Description
Technical field
The utility model belongs to the vehicle technology field, particularly relates to a kind of shock-damping structure of Electrical Bicycle front fork.
Background technology
Existing battery-driven car front fork comprises standpipe of front fork, portal frame, fork shoulder, handle pipe and fork leg, also is respectively arranged with shock absorption device on described two handle pipes and the fork leg.This structure is had relatively high expectations to the sliding sleeve (guide part) between handle pipe and the fork leg, and long-time friction back is yielding, causes the damping effect difference even finally can not play the shock-absorbing effect, and is unfavorable for maintenance.In addition, the used parts of existing front fork are more relatively, and productive costs is also higher relatively.Relatively difficulty is regulated and change also to the front fork bumper of this structure.
Summary of the invention
The utility model purpose is to provide a kind of simple in structure at the defective of prior art, and parts are less and can conveniently regulate the Electrical Bicycle front fork structure of replacing.
The utility model adopts following technical scheme for achieving the above object:
A kind of Electrical Bicycle front fork structure, comprise standpipe of front fork and front fork fork leg, it is characterized in that: described standpipe of front fork and front fork fork leg are hinged by attaching parts with form setting and between that front and back separate, also are provided with bumper between standpipe of front fork and front fork fork leg.This structure is utilized the activity characteristic of articulated structure, front fork is pitched the road shock that leg is subjected to be delivered between front fork fork leg and the standpipe of front fork, bumper reaches shock-proof effect by compression shock absorption, and this structure can regulate and change bumper easily simultaneously.
Further: be respectively arranged with U-shaped support on described standpipe of front fork and the front fork fork leg, described attaching parts two ends respectively with standpipe of front fork and front fork fork leg on the U-shaped support that arranges hinged.This is simple and practical, the convenient making.
Further: about described front fork fork leg is divided into two, about two the fork legs top and middle and upper parts be provided with U-shaped support, on described standpipe of front fork top and the lower end be provided with U-shaped support, be provided with transverse connecting pipe between two fork legs about described, described bumper one end is hinged on the described transverse connecting pipe, and the other end is hinged on the U-shaped support of standpipe of front fork top setting.Transverse connecting pipe is set between the front fork fork leg has increased the intensity of fork leg, makes front fork not yielding, and the connection mode of this shock bracket makes only needs a shock bracket just can play the effect of damping, has saved damping part, adjust and replacing also more convenient.
Further: described attaching parts is four, two attaching partss, one end is distributed in the U-shaped support of riser upper portions both sides and in addition spacing by bolt, the U-shaped support that the other end and left and right sides front fork fork leg top arrange is hinged, two attaching partss, one end both sides or the centre of the U-shaped support that is arranged on the standpipe of front fork lower end that distribute in addition, the other end of two attaching partss with about the U-shaped support that arranges of fork leg middle and upper part hinged.Adopt this chaining part simple in structure, cost is relatively low.
Further, described bumper and about on the transverse connecting pipe of fork between the leg hard-wired U-shaped support hinged, also be provided with a transverse connecting pipe in described transverse connecting pipe lower end and connect left and right sides front fork fork leg.This is simple in structure, and is easy to make, be easy to realize, and cost is low.
The utility model adopts four-bar linkage structure, and shock-proof front-fork assembly is the external shock-proof front-fork assembly of damping, and bumper can be changed, and also can adjust hardness and the stroke of bumper simultaneously according to road conditions, adjusts traveling comfort.Can adjust hardness and the stroke of bumper according to road conditions, adjust traveling comfort.The utility model is also saved dedicated fixed screw rod, two special purpose springs, two special uses and is colluded pawl, a special-purpose member such as gantry support.Be the civilian parts of oversimplifying by professional part replacement.

Fig. 1 is the utility model scheme drawing.
Fig. 2 is the utility model birds-eye view.
Fig. 3 is the upper bracket partial schematic diagram.
Fig. 4 is the lower bracket partial schematic diagram.
The specific embodiment
As Fig. 1, a kind of Electrical Bicycle front fork structure shown in 2, comprise standpipe of front fork 1 and front fork fork leg 2, the form setting that described standpipe of front fork 1 and front fork fork leg 2 separates with front and back and hinged by attaching parts and the U-shaped support that is arranged on standpipe of front fork and pitch on the leg between standpipe of front fork and front fork fork leg, owing to be provided with U-shaped support in the standpipe of front fork upper end, be provided with journal stirrup in the vertical tube lower end, about front fork fork leg is divided into two, U-shaped support is separately fixed at top and the middle and upper part of fork leg, attaching parts always has four, the U-shaped support that two attaching partss arrange with standpipe of front fork top respectively and front fork fork leg top arrange is connected between U-shaped, in addition two attaching partss respectively with standpipe of front fork lower end U-shaped between and the front fork U-shaped support of pitching the setting of leg middle and upper part be connected; Attaching parts and standpipe of front fork and fork leg constitute quadrangle then, also are provided with bumper 4 between standpipe of front fork 1 and the front fork fork leg 2.One end of bumper is with hinged with the U-shaped support that is arranged on riser upper end, the other end with about the U-shaped support pitched on the transverse connecting pipe that arranges between the leg hinged.This structure is utilized tetragonal changeability, front fork is pitched the road shock that leg is subjected to be transformed into tetragonal deformation, and bumper between standpipe of front fork and the front fork fork leg is transferred in this deformation, reaches shock-proof effect by compression shock absorption.
Certainly, attaching parts also can be that two back-to-back fixing backs of the U-shaped support that varies in size are hinged with the U-shaped support on standpipe of front fork and the front fork fork leg, and this structure can be connected the effect that reaches same with aforesaid four attaching partss.
Also be provided with transverse connecting pipe 5 between two front fork fork legs 2 about described, described bumper 4 one ends are connected on the described transverse connecting pipe 5, and the other end is connected on the U-shaped support of standpipe of front fork 1 upper end setting.The described attaching parts that is hinged on the U-shaped support that arranges on the standpipe of front fork is distributed in U-shaped support 8 both sides, and the intensity that transverse connecting pipe has increased the fork leg is set between the front fork fork leg, makes front fork not yielding.The connection mode of shock bracket makes only needs a shock bracket just can play the effect of damping, has saved damping part, and adjustment and replacing are also more convenient.Described shock bracket is the spring shock absorption support.Adopt the spring shock absorption supporting structure simple, cost is relatively low.
Be welded with U-shaped support 6 as standpipe of front fork 1 as described in Fig. 2,3,4 and front fork fork leg 2 and two support 3 junctions up and down, described U-shaped support 6 and last lower bracket 3 are by fastening to the lock screw rod.Adopt U-shaped support mode to connect, connect reliable firm.
