Electric-hydraulic controlled power output clutch with hydraulic brake

Abstract

The invention relates to an electric-hydraulic controlled power output clutch with a hydraulic brake, which comprises a power output clutch housing body, a coaxial seal ring, a driven hub, a driving friction plate, a driven friction plate, a baffle plate, a circlip, a brake friction plate, brake pistons, a driving hub, a screw return spring, a clutch piston and a bearing, wherein the driving hub and a shaft A of a power output clutch of a tractor form a key joint; the driven hub and a shaft B of a power output transmission case of the tractor form a key joint; the driving friction plate and the driven friction plate are installed between the driving hub and the driven hub; the screw return spring is installed between the clutch piston and the driven hub; the two brake pistons are installed at the back part of the power output clutch housing body; and the circlip is installed at the back part of the driven hub, the front part of the circlip is provided with the baffle plate, and the back part of the circlip is provided with the brake friction plate. The electric-hydraulic control on the combination, the separation and the brake hydraulic control of the power output clutch can be realized by an electromagnetic valve, thereby facilitating the control on the combination, the separation and the brake of the clutch by using a button switch in the cab.

Description

technical field [0001] The invention belongs to the field of tractors, and relates to a tractor clutch, in particular to an electro-hydraulic control power output clutch with hydraulic brake. Background technique [0002] At present, on some high-power tractors produced in China, the power output clutch is generally integrated with the main clutch, which is a double-acting clutch installed between the engine and the gearbox. When the power output clutch is disengaged, the power of the engine is cut off from the power output clutch shaft, so devices that require an uninterrupted power source such as hydraulic pumps cannot be arranged on the gearbox. High-power tractors often require multiple hydraulic pumps to meet the needs of different functions, and it is often very difficult to install them on the engine. Therefore, setting the power output clutch device at the rear of the tractor can make the power output clutch shaft of the tractor cut off the power of the power output...
