Description
Technical field
The present invention relates to a kind of transfer case with hydraulic clutch, paver, rig, excavator etc. are mainly used in
The equipment of fluid motor-driven is converted into by oil pump, belongs to engineering machinery field.
Background technology
In the prior art, transfer case is a kind of more ripe technology, the structure of transfer case be mostly it is same or analogous,
According to different needs, the quantity of power taking mouth can have 2~5, can also have deceleration with speedup, but because power taking mouth is provided with
The power takeoffs such as the oil pump often driven, these power takeoffs must be just driven when engine starts, thus engine starts electricity
The power requirement of machine is high, particularly in plateau or cold district, because the viscosity of fluid is big, engine fail to start feelings often occurs
Condition, need to heat fluid could start engine.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, and provide a kind of simple in construction, compact, appearance and size
Small, in light weight, technical indicator is more advanced, uses reliable, convenient to install and maintain, the low transfer case with hydraulic clutch of cost.
The purpose of the present invention is completed by following technical solution, a kind of transfer case with hydraulic clutch, and it is wrapped
The transfer case housing being fixedly connected with flywheel shell of engine is included, there is the flexible sheet coupled with engine flywheel, described elasticity
Diaphragm is arranged on hydraulic clutch shell, and hydraulic clutch shell couples transfer case input shaft, institute by driving and driven friction plate
The hydraulic clutch shell stated also couples the oil pump that oil pump drive shaft is used for drive hydraulic system principle；Transfer case input shaft and input tooth
Wheel is integrated or coupled by spline, the input as transfer case；The input gear can engage with multiple output gears simultaneously,
Or engaged by idle pulley with output gear, carry out the output of more power taking mouths.
As preferred：Described hydraulic clutch shell is as clutch oil cylinder body, built with piston and piston return bullet
Spring, movable sealing structure is also provided with hydraulic clutch shell, to the sealing of clutch lubrication oil, prevent the fluid of transfer case
To flywheel shell of engine internal leakage；The manipulation valve of electric or hand operation is provided with transfer case housing, for controlling clutch
Engagement or separation, while adjust main oil pressure and lubricating oil.
Transfer case of the present invention with hydraulic clutch, engineering truck can be achieved and also can even in cold plateau area
Fast starting, enter working condition as early as possible, improve operating efficiency；It is easy to operate with simple in construction, compact, appearance and size is small,
The features such as in light weight, technical indicator is more advanced, convenient to install and maintain using reliable, and cost is low.
Brief description of the drawings
Fig. 1 is the transmission principle block diagram of the present invention.
Fig. 2 is the internal structure schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail：Shown in Fig. 1, a kind of band hydraulic clutch of the present invention
The transfer case A of device, sending and receiving motivation B, exports and connects multiple external connection oil pumps 11 afterwards before it.Specific structure is as shown in Figure 2：It is wrapped
The transfer case housing being fixedly connected with flywheel shell of engine is included, there is the flexible sheet 1 coupled with engine flywheel（Elastic plate）, institute
The flexible sheet 1 stated is arranged on hydraulic clutch shell 2, and hydraulic clutch shell 2 passes through the connection point of driving and driven friction plate 3
Dynamic case input shaft 7, described hydraulic clutch shell 2 also couples the oil pump 11 that oil pump drive shaft 6 is used for drive hydraulic system principle；Point
Dynamic case input shaft 7 is integrated with input gear 8 or coupled by spline, the input as transfer case；The input gear can be same
When engaged with multiple output gears, or engaged by idle pulley with output gear, carry out the output of more power taking mouths.
Shown in figure, described hydraulic clutch shell 2 is used as clutch oil cylinder body, built with piston 4 and piston return
Spring 5, movable sealing structure is also provided with hydraulic clutch shell 2, to the sealing of clutch lubrication oil, prevent transfer case
Fluid is to flywheel shell of engine internal leakage；The manipulation valve 13 of electric or hand operation is provided with transfer case housing 10, for controlling
The engagement or separation of clutch processed, while adjust main oil pressure and lubricating oil.
When the engine is started, due to relative slip, input between the driving and driven friction plate 3 in hydraulic clutch be present
Axle 7 does not rotate；With the starting of engine, drive oil pump drive shaft 6 drive the oil pump 11 in the hydraulic system of transfer case from point
Dynamic lower box part inlet port carries out oil suction, and to manipulating valve fuel feeding, after being transferred to main oil pressure by the pressure-reducing valve manipulated in valve, lubricating oil
Friction plate, bearing etc. are lubricated into oil leab.When needing clutch to engage, controlled clutch handle or automatically controlled open
Close, pressure oil is transported to clutch oil inlet 12 by oil pipe, promote piston 4 to move right and compress driving and driven friction plate 3,
It is rotated together, so as to be rotated with driven input shaft 7, thus make 8 dynamic input of input gear, drive the power taking of transfer case
（Output）Gear, so as to drive work operation of oil pump.When needing clutch separation, as long as controlled clutch handle or automatically controlled opening
Close, cut off the oil-feed of clutch, piston 4 is moved to the left in the presence of return spring 5, and so driving and driven friction plate 3 just divides
From being relatively rotated, input shaft 7 just inputs without power, and transfer case just do not work.
