Abstract
The utility model provides a rear transition swing arm. One end of an arm body is a connecting hole hinged to a steering pull rod while the other end of the same is a rod sleeve, the rod sleeve and a rod body are of an integrally-forged structure, and the middle of the arm body is hinged on a vehicle frame. Compared with the prior art, the rear transition swing arm has the advantages of simple structure, light weight and high strength.
Description
Technical field
The utility model belongs to a kind of rear transition swing arm.
Background technology
The soldering member of former employing, turns to intermediate arm body and bearing carrier ring to carry out seam, and in order to guarantee welding performance, the low-carbon steel material of employing, exists drawback:
1, be prone to sealing-off situation;
2, be prone to crack of weld.
Due to the low carbon materials adopting, heat treatment hardness is on the low side, and plastic deformation easily occurs the taper hole coordinating with tie rod ball pin, and looseness then causes turning to vibration.
Summary of the invention
Technical matters to be solved by this invention be to provide a kind of after transition swing arm, after this transition swing arm have advantages of lightweight, intensity is large.
For achieving the above object, the technical program is as follows:
Transition swing arm after a kind of, comprises arm body, and described arm body is that one end is the connecting bore hinged with steering track rod, and the other end is and the bar cover that turns to midship mounting to be connected that described bar overlaps and the integrated forging structure of the body of rod; The centre of arm body is the hinge hole being hinged on vehicle frame.
Further, described arm body be positioned in the middle of the two ends of hinge hole be provided with not the loss of weight district through arm body along arm body bearing of trend.
Further, described bar cover axis hole is perpendicular to arm body, and the two ends of bar cover is higher than arm body.
Further, between described bar cover and arm body, be provided with transition region, bar cover and arm body rounding off.
Further, described arm body overlaps with bar the one end contacting and is provided with and strengthens district with the region contacting of bar cover, and strengthen district has arm body to extend to the maximum end of body of rod external diameter always.
Further, described loss of weight district is only positioned on a side of arm body.
Further, described bar cover is positioned at the outermost end of rear-swing arm.
Further, the outer end of described bar cover is the tubular structure of intermediate drum two ends contracting.
Further, described bar cover is provided with the reinforcement district of being extended by Xiang Gantao two ends, arm surface with arm body connecting portion two ends.
Principle of work of the present utility model and working process are as follows:
The utility model mainly comprises arm body, is respectively connecting bore and bar cover at the two ends of arm body, and middle part is
Hinge hole, can carry out arm body by hinge hole hinged fixingly like this, is being connected with steering track rod and steering actuation cylinder respectively, thereby reaches the object of assisted diversion in the connecting bore at arm body two ends and bar cover.
Arm body of the present utility model and bar cover, for forging integral structure rather than welded structure, are compared welded structure, and workpiece strength is larger.
Arm body is provided with loss of weight district, and loss of weight district is not through arm body, like this, can guarantee the intensity of whole arm body, the weight of integral arms body can be alleviated again.
Bar cover axis hole upright arm body, in motion process, two-freedom is vertical, does not have the pressure of side direction, and bar cover two ends are higher than arm body simultaneously, and contact surface is larger, can finely firmly be connected with connector, guarantees Joint strenght.
Between bar cover and arm body, be provided with transition region and strengthen district, further can guarantee intensity between the two.
Bar cover is positioned at the outermost end of arm body, and arm body and bar inner room are provided with and strengthen district and transition region and will whole rear transition swing arm carry out round and smooth and strengthen processing.
Bar cover is the tubular structure of intermediate strand both sides contracting, has guaranteed the intensity of bar cover self, prevents slight crack.
accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, the accompanying drawing the following describes is only some embodiment that record in the application, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing;
Fig. 1 is the main TV structure schematic diagram of the utility model;
Fig. 2 is that the utility model is looked up structural representation.
The specific embodiment
The correlation technique content of not addressing below all can adopt or use for reference prior art.
In order to make those skilled in the art person understand better the technical scheme in the application, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only the application's part embodiment, rather than whole embodiment.Based on the embodiment in the application, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all should belong to the scope of the application's protection.
As shown in Figure 1, 2, a kind of rear transition swing arm, comprises arm body 1, and one end of described arm body 1 is the connecting bore hinged with steering track rod, the bar cover 2 that the other end is and turns to intermediate arm support to be connected, described bar cover 2 and the integrated forging structure of the body of rod; The centre of arm body 1 is the hinge hole 3 being hinged on vehicle frame.
Described arm position 1 is provided with the not loss of weight district through arm body in the two ends of middle hinge hole along arm body bearing of trend; And described loss of weight district is only positioned on a side of arm body, can certainly can establish loss of weight district in two ends.
Described bar cover 2 is positioned at the side of rear transition swing arm, and the axis hole of bar cover 2 is perpendicular to arm body 1, and the two ends of bar cover 2 is higher than arm body 1; Between bar cover 2 and arm body 1, be provided with transition region 5, bar cover 2 and arm body 1 both rounding ofves; Meanwhile, arm body 1 is provided with and strengthens district with the region contacting of bar cover with bar cover 2 one end that contact, and strengthen district has arm body to extend to the maximum end of body of rod external diameter always.
The outer end of described bar cover 1 is the tubular structure of intermediate drum two ends contracting.
The macropore connection that bar overlaps above turns to intermediate arm support; Three holes below connect respectively and turn to centre link and steering actuation cylinder.
When use, rear transition swing arm is connected with turning to intermediate arm support, and on fixing and vehicle frame, by the pull bar being connected with hinge hole, the moment of deflector output arm is delivered to this rear transition swing arm, transmit torque on the track arm of front axle by the other hinge hole of this transition swing arm again, thereby play the effect turning to, in the transmittance process of power, this transition arm also has a hinge hole to be connected with servo cylinder, has played the effect of power steering.
The above is only the application's preferred implementation, makes those skilled in the art can understand or realize the application.To be apparent to one skilled in the art to the multiple modification of these embodiment, General Principle as defined herein can, in the case of not departing from the application's spirit or scope, realize in other embodiments.Therefore, the application will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
