Description
Technical Field
The utility model belongs to the technical field of the motorcycle frame technique and specifically relates to a novel whole low pressure casting motorcycle frame of big discharge capacity.
Background
In the prior art, most of motorcycle aluminum alloy frames adopt the technology of combining forged aluminum parts (or cast aluminum parts) and aluminum profiles in the aspect of manufacturing technology. The welding type frame has the defects of large welding deformation, poor guarantee of size and more welding defects. The motorcycle is easy to break under various comprehensive stress conditions of torsion resistance and bending resistance under the working condition of a complex road. In addition, because the dimension is not guaranteed well, the appearance part of the whole vehicle is provided with a gap or interference after being assembled, the front wheel and the rear wheel are not in line, and the controllability of the whole vehicle is poor.

Detailed Description
In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and techniques are omitted so as to not unnecessarily limit the invention.
As shown in fig. 1 to 5, a novel large-displacement integral low-pressure cast motorcycle frame is integrally formed by adopting a low-pressure casting technology, and the overall deformation of the motorcycle frame is small, the strength is high and the like because the disadvantages caused by welding after split manufacturing are avoided; in addition, the defects of under-casting, shrinkage cavity, shrinkage porosity and the like are reduced. The frame is made of aluminum alloy, so that the frame is high in strength, light in weight and simple and elegant in appearance.
The frame body comprises a front vertical pipe 1, a left beam 2, a right beam 3, a main beam 4 and a middle beam 5. The left beam 2 and the right beam 3 are respectively arranged at two sides of the frame body, and the front ends of the left beam 2 and the right beam 3 are gathered inwards and then are connected with the front vertical pipe 1; the rear ends of the left beam 2 and the right beam 3 are bent downwards to form a frame rear connecting structure 6, so that the frame rear connecting structure is convenient to be matched and connected with various rear bottom forks. The middle beam 5 is transversely arranged and connects the middle parts of the left beam 2 and the right beam 3; the left and right sides of the centre sill 5 are provided with central shock-absorbing mounting structures 7. The main beam 4 is obliquely arranged up and down and is positioned between the left beam 2 and the right beam 3; the upper end of the main beam 4 is connected with the joint of the front ends of the left beam 2 and the right beam 3; the frame body integrally adopts a embrace type structure, and the main beam 4 is connected with an engine. The inner sides of the left beam 2 and the right beam 3 are respectively provided with a hollow structure 8, and a plurality of reinforcing ribs 9 are arranged at the hollow structures 8, so that the overall weight of the frame is reduced, and meanwhile, the toughness of the frame is improved.
In addition to the technical features described in the specification, the technology is known to those skilled in the art.
Although the specific embodiments of the present invention have been described with reference to the drawings, the present invention is not limited thereto, and various modifications or variations that can be made by those skilled in the art without inventive labor are still within the scope of the present invention.
