Abstract

The invention discloses a test bench for forward-direction durability of a steering gear. The test bench comprises the steering gear, a bench body and a steering shaft, wherein the steering gear is fixed at a center position of the bench body, a steering input end of the steering gear is connected with the steering shaft, the other end of the steering shaft is connected with a DC motor, the steering shaft is also connected with a torque sensor, the other end of the DC motor is connected with an angle sensor, an output end of the steering gear is connected with a tension sensor, the other end of the tension sensor is connected with a displacement sensor, and the other end of the displacement sensor is connected with a multi-frequency wave loading cylinder. The test bench of the invention has the advantages of capacity for effectively detecting various performance of the steering gear under various working condition states, and high accuracy of detection data.

Description

technical field [0001] The invention relates to the field of vehicle steering gear detection, in particular to a steering gear positive durability test bench and a testing method. Background technique [0002] Automobile steering gear, also known as steering gear and steering gear, is the most important part in the steering system of an automobile. Its function is to increase the force transmitted from the steering wheel to the steering transmission mechanism and change the direction of force transmission. The commonly used gear teeth Bar type, worm crank pin type and recirculating ball type. [0003] Automobile steering gears need to undergo various tests during production to ensure their accuracy and service life. The vehicle is used together until it is replaced due to a non-repairable failure or is scrapped together with the vehicle. The forward direction means that the steering gear input shaft receives the manipulation from the steering wheel, and the reverse directio...
