Abstract
An automatic speed changing wheel is provided, which has simple structure and easy use as well as low manufacturing cost, and can automatically change speed according to different road conditions to achieve the purpose of laboring saving and load reducing. The utility model has a ring wheel, wherein the ring wheel is of chain wheel or belt wheel type, which is characterized in that: a positioning cover is arranged in the center of the ring wheel, and the ring wheel and the positioning cover are connected through an elastic connector.
Description
Technical field
The utility model is particularly related to a kind of automatic speed changing wheel.
Background technique
Existingly run into different road surfaces by chain or bel-drivenn vehicle in the process of moving, should change its chain or bel-drivenn velocity ratio at any time, with the purpose that reaches laborsaving, reduces load.For achieving the above object, overlapping being assembled of wheel sheet that driving wheel and follower all adopt a plurality of numbers of teeth and diameter all not to wait in existing chain or the belt gear.In vehicle driving,, adopt manually control to determine the position of drive chain or belt, and then change chain or bel-drivenn velocity ratio according to the difference of road conditions.This mode of speed regulation complex operation, the transmission part of control drive chain or belt position is fragile, and the manufacture cost of car load is improved.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, and provides a kind of simple in structure, easy to use, can carry out automatic speed changing according to different road conditions, to reach laborsaving, to reduce the load purpose, the automatic speed changing wheel of low cost of manufacture.
The utility model is achieved in that it has an annulus wheel, and described annulus wheel is sprocket wheel or belt pulley, and its special way is: the center in annulus wheel is provided with setting sleeve, connects by Flexible Connector between annulus wheel and the setting sleeve.
Above-mentioned automatic speed changing wheel, said Flexible Connector are by being fixed on 6-8 guide sleeve on the annulus wheel, being located in the guide sleeve and the axis of guide that is connected with setting sleeve, being installed in the spring support on the axis of guide and the spring that is located in the middle part of the axis of guide constitutes.
Above-mentioned automatic speed changing wheel, when annulus wheel was belt pulley, described Flexible Connector was two groups, and was located at the both sides of annulus wheel respectively.
The utility model has the advantages that: simple in structure, easy to use, owing to connect by Flexible Connector between annulus wheel and the setting sleeve, make this automatic speed changing wheel change the size of self taking turns the footpath automatically according to different road conditions, carry out automatic speed changing, can reach laborsaving, reduce the load purpose, and low cost of manufacture.
Description of drawings
Fig. 1 is the utility model (corresponding embodiment's 1) a structural representation;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the utility model (corresponding embodiment's 2) a structural representation.
Among the figure: 1-annulus wheel, 2-setting sleeve, 3-Flexible Connector, 301-guide sleeve, the 302-axis of guide, 303-spring, 304-spring support, 4-end cap.
Embodiment
Embodiment 1
Shown in Fig. 1-2, the utility model has an annulus wheel 1, and described annulus wheel 1 is a sprocket wheel.Be provided with setting sleeve 2 at the center of annulus wheel 1, connect by Flexible Connector 3 between annulus wheel 1 and the setting sleeve 2, described Flexible Connector 3 is by 6-8 the uniform guide sleeve 301 (present embodiment is an example with 6) that is welded on annulus wheel 1 end face, be located in the guide sleeve 301 and constitute by the axis of guide 302 that is threaded and the spring 303 and the spring support 304 at the suit axis of guide 302 middle parts with setting sleeve 2, in guide sleeve 301 outer ends by the end cap 4 that has been threaded.Described spring support 304 and the axis of guide 302 make setting sleeve 2 be positioned at annulus wheel 1 center by being threaded by adjusting spring seat 304.
During use, this automatic speed changing wheel is installed on the bicycle crank as drive sprocket, and distend wheel is set below driven sprocket.When bicycle running in when upward trend, the resistance of riding increases, the tension force of chain is along with increase, the automatic speed changing wheel changes the size of self taking turns the footpath automatically under the effect of chain, at this moment, corresponding annulus wheel 1 is compressed with the spring 303 of chain interlock place, all the other springs 303 stretch, annulus wheel 1 and setting sleeve 2 off-centre, chain can not relax under the effect of distend wheel, thereby reaches the self-shifting purpose.
Embodiment 2
As shown in Figure 3, the utility model has an annulus wheel 1, and described annulus wheel 1 is a belt pulley.Be provided with setting sleeve 2 at the center of annulus wheel 1, connect by Flexible Connector 3 between annulus wheel 1 and the setting sleeve 2, described Flexible Connector 3 is two groups and lays respectively at annulus wheel 1 both sides, every group of Flexible Connector 3 is the guide sleeves 301 that are welded on annulus wheel 1 end face by uniform, be located in the guide sleeve 301 and constitute by the axis of guide 302 that is threaded and the spring 303 and the spring support 304 at the suit axis of guide 302 middle parts with setting sleeve 2, by the end cap 4 that has been threaded, described spring support 304 and the axis of guide 302 are by being threaded in guide sleeve 301 outer ends.
During use, this automatic speed changing wheel is installed on petrol engine or the diesel engine as driving wheel, and distend wheel is set, when vehicle driving in when upward trend, running resistance increases, the tension force of belt is along with increase, the automatic speed changing wheel changes the size of self taking turns the footpath automatically under the effect of belt, at this moment, corresponding annulus wheel 1 is compressed with the spring 303 of belt contacting point, and all the other springs 303 stretch annulus wheel 1 and setting sleeve 2 off-centre, belt can not relax under the effect of distend wheel, thereby reduces the load of petrol engine or diesel engine.
