[0016] In the description of the present application, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and the above description is simplified for the convenience of describing the present application, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0017] The singular forms "a", "said", and "the" used in the description are intended to include plural forms unless clearly specified to the contrary. The terms "comprise", "include" and "contain" used in the description mean that the claimed features exist, but do not exclude the existence of one or more other features. In the description, when an element is referred to as being "on", "fixed to", "connected to", "joined to" or the like another element, the element can be directly on, fixed to, connected to, joined to or in contact with the other element, or there can be an intermediate element.

[0018] It can be understood that although the terms "first", "second" and the like can be used herein to describe different elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. Therefore, the first element can be referred to as the second element without departing from the teachings of the present application.

[0019] The exemplary embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood, however, that the present application can be presented in various ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all the drawings, the same reference numerals represent the same or functionally similar elements.

[0020] Figure 1 and Figure 2The balanced bearing hub is shown from both sides, mainly composed of a pair of first half hub 1 and second half hub 2 spliced by aluminum alloy liquid forging process, the aluminum alloy balanced bearing hub made by this process has the characteristics of light weight, which helps the vehicle to achieve lightweight improvement. Because the overall weight of the balanced bearing hub is lighter, its structure needs to be redesigned from the overall consideration to balance the connection strength and forming feasibility.

[0021] The transmission shaft hole 10 for sleeving the outer periphery of the transmission shaft is located between the first half hub 1 and the second half hub 2, and the bearing ring (not shown in the figure) is arranged in the transmission shaft hole 10. The axle mounting hole 30 for directly fixing and connecting with the automobile axle is opened outward on the side of the first half hub 1, and the axis of the axle mounting hole 30 is perpendicular to the axis of the transmission shaft hole 10. The axle mounting hole 30 is the positioning reference of the entire balanced bearing hub, and the positional relationship with the transmission shaft hole 10 makes the balanced bearing hub always stable during the working process of the transmission shaft. A pair of hollow structures 31 are arranged on both sides of the axle mounting hole 30, which is beneficial to the forming of the axle mounting hole 30 and prevents the low-density cavity caused by the opening on the flat surface from causing quality defects in the die casting process.

[0022] The entire balanced bearing hub is fixed on the mounting bracket through the bracket mounting hole 20 between the first half hub 1 and the second half hub 2, and then assembled to the axle. The bracket mounting hole 20 is arranged at the four corners of the first half hub 1 and the second half hub 2, and the distance from each bracket mounting hole 20 to the axle mounting hole 30 is equal.

[0023] Combined with reference Figure 3 The first half hub 1 and the second half hub 2 are specifically fastened and fixed by a pair of half hub fixing holes 40, which are respectively located on both sides of the first half hub 1 and the second half hub 2 and between the bracket mounting holes 20. The half hub fixing hole 40 is provided with a threaded structure 40a, so that the first half hub 1 and the second half hub 2 are locked and fixed by the threaded part before being fixed on the bracket.

[0024] In a preferred embodiment, the first half hub 1 and the second half hub 2 are made of aluminum alloy material with model A356. In the 90% die casting state, the full piece filling is realized at a pressure of 80-100 Mpa.
