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 through frame assembly.Skeleton not only will carry the weight of motorcycle part, occupant and goods, when the road driving of injustice, also will bear the effect from external excitations such as mechanical operation such as ground-surface impact, driving engines.
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 maximum speed is 90Km/h, receives the influence of engine running vibration, and preceding pedal vibrates bigger when speed per hour 60～90Km/h, and the back leg rest of shelf begins vibration from speed per hour 30Km/h and just becomes big, and these have all greatly reduced the traveling comfort 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 following: a kind of frame assembly of riding type motorcycle; The bottom of head tube and the welding of the upper end of preceding inclined tube; The top of head tube and the preceding person in charge's front end are fixed, on the connection pipe during the preceding person in charge's rear end is welded between the left and right person in charge front portion, in the left and right person in charge front end respectively with the welding of the top of preceding left and right support tube; In the left and right person in charge the rear end respectively with the left and right person in charge's in back middle part welding; Be responsible on the two sides at rear portion before the upper end of left and right support tube is fixed on before said, the bottom of preceding left and right support tube respectively with the left and right person in charge's in back front end welding, be provided with upper and lower transverse tube between the bottom of left and right support tube before said; Wherein be welded with two first journal stirrups on the upper lateral tube side by side; Be welded with two second journal stirrups on the lower transverse tubule side by side, the rear of left and right support tube bottom is equipped with back leg rest mounting pipe before said, the front end of this back leg rest mounting pipe and cooresponding preceding support tube welding; The rear end of back leg rest mounting pipe is connected to manage with the cooresponding back person in charge through the back leg rest and is connected, and its key is: connect into an integral body through support between said two first journal stirrups and two second journal stirrups.
Because skeleton rigidity has very big influence to the natural frequency of frame assembly, improve the antivibration ability of frame assembly, reduce the response of excitation to external world and will set about from the rigidity that improves skeleton.The present invention will install between first journal stirrup and second journal stirrup of driving engine and 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 a hook, and the upper end of side plate and first journal stirrup fit and weld, the also welding of fitting of the lower end of side plate and second journal stirrup.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 Joint strenght that back leg rest mounting pipe and back leg rest are connected and manage; Reduce the vibration at leg rest place, back; The back leg rest mounting pipe of above-mentioned the same side, back leg rest be connected pipe, the back is responsible for and the formed angle of preceding support tube is welded with second brace panel, back leg rest mounting pipe and after the angle that is connected between managing of leg rest be welded with the 3rd brace panel.
Beneficial effect: the present invention can increase the structural strength of engine installation position, before making pedal when speed per hour 60～90Km/h, the back leg rest of shelf from speed per hour 30Km/h begin vibration be improved significantly, effectively improved the traveling comfort of driving.
