Description
Technical field
The invention belongs to technical field of motorcycles, specifically, relate to a kind of frame assembly of riding-type motorcycle.
Background technology
The vibration of motor bike not only influences its road-holding property and safety, the more important thing is the travelling comfort that having a strong impact on the people and healthy.Therefore, the travelling comfort of motor bike is exactly the ability that motor bike makes the certain comfort level that is had in chaufeur and the residing vibration environment of occupant in the process of moving.Wherein, skeleton is the matrix of whole motor bike, and motor cycle engine and speed change drive assembly, steering hardware, suspension gear, wheel etc. all are coupled to an integral body by frame assembly.Skeleton not only will carry the weight of motorcycle part, occupant and goods, also will bear the effect from external excitations such as mechanical operation such as ground-surface impact, driving engines when the road driving of injustice.
The frame assembly of existing riding type car belongs to traditional steel design, is welded by round steel pipe and steel plate.The car load max. speed is 90Km/h, is subjected to the impact of engine running vibration, and front pedal vibrates bigger when speed per hour 60～90Km/h, and the rear leg rest of shelf begins vibration from speed per hour 30Km/h and just becomes big, and these have all greatly reduced the comfortableness of driving.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of frame assembly of riding type motorcycle that can effectively reduce the engine vibration influence.
Technical scheme of the present invention is as follows: a kind of frame assembly of riding type motorcycle, the bottom of head tube and the welding of the upper end of front inclined tube, the top of head tube and the front person in charge's front end are fixed, the front person in charge's rear end is welded on left, on the tube connector between the right person in charge front portion, left, the right person in charge's front end respectively with front left, the top welding of right support pipe, left, the right person in charge's rear end respectively with rear left, the right person in charge's middle part welding, described front left, the upper end of right support pipe is fixed on the two sides at front person in charge rear portion, front left, the bottom of right support pipe respectively with rear left, the right person in charge's front end welding, described front left, be provided with between the bottom of right support pipe, lower transverse tubule, wherein be welded with side by side two first journal stirrups on the upper lateral tube, be welded with side by side two second journal stirrups on the lower transverse tubule, in described front left, the rear of right support pipe bottom is equipped with rear leg rest mounting pipe, be somebody's turn to do the front end of rear leg rest mounting pipe and corresponding front support pipe welding, the rear end of rear leg rest mounting pipe is connected to manage with the corresponding rear person in charge by rear leg rest and connects, and its key is: connect into an integral body by support between described two first journal stirrups and two second journal stirrups.
Because skeleton rigidity has a great impact the intrinsic frequency of frame assembly, improve the vibration resistance of frame assembly, reduce the response of to external world excitation and will set about from the rigidity that improves skeleton.The present invention will install between first journal stirrup of driving engine and second journal stirrup and be fused by support, and the antivibration effect is remarkable, can effectively reduce the influence of engine operation to skeleton, has improved the ride comfort of motor bike greatly.
Above-mentioned support is uncovered box like structure forward, and the side plate of this support the right and left is hook, and the upper end of side plate and first journal stirrup be affixed and merge welding, fits with second journal stirrup and also weld in the lower end of side plate.Support adopts box like structure, and intensity is reliable, is difficult for deforming, and has further reduced the influence of engine vibration to skeleton; The moulding of rack side plate and the bottom of preceding support tube adapt, and when guaranteeing compact conformation, have avoided engine installation is caused adverse effect.
In order to increase the be connected bonding strength of pipe of rear leg rest mounting pipe and rear leg rest, reduce the vibration at rear leg rest place, be connected pipe, the rear person in charge and the formed angle of front support pipe of the rear leg rest mounting pipe of above-mentioned the same side, rear leg rest is welded with second stiffener, and the angle that rear leg rest mounting pipe and rear leg rest are connected between the pipe is welded with the 3rd stiffener.
Beneficial effect: the present invention can increase the structural strength of engine installation site so that front pedal when speed per hour 60～90Km/h, the rear leg rest of shelf from speed per hour 30Km/h begin vibration be improved significantly, Effective Raise the comfortableness of driving.
