Abstract
The utility model discloses a single-cylinder double-way cylinder type hydraulic damping device, composed of a cylinder body, a piston, a piston rod, a sealing member, hydraulic oil, etc. The utility model has the advantages of single-cylinder double-way damping, favorable damping effect, simple structure and low cost. The utility model overcomes the defects of complicated structure existing in prior double-way cylinder type damping device and one-way damping existing in one-way cylinder type damping device. The utility model is mainly suitable for various vehicles and building facilities.
Description
The utility model relates to a kind of hydraulic damper, refers in particular to a kind of single-cylinder bidirectional hydraulic damper.
At present, the two-way telescopic shock absorber that generally uses on various automobiles, motorcycle, locomotive, the vehicle, all adopting double-deck oil cylinder is clutch release slave cylinder and oil storage cylinder, the bidirectional damper of this vibration damper is identical, damping effect is good, but its complex structure, component are more, difficulty of processing is big, materials are many, cost is high.Also use unidirectional telescopic shock absorber on the automobile that has in addition, the motor-car, i.e. the unidirectional vibration damper of single cylinder, this vibration damper structure is fairly simple, and cost is lower, but it can only unidirectional damping, can not satisfy two-way damping requirement.
The purpose of this utility model is to provide a kind of single cylinder simple in structure, the identical good damping effect of bidirectional damper two-way cylinder type hydraulic vibration damper.
In order to achieve the above object, the utility model has adopted such structure, and the two-way cylinder type hydraulic vibration damper of a kind of single cylinder mainly is made up of cylinder body, piston, piston rod, Sealing, hydraulic oil and link; Both sides at piston are respectively arranged with piston rod, have throttle orifice on the piston, and the cylinder body two ends are fitted with identical end cap, and end cap is provided with the through hole that matches with piston rod.
The utility model also adopts the end at cylinder body to be fixed with adapter sleeve, and adapter sleeve links to each other with link respectively with the piston rod of the cylinder body the other end, and link is a spherical hinge.
The utility model also adopts between end cap and the piston rod and is provided with y-type seal ring; Be provided with the O RunddichtringO between end cap and the cylinder body.
Owing to adopted said structure, its both sides Volume Changes is identical when guaranteeing piston motion by the double-faced piston bar, thereby can cancel compensating cylinder, be designed to single-layer oil cylinder, guarantee the two-way damping that provides on the one hand, improved damping effect, simplify structure on the other hand, reduced cost.
Below in conjunction with embodiment the utility model is described in further detail.
Fig. 1 is the utility model structural representation
The utility model shown in Figure 1 is mainly by cylinder body 5, piston 7, piston rod 2, link 1, Sealing and hydraulic oil are formed, piston 7 both sides are respectively arranged with piston rod 2, have the throttle orifice 10 of 4-8 millimeters of two diameters on the piston 7, the resistance of vibration damper depends primarily on the size of throttle orifice 10 diameters, the sealing that piston ring 6 improves piston 7 is housed on the piston 7, identical end cap 8 is equipped with at cylinder body 5 two ends, end cap 8 is provided with the through hole that matches with piston rod 2, adopt between end cap 8 and the piston rod 2 and adopt O type rubber seal 9 between dual polyurethane y-type seal ring 4 and end cap 8 and the cylinder barrel 5, prevent that cylinder body 5 inner fluids from flowing out and dust enters in the cylinder barrel, sealing effect is good.One end of cylinder body 5 is fixed with adapter sleeve 3, and adapter sleeve 3 links to each other with the piston rod 2 difference links 1 of cylinder body 5 the other ends.Link 1 is made up of connecting plate, universal spherical joint.When tie point generation direction in vibration damper two ends is offset, can guarantee the vibration damper proper functioning.
