Abstract
The utility model relates to a stepless variable speed device, comprising a driving wheel, a driven wheel, pinions, a pinion shaft and a transmission belt. The utility model is characterized in that a plurality of pinions moving from top to bottom are arranged on the driving wheel; the working radius of the driving wheel can be changed through the movement of the pinions from top to bottom, so that the stepless variable speed purpose can be achieved. The utility model has the advantages that the structure is simple, the utility model does not need a gear box or a clutch, the stepless variable is smooth, and the service power of an engine can be full utilized.
Description
The utility model relates to the stepless speed changes devices on a kind of driver.
At present, the driver on automobile, bicycle, the lathe is to carry out speed change by clutch shift when speed change.This method for changing speed, when gear shift, cooperate bad, fragile gear.
The purpose of this utility model is to produce a kind of stepless speed changes devices, and driver is speed change stably, and resistance is little, and cost of production is low, need not clutch and gearshift.
The utility model is achieved like this, on main driving wheel, be equipped with respectively if in individual small gear, intert on main driving wheel in the axle center of each small gear, and have a slideway movable up and down, driving belt one end to be enclosed within on the driven wheel, and an end is enclosed within on the small gear of driving wheel, driving wheel drives the driven wheel running, when the driven wheel load increases, the drivign belt tension, the compressing pinion shaft is along slideway toward lower slider, make the radius-zoom-out of driving wheel running, thereby play the effect of speed change.
The utility model need not devices such as gearbox and clutch in the running, and the energy automatic stepless speed change is simple in structure, cheap.And speed change is steady, can effectively utilize the use power of motor.
Below in conjunction with accompanying drawing the utility model is further described below.
In the accompanying drawing 1,1 is driving wheel, and 2 is small gear, and 3 is pinion shaft, and 4 is the pinion shaft slideway, and 5 is driving belt, and 6 is driven wheel.On driving wheel 1, several small gears 2 are housed, pinion shaft 3 interts on driving wheel, and can move up and down along slideway 4.Driving belt 5 one ends are enclosed within on the driven wheel 6, one end is enclosed within on the small gear of driving wheel, driving wheel drives driven wheel by driving belt, when the driven wheel load increases, driving belt is tightened, the compressing pinion shaft moves down along slideway, changes the radius of driving wheel rotary work, thereby reaches the self-shifting purpose.
Claims (2)
1, a kind of stepless speed changes devices, it comprises driving wheel 1, small gear 2, pinion shaft 3, driving belt 5, driven wheel 6 is characterized in that having on the main driving wheel several small gears and small gear slideway 4, and pinion shaft interts on driving wheel, and can move up and down along slideway.
2, stepless speed changes devices according to claim 1 is characterized in that driving belt one end is enclosed within on the driven wheel, and an end is enclosed within on the small gear of driving wheel.
