Abstract
The utility model discloses a speed-changing skidding wheel, which comprises an outer gear plate, a core shaft and a pressing cover. A detent and a spring are arranged on the outer wall of the core shaft. A ball cavity is arranged between the outer gear plate and the core shaft and the pressing cover. A circle of balls are uniformly arranged in the ball cavity. So, when the motor of a motorcycle is stopped, the rear wheel of the motorcycle makes the motorcycle skid continuously under the inertia effect, moreover the friction force between the outer gear plate and the core shaft and the pressing cover is very small because of the effect of the balls, thus the motorcycle can skid for a relatively long distance and is very convenient. Furthermore, because a cylindrical spring is adopted by the speed-changing skidding wheel, the strength of the spring is increased, thus the speed-changing skidding wheel is provided with characteristics of small friction force, hard-wearing and long working life.
Description
Technical field
The utility model relates to a kind of motorcycle part, especially relates to the transmission device of motorcycle.
Background technique
What the speed-change sliding wheel in the transmission device adopted behind the motorcycle at present is one-way clutch, wherein is processed with saw shape tooth on the inwall of external tooth wheel disc, and ratchet and spring are housed in the outside diameter of mandrel, and this ratchet matches with saw shape tooth.This structure can make motorcycle in travelling when killing engine, and this engaging and disengaging gear makes motor cycle rear wheel continue to slide forward under action of inertia, reduces machine members and energy-conservation effect to reach.But the speed-change sliding of this structure wheel in the running, and frictional force is bigger mutually between the inwall of external tooth wheel disc and the outer wall of mandrel, therefore shortens the distance that motorcycle slides, and long-term use of this speed-change sliding wheel is easy to damage.
The model utility summary of the invention
The purpose of this utility model be to provide a kind of frictional force little, slide light speed-change sliding wheel.
The utility model is achieved through the following technical solutions:
A kind of speed-change sliding wheel comprises external tooth wheel disc, mandrel and gland, and ratchet and spring are housed on the outer wall of mandrel, is provided with the ball chamber between external tooth wheel disc and mandrel and the gland, all is equipped with all balls in the ball chamber.
Described external tooth wheel disc outside is a straight-tooth.
Described external tooth wheel disc outside is a helical teeth.
Described external tooth wheel disc outside is a sprocket.
Described ball chamber is, the inwall of gear disk is positioned at place, saw shape tooth both sides outside respectively all concave arcs, when external tooth wheel disc 1 is installed together with mandrel 3 and gland 4, wherein form the ball chamber with all concave arc of its corresponding section on all concave arcs and the mandrel outer wall, on another all concave arc and the gland with all concave arc formation balls chamber of its corresponding section.
Spring is a helical spring, is provided with the structure that makes its location in the bottom of spring, and the center line MN of spring is with to cross it perpendicular with the tangent line QM of the interior circular arc intersection point of ratchet.
The position structure of spring bottom is the groove that is complementary with the spring outside dimension.
The position structure of spring bottom is the projection that is complementary with spring inside diameter, and this protruding height is less than 1/2 of spring length.
Speed-change sliding wheel of the present utility model is owing to be provided with two all balls between external gear and mandrel and gland, motorcycle is when motor quits work like this, trailing wheel makes motorcycle continue to slide forward under effect of inertia, and under the effect of ball between external tooth wheel disc and mandrel and the gland frictional force very little, make motorcycle can slide longer distance, very light.Because this speed-change sliding wheel has adopted helical spring, increased the intensity of this spring again.Therefore this speed-change sliding wheel has the advantages that frictional force is little, durable, the life-span is long.

Embodiment
Embodiment 1:
External tooth wheel disc 1 outside is contained in the outside of mandrel 3 and gland 4 for straight-tooth, gland 4 screws on mandrel 3, be positioned at place, saw shape tooth 7 both sides outside on gear disk 1 inwall one all concave arcs are respectively arranged, when external tooth wheel disc 1 is installed together with mandrel 3 and gland 4, wherein all concave arcs on all concave arcs and mandrel 3 outer walls formed all concave arcs on ball chamber 8 another all concave arcs and the gland 4 formed ball chamber 8 ', in ball chamber 8,8 ' interior all the balls 2 that are equipped with respectively, 2 ', be evenly distributed with a plurality of saw shape teeth 7 outside on the inwall of gear disk 1, ratchet 5 and spring 6 are housed on the outer surface of mandrel 3, and it is perpendicular that the tangent line QM of circular arc intersection points in the ratchet 5 is crossed in the center line MN of this spring 6 and it.Be provided with the structure that makes its location in spring 6 bottoms, this position structure is out the groove 10 on mandrel 3 in the present embodiment, and fluted 10 internal diameters of spring 6 outside dimensions are complementary.
External tooth wheel disc 1 outside of present embodiment also can be helical teeth.
During use speed-change sliding wheel is contained on the final stage axle and final stage axle spline fitted.Motorcycle transmission part when cruising drives the rotation of speed-change sliding wheel moves ahead motorcycle, and when motorcycle engine quit work, car body can make motorcycle continue to slide forward under action of inertia, and can slide longer distance.
Embodiment 2:
Present embodiment and embodiment's 1 structure is basic identical, and its difference is that described external tooth wheel disc 1 outside is sprocket.The position structure of spring 6 is the projectioies 11 that are complementary with spring 6 internal diameters, and the height of this projection 11 should be less than 1/2 of spring 6 length.
