Fall the distribution pipe device of description.
Detailed description of the invention
By reading the detailed description and accompanying drawings of the following non-limiting embodiment for meeting present patent application purpose and range,
Other objects, advantages and features of the present invention will be apparent from, in the accompanying drawings:
- Fig. 1 is the distribution that the fluid pressure according to the present invention being assembled in the axis with cylindrical hole is allocated
The schematic vertical sectional view of pipe device, and
- Fig. 2 is to show the longitudinal cutaway view Amplified image for the radial holding part being formed in distribution pipe, which is also schematic
, the radial direction holding part is used to receive the gasket between the distribution pipe and cylindrical hole, is equipped in the cylindrical hole
The distribution pipe.
Specific embodiment
With reference to the schematic diagram of Fig. 1 and Fig. 2, pipe (the total attached drawing mark being fixed on axis (total appended drawing reference is 20) is shown
It is denoted as 10), the pipe is for distributing two hydraulic pressures P1 and P2.As the non-limiting reality for meeting the object of the invention and range
Apply example, the pipe 10 (using XX' as axis) made of steel, steel alloy, aluminum or aluminum alloy be motor vehicles automatic gear-box or
The hydraulic distribution pipe of the hydraulic controlling type mechanical gear box of person's motor vehicles.
The arrow P of Fig. 1 shows hydraulic pressure (oil) and enters in described device.Appended drawing reference 40 indicates oil inlet, attached
Icon note 50 indicates the bearing support of transmission shaft 20.
Gasket (common reference numerals 30) is arranged between the outer wall 11 of distribution pipe 10 and the hole 21 of axis 20.
Gasket 30 is supported by the radial holding part of " groove " (common reference numerals 12) shape.The gasket 30 this
A little grooves 12 and the distribution pipe 10 " integrateds molding " and by make the distribution pipe 10 wall including the groove 12
Part molding is to implement.
As Fig. 2 figure on well show, molding tool of the cylindrical wall of pipe 10 in the region of groove 12 is there are two external diameter
To the shape of the periphery extension (being indicated respectively by appended drawing reference 13 and 14) of extension.The two extensions 13 and 14 are axially separated with
Distance " d ", and be implemented between described two extensions the substantial arc of groove 12 for receiving gasket 30
Surface 15.
The molding of principle according to the present invention, the wall of distribution pipe 10 passes through the side for being known as " hydroforming " known per se
Method is implemented.
Hydroforming is the manufacturing method manufactured by the plastic forming of the part (such as plate or pipe) of thickness weakness.Zero
The original shape of part is limited by being known as the mould of " mold ".Different from being molded, without mutual in the hydraulic forming method
The mold of the mold of benefit, the complementation is replaced by high-pressure fluid, and the high-pressure fluid forces part using the mold cavity shapes of mold.Make
With pressurized fluid, can be exerted a force to by conventional components in the region for being difficult to enter (or even can not enter).This method
Used material is very various but these materials have common main feature: the elastic range of these materials is as much as possible
It is small, to avoid the excessive elastic recovery when Fluid pressure is released.It is known that aluminium alloy, especially is used in hydroforming
Special steel alloy.
Hydraulic forming method is primarily used in aeronautics.This method is also answered in the manufacture of bicycle aluminium frame
With.Finally, known this method be used for manufacture motor vehicle construction vehicle frame or mounting type some zero made of metal plate
Part, and this method can in high volume implement complex-shaped part, while limit production cost.
Hydraulic forming method for manufacturing distribution pipe 10 can be the method for " using fixing mould ", wherein only to adding
The implementation of the pressurization of fluid is pressed to help to obtain final shape, or as modification, the hydraulic forming method can be for " use can
The method of moving mold ", wherein when molding is hydroformed the pressure activated of pressurized fluid, different mold complete it is described at
Type.
Certainly, the shape of groove 12 (can be sealed according to selected sealing technique, especially in accordance with the shape of gasket 30
Segment, ring washer, flat gasket etc.) and change.
In the new opplication, the distribution pipe 10 implemented by hydroforming, which integrated can have, receives the recessed of gasket 30
Slot 12.
The structure and the distribution pipe for the distribution pipe device being allocated above with the fluid pressure that embodiment describes
Manufacturing method have the further advantage that some of advantages are as follows:
Can to be controlled at manufacturing complex-shaped distribution pipe (this is due to through integrated seal member) originally,
Distribution pipe can be in high volume manufactured,
It can implement the distribution pipe of satisfactory mechanical property,
It can be avoided the manufacture by removal material processing (such as turning) of distribution pipe when pipe is made of metal, or
Person can be avoided the manufacture of heavy in section distribution pipe when pipe is made of plastic material,
Due to hydroforming, the distribution pipe (there is the material creep being ready for) in nearly constant section can be manufactured, and
Therefore it is substantially reduced the risk for starting to produce fracture, and last
It can simplify negative part (axis), the feminine gender part (axis) can have the lesser hole of diameter, while have in phase
To the air-tightness of longer part (such as gear-box axle) middle.
