Description
Technical field
The utility model is about a kind of bicycle driving device.
Background technology
Known in the past bicycle and man structure, as shown in Figure 1, except that main body frame 10 and be located at the tire 11 of vehicle frame 10 front and back ends and member such as trailing wheel 12, can divide into the direction control group 20 of control direction of traffic and the power drive group 25 2 big classes that tire on the drive wheels rolls in addition.
This direction control group 20 comprises handle-bar 21, these handle 21 lower ends are provided with a steering shaft 22 and are socketed on the fixed cover 101 of vehicle frame 10 front ends, these steering shaft 22 lower ends are extended with the ㄇ shape seat 23 that articulates for tire 11, make the rider see through this handle-bar control direction of traffic.
And this driving device 25 is provided with the position, be provided in a side of (not shown) on the wheel shaft of front-wheel in early days, supply the rider with foot-operated mode tire on the drive wheels 11 rollings (hereinafter to be referred as front wheel drive type), the bicycle in modern age then is that driving device 25 is located at vehicle frame 10 stage casings (as shown in Figure 1), for the foot-operated trailing wheel 12 (hereinafter to be referred as rear wheel drive) that drives of rider, and this driving device 25 can be described as power transmission again, be responsible for controlling the resistance and the acceleration/accel height that produce when bicycle drives, common rear wheel drive driving device comprises at least: chain wheel set 251 before, the chain 253 of chain wheel set 251 and back movable sprocket group 252 before one back chain wheel set 252 (being called passive chain wheel set again) and at least one drive are above-mentioned, wherein should preceding chain wheel set 251 be formed by the monolithic gear mostly, its two side is provided with a left side, right-hand tread plate 2511,2512, use a left side for the rider, right foot part is the application of force from top to bottom, and this back chain wheel set 252 is to be formed by stacking by the different gear of the multi-disc number of teeth, seeing through chain 253 makes preceding chain wheel set 251 drive the gear of the arbitrary number of teeth on the chain wheel set 252 of back, and then control drives bicycle resistance and acceleration/accel height, for example: when the gear number of teeth of preceding chain wheel set 251 is 48 teeth, when the gear number of teeth of chain wheel set 252 was 16 teeth after chain 253 drove, gear is 1: 3 than then, promptly chain wheel set rotated for 1 week before the expression, 252 3 weeks of rotation of back chain wheel set, produce higher accelerations, relatively, the resistance that is produced when driving is bigger, generally be applicable to and run at high speed or pulsation-free road surface comparatively, on the contrary, when the gear number of teeth of chain wheel set 252 was 24 teeth after chain 253 drove, gear is 1: 2 than then, 251 1 weeks of rotation of chain wheel set before the expression, back 252 2 weeks of rotation of chain wheel set, compared to aforesaid gears than 1: 3, the resistance that drives that is produced certainly will be less, its acceleration/accel is also relatively low and laborsaving, is applicable to the general tool gradient or the bigger ground of resistance.
But, above-mentioned front wheel drive type driver tire, though it is comparatively direct, its shortcoming is: during the rotation direction handle, driving device can rotate synchronously with tire, rider two foots be located at the driving device left-hand tread plate, the distance of right-hand tread plate is bound to, and a side reduces the distance and a side increases distance, just, apart from shortening, the pedal of other side and rider are apart from growth, just the pedal of turn side and rider in the position, when if the axis of orientation steering angle is excessive, tire also can hinder rider one batter portion, causes this batter portion of rider can't the application of force, even causes foot to break away from pedal, so it is not very practical, thereby produced the rear wheel drive driving device, though improvement front wheel drive type driving device disappearance is also found many disappearances under the long-term use:
1. in the process that drives bicycle, to be located between vehicle frame stage casing and trailing wheel because of driving device and to establish, this driving device just is positioned at around the rider foot, easily makes clothing stain the oil stain of sprocket wheel easily.
2. generally speaking, when rider foot forces in driving device, foot fully can't be stretched and force on the pedal, cause rider's application of force limited, when being convenient to the application of force if rider foot is fully stretched, chair cushion on the vehicle frame suitably must be heightened, but this kind mode is very dangerous, easily when bicycle stops, rider foot can't steadily land, and causes roll-over accident.
3. this driving device mainly is the resistance when utilizing gear to drive than size control, just, exchanges the lower resistance that drives for slower acceleration/accel, but this kind mode is crossed in last pond when steep, easily because of application of force deficiency, causes the speed of a motor vehicle to cause car body to topple over excessively slowly.
For this reason, how effectively every disappearance of the above-mentioned driving device of improvement is the problem of studying intensively for the utility model.
