Description

Technical Field

[0001] This utility model relates to the field of motorcycle frame technology, and in particular to a motorcycle aluminum alloy frame. Background Technology

[0002] In the motorcycle manufacturing industry, the frame is a core component, bearing the mechanical support and structural integration function of the entire vehicle. Traditional motorcycle frames are mostly made of steel, which has a certain strength, but also has drawbacks such as large weight and easy corrosion. This increases the curb weight of the motorcycle, affects handling performance and fuel economy, and shortens the service life of the frame.

[0003] Currently, aluminum alloy is the preferred material for motorcycle frames. However, aluminum alloy frames have low modular integration, and the assembly of various components is cumbersome, which is not conducive to improving production efficiency and subsequent maintenance and repair. Utility Model Content

[0004] The purpose of this utility model is to provide a motorcycle aluminum alloy frame, which aims to solve the problems of low modular integration, cumbersome assembly of various components, and the resulting difficulties in improving production efficiency and subsequent maintenance and repair in the current aluminum alloy frame technology.

[0005] To achieve the above objectives, this utility model provides a motorcycle aluminum alloy frame, including a main support frame, two symmetrical booms, a first connecting arm, a second connecting arm, and a connecting assembly. The two symmetrical booms are respectively connected to the main support frame. The first connecting arm is detachably connected to the two symmetrical booms and is located between the two symmetrical booms. The second connecting arm is detachably connected to the two symmetrical booms and is located between the two symmetrical booms. The connecting assembly is connected to the symmetrical booms.

[0006] The connecting assembly includes a lug plate and a diagonal brace. The lug plate is detachably connected to the symmetrical boom and is located on one side of the symmetrical boom. The diagonal brace is detachably connected to the lug plate and is located on one side of the lug plate.

[0007] The motorcycle aluminum alloy frame also includes multiple mounting studs, which are fixedly connected to the main support frame and located on the outer side wall of the main support frame.

[0008] The motorcycle aluminum alloy frame also includes a connecting bracket, which is fixedly connected to the symmetrical boom and located on one side of the symmetrical boom.

[0009] The symmetrical boom has trapezoidal mounting holes.

[0010] This utility model discloses a motorcycle aluminum alloy frame. The frame is centered on a main support frame, with symmetrical arms extending symmetrically on both sides to form a balanced load-bearing foundation. The first and second connecting arms are connected to the symmetrical arms via a detachable structure, enhancing lateral stiffness and facilitating assembly and maintenance. The connecting components are integrated onto the symmetrical arms, with standardized interfaces for adapting to power, suspension, and other systems, supporting modular integration. Simultaneously, lightweight designs such as hollowing and topology optimization are employed to reduce weight while strengthening stress concentration areas. Through the integration of a symmetrical structure, detachable connections, functional interfaces, and lightweight strategies, the design balances structural strength, assembly flexibility, and performance expandability.
