Abstract

Transmissions for heavy trucks and other heavy equipment usually have at least 8 to 25 gears which allow the driver to select the gear manually. It uses gear selector to select the gear. In a transmission test bench, the gear selector is activated by a gearshift device. The gearshift device can perform two movement to transmission: shifting movement and selecting movement. For the traditional test bench, the operator has to torque to the gearshift device manually for each transmission test position, it will affect the efficiency of the working effects and accuracy. The new gearshift device has the following features: 1. the new gearshift device can be applied to the transmission test bench which the selector and shift level are separated on transmission body. 2. The new gearshift device can achieve the shift movement and the select movement of transmission by two units: shift unit and select unit.3. The new gearshift device can perform the shifting movement and selecting movement under the control of transmission test bench controller. 4. There are force sensor and displacement sensor on the new gearshift device to get the force and displacement signal information and send to test controller. The new gearshift device for transmission test bench can not only prevent incorrect operations during manual shifting, but also can make the shifting movement of transmission more accurate, faster and easier.

Disclosure Title:
New gearshift device for transmission test bench

Abstract of Invention:
...Background:

Transmissions for heavy trucks and other heavy equipment usually have at least 8 to 25 gears which allow the driver to select the gear manually. It uses gear selector to select the gear. In a transmission test bench, the gear selector is activated by a gearshift device. The gearshift device can perform two movement to transmission: shifting movement and selecting movement.

...Statement of problem:

For the traditional test bench, the operator has to torque to the gearshift device manually for each transmission test position, it will affect the efficiency of the working effects and accuracy.

...Novel features:

 The new gearshift device has the following features:
1. The new gearshift device can be applied to the transmission test bench which the selector and shift level are separated on transmission body.

2. The new gearshift device can achieve the shift movement and the select movement of transmission by two units: shift unit and select unit.

3. The new gearshift device can perform the shifting movement and selecting movement under the control of transmission test bench controller.

4. There are force sensor and displacement sensor on the new gearshift device to get the force and displacement signal information and send to test controller.

...Business benefits:

The new gearshift device for transmission test bench can not only prevent incorrect operations during manual shifting, but also can make the shifting movement of transmission more accurate, faster and easier.

Description

The shift device of transmission test bench includes two units:...
