Description
Technical field
The present invention relates to automobile chassis damping technology, and in particular to a kind of vehicle shock absorber.
Background technology
At work, high-pressure oil flow sprays damper in the gap between plane bearing and piston rod at present, directly rushes
Shock absorber packing gland is hit, as shown in Figure 3.And since the hardware and software platform of damper designs more and more more, same oil sealing and guider knot
Structure can bear larger range of pressure change, therefore may be due to the increase of oil stream impact force in some vehicles of hardware and software platform
And shorten the oil sealing service life, cause damper leakage.Part damper, by the plane bearing of guider increase oil scraper ring come
Alleviate the impact of high-pressure oil flow, although such a structure can reduce impact force of the oil stream to oil sealing to a certain extent, work as vibration damping
During device internal pressure increase, the impact force of oil stream can also be improved and improved with pressure, and oil scraper ring is difficult to play expected alleviate to make
With, thus can not fundamentally solve the problems, such as this.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, there is provided is capable of providing and effectively improves shock resistance energy
Power, solves the problems, such as that high-pressure oil flow impacts oil sealing, improves the vehicle shock absorber of oil sealing service life.
To achieve these goals, the technical solution adopted in the utility model is：
This kind of vehicle shock absorber, including piston rod, the upper cover of piston rod are equipped with plane bearing and guider, the guiding
One end of device is located at the outside of the plane bearing, and shock absorber packing gland is arranged on the inner side of the other end of the guider；It is described to lead
The sealing ring being sleeved on the piston rod is equipped with into device, the sealing ring is located at the surface of the plane bearing, described
The conical surface set by sealing ring top and the guider inner wall is in contact.
The guider inner wall is equipped with the mounting groove being made of plane and the conical surface；The sealing ring is arranged on the mounting groove
It is interior.
Sealing ring bottom end face is located above the plane, and sealing ring top side wall and the conical surface connect
Touch.
The sealing ring is rubber seal.
The utility model has the advantage of：This kind of vehicle shock absorber, by increasing a sealing ring above plane bearing,
The mating surface of sealing ring and guider is inclined-plane.When damper internal oil pressure raises, sealing ring will produce radial deformation, make
It is even closer to obtain the cooperation of sealing ring and guider, good sealing function is produced, so as to reduce high pressure to shock absorber packing gland
Impact force, after solving high-voltage oil liquid by the gap between plane bearing and piston rod, the problem of Oil shocking shock absorber packing gland,
Effectively extend the service life of oil sealing.

Embodiment
Below against attached drawing, by the description to optimum embodiment, specific embodiment of the present utility model is made into one
Step detailed description.
As shown in Figures 1 and 2, this kind of vehicle shock absorber, including piston rod 1, are set with 2 He of plane bearing on piston rod 1
Guider 3, one end of guider 3 are located at the outside of plane bearing 2, and shock absorber packing gland 5 is arranged on the interior of the other end of guider 3
Side；The sealing ring 4 being sleeved on piston rod 1 is equipped with guider 3, sealing ring 4 is located at the surface of plane bearing 2, sealing ring 4
The conical surface set by 3 inner wall of top and guider is in contact.Sealing ring 4 is rubber seal, has good elastic performance, stress production
Change shape.
Increase a sealing ring 4 in the top of plane bearing 2.When damper is in stretching travel, working cylinder epicoele work
Make pressure increase, high-voltage oil liquid is flowed by the gap between plane bearing 2 and piston rod 1 to the installation site of sealing ring 4.When
When high-voltage oil liquid reaches 4 installation site of sealing ring, high-voltage oil liquid will promote sealing ring 4 to move upwards, due to sealing ring 4 and lead
It is contact of incline plane to the conical surface of device 3, radial space diminishes when sealing ring 4 up moves, while bullet can occur during the compression of sealing ring 4
Property deformation, the gap between sealing ring 4 and piston rod 1 and guider 3 will reduce with the increase of pressure, therefore oil liquid pressure is got over
Greatly, the sealing effect of sealing ring 4 is stronger.So as to reduce impact force of the high pressure to shock absorber packing gland 5, solution high-voltage oil liquid passes through flat
Behind gap between spherical bearing 2 and piston rod 1, the problem of Oil shocking shock absorber packing gland 5, effectively extend the service life of oil sealing.
3 inner wall of guider is equipped with the mounting groove 6 being made of plane and the conical surface；Sealing ring 4 is arranged in mounting groove 6.Mounting groove 6
For the whole coil structures on guider 3, the structure design of the conical surface on mounting groove 6 so that sealing ring 4 and guider 3 are oblique
Face contacts, and realizes the reliable installation of sealing ring 4.
4 bottom end face of sealing ring is located above plane, and 4 top side wall of sealing ring and the conical surface are in contact.When high-voltage oil liquid arrives
Up to sealing ring 4 mounting groove 6 when, high-voltage oil liquid pushes up sealing ring 4 from plan-position and moves upwards, high-voltage oil liquid effect
Under, the taper-face contact of sealing ring 4 and guider 3 is closer, plays the role of good resistance Oil shocking.
When damper low-speed motion, the operating pressure of working cylinder epicoele is relatively low.Therefore sealing ring 4 is subject to the pressure of fluid
Also smaller, the sealing effect of sealing ring 4 also can accordingly weaken, and the enclasping force between sealing ring 4 and piston rod 1 can also reduce, so that
Improve the service life of sealing ring 4.And a small amount of fluid is had at this time the top of guider 3, this part oil are reached by sealing ring 4
Liquid can play the function of lubrication sealing ring 4 and piston rod 1, so as to also reduce because sealing ring 4 is held tightly caused by piston rod 1
The problem of damper frictional force, rubber seal disclosure satisfy that durability, the service life length of sealing ring 4.
Obvious the utility model specific implementation is not subject to the restrictions described above, as long as employing the methodology of the present invention
The improvement of the various unsubstantialities carried out with technical solution, within protection scope of the present invention.
