Problems solved by technology

However, most of the lubricating oil circuits in the existing clutch structures are normally open, that is, when the clutch is closed and disconnected, the lubricating oil is passed through, resulting in large drag loss and low efficiency; there are also some that use solenoid valves to control the lubricating oil circuit On-off structure, but this kind of solenoid valve control leads to complex structure, and cannot guarantee complete synchronization with clutch on-off

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0031] The power take-off clutch integrated structure of the present invention controls the connection and disconnection between the engine power and the power take-off, and has a compact structure. The clutch structure integrates input gear hub, ring gear, clutch, clutch support, piston, power take-off input shaft and other parts. When the power is transmitted from the engine to the input gear hub, the working oil circuit is filled with high-pressure oil and reaches the piston cavity, pushing the piston to compress the clutch. Thereby the power is transmitted to the input gear on the input shaft of the power take-off for power transmission.

[0032] When the high-pressure oil pushes the piston to move, the lubricating oil circuit of the clutch is opened, and the lubricating oil reaches the ...

Abstract

The invention provides other usage methods of a clutch integrated structure, which integrates an input gear hub, a ring gear, a clutch, a clutch support, a piston and a power take-off input shaft, and is provided with a working oil circuit and a lubricating oil circuit; when the power is transmitted from the engine To the input gear hub, the working oil circuit is filled with high-pressure oil and reaches the piston cavity, pushing the piston to press the clutch, and the clutch is closed, so that the power is transmitted to the input shaft of the power take-off for power transmission. At the same time, when the clutch is closed, the clutch The lubricating oil circuit is opened, and the lubricating oil reaches the clutch to lubricate the friction plate; similarly, when the friction plate does not need to transmit torque, the piston returns and the lubricating oil circuit is closed, thereby reducing the drag loss of the clutch and improving efficiency.

Description

technical field [0001] The invention relates to a shifting structure, in particular to a clutch integration structure and a using method thereof. Background technique [0002] At present, domestic tractors match manual transmissions. In recent years, more advanced synchronizer shifting and power shifting products have also appeared on the market. However, the transmission axle box assembly of the power shift product is generally directly imported from abroad, and the cost is high. Mechanical-hydraulic power-split CVT products that are more advanced and complex than power shift technology have already accounted for half of the market in Europe, but tractors that match CVT are still blank in the domestic market. Synchronizer shifting products have relatively large shifting impact and short life. In comparison, the clutch shifting structure adopts a hydraulic system, which has small shifting impact and long service life. However, most of the lubricating oil circuits in the e...
