Problems solved by technology
The third is to use magnetic powder damping loading, connect the shifter cable or hard shaft to the magnetic powder damping device, and change the load force by controlling the current of the magnetic powder damper. Compared with the first two methods, magnetic powder damping loading is programmable. It has been improved, but the disadvantage is that the magnetic powder is prone to heating and failure during the working process, the service life is not long, the loading force is not accurate, and there are problems such as hysteresis in program control.

The invention discloses a high and low temperature reliability test bench for automobile gear shifting operation, which includes a gear selection mechanism and a load simulation mechanism. The transmission shaft is moved or rotated under the action of the gear selection mechanism to realize the gear selection or gear shift of the gear shifter; the load simulation mechanism includes a cable assembly and a cable assembly The load simulation component connected at one end, the other end of the cable assembly penetrates into the high and low temperature box from the side of the high and low temperature box and is connected with the output end of the shifter; Design a better and more reasonable gear selection mechanism and load simulation mechanism, thereby changing the notch on the high and low temperature box in the prior art, so as to reduce the sealing problem that occurs when the high and low temperature box is working, so as to ensure the shifting operation of the car The high and low temperature reliability test is carried out normally, reducing the experimental error.
Description
technical field [0001] The invention belongs to the field of experimental equipment for automobile structural components, and more specifically relates to a high-low temperature reliability test bed for automobile gear shifting manipulation. Background technique [0002] The shift operating mechanism of a car is also known as a shifter and a shift assembly. The shifter is divided into manual and manual, and is installed in passenger cars, light trucks, and heavy trucks. It is used by the driver to control the speed change of the car's gearbox during driving. The shifter generally has two main functions, namely, gear selection and gear shifting. The mode of operation of gear selection and shifting is to pull the handle by hand, and the shift handle 4 connected to the handle will drive the lower ball head to rotate, thereby driving the following gear selection and shifting cable or hard shaft action. Shift handle 4 is a lever labor-saving structure, and the ball head is exact...
