Abstract
The utility model relates to a stepless speed variator for a bicycle; three uniformly distributed planet wheels are engaged at the outside of a driven wheel in the speed variator, and the planet wheels are engaged with the inner ring teeth of a friction wheel; the edge of the friction wheel is provided with a speed controller; the purpose of variable speed is achieved by controlling the rotation speed of the friction wheel through adjusting the controller by a rotary handlebar; the number of gears is a few compared with the universal poking chain gear set speed variator, the manufacture is easy, the stepless gear can be achieved, and the operation is easy.
Description
The utility model relates to a kind of bicycle use toric transmission.
Usually derailleur adopts and dials articulated gear group speed change, and this change-speed box is many with gear, and speed change will be stirred chain, the processing and manufacturing complexity, and speed change can only have several class.
The purpose of this utility model is to provide a kind of bicycle use toric transmission, and is reasonable in design, simple structure, and processing and manufacturing is easy, and speed change can be accomplished stepless change, and is easy to operate.
In conjunction with the accompanying drawings 1,2, the utility model is achieved in that in follower 13 external toothings three uniform satellite gears 6, and satellite gear is meshed with the inner circular tooth 7 of frictional wheel 1 again.Satellite gear is positioned on lining plank 4 and the follower base 5 by screw.There is a rotational speed governor 11 at the frictional wheel edge.Outer casing 19 is tightened on the follower by screw thread.Steel ball 2 is arranged between frictional wheel and outer casing, rotate freely to guarantee frictional wheel.Inner casing 18 is fixed on the frictional wheel by screw 3.Follower is tightened on the gearbox adapter by gland 12.
As shown in Figure 3, rotational speed governor is to see accompanying drawing 4 by friction clamp 14 with by the handle 15(that is installed on the handlebar on the frictional wheel) and anchor fitting 8(see accompanying drawing 5) and the backguy 9 that connects the voussoir in the controller 10 is formed by connecting.
Anchor fitting is made up of with backguy ratchet 16, ratchet 17.
According to the bicycle use toric transmission that said structure is made, inner core simultaneously tightens on the bicycle freewheel, and another side tightens on the floral disc of bicycle rear.When flywheel rotates under chain drive, drive the change-speed box inner core and rotate, inner core and floral disc are become one, so floral disc and inner core are done to rotate synchronously, promptly whole trailing wheel rolls forward.When tightening handle, backguy spurs voussoir, makes friction clamp be close to frictional wheel, and the control rotating speed of frictional wheel and satellite gear be thereupon by gradually fast slowly, clamped when motionless by friction clamp fully when frictional wheel, and satellite gear rotates the fastest, make the follower rotating speed the highest, reach the purpose of regulating speed change.This project organization compactness, processing and manufacturing is easy, accomplishes stepless change.According to bicyclist's speed change request, by the ratchet on the anchor fitting, be controlled at any time in a certain speed range and operation freely.
