Description

Technical Field

[0001] The invention belongs to the technical field of two-wheeled vehicle chain system simulation experiment equipment, and in particular relates to a two-wheeled vehicle chain system road condition automatic simulation experiment platform. Background Art

[0002] The existing bicycle chain system simulation test bench uses the following experimental method: a bicycle is placed on a stand, which holds the rear wheel suspended in the air. A rider then rides the bicycle, pedals, and manually shifts the gears using the shifter. This manually operates the chain system, and another person squats next to the test bike to visually observe the chain system's operation and the shifting process. This simulation test bench has the following drawbacks:

[0003] 1. During the experiment, the rear wheel of the bicycle was held up by a stand. The experimenters could only simulate the posture of this bicycle, but not various riding conditions.

[0004] 2. The test bench has a simple structure and a low degree of automation. The operation requires the participation of two or more people, and the participants cannot leave the bench during the entire process. Although some of the people can observe from the side, manual observation cannot accurately record the experimental data in real time. Due to personal physical factors, cyclists may not be able to meet the test bench's testing requirements, especially the long-term riding requirements designed for the durability of the chain system. These factors lead to low efficiency of the test bench, inaccurate test results, and incomplete data.

[0005] 3. The test bench has a single function and cannot perform multiple functions or performance tests on the chain system. During the testing process, there is a lack of protection for the chain system. Summary of the Invention
