Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a front subframe that facilitates the assembly of a swing arm. Background Technology

[0002] In traditional automotive chassis design, the subframe, as an auxiliary device, connects the suspension to the body, enabling the integrated assembly and disassembly of suspension components and greatly promoting the modular and platform-based development of automotive chassis. The subframe design frees the suspension system from direct constraints by the body structure, thereby improving overall vehicle comfort and handling. However, existing methods of connecting the front subframe to the control arm primarily present the following two problems:

[0003] The enclosed cavity and the U-shaped opening are assembled in the same direction:

[0004] Both the front and rear points of the swing arm are closed cavities, and the front subframe provides a corresponding U-shaped opening adapter, which is fastened by Z-direction bolts.

[0005] While this method offers flexible assembly, it lacks clear assembly positioning, resulting in laborious and time-consuming centering during the assembly process.

[0006] "Dog bone" style connection:

[0007] The front and rear points of the swing arm are aligned with the front subframe in the Z-direction, and then secured with bolts.

[0008] This method also suffers from unclear assembly positioning, which increases assembly difficulty and time.

[0009] To address the problems existing in the prior art, this invention designs a front subframe and swing arm front and rear embedded assembly structure, aiming to improve assembly efficiency and accuracy. Utility Model Content

[0010] To address the shortcomings of existing technologies, this utility model provides a front subframe that facilitates the assembly of the swing arm, solving the problem that the existing connection method between the front subframe and the swing arm lacks clear assembly positioning, resulting in laborious and time-consuming centering during the assembly process.

[0011] To achieve the above objectives, this utility model provides the following technical solution: a front subframe for easy assembly of a swing arm, comprising:

[0012] The frame body has a U-shaped opening and a closed cavity on its side.

[0013] The swing arm body has a swing arm closed cavity at one end and a swing arm U-shaped opening at the other end.

[0014] During the assembly process, when the front end of the swing arm main body is inserted into the frame U-shaped opening of the frame main body, the swing arm U-shaped opening at the rear end of the swing arm main body and the frame closed cavity of the frame main body form a virtual positioning.

[0015] Preferably, the swing arm closed cavity is provided with a through first through hole, and the frame U-shaped opening is provided with a through first mounting hole, and the first through hole is adapted to the first mounting hole.

[0016] Preferably, when the swing arm closed cavity is inserted into the U-shaped opening of the frame, the side of it away from the U-shaped opening of the swing arm abuts against the outer wall of the frame body, and the first through hole is connected to the first mounting hole.

[0017] Preferably, the first through hole and the first mounting hole are connected by bolts.

[0018] Preferably, the U-shaped opening of the swing arm has a through second mounting hole, and the closed cavity of the frame has a through second through hole, and the second mounting hole and the second through hole are adapted to each other.

[0019] Preferably, when the U-shaped opening of the swing arm is sleeved on the closed cavity of the vehicle frame, the side of the swing arm away from the closed cavity abuts against the outer wall of the main body of the vehicle frame, and the second mounting hole is connected to the second through hole.

[0020] Preferably, the second mounting hole and the second through hole are connected by bolts.

[0021] This utility model discloses a front subframe that facilitates the assembly of a swing arm, and its beneficial effects are as follows:

[0022] 1. This front subframe, designed for easy assembly of the swing arm, breaks away from the traditional design concept of assembling the front subframe and swing arm in the same direction. It innovatively employs a reverse-alignment assembly structure. During assembly, when the swing arm's enclosed cavity is inserted into the U-shaped opening of the frame, the side furthest from the U-shaped opening abuts against the outer wall of the frame body. Conversely, when the U-shaped opening is fitted onto the enclosed cavity, the side furthest from the enclosed cavity abuts against the outer wall of the frame body. This achieves virtual positioning between the swing arm and the frame body. This virtual positioning design prevents misalignment of the front and rear points of the swing arm during assembly, reducing assembly difficulty. It improves assembly accuracy and reliability, and reduces rework and repair costs caused by assembly errors. Furthermore, the use of Z-direction bolts for both the front and rear points of the swing arm facilitates the standardization of assembly tooling.

[0023] 2. The front subframe for easy assembly of the swing arm, when the swing arm enclosed cavity is inserted into the U-shaped opening of the frame, the first through hole is connected to the first mounting hole, so that the first through hole and the first mounting hole can be connected by bolts. When the swing arm U-shaped opening is sleeved on the enclosed cavity of the frame, the second mounting hole is connected to the second through hole, so that the second mounting hole and the second through hole can be connected by bolts.

[0032] The swing arm body 1 has a swing arm closed cavity 11 at one end and a swing arm U-shaped opening 12 at the other end.

[0033] During the assembly process, when the swing arm closed cavity 11 at the front point of the swing arm body 1 is embedded into the frame U-shaped opening 21 of the frame body 2, virtual positioning is formed by the swing arm U-shaped opening 12 at the rear point of the swing arm body 1 and the frame closed cavity 22 of the frame body 2.

[0034] Breaking away from the traditional design concept of unidirectional assembly of the front subframe and swing arm, this innovative design employs a forward and reverse assembly structure. During assembly, when the swing arm's enclosed cavity 11 is inserted into the frame's U-shaped opening 21, its side away from the U-shaped opening 12 abuts against the outer wall of the frame body 2. When the swing arm's U-shaped opening 12 is fitted onto the frame's enclosed cavity 22, its side away from the enclosed cavity 11 abuts against the outer wall of the frame body 2. This achieves virtual positioning between the swing arm body 1 and the frame body 2. This virtual positioning design prevents misalignment of the front and rear points of the swing arm body 1 during assembly, reducing assembly difficulty. It improves assembly accuracy and reliability, and reduces rework and repair costs caused by assembly errors. Since both the front and rear points of the swing arm are secured with Z-direction bolts, it facilitates the standardization of final assembly tooling equipment.

[0036] Specifically disclosed, when the swing arm closed cavity 11 is inserted into the frame U-shaped opening 21, the side of it away from the swing arm U-shaped opening 12 abuts against the outer wall of the frame body 2, and the first through hole 111 is connected to the first mounting hole 211.

[0037] Furthermore, the first through hole 111 and the first mounting hole 211 are connected by bolts.

[0038] Specifically disclosed, the U-shaped opening 12 of the swing arm has a through second mounting hole 121, and the closed cavity 22 of the frame has a through second through hole 221, and the second mounting hole 121 and the second through hole 221 are adapted to each other.

[0039] Specifically disclosed, when the U-shaped opening 12 of the swing arm is fitted onto the closed cavity 22 of the frame, the side of it away from the closed cavity 11 of the swing arm abuts against the outer wall of the frame body 2, and the second mounting hole 121 is connected to the second through hole 221.

[0040] Furthermore, the second mounting hole 121 and the second through hole 221 are connected by bolts.

[0041] When the swing arm closed cavity 11 is inserted into the frame U-shaped opening 21, the first through hole 111 is connected to the first mounting hole 211, so that the first through hole 111 and the first mounting hole 211 can be connected by bolts. When the swing arm U-shaped opening 12 is sleeved on the frame closed cavity 22, the second mounting hole 121 is connected to the second through hole 221, so that the second mounting hole 121 and the second through hole 221 can be connected by bolts.
