Abstract
The utility model discloses an automatic-accelerated tandem bicycle and relates to a bicycle. The automatic-accelerated tandem bicycle comprises a frame, a front driving mechanism and a rear driving mechanism. The front driving mechanism comprises a first chain wheel and a treading mechanism. The treading mechanism is connected to the first chain wheel in a matched mode, the first chain wheel is rotationally fixed to the frame, one end of a bicycle rear axle is provided with a first fly wheel, and the first chain wheel is in transmission connection with the first fly wheel through a chain. The rear driving mechanism comprises a second chain wheel, a second fly wheel, a third fly wheel, a fourth fly wheel and a rear treading mechanism. The second chain wheel is fixed to the bicycle rear axle through a bearing, the second fly wheel is fixed to the bicycle rear axle, the third fly wheel is fixed to the frame above the second chain wheel through a rotating shaft, the fourth fly wheel and the third fly wheel are arranged on the same rotating shaft, the second chain wheel is connected with the third fly wheel in a rotating mode through a chain, and the fourth fly wheel is connected with the third fly wheel in a rotating mode through a chain. According to the tandem bicycle, riding is easy and fast, the structure is simple, and manufacturing is easy.
Description
Technical field
The utility model relates to a kind of bicycle, particularly a kind of double or bicycle that many people ride.
Background technology
Existing tandem bicycle, while riding, two people ride and need exert oneself simultaneously, and need basically identical harmony, ride and comparatively consume power, riding speed is slow, and double-legged actuating speed is limited, cause riding speed lower, generally, below 20 km/h, therefore, people ride Electrical Bicycle or motor bike etc. for pursuit speed often changes, but the storage battery of Electrical Bicycle can cause environmental pollution, motor bike to need these non-renewable resources of fuel consumption.
Utility model content
The utility model object is to provide a kind of and rides easily, simple in structure, manufactures and is easy to from the many person bicycles of speedup.
The utility model comprises vehicle frame, front driving mechanism, rear drive mechanism, described front driving mechanism comprises the first chain wheel, stampede body, described stampede body is connected on described the first chain wheel, described the first chain wheel is turnably fixed on described vehicle frame, in one end of back wheels of vehicle axle, the first flywheel is set, described the first chain wheel is in transmission connection by chain and described the first flywheel, described rear drive mechanism comprises the second chain wheel, the second flywheel, the 3rd flywheel, the 4th flywheel, rear stampede body, described the second chain wheel is fixed on back wheels of vehicle axle by bearing, described the second flywheel is fixed on back wheels of vehicle axle, described the 3rd flywheel is fixed on the vehicle frame of described the second chain wheel top by rotating shaft, described the 4th flywheel and described the 3rd flywheel are arranged in same rotating shaft, described the second chain wheel is rotationally connected by chain and described the 3rd flywheel, described the 4th flywheel is rotationally connected by chain and described the 3rd flywheel, a crank and described second chain wheel of described rear stampede body are fixed, after another crank and car, the other end of rotating shaft is fixed.
When the utility model is used, bicyclist above rotates the first chain wheel by stepping on stampede body, and the first chain wheel drives the first flywheel to rotate, and it is that car moves ahead that the first flywheel drives trailing wheel to rotate, bicyclist below drives the second chain wheel to rotate by stampede body after stepping on, the second chain wheel drives the second flywheel to rotate, because the 3rd flywheel and youngster's flywheel coaxially arrange, therefore the 3rd gear also synchronously rotates, the 3rd flywheel drives the 4th flywheel to rotate, because the diameter of the second chain wheel is greater than the diameter of the second flywheel, the second flywheel speed is very fast, the 3rd flywheel obtains the speed identical with the second flywheel, the 4th flywheel with the 3rd flywheel by chain gear also obtains speed faster, the 4th flywheel drive trailing wheel moves ahead and reaches acceleration effect, these many person bicycles are ridden easily, fast, simple in structure, easy to manufacture.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to view.
The specific embodiment
As shown in Figure 1, 2, a kind of from the many person bicycles of speedup, comprise vehicle frame 1, front driving mechanism 2, rear drive mechanism 3, front driving mechanism 2 comprises the first chain wheel 4, stampede body 5, stampede body 5 is connected on the first chain wheel 4, the first chain wheel 4 is turnably fixed on vehicle frame 1, the first flywheel 7, the first chain wheels 4 is set in one end of back wheels of vehicle axle 6 and by chain and the first flywheel 7, is in transmission connection, rear drive mechanism 3 comprises the second chain wheel 8, the second flywheel 9, the 3rd flywheel 10, the 4th flywheel 11, rear stampede body 12, the second chain wheel 8 is fixed on back wheels of vehicle axle 6 by bearing, the second flywheel 9 is fixed on back wheels of vehicle axle 6, the 3rd flywheel 10 is fixed on the vehicle frame 1 of the second chain wheel 8 tops by rotating shaft, the 4th flywheel 11 and the 3rd flywheel 10 are arranged in same rotating shaft, the second chain wheel 8 is rotationally connected by chain and the 3rd flywheel 10, the 4th flywheel 11 is rotationally connected by chain and the 3rd flywheel 10, crank of rear stampede body 12 and the second chain wheel 8 are fixing, after another crank and car, the other end of rotating shaft 6 is fixed.
Existing Electrical Bicycle also can adopt structure of the present utility model to transform, and the Electrical Bicycle after improvement can be saved electric power, and charge frequency reduces, and has saved the energy; Expansion by this technology is used, and the lead-acid battery that accelerates battery-driven car improves, develops to lithium cell, fundamentally reduces water and soil and pollutes.
