Device for testing wear resistance of tire and impact resistance of hub

Abstract

The invention discloses a device for testing the wear resistance of a tire and the impact resistance of a hub, which comprises a detection platform, wherein the upper end face of the detection platform is provided with a bracket and an installation table, the installation table is provided with a horizontal through hole, the through hole is internally provided with a first transmission shaft, theend, which is away from a buffer installation device, of the first transmission shaft is provided with a tooth missing gear, the other end of the first transmission shaft is provided with a cross-shaped bracket, and four brackets of the cross-shaped bracket are sequentially provided with an impact friction device, an inclination friction device, a pit friction device and a flat ground friction device. The device can simulate the friction received by the tire and the impact received by the hub more accurately in a complex road condition or a single road condition, and can test the wear resistance of the tire and the impact resistance of the hub more accurately.

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...

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] The traditional devices for testing the wear resistance of tires and the impact resistance of wheels can only test tires and wheels briefly, and cannot simulate the friction and impact of tires in complex road conditions in real life
