Description
Technical field
The present invention relates to a kind of MacPherson types to hang hydro-pneumatic spring；It is living more particularly to a kind of limitation MacPherson type hydro-pneumatic spring
The structure of stopper rod rotary motion belongs to hydro-pneumatic spring field.
Background technique
The forward mounting of common car is generally MacPherson type suspension, as shown in figure 5, MacPherson type suspension is current most popular
One of independent suspension.The primary structure of MacPherson type suspension is to be made of helical spring plus damper, and damper can be with
The phenomenon that deviating when avoiding helical spring stress to front, rear, left and right, limited spring can only do the vibration of up and down direction, and can be with
With the stroke length of damper and the elastic soft or hard and performance to set suspension.MacPherson type is suspended on the table on road-ability
Existing satisfactory, structural volume is little, can effectively expand interior passenger space.
When vehicle oleo-pneumatic suspension uses such suspension type, since it cannot limit the rotation around its axial direction of piston rod
Movement, thus the rotary motion of piston rod will lead to connection oil pipe on the piston rod will receive torque and with rotating with it.By
In the limitation of inner space of vehicle and hydraulic pipeline length, hydraulic pipeline rotates limited angle, excessive piston rod rotation
Angle will lead to hydraulic tube and the loosening of piston rod junction is even broken.
Summary of the invention
The purpose of the present invention is to solve the loosenings of hydraulic oil pipe existing in the prior art and piston rod junction very
To breakage problem, a kind of structure for limiting the piston rod rotary motion of MacPherson type hydro-pneumatic spring is provided.
The purpose of the present invention is what is be achieved through the following technical solutions.
A kind of structure limiting the piston rod rotary motion of MacPherson type hydro-pneumatic spring, comprising: locking nut, steering hinge are solid
Fixed end, turns to articulate end, oscillating bearing at pin；
It turns to hinge fixing end, pin and turns to articulate end composition and turn to hinge；It turns to hinge fixing end and is fixed on work
It on stopper rod, turns on the piston rod that hinge fixing end is located between upper top glue and hydraulic oil pipe, turns to hinge fixing end and pin connects
It connects, turns to articulate end and pass through oscillating bearing and pin connection；Oscillating bearing is fixed on vehicle body.
Steering hinge fixing end center is provided with through-hole, for passing through for piston rod, then passes through locking nut and piston
Bar is fixedly connected.
The course of work: it when piston rod moves up and down, drives steering hinge fixing end to move up and down together, it is solid to turn to hinge
Fixed end can be rotated around pin, and then driven and turned to articulate end motion；Since the vibration that body movement generates leads to piston rod
It vibrates up and down, while also resulting in piston rod and all around swinging；Hydro-pneumatic spring cylinder body, upper top glue are fixed on vehicle body, limitation
The swing of piston rod all around；On the piston rod when lower movement, turns to hinge fixing end, pin, turns to articulate end composition
Hinge is turned to, steering hinge fixing end, which drives, sells and then drive steering articulate end motion；Articulate end is turned to along joint
Bearing is swung up and down；Oscillating bearing limits the transverse movement for turning to articulate end, thus controls piston rod along axial
The rotary motion in direction.
Beneficial effect
A kind of structure of limitation MacPherson type hydro-pneumatic spring piston rod rotary motion of the invention has structure simple, easy
In easily fabricated and maintenance, safe and reliable feature.It can limit and connect oil pipe on the piston rod with the rotation of piston rod
Then rotation, to reduce the probability of hydraulic oil pipe and the damage of piston junction, improve the safety of hydro-pneumatic spring, reliability and
Durability.Hydraulic oil pipe and piston rod can safely and effectively work for a long time.

Specific embodiment
In order to illustrate the technical characterstic of this programme, below by specific embodiment, and its attached drawing is combined, to this hair
Bright patent is described in detail.
Embodiment 1
As shown in Figure 1, a kind of piston rod construction design for limiting the piston rod rotary motion of MacPherson type hydro-pneumatic spring, packet
It includes: hydro-pneumatic spring cylinder body 1, top tray 2, top tray bearing 3, upper top glue 4, hexagonal flange locking nut 5, piston rod 6, hydraulic oil
Pipe 7, locking nut 8 turn to hinge fixing end 9, pin 10, turn to articulate end 11, oscillating bearing 12.
Hydro-pneumatic spring cylinder body 1 is fixed on vehicle body.Piston rod 6 sequentially passes through top tray bearing 3, upper top glue 4, hexagonal flange
Locking nut 5, the through-hole for turning to 9 centre of hinge fixing end, locking nut 8,6 upper end of piston rod are connected with hydraulic oil pipe 7；Pop-up
It is integrated that dish axle, which holds 3 with top tray 2,；Upper top glue 4 is bolted on vehicle body, hexagonal flange locking nut 5 and piston rod 6
On shaft shoulder cooperation it is fixed on push up glue 4 and top tray bearing 3.
As shown in figure 3, turning to hinge fixing end 9, pin 10, turning to the composition steering hinge of articulate end 11；Turn to hinge
9 center of fixing end is provided with through-hole, and through-hole diameter is identical as 6 outer diameter of piston rod, for passing through for piston rod, then passes through locking nut
8 are fixedly connected with piston rod 6；It turns to hinge fixing end 9 to be fixedly connected on piston rod 6, turns to hinge fixing end 9 and be located at upper top
On piston rod 6 between glue 4 and hydraulic oil pipe 7；Hinge fixing end 9 is turned to connect with pin 10；Articulate end 11 is turned to pass through
Oscillating bearing 12 is connect with pin 10；Oscillating bearing 12 is fixed on vehicle body, another termination accumulator of hydraulic oil pipe 7.
Detailed operation is as follows:
When body vibrations, hydro-pneumatic spring is and then vibrated with vehicle.As shown in Figure 1, upper top glue 4 is fixed by nuts on vehicle body,
Hydro-pneumatic spring cylinder body 1 and upper top glue 7 limit the swing that piston rod 6 controls forwards, backwards；Top tray 2 and top tray bearing 3 are one
Body, top tray 2 can be axially moved around piston rod 6, and piston rod 6 is not influenced by this rotary motion.
As shown in figure 3, turning to hinge fixing end 9, pin 10, turning to the composition steering hinge of articulate end 11.Turn to hinge
Fixing end 9 is fixed on the piston rod, when piston rod 6 moves up and down, drives steering hinge fixing end 9 to move up and down together, turns
It connects together to hinge fixing end 9, pin 10 and steering articulate end 11, turns to hinge fixing end 9 and drive pin 10 and then drive
Articulate end 11 is turned to move；Articulate end 11 is turned to swing up and down along oscillating bearing 12；Oscillating bearing 12 is fixed on
On vehicle body, oscillating bearing 12 limits the transverse movement for turning to articulate end 11, thus controls piston rod 6 in axial direction
Rotary motion；6 top of piston rod connect hydraulic oil pipe 7,7 other end of hydraulic oil pipe connect an accumulator, suspension it is opposite
Movement causes piston rod 6 and hydro-pneumatic spring cylinder barrel relative motion, and the oil liquid sucking and discharge in hydro-pneumatic spring cylinder barrel cause
The expansion and compression of gas in accumulator, gas play elastic reaction.
