Abstract
The utility model discloses a bicycle which is composed of a bicycle frame (1), pedals (2) and bicycle wheels (3). The lower part of the bicycle frame (1) is provided with a support bracket (5), one end of the support bracket (5) is provided with a pedaling driving axle (6), and the other end of the support bracket (5) is provided with a bicycle wheel driving axle (7). The pedaling driving axle (6) and the bicycle wheel driving axle (7) are also connected by a transmission device which is a gear transmitting device. After the utility model is used, a chain can be effectively prevented from disconnecting and being broken. The utility model uses a gear with more teeth to drive a gear with less teeth to increase the riding speed. The gear transmitting device of the utility model adjusts the speed by adjusting the tooth number ratio among the gears which are mutually engaged. A rotating axle is a resistance preventing sleeve axle. Frictional force between the rotating axle and the support bracket can be decreased, and the resistance in the transmission of transmitting gears can be decreased.
Description
Technical field
The utility model relates to a kind of bicycle.
Background technology
Between two pedals of present ordinary bicycle and the center of trailing wheel all is provided with sprocket wheel, between two sprocket wheels by chain gear, chain is sent to the prime power of pedal on the sprocket wheel of trailing wheel, and sprocket wheel drives bicycle rear and rotates, and falls chain and chain rupture in the process of travelling easily.Because car speed that prime power produces in the process of travelling and variation are very little, relatively require great effort when riding.
Summary of the invention
The utility model provides a kind of bicycle, and it directly adopts gear transmission, is difficult for falling chain in the process of transmission, and is more laborsaving when riding.
The utility model is by the following technical solutions: a kind of bicycle, form by vehicle frame, pedal and wheel, support is arranged at the bottom of vehicle frame, one end of support is provided with the pedal axle drive shaft, the other end is a wheel drive shaft, also be connected with driving device between pedal axle drive shaft and wheel drive shaft, described driving device is a gear system.
Described gear system comprises driving gear, transmission gear and driven wheel, described driving gear is fixedly mounted on the pedal axle drive shaft, described transmission gear is rack-mount by rotating shaft, transmission gear is a dual gear, described driven wheel is installed on the wheel drive shaft, one gear of dual gear is meshed with driving gear, and another gear is meshed with driven wheel.
In the described dual gear with the number of teeth of driving gear mating gear less than and diameter be less than driving gear, with the number of teeth of driven wheel mating gear greater than and diameter more than driven wheel.Described rotating shaft is anti-resistance sleeve.
After adopting the technical program, but actv. prevents chain and chain rupture.Speed when the utility model is ridden by the less gear raising of the more gear drive number of teeth of the number of teeth.Gear system of the present utility model is recently regulated the speed by the number of teeth of adjusting between pitch wheel.Rotating shaft can reduce the friction force between rotating shaft and the support, the resistance when reducing the transmission gear transmission for anti-resistance sleeve.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
In Fig. 1, the utility model comprises pedal 2, wheel 3 and vehicle frame 1, the bottom of vehicle frame 1 is a support 5, one end of support 5 is provided with pedal axle drive shaft 6, the other end is provided with wheel drive shaft 7, be installed with driving gear 8 on the pedal axle drive shaft 6, the number of teeth of driving gear 8 is 105 teeth, and diameter is 320mm, wheel drive shaft 7 is arranged on the center of rear wheel, be installed with driven wheel 9 on wheel drive shaft 7, the diameter of driven wheel 9 is 170mm, is provided with transmission gear between driving gear 8 and driven wheel 9, transmission gear is installed on the support 5 by anti-resistance sleeve 10, transmission gear is a dual gear, and the diameter of the gear 11 in the dual gear is 170mm, and the number of teeth is 56 teeth, it is meshed with driving gear 8, the diameter of another gear 4 is 270mm, and the number of teeth is 90 teeth, and it is meshed with driven wheel 9.The utility model foot-operated axle drive shaft 6 in the process of riding drives driving gear 8 and rotates, the gear 11 that driving gear 8 drives in the dual gear rotates, increase at this transmission process medium velocity, another gear 4 of dual gear also rotates, it drives driven wheel 9 and rotates, process medium velocity in this transmission further increases, thereby reaches the purpose of speed-raising.
