Abstract
The utility model relates to a connecting structure of a turning shaft and a swing arm of a truck. The connecting structure comprises a stabilizer bar and rocker arms located at the two ends of the stabilizer bar. The two ends of the stabilizer bar are respectively provided with a non-cylindrical irregular tubular connecting head end, the roots of the rocker arms are provided with irregular holes matched with the connecting head ends, and the rocker arms are installed on the stabilizer bar in an inserting mode and fixed through fixing devices. Due to the fact that the irregular holes of the mutually-connected connecting head ends are predicted to be non-circular surfaces, a whole non-circular connecting portion bears load when the torsion load around the axial direction of the stabilizer bar is borne. The connecting structure makes full use of materials, the welding process is not used, machining procedures are few, and the connecting structure is environmentally friendly.
Description
Technical field
The utility model relates to a kind of automobile suspension system, is specifically related to the connection structure of a kind of truck turning rotating shaft and swing arm.
Background technology
The truck of domestic enterprise's production at present, the trip shaft assembly majority that its operator's compartment suspension is used is made of left swing arm, right swing arm, stabilizer rod and other assembly parts.The trip shaft assembly stabilizer rod of this structure and left and right swing arm are that the mode by welding is connected in one in order to help body shell cab body to bear torque load around the stabilizer rod axis direction.Under such connection structure, the transmission of moment of torsion between swing arm and stabilizer rod relies on weld strength fully, and be insufficient to utilizing of material, simultaneously welding process and quality had higher requirements.
Summary of the invention
The utility model provides a kind of truck turning rotating shaft that need not weld and the connection structure of swing arm in order to overcome the deficiency of above technology.
The technical scheme that its technical matters that overcomes the utility model adopts is:
The connection structure of the rotating shaft of this truck turning and swing arm, the rocking arm that comprises stabilizer rod and be positioned at the stabilizer rod two ends, the different in nature tubulose that the two ends of described stabilizer rod is provided with non-cylindrical connects head end, described rocking arm root is provided with and the profiled holes that is connected head end and is complementary, and described rocking arm is plugged on stabilizer rod and by anchor fitting to be fixed.
Above-mentioned anchor fitting is a chock plug, and the external diameter of described chock plug is greater than the external diameter of described stabilizer rod connector stomidium.
The beneficial effects of the utility model are: because interconnective connection head end estimates that profiled holes is for being non-circular surfaces, therefore the even bearing load of whole non-round connecting bridge when the torque load that bears around the stabilizer rod axis direction, this kind structure is more abundant to the utilization of material.And do not adopt welding process, make manufacturing procedure still less, also more environmental protection.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that A-A in Fig. 1 is to cross-sectional view;
Fig. 3 is perspective view of the present utility model;
In figure, 1. stabilizer rod 2. rocking arm 3. chock plugs 4. connect head end 5. profiled holes.
The specific embodiment
Be described further below in conjunction with accompanying drawing 1,2 pairs of the utility model of accompanying drawing.
The connection structure of the rotating shaft of this truck turning and swing arm, the rocking arm 2 that comprises stabilizer rod 1 and be positioned at stabilizer rod 1 two ends, the different in nature tubulose that the two ends of described stabilizer rod 1 is provided with non-cylindrical connects head end 4, described rocking arm 2 roots are provided with and the profiled holes 5 that is connected head end 4 and is complementary, and described rocking arm 2 is plugged on stabilizer rod 1 and by anchor fitting to be fixed.Because interconnective connection head end 4 is estimated profiled holes 5 for being non-circular surfaces, the therefore even bearing load of whole non-round connecting bridge when the torque load that bears around stabilizer rod 1 axis direction, this kind structure is more abundant to the utilization of material.And do not adopt welding process, make manufacturing procedure still less, also more environmental protection.
Above-mentioned anchor fitting is a chock plug 3, and the external diameter of described chock plug 3 connects the external diameter of head end 4 endoporus greater than described stabilizer rod 1.The profiled holes shape that the shape of chock plug 3 is connected in head end 4 with stabilizer rod 1 is similar, when chock plug 3 is pressed in process in connecting head end 4, connect head end 4 swell material thickness attenuation, make it outside face and be close in profiled holes 5 on rocking arm 2, thereby realize rocking arm 2 is fixed on stabilizer rod 1.Connection structure timeliness not when being pressed into of chock plug 3 should be able to guarantee after assembling axially to apply specific load (this magnitude of load is different because of particular case, but should be less than 2t) along stabilizer rod 1, namely each constituent part is not want motion.
Claims (2)
