Abstract

The utility model discloses an end cap component of a shock absorber. The end cap component of the shock absorber comprises a guider and an end cap, wherein the end cap is cylindrical and hollow, at least three barbs are arranged on the end cap and are distributed in the circumferential direction of the end cap, one ends of the barbs are connected with the end cap, and the other ends of the barbs extend into the end cap along the circumferential radial direction of the end cap. A plurality of grooves are formed in the guider along the circumferential direction, and the position and the number of the grooves correspond to the position and the number of the barbs. According to the end cap component, the barbs are arranged on the end cap, are pressed into the guider and then hook the guider, so that the end cap and the guider are connected together and then are put into an oil barrel of the shock absorber, and the end cap component is convenient to detach and install. Due to the fact that when the end cap component is installed, a spring is in a compression state, and a sealing is capable of being directly installed in a sealing position. When a screw barrel is screwed, the sealing ring does not move in the radial direction, and the assembly sealing performance of the shock absorber is guaranteed.

Description

A kind of vibration damper end-cap assembly

Technical field

The utility model relates to a kind of vibration damper accessory, especially a kind of easy accessibility, the vibration damper end-cap assembly that the fitting tight performance is good.

Background technique

Existing gas-filled type adjustable shock absorber end-cap assembly is Spielpassung for the ease of dismounting end cap cylindrical and shock absorber oil tube internal diameter, owing between end cap and the guider spring is housed, need screws with an oil tube cylindrical by swivel nut during assembling and make backing plate parts such as seal ring, end cap are pressed into oil cylinder downwards; When parts such as the swivel nut of vibration damper, end cap, guider, spring, seal ring, backing plate are packed the oil tube successively into, because spring is in the state of flicking, and end cap step place is higher than oily nozzle portion, when swivel nut screws off, seal ring easily produces radial-play, cause seal ring to be sheared by oily nozzle and backing plate and be damaged, destroyed the sealability of seal ring.

The model utility content

The technical problems to be solved in the utility model provides a kind of easy accessibility, the vibration damper end-cap assembly that the fitting tight performance is good.

For solving the problems of the technologies described above, the utility model has adopted a kind of vibration damper end-cap assembly, comprise guider and end cap, described end cap is the cylindrical hollow lid, end cap is provided with at least three barbs, described barb distribution is at the end cap circumferencial direction, and described barb one end is connected with end cap, and the other end radially stretches in the end cap along the end cap circumference; Described guider along the circumferential direction is provided with a plurality of grooves, and position and the quantity of barb are corresponding on described groove and the end cap.

The quantity of described barb and groove is three, and barb and groove evenly are arranged on end cap and the guider respectively.

The beneficial effect that the utlity model has: this end-cap assembly is by arranging barb at end cap, during installation, guider is hooked after barb is pressed into guider by the groove on the guider in elder generation, and end cap and guider are linked together, the shock absorber oil tube of packing into then makes the end-cap assembly easy accessibility; Because the spring in this assembly is in compressive state, seal ring can directly be packed into and be sealed the position, and when swivel nut screwed, seal ring can not produce radial-play, thereby guarantees vibration damper fitting tight performance.

Embodiment

Shown in Fig. 1 to 4, be a kind of vibration damper end-cap assembly, comprise guider 3 and end cap 1, end cap 1 is the cylindrical hollow lid, end cap 1 is provided with at least three barbs 2, barb 2 is distributed in end cap 1 circumferencial direction, and barb 1 one ends are connected with end cap 1, and the other end radially stretches in the end cap 1 along end cap 1 circumference; Guider 3 along the circumferential direction is provided with a plurality of grooves 4, and wherein position and the quantity of barb 2 is corresponding on groove 4 and the end cap 1.

As shown in figs. 1 and 3, along the circumferential direction evenly be provided with three barbs 2 on the end cap 1, accordingly, along the circumferential direction evenly be provided with the groove 4. that three sizes are slightly larger than barb size on the guider 3

As shown in Figure 4, during this end-cap assembly assembling, earlier spring 8 is installed in the end cap 1, then guider groove 4 is aimed at end cap barb 2, with guider 3 holddown springs 8, guider 3 is pressed in the end cap 1, then with 15 ° of guider 3 rotations, this moment, the barb 2 of end cap 1 was hooked on the guider 3, so guider 3 can not flick by spring 8 with end cap 1, made guider 3 and end cap 1 be linked to be an integral body.

Shown in Figure 4 and 5, during the assembling vibration damper, can earlier parts such as guider 3, spring 8, end cap 1 be dressed up and be the integrated end cap assemblies, the shock absorber oil tube 9 of again this assembly being packed into is because this moment, spring 8 was in compressive state, end cap 1 step place is lower than 9 mouthfuls in oil tube, seal ring 7 can directly be put into the sealing position, and when swivel nut 5 screwed with oil tube 9, seal ring 7 can not produce radial-play, avoid seal ring 7 to be sheared by 9 mouthfuls in oil tube and backing plate 6 and be damaged, make the seal ring 7 can reliable sealing.

The end cap 1 of this model utility can be processed on the basis of existing end cap 10 structures, course of working is as follows: cut out in the side of existing end cap 10 three rectangular, then with rectangular in the existing end cap 10 lateral bucklings, finally form three hooks 2 at existing end cap 10, finish the processing of end cap 1.
