Problems solved by technology

There are basically three types of models made with them: prince bikes, straddle bikes, and off-road vehicles; the drag distance of the front wheels of these three models is fixed, which is also the common point of all motorcycles now, because the steering The standpipe of the shaft head is fixedly welded on the frame, which causes the rider’s riding posture to never change, and will feel tired after riding for a period of time. Aiming at the problems existing in the above-mentioned prior art, a research design A vehicle frame that can alleviate driving fatigue and can freely change the shape is necessary to overcome the problems existing in the prior art

Embodiment Construction

[0029] The specific embodiment of the present invention is shown in accompanying drawing, is made of left frame 6, right frame 7, linkage mechanism (1,2,3,4,8,9,39), connecting shaft (1,5,10,11) , 13), composed of connecting blocks 12; it is characterized in that the left frame 6 and the right frame 7 are mirror-symmetrical independent structures, which are respectively composed of high-quality frame tubes and connecting plates with plug-in welding, and on each frame There are five connection points corresponding to each other; the cross connection shaft 1, the connection block 12, the main connection shaft 11, the rear connection shaft 5 and the lower connection shaft 10, on the respective corresponding connection points, connect the left frame 6 and the right frame 7 are connected into a complete and firm space frame structure.

[0030] The two ends of the horizontal axis of the cross connection shaft 1 are connected with the bearing 14 at the connection points 6.1 and 7.1, ...

Abstract

Disclosed is a transformable motorcycle frame which is formed by combining a left frame, a linkage mechanism, a right frame, connecting shafts and a connecting square block. The left frame and the right frame are of an independent structure in mirror symmetry and are connected to form a firm spatial frame structure under simultaneous connecting action of a crossed connecting shaft, the connecting square block, a main connecting block, a rear connecting shaft and a lower connecting shaft; the linkage mechanism is mounted between the left frame and the right frame by utilizing the crossed connecting frame, a bottom fork connecting shaft and the main connecting shaft and composed of the crossed connecting shaft, a bidirectional hydraulic cylinder, a hydraulic power unit, a pull rod, a rocker arm, a single damper and a bottom fork; under acting force of extension and contraction of the hydraulic cylinder, an included angle between central axis of a vertical pipe of the crossed connecting shaft and the horizon and an included angle between a plane on which the bottom fork is positioned and the horizon are increased or decreased at the same time, and barycenter of a motorcycle body is lifted or lowered accordingly, so that front-wheel dragging distance of a motorcycle is changed, shape of the motorcycle is changed as well, driving posture is changed, and driving fatigue is relieved.

Description

technical field [0001] The invention relates to a motorcycle frame, in particular to a freely deformable motorcycle frame. Background technique [0002] The forms of the motorcycle frames used by the public 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. There are basically three types of models made with them: prince bikes, straddle bikes, and off-road veh...
