Description

A kind of shock-absorptive frame of bicycle
Technical field
The present invention relates to a kind of cycle frame more particularly to a kind of shock-absorptive frame of bicycle.
Background technique
Main structure of the cycle frame as bicycle, connects all parts of bicycle, sends out in whole bicycle Wave extremely important effect.The vehicle frame overwhelming majority of bicycle is all that tubular structure bracket passes through triangle frame in the prior art Structure principle is welded, and the modes such as saddle pipe damping, front fork damping that damping bicycle uses in the prior art are to some extent The problems such as that there are damping effects is poor, structure is complicated, folder is hung, so that bicycle rack is unable to fully deformation on the whole and absorption is run over Jolting in journey be easy to cause the premature fatigue of user when pavement conditions are bad, influences safety traffic and comfort level.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, a kind of damping bicycle is provided Vehicle frame.
The present invention is to be achieved by the following technical programs:
A kind of shock-absorptive frame of bicycle, including front fork sleeve, saddle casing, axis casing and rear axle crotch, feature exist In, it is equipped with vertical beam between the saddle casing and axis casing, cant beam is equipped between the axis casing and front fork sleeve, it is described Rear axle crotch includes rear axle upper boom and rear axle bottom bar, and rear axle bottom bar rear end and rod rear end on rear axle are affixed, under the vertical beam End is equipped with the engaging lug of leukorrhagia vertical beam connecting hole with rear axle crotch opposite side, and rear axle bottom bar front end and vertical beam are in lower vertical beam Connection hole is hinged, and rear axle upper boom front end is hinged with vibration damper plate, and the vertical beam is equipped with front fork sleeve opposite side and takes The engaging lug of vertical beam connecting hole, the vibration damper plate lower end and vertical beam are hinged in upper vertical beam connection hole, the vibration damper plate upper end hinge Be connected to damping spring, upper beam be equipped between the front fork sleeve and vertical beam, the upper beam is divided into two sections, including preceding upper beam and it is rear on Beam, the rear upper beam rear end and vertical beam are affixed, pass through arch attachment beam at left and right sides of the preceding upper beam rear end and rear upper beam front end Affixed, upper tail beam is equipped with the engaging lug with upper beam connecting hole, the damping spring front end and preceding upper beam and connects in upper beam before described Connect it is hinged at hole, rear axle crotch tail portion be equipped with rear axle pintle.
The vertical beam and rear upper beam junction are equipped with the connection rib that upper surface is arc upwards.
The beneficial effects of the invention are as follows:
Since rear axle bottom bar rear end and rod rear end on rear axle are affixed, rear axle bottom bar front end and vertical beam are in lower vertical beam Connection hole is hinged, and rear axle upper boom front end is hinged with vibration damper plate, and the vibration damper plate lower end and vertical beam are in upper vertical beam connecting hole Place is hinged, and the vibration damper plate upper end is hinged with damping spring, and upper beam, the upper beam point are equipped between the front fork sleeve and vertical beam It is two sections, including preceding upper beam and rear upper beam, the damping spring front end and upper beam are hinged in upper beam connection hole, logical as far as possible The deformation of bicycle rack is crossed to absorb vibration, safety and the comfort of bicycle are effectively improved, due to the preceding upper beam rear end It is affixed with arch attachment beam is passed through at left and right sides of rear upper beam front end, prevent damping spring from folder extension occurs with human contact when shrinking Phenomenon.
Since the vertical beam and rear upper beam junction are equipped with the connection rib that upper surface is arc upwards, vehicle is effectively increased The intensity of body.
Detailed description of the invention
Fig. 1 is schematic view of the front view of the invention.
Fig. 2 is detailed structure schematic diagram of the invention.
In figure:1. saddle casing, 2. vertical beams, 3. connect ribs, upper beam before 4., 5. front fork sleeves, 6. cant beams, 7. upper beams company Connect hole, 8. damping springs, vertical beam connecting hole on 9., 10. axis casings, 11. rear axle pintles, 12. rear axle upper booms, 13. arch connect Beam is connect, 14. descend vertical beam connecting holes, upper beam after 15., 16. rear axle bottom bars, 17. vibration damper plates.
Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, with reference to the accompanying drawing and most The present invention is described in further detail for good embodiment.
As shown, the present invention includes front fork sleeve 5, saddle casing 1, axis casing 10 and rear axle crotch, the saddle It is equipped with vertical beam 2 between casing 1 and axis casing 10, cant beam 6 is equipped between the axis casing 10 and front fork sleeve 5, after described Yoke frame includes rear axle upper boom 12 and rear axle bottom bar 16, and 16 rear end of rear axle bottom bar and 12 rear end of rear axle upper boom are affixed, described 2 lower end of vertical beam and rear axle crotch opposite side are equipped with the engaging lug of leukorrhagia vertical beam connecting hole 14,16 front end of rear axle bottom bar with Vertical beam 2 is hinged at lower vertical beam connecting hole 14, and 12 front end of rear axle upper boom is hinged with vibration damper plate 17, the vertical beam 2 and front fork 5 opposite side of sleeve is equipped with the engaging lug for taking vertical beam connecting hole 9, and 17 lower end of vibration damper plate is connect with vertical beam 2 in upper vertical beam Hinged at hole 9,17 upper end of vibration damper plate is hinged with damping spring 8, and upper beam, institute are equipped between the front fork sleeve 5 and vertical beam 2 It states upper beam and is divided into two sections, including preceding upper beam 4 and rear upper beam 15, rear 15 rear end of upper beam and vertical beam 2 are affixed, the preceding upper beam 4 It is affixed to pass through arch attachment beam 13 at left and right sides of rear end and rear 15 front end of upper beam, preceding 4 tail end of upper beam is equipped with band upper beam connection The engaging lug in hole 7,8 front end of damping spring and preceding upper beam 4 are hinged at upper beam connecting hole 7, and rear axle crotch tail portion is set There is rear axle pintle 11.
