Description

Cooperating structure of automobile wheel rim and automobile half shaft flange

technical field

The utility model relates to the technical field of automobile transmission, in particular to a matching structure of an automobile wheel rim and an automobile half shaft flange.

Background technique

The half shaft of a car is a solid shaft that transmits torque between the differential and the drive wheel. Its inner end is generally connected to the half shaft gear through splines, and its outer end is connected to the rim through wheel bolts to transmit the torque generated by the engine. The weight of the car itself is also transferred to the rims via the half shafts. Wherein, the outer end of the half shaft is an automobile half shaft flange, which is assembled with the central hole of the rim.

Fig. 1 shows the assembly diagram of automobile wheel rim and automobile half-shaft flange in the prior art, and Fig. 2 is the local enlarged view of automobile wheel rim and automobile half-shaft flange fit place (i.e. the partial enlarged view in the dotted line frame in Fig. 1 ). As shown in Fig. 1 and Fig. 2, clearance fit is adopted between the central hole 3 of the automobile wheel rim 1 of the existing scenic light passenger vehicle type and the flange 2 of the automobile half shaft, and only the wheel bolts are used to transmit the weight of the whole vehicle and the generated energy of the engine. Torque makes the wheel bolts bear too much force and moment, which is prone to fracture and cause serious accidents.

Utility model content

(1) Technical problems to be solved

The utility model provides a matching structure between the automobile wheel rim and the automobile half-shaft flange, which is used to solve the problem that the half-shaft transmits the weight of the vehicle and the torque generated by the engine to the automobile rim only through the wheel bolts, so that the force and moment that the wheel bolts bear are too high. Large, prone to fracture problems.

(2) Technical solutions

In order to solve the above-mentioned technical problems, the utility model provides a matching structure between the automobile wheel rim and the automobile half-shaft flange, wherein, the center hole of the automobile rim and the automobile half-shaft flange are interference fit.

As for the matching structure between the automobile rim and the automobile half-shaft flange, preferably, the entire side wall of the automobile half-shaft flange is arranged in contact with the side wall of the central hole of the automobile rim.

As for the cooperation structure between the automobile wheel rim and the automobile half shaft flange, preferably, the central hole of the automobile wheel rim is a blind hole;

The end surface of the automobile half shaft flange is arranged in contact with the bottom surface of the central hole of the automobile wheel rim.

(3) Beneficial effects

The matching structure between the automobile rim and the automobile half-shaft flange provided by the utility model is the interference fit between the center hole of the automobile rim and the automobile half-shaft flange, so that the center hole of the automobile rim can bear part of the weight of the whole vehicle and the moment generated by the engine , reduce the force and moment of the wheel bolts, and solve the problem of fracture of the wheel bolts due to excessive force and moment. Moreover, this structure, which transmits force and moment jointly through the automobile half shaft flange and the wheel bolts, is more reliable and can effectively reduce the occurrence of accidents.

Detailed ways

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

Fig. 3 shows the assembling diagram of automobile wheel rim and automobile semi-axle flange in the embodiment of the present utility model; Fig. 4 shows the local enlarged view of the matching place of automobile wheel rim and automobile semi-axis flange in the embodiment of the present utility model (i.e. Partial enlarged view within the dotted box in Figure 3). As shown in Fig. 3 and Fig. 4, the matching structure of the automobile wheel rim and the automobile half-shaft flange in the embodiment of the present invention is that the center hole 3 of the automobile rim 1 and the automobile half-shaft flange 2 are an interference fit, so that the automobile rim The central hole 3 of 1 can bear part of the weight of the whole vehicle and the moment generated by the engine, reduce the force and moment on the wheel bolts, and solve the problem of fracture of the wheel bolts due to excessive force and moment. Moreover, this structure, which transmits force and moment jointly through the automobile half shaft flange and the wheel bolts, is more reliable and can effectively reduce the occurrence of accidents.

Preferably, the entire side wall of the automobile half shaft flange 2 is set in contact with the side wall of the central hole 3 of the automobile wheel rim 1, and the interference fit is used to increase the force-bearing area of the central hole 3, thereby increasing the bearing capacity of the central hole 3. reduce the force and moment on the wheel bolts.

In this embodiment, the central hole 3 of the automobile rim 1 can also be set as a blind hole, and the end face of the automobile half shaft flange 2 is set in contact with the bottom surface of the central hole 3 of the automobile rim 1, and the interference fit is used to further increase the central hole. 3 force area.

As can be seen from the above embodiments, the utility model adopts the cooperation structure of the automobile wheel rim and the automobile half-shaft flange provided by the utility model to be the interference fit between the center hole of the automobile rim and the automobile half-shaft flange, so that the automobile wheel rim The central hole can bear part of the weight of the vehicle and the moment generated by the engine, reducing the force and moment on the wheel bolts, and solving the problem of wheel bolts breaking due to excessive force and moment. Moreover, this structure, which transmits force and moment jointly through the axle shaft flange of the automobile and the wheel bolts, is more reliable and can effectively reduce the occurrence of accidents.

The above is only the preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and replacements can also be made. And replacement should also be regarded as the protection scope of the present utility model.
