Description

Technical Field

[0001] The utility model relates to the technical field of testing platforms, in particular to a testing platform for the working life of a sliding clutch. Background Art

[0002] A slip clutch is a type of clutch used in automobiles, motorcycles, agricultural machinery and other fields. Its main function is to achieve power transmission and disconnection between the engine and the transmission system during vehicle driving. The working principle of the slip clutch is based on the contact between two rotating planes, which interact with each other through friction when rotating at different speeds. Specifically, it mainly consists of two parts: the main drive component and the driven component. The main drive component is usually connected to the engine and has a rigid gear or flywheel; the driven component is connected to the output shaft and is responsible for transmitting power to the output shaft. In normal operation, the main drive component rotates and drives the driven component to rotate. When the two speeds are the same, there is no relative sliding, and the force transmission is direct. When the driven component stops, the contact area between the main drive component and the driven component will slip. When the sensing point tests that the main drive component and the driven component slip, the main drive component automatically stops, thereby protecting the entire transmission system.

[0003] At present, the conventional clutch working life test bench in the prior art cannot perform the working life test of the sliding clutch well, and the existing clutch working life test bench lacks rapid temperature detection and rapid cooling mechanism. When the test temperature is too high during the sliding clutch test, if the cooling mechanism is not used to quickly cool it down, it is easy to cause the high-temperature sliding clutch to burn the recorder when recording the test data. Therefore, the utility model proposes a sliding clutch working life test bench to solve the shortcomings of the prior art. Utility Model Content
