The invention discloses an automatic centering and self-locking device for a tire smoothness test bench. The automatic centering and self-locking device comprises a test bench base, a test bench vertical plate, a load loading cylinder, a linear guide rail, a tire mounting flat plate with an inclined plane and a sliding block, a locking hydraulic cylinder, a balance two-force rod, a wedge block with a sliding groove and a locking shell. The test bed base and the test bed vertical plate form a test bed main body. The load loading cylinder and the locking shell are fixed on the test bed main body. The tire mounting flat plate with the inclined surface and the sliding block is connected with the test bed main body through a linear guide rail. The two locking hydraulic cylinders are symmetrically located on the two sides of the tire mounting flat plate with the slopes and the sliding blocks and connected with the tire mounting flat plate through hinges, the two balance two-force rods on each side are connected with the locking hydraulic cylinders through one ends of the hinges, and the other ends of the two balance two-force rods are connected with the two wedge-shaped blocks with the sliding grooves. The device is simple and reasonable in structure, automatic centering can be achieved in the locking process through the balance two-force-rod structure, rapid locking of a tire aftera load is applied is achieved, and convenience and reliability are achieved.
Description
technical field [0001] The invention relates to the technical field of tire ride comfort test bench, in particular to an automatic centering self-locking device. Background technique [0002] The six-component force characteristic of the tire moving on the uneven road can be used to establish the tire ride comfort model and apply it to the simulation of the whole vehicle to carry out the matching research of the ride comfort of the tire and the whole vehicle, and then guide the tire design. The tire smoothness test bench is an important equipment for testing the six-component force characteristics of the tire when it moves on the uneven road. [0003] Under the impact of uneven road surface, keeping the center position of the test tire unchanged is an important condition for the tire ride comfort test bench. Existing tire ride comfort test benches usually approximately keep the wheel center position constant by controlling the load of the loading cylinder, resulting in inac...
