Abstract
The utility model relates to a damping bicycle frame with a four bar linkage, comprising a cross beam, an oblique beam, a vertical beam, a front fork casing tube, a centre shaft casing tube, a back bottom fork, a back oblique fork, a goods shelf and a goods shelf bracket. The utility model is characterized in that a damping spring is arranged between the vertical beam and the centre shaft casing tube in the direction of the central axis of the vertical beam. Hinging pin shafts are respectively arranged between the front fork casing tube and the oblique beam, between the oblique beam and the centre shaft casing tube, between the vertical beam and the back oblique fork and between the back bottom fork and the back oblique fork to form a four bar linkage. The utility model which has the advantages of integral damping performance and long service life improves the adaptability towards roadways, lightens fatigue and improves the stability for carrying goods.
Description
The utility model belongs to the bicycle field, particularly a kind of four-bar mechanism damping bicycle vehicle frame.Be on the overall dimensions basis of original bicycle tripod, by changing its connect mechanism, and reach the vehicle frame of damping effect.
At present, the vehicle frame of standard bicycle all is the rigid body vehicle frame that utilizes triangle stable, makes it enough intensity, and is indeformable.Although some patented technology is improved on vehicle seat, alleviate cyclist's vibrations, fundamentally do not solve the vibration problems of whole locomotive body, particularly contained goods is not played the effect of alleviating vibrations, so poor effect.By it is to travel on rugged road surface, can not get stablizing loading, improves comfort, the effect that lessens fatigue.Also some technology is a mounting shock absorber on the front fork of bicycle and rear axle, makes it to become the damping modes of similar motor bike, its complex structure, and cost increases, and is difficult to promote.
The purpose of this utility model is for the cyclist provides a kind of damping, comfortable, loading pulsation-free four-bar mechanism damping bicycle vehicle frame, and it can quick and stable pass through on rugged road surface, can prolong the service life of bicycle again.
Four-bar mechanism damping bicycle vehicle frame of the present utility model, comprise the front fork sleeve pipe that is connected with crossbeam, cant beam respectively, the upright beam that is connected with crossbeam, shelf respectively, pitch the axis sleeve pipe that is connected with cant beam, the end, back respectively, pitch the fork that retreads that is connected with Li Liang, the end, back respectively, and the shelf support that is connected with shelf, it is characterized in that: on the central axial direction of upright beam, between upright beam and the axis sleeve pipe spiral damping spring is housed.The hinge joint bearing pin is housed between front fork sleeve pipe and the cant beam, and Li Liangshang is equipped with the bearing pin with the fork hinge joint of retreading, and the hinge joint bearing pin is housed, the composition four-bar mechanism respectively on back end fork and the same axis that retreads between pitching.One end of shelf support is connected with upright beam.
The utility model has the following advantages compared with the prior art:
1, has the integrated buffer performance, frame member itself, rim, spoke, axle, bearing, the suffered impulsive force of vehicle seat are eased, thereby improve overall performance, increase the service life.
But 2 at high speeds improve the comformability of road pavement by rugged and rough road surface.
3, the cyclist has comfort, lessens fatigue; Loading can increase stability.
When 4, car body moved, gravity acted on downwards vehicle frame, and pedal distance overhead is slightly to increase, rather than reduces, so can not contact to earth because of fluctuating.
5 is simple in structure, easy to maintenance, is suitable for any bicycle.
Concrete structure of the present utility model is provided by the following drawings and embodiment.
Fig. 1 is an integral structure view of the present utility model.
With existing 28 type bicycles is example: crossbeam (1) is made U type support.Upright beam (3) stays 200mm from the bottom.Axle sleeve of wearing bearing pin (13) of 180mm place, self-support beam (3) top welding.Pitch (6) and retread to weld respectively on the same axis between the fork (7) and wears the axle sleeve of bearing pin (14), (15) at the back end.The axle sleeve of bearing pin (12) is worn in welding between cant beam (2) and the axis sleeve pipe (5).The axle sleeve of bearing pin (1) is worn in welding between front fork sleeve pipe (4) and the cant beam (2).Each pin diameter is φ 8.On the central axial direction of Li Liang (3), between upright beam (3) and the axis sleeve pipe (5) with the fixing damping coil spring (10) of screw.The damping spring parameter is as follows:
Spring wire diameter: d=4.5mm
Spring external diameter: D=34mm
Spring inside diameter: D
1=25mm
Active spring coils: n=12
Lead angle: α=6.92 °
Pitch: t=11.24mm
Free height: H
o=141.6mm
Steel wire length of run: L=1306mm
Rotation direction: dextrorotation
Heat treatment hardness: HRC=45
Material: 60Si
2Mn
Fix with screw between shelf (8), shelf support (9) and the upright beam (3).
Claims (1)
1, a kind of four-bar mechanism damping bicycle vehicle frame comprises the front fork sleeve pipe (4) that is connected with crossbeam (1), cant beam (2) respectively, the upright beam (3) that is connected with crossbeam (1), shelf (8), the axis sleeve pipe (5) that is connected with cant beam (2), back end fork (6) respectively, the fork (7) that retreads that is connected with upright beam (3), back end fork (6) respectively respectively, and the shelf (9) that are connected with shelf (8), it is characterized in that:
