Abstract

The invention discloses an automobile gear shifting operation high-low temperature reliability test bed, which comprises a gear selecting and shifting mechanism and a load simulation mechanism, wherein the gear selecting and shifting mechanism is connected with a transmission shaft, the transmission shaft penetrates into a high-low temperature box from the side face of the high-low temperature boxand is connected with a gear shifter, and the transmission shaft moves or rotates under the action of the gear selecting and shifting mechanism to achieve gear selecting or gear shifting of the gearshifter; the load simulation mechanism comprises an inhaul cable assembly and a load simulation assembly connected with one end of the inhaul cable assembly, and the other end of the inhaul cable assembly penetrates into the high-low temperature box from the side face of the high-low temperature box and is connected with the output end of the gear shifter. The invention aims to provide the automobile gear shifting operation high-low temperature reliability test bed, by designing the gear selecting and shifting mechanism and the load simulating mechanism which are better and more reasonable, anotch formed in the high-low temperature box in the prior art is changed, so that the sealing problem of the high-low temperature box during working is reduced, normal operation of the automobile gearshifting operation high-low temperature reliability test is guaranteed, and experiment errors are reduced.

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...
