Abstract
The utility model discloses a lower suspension arm ball pin assembly, which comprises a main body (1), a ball seat (2) and a ball pin (3). The main body (1) is fixedly connected with the ball seat (2), one end of the ball pin (3) is located in the ball seat (2), a dust cover (4) is arranged outside the ball pin (3), the upper end of the dust cover (4) is provided with a sealing port (4.1), the contact surface between the sealing port (4.1) and the ball pin (3) is of a 'labyrinth seal' structure, wherein definition of the 'labyrinth seal' is that inner oil chambers and outer channels of machine are produced as a labyrinth so as to increase medium leakage path and medium leakage friction, and sequentially reduce medium loss. The sealing port is of a 'labyrinth seal' structure, thus, the dust cover (4) has higher wear resistance and can prevent dust and cement from entering into the ball pin (3) more effectively, and the service life of the lower suspension arm ball pin is prolonged.
Description
Technical field
The utility model relates to automotive field, is specifically a kind of lower swing arm ball pin assembly.
Background technique
At present, lower swing arm ball pin assembly is the important component part of automobile suspension system, and lower swing arm one end is connected with vehicle frame, and the lower swing arm the other end is connected with knuckle by ball pin.Existing lower swing arm ball pin assembly is provided with dust-proof cover, for preventing sand and dust, muddy water from entering lower swing arm ball pin, affects performance.But above-mentioned lower swing arm ball pin assembly still has some shortcomings part: the dust-proof cover upper end of existing lower swing arm ball pin assembly is provided with sealed mouth, sealed mouth socket ball pin outside, the surface of contact of sealed mouth and ball pin is " sawtooth pattern sealing " structure, makes the wear resistance of dust-proof cover poor, and working life is shorter.
Model utility content
Technical problem to be solved in the utility model: provide a kind of dust-proof cover wear resistance good lower swing arm ball pin assembly.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of lower swing arm ball pin assembly, it comprises body, ball seat and ball pin, described body is fixedly connected with ball seat, ball pin one end is positioned at ball seat, ball pin outside is provided with dust-proof cover, and dust-proof cover upper end is provided with sealed mouth, and the surface of contact of described sealed mouth and ball pin is " maze type sealing " structure.
Adopt said structure, the advantage that the utility model has is: described " maze type sealing " be defined as machine intimate grease chamber is done with outside passage as labyrinth, to increase dielectric leakage road strength and dielectric leakage frictional force, thus minimizing relative permitivity.Described sealed mouth adopts the structure of " maze type sealing ", makes the wear resistance of dust-proof cover better, can more effectively prevent that sand and dust, muddy water from entering ball pin, makes the working life of lower swing arm ball pin longer.
As preferably, described ball pin upper end is provided with knuckle, knuckle is positioned at sealed mouth outside, described dust-proof cover is circumferentially provided with annular protrusion on the position of correspondence outside knuckle, annular protrusion and dust-proof cover are integral type structure, because dust-proof cover is that elastic material is made, dust-proof cover is circumferentially provided with annular protrusion on the position of correspondence outside knuckle, make annular protrusion and the laminating of knuckle periphery wall, and then formation dust-proof cover first protection, prevent that sand and dust, muddy water from entering ball pin by knuckle, sealing effect is better, and structure is simpler.
As preferably, described body is provided with mounting hole, and mounting hole is three and distribution triangular in shape, is convenient to the installation of lower swing arm ball pin assembly and fixing, and structure is simpler.
As preferably, described dust-proof cover lower end is connected with body by jump ring, more convenient when dust-proof cover is mounted and dismounted, and structure is simpler.
As preferably, described body is also provided with ball pin guard shield, and described ball pin guard shield is positioned at ball pin outside, further ball pin is protected, and structure is simpler.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of a kind of lower swing arm ball pin assembly of the utility model.
Fig. 2 is the plan structure schematic diagram of a kind of lower swing arm ball pin assembly of the utility model.
As shown in the figure: 1-body, 2-ball seat, 3-ball pin, 4-dust-proof cover, 4.1-sealed mouth, 4.2-annular protrusion, 5-knuckle, 6-mounting hole, 7-jump ring, 8-ball pin guard shield.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1 and Figure 2, a kind of lower swing arm ball pin assembly, it comprises body 1, ball seat 2 and ball pin 3, described body 1 is fixedly connected with ball seat 2, ball pin 3 one end are positioned at ball seat 2, ball pin 3 outsides are provided with dust-proof cover 4, and dust-proof cover 4 upper ends are provided with sealed mouth 4.1, and described sealed mouth 4.1 is " maze type sealing " structure with the surface of contact of ball pin 3.
Described " maze type sealing " be defined as machine intimate grease chamber is done with outside passage as labyrinth, to increase dielectric leakage road strength and dielectric leakage frictional force, thereby reduce relative permitivity.Described sealed mouth 4.1 adopts the structure of " maze type sealing ", makes the wear resistance of dust-proof cover 4 better, can more effectively prevent that sand and dust, muddy water from entering ball pin 3, makes the working life of lower swing arm ball pin longer.
Described ball pin 3 upper ends are provided with knuckle 5, knuckle 5 is positioned at sealed mouth 4.1 outsides, described dust-proof cover 4 is provided with annular protrusion 4.2 on the position of knuckle 5 outer circumferential correspondences, annular protrusion 4.2 is integral type structure with dust-proof cover 4, because dust-proof cover 4 is made for elastic material, dust-proof cover 4 is provided with annular protrusion 4.1 on the position of knuckle 5 outer circumferential correspondences, make annular protrusion 4.1 and knuckle 5 periphery wall laminatings, and then formation dust-proof cover 4 firsts protection, prevent that sand and dust, muddy water from entering ball pin 3 by knuckle 5, sealing effect is better, and structure is simpler.
Described body 1 is provided with mounting hole 6, and described mounting hole 6 is three and distribution triangular in shape, is convenient to the installation of lower swing arm ball pin assembly and fixes, and structure is simpler; Described dust-proof cover 4 lower ends are connected with body 1 by jump ring 7, more convenient when dust-proof cover 4 is mounted and dismounted, and structure is simpler; Described body 1 is also provided with ball pin guard shield 8, and described ball pin guard shield 8 is positioned at ball pin 3 outsides, further ball pin 3 is protected, and structure is simpler.
