Tire wear resistance and wheel impact resistance test device

Abstract

The invention discloses a testing device for tire wear resistance and hub impact resistance. The testing device for the tire wear resistance and hub impact resistance comprises a testing table, a first motor and a tire fixing device, wherein a sliding table is arranged at one end of the testing table, a second rotating shaft is arranged on the sliding table, a cross bracket is arranged at one end,far away from the sliding table, of the second rotating shaft, an impact friction device, an inclined friction device, a pit friction device and a flat land friction device are arranged on the crossbracket, the impact friction device comprises a circular rotating belt I, a rolling seat I, a rolling body I and a cage I for keeping the position of the rolling body I, the rolling body I and the cage I are arranged between the circular rotating belt I and the rolling seat I, the outer surface of the circular rotating belt I is a rough surface, and impact blocks are arranged on the outer surfaceof the circular rotating belt I. The testing device for the tire wear resistance and hub impact resistance disclosed by the invention can more accurately simulate the friction suffered by a tire and impact suffered by a hub under complex road conditions or single road conditions, thereby more accurately detecting the wear resistance of the tire and the impact resistance of the hub.

Description

technical field [0001] The invention relates to the field of tire manufacturing, in particular to a test device for tire wear resistance and hub impact resistance. 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 cause cracks, which wil...

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

[0003] 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
