Abstract
The utility model relates to a maintenance-free spherical hinge ball seat. The outer surface of a ball seat body is a cylindrical shape, a barb is arranged at the lower end of the cylindrical shape while a flange is arranged at the upper end, an inner cavity of the ball seat body comprises an oil storage groove and a space matching with the curve surface of the outer surface of a ball pin head, a plurality of open grooves are arranged on the surface of the space matching with the curve surface of the outer surface of the ball pin head, the open grooves of the ball seat body are provided with reinforcing blocks on the upper half area of the circumference of the ball pin head, and the oil storage groove is communicated with the open grooves. Compared with the prior art, the maintenance-free spherical hinge ball seat has the advantages that 1 the ball seat is made of polyformaldehyde materials, the oil storage groove penetrating through the surface of a ball pin is arranged on the ball seat for adding high-quality lubricating grease for lubrication, and the seat ball needs no maintenance during the service life, and 2 the flange at the upper end of the ball seat and an end cover are jointly pressed into a mounting groove of a casing of a spherical hinge, thereby being excellent in sealing performance and guaranteeing normal use of the ball pin in environment with muddy water, high temperature and low temperature.
Description
Technical field:
The utility model relates to a kind of suspension device for vehicle, the non-maintaining spherical hinge ball seat of using more specifically to the upper and lower control arm of a kind of independent suspension.
Background technique:
Along with the development of freeway net, increasing automobile suspension arrangement adopts independent suspension structure to increase substantially the requirement to aspects such as vehicle driving smoothness and control stabilities that is brought to satisfy the speed of a motor vehicle.Wherein, connect the needs that non-maintaining spherical hinge that upper and lower control arm uses must satisfy wheel maximum jitter amount and steering locking angle, and present used spherical hinge unreasonable structure, particularly the ball socket structure of the sphere lower pair of forming with ball stud is undesirable, big, the lubricated inconvenience in surface of contact gap, cause maintenance frequent, have influence on the overall performance of automobile.
The model utility content:
The purpose of this utility model provides a kind of and ball stud no-float, whole life period to need not the non-maintaining spherical hinge ball seat of oiling at the prior art deficiency.
The purpose of this utility model is to realize by following measure: a kind of non-maintaining spherical hinge ball seat, its special way is, described ball seat body appearance is cylindric, cylindric underpart has a chamfering, upper end portion that one flange is arranged, the space that the ball seat chamber body matches by the store oil groove, with ball pin head appearance curved surface is formed, the described spatial surface that matches with ball pin head appearance curved surface has some opening slots, ball seat body openings groove has reinforced block in first zone of ball pin head diameter, and described store oil groove is communicated with opening slot.
Described ball seat body is divided into some by opening slot, and each piece has the stiffening rib that is connected with the ball seat body at the store oil groove.
The cylindrical surface of described ball seat body is provided with some grooves.
Compared with prior art, adopt the non-maintaining spherical hinge ball seat that the utility model proposes, have following advantage: 1) ball seat adopts polyformaldehyde material to make, and has the oil storage tank that connects the ball pin surface, the senior grease lubrication of annotating, whole life period Maintenance free.2) the ball seat upper end flange is in end cap is pressed into spherical hinge housing mounting groove, and sealing is good, guarantees that the ball pin can normally use under muddy water and high and low temperature environment.
Description of drawings:
Fig. 1 is the utility model example structure schematic representation.
Fig. 2 is Fig. 1 embodiment A-A sectional structure chart.
Fig. 3 is Fig. 1 Embodiment B-B sectional structure chart.
Embodiment:
Below in conjunction with accompanying drawing embodiment is elaborated:
Fig. 1～Fig. 3 has provided the utility model example structure schematic representation.Among the figure, a kind of non-maintaining spherical hinge ball seat, described ball seat body 1 appearance is cylindric, cylindric underpart has a chamfering 11, upper end portion that one flange 12 is arranged, the space 4 that the ball seat chamber body matches by store oil groove 3, with ball pin head appearance curved surface is formed, described 4 surfaces, space that match with ball pin head appearance curved surface have some opening slots 5, and ball seat body openings groove has reinforced block 6 in first zone of ball pin head diameter, and described store oil groove is communicated with opening slot.Described ball seat body is divided into some by opening slot, and each piece has the stiffening rib 2 that is connected with the ball seat body at the store oil groove.The cylindrical surface of described ball seat body is provided with some grooves 8.Described ball seat body adopts polyformaldehyde material to make, ball seat body appearance is cylindric, cylindric underpart has a chamfering and spherical hinge shell inner cavity to match, its upper end portion has a flange and spherical hinge end cap together to be installed in the mounting groove of spherical hinge housing, not only place restrictions on the axial displacement and the good airproof performance of ball seat, the groove that the ball seat body is cylindric appearance can prevent the rotation of ball seat, returns the expansion of ball seat and allows some leeway.Described ball seat chamber body and ball pin head appearance curved surface match, and make its tight contact, eliminate the shaped position tolerance, are difficult for taking place play during the motion of ball pin.Fig. 2, Fig. 3 have provided the section of structure of present embodiment ball seat, utilize the elasticity sex change of opening slot, can easily the ball guide be gone in the ball seat.The opening slot number be 6～8 comparatively suitable.The opening slot that utilize to connect the ball pin surface communicates with ball seat chamber body store oil groove, and opening slot and store oil groove all can be stored senior lubricating grease, need not to add in addition maintenance at the whole life period of ball pivot.
The foregoing description does not constitute restriction of the present utility model, and all employings are equal to the technological scheme that form obtained of replacement or equivalent transformation, all drop within the protection domain of the present utility model.
