Description
Technical field
The utility model relates to a kind of connection structure of automobile drive axle propelling rod, is specifically related to a kind of automobile drive axle propelling rod support with anti-misloading function.
Background technology
On existing automobile drive axle, front end face A and the aft end face B of propelling rod support are finished surface, and the processing request of these both ends of the surface is consistent, usually adopt the mode of milling flat to process.As shown in Figure 1, Figure 2 with shown in Fig. 5, propelling rod support 1 mounting means correct with two neck ball end 6 is: the aft end face B of propelling rod support 1 is used for the two neck ball end 6 of location and installation, and the front end face A of propelling rod support 1 is used for mounting nuts.But, because the front end face A of propelling rod support in prior art 1 is consistent with the processing request of aft end face B, two neck ball end 6 cannot be distinguished by domestic consumer when changing propelling rod should be loaded on front end face A or aft end face B, very easily cause misloading, and then cause the attitude of automobile drive axle and wheelbase to change, make car load occur series of problems.
Summary of the invention
The purpose of this utility model is consistent with aft end face processing request for the front end face on existing automobile drive axle propelling rod support, domestic consumer cannot distinguish when changing propelling rod be loaded on front end face or aft end face, easily cause the defect of misloading, provide a kind of have anti-misloading function automobile drive axle propelling rod support.
For achieving the above object, technical solution of the present utility model is:
A kind of anti-misloading automobile drive axle propelling rod support, comprise support body, described support body is provided with two pillars, two described pillars are equipped with pillar through hole, and front end face is led in one end of described pillar through hole, and the other end leads to aft end face, described aft end face is the plane of Milling Process, described aft end face contacts with the connecting portion of two neck ball end, and described connecting portion is provided with the pin-and-hole corresponding with described pillar through hole, and the pillar through hole aperture ream on described front end face has counter sink.
Further, the radius of described counter sink is more than or equal to 3 times of radiuses of described pillar through hole, and is less than the ultimate range of axle center to connecting portion end of connecting portion pin-and-hole.
Compared with prior art, the beneficial effects of the utility model are:
1. the processing mode of the utility model employing spot-facing processes an end face on the pillar of propelling rod support, this end face is stoped to position two neck ball end, make former and later two end faces of on propelling rod support two pillars have obvious distinguishing characteristics, effectively prevent the misloading of domestic consumer when self-changeable propelling rod;
2. after the utility model changes the processing mode of the front end face on propelling rod support into spot-facing by milling flat, region on front end face A except pillar through hole aperture does not all need reprocessing, decrease the working (finishing) area of front end face A, the processing and fabricating of propelling rod support is made to become easier, reduce machinework cost, improve machinework efficiency;
3. the utility model structure is simple, easy to process, reduces machinework cost, improves machinework efficiency, also have good anti-misloading function.

Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and with specific embodiment mode, the utility model to be described in further detail.
See Fig. 3 to Fig. 6, a kind of anti-misloading automobile drive axle propelling rod support, comprise support body 1, described support body 1 is provided with two pillars 7, two described pillars 7 are equipped with pillar through hole 8, front end face A is led in one end of described pillar through hole 8, the other end leads to aft end face B, described aft end face B is the plane of Milling Process, described aft end face B contacts with the connecting portion 9 of two neck ball end 6, described connecting portion 9 is provided with the pin-and-hole corresponding with described pillar through hole 8, and the pillar through hole 8 aperture ream on described front end face A has counter sink 5.
The radius of described counter sink 5 is more than or equal to 3 times of radiuses of described pillar through hole 8, and is less than the ultimate range of axle center to connecting portion 9 end of connecting portion 9 pin-and-hole.
Composition graphs 3 and Fig. 4, the support body 1 of propelling rod support is provided with the pillar 7 of two, two described pillars 7 are equipped with pillar through hole 8, and the longitudinal axis of the pillar through hole 8 on two described pillars 7 is parallel to each other, and pillar through hole 8 position on two described pillars 7 is contour; Described aft end face B is formed by Milling Process, and the aperture place ream of described front end face A upper supporting column through hole 8 has counter sink 5, and the bottom surface of described counter sink 5 is vertical with the longitudinal axis of pillar through hole 8 respectively with aft end face B.
The processing mode of this place employing spot-facing processes the front end face A on propelling rod support 1, make front end face A cannot locate the connecting portion 9 of two neck ball end 6, and make the front end face A on propelling rod support 1 and aft end face B have obvious distinguishing characteristics, make domestic consumer also can tell the correct attachment face of propelling rod easily, effectively prevent misloading during domestic consumer's self-changeable propelling rod; In addition, after changing the processing mode of the front end face A on propelling rod support into spot-facing by milling flat, region on front end face A except pillar through hole 8 aperture does not all need reprocessing, decrease the working (finishing) area of front end face A, the processing and fabricating of propelling rod support is made to become simpler, improve machinework efficiency, reduce machinework cost.
Composition graphs 5 and Fig. 6, after the through hole of bolt 3 in turn through the pin-and-hole of two neck ball end 6 connecting portion 9, pillar through hole 8 and pad 4, then be threaded with the nut 2 be positioned at outside described front end face A, utilize bolt 3 to be fixed on aft end face B by two neck ball end 6.Now the head of described bolt 3 is positioned at the outside of described aft end face B, the threaded shank of described bolt 3 is connected with the outside screw of nut 2 in front end face A, the contact surface of described pair of neck ball end 6 and pillar 7 is aft end face B of Milling Process, is by the bottom surface of ream counter sink 5 with the matching used packing ring of nut 24 and the contact surface of described pillar 7.
The utility model change be only the processing mode of the aperture place plane of front end face A upper supporting column through hole 8, and aft end face B is without any change, thus Fig. 5 is prior art assemble with two neck ball end after back view be also back view after the utility model is assembled with pair neck ball end simultaneously.In figure, the connecting through hole of two connecting portions 9 of described pair of neck ball end 6 is corresponding with the through hole of two pillars 7 respectively, then adopts two bolts 3 to be individually fixed on the aft end face B of two pillars 7 by two connecting portions 9 of two neck ball end 6.
Above content is the further description done the utility model in conjunction with detailed description of the invention, its mistake proofing principle contains drive axle upper traction bar support and lower thrust rod bearing, be not limited to indication front and rear surfaces herein, every propelling rod pillar and ball end connecting surface are milling plane, propelling rod pillar and nut contact surface are ream counter sink structure, can not think that concrete enforcement of the present utility model is confined to these explanations, for the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, the simple replacement made, all should be considered as belonging to protection domain of the present utility model.
