Description
The utility model relates to a kind of bicycle that spark ignition engine is housed, and particularly has the gasoline morpet of shock absorbing apparatus.
Existing Regular Bicycle because its speed is limited, does not generally need to adorn shock absorbing apparatus.According to Patent Office of the People's Republic of China's utility model patent communique, designed at present have front shock-proof device respectively, back shock-absorbing, three kinds of anti-vibration bicycles of seat cushion shock-absorbing.A kind of lever-type front shock-proof device device is arranged, be contained on the bicycle front fork.Structure is complicated, increases car weight and cost.Also have a kind of sense of jolting that is contained in vertical anti-vibration device under the bicycle saddle cushion, can alleviates the rider, but when the bicycle front-wheel was hit, it can not play the shock-absorbing effect, this moment, the rider easily took off handle, caused danger.A kind of rear shock absorber on the chain stay behind the bicycle that is contained in is still arranged.The problem that it exists is.The vertical support of original schoolbag frame contradicts with the effect of rear shock absorber, perhaps cancels schoolbag frame, and perhaps long tube of weldering supports schoolbag frame on vehicle frame, not only wastes steel, and face and outward appearance are ugly.At present, existing several gasoline morpets come out, and minority is equipped with the rear shock absorber of motor bike, but can't solve the schoolbag frame problem.And the forward and backward Shock absorber of motor bike is big and heavy, complex structure, and the cost height is not suitable for being applied on the regular-grade gasoline morpet.
The purpose of this utility model is at the deficiencies in the prior art part, to design a kind of simple, effective, safe gasoline power-assisted anti-vibration bicycle.The further purpose of the utility model is to design a kind of schoolbag frame that does not influence the new-type supporting construction of rear shock absorber effect.
The utility model is by vehicle frame, front and rear wheel, front fork, tap, back chain stay, spark ignition engine, the foot-operated composition.It is characterized in that between front fork and tap, installing the front shock-proof device device, between back chain stay and vehicle frame, rear shock absorber is installed, the front shock-proof device device is by preceding fork shaft, packing ring, stage clip, nut, overcoat, on, lower chuck and steel bowl, locating dowel pin is formed, preceding fork shaft is welded on the front fork, stage clip passes through packing ring, nut is pressed on the preceding fork shaft, overcoat passes through nut, on, lower chuck is fixed on the vehicle frame, one circular pin hole is respectively arranged on overcoat and the upper grip, there is an axial cotter way at preceding fork shaft corresponding circle shaped pin hole place, locating dowel pin inserts this axial cotter way by circular pin hole, rear shock absorber is by interior cover, overcoat, main shaft, stage clip, nut, journal stirrup is formed, interior cover one end is captiveed joint with the back chain stay, and the other end has annular end face, overlaps in main shaft one end inserts, the middle part has a step to be stuck in the inner sleeve shape end face, other end captive joint journal stirrup, journal stirrup are fixed on cover pipe below on the vehicle frame, outside overlapping in overcoat one end is enclosed within, the other end has annular end face, and compression spring sleeve is on main shaft.Withstand between the inside and outside collar-shaped end face, nut sleeve is outside on the main shaft of collar-shaped end face one side.
Have under the situation of rear shock absorber.The further feature of the utility model is.Schoolbag frame is made up of inside casing, inside casing connecting rod, housing, housing connecting rod.Inside casing connecting rod captive joint cover pipe, housing connecting rod captive joint journal stirrup.
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.
Fig. 1 is the utility model integral structure scheme drawing.
Fig. 2 is the utility model front shock-proof device device structural representation.
Fig. 3 is the utility model rear shock absorber structural representation.
As shown in Figure 1, the utility model is made up of vehicle frame 3, front-wheel 1, trailing wheel 11, front fork fork 12, tap 4, back chain stay 25, spark ignition engine 10, fuel tank 9, foot-operated 13.Front shock-proof device device 2 is installed between front fork and tap, below cover pipe 5 on the vehicle frame, is located to fixedly mount a journal stirrup 8 for about 80~100 millimeters, between journal stirrup and back chain stay, rear shock absorber 7 is installed.Schoolbag frame is by inside casing 32, inside casing connecting rod 6, housing 33.Housing connecting rod 34 is formed, and internal and external frames is parallel to the ground, inside casing connecting rod 6 captive joint cover pipes 5, housing connecting rod 34 captive joint journal stirrups 8.Schoolbag frame of the present utility model is changed into the lever gusseted with the back support of routine, under the prerequisite that does not influence the rear shock absorber effect, schoolbag frame is able to conveniently, install attractive in appearancely, save steel, alleviate car load from weight, schoolbag frame can carry 80 kilograms load and indeformable.
As shown in Figure 2, the front shock-proof device device is by preceding fork shaft 14, packing ring 15, stage clip 16, nut 17, overcoat 23, upper and lower chuck 20,18 and go up lower steel bowl 24,19, locating dowel pin 22 is formed, preceding fork shaft is welded on the front fork 12, stage clip one end is pressed on the packing ring 15, one end is held out against by nut 17, before being enclosed within, overcoat 23 on the fork shaft, is fixed on the vehicle frame 3 by nut, upper and lower chuck.Because the effect of upper and lower steel bowl, handlebar 4 can respectively have a circular pin hole 21 on left rotation and right rotation, overcoat and upper grip on the vehicle frame, before the corresponding overcoat of fork shaft and upper grip circular pin hole place one axial cotter way 35 is arranged, locating dowel pin 22 is inserted these axial cotter ways 35, is given stage clip 16 with about 20 kilograms precompressed compression, simultaneously preceding fork shaft can only be moved axially along overcoat by circular pin hole 21.When the utility model bicycle during at scraggly ground run, ground acts on the front fork in the face of the recoil of front-wheel.Stage clip before this moment on the fork shaft makes this recoil obtain buffering and passes to nut, and preceding fork shaft is axially done some along overcoat to move up and down under the restriction of locating dowel pin, thereby makes tap obtain shock-absorbing, the rider can not take off, guarantee traffic safety.
As shown in Figure 3, rear shock absorber is made up of interior cover 27, overcoat 29, main shaft 28, stage clip 30, nut 31, journal stirrup 8.Interior cover one end is captiveed joint with back chain stay 25 by rivet 26, the other end has annular end face 37, cover in main shaft one end inserts, the middle part has a step 36 to be stuck in the inner sleeve shape end face, the other end and journal stirrup 8 riveted joints, journal stirrup is fixed on cover pipe below (referring to Fig. 1 seat cushion sleeve pipe 5, journal stirrup 8) on the vehicle frame, outside overlapping in overcoat one end is enclosed within, the other end has annular end face 38, compression spring sleeve is on main shaft, withstand between the inside and outside collar-shaped end face 37,38, nut 31 is enclosed within on the main shaft of overcoat annular end face 38 1 sides, gives overcoat with 20 kilograms precompressed compression by nut.When meeting scraggly road surface, act on the chain stay of back in the face of the recoil of trailing wheel.This moment, inner sleeve shape end face promoted stage clip, and main shaft is longitudinal travel in interior cover, played the shock-absorbing effect, made the rider not have the sense of jolting on cushion thereby make this recoil obtain buffering.
The utility model is simple in structure, in light weight, and in the situation more fast again than ordinary bicycle speed, it is steadily comfortable, safe and reliable to ride seat.
