Tractor load reversing clutch device

Abstract

The invention discloses a tractor load reversing clutch device. The device mainly comprises a clutch shaft, a left input gear, a clutch hub, a clutch pressure plate, a clutch friction plate, a release spring, an antifriction block, a clutch piston, a clutch shell and a right input gear. The left input gear, the clutch hub and the clutch piston are sequentially arranged on the left half part of the clutch shaft to form a clutch F, wherein the left input gear and the clutch piston are sleeved by a clutch shaft sleeve; and the clutch hub is fixedly connected with the clutch shaft. The clutch piston, the clutch hub and the right input gear are sequentially arranged on the right half part of the clutch shaft to form a right clutch R, wherein the right input gear and the clutch piston are sleeved by the clutch shaft sleeve; and the clutch hub is fixedly connected with the clutch shaft. The device is a left clutch and a right clutch. Because pressure oil paths are differently controlled, the service life of the clutch is prolonged. Under the action of the release spring, two oblique planes of the clutch shaft and the piston are closely attached, so that the device is automatically sealed and the dragging moment of the clutch is reduced.

Description

technical field [0001] The invention belongs to the field of tractors, and relates to a tractor clutch device, in particular to a tractor load reversing clutch device. Background technique [0002] At present, in the gearboxes of high-power wheeled tractors produced in my country, the reverse gears mostly use mechanical shifting methods such as sliding gears, meshing sleeves, and synchronizers to switch the driving direction of the tractor. When the tractor changes the driving direction, it needs to disengage the clutch to cut off the engine power first, and then switch the corresponding gears, which is slow to change gears and affects the working efficiency. However, most foreign high-power wheeled tractors use load-reversing gearboxes, that is, when switching between forward and reverse gears, the gear shifting operation is performed directly without cutting off the engine power, and the shifting efficiency is high. [0003] The tractor must be equipped with a correspondi...
