Abstract
The utility model provides a preceding knuckle, preceding knuckle includes knuckle body, preceding lower control arm spherical hinge and preceding lower control arm ball pivot hammer round pin, preceding lower control arm ball pivot hammer round pin with preceding lower control arm ball hinged joint, preceding lower control arm spherical hinge is installed on the knuckle body, a plurality of shaft holes have been offered to the lower tip of knuckle body, install the hub bearing in the shaft hole. The utility model discloses preceding knuckle can solve above space completely and arrange difficulty and intensity to be difficult to reach the current situation of requirement through improving the structure. And this kind of structure more accords with the requirement of kinematics space requirement and reliability, performance and the life -span that can improve the car by a wide margin.
Description
Technical field
The utility model relates to automotive field, and particularly a kind of front steering saves.
Background technology
At automotive field, the front steering of car joint is all generally casting or Forging Parts, its need to connect on car load wheel angle is total comprise before multiple vitals of Lower control arm spherical hinge.
Fig. 1 is the front view of front steering joint in prior art.Fig. 2 is the lateral plan of front steering joint in prior art.Fig. 3 is the mounting structure schematic diagram one of front Lower control arm spherical hinge in front steering joint in prior art.Fig. 4 is the mounting structure schematic diagram two of front Lower control arm spherical hinge in front steering joint in prior art.
As shown in Figures 1 to 4, described front steering joint can comprise: steering swivel body 10, front Lower control arm spherical hinge ball pin 20, front Lower control arm spherical hinge 30, brake clamp, steering track rod and shock absorber (not shown) etc.Wherein, the mounting hole inside face 11 of steering swivel hub bearing is irregular surface, and the space requirement such as hub spindle bearing bore 12 and machine up causes this place's wall thickness less, easily occurs failure risk.In addition, because front Lower control arm spherical hinge 30 place should transmit larger power again for installation and spherical hinge motion provide enough spaces, this makes steering swivel become very difficult and responsive at the structure design at this place.
Therefore, this area urgently in solving the problem, to obtain more reasonable structure design easily.
Utility model content
The technical problems to be solved in the utility model saves in front Lower control arm spherical hinge place structure design difficulty and the defect of sensitivity to overcome front steering in prior art, provides a kind of front steering to save.
The utility model solves above-mentioned technical matters by following technical proposals: a kind of front steering joint, its feature is, described front steering joint comprises steering swivel body, front Lower control arm spherical hinge and front Lower control arm spherical hinge ball pin, described front Lower control arm spherical hinge ball pin is connected with described front Lower control arm spherical hinge, described front Lower control arm spherical hinge is arranged on described steering swivel body, the bottom of described steering swivel body offers multiple axis hole, in described axis hole, be provided with hub bearing.
Preferably, the diameter of described axis hole is 65mm or 91.5mm.
Preferably, the bottom of described steering swivel body is provided with an installation end, and described front Lower control arm spherical hinge wears and is fixed in described installation end.
Preferably, fixed by anchor fitting between described front Lower control arm spherical hinge and the installation end of described steering swivel body.
Preferably, described anchor fitting is bolt and nut.
Preferably, the inside face of described axis hole is plane.
Positive progressive effect of the present utility model is:
The utility model front steering joint by modified node method, can solve completely above arrangement space difficulty and intensity be difficult to meet the requirements of present situation.And this structure more meets the requirement of kinematics space requirement and reliability, performance and the life-span of automobile significantly can be improved.

Detailed description of the invention
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, therefore the utility model is not by the restriction of following public specific embodiment.
Fig. 5 is the front view of the utility model front steering joint.Fig. 6 is the lateral plan of the utility model front steering joint.Fig. 7 is the mounting structure schematic diagram one of front Lower control arm spherical hinge in the utility model front steering joint.Fig. 8 is the mounting structure schematic diagram two of front Lower control arm spherical hinge in the utility model front steering joint.
As described in Fig. 5 to Fig. 8, a kind of front steering joint is disclosed in an embodiment of the utility model front steering joint, it comprises steering swivel body 40, front Lower control arm spherical hinge 50 and front Lower control arm spherical hinge ball pin 60, front Lower control arm spherical hinge ball pin 60 is connected with front Lower control arm spherical hinge 50, and front Lower control arm spherical hinge 50 is arranged on steering swivel body 40.Offer multiple axis hole 41 in the bottom of steering swivel body 40, hub bearing (not shown) is installed in axis hole 41.
Especially, the diameter of axis hole 41 is preferably 65mm or 91.5mm herein.The inside face of axis hole 41 is plane.Such steering swivel hub bearing is arranged in axis hole, the space requirement such as axis hole and machine up is easily met, not easily occurs failure risk.
Further, be provided with an installation end 42 in the bottom of steering swivel body 40, front Lower control arm spherical hinge 50 worn and is fixed in installation end 42.Fixed by anchor fitting between front Lower control arm spherical hinge 50 and steering swivel body 40.Described anchor fitting can be preferably bolt and nut 43.
In sum, the utility model front steering joint is improved by said structure, for spherical hinge motion provides enough large space, also provides larger space for machine up and assembling etc.The structure of the utility model front steering joint more meets the requirement of kinematics space requirement and reliability, effectively can significantly improve automotive performance and life-span.
