Clutch integrated structure and use method thereof

Abstract

The invention provides a clutch integrated structure and a use method thereof. An input gear hub, a gear ring, a clutch, a clutch support, a piston and a power takeoff input shaft are integrated, anda working oil way and a lubricating oil way are arranged. When power is transmitted to the input gear hub from an engine, the working oil way is full of high-pressure oil, the high-pressure oil reaches a piston cavity, the piston is pushed to press the clutch, the clutch is closed, thus, the power is transmitted to the power takeoff input shaft, the power is transmitted, meanwhile, the lubricatingoil way of the clutch is opened while the clutch is closed, the lubricating oil reaches the clutch, and a friction piece is lubricated; and in a similar way, when the friction piece does not need totransmit torque, the lubricating oil way is closed while the piston returns, thus, dragging losses of the clutch are reduced, and the efficiency is improved.

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...

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
