Abstract
The invention relates to a motorcycle frame, which comprises a main beam pipe, a rear inclined supporting pipe and a longitudinal beam pipe, wherein the main beam pipe is an arc flat pipe formed by welding and encircling a left sheet metal part and a right sheet metal part, and the middle part of the main beam pipe is arched backwards. The lower end of the main beam pipe is provided with a bottom fork installation shaft and a pedal support shaft, and the back surfaces of two sheet metal parts forming the main beam pipe are connected together in a sealing way between the bottom fork installation shaft and the pedal support shaft. And a side reinforcing plate is arranged between the bottom fork mounting shaft and the pedal support shaft at the outer side of the two sheet metal parts. The invention connects the original two plate metal parts with the separated area on the back surface in a sealing way, and the side surface reinforcing plate is arranged on the outer side of the two plate metal parts. Through the improvement, the strength of the lower end of the main beam pipe is enhanced, particularly the strength of the installation positions of the bottom fork installation shaft and the pedal support shaft is enhanced and balanced, the problem of pedal vibration of the motorcycle in the running process is improved to a great extent, and the riding comfort and commodity are improved.
Description
Technical field
The present invention relates to motor bike, specifically refer to a kind of frame of motorcycle that can effectively reduce the pedal vibration.
Background technology
Vehicle frame is the skeleton of motor bike, and all basically parts all are that install on the basis with the vehicle frame.The dividing mode of vehicle frame in the industry cycle has multiple, mainly is divided into knight's vehicle carriage, scooter vehicle frame and beam bending bicycle vehicle frame from big aspect.Fig. 1 is unusual a kind of structure of representative type in knight's vehicle carriage; It mainly comprises girder pipe 1, back down tube 2 and stringer pipe 3; Girder pipe 1 front end is welded with standpipe 4, and stringer pipe 3 roughly is in horizontality, and afterbody is slightly toward upwarping; Stringer pipe 3 front ends and girder pipe 1 medium position are fixed; Back down tube 2 lower ends ride over girder pipe 1 lower end position forward and welding is fixing, and back down tube 2 upper ends are fixed with stringer pipe 3 about medium positions backwards, the structure of form thus that main body three angles triangular in shape, leg-of-mutton are gone up forward respectively, rear portion and bottom being stretched out.Be provided with chain stay installation shaft 6 and pedal pivot shaft 7 in girder pipe 1 lower end.
The principal feature of the said vehicle frame of Fig. 1 is: girder pipe 1 is whole to be arc flat pipe, and the middle part is to cantle, and arc flat pipe is surrounded by the welding of left and right sides two boards gold part and formed.Chain stay installation shaft 6 and the pedal pivot shaft 7 one high and one low two boards gold parts that are horizontally through are installed in pedal on chain stay installation shaft and the pedal installation shaft again.
In above-mentioned frame of motorcycle, the back side of girder pipe 1 lower end (towards that face of tailstock portion) begins from the chain stay installation shaft, and two boards gold part 11 separates no longer weld together gradually symmetrically from the center; And the distance of separating is far away more more downwards; Separate fully in pedal pivot shaft 7 installation sites, form two parallel metal sheets 11, and the zone that separates forms a hole 10 that is similar to equicrural triangle; Just two waists here are not straight lines but camber line is seen Fig. 2 and Fig. 3.Because this panel region of separating just in time is the pedal installation region, diverse location intensity is different, and rigidity is different, because this species diversity causes motor bike pedal vibration in the process of moving bigger, traveling comfort and commodity that influence drives.In today that market competition is growing more intense, the customer requires also increasingly high to the driver comfort of motor bike, even therefore above-mentioned little error or carelessness also possibly bring influence to the sale of car load.
Summary of the invention
To the above-mentioned deficiency that prior art exists, the purpose of this invention is to provide a kind of motor bike improvement vehicle frame that can effectively reduce the pedal vibration.
Technical scheme of the present invention is achieved in that a kind of frame of motorcycle, comprises girder pipe, back down tube and stringer pipe, and the arc flat pipe that forms is surrounded in the left and right sides two boards gold part welding of serving as reasons of girder pipe, and the middle part is to cantle, and girder pipe front end is welded with standpipe.Stringer pipe front end and girder pipe medium position are fixed, and back down tube lower end and girder pipe lower end are fixed, and back down tube upper end is fixed with the stringer pipe medium position backwards.Be provided with chain stay installation shaft and pedal pivot shaft in girder pipe lower end, the back side that constitutes the two boards gold part of girder pipe links together between chain stay installation shaft and pedal pivot shaft with sealing.
The outside at two metal sheets is provided with side stiffener between chain stay installation shaft and pedal pivot shaft.
The back side at the two boards gold part that constitutes the girder pipe is provided with back side brace panel, and said back side brace panel will link together at the gold of the two boards between chain stay installation shaft and pedal pivot shaft part with sealing.
Link together to the zone sealing that the present invention separates the original two metal sheet back sides, be provided with side stiffener in the outside of two metal sheets simultaneously.Through such improvement; The intensity of girder pipe lower end is strengthened; Especially the intensity of chain stay installation shaft and pedal pivot shaft installation site is strengthened and is become balanced; The problem of motor bike pedal vibration in the process of moving improves to a great extent, and the traveling comfort and the commodity that drive are improved.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described further.
Referring to Fig. 4, on scheming, can find out frame of motorcycle of the present invention; Comprise girder pipe 1, back down tube 2 and stringer pipe 3; The arc flat pipe that forms is surrounded in girder pipe 1 left and right sides two boards gold part 11 welding of serving as reasons, and the middle part is to cantle, and girder pipe 1 front end is welded with standpipe 4 and preceding stay tube 5.Stringer pipe 3 front ends and girder pipe 1 medium position are fixed, and back down tube 2 lower ends and girder pipe 1 lower end are fixed, and back down tube 2 upper ends are fixed with stringer pipe 3 medium positions backwards.Be provided with chain stay installation shaft 6 and pedal pivot shaft 7 in girder pipe 1 lower end; The back side that constitutes the two boards gold part 11 of girder pipe between chain stay installation shaft and pedal pivot shaft, link together with sealing (and this section of prior art separates, and more to below get more open).
This osed top is connected with two kinds of implementations: one, opened local repair welding one block plate that forms opening in 11 minutes at original two boards gold part and form back side brace panel 8, will be linked together at the gold of the two boards between chain stay installation shaft and pedal pivot shaft part by back side brace panel 8 with sealing; Two, remanufacturing two metal sheets 11, two metal sheets do not have breach at the very start, with equally direct, the successive welding in other position, the back side together.
The outside at two metal sheets 11 is provided with side stiffener 9 between chain stay installation shaft and pedal pivot shaft, side stiffener 9 is welded on the metal sheet outside, sees Fig. 5 and Fig. 6.
Fig. 7 installs main pedal vibrating effect comparison diagram behind the main pedal for vehicle frame before and after improving.Curve a is for changing preceding effect among the figure, and curve b is for changing the back effect.Can find out that on scheming the motor bike vibration of pedal in the process of moving is retarded to a certain extent, particularly more obvious during high speed, the traveling comfort that drives is enhanced.
