Description

But a kind of workover rig motor-car rear shock absorber

Technical field: the utility model belongs to motor vehicle fittings, particularly relates to a kind of car, rear shock absorber of motorcycle.

Background technology: the structure of existing car, rear shock absorber of motorcycle is that past inboard bevelling seals formation for 90 ° at another 1.5mm place, open end top after at one end assembling damping valve seat, inner cylinder tube, orienting sleeve, hydraulic oil successively in the osed top cylinder barrel, subtracting hydraulic damping parts such as core, oil sealing.The bumper of this structure is by disposable.Because the cylinder barrel opening of bumper is shut,, therefore whole bumper can only be scrapped and abandon in case the damage of components in the cylinder barrel is difficult to the dismounting maintenance.

Technology contents: but the purpose of this utility model provides a kind of workover rig motor-car rear shock absorber that can be for convenience detach.

In order to realize the foregoing invention purpose, the technical solution adopted in the utility model is: the open end of motor vehicle damper cylinder barrel includes oil sealing, is provided with positioning element in the oil sealing outside, adopts the detouchable movable connection method between this positioning element and the cylinder barrel.The detouchable movable connection method that adopts between described positioning element and the cylinder barrel can be threaded, pin is connected, jump ring connects, other common movable connection methods such as adding the jump ring connection is threaded.Cylinder barrel open end of the present utility model both can play the effect of parts in the cylinder barrel of location because the bevelling that has adopted movable positioning element to replace existing bumper seals, and positioning element can be opened the parts in the dismounting cylinder barrel again, convenient for maintaining.

The utility model in use, if damaging appears in the parts in the cylinder barrel, only need the positioning element of cylinder barrel open end is disassembled, just the parts in the cylinder barrel can be carried out change and repair, make bumper can continue to use, solved the problem that in the past vibration damper assembly can only be scrapped.The utility model has not only solved the problem of bumper maintenance preferably, also can be the self-propelled vehicle user and saves many expenses.Below in conjunction with accompanying drawing the technical solution of the utility model is described.

Fig. 3 is a structural representation of the present utility model.

Fig. 4 is the view of setscrew nut among Fig. 3.

Fig. 5 is the view of jump ring catch among Fig. 3.

Fig. 6, Fig. 7, Fig. 8 are respectively the local structure scheme drawings of other form of the utility model.

The specific embodiment: the location that as seen has bumper cylinder barrel 4 inner bodies from Fig. 1, Fig. 2 now is to seal 1 pad 2 that blocks oil sealing 3 outsides by the bevelling on cylinder barrel 4 open ends to realize.This locate mode is fixed, and is inconvenient to dismantle the parts in the cylinder barrel 4.And the locate mode of the utility model employing activity solves the problem of the parts in the cylinder barrel 4 for convenience detach.Its structure is seen Fig. 3.The open end of the utility model cylinder barrel 4 has oil sealing 3, adopt positioning element and cylinder barrel 4 to flexibly connect in the oil sealing outside, this positioning element is made up of setscrew nut 6 and jump ring catch 5, setscrew nut 6 is to be threaded with cylinder barrel 4, setscrew nut 6 is tightened in earlier on the cylinder barrel 4 in oil sealing 3 outsides, again jump ring catch 5 is stuck in the square groove on the cylinder barrel 4.In case damaging appears in the parts in the bumper cylinder barrel 4, jump ring catch 5 and setscrew nut 6 just need only be removed and can change.Fig. 4 is a setscrew nut, and removal hole 7 is arranged on the setscrew nut, is stuck in the hole 7 with instrument and just setscrew nut 6 can be tightened or unscrew.Jump ring catch 5 is seen Fig. 5.

Flexible connection between positioning element of the present utility model and the cylinder barrel can also be adopted alternate manner, only blocks pad 2 with jump ring catch 5 as shown in Figure 6; And for example shown in Figure 7 with setscrew nut 6; Can also use pin 8 setting up pieces 2 (see figure 8)s.

Claims (2)

1, but a kind of open end at cylinder barrel includes oil sealed workover rig motor-car rear shock absorber, it is characterized in that being provided with positioning element in the oil sealing outside, adopts the detouchable movable connection method between this positioning element and the cylinder barrel.

But 2, workover rig motor-car rear shock absorber according to claim 1, it is characterized in that the detouchable movable connection method that adopts between positioning element and the cylinder barrel can be threaded, pin is connected, jump ring connects, being threaded adds jump ring and connect.
