Technical Field
The invention belongs to the field of inspection robots, and particularly relates to a clutch for an inspection robot track.
Background
The clutch is typically mounted between the engine and the transmission and is the component of the drive train that is directly associated with the engine. The clutch is usually mounted with the flywheel set of the engine crankshaft and is the component that cuts off and transmits power between the engine and the drive train. The clutch is similar to a switch, and the power transmission action is engaged or disengaged, the driving part and the driven part of the clutch mechanism can be temporarily separated and can be gradually engaged, and relative rotation is possible in the transmission process. The driving part and the driven part of the clutch can not adopt rigid connection.
