Motorcycle frame assembly and motorcycle

Abstract

The invention discloses a motorcycle frame assembly and a motorcycle, comprising a main beam, a vertical beam and an anti-collision beam installed on the vehicle frame, an engine installation space is formed between the main beam and the vertical beam, and the anti-collision beam includes a front transverse tube and The rear cross tube, the rear cross tube is located at the corresponding position under the front of the engine and traverses the engine installation space, and the front cross tube crosses the front side of the head pipe of the frame; the invention improves the overall anti-collision structure of the frame, and the bumper adopts The combination of the front cross tube and the rear cross tube is similar to the frame structure, and the rear cross tube is arranged under the front cross tube in terms of azimuth, so that the entire left and right protection parts cover the landing range of the motorcycle after it is dumped. In addition, the overall front and rear horizontal tubes reasonably distribute the support points when dumping, which ensures the safety and comprehensiveness of protection; when in use, the front horizontal tube is located on the upper part of the front wheel and the front side of the front fork, which is convenient for installation, effective protection and good appearance , The rear cross tube is located at the bottom of the front side of the engine, corresponding to the landing point when the motorcycle is dumped, which can effectively protect the motorcycle itself and the engine, and the overall appearance is 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...

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. Passengers form an effective protection
