In order to reach foregoing invention object, the technical solution of the utility model is for a kind of double driving bicycle is provided, and it comprises vehicle frame, be fixed on the front-wheel on the front-wheel support of vehicle frame and be fixed on the pedal at vehicle frame middle part; On described front-wheel support, be provided with actuating device, connect on the bearing of two pedals and be fixed with bevel gear set, bevel gear set is connected by flexible axle with actuating device.
Preferably, described actuating device comprises driving device and the transmission system being arranged on front-wheel support and is arranged on the chain wheel set on front-wheel, in driving device and chain wheel set, is socketed with chain, and chain middle part is through transmission system; Described flexible axle is connected with driving device.
Preferably, described actuating device comprises the driving device that is arranged on front-wheel and is fixed on the fixed support on front-wheel support, and described flexible axle is connected with driving device through after fixed support.
Preferably, on described front-wheel support, bumper is also installed.
Preferably, between described chain and front-wheel support, be provided with V-arrangement spring.
Preferably, described transmission system is change-speed box.
Preferably, described driving device comprises sprocket wheel and finishing bevel gear cuter together with sprocket engagement.
Preferably, on described bevel gear set and actuating device, be provided with flexible shaft end.
Preferably, the front fork width of described vehicle frame equals back vent width.
The beneficial effects of the utility model are: step on pedal, the flexible axle that power is connected through the bevel gear set with fixing on bearing through pedal passes to the actuating device on front-wheel support, realize the driving of front-wheel, thereby solved, when bicycle moves on irregular road surface, occur the problem of skidding.
Accompanying drawing explanation
Fig. 1 is the partial schematic diagram of the double driving bicycle of a kind of embodiment;
Fig. 2 is the back view of Fig. 1;
Fig. 3 is the partial schematic diagram of the double driving bicycle of another kind of embodiment.
Wherein, 1, flexible axle; 2, pedal; 3, chain; 4, driving device; 5, V-arrangement spring; 6, chain wheel set; 7, change-speed box; 8, bevel gear set; 9, bearing; 10, vehicle frame; 11, fixed support; 12, front-wheel support.
The specific embodiment
embodiment mono-
As depicted in figs. 1 and 2, this double driving bicycle comprises vehicle frame 10, is fixed on the front-wheel on the front-wheel support 12 of vehicle frame 10 and is fixed on the pedal 2 at vehicle frame 10 middle parts; On described front-wheel support 12, be provided with actuating device, connect on the bearing 9 of two pedals 2 and be fixed with bevel gear set 8, bevel gear set 8 is connected by flexible axle 1 with actuating device.
When guaranteeing cycle racing in non-slip situation, the adjusting driving before and after realizing, described actuating device comprises driving device 4 and the transmission system 7 being arranged on front-wheel support 12 and is arranged on the chain wheel set 6 on front-wheel, in driving device 4 and chain wheel set 6, be socketed with chain 3, and chain 3 middle parts are through transmission system 7; Described flexible axle 1 is connected with driving device 4.
Wherein, driving device 4 comprises sprocket wheel and finishing bevel gear cuter together with sprocket engagement, on bevel gear set 8 and actuating device, is provided with flexible shaft end; Between described chain 3 and front-wheel support 12, be provided with V-arrangement spring 5; The front fork width of described vehicle frame 10 equals back vent width; Described transmission system 7 is change-speed box.
Bicycle, when rapid movement, for the comfort level that bondsman is sitting in, is also provided with bumper on front-wheel support 12; Time impact on chain in order to dissolve that bumper shrinks is provided with V-arrangement spring 5 between chain and front-wheel support.
The realization that the front and rear wheel of this embodiment drives: by regulating speed change speed regulation device 7, want back-wheel drive just trailing wheel speed to be tuned up a little, want f-w-d just front-wheel speed to be tuned up a little, drive just that the speed furnishing of front and back wheel is the same simultaneously.To fall down in order preventing from skidding, preferably the speed difference of front and back wheel to be turned down a bit, safer like this.
embodiment bis-
As shown in Figure 3, this double driving bicycle comprises vehicle frame 10, is fixed on the front-wheel on the front-wheel support 12 of vehicle frame 10 and is fixed on the pedal 2 at vehicle frame 10 middle parts; On described front-wheel support 12, be provided with actuating device, connect on the bearing 9 of two pedals 2 and be fixed with bevel gear set 8, bevel gear set 8 is connected by flexible axle 1 with actuating device; Described actuating device comprises the driving device 4 being arranged on front-wheel and is fixed on the fixed support 11 on front-wheel support 12, after described flexible axle 1 passes fixed support 11, is connected with driving device 4.
