Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a die-cast aluminum housing with a special-shaped transmission gear for new energy vehicles. Background Technology

[0002] The die-cast aluminum housing of new energy vehicles is a key component in the vehicle's transmission system. It integrates transmission gears and other transmission functional components such as the drive shaft into a whole, maintaining their correct positions and transmitting power in a coordinated manner according to a certain transmission relationship.

[0003] However, the existing die-cast aluminum housings for new energy vehicles have poor heat conduction, making it difficult to dissipate heat from the transmission components inside the housing in a timely manner, resulting in low heat dissipation efficiency.

[0004] To address these issues, we propose a die-cast aluminum housing with irregularly shaped transmission teeth for new energy vehicles. Utility Model Content

[0005] The purpose of this utility model is to provide a die-cast aluminum housing with irregularly shaped transmission teeth for new energy vehicles, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A die-cast aluminum housing for a transmission gear in a new energy vehicle includes a housing with several shaft holes. Each shaft hole has interconnected circumferential cooling pipes and several radial cooling pipes on its outer surface. The radial cooling pipes are distributed on the housing surface between the circumferential cooling pipes and the shaft holes. Adjacent circumferential cooling pipes are connected by a connecting pipe, which is equipped with an inlet connector and an outlet connector. The housing inside the shaft hole has a cooling ring groove, which is connected to the radial cooling pipes by the connecting groove.

[0008] In a further embodiment, the circumferential cooling pipes coincide with the axis of the shaft hole, the axis of each radial cooling pipe passes through the central origin of the shaft hole, and the radial cooling pipes are symmetrically distributed along the axis of the shaft hole.

[0009] In a further embodiment, the cooling ring grooves are spaced apart along the axis of the shaft hole, and adjacent cooling ring grooves are connected by a number of through holes.

[0010] In a further embodiment, the outer periphery of the housing is provided with a plurality of heat dissipation ribs, and the heat dissipation ribs are parallel to the axial direction of the shaft hole.

[0011] In a further embodiment, a number of reinforcing ribs are evenly provided at the right-angle bend between the housing and the shaft hole, and the reinforcing ribs are symmetrically distributed along the center line of the shaft hole.

[0012] In a further embodiment, the reinforcing rib adopts a right-angled triangle structure, and the two right-angled sides of the reinforcing rib are respectively connected to the inner wall of the box and the outer wall of the shaft hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model features circumferential cooling pipes, radial cooling pipes, and connecting pipes laid on the surface of the housing. By circulating coolant between the pipes, the outer side of the housing can be cooled, thereby improving the heat transfer efficiency of the inner and outer sides of the housing. This facilitates timely heat dissipation for the transmission components inside the housing. Furthermore, the cooling ring grooves can improve the cooling effect at the shaft hole, thereby improving the heat dissipation efficiency of the transmission shaft installed in the shaft hole.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 A die-cast aluminum housing for a transmission gear in a new energy vehicle includes a housing 1, which is die-cast from aluminum alloy. The housing 1 has several shaft holes 2, one end of which protrudes from the inner surface of the housing 1 to increase its surface area, facilitating better installation and connection with the transmission shaft. Each shaft hole 2 has interconnected circumferential cooling pipes 3 and several radial cooling pipes 4 on its outer surface. The radial cooling pipes 4 are distributed on the surface of the housing 1 between the circumferential cooling pipes 3 and the shaft holes 2. The centerlines of the circumferential cooling pipes 3 and the shaft holes 2 coincide. Each radial cooling pipe 4 has its axis passing through the center origin of the shaft hole 2, and the radial cooling pipes 4 are symmetrically distributed along the axis of the shaft hole 2. Adjacent circumferential cooling pipes 3 are connected by a connecting pipe 5, and the connecting pipe 5 is equipped with an inlet connector 6 and an outlet connector 7. The inlet connector 6 and the outlet connector 7 are used to connect to an external coolant supply device, so that the coolant can circulate inside the circumferential cooling pipes 3, radial cooling pipes 4 and connecting pipe 5, so as to quickly cool the box 1, improve the heat conduction effect of the box 1, and facilitate timely heat dissipation for the transmission components inside the box 1.

[0024] The housing of the shaft hole 2 is provided with a cooling ring groove 21, and the cooling ring groove 21 is connected to the radial cooling pipe 4 through a connecting groove 22, so that the coolant can flow through the interior of the cooling ring groove 21, which facilitates the cooling of the section where the shaft hole 2 is located, thereby improving the heat dissipation efficiency of the drive shaft installed in the shaft hole 2.

[0025] Furthermore, considering that the strength of the section of the shell where the shaft hole 2 is located is low when it is completely hollow, several cooling ring grooves 21 are provided at intervals along the axis of the shaft hole 2, and adjacent cooling ring grooves 21 are connected by several through holes 23, thereby ensuring the strength of the section where the shaft hole 2 is located.

[0026] The outer periphery of the housing 1 is provided with several heat dissipation ribs 8, and the heat dissipation ribs 8 are parallel to the axial direction of the shaft hole 2. The heat dissipation ribs 8 can not only expand the heat dissipation area on the side of the housing 1 and improve the heat dissipation efficiency, but also strengthen the strength of the side of the housing 1.

[0027] Several reinforcing ribs 9 are evenly provided at the right-angle bend between the housing 1 and the shaft hole 2. The reinforcing ribs 9 are symmetrically distributed along the center line of the shaft hole 2. The reinforcing ribs 9 adopt a right-angled triangular structure, and the two right-angled sides of the reinforcing ribs 9 are connected to the inner wall of the housing 1 and the outer wall of the shaft hole 2, respectively, to further improve the strength of the section where the shaft hole 2 is located.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
