Constant-pressure type wet type multi-chip transfer case clutch for tractors

Abstract

The invention relates to a constant-pressure type wet type multi-chip transfer case clutch for tractors, mainly comprising a driven shaft, a friction plate baffle plate, a driven gear, a spline hub, a driving friction plate, a driven friction plate, a pressure plate, a piston, a cylinder body, a disc-type pressure spring and a locking nut; and the left end of the driven shaft is connected with the front axle of a tractor, the friction plate baffle plate is fixedly connected on the driven shaft, and a pressure oil duct A and a lubricating oil duct B are arranged on the driven shaft. The driven gear is connected with a speed changing box of the tractor by a meshing gear pair, the spline hub is fixedly connected on the driven gear, a group of the driving friction plates and a group of the driven friction plates are respectively sheathed on the spline hub and the driven shaft sequentially in a staggering way, and the pressure plate, the piston, the cylinder body, the disc-type pressure spring and the locking nut are sequentially sheathed on the driven shaft from left to right. The transmitting and interruption of power of the transfer case of the tractor are controlled by pressure oil, so as to engage and separate the power of the front axle of the tractor at any time under the condition of no stop of the tractor, the operation is convenient and flexible and the clutch is beneficial to distribution of the whole machine.

Description

technical field [0001] The invention belongs to the field of tractors, and relates to a clutch for a tractor, in particular to an atmospheric pressure wet multi-plate transfer case clutch for a tractor. Background technique [0002] At present, on domestically produced tractors, most of the transfer cases adopt mechanical engagement and separation mechanisms, which are realized by manipulating sliding gears or meshing sleeves, and need to be stopped for manipulation. Although the cost of this kind of transfer case is low, it needs to introduce the joystick into the cab through a set of cumbersome mechanical transmission lines, and complete the joint and separation of the transfer case through the driver's control lever. The configuration components are not only difficult to arrange, but also The operating comfort is poor, and it is easy to cause difficult joints during operation, which brings a lot of inconvenience to the driver.
