Motorcycle frame assembly and motorcycle

Abstract

The invention discloses a motorcycle frame assembly and a motorcycle. The motorcycle frame assembly comprises a main beam, a vertical beam and an anti-collision beam installed on a frame, wherein an engine installation space is formed between the main beam and the vertical beam, the anti-collision beam comprises a front transverse pipe and a rear transverse pipe, the rear transverse pipe is located at the corresponding position below the front portion of an engine and transversely penetrates through the engine installation space, and the front transverse pipe transversely crosses the front side of a frame head pipe. According to the invention, the overall anti-collision structure of the frame is improved, the bumper is of an approximate frame structure formed by combining the front transverse pipe and the rear transverse pipe, the rear transverse pipe is arranged below the rear portion of the front transverse pipe in the aspect of orientation, so that the arrangement positions of the whole left protection part and the right protection part cover the landing range of the motorcycle after the motorcycle topples over, the whole front transverse pipe and the whole rear transverse pipereasonably distribute supporting points during toppling over, and the safety and protection comprehensiveness are guaranteed; and during use, the front transverse pipe is located on the upper portionof a front wheel and the front side of a front fork, the installation is convenient, effective protection is formed, the appearance is guaranteed, the rear transverse pipe is located at the lower position of the front side of the engine and corresponds to a landing point when the motorcycle topples over, the motorcycle and the engine can be effectively protected, and the whole motorcycle is attractive and light in weight.

Description

technical field [0001] The invention relates to the safety protection of motor vehicle parts, in particular to a motorcycle frame assembly and a motorcycle with increased driving safety. Background technique [0002] Because the motorcycle is for riding, the safety factor is relatively low. Installing a firm bumper on the frame of the motorcycle is an important measure to ensure safe driving. When the motorcycle is dumped or collided, the motorcycle bumper mainly plays the role of buffer and protection. That is to say, when the motorcycle falls, it is the bumper that first contacts the road surface, and then the bumper deforms under the action of force to consume the kinetic energy of the motorcycle, which acts as a buffer to protect the motorcycle and reduces damage to the body. At the same time, due to the lateral support of the bumper, the bumper and the exhaust pipe first touch the ground when the motorcycle falls to the ground, creating a safe space for the driver, esp...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the structure of the bumper is various. The bumper of the straddle motorcycle is all located in front of the legs as a whole. The connection method of bushing welding; the extension strength of simple lugs is poor, and it is easy to deform after a long time; the flat connection of pipes is not easy to control the flatness and consistency of the cross section, and the strength cannot meet the requirements; and the connection between bushing and bumper welding way to increase the weight and affect the appearance; the main thing is that the existing bumper fails to analyze the situation when the motorcycle is dumped from the structure, but pays attention to the convenience of installation and the appearance, which leads to the inability to effectively protect the motorcycle body and driving.
