Abstract
The utility model discloses an improved automobile shock absorber. The improved automobile shock absorber comprises a shell, wherein a dust cap is arranged at the upper end of the shell, and an oil cylinder is arranged in the shell. A piston rod and a piston valve connected with the bottom of the piston rod are arranged in the oil cylinder. A guide holder is installed at the upper end of the oil cylinder. A bottom valve is arranged on the bottom of the oil cylinder. The piston rod is provided with a non-return ring which is located between a piston valve and the guide holder. A spring is sleeved on the piston rod. One end of the spring is abutted against the guide holder. The other end of the spring is abutted against the non-return ring. In the improved automobile shock absorber, the non-return ring and the guide holder do not directly contact, a buffer spring separates the non-return ring and the guide holder, so that the non-return ring and the guide holder do not directly contact in the moving process of the piston rod, the possibility that abnormal sound is generated due to collision of the non-return ring and the guide holder is removed, meanwhile, due to the fact that high-pressure gas is contained in the improved automobile shock absorber, in the shell, part of the piston rod is pressed to compress the buffer spring, therefore, no gap exists between the non-return ring and the buffer compressed spring, the possibility that abnormal sound is generated between the non-return ring and the compressed buffer spring is removed, and comfortableness of driving an automobile is improved.
Description
Technical field
The utility model relates to the vibration damper field, particularly a kind of improved automobile absorber.
Background technique
Vehicle shock absorber is a vibration damper, and vibration damper not only is used in automobile in the suspension, in other position application is arranged also.For example be used for operator cabin, vehicle seat, steering wheel etc., also can be used as buffer is used on the vehicle bumper, existing automobile is with there not being damping spring in the vibration damper, check ring in use takes place and contacts the phenomenon that produces abnormal sound with guide holder in vibration damper easily, thereby driver's driving comfort is exerted an influence.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of automobile absorber that touches of stopping to produce between check ring and guide holder.
The utility model for the technological scheme that solves its technical problem and adopt is: a kind of improved automobile absorber, comprise housing, described housing upper end is provided with dust cover, be provided with oil cylinder in the housing, piston rod and the piston valve that is connected the piston rod bottom are installed in the described oil cylinder, the oil cylinder upper end is equipped with guide holder, the oil cylinder bottom is equipped with bottom valve, described piston rod is provided with check ring between piston valve and guide holder, described upper cover of piston rod is established a spring, one end of described spring pushes against in guide holder, another but push against in check ring.
The beneficial effects of the utility model are: directly do not contact between check ring and guide holder in the vibration damper but damping spring at interval, vibration damper check ring in the piston rod movement process can not directly be contacted with guide holder, thereby stopped to produce between them the possibility that abnormal sound takes place in collision, meanwhile because vibration damper includes pressurized gas, in the enclosure piston rod is extruded part and make the damping spring compression, there is not the gap between check ring and compression spring so yet, the possibility of abnormal sound can not take place to produce between them yet, improves the comfort level of automobile running.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not constitute the restriction to the utility model protection domain.
Fig. 1 has shown a kind of mode of execution of a kind of improved automobile absorber of the utility model, comprise housing 1, described housing 1 upper end is provided with dust cover 2, be provided with oil cylinder 3 in the housing 1, piston rod 4 and the piston valve 5 that is connected the piston rod bottom are installed in the described oil cylinder 3, oil cylinder 3 upper ends are equipped with guide holder 6, oil cylinder 3 bottoms are equipped with bottom valve 7, described piston rod 4 is provided with check ring 8 between piston valve 5 and guide holder 6, a sheathed spring 9 on the described piston rod 4, one end of described spring 9 pushes against in guide holder 6, another but push against in check ring 8, the spring 9 of buffering usefulness makes not have between them in 6 buffer functions of check ring 8 and guide holder and directly contacts, the generation that has no abnormal sound, thereby the travelling comfort of raising automobile running.
