Description
Technical field
This utility model relates to hydraulic cylinder technical field, particularly relates to a kind of bulb hinged hydraulic pressure
Cylinder.
Background technology
Hydraulic cylinder in automotive suspension, the general hinge using hinged plate hole to install oscillating bearing additional is even
Connect mode, to adapt to the motion of automotive suspension.Ideally, the cylinder body of hydraulic cylinder is the most only subject to
Axial force；But, in practice, the small movements that the movement clearance of machinery causes, or machinery
The small movements that elastic deformation causes so that it is cylinder body also suffers from radial force, the most also can make hinge
Fishplate bar and cylinder body produce with other parts and clash into, and trigger noise.
Utility model content
The technical problems to be solved in the utility model is to provide one it can be avoided that bear radial force
Bulb hinged hydraulic cylinder.
For solving the problems referred to above, this utility model provides a kind of bulb hinged hydraulic cylinder, described ball
Hinged hydraulic cylinder includes cylinder body and is located at the bulb hinged device of cylinder body one end, described cylinder body
Being provided with mounting groove, described bulb hinged device is fixed in mounting groove；Described bulb hinged fills
Put and include bulb, sphere block, dust ring and fixture, described bulb, sphere block,
Dust ring and fixture are in overlap is located at mounting groove successively, and fixture is connected ball with cylinder body
Head, sphere block and dust ring are limited in mounting groove, and described bulb can be in sphere block and peace
Rotating in the cavity that tankage combination is formed, described bulb can be formed at sphere block and mounting groove
Rotate in cavity.
Further, described mounting groove includes that hemispherical mounting groove, sphere fix groove and locking
Groove, described sphere fixes groove between hemispherical mounting groove and locking slot.
Further, described bulb includes bulb body and the connector being located on bulb body,
Described connector is provided with connection screw thread.
Further, described bulb body is provided with at least one lubrication groove.
Further, the described cylinder body other end also is provided with bulb hinged device.
This utility model bulb hinged hydraulic cylinder installs bulb on cylinder body additional, and bulb can on cylinder body
Rotate, thus dissolved the power that cylinder body bears on non axial, extend the service life of cylinder body,
Noise will not be produced.
Accompanying drawing explanation
Fig. 1 is the structural representation of the better embodiment of this utility model bulb hinged hydraulic cylinder
Figure.
Fig. 2 is the partial enlarged drawing of A in Fig. 1.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the better embodiment of this utility model bulb hinged hydraulic cylinder
Including cylinder body 1 and two bulb hinged devices being located at cylinder body 1 two ends, described cylinder body 1
Two ends are provided with mounting groove, and said two bulb hinged device is separately fixed in two mounting grooves.
In other embodiments, cylinder body 1 is installed bulb 2 articulated mounting the most only, according to
Demand is configured.
Described bulb 2 articulated mounting includes bulb 2, sphere block 3, dust ring 4 and consolidates
Locking member 5, described bulb 2, sphere block 3, dust ring 4 and fixture 5 overlap successively set
In mounting groove.Described bulb 2 includes bulb body 21 and the company being located on bulb body 21
Junctor 22, described connector 22 is provided with connection screw thread 221；Set on described bulb body 21
There is multiple lubrication groove 211, in lubrication groove 211, lubrication can be played by oil addition.Institute
Stating sphere block 3 and form cavity with mounting groove, described bulb body 21 is located in cavity, institute
State bulb body 21 to rotate in this cavity.Described fixture 5 makes in being arranged in mounting groove
It is fixed with cylinder body 1, thus is limited to bulb 2, sphere block 3 and dust ring 4 install
In groove, described fixture 5 can use locking nut.Described dust ring 4 is by bulb 2 and ball
Face block 3 is sealed in mounting groove, guarantee simultaneously bulb 2 rotate time, dust ring 4 remains to
Contact with bulb 2, it is to avoid extraneous dust enters between bulb 2 and sphere block 3 or cylinder body 1.
Described mounting groove includes that hemispherical mounting groove, sphere fix groove and locking slot, described ball
Groove is fixed between hemispherical mounting groove and locking slot in face, described hemispherical mounting groove, sphere
Fixing groove and locking slot are stepped, are gradually reduced diameter.Described spheroid is located at hemispherical and installs
In groove, described sphere block 3 and dust ring 4 are located at sphere and fix in groove, described fixture 5
It is located in described locking slot.
During use, when cylinder body 1 is by radial force, bulb 2 is at the spherical mounting groove of cylinder body 1
Interior rotation, thus dissolve the radial force that cylinder body 1 holds, it is to avoid cylinder body 1 collision etc., extends
In the service life of cylinder body 1, also will not produce noise simultaneously.
These are only embodiment of the present utility model, not thereby limit of the present utility model specially
Profit scope, every equivalent structure utilizing this utility model description and accompanying drawing content to be made, directly
Connect or be indirectly used in other relevant technical fields, the most in like manner protect in patent of the present utility model
Within the scope of protecting.
