Description

Technical Field

[0001] The present application belongs to the field of new energy vehicle technology, and more specifically, relates to a forged single- and double-motor fork structure. Background Art

[0002] With the increasing global attention to environmental protection and sustainable development, new energy vehicles, as a green and environmentally friendly means of transportation, have received widespread attention and application. As a key component in the gearbox of new energy vehicles, the performance of the fork structure directly affects the driving experience and operating efficiency of the vehicle. The gearbox body and motor in new energy vehicles are often combined into one, with a compact structure. Conventional fork structures are single fork structures and then axially connected through a connecting shaft, so they occupy a large space and have many processing steps. They are not compatible with the structural requirements of the current new energy vehicle transmission device. Therefore, it is necessary to solve the above technical problems. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a forged single- and double-motor fork structure to solve the technical problems of the prior art.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is: to provide a forged single- and double-motor fork structure, including:

[0005] The head is a columnar structure;

[0006] A first plate connected to the head and perpendicular to the axial direction of the head, the first plate extending in two intersecting directions away from the head and symmetrically arranged;

[0007] A second plate is connected to an end of the first plate away from the head and is located in the same plane as the first plate, and an end of the second plate away from the first plate forms a semicircular fork;

[0008] Fork legs formed at both ends of the fork and extending along the thickness direction of the second plate;

[0009] A middle boss is formed on the second plate and extends in the same direction as the fork legs. The extension height of the middle boss is the same as the extension height of the fork legs.

[0010] Optionally, a connecting arc is provided between the two parts from which the first plate extends respectively.

[0011] Optionally, the middle boss is adjacent to the contour edge of the fork opening and is located between the two fork legs.

[0012] Optionally, the fork legs and the middle boss are both symmetrically arranged relative to the second plate.

[0013] Optionally, the first plate is thicker than the second plate.

[0014] Optionally, a first depression recessed along a thickness direction of the first plate is provided at an end of the first plate close to the second plate.

[0015] Optionally, a second depression recessed along a thickness direction of the first plate is provided at an end of the first plate close to the head.

[0016] Optionally, the second recess is symmetrical about a symmetry center line of the first plate.

[0017] Optionally, the fork leg is provided with a lug radially away from the fork leg along the fork opening.

[0018] Optionally, the forged single-double motor fork structure further includes a protrusion connected to the first plate, and the protrusion and the head extend in opposite directions relative to the first plate.

[0019] The beneficial effect of the forged single-double motor fork structure provided in the present application is that: compared with the prior art, the fork structure in the present application has a first plate extending in two intersecting directions and a second plate connected to the end of the first plate, and the second plate is provided with a fork foot and an intermediate boss extending in the direction of its own thickness. Since the intermediate boss and the fork foot have the same extension height, when the forged single-double motor fork structure provided in the present application is connected to the object structural part, the intermediate boss can cooperate with the fork foot and the object part to form three abutment positions distributed in a triangle, thereby significantly improving the transmission stability of the fork structure and the object part in the present application, and having a reliability far superior to the prior art. In addition, the first plate in the present application extends in two directions away from the column, which can be adapted to the reduction box structure driven by a single motor or a double motor, and has a wider range of applications; at the same time, the two first plates and the corresponding fork feet share a head, so that the fork has a flat structure, which can effectively reduce the axial size, meet the needs of compact gearboxes, reduce the number of processing links and parts, and help save costs.

Since the intermediate boss 106 and the fork foot 105 have the same extension height, when the forged single-double motor fork structure provided in the present embodiment is connected to the object structural part, the intermediate boss 106 can cooperate with the fork foot 105 and the object part to form three abutment positions distributed in a triangular shape, thereby significantly improving the transmission stability of the fork structure and the object part in the present embodiment, and having a reliability far superior to that of the prior art. In addition, in the present embodiment, the first plate 102 extends in two directions away from the column, and can be adapted to a single-motor driven or dual-motor driven reduction gearbox structure, having a wider range of applications; at the same time, the two first plates 102 and the corresponding fork legs 105 share a head 101, so that the shift fork has a flat structure, which can effectively reduce the axial size, meet the needs of compact gearboxes, reduce the number of processing links and related connecting parts and other components, and is conducive to cost savings; the one-piece forging has good strength and rigidity.
