Abstract
The utility model discloses a bulb is sold for vehicle chassis belongs to the auto -parts field, and it is including round pin axle, the shaping of round pin axle one end has the diameter to be greater than the bulb of round pin axle, be equipped with the knuckle between bulb and the round pin axle, the toper cylinder of the round pin axle other end for dwindling gradually, the shaping of toper cylinder terminal surface has the connecting axle, the locating hole that coincides mutually with round pin axle center pin is all opened on connecting axle terminal surface and bulb top. The utility model discloses the bulb of structure is sold through setting up the bulb center after the locating hole comes assurance processing to accomplish and selling an axle center and do not squint to ensure to turn to portability and handiness in making its working process, in addition, the utility model discloses a cold extrusion one shot forming can be realized to bulb round pin, not only greatly reduced manufacturing cost, intensity is also very high moreover.
Description
technical field:
The utility model relates to technical field of automobile, particularly relates to a kind of car chassis ball end.
background technology:
Because ball end can rotate within the specific limits, effectively alleviate the internal force that space bar motion produces, so it is widely used in the field such as motor turning, suspension.
Ball end operationally sphere center position must overlap with bearing pin center shaft, not so ease of steering and manoevreability can directly be affected, and traditional ball end is due to the restriction of own form structure, normally make finished product by bar is carried out machinework through multiple lathe, the work efficiency of this mode is low, tooling cost is very high, and also have some to be processed into ball end finished product by being welded in by bulb on bearing pin, cause ball end bulb center and bearing pin axial line to produce deviation, and bulk strength is inadequate.
utility model content:
The purpose of this utility model is exactly to solve existing issue, and carry a kind of car chassis ball end, do not offset by arranging knock hole to ensure the ball end center after machining, ease of steering and manoevreability is guaranteed in working process, in addition, ball end of the present utility model can realize cold extruding one-shot forming, not only greatly reduces productive costs, and intensity is also very high.
Technology solution of the present utility model is as follows:
A kind of car chassis ball end, it includes bearing pin, described bearing pin one end forms the bulb that diameter is greater than bearing pin, knuckle is provided with between described bulb and bearing pin, the described bearing pin other end is diminishing tapered cylinders, described tapered cylinders end face forms adapter shaft, and described adapter shaft end face and bulb top all have the knock hole coincided with bearing pin center shaft.
As preferably, described bulb top is horizontal end face, and described knock hole takes shape on horizontal end face, and the ratio of the spacing H between described horizontal end face and the bulb centre of sphere and the diameter D of bulb is 2:5 ~ 9:20.
As preferably, the ratio of described bulb diameter D and pin diameter d is 8:5 ~ 9:5, and the radius between bulb and bearing pin is not less than 2mm.
As preferably, between described tapered cylinders and adapter shaft, be provided with chamfering, and the included angle A of described chamfering and horizontal surface is 55 ~ 65 °.
As preferably, the included angle B of described tapered cylinders outside face and horizontal surface is 16 ~ 19 °.
As preferably, the ratio of the spacing L between described bulb center and bearing pin and the diameter D of bulb is 2:5.
The beneficial effects of the utility model are:
The ball end of the utility model structure is by arranging knock hole, ensure that the bulb center after machining and bearing pin cental axial position do not offset, thus make to guarantee ease of steering and manoevreability in its working process, in addition, ball end structure proportion of the present utility model can realize cold extruding one-shot forming, not only greatly reduce productive costs, and intensity is also very high.
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
In accompanying drawing: 1, bearing pin; 2, bulb; 3, knuckle; 4, tapered cylinders; 5, adapter shaft; 6, knock hole; 7, chamfering.
detailed description of the invention:
As shown in Figure 1, a kind of car chassis ball end, it includes bearing pin 1, described bearing pin 1 one end forms the bulb 2 that diameter is greater than bearing pin 1, knuckle 3 is provided with between described bulb 2 and bearing pin 1, described bearing pin 1 other end is diminishing tapered cylinders 4, described tapered cylinders 4 end face forms adapter shaft 5, described adapter shaft 5 end face and bulb 2 top all have the knock hole 6 coincided with bearing pin 1 center shaft, by knock hole 6, ball end bulb center in Cold Extrusion Process is overlapped with remaining with bearing pin cental axial position, do not offset, improve Product Precision, wheel steering motor is made to have portability and manoevreability.
Particularly, described bulb 2 top is horizontal end face, described knock hole 6 takes shape on horizontal end face, the ratio of the spacing H between described horizontal end face and bulb 2 centre of sphere and the diameter D of bulb 2 is 2:5 ~ 9:20, conveniently can determine the position of knock hole 6 by arranging horizontal end face, bulb 2 arc surface can reduce the precision of knock hole 6 position.
Particularly, the ratio of described bulb 2 diameter D and bearing pin 1 diameter d is 8:5 ~ 9:5, and knuckle 3 radius between bulb 2 and bearing pin 1 is not less than 2mm, make the flowing power of the metal inside when cold extruding evenly mild, ratio between bulb 2 and bearing pin 1 too conference makes deformation quantity when extruding excessive, easily occurs cracking.
Particularly, between described tapered cylinders 4 and adapter shaft 5, be provided with chamfering 7, and described chamfering 7 is 55 ~ 65 ° with the included angle A of horizontal surface, make tapered cylinders 4 with can not be excessive with the flowing power of adapter shaft 5 interior metal when cold extruding, mould is stressed also to be reduced.
Particularly, the included angle B of described tapered cylinders 4 outside face and horizontal surface is 16 ~ 19 °, and it is too large, easy to crack that the included angle B of tapered cylinders 4 crosses deformation quantity when conference makes cold extruding.
Particularly, the ratio of the spacing L between described bulb 2 center and bearing pin 1 and the diameter D of bulb 2 is 2:5, if ratio is excessive or too smallly all can affect bulb 2 pivot angle operationally.
The foregoing is only preferred embodiment of the present utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the utility model protection.
