Abstract

The invention relates to the technical field of agricultural machines, in particular to a wet clutch power output device and a tractor. The wet clutch power output device comprises a clutch hub, a middle hub, a first piston, a pressing disc, a clutch assembly and a brake assembly; hydraulic oil enters a piston cavity through an oil inlet hole, the first piston is pushed to extrude the clutch assembly, a clutch is engaged, a power input shaft drives the clutch hub to jointly rotate synchronously through the clutch assembly, and when the hydraulic oil is drained, the first piston is reset, at the moment, the first piston does not extrude the clutch assembly, and the clutch is disengaged; when the clutch is disengaged, the hydraulic oil pushes the second piston to extrude the brake assembly, the clutch hub is braked, brake of the power output system can be achieved, the phenomenon that after the clutch is disengaged, the power output shaft continuously rotates under the inertia effect is avoided, accident risks are reduced, and safety is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a wet clutch power output device and a tractor. Background technique [0002] In the traditional wet clutch power output device, when the clutch is engaged, high-pressure liquid is injected into the oil chamber to push the piston to move, squeeze the intermediate disc and the friction plate, so as to achieve the purpose of torque transmission. However, there are two disadvantages in this structure: 1. When the clutch is separated, the oil pressure in the oil chamber is high and the oil discharge is difficult, and separation block or even non-separation is easy to occur. 2. After the clutch is disengaged, the relevant components will still continue to rotate under the action of inertia. Contents of the invention [0003] (1) The technical problem to be solved by the present invention is: when the traditional wet clutch power output device is separated, the oil pr...
