Description
Technical field
This utility model relates to a kind of vehicle accessory, particularly to piston rod and the body seal group of a kind of shock absorber for vehicle
Part.
Background technology
Vibroshock is that the vibration of a kind of vehicle frame with vehicle body in order to make automobile decays rapidly, improves the ride comfort of running car
Damping unit with comfortableness.Traditional vibroshock is mainly by shell and the piston rod be located in shell, axial the one of piston rod
End extends to outside shell, and this end is for connecting end, and the other end is in sliding in shell, and this end is damping end, and damping end is by shell
Space, portion implements to divide, and promotes the outside damping end to be respectively in sliding space and damping space, sliding space and damping space
It is respectively provided with pressure oil, at the damping end of piston rod, is provided with the damping hole for sliding space with damping space conducting.
Need to keep sealing between outer peripheral face and the shell of piston rod damping end, sealing ring is generally set at this, but sealing ring
Along with occurring between mobile meeting and the inwall of shell of damping end that friction, long friction then can cause sealing ring damaged, go out
Now leak, thus the pressure during displacement of piston rod there will be leakage, cause this vibroshock to use normally.
Summary of the invention
The deficiency existed for prior art, this utility model provides a kind of good airproof performance, anti-wear, simple in construction
The piston rod of shock absorber for vehicle and body seal assembly.
For achieving the above object, this utility model provides following technical scheme: the piston rod of a kind of shock absorber for vehicle with
Body seal assembly, includes the union joint being connected with piston rod, and union joint is provided with black box, it is characterised in that: described
Black box include sheathed with union joint on Plastic resilient set, the outer peripheral face of Plastic resilient set is arranged with sealing ring,
The inwall of sealing ring is provided with several locating pieces extended towards Plastic resilient set, and Plastic resilient puts to be provided with and inserts for locating piece
The locating slot connect, is provided with elastic press part bottom locating slot and between locating piece.
Use technique scheme, by arranging Plastic resilient set on union joint, then sealing ring is located at plasticity bullet
Property put, in use, Plastic resilient set has certain elastic buffer power to sealing ring, promote sealing ring and shell it
Between coefficient of friction reduce, make be extended the service life of sealing ring, the setting of elastic collision piece make sealing ring can all the time with
Keep between outer casing inner wall sealing, even and if after there is abrasion in the surface of sealing ring, due to the power that compresses of elastic collision piece, close
Stable sealing still can be kept between seal ring and outer casing inner wall.
This utility model is further arranged to: elastic press part includes the spring being located between locating slot and locating piece
Circle, the external diameter of turn respectively with locating slot bottom and locating piece conflict.
Using technique scheme, the elastic force of elastic ring will not be lost at short notice, and service life is long.
This utility model is further set to: sealing ring is relative to the end with the other end of Plastic resilient set laminating one end
It is spherical rolling seal body that face is provided with several cross sections, and sealing ring is provided with the groove installed for this rolling seal body.
Using technique scheme, can further prevent sealing ring impaired, in use, rolling seal is known from experience
Rolling be in groove with the slip of piston rod in, rolling seal body not only can be held in the sealing between outer casing inner wall, and
Coefficient of friction is little, the most easy to wear.
Below in conjunction with the accompanying drawings this utility model is further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment；
Fig. 2 is the I portion enlarged diagram of Fig. 1.
Detailed description of the invention
The piston rod of a kind of shock absorber for vehicle as shown in Figure 1 and Figure 2 and body seal assembly, include with piston rod 1 even
The union joint 2 connect, union joint 2 is provided with black box 3, and black box 3 includes sheathed and on union joint 2 Plastic resilient set
31, the outer peripheral face of Plastic resilient set 31 is arranged with sealing ring 32, the inwall of sealing ring 32 is provided with several towards plasticity bullet
Property set 31 extension locating pieces 321, Plastic resilient set 31 is provided with the locating slots 311 for locating piece 321 grafting, locating slot 311
Elastic press part 4 it is provided with between bottom and locating piece 321.In such scheme, by arranging Plastic resilient set on union joint 2
31, then sealing ring 32 is located on Plastic resilient set 31, in use, Plastic resilient set 31 has one to sealing ring 32
Fixed elastic buffer power, promotes the coefficient of friction between sealing ring 32 and shell to reduce, makes obtain the service life of sealing ring 32
Extending, the setting of elastic collision piece 4 makes sealing ring 32 can all the time and keep between outer casing inner wall sealing, though and sealing ring 32
Surface abrasion occurs after, due to the power that compresses of elastic collision piece 4, still can keep stable between sealing ring 32 and outer casing inner wall
Sealing.
In this utility model embodiment, elastic press part 4 includes to be located between locating slot 311 and locating piece 321
Turn, the external diameter of turn respectively with locating slot 311 bottom and locating piece 321 conflict.The elastic force of elastic ring will not be short
Losing in time, service life is long.
In this utility model embodiment, sealing ring 32 is relative to the end with the other end of Plastic resilient set 31 laminating one end
It is spherical rolling seal body 33 that face is provided with several cross sections, and sealing ring 32 is provided with for the installation of this rolling seal body 33
Groove 322.So arranging can further prevent sealing ring 32 impaired, and in use, rolling seal body 33 can be with piston
The slip of bar 1 and roll in being in groove 322, rolling seal body 33 not only can be held in the sealing between outer casing inner wall, and
Coefficient of friction is little, the most easy to wear.
