Problems solved by technology

With the development of automobiles in the direction of high speed, safety, energy saving, and comfort, the requirements for high performance tires are also increasing year by year. The wear resistance of tires has become an important indicator for testing the quality of tires. At the same time, some roads are now in Speed ​​bumps will be set up where speed limits are required. When the car passes through the speed bumps, it will cause a large impact on the wheel hub of the tire and cause cracks, which will bring safety hazards. Therefore, after the tires are produced, it is necessary to sample the tires. Test the wear resistance of tires and the impact resistance of wheels
Traditional devices for testing tire wear resistance and wheel hub impact resistance can only simply test tires and wheel hubs, and cannot simulate the friction and impact of tires in complex road conditions in real life

Abstract

The invention discloses a device for testing wear resistance of a tire and impact resistance of a wheel hub. The device comprises a detection stand, a first motor and a tire fixing device. One end ofthe detection stand is provided with a slide stand which is provided with a second rotating shaft. One end, which is away from the slide stand, of the second rotating shaft is provided with a cross bracket. The cross bracket is provided with an impact friction device, an inclination friction device, a pit friction device and a ground friction device. The impact friction device comprises a first ring rotating belt, a first rolling base, first rollers and a first holder used for maintaining the position of the first rollers. The first rollers and the first holder are arranged between the first ring rotating belt and the first rolling base. The external surface of the first ring rotating belt is a rough surface. Impact blocks are arranged on the external surface of the first ring rotating belt. The friction of the tire and the impact to the wheel hub under the complex road condition or the single road condition can be more accurately simulated so that the wear resistance of the tire and the impact resistance of the wheel hub can be more accurately tested.

Description

technical field [0001] The invention relates to the field of tire manufacturing, in particular to a device for testing the wear resistance of tires and the impact resistance of hubs. Background technique [0002] Tires are one of the most important components of a car. Its main function is to support the entire weight of the vehicle, bear the load of the car, transmit traction and braking torque, and ensure the adhesion between the wheel and the road. Most of the tires are rubber material. With the development of automobiles in the direction of high speed, safety, energy saving, and comfort, the requirements for high performance tires are also increasing year by year. The wear resistance of tires has become an important indicator for testing the quality of tires. At the same time, some roads are now in Speed ​​bumps will be set up where the speed limit is required. When the car passes through the speed bump, it will cause a large impact on the wheel hub of the tire and caus...
