Motorcycle frame and motorcycle

Abstract

The invention discloses a motorcycle frame and a motorcycle. The rear end of a lower-left-front main beam and the rear end of a lower-right-front main beam of the motorcycle frame extend backwards tointersect correspondingly to form a first connecting part, the portion, close to the lower portion, of a lower-left-rear main beam and the portion, close to the lower portion, of a lower-right-rear main beam form second connecting parts correspondingly, third connecting parts are further arranged on the positions, at the lower-left-rear main beam and the lower-right-rear main beam, of the lower portions of the second connecting parts, and fourth connecting parts are arranged at the lower end of a left vertical beam and the lower end of a right vertical beam. According to the motorcycle frame and the motorcycle, an engine and the motorcycle frame bear the external load together and counteract a bending moment generated by the load of the engine and the motorcycle frame, thus, the width sizeof a main bearing beam of the motorcycle frame can be reduced, the weight is lowered and the occupied space is narrowed, meanwhile, the bearing capability can be improved or compared with the prior art, the bearing capability is not reduced, the safety of the motorcycle is ensured, the motorcycle frame is suitable for all motorcycles including large-discharge-capacity motorcycles, so that the motorcycle weight is lowered, the motorcycle energy consumption is reduced, and environmental protection and energy saving are facilitated.

Description

technical field [0001] The invention relates to a motorcycle component and a motorcycle, in particular to a motorcycle frame and the motorcycle. Background technique [0002] In the prior art, the motorcycle frame is the main load-bearing part of the motorcycle, and for the motorcycle, the main component to be carried is the motorcycle engine. The installation of the motorcycle engine is mainly suspended on the frame, and the frame carries its main weight, plus the weight of other equipment and components, which puts forward higher requirements for the load-bearing capacity of the frame. Therefore, the main load-carrying beams of the vehicle frame of the prior art are large in size, resulting in a heavy weight of the whole vehicle frame, especially for large-displacement motorcycles, the vehicle frame seems thick and heavy. [0003] Therefore, the thick and heavy motorcycle frame not only wastes space in volume, but also uses a lot of materials, which increases the cost and...

AI Technical Summary

Problems solved by technology

Therefore, the main load-carrying beams of the vehicle frame of the prior art are large in size, which causes the weight of the whole vehicle frame to be heavy, especially for large-displacement motorcycles, the vehicle frame seems thick and heavy

[0003] Therefore, the thick and heavy motorcycle frame not only wastes space in volume, but also uses a lot of materials, which increases the cost and increases the weight of the whole vehicle, which is not conducive to the energy saving and emission reduction of motorcycles, and is more flexible.
