A tire test bench with stable pressure

Abstract

The invention provides a tire test bench with stable pressure, which includes a base, one end of the base is fixed with a support frame, and the other end is fixed with a booster seat; The two ends of the reinforcing beam are respectively connected to form a frame by connecting rods; one of the connecting rods is connected to the support frame through a hinge to make the reinforcing beam rotate around the hinge; the other connecting rod is connected to the reinforcing base through a screw, and the screw The bottom end of the screw rod is threadedly connected with the booster seat, and the top of the screw rod is provided with a pressure stabilizing device, and the pressure stabilizing device is located above the connecting rod to apply force to it; the middle parts of the two booster beams are each fixed with a bearing seat, through which The mounting shaft installs the tire between the two bearing seats; the base directly below the tire is fixedly provided with a roller. The spring is compressed by the screw, so that the spring stores a certain elastic potential energy during the compression process, thereby greatly reducing the fluctuation of the tire loading pressure.

Description

technical field [0001] The invention relates to a tire test stand, in particular to a tire test stand with stable pressure. Background technique [0002] In the engineering vehicle industry, most manufacturers use special tire test benches to test the hysteresis loss resistance performance of tires. However, the existing tire test benches almost all use hydraulic loading methods to ensure that tires can withstand relatively stable pressure at all times. However, hydraulic loading has disadvantages such as complex system and high cost. At present, in order to change the status quo of the hydraulic loading of the tire test bench, a screw method is used to load it, thereby reducing the cost and simplifying the system structure. However, during the tire test process, due to wear on the tire surface, the diameter of the tire will gradually become smaller, and when the tire diameter becomes smaller, the screw loading will have large fluctuations or even the loading will disappear...
