For realizing above-mentioned purpose; The technological scheme of the utility model is to include oil storage cylinder, be arranged on the clutch release slave cylinder in the oil storage cylinder; Said clutch release slave cylinder bottom surface is provided with a compression valve, is provided with the piston rod of an axial motion in the clutch release slave cylinder, on piston rod, is provided with piston valve; Said piston valve is divided into two chambeies up and down with clutch release slave cylinder; Be provided with seal arrangement between said piston rod and the oil storage cylinder, also include two guided bearing devices, this pair guided bearing device includes upper guide, following guider and support lantern ring; Described upper guide is fixedly installed on the upper end position in the oil storage cylinder and constitutes guiding with piston rod and cooperates; Described guider down is fixedly set in the oil storage cylinder and is arranged at intervals at the below of upper guide, and described support lantern ring is sheathed on the piston rod and is positioned at oil storage cylinder, and the axial two ends of this support lantern ring are fixedly supported upon the lower end of upper guide and the upper end of following guider respectively.
Further be provided with is between described guider down and the oil storage cylinder passage to be set.Between described upper guide and the oil storage cylinder passage is set.Through this setting, passage has the oil gas IWF, has guaranteed enough oil mass storages, has improved the good spatial condition of fluid heat radiation, the working life that has strengthened vibration damper.
Further being provided with is middle part its dual tapered setting relatively of described support lantern ring.Through this setting, can increase the space of storing fluid, make the heat radiation of vibration damper better, improve the working life of vibration damper.
The lower end that further setting is described support lantern ring is fixedly set in second seal arrangement that cooperates with rod seal.Through this setting, realize double seal, make that the sealing effect of the seal arrangement between piston rod and the oil storage cylinder is better, help to improve the operating life and the stability in use of vibration damper.
Further be provided with is the described lower end of guider down and the upper support secure fit of clutch release slave cylinder.
The utility model has the advantages that and have two guided bearing devices; Increased the bending resistance of piston rod; Can improve the stability of vehicle when turning; And vehicle when turning to the bigger lateral force of the vibration damper that passes to, thereby and improved ride comfort the working life of improving vibration damper greatly.
Below in conjunction with Figure of description and embodiment the utility model is done further introduction.
Description of drawings
Fig. 1 the utility model embodiment structural representation.
Embodiment
Through embodiment the utility model is carried out concrete description below; Only be used for the utility model is further specified; Can not be interpreted as the qualification to the utility model protection domain, the technician in this field can make some nonessential improvement and adjustment to the utility model according to the content of above-mentioned model utility.
The embodiment of the utility model as shown in Figure 1 includes oil storage cylinder 1, is arranged on the clutch release slave cylinder 2 in the oil storage cylinder 1, and said clutch release slave cylinder 2 bottom surfaces are provided with a compression valve 3; Be provided with the piston rod 4 of an axial motion in the clutch release slave cylinder 2, on piston rod 4, be provided with piston valve 5, said piston valve 5 is divided into two chambeies up and down with clutch release slave cylinder; Be provided with seal arrangement 61 between said piston rod 4 and the oil storage cylinder 1; Also include two guided bearing devices, this pair guided bearing device includes upper guide 7, following guider 8 and support lantern ring 9, and described upper guide 7 is fixedly installed on the upper end position in the oil storage cylinder 1 and constitutes guiding with piston rod 4 and cooperates; Described guider 8 down is fixedly set in the oil storage cylinder 2 and is arranged at intervals at the below of upper guide 7; This upper guide 7 of present embodiment and the identical setting of following guider 8 structures all constitute the guiding slippage with piston rod 4 and cooperate, and also can reduce the cost of offering mould again thus; Described support lantern ring 9 is sheathed on the piston rod 4 and is positioned at oil storage cylinder 1; And the axial two ends of this support lantern ring 9 are fixedly supported upon the lower end of upper guide 7 and the upper end of upper guide 7 respectively, and in the actual assembled process, the horizontal direction of this upper guide 7 and upper guide 7 carries out fixed limit by the madial wall of oil storage cylinder 1; The upper axial end of upper guide 7 is spacing by the last roof of oil storage cylinder 1; The lower end of upper guide 7 is by support lantern ring 9 fixed limits, and similarly, the described lower end of guider 8 down and the upper support of clutch release slave cylinder 2 are fixed.
