Description
Technical Field
[0001] The utility model relates to the technical field of steering gear wear resistance detection, in particular to a vehicle steering gear wear resistance detection device. Background Art
[0002] The steering gear, also known as the steering machine or steering gear, is the most important component in the steering system. 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 rack and pinion steering gear is the most common steering gear. Its basic structure is a pair of mutually meshing pinions and racks. When the steering shaft drives the pinion to rotate, the rack moves in a straight line. The rack directly drives the tie rod to make the steering wheel turn. It has the advantages of simple structure, low cost, sensitive steering and small size. Therefore, it is widely used in automobiles. When it is necessary to test the wear resistance of the steering gear, an automobile steering gear wear resistance detection device is required.
[0003] After searching, a wear resistance detection device for automobile steering gear disclosed in publication number CN218646614U includes a movable plate, a detection platform and a fixed plate, a movable groove is provided at the upper end of the detection platform, the movable plate and the detection platform are connected by a movable mechanism, the upper end of the detection platform is fixedly connected to a support plate, a limiting cavity is provided inside the support plate, an adjusting column is provided inside the limiting cavity and passes through the support plate and is slidably connected to the passing part, a ring is fixedly connected to the upper end of the adjusting column, an installation groove is provided at the lower end of the support plate inside the detection platform, an electric push rod is fixedly connected inside the installation groove, the output end of the electric push rod is fixedly connected to the lower end of the adjusting column, and a rotating motor is fixedly connected to the surface of one side of the fixed plate.
[0004] The above-mentioned technical solution has certain beneficial effects, but in actual use, when the limit rotating drum moves through the movement of the moving plate, it resists the end of the transmission rod of the steering gear. However, when the transmission rod of the steering gear rotates, the temperature of the contact part will increase due to the action of friction. When the temperature is too high, it is easy to cause damage to the device. For this reason, we propose a wear resistance detection device for automobile steering gear. Utility Model Content
