It is provided with hydraulic fluid flow rate limits device on the upper position between counter balance pocket oil outlet and friction disc support oil outlet；It is described
The central part in input shaft is arranged in secondary asphalt channel, be provided on the end face of the input shaft outer end time asphalt channel oil inlet and
Secondary asphalt channel oil inlet is connected with time asphalt channel, and the second needle bearing oil outlet is provided on the secondary asphalt channel,
Second needle bearing oil outlet is connected with the needle bearing region in clutch.
The hydraulic fluid flow rate limits device is current limiter.It is a series of high that current limiter is generally external screw-thread, interior design
The small structure of precision.
It is not attached to lead between counter balance pocket in clutch and friction disc support region, the balance plate in the clutch
On be provided with protrusion part, the protrusion part on the balance plate places with friction disc support dislocation and forms friction disc support oil inlet
Channel, on the friction disc support setting have dislocation oilhole.During actual fabrication, to meet counter balance pocket in clutch and rub
Pad holder is not attached to lead between region, generally can be by balanced pad design at closed slab construction.
The cooling and lubricating system for clutch in hybrid power gearbox of the utility model, have it is following a little：
1, simple in structure, it devises primary and secondary asphalt channel and primary and secondary asphalt channel separates, facilitate oil duct to be laid out, that is, ensure
Fuel feeding it is abundant so that clutch cooling and lubricating is more abundant, extends clutch service life, reduces clutch power damage
Consumption, while ensure that the feasibility of processing；
2, liquid is set on the position on main oil channel channel between counter balance pocket oil outlet and friction disc support oil outlet
Pressure oil flow rate limiting device such as current limiter can more accurately control the hydraulic-oil quantity for feeding friction plate assembly, from structure source
Solve the problems, such as that clutch cooling and lubricating is insufficient or excessively more than needed on head；It can be configured not according to the controlled load case demand of matching vehicle
With the current limiter in aperture, to reach the effect that can meet cooling and lubricating requirement and energy waste, become for hybrid power
The hardware and software platform of fast case, industrialization, high efficiency provide solid technical support；
3, the protrusion part on the balance plate in clutch and friction disc support dislocation place and form friction disc support oil inlet
The cooperation of dislocation oilhole on channel, friction disc support, the centrifugal force generated by the high-speed motion of input shaft itself is by hydraulic pressure
The friction disc support that oil equably throws away to friction disc support oil outlet and formed with friction disc support through balance plate protrusion part
Oil inlet passage is evenly distributed to the maximum extent at the dislocation oilhole of friction disc support, can accurately be evenly directed to hydraulic oil to rub
Pad component；
4, it is designed to be not attached to lead between the counter balance pocket in clutch and friction disc support region, in the work of clutch
Compression balance cavity space, makes the hydraulic oil of counter balance pocket discharge and is incorporated to flow direction into main oil channel channel while plug is moved to the left
In the hydraulic oil of friction disc support oil outlet, optimization counter balance pocket goes oil circuit footpath so that the cooling hydraulic oil of friction plate assembly is at this
Significantly increased during a, to take away the heat generated in clutch cohesive process.
