Description
Technical field
The utility model multi-disc hydraulic coupling belongs to engine art, particularly relates to a kind of two-wheeled motor vehicle, motor tricycle, four-wheel motor vehicle of being applied to, and is installed in the multi-disc hydraulic coupling in the engine crankcase.
Background technique
Most multi-disc wet clutch that adopt in present two-wheeled motor vehicle, motor tricycle and four-wheel motor vehicle, multi-disc wet clutch often comes transmitting torque by the frictional force that preloading spring pressure produces, but the premature wear that causes owing to reasons such as misoperations, make spring pressure descend, thereby it is big with the change of clutch stroke to skid when causing transmitting torque, and generally passing through more, renewal of facing renewal solves with the adjustment stroke.Simultaneously because different operators can make the state of wear difference, thereby reduced operating accuracy.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art part, and designs a kind of gap that wearing and tearing produce that can remedy, and keeps transmitting torque constant, makes clutch work and operates normal multi-disc hydraulic coupling.
The purpose of this utility model reaches by following measure, clutch drum, clutch plunger, unidirectional valve ball, O shape rubber seal, wavy spring, steel disc, friction plate, back-up ring, friction hub, return spring, the return spring seat, snap ring is formed, and unidirectional valve ball is installed in the clutch plunger, O shape rubber seal is installed in the groove of clutch plunger, clutch plunger is arranged on the bottom of clutch drum, and return spring is installed on the return spring seat, and snap ring is stuck on the clutch drum, wavy spring is installed in the piston area groove, steel disc and friction plate are installed on the clutch plunger, alternately are installed in the clutch drum, and the friction hub is installed in above last a slice friction plate, back-up ring snaps in the clutch drum annular groove, steel disc connects with clutch drum, and clutch assembly is contained on the axle, puts into pad, with locking nut it is fixed on the axle, pad and needle bearing are enclosed within on the axle, and the duplicate gear small end is connected with friction plate, and duplicate gear is supported on the needle bearing.During clutch work, control machine oil enters in the axle, and is full of the inner chamber of clutch plunger and clutch drum formation, unidirectional valve ball sealing under oil pressure, clutch plunger outwards moves, and is pushing away wavy spring, steel disc, friction plate and friction hub and is outwards moving, and last stop bit is in the back-up ring place.During clutch separation, release oil pressure from loop and unidirectional valve ball, under the promotion of return spring, steel disc, friction plate separate.In that unidirectional valve ball stop bit is in hydraulic coupling piston taper hole under the oil pressure effect, machine oil can not leak; When not having oil pressure, unidirectional valve ball moves upward under centrifugal action, and lubricating oil leakage goes out, and can accelerate separating rate like this, and friction plate is lubricated.Wavy spring in conjunction with the time play buffer function, prevent to send out when the hydraulic coupling friction plate from engaging with steel disc and dash.During joint, power is exported to axle to clutch drum to friction plate to steel disc by duplicate gear, and during separation, power interrupts between friction plate and steel disc.During friction disc wear, the hydraulic coupling piston can remedy the gap automatically under hydraulic pressure.
Friction plate and steel disc are multidisc.
The utility model structure uniqueness, the multidisc hydraulic coupling, be directly installed in the engine crankcase, wavy spring in conjunction with the time play buffer function, preventing that hydraulic coupling from sending out dashes, unidirectional valve ball can be accelerated to separate when separating and be lubricated, and during wearing and tearing, the hydraulic coupling piston can remedy the gap automatically under hydraulic pressure.
