Lifting motorcycle frame and motorcycle

Abstract

The invention discloses a lifting motorcycle frame which comprises a front flat fork and a rear flat fork. The upper end of the front flat fork and the upper end of the rear flat fork are hinged at one position, a first retractable adjusting device is horizontally arranged between cross rods of the front flat fork and the rear flat fork, and the upper end of the rear flat fork is connected with acushion platform extending rearwards. The first retractable adjusting device extends and retracts in the horizontal direction to adjust the ground clearance and the gravity center of a whole motorcycle at the hinging position of the front flat fork and the rear flat fork, and the distance between two wheels is changed; the lifting motorcycle frame can be suitable for different road conditions, andduring off-road driving, the first retractable adjusting device is retracted, the ground clearance and the gravity center of the whole motorcycle are increased; when the motorcycle travels on the highway road condition and a racing track, the corresponding gravity center is decreased accordingly, the all road condition passing ability of the corresponding motorcycle is achieved, and the driving performance of the motorcycle is improved.

Description

technical field [0001] The invention relates to the technical field of two-wheel vehicle frames, in particular to a lifting frame and a motorcycle. Background technique [0002] The forms of motorcycle frames commonly used at present are mainly divided into three categories: the main beam structure frame, the rhombus frame, and the bracket frame. The main beam structure frame is also called the spine frame, which is a frame with one or two main beams as the backbone; the diamond-shaped frame is diamond-shaped, also known as the diamond frame, which belongs to the space structure. Form, the engine is placed horizontally in the diamond shape, as a support point of the frame; the bracket type frame is shaped like a cradle, also known as the cradle frame, which is also a space structure form, the engine is installed in the cradle shape, and there is a steel pipe support below , to protect the engine. The models manufactured based on the above frames fall into three categories:...

AI Technical Summary

Problems solved by technology

[0003] The above models are suitable for different road conditions and terrains, but in other road conditions, there are problems of poor passing ability and poor driving experience

Specifically, the prince car is suitable for long-term riding on the road, but has poor passing ability when driving on mountain roads and other places; It has good passing ability but the overall frame is high, and its riding posture is prone to fatigue when riding on the road for a long time, and the driving experience is poor

[0004] In daily life, drivers often face different road conditions and terrains when driving, and the models corresponding to any of the above-mentioned frames will have the problem of weak passing ability and poor driving experience in non-specific road conditions.
