The invention discloses a single-
clutch integrated structure. The single-
clutch structure integrates an input shaft, a
clutch support, a
piston, a friction piece set, a dual piece set, a gear toothedwheel and other parts. When power is transmitted to the clutch support from the input shaft, a work oil path is full of high-pressure oil, the high-pressure oil arrives at a
piston cavity, the pistonis pushed to compress a clutch, therefore, the power is transmitted to the gear toothed wheel,
power transmission is carried out, the structure can ensure normal switching between different gears, andthe structure is compact. When the high-pressure oil pushes the
piston to move, meanwhile, a lubricating oil path of the clutch is opened, the lubricating oil arrives at the clutch, the friction piece set is lubricated, the lubricating oil path is controlled by the work oil path, control is ensured through design of a mechanical structure, and a hydraulic
system is simple in structure. Similarly,when the friction piece set does not need to transmit torque, the piston returns, meanwhile, the lubricating oil path is closed, dragging losses of the clutch are reduced, and efficiency is improved.
