Description

Technical Field

[0001] The invention relates to the field of automobile accelerator pedal testing, in particular to an automobile accelerator pedal durability testing device. Background Art

[0002] The Electronic Accelerator Pedal, also known as the electronic accelerator pedal, is a key component used in modern cars to control the power output of the engine or motor. Its working principle is based on the "Throttle-by-wire" technology, which transmits the driver's acceleration intention through electronic signals rather than traditional mechanical linkages.

[0003] To ensure that the accelerator pedal can work properly after millions of times of pedaling during its service life, the accelerator pedal needs to undergo rigorous testing after production, among which durability testing is the most important test. Most of the current automobile accelerator pedal durability testing equipment uses a motor to swing left and right or a cylinder to move linearly to simulate the driver's pedaling and operating reflexes, which is relatively troublesome, has a high cost, and has low testing efficiency. To this end, we propose an automobile accelerator pedal durability testing equipment to solve the above problems. Summary of the invention
