Abstract
The utility model relates to car suspension fork oscillating damper hydraulic position limiting technology, in particular to a hydraulic position limiting type variable-damping oscillating damper which not only can play the role of a common oscillating damper, but also can replace an elastic limitator made of rubber in a common suspension fork. The hydraulic position limiting type variable-damping oscillating damper comprises an oscillating damper working cylinder, an oil storage cylinder sleeved outside the oscillating damper working cylinder, a main piston cooperating with the oscillating damper working cylinder as well as a compressing unloading valve and a oil inlet valve, which are arranged on a foot valve seat of the oscillating damper working cylinder. The hydraulic position limiting type variable-damping oscillating damper is characterized in that a floating piston provided with an axial through main channel for oil liquid at the middle part is arranged between the main piston and the foot valve seat; the periphery of the main channel for oil liquid of the floating piston is provided with a position limiting damping hole; a position limiting spring is arranged between the foot valve seat and the floating piston. The hydraulic position limiting type variable-damping oscillating damper replaces the elastic limitator made of rubber in the common suspension fork besides generating the normal damping action, and has better cushioning property than the rubber limitator.
Description
Technical field
The utility model relates to the spacing technology of automotive suspension damper hydraulic, particularly a kind ofly both can play common vibration damper, can replace the hydraulic locating type damping changing impact damper of the elasticity snubber that the rubber in the conventional suspension makes again.
Background technique
Usually all be provided with the elasticity snubber that rubber is made in the automotive suspension, to limit the moving stroke of excessive suspension, in order to avoid vibration damper and miscellaneous part produce rigid bump.But the energy that this elasticity snubber produces when compression almost all stores with the form of potential energy, discharges when elongation subsequently, forms significantly vibrations.There is rigid bump when on bad road, travelling, seriously increases the dynamic load of bearing system, reduce vehicle running smoothness greatly.
Summary of the invention
The purpose of this utility model is to have rigid bump for overcoming present automotive suspension on bad road, the serious dynamic load that increases bearing system, reduce the defective of vehicle running smoothness greatly, and a kind of common vibration damper that both can play a part is proposed, can replace the hydraulic locating type damping changing impact damper of the elasticity snubber that the rubber in the conventional suspension makes again.It can eliminate the rigid bump of suspension system, and the vibration energy that dissipates rapidly, improves vehicle running smoothness.
The utility model hydraulic locating type damping changing impact damper, comprise the vibration damper clutch release slave cylinder, be nested with oil storage cylinder in the vibration damper clutch release slave cylinder outside, the main piston that matches with the vibration damper clutch release slave cylinder, be arranged on the vibration damper clutch release slave cylinder foot valve seat on compression unloading valve and oiling valve, be characterized in the floating piston that its middle part has the fluid main passage of axial perforation also is set between described main piston and foot valve seat, the periphery in this floating piston fluid main passage is provided with the limit damping hole; One limit spring is set between foot valve seat and floating piston.
The working principle of the utility model hydraulic locating type damping changing impact damper is: when the vibration damper compression stroke surpasses limit spring length decision floating piston position, main piston and floating piston join, block the fluid main passage at floating piston middle part, main piston continues when descending, the major part of the fluid below the floating piston is pushed through the little damping hole on the floating piston, fraction is clamp-oned shoe cream room by the compression unloading valve on the bottom valve, resistance to compression pression is sharply increased, be created in whole clutch release slave cylinder area and the spacing pressure spacing power of product mutually, make vibration damper have the hydraulic cushion position-limiting action.The size that changes the floating piston damping hole can be regulated the size of spacing load; Change the spacing stroke of the adjustable in length vibration damper of the limit spring between foot valve seat and the floating piston.
On the limit damping hole on the described floating piston of said structure, also be provided with spacing unloading valve.Can regulate the size of spacing load by the size that changes floating piston unloading valve video disc spring pressure, play better buffer limit effect.Thereby further improve the run smoothness of automobile on abominable road surface.
The utility model is a kind of damping changing impact damper that produces position-limiting action.It except producing normal cushioning effect, the also contemporary elasticity snubber that has replaced the rubber in the conventional suspension to make.It has better damping characteristics than rubber snubber.Energy when common rubber snubber is hit is to store then as potential energy to put back to, and system's vibration energy does not reduce.And the spacing impact energy of hydraulic stop vibration damper is converted into irreversible heat energy, distributes in atmosphere, and vibration energy is significantly reduced.The agent structure of the damping changing impact damper of hydraulic stop is identical with common dual-tube shock absorber, just increases the floating piston that a cover has unloading valve and limit spring.

Embodiment
The embodiment who provides below in conjunction with accompanying drawing describes in further detail the utility model.
With reference to Fig. 1, a kind of hydraulic locating type damping changing impact damper, comprise vibration damper clutch release slave cylinder 7, be nested with oil storage cylinder 8 in vibration damper clutch release slave cylinder 7 outsides, the main piston 1 that matches with vibration damper clutch release slave cylinder 7, be arranged on vibration damper clutch release slave cylinder 7 foot valve seat 4 on compression unloading valve 5 and oiling valve 6, be characterized at described main piston 1 and 4 of foot valve seats the floating piston 2 that its middle part has the fluid main passage of axial perforation being set also, the periphery in these floating piston 2 fluid main passages is provided with limit damping hole 14; One limit spring 3 is set between foot valve seat 4 and floating piston 2.
With reference to Fig. 2, be also to be provided with spacing unloading valve 15 on the limit damping hole 14 on the described floating piston 2 in structure shown in Figure 1.Can regulate the size of spacing load by the size that changes floating piston unloading valve video disc spring pressure, play better buffer limit effect.
Among Fig. 1-2: 9 is the floating piston seal ring, and 10 is the recovery unloading valve on the main piston, and 11 is main oil sealing, and 12 is guider, and 13 is connecting ring.
