The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Spoke type motor vehicle wheel of the present utility model, as shown in Figure 1, comprise wheel rim, wheel hub, spoke, spoke is arranged on to connect between wheel rim and the wheel hub and supports, spoke respectively with wheel rim on the female hole of bar and wheel hub on the spoke hole offered be connected, the utility model at first improves in the version of spoke itself, as shown in Figure 4, spoke is set to the angle of bending structure and the formation of bending back between 120-160 °, can make the spoke stand under load substantially all be in axial configuration, in theory: this angle angle is more big, and load-carrying capacity is more strong.Spoke of the prior art also is bending structure, as shown in Figure 5, angle after its bending is between 85-105 °, when surpassing under 105 ° the situation, can't be with the spoke netting, but net structure load-carrying capacity and impact resistance are all stronger, its reason is because the problem that spoke hole arranges on the one hand, also has the setting of the female hole site of bar, of the prior art female hole all is between left and right every setting, i.e. the first from left right side, said structure has determined the spoke bending angle of prior art between 85-105 °, the stand under load of spoke has only part to be in axial configuration; And the utility model increases the spoke angle, cooperate with the spoke hole direction of offering on the wheel hub, the spoke bending part places in the spoke hole near one side of pier nose fully, improve it and be subjected to force direction, and the female hole of bar is side distribution in twos, as shown in Figure 3, it is two on the left side, the right is two then, the left side is two again, the wide-angle bending of such respective outer side edges spoke, can well form the netting structure, the shape of wide-angle can change the stand under load direction at spoke pier nose position under the confined state, improve load-carrying capacity, the female hole of a bar side in twos distributes, making spoke that assembling not take place under the netting state interferes, can guarantee to have clearance distance between spoke and the spoke, clearance distance as shown in Figure 1, is thoroughly eliminated the horizontal increment load of spoke more than 1 millimeter, the arrangement of wheel rim and spoke simultaneously be connected the angle of bend of also having improved spoke pier nose position, enlarged the area of space between disc brake sheet and the spoke, the installation that clamps for disc brake provides enough spaces, has effectively avoided the interference of spoke and disc brake pincers, the loaded condition of outside spoke has been realized height balance coupling in making, and has realized the maximization of wheel load capacity.

In addition, the utility model has carried out thickening to the pier nose structure of spoke end and has handled, as shown in Figure 4 when improving spoked shape, pier nose is the force part, existing pier nose is flat structure, undertaken by a tapered slope stressed, easy fracture and loosening, and the utility model adds cylindrical structure with the pier nose structure, make pier nose more thick and heavy, can bear bigger load, promoted integral body and be subjected to loading capability.

In order to promote the load-carrying capacity of spoke, the utility model is realized further reinforcement by the moment of torsion that promotes between bar mother and the spoke, as shown in Figure 6, between bar mother and the spoke by antifriction composition (being the wear-resisting oil of existing corrosion-resistant steel), reduce the screw thread friction coefficient, strengthen the bar mother and cooperate with the moment of torsion of spoke.And in the prior art, by promoting the load-carrying capacity that moment of torsion promotes spoke, also do not occur, to those skilled in the art, there is not causal relationship between lifting moment of torsion and the load-carrying capacity, this is the outstanding innovative point of the utility model.

Further in the scheme, in order to solve the founding property of wheel hub, the utility model wheel hub is provided with lightening hole, as shown in Figure 2, namely on the wheel hub of spoke dish both sides, offer a plurality of holes, reduced material on the one hand, in addition, the wall thickness of wheel hub is reduced, can cool off fast in processing, its interior tissue crystal property is optimized, and makes its structure more fine and close.

In the process of wheel assembling, the end that spoke has a screw thread passes with bar female thread on the wheel rim from spoke hole and is connected, pier nose places an end of spoke hole, in order better to determine position and the direction of spoke hole and to process more convenient, we offer the reservation pit in advance in the position of each spoke hole, determine the center-point of spoke hole, and reserved the be more convenient for processing of spoke hole of pit, the use of in easy to process, also having saved material.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
