Abstract
The utility model relates to a shock-proof frame for a bicycle, mainly composed of the fork frame of a front wheel, a transverse beam, a side beam and a back frame, wherein, the transverse beam is fixedly connected with the back frame together, and the fork frame of the front wheel is composed of an upper bracket and a lower bracket, which are connected together through a Z-shaped connecting piece; the transverse beam and the upper bracket are fixed together, one end of the side beam is fixedly connected with the lower bracket, and the other end is connected with a fulcrum fixed on the back frame and can rotate around the fulcrum. The utility model has the advantages of simple structure, good shock-proof effect and long service life without being damaged easily, and is mainly used in the human power vehicle, such as the bicycle, the tricycle, etc.
Description
The utility model is a kind of later-model body frame structure for automotive, relates in particular to the vehicle frame of cushioning effect.
At present, the body frame structure for automotive of rickshaws such as existing bicycle or three-wheel vehicle as shown in Figure 1, mainly be made up of crotch 20, crossbeam 21, auxilliary beam 22 and the back vehicle frame 23 of front vehicle wheel, crossbeam 21, auxilliary beam 22 and back vehicle frame 23 are integral structure, and the crotch 20 and the integral structure of front vehicle wheel are consolidated.Advantages such as though this vehicle frame has firmly, bearing capacity is strong, but because it is for being rigidly connected, when wheel is passed through when jolting the road surface,, very limited though the front truck tire has damping effect, under the effect of shock effect power N1, front-wheel has the mobile gesture that rises, so front vehicle wheel is upper and lower jolts, and vehicle frame is shaken thereupon, influence people and control travel direction and pedal traveling comfort when riding, and wheel, vehicle frame are fragile.
The purpose of this utility model is a kind of shock-absorbing vehicle frame of design, and it is simple in structure, has damping property and durability preferably, strengthens the function that turns to of front vehicle wheel.
The designed shock-absorbing vehicle frame of the utility model mainly is made up of crotch, crossbeam, auxilliary beam and the back vehicle frame of front vehicle wheel, crossbeam is consolidated with the back vehicle frame, the crotch of front vehicle wheel is made of upper bracket and lower bracket two parts, connect by " Z " type attaching parts between the upper and lower support, crossbeam and upper bracket are fixed together, one end of auxilliary beam is captiveed joint with lower bracket, and the other end is connected with fulcrum on being fixed on back vehicle frame, can rotate around fulcrum.
For the shape that keeps above-mentioned " Z " type attaching parts and when using contractility is arranged, in " Z " type attaching parts of the shock-absorbing vehicle frame that the utility model is designed, wherein connecting rod is an elastic rod, and the interior angle that can make " Z " type attaching parts is in 0 °～180 ° scopes.
In the designed shock-absorbing vehicle frame of the utility model, the middle connecting rod of " Z " type attaching parts is cylindrical torsion spring.
In the designed shock-absorbing vehicle frame of the utility model, also be provided with the shock-absorbing element, between the lower bracket of auxilliary beam or front vehicle wheel and the car body of fixing.
For easy for installation, keep the attractive in appearance of vehicle frame, in the designed shock-absorbing vehicle frame of the utility model, the two ends of shock-absorbing element are consolidated on sub-frame and the back vehicle frame.
The shock-absorbing element of the shock-absorbing vehicle frame that the utility model is designed is an elastic element, to improve shock-proof effect.
The designed shock-absorbing vehicle frame of the utility model is when using, as road bump, move on the front vehicle wheel when forming arc swing, assist beam with front vehicle wheel crotch bonded assembly because it can rotate around the fulcrum of junction, and auxiliary swinging, the direction of control " Z " type attaching parts, to reduce the amplitude of fluctuation that handlebar produces because of vibrations, keep direct of travel, the meanwhile strength of " Z " type attaching parts and shock-absorbing element absorbing vibration, play cushioning effect, the amplitude that reduces to jolt.
