Compared with the prior art, the probability of deformation of the cone face of the steel insert type hub when the framework main body is cast, the stability of the cone face is good, a projection face in a Z direction in the framework main body of the spline part is added, and accordingly the performance of hub pushing-out force is improved, the structure of the hub is simpler than that of a traditional steel insert type hub, machining amount is smaller, machining cost is lower, the spline part is still made of traditional steel materials, the intensity of the spline part is improved, the improved steering wheel hub is suitable for a steering wheel with spline teeth with a number of less than 60, and an application range is expanded.
Description
Technical field
The utility model relates to the Die Lenkradnabeals Pralltopf ausgebildet technical field, specifically a kind of improved Die Lenkradnabeals Pralltopf ausgebildet.
Background technology
Bearing circle is the steering operation device of power actuated vehicle.Referring to Fig. 1, reliable between bearing circle 4 and the tubing string 5 is connected the successful transmission that has guaranteed steering torque, is one of prerequisite critical function of bearing circle.Be being connected of bearing circle and tubing string to realize by the wheel hub that is positioned at the bearing circle center.Referring to Fig. 2 and Fig. 3, usually the wheel hub at bearing circle center comprises skeleton main body and hub body, wherein the first half of hub body is made as spline part, namely vertically establish columniform axis hole at the first half of hub body, and establish the spline part that spline 6 forms hub body at this columniform axis hole inside face, the inside of the lower part of hub body is provided with taper hole 2, and the inwall of taper hole 2 has also namely formed the conical surface 7 of wheel hub, and the aperture of the narrow end of the taper hole 2 of joining place is greater than the aperture of axis hole bottom axis hole.Wherein, spline part has been born the function of bearing circle 4 to tubing string 5 transmitting torques, the location that the conical surface 7 is realized bearing circle Z-direction on tubing string.Common wheel hub has at present: referring to Fig. 4, integral die-cast formula wheel hub at the magnesium/aluminum alloy material of skeleton main body 1 interior integrated die-casting moulding, and referring to Fig. 2 and Fig. 3, the independently steel built-in type hub body that steel matter is made, during use in its outside again die casting skeleton main body 1 form steel built-in type wheel hub.Wherein, one, the advantage of steel built-in type wheel hub is that steel matter is hard, goes for the number of teeth and is less than 60 spline, the less number of teeth just can be passed to torsion on the tubing string by bearing circle; And the inferior position of steel built-in type wheel hub has: 1, the conical surface size of steel built-in type wheel hub easily distortion and overproof in the process of its outside die casting skeleton main body; 2, in order to guarantee the Joint strenght of steel built-in type hub body and skeleton main body, steel built-in type hub body outside needs to be designed with anti-rotation and the structure that prevents axial jump, and this needs more design space, has promoted the design difficulty of steel built-in type wheel hub; 3, increase independently steel built-in type hub body, skeleton main body cost obviously increases.Two, the advantage of integral die-cast formula wheel hub is: without the steel inserts, cost is lower; Conical surface one-step die casting, good stability of the dimension; The shortcoming of integral die-cast formula wheel hub is: because magnesium aluminum alloy intensity is lower, usually be only applicable to spline tooth number greater than 60 bearing circle.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, spline part and the conical surface is arranged apart on two parts, spline part still keeps traditional steel material, can be equally applicable to spline tooth number and be less than 60 bearing circle, has effectively guaranteed the transmission of bearing circle torsion to tubing string; The conical surface then is shaped in the skeleton main body when the die casting of skeleton main body, has avoided the possibility of conical surface deformation, promotes conical surface dimensional stability.
For achieving the above object, design a kind of improved Die Lenkradnabeals Pralltopf ausgebildet, comprise skeleton main body, spline part, the conical surface, it is characterized in that: spline part and the conical surface are split type, spline part is made as independently steel inserts, bottom in the skeleton main body is provided with taper hole, and taper hole forms the conical surface at the inwall of skeleton main body, is embedded the steel inserts in the skeleton main body on taper hole top.
The axis hole of described spline part and taper hole are positioned on the same axially bored line.
The utility model is compared with prior art, has following advantage:
One, compare with conventional steel built-in type wheel hub: the conical surface is shaped in the skeleton main body when the die casting of skeleton main body, has avoided the possibility of steel built-in type wheel hub conical surface deformation when die casting skeleton main body, promotes conical surface dimensional stability, conical surface good stability; Spline part is made independently inserts form, can be used as individual part and is applied in other applicable skeleton main bodys, and be not subjected to the conical surface to change restriction; Increase the projecting plane of spline part Z-direction in the skeleton main body, thereby promoted the performance of wheel hub ejecting force; Hub length size and weight reduce near half, can make approximately 30g of bearing circle loss of weight; , amount of machining simpler than conventional steel built-in type wheel hub structure still less, tooling cost is lower;
Two, compare with traditional integral pressure-casting type wheel hub: spline part has still kept traditional steel material, has promoted spline part intensity, is applicable to spline tooth number and is less than 60 bearing circle, has enlarged the product applicable surface, and has effectively guaranteed the transmission of bearing circle torsion to tubing string.

The specific embodiment
Now the utility model is further described by reference to the accompanying drawings.
In the utility model the spline part of original steel built-in type wheel hub is made separately steel inserts 3, referring to Fig. 5, and design a skeleton die casting, and after in the skeleton die casting, arranging suitable inserts locating surface, steel inserts 3 is put into the skeleton die casting carry out die casting, die-casting material can aluminium/magnesium alloy materials, after die casting is finished, just can be at steel inserts 3 profile skeletonization frame bodies 1, and skeleton main body 1 interior formation taper hole 2 that can be below steel inserts 3 during die casting, also namely at the skeleton main body 1 interior formation conical surface 7, the axis hole of this taper hole 2 and steel inserts 3 is positioned on the same axially bored line, referring to Fig. 6.
The utility model combines the advantage of original steel built-in type wheel hub and integral die-cast formula wheel hub like this, can satisfy number of teeth requirement for spline part material hardness when less, that can avoid again that the conical surface of steel built-in type wheel hub produces deformation when die casting skeleton main body may.Can increase the projecting plane of spline part Z-direction in the skeleton main body simultaneously, thereby promote the performance of wheel hub ejecting force.
