Clutch of a single engine washing and sweeping vehicle and its working method

Abstract

The invention discloses a clutch for a single engine washing and sweeping vehicle and its working method, which comprises a shaft sleeve, a pulley, a transmission plate, a pressure plate and a double-cylinder intake ring, the transmission plate and the pulley are rotatably installed on the outer circumference of the shaft sleeve, and the transmission plate It rotates synchronously with the shaft sleeve, the rear side of the pulley is provided with an inner gear, and the outer periphery of the front part of the transmission disc is provided with external teeth that can be clutched with the inner gear; the pressure plate is installed axially on the outer circumference of the transmission disc, and the pressure plate It rotates synchronously with the transmission plate. The front side of the pressure plate is provided with a friction plate that can be clutched with the rear side of the pulley. The double-cylinder intake ring is provided with a first air intake hole and a first annular cavity connected to the first air intake hole. Body, the second air inlet and the second annular cavity connected with the second air inlet, the first piston is installed in the first annular cavity for pushing the pressure plate close to the pulley, and the second annular cavity is installed in the second annular cavity for pushing The drive plate is close to the second piston of the pulley. The present invention does not limit the engagement speed and can output high torque.

Description

technical field [0001] The invention belongs to the technical field of clutches, and in particular relates to a clutch for a single engine cleaning and sweeping vehicle and a working method thereof. Background technique [0002] The pneumatic clutches currently used in single-engine sweeping vehicles are either friction clutches or meshing clutches; among them, friction clutches are large in size and small in transmission torque, while meshing clutches are large in transmission torque but cannot be combined at high speed. Two problems: 1) the clutch with high torque cannot be engaged at high speed; 2) the clutch torque that can be engaged at high speed is small. Contents of the invention [0003] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to provide a single-engine sweeping car clutch and method that does not limit the engagement speed and can output high torque. [0004] In order to solve the above-me...
