, an adapting block, a second bracket, a three-way force sensor, a cross roller bearing, a mandrel and a two-jaw cylinder. As the rotating joint is added between the Y-axle linear module and the Z-axle linear module, the Z-axle linear module can rotate around the Y-axle linear module to adapt the attitude variation of gear shifting rocker arm heads of manual transmissions with different model numbers; and the device has the advantages of automatic centering of a manipulator and a rocker arm, compact structure, easy assembly, integrated control and low cost.

Description

technical field [0001] The invention relates to an automobile performance testing device, in particular to a dynamic selection / shift performance automatic testing manipulator used for an off-line detection test bench of an automobile manual transmission. Background technique [0002] The main purpose of the current selection / shift test device is to realize the transmission shift operation by simulating the operation of the shift handle by human hands, and at the same time, the size of the selection / shift force can be simply measured. The above method needs to manually connect the shift cable to the shift rocker head, but in the actual off-line test, due to the large number of products and the fast cycle of product inspection, the above method cannot meet the requirements of quickly detecting the shift performance of manual transmissions. [0003] The existing six-degree-of-freedom manipulator in the market has two more degrees of freedom than the ordinary Cartesian coordinat...

Problems solved by technology

The above method needs to manually connect the shift cable to the shift rocker head, but in the actual off-line test, due to the large number of products and the fast cycle of product detection, the above method cannot meet the requirements of quickly detecting the shift performance of manual transmissions

[0003] The existing six-degree-of-freedom manipulator in the market has two more degrees of freedom than the ordinary Cartesian coordinate manipulator, so it can accurately grasp the shift rocker head and push the rocker head to the desired gear through the rotary motion of the six rotating pairs , and adapt to the position and attitude changes of the shift rocker head between different types of transmissions, but these six-degree-of-freedom manipulators are generally very expensive
