Abstract
The utility model discloses a motorcycle frame front body assembly which comprises a motorcycle head pipe. A front main pipe and a front oblique pipe are arranged at the same side of the motorcycle head pipe. A front support pipe is arranged between the front main pipe and the front oblique pipe. The motorcycle head pipe, the front main pipe, the front oblique pipe and the front support pipe are straight pipes. A left main pipe and a right main pipe are arranged on the lower portion of the front main pipe. A left lower main pipe and a right lower main pipe are arranged on the lower portion of the front oblique pipe. The included angle between the front main pipe and the horizontal line is 24 degrees. The included angle between the front oblique pipe and a plumb line is 17 degrees. The included angle between the support pipe and the horizontal line is 12 degrees. Through optimized design of angles of surrounding pipe fittings of an oil-cooling machine oil pool, the welding difficulty of the machine oil pool is greatly reduced, production hours of a motorcycle frame is reduced, service life of the motorcycle frame is prolonged, and oil leakage probability of a motorcycle frame oil cooling system is reduced.
Description
Technical field
The utility model relates to a kind of motorcycle frame structure, particularly relates to a kind of assembly of frame of motorcycle precursor.
Background technology
Frame of motorcycle precursor welding assembly comprises head tube, and on head tube, homonymy is welded with former pipe of the frame and front inclined tube, is welded with vehicle frame front support pipe between former pipe of the frame and front inclined tube.Front supervisor's bottom is provided with the left and right supervisor, and the bottom of front inclined tube is welded with the lower supervisor in left and right.The zone that consists of between head tube, front supervisor, front inclined tube and front support pipe is for welding oil cooling machine oil pond, and the zone that consists of between supervisor under front support pipe, front supervisor, front inclined tube, left and right supervisor and left and right is for driving engine is installed.Be connected by pipeline between machine oil pond and driving engine, to provide cooling machine oil to driving engine.But in prior art, due to the angle limits between vehicle frame precursor welding assembly each several part pipe fitting, cause machine oil pond welding difficulty, poor welding quality, thus cause production efficiency low, and vehicle frame service life is low, oil cooling system oil spill rate is high.
Therefore those skilled in the art are devoted to develop a kind of welding oil cooling machine oil pond simple frame of motorcycle precursor assembly that makes.
The utility model content
Because the defects of prior art, technical problem to be solved in the utility model is to provide a kind of making and welds oil cooling machine oil pond simple frame of motorcycle precursor assembly.
For achieving the above object, the utility model provides a kind of frame of motorcycle precursor assembly, comprises head tube; The homonymy of described head tube is provided with front supervisor and front inclined tube; Be provided with the front support pipe between described front supervisor and front inclined tube; Described head tube, front supervisor, front inclined tube and front support pipe are straight tube; Described front supervisor's bottom is provided with left supervisor and right supervisor; The bottom of described front inclined tube is provided with lower-left supervisor and bottom right supervisor; Described front supervisor and horizontal angle are 24 °; The angle of described front inclined tube and plumb bob vertical is 17 °; Described support tube and horizontal angle are 12 °.
Better, described front supervisor and front inclined tube and the welding of described head tube; Described front support pipe and described front supervisor and the welding of front inclined tube; Described front supervisor's lower end is provided with mounting bracket assembly on rear shock absorber; Mounting bracket assembly welding on described left and right supervisor and described rear shock absorber; Described front inclined tube and described lower left and right supervisor's welding.
The beneficial effects of the utility model are: the utility model is by the optimal design to pipe fitting angle around the oil cooling machine oil sump, make head tube and front inclined tube, front supervisor cross the weld seam of weld distribute more reasonable, can not produce " built-up welding " phenomenon, and the welding difficulty in machine oil pond is reduced greatly, thereby reduced the production hour of vehicle frame, increase the service life of vehicle frame, and reduced the leakage of oil probability of vehicle frame oil cooling system.
Description of drawings
Fig. 1 is the structural representation of the utility model one specific embodiment.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Fig. 3 is working state schematic representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As depicted in figs. 1 and 2, a kind of frame of motorcycle precursor assembly comprises head tube 1, and the homonymy of head tube 1 is welded with front supervisor 2 and front inclined tube 3, is welded with front support pipe 4 between front supervisor 2 and front inclined tube 3.Head tube 1, front supervisor 2, front inclined tube 3 and front support pipe 4 are straight tube.
Front supervisor's 2 bottom is provided with mounting bracket assembly 10 on rear shock absorber, is welded with left supervisor 5a and right supervisor 5b on rear shock absorber on mounting bracket assembly 10, and the bottom of front inclined tube 3 is welded with lower-left supervisor 6a and bottom right supervisor 6b.
Front supervisor 2 is 24 ° with horizontal angle theta 1, and front inclined tube 3 is 17 ° with the angle theta 2 of plumb bob vertical, and front inclined tube 3 is 12 ° with horizontal angle theta 3.
As shown in Figure 3, the zone that consists of between head tube 1, front supervisor 2, front inclined tube 3 and front support pipe 4 is used for welding oil cooling machine oil pond 7, the zone that consists of between supervisor under front support pipe 4, front supervisor 2, front inclined tube 3, left and right supervisor and left and right is used for installing driving engine 8, is connected by pipeline 9 between machine oil pond 7 and driving engine 8.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all technical personnels are in the art complied with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection domain by claims.
