Abstract
The utility model is a motorcycle oil saving single direction rotated driving small chain wheel. The structure is an outer ring gear whose inner circumference is arranged with single direction teeth, at the inside diameter of the outer ring gear, a spline wheel with spline matched with the gear is arranged, on the outer diameter of the spline wheel, a plurality of semi-circle pawl grooves is evenly arranged, inside the pawl groove, a pawl that one end has a movable shaft, the other end is meshed with single direction teeth, matched with the pawl groove is arranged. The pawl is arranged immovably on the wall of the pawl groove through the movable shaft and the tension spring, at the center of the spline wheel, a spline groove is arranged, the groove is matched and installed with the spline shaft on the motorcycle, the oil saving single direction rotated driving small chain wheel is simple and reasonable in structure, easy for installation, low in cost as well as is in favor of popularization and promotion.
Description
Affiliated technical field
The utility model relates to the initiatively unidirectional rotation active of architecture advances, the especially motorcycle fuel-economizing formula minor sprocket of minor sprocket of motorcycle.
Background technique
Present global crude resources shortage, its oil price are constantly soaring, energy saving, and it is more and more important that energy-conserving and environment-protective seem; At present, the driving mechanism of motorcycle is because when reducing throttle, overcome many extra friction, as the friction between each shift gear, the compressive force between piston ring and the piston cylinder etc., thereby shortened the inertia distance of driving a vehicle greatly, virtually waste in vain the energy of fuel oil, this is unfavorable for the purpose of energy saving very much, though also there is the people to transform on the hinge wheel of motor cycle rear wheel, it is reached can unidirectionally rotate, prolong coasting distance, and reach the purpose of fuel-economizing, but the equal more complicated of these structures is installed trouble, cost is bigger, be unfavorable for general application and popularization,, also do not have good solution at present this.
Summary of the invention
When reducing throttle in order to solve motorcycle, thereby overcome many extra friction influences and ride distance, and do not reach the problem of fuel-economizing, the utility model provides initiatively minor sprocket of the unidirectional rotation of motorcycle fuel-economizing formula, and this chain sprocket structure is simple, reasonable, installation is easy, with low cost, help very much popularization and application and popularization.
The concrete scheme that its technical problem that solves the utility model adopts is: this structure comprises outer ring gear 2, spline wheel 8 and ratchet 6 three parts; This structure has an outer ring gear 2 that has unidirectional tooth 1 on interior circle, in the internal diameter of outer ring gear 2, the installation of coupling has the spline wheel 8 of spline 3, on the external diameter of spline wheel 8, evenly have work and do semicircular pawl slot 7, in the pawl slot 7, the end that is equipped with of coupling has movable axis, the other end can with the ratchet 6 of unidirectional tooth 1 engagement, this ratchet 6 is fixedly mounted on the wall of pawl slot 7 by movable axis and tensile spring 5, the center of this spline wheel 8 has spline 3, and this spline 3 is installed with splined shaft 4 couplings on the motorcycle.
During use, this structure is installed on the splined shaft 4 of motorcycle output, and when splined shaft 4 clockwise rotated, order drove spline wheel 8, and ratchet 6 and outer ring gear 2 rotate, and the chain drive motor cycle rear wheel that drives motorcycle rotates and travels; When reducing throttle, splined shaft 4 drives spline wheel 8 and slows down, and with respect to spline wheel 8, outer ring gear 2 still continues former speed and rotates, and this can make the trailing wheel of motorcycle be rotated further, and this also can reach the purpose that continues inertia traveling and reach fuel-economizing.
Its beneficial effect is: the unidirectional rotation of this fuel-economizing formula is minor sprocket initiatively, simple and reasonable for structure, install easy, with low cost, help popularization and application and popularization very much.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and the embodiments;
Accompanying drawing is a structural principle schematic representation of the present utility model;
Among the figure, 1 unidirectional tooth, 2 outer ring gears, 3 splines, 4 splined shafts, 5 tensile springs, 6 ratchets, 7 pawl slots, 8 splines wheel.
Embodiment
In the drawings, outer ring gear 2 is taken turns 8 equal thickness with spline, and the pawl slot 7 that its spline is taken turns on 8 external diameters is more than 2 and symmetry, and is stressed so more even.
In the drawings, be equipped with on the ratchet 6 and can order about the outside all the time open small tension receiving coil spring 5 of ratchet 6, these tensile spring 5 one ends are fixed on the sidewall of pawl slot 7, and the other end withstands on a side of ratchet 6, and it makes ratchet 6 that an outside open power be arranged all the time.
In the drawings, when specifically making this kind minor sprocket, should be at outer ring gear 2 and the spline wheel 8 outside clamping plate of installing, they not only can have been rotated mutually but also can not break away from mutually and fix.
