Description
Technical field
The present invention relates to a kind of MacPherson type and hang hydro-pneumatic spring；It is specifically related to a kind of MacPherson type hydro-pneumatic spring that limits live
The structure of stopper rod rotary motion, belongs to hydro-pneumatic spring field.
Background technology
The forward mounting of common car is generally MacPherson type and hangs, as it is shown in figure 5, it is the most popular that MacPherson type hangs
One of independent suspension.The primary structure that MacPherson type hangs i.e. is made up of plus vibroshock helical spring, and vibroshock is permissible
Avoid to do the vibration of above-below direction to the phenomenon of front, rear, left and right skew, restriction spring during helical spring stress, it is possible to
Soft or hard and the performance of suspension is set by the stroke length of vibroshock and degree of tightness.MacPherson type is suspended on the table on road-ability
Existing satisfactory, its structural volume is little, can effectively expand interior passenger space.
When vehicle oleo-pneumatic suspension uses this kind of suspension type, due to its can not limit piston rod around its axial rotation
Motion, so the rotary motion of piston rod can cause the oil pipe connected on the piston rod can be by moment of torsion with rotating with it.By
In inner space of vehicle and the restriction of conduit under fluid pressure its length, the conduit under fluid pressure anglec of rotation is limited, and excessive piston rod rotates
Angle can cause hydraulic tube even to rupture with loosening of piston rod junction.
Summary of the invention
The invention aims to solve loosening very of hydraulic oil pipe and piston rod junction present in prior art
To breakage problem, it is provided that a kind of structure limiting MacPherson type hydro-pneumatic spring piston rod rotary motion.
It is an object of the invention to be achieved through the following technical solutions.
A kind of structure limiting MacPherson type hydro-pneumatic spring piston rod rotary motion, including: locking nut, turns to hinge solid
Fixed end, sell, turn to articulate end, oscillating bearing；
Turn to the fixing end of hinge, sell and turn to articulate end composition to turn to hinge；Turn to hinge to fix end and be fixed on work
On stopper rod, turn to hinge to fix on end piston rod between upper top glue and hydraulic oil pipe, turn to the fixing end of hinge with pin even
Connect, turn to articulate end to be connected with pin through oscillating bearing；Oscillating bearing is fixed on vehicle body.
Described turn to hinge to fix end center to have through hole, passing for piston rod, then by locking nut and piston
Bar is fixing to be connected.
Work process: when piston rod moves up and down, drive turns to hinge to fix end and moves up and down together, turns to hinge solid
Fixed end can rotate around pin, and then drive turns to articulate end motion；The vibration produced due to body movement causes piston rod
Up-down vibration, also results in piston rod simultaneously and all around swings；Hydro-pneumatic spring cylinder body, upper top glue are fixed on vehicle body, limit
Piston rod swing all around；When moving down, turn to hinge fixing to hold, sell, turn to articulate end to form
Turn to hinge, turn to hinge fixing end band untie-sell and then drive to turn to articulate end motion；Turn to articulate end along joint
Bearing swings up and down；Oscillating bearing limits the transverse movement turning to articulate end, thus controls piston rod vertically
The rotary motion in direction.
Beneficial effect
A kind of structure limiting MacPherson type hydro-pneumatic spring piston rod rotary motion of the present invention, has simple in construction, easily
In easily fabricated and maintenance, safe and reliable feature.Can limit and connect oil pipe on the piston rod along with the rotation of piston rod
Then rotate, thus reduce the probability that hydraulic oil pipe and piston junction are damaged, improve the safety of hydro-pneumatic spring, reliability and
Durability.Hydraulic oil pipe and piston rod can the most safely and effectively work.

Detailed description of the invention
In order to be able to illustrate the technical characterstic of this programme, below by specific embodiment, and combine its accompanying drawing, to this
Bright patent is described in detail.
Embodiment 1
As it is shown in figure 1, a kind of piston rod construction design limiting MacPherson type hydro-pneumatic spring piston rod rotary motion, bag
Include: 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, hinge is turned to fix 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, turn to hinge to fix the through holes in the middle of end 9, locking nut 8, piston rod 6 upper end to be connected with hydraulic oil pipe 7；Pop-up
Pallet 2 caught up with by dish bearing 3 is one；Upper top glue 4 is bolted on vehicle body, hexagonal flange locking nut 5 and piston rod 6
On the shaft shoulder coordinate fixing upper top glue 4 and top tray bearing 3.
As it is shown on figure 3, turn to hinge to fix end 9, pin 10, turn to articulate end 11 composition to turn to hinge；Turn to hinge
Fixing end 9 centers have through hole, and through-hole diameter is identical with piston rod 6 external diameter, passing for piston rod, then passes through locking nut
8 fixing with piston rod 6 are connected；Turn to the fixing end 9 of hinge to be fixedly connected on piston rod 6, turn to the fixing end 9 of hinge to be positioned at top
On piston rod 6 between glue 4 and hydraulic oil pipe 7；The fixing end 9 of hinge is turned to be connected with pin 10；Articulate end 11 is turned to pass
Oscillating bearing 12 is connected with pin 10；Oscillating bearing 12 is fixed on vehicle body, another termination accumulator of hydraulic oil pipe 7.
Detailed operation is as follows:
During body vibrations, hydro-pneumatic spring and then vibrates with car.As it is shown in figure 1, upper top glue 4 is fixed on vehicle body by nut,
Hydro-pneumatic spring cylinder body 1 and upper top glue 7 limit the swing of piston rod 6 left and right forwards, backwards；Top tray 2 and top tray bearing 3 are one
Body, top tray 2 can be around piston rod 6 axially-movable, and piston rod 6 is not affected by this rotary motion.
As it is shown on figure 3, turn to hinge to fix end 9, pin 10, turn to articulate end 11 composition to turn to hinge.Turn to hinge
Fixing end 9 is fixing on the piston rod, when piston rod 6 moves up and down, drives and turns to the fixing end 9 of hinge to move up and down together, turn
Fix end 9, pin 10 to hinge and turn to articulate end 11 to connect together, turn to hinge fixing end 9 band untie-sells 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 turning to articulate end 11, thus controls piston rod 6 in axial direction
Rotary motion；Piston rod 6 top connects hydraulic oil pipe 7, and hydraulic oil pipe 7 other end connects an accumulator, suspension relative
Motion causes piston rod 6 and hydro-pneumatic spring cylinder barrel relative motion, and the fluid in hydro-pneumatic spring cylinder barrel sucks and discharge causes
The expansion of gas and compression in accumulator, gas plays elastic reaction.
