Abstract

The utility model relates to a double chain shock-absorbing high speed bicycle which belongs to the technical field of vehicles used for daily life by families. The utility model is characterized in that a fly chain wheel is arranged between a chain wheel and a flywheel and is a combination of the flywheel and the chain wheel; the fly chain wheel is fixed on a bicycle frame, can rotate freely, and is connected with the chain wheel and the flywheel respectively through two chains; a T-shaped iron pipe sheathed with a spring from outside is arranged below a saddle, inserted from the lower end of a connecting vertical hole of the bicycle frame and then connected with a cloth hanger, a connecting point is movable and rotatable, and a connecting point between the cloth hanger and the bicycle frame is movable. Therefore, the saddle can spring back automatically after is pressed and can not rotate from left to right. When the novel bicycle is used, the fly chain wheel and double chains transmit the pedaling force of a rider together to drive a rear wheel to rotate at high speed and thus to improve the speed of the bicycle. The bicycle is provided with a shock-absorbing type saddle, so the shock of a human body and a brain can be avoided effectively, and the goal of protecting the brain is achieved.

Description

Double-stranded damping type high-speed bicycle

The utility model belongs to Family Day and uses technical field of transportation means.

The prior art close with the utility model is traditional bicycle.Because this bicycle adopts the transmission of strand bar, the speed of a motor vehicle is quite slow, loses time, and Uneven road causes the vehicle body vibrations in addition, causes the concussion of human body and brain, brings discomfort to health.

Task of the present utility model provides a kind of double-stranded bar acceleration device that flies sprocket wheel that is equipped with, and is furnished with the new bicycle of damping type saddle.

The utility model is to realize like this, between sprocket wheel 1 and flywheel 3, establish one and fly sprocket wheel 2, this flies sprocket wheel is that small flywheel and hinge wheel are fixed together, and be installed on the vehicle frame, make it free to rotate, the small flywheel that flies in the sprocket wheel 2 is connected with sprocket wheel 1 with chain 4, and hinge wheel is connected with flywheel 3 with chain 5, transmit rider's pedal power by flying sprocket wheel 2, drive the trailing wheel high speed rotating.

The damping type saddle of this utility model bicycle is such design-calculated, divides into the T sections pipe 7 that an outside is with spring at saddle 6, and penetrates in the joint vertical core 10 of vehicle frame, and it can be rebounded after pressing saddle, unclamping automatically.Saddle 6 is the point of connection of living with the point of connection of clothes hanger 8 simultaneously, and the point of connection 9 of clothes hanger 8 and vehicle frame can move up and down saddle for the point of connection of living, and prevents left-right rotation.By above innovation the speed of a motor vehicle is improved more than 40%, can effectively prevent the concussion of human body and brain, and have make simple, easy for operation, safe and reliable, advantage such as speed is fast.

Accompanying drawing is that the utility model is applied in a making embodiment on family's traffic tool bicycle:

As shown in Figure 1: 1 is sprocket wheel, 2 for flying sprocket wheel, and 3 is flywheel, and 4 is chain, 5 is chain, 6 is saddle, and 7 is T sections pipe, and 8 is clothes hanger, 9 are the point of connection of living, 10 is the joint vertical core of vehicle frame, framework of the present utility model, and front and back wheel, front and rear brake, antero posterior axis, chain, saddle, handlebar are identical with traditional bicycle.Fly the combination of sprocket wheel 2 for small flywheel and hinge wheel, be installed in the middle of sprocket wheel 1 and flywheel 3, free to rotate, to fly small flywheel and hinge wheel in the sprocket wheel 2 with two chains, be connected with flywheel 3 with sprocket wheel 1 respectively, drive the trailing wheel high speed rotating by the foot-operated power of transmitting the rider, F-Zero can reach 25 to 30 kilometers.T sections pipe 7 inserts the outer foldable type of iron pipe one end from the connection vertical core lower end of vehicle frame, T sections pipe 7 outsides are with spring, the upper end is upper saddle seat 6 fixedly, is connected with clothes hanger 8, and this point of connection is mobilizable, prevent the saddle left-right rotation, make saddle after pressing, can rebound automatically.

Claims

1, a kind of double-stranded damping type high-speed bicycle, it is characterized in that establishing one on the vehicle frame between sprocket wheel 1 and the flywheel 3 flies sprocket wheel 2, be connected with flywheel 3 with sprocket wheel 1 with two chains respectively, this flies the secure bond body that sprocket wheel 2 is small flywheel and hinge wheel, is free to rotate.

2, double-stranded damping type high-speed bicycle according to claim 1, it is characterized in that: saddle 6 is divided into a T sections pipe 7, insert connection vertical core 10 bottoms by vehicle frame, the T sections pipe 7 outer springs that are with, together firm with saddle, be connected with clothes hanger 8 simultaneously, this point of connection and clothes hanger are rotating point of connection alive with the point of connection 9 of vehicle frame, saddle can be upspring after pressing, prevent the saddle left-right rotation.