The advantage of the shock-absorbing vehicle frame that the utility model is designed is:
1. simple in structure, damping effect is strong.Because " Z " type attaching parts is set on the crotch of its vehicle frame, and auxilliary beam can swing, and sets up the shock-absorbing element again between auxilliary beam and fixing car body, therefore greatly reduces by the way caused car body vibrations of jolting.
2. drive comfortablely, alleviate human-body fatigue.Because vibrations alleviate, and designed auxilliary beam has the effect of correcting vehicle frame swaying direction, so handlebar control control comfort, no matter be the cyclist or feel relief per capita by bus, comfortable, long-time indefatigability.
3. vehicle frame is not fragile, long service life.Vehicle frame no longer is being rigidly connected in the past, and some parts of forming vehicle frame have certain elasticity, when reducing vibrations to the impulsive force that connecting portion produced, thereby reduce damages such as collision, fracture, have the protection vehicle frame, the effect that increases the service life.
The designed shock-absorbing vehicle frame of the utility model mainly is suitable on the small manual cars such as bicycle, three-wheel vehicle.
Fig. 1 is the constructional drawing of original vehicle frame.
Fig. 2 is the constructional drawing of the designed shock-absorbing vehicle frame of the utility model.
Fig. 3 is the running condition distortion scheme drawing of Fig. 2.
Fig. 4 is the cutaway view at crotch point of connection and " Z " type attaching parts place among Fig. 2.
In conjunction with specific embodiments the embodiment and the effect of the designed shock-absorbing vehicle frame of the utility model is described further with reference to the accompanying drawings below.
Embodiment
Shock-absorbing vehicle frame as shown in Figure 2, mainly form by crossbeam 1, crotch 2, auxilliary beam 3 and the back vehicle frame 4 of front vehicle wheel, the crotch 2 of front vehicle wheel is divided into two parts, upper bracket 5 and lower bracket 6, connect by " Z " attaching parts 7 between the upper and lower support, the middle connecting rod 8 of " Z " type attaching parts 7 is elastic cylindrical torsion spring, the vibrations when travelling to alleviate.The junction of crotch 2 and " Z " type attaching parts 7 as shown in Figure 4.One end and the upper bracket 5 of crossbeam 1 are fixed together, and the other end is fixed together with back vehicle frame 4.One end and the lower bracket 6 of auxilliary beam 3 are fixed together, and the other end is connected with back vehicle frame 4 by the last fulcrum 9 that is fixed on back vehicle frame 4, and fulcrum 9 is a rotating shaft, and auxilliary beam 3 can rotate around fulcrum 9.Between auxilliary beam 3 and back vehicle frame 4 shock-absorbing element 10 is installed, shock-absorbing element 10 is shaft-like elastic component, plays the effect of absorbing vibration power.In the process of moving, as shown in Figure 3, when Uneven road produces vibrations, the crotch 2 of front vehicle wheel is given a shock application force N2, present the trend of moving, cause " Z " type attaching parts 7 elastic deformations, auxilliary beam 3 rotates around fulcrum 9 thereupon, make on the end arc of captiveing joint and move with lower bracket 6, and meanwhile, shock-absorbing element 10 elastic stretchings, make the shock-absorbing element 10 and the coupling end of auxilliary beam 3 move to the B point by the A point, under the elastic force effect of shock-absorbing element 10, hinder auxilliary beam 3 and arbitrarily move, make auxilliary beam 3 play the correcting effect, and shaking force is weakened.The crotch 2 that can find out front vehicle wheel does not thus produce rigid impulsive force when road bump, each parts of vehicle frame are played a protective role.This vehicle frame is applied in bicycle or other rickshaw, and vehicle frame itself can produce incabloc function, certainly will improve the service life of car, no matter is by bike or takes the people of car, all can alleviate the fatigue of jolting and forming, and uses more convenient, reliable.
