Abstract
The utility model relates to a chainless fast bicycle which is composed of a bicycle frame, a transmission part and a steering part, wherein the transmission part of the utility model is provided with a base on the bicycle frame, a gear is arranged on the base and the front part of the gear is provided with a free wheel type gear. The gear is connected with transmission rod through a transmission shaft, and the transmission rod is connected to a movable rod at the back part of a telescopic device through the connecting rod of the telescopic device on which a boosting rod and a fixing rod are arranged. When the utility model is ridden, the boosting rod is trod by feet, the front end of the boosting rod is downwards moved around a support rod circular in a circular arc of 180 DEG to drive a connecting rod of the telescopic device so that a shaft of the movable rod is pushed to move forwards; furthermore, the connecting rod of the telescopic device and the transmission rod are pushed to move forwards, the gear and the free wheel type gear are driven to engage with each other and then the forwards running motion is accomplished. The utility model has the advantages of high riding speed and labor saving.
Description
The utility model belongs to the design and the manufacturing technology field of bicycle.
At present, the employed bicycle of people is to be made of vehicle frame, running part and knuckle section.Its running part has speed change and coventional type car again.Derailleur and common car all are to be driven by chain.Structure is comparatively complicated, and riding speed is also relatively slow.
The purpose of this utility model provides a kind of no chain, and has the bicycle of pipe expansion joint, and it is very fast relatively to ride.Save time, laborsaving.
Structure of the present utility model as shown in drawings; Be made of running part, knuckle section and vehicle frame, its knuckle section is the same with ordinary bicycle.Its vehicle frame (13) is an one, adopts the packaging type structure of motor bike.The structure of its running part is; One base (21) is arranged on vehicle frame, a gear wheel shaft is arranged on base, have gear (22) on gear wheel shaft, on the gear wheel shaft next door one transmission shaft (23) is arranged, connect a drive link (24) on the transmission shaft, drive link connects pipe expansion joint link rod (26) through movable axis (25).One link rod anchor shaft (27) and movable axis (28) are arranged in pipe expansion joint link rod bottom, and the pipe expansion joint link rod is on the portable bar (1) on these two axles connection pipe expansion joints (A).In gear (22) front portion one flywheel-type gear (20) is arranged, two-wheeled is meshing with each other, and the axle of flywheel-type gear is rear axle of the present utility model.The structure of its pipe expansion joint (A) as shown in Figure 2; Have a center shaft (8) on base (21), be with a bearing (7) on the center shaft, there is a bearing carrier ring (6) the bearing outside, and the outside of bearing carrier ring is bearing seat (9).One fixed link coupking shaft (5) is arranged on bearing seat, a brace rod (3) is arranged in the above.Form fixed link (10) by bearing seat (9), fixed link coupking shaft (5) and brace rod (3).Fixed link is by being bolted on the base.One portable bar (1) is arranged at the pipe expansion joint rear portion, and portable bar connects brace rod (2) through movable axis.The movable axis other end has brace rod (3), and brace rod (3) is associated on the fixed link coupking shaft (5), and brace rod (2) is bound up on the boosting-rod coupking shaft (4).Boosting-rod coupking shaft (4) is fixed on the bearing outside (6).Have boosting-rod (15) on its coupking shaft.Boosting-rod is fixed on the bearing outside by nut (11).On boosting-rod (15) tilting bearing is arranged, connect a pole (14) through this bearing, pole (14) lower end has a movable axis and anchor shaft, and anchor shaft is fixed on the vehicle frame.One power wheel (17) is arranged on vehicle frame top, have driving band (16) on the power wheel.Have brake (18) on the wheel rear axle.There is an activity to join bar (29) with portable bar (1) respective side.
Course of action of the present utility model is; When the people rides, be with foot-operated moving boosting-rod (15), at this moment, the boosting-rod front end serves as the axle motion with pole (14) downwards, is 180 ° of circular arc actions.The brace rod (2) and the brace rod (3) that drive pipe expansion joint move to fixed link coupking shaft (5), promote portable bar (1) and move backward, and portable bar promotes pipe expansion joint link rod (26) action through movable axis (28), link rod anchor shaft (27) again.Because portable bar (1) moves backward, because the effect of link rod anchor shaft (27) travels forward drive link (24), driven gear (22) turns round, and gear (22) drives the flywheel-type gear and travels forward, and moves ahead thereby promote the pavilion body.
The utility model is owing to adopting gear transmission, with the car body of making a concerted effort to drive of boosting-rod and fixed link.Act on foot-operated power on the boosting-rod according to measuring and calculating, can reach three times of the foot-operated power of ordinary bicycle, so riding speed is fast, and laborsaving.
