Description
Technical field
The present invention relates to metal bellows, suitable for a plurality of types of automobile fluid power deceleration devices.
Background technology
Automobile brake pattern currently on the market mainly blocks brake disc using brake block and slows down, in long downhill path
Section frequently influences braking effect using after braking system since brake block and brake disc generate heat, and easily causes accident.To improve this
Class phenomenon, automobile vendor have developed automobile fluid power deceleration device, it is a kind of auxiliary brake of vehicle, by huge used of vehicle
Performance amount is converted to thermal energy by liquid resistance, then is dissipated after being absorbed by radiator, so as to reach the mesh that vehicle is slow, slows down
's.In the control system of fluid power deceleration device, it receives and bears the pressure from system metal bellows, is converted into displacement
Output finally plays the effect of control fluid power deceleration device start and stop.
Invention content
The technical problems to be solved by the invention are just to provide a kind of with highly sensitive, the long life automobile fluid power
Retarder metal bellows meets the requirement of automobile fluid power deceleration device.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：A kind of Vehicle Hydraulic Retarder metal wave
Line pipe by seamless tube blank or has weld seam pipe to be made through hydro-forming, have 8-12 structure size unanimously annular corrugated and
Both ends are straight wall end interfaces, and the specific size of the metal bellows is defined to：
The size range of outside diameter of bel D is limited to 13.80-15mm；
The size range of inside diameter of bel d is limited to 8.70-9.60mm；
The size range of ripple interface tube internal diameter d1 is limited to 10.0-12.2mm；
The size range of bellows pitch of waves t is limited to 1.30-1.60mm；
The size range of bellows thickness of convolution a is limited to 0.84-1.20mm；
The size range of bellows interface length L1 is limited to 1.70-2.30mm；
The size range of bellows effective length L0 is limited to 11.70-13.0mm；
The size range of bellows total length L is limited to 15.70-17.0mm；
The size range of bellows wall thickness h0 is limited to 0.08-0.11mm；
And it is limited to 5-10N/mm according to the rigidity value of bellows that above-mentioned restriction size range is obtained.
The present invention defines the specific size of metal bellows one specific numberical range, and comprehensive each numerical value is together
The metal bellows obtained has many advantages, such as that high sensitivity, compression resistance are big, work shift is long, service life is long；In 1.5MPa
Under interior pressure working condition, compress 1.6mm impulse strokes from initial position and carry out perseveration by this condition, service life is reachable
5000000 times or more, and the bellows still has very high sensitivity after test, can meet operating condition requirement.
Description of the drawings
The invention will be further described with reference to the accompanying drawings and detailed description：

Specific embodiment
A kind of Vehicle Hydraulic Retarder metal bellows by seamless tube blank or has weld seam pipe to be made through hydro-forming,
With consistent annular corrugated of 8-12 structure size, corrugated shape belongs to S types, and both ends are straight wall end interfaces, each straight wall termination
Mouthful with it is annular corrugated between be continuously connected.
Refering to what is shown in Fig. 1, the item dimensions of the bellows are expressed as：
Annular corrugated outer diameter is outside diameter of bel D.
The a diameter of inside diameter of bel d in annular corrugated inner end.
The straight wall end internal diameter at both ends is the interface internal diameter d1 of bellows.
The distance between two adjacent annular corrugated outer ends or inner end are bellows pitch of waves t.
Annular corrugated outer end thickness is bellows thickness of convolution a.
The length at the straight wall end at both ends is the interface length L1 of bellows.
Axial distance between two end faces of all annular corrugated compositions together is effective length L0.
Axial distance between the end face at two straight wall ends is total length L.
The particular wall thickness for manufacturing the seamless tube blank of the bellows or having weld seam pipe is bellows wall thickness h0.
In the present embodiment, to be fully achieved, high sensitivity, compression resistance are big, work shift is long, the product of service life length
It can require, particularly the parameters of the metal bellows be made defined below：
The size range of outside diameter of bel D is limited to 13.80-15mm；
The size range of inside diameter of bel d is limited to 8.70-9.60mm；
