Automobile pedal durability test device and control method thereof

Abstract

The invention discloses a vehicle pedal durability test device. The vehicle pedal durability test device comprises a rack, a cantilever mechanism, a pedal, a first cylinder, a first rotating shaft and a second rotating shaft, wherein one end of the cantilever mechanism is rotationally connected to the rack through the first rotating shaft, the other end of the cantilever mechanism is connected with a piston rod of the first cylinder through a hinge, and the first cylinder is connected to the top of the rack through a hinge joint mechanism; one end of the pedal is rotationally connected to the rack through the second rotating shaft, and the first rotating shaft and the second rotating shaft are coaxially arranged; when the first cylinder applies acting force to the cantilever mechanism, the other end of the cantilever mechanism applies treading force to the other end of the pedal. According to the vehicle pedal durability test device, the first rotating shaft of the cantilever mechanism and the second rotating shaft of the pedal are coaxially arranged and it is guaranteed that a force sensor is perpendicular to the pedal and treading force in the testing process is measured along the tangential line of circular motion of the pedal all the time, force measuring veracity is guaranteed, and measuring accuracy is improved.

Description

technical field [0001] The invention relates to a test device for auto parts, more specifically, to a test device for durability of an automobile pedal and a control method thereof. Background technique [0002] With the popularization of automobile products, automobiles have entered most families as daily necessities. However, automobiles, as high-speed vehicles, may cause serious damage to the measurement when there is a problem with the parts. In all auto parts, the car brake system is the guarantee of the safety performance of the car. It is not only the brake disc that plays a role in ensuring the normal function of the brake system, but also the brake system of the whole car. The most critical component in the braking system is the trigger mechanism. The so-called trigger mechanism is what we call the brake pedal, which plays a vital role in the braking process. If the brake pedal fails, the vehicle cannot Normal braking will eventually lead to accidents, so the relia...

AI Technical Summary

Problems solved by technology

The pedal of the automobile pedal durability test device is a cantilever structure, and it moves in an arc during the motion, so it cannot meet the test accuracy requirements, because the real pedaling force cannot be simulated during the arc motion, and the measurement results are not accurate. Accurate, only the pedaling force applied in the direction along the tangent of the arc is the most realistic pedaling force, therefore, only by simulating the pedaling force in the direction along the tangent of the arc, the test results can be real
