The frame structure of the front part of the frame and its motorcycle

Abstract

The invention discloses a motorcycle frame front frame structure and a motorcycle with the motorcycle frame front frame structure. A motorcycle frame front frame structure assembly comprises a motorcycle head vertical tube, a front left main beam and a front right main beam. The front left main beam and the front right main beam are arranged in parallel. The front end of the front left main beam and the front end of the front right main beam are both connected with the motorcycle head vertical tube. The motorcycle frame front frame structure assembly further comprises a mounting plate I and a mounting plate II, wherein the mounting plate I is used for being connected with an oil tank and the mounting plate II is used for being connected with a secondary gulp valve. The transverse two ends of the mounting plate I are connected with the front left main beam and the front right main beam correspondingly, and the mounting plate II is detachably connected with the mounting plate I. The mounting plate I has the supporting and locating functions on the oil tank, and the fixation effect of the oil tank is further strengthened. Due to the fact that the mounting plate II and the mounting plate I are connected detachably, corresponding mounting structures do not need to be arranged on a beam structure of the motorcycle frame, and the uniqueness of the state of the motorcycle frame during production can be guaranteed. Meanwhile, the mounting plate II can be disassembled and assembled according to differences of configuration of motorcycle types, and the secondary gulp valve can be selected freely for installation, the management difficulty is lowered for manufacture factories, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a motorcycle component and its application, in particular to a front frame structure of a vehicle frame and a motorcycle using the structure. Background technique [0002] The motorcycle frame is an important safety component of the motorcycle, which has the functions of load bearing, anti-collision and carrying and fixing most of the accessories of the motorcycle. The existing motorcycle frame is mainly composed of the front riser, the main beam tube, the engine diagonal support tube, the large plate (equivalent to the middle tube), the tail tube and the tail tube support tube, etc., wherein the stand tube, the main beam Tubes, engine braces and large plates form the front frame of the frame, and large plates, tail pipes and tail tube stays form the middle and rear frame of the frame. In addition to installing the necessary components such as the engine and the fuel tank, the front frame may also be installed as an optional p...

AI Technical Summary

Problems solved by technology

In addition to installing the necessary components such as the engine and the fuel tank, the front frame may also be installed as an optional part of the secondary air supply valve at this position according to different vehicle configurations; in the prior art, the secondary air supply valve relies on the The air valve installation bracket is installed, and the air valve installation bracket is fixed at a certain position on the motorcycle frame. Therefore, it is necessary to set a corresponding installation structure for the positioning of the air valve installation bracket on the frame, resulting in Too much, which increases the management difficulty of the manufacturer and reduces the production efficiency
