A double-station tire durability testing machine

Abstract

The invention discloses a double-station tire durability testing machine, which comprises a frame. The inside of the frame is divided into double-station settings, and one end of each station is provided with a mounting seat, and one side of the mounting seat is hinged with a Tire frame, one end of the bottom of the tire frame is rotatably connected with an electric bicycle tire, a connection plate is rotatably connected between the tire frame and the mounting seat, and a hydraulic cylinder is connected between the bottom of one of the connection plates and the inner bottom wall of the frame , the bottom of the tire of the electric bicycle is provided with a tire testing device; the tire testing device includes a test frame. In the present invention, the cement road test roll, the gravel road test roll and the soil road test roll are arranged on the surface of the same triangular turntable, so that the three test rolls of the cement road test roll, the gravel road test roll and the soil road test roll can be switched back and forth, and the operation is simple , saving costs, and it is easier to simulate rural or mountainous road conditions, and the test data is more accurate.

Description

technical field [0001] The invention belongs to the technical field of tire testing equipment, in particular to a double-station tire durability testing machine. Background technique [0002] As the world's will to advocate health and environmental protection continues to increase in recent years, electric bicycles are popular in the market for their advantages of convenience, energy saving and environmental protection. China's electric vehicle industry has maintained rapid growth for more than 10 years. In 2012, the annual production and sales volume reached 35.05 million vehicles. By October 2013, the number of electric vehicles in China will exceed 200 million; [0003] Electric bicycle tires are the key components of electric bicycles, and the quality of tires is directly related to the performance of electric bicycles. The durability test of electric bicycle tires can verify the rationality of tire structure and formula, provide test data for tire design, and shorten t...

AI Technical Summary

Problems solved by technology

[0005] However, (1) Electric vehicles are generally used more in rural areas and mountainous areas. In rural areas and mountainous areas, the roads are generally cement roads, gravel roads and dirt roads. When electric bicycles are in normal use, they often pass cement roads, gravel roads The road and dirt road are worn back and forth, so the data cannot be used as a normal reference for normal wear tests; (2) At present, although the test rollers of three road conditions can be used for durability tests on electric bicycle tires, the durability tests need to be replaced back and forth Equipment or test rolls, resulting in complex internal structure of the equipment, increased volume, and increased costs
