Description
Technical field
The utility model belongs to a kind of auto parts and components, relates generally to a kind of Kazakhstan hand controller of strengthening design.
Background technology
It is the part being used cooperatively with the assembling of first and second generation automobile hub bearing to breathe out hand controller；Directly play connection wheel and
The effect of bearing capacity between vehicle body, while the fillet R for breathing out hand controller is also the region that bearing stress is most concentrated；Such Kazakhstan bar at present
The axle journal of head is single external cylindrical surface, and external cylindrical surface and chamfering R are after coarse-fine vehicle, using grinding final molding；
The roughness of mill processing is generally Ra0.6~0.8 or so；(note：Material surface roughness is smaller, and stress concentration is smaller, tired
Intensity is also higher).
Invention content
The purpose of this utility model is to provide a kind of Kazakhstan hand controllers of strengthening design, and the axle journal position for breathing out hand controller is designed to
Diameter different Bicylindrical Surface D2, D3；It is unaffected when ensureing front end external cylindrical surface D3 with hub-bearing unit combined riveting
Under the premise of, improve bearing strength when breathing out hand controller and hub-bearing unit assembling use.
To achieve the above object, technical solution provided by the utility model is：A kind of Kazakhstan hand controller of strengthening design, Ha Ba
Head is made of inner flange, boss bolt, and the ring flange edge of inner flange is equipped with multiple boss bolts, the ring flange one of inner flange
Short end axle journal has been extended to form at the center of side, has been extended with the first cylindrical section, at the ring flange opposite side center of inner flange successively
Two cylindrical sections, third cylindrical section, the diameter of the first cylindrical section are more than the second cylindrical section, and the diameter of the second cylindrical section is justified more than third
Shell of column, and for arc rounding off between the first cylindrical section and the ring flange of inner flange, the second cylindrical section and the first cylindrical section
Connecting portion is equipped with the reinforcing strip of arc, and reinforcing strip uses the groove that rolling tool revolving-rolling is formed.
The center line of short end axle journal and the center line of inner flange is located along the same line.
The boss bolt is five, is uniformly distributed along inner flange center line.
Second cylindrical section, the diameter difference range of third cylindrical section cylinder are 0.1mm≤(D2-D3)≤5mm；Second
A diameter of 20~the 80mm of cylindrical section.
The reinforcing strip axial depth a=0.01~0.3mm, radial depth b=0.01~0.3mm.
The main effect of the utility model is：Such Kazakhstan hand controller axle journal at present is designed to for the shape of single external cylindrical surface
The Bicylindrical Surface of difference cooperation diameter；So as to unaffected when ensureing front end external cylindrical surface with hub-bearing unit combined riveting
Under the premise of, bearing strength when breathing out hand controller and hub-bearing unit assembling use can be improved.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is reinforcing strip axially and radially depth schematic diagram.
Specific embodiment
With reference to all attached drawings, the utility model is described in further detail, and the preferred embodiment of the utility model is：Ginseng
See attached drawing 1 and attached drawing 2, a kind of Kazakhstan hand controller of strengthening design described in the present embodiment breathes out hand controller by inner flange 1,2 structure of boss bolt
Into the ring flange edge of inner flange 1 is equipped with multiple boss bolts 2, and boss bolt 2 is five, uniform along 1 center line of inner flange
It is distributed, short end axle journal, center line and the inner flange 1 of short end axle journal has been extended to form at the ring flange side center of inner flange 1
Center line is located along the same line, and is extended with the first cylindrical section D1, the second circle at the ring flange opposite side center of inner flange 1 successively
Shell of column D2, third cylindrical section D3, the first cylindrical section D1 diameter be more than the second cylindrical section D2, the diameter of the second cylindrical section D2 is more than
Third cylindrical section D3, and be arc rounding off between the first cylindrical section D1 and the ring flange of inner flange 1, second cylinder
Section D2, third cylindrical section D3 cylinders diameter difference range be 0.1mm≤(D2-D3)≤5mm；Second cylindrical section D2 is a diameter of
Reinforcing strip of the connecting portion of 50mm, the second cylindrical section D2 and the first cylindrical section D1 equipped with arc, reinforcing strip axial depth a=
0.15mm, radial depth b=0.15mm, reinforcing strip use the groove that rolling tool revolving-rolling is formed.Reinforcing strip is using special
Rolling depression cutter the technique without machining is carried out on numerically-controlled machine tool, be effectively improved breathe out hand controller fillet roughness, it is coarse
Degree can reach Ra0.2 μm or so；Surface compress residual stresses are generated after rolling simultaneously, surface peening layer is formed, it is hard to improve its surface
Degree, so as to effectively improve the tired bearing strength for breathing out hand controller.After breathing out hand controller rolling and processing, it can no longer need to do grinding；
So as to reduce processing cost, production efficiency is improved.The main effect of the present embodiment is：It is by such Kazakhstan hand controller axle journal at present
The shape of single external cylindrical surface is designed to the Bicylindrical Surface of different cooperation diameters；So as to ensure the same wheel hubs of front end external cylindrical surface D3
During bearing unit combined riveting it is unaffected under the premise of, can improve breathe out hand controller and hub-bearing unit assembling use when carrying
Intensity.
The embodiment of the above is only the preferred embodiment of the utility model, and the reality of the utility model is not limited with this
Apply range, therefore the variation that all shape, principles according to the utility model are made, it should all cover in the scope of protection of the utility model
It is interior.
