Abstract
The utility model discloses a footboard type bicycle which comprises a frame, a front wheel, a rear wheel and a face plate rotationally connected with the rear wheel through a driving chain. The face plate is fixedly arranged on a speed increasing middle shaft which is fixedly provided with a speed increasing chain wheel, and the speed increasing chain wheel is rotationally connected with a footboard middle shaft chain wheel arranged in the middle of the footboard middle shaft through the driving chain; the footboard middle shaft is transversely installed on a bracket, two end parts of which are fixedly provided with a ratchet gear wheel composed of a ratchet gear cylinder and a plurality of composite ratchet cores, wherein, the ratchet gear cylinder is respectively provided with a left footboard and a right footboard between which a steel cable is connected, and the steel cable is arranged inside a pulley slot of a fixed pulley which is arranged between the left and the right footboards. The footboard type bicycle has reasonable structural design, accords with the ergonomic, saves effort for riding and has rapid speed.
Description
Technical field
The utility model relates to a kind of bicycle, particularly a kind of pedal-type bicycle.
Background technology
Bicycle is a kind of vehicle that people often use, and pattern is various, yet its type of drive adopts foot-operated crank driving mechanism mostly.Because the mechanical structure of said mechanism is unreasonable, so people are in the middle effort of riding, and speed is slow and vehicle body heavy.
The utility model content
The purpose of this utility model is at the existing in prior technology deficiency, and a kind of in light weight, laborsaving and speed pedal-type bicycle faster is provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pedal-type bicycle, comprise vehicle frame, front-wheel, trailing wheel and the floral disc that is rotationally connected by chain drive-belt and trailing wheel, it is characterized in that: described floral disc is fixedly mounted on the speedup axis, be positioned at and be installed with the speedup sprocket wheel on the speedup axis, the speedup sprocket wheel is connected with the pedal axis sprocket rotation that is arranged on pedal axis middle part by driving chain; Described pedal axis is laterally rack-mount, its both ends are installed with the left and right sides ratchet-gear wheel of being made up of the ratchet tube, be positioned at left-hand tread plate and right-hand tread plate are installed respectively on the ratchet tube, be connected with cable wire between described left-hand tread plate and the right-hand tread plate, cable wire is arranged in the race of fixed pulley, and fixed pulley is arranged on the centre of left-hand tread plate and right-hand tread plate.
The utility model compared with prior art has the following advantages: the utility model reasonable in design, meet ergonomics, and it is laborsaving to ride, and speed is quick, and tare is light.
