Abstract
Disclosed is an automatic clutch for a motorcycle, which is used for gliding fuel saving of the 50 series motorcycles. A coaxial star wheel is arranged in an outer hub integrated with the last stage gear in a decelerating box, and both sides of the notches evenly arranged along the circumference of the coaxial star wheel have different distances to the inner annular surface of the outer hub. Cylindrical notch bores are vertically arranged on the longer side of the notches, and the spring in a notch bore is connected with the rolling body in a notch. Penetrating the last stage gear and the shaft hole of the star wheel, the shaft connected with a driving wheel is movably coupled with the star wheel. The utility model has the advantages of simple structure, solidity, durability and 30% reduction of fuel consumption per 100 km.
Description
The utility model relates to a kind of transmission device of motorcycle, especially for the sliding fuel-saving device of 50 serial light cavalry motorcycles.
Having narrated a kind of " the automatic slide device of motorcycle " in the utility model patent (application number 89207420.5) its objective is and provide a kind of rotating machinery and driving wheel of 50 series motorcycles transmission system when sliding of making to throw off automatically, and when non-sliding, can make their automatically sealed devices, its formation is that the inner ring surface of final stage gear-wheel gear-ring in speed reducer is provided with circumferentially uniform ratchet, its with in establish radial symmetric setting on the mandrel outer connector of keyway ratchet be complementary, its deficiency is that ratchet very easily damages.
In view of above-mentioned deficiency the purpose of this utility model of the prior art is to provide a kind of durable sliding fuel-saving device that is installed on the 50 serial light cavalry motorcycles.
The purpose of this utility model can realize by following measure: a kind of Motorcycle Automatic Clutch that is used for 50 series motorcycle sliding fuel-economizings, it is characterized in that with speed reducer in the circumferentially uniform groove both sides of coaxial star-wheel in the outer hub that combines as a whole of final stage gear do not wait to the degree of depth of star-wheel exterior edge face, the groove side of a darker side is provided with the cylinder slotted eye, the hole inner spring can join with the rolling element in the groove, the axle that links to each other with driving wheel passes star-wheel final stage gear and axis hole and connects with star-wheel is movable, and preferably being located at the interior rolling element of star-wheel groove is roller.
The utility model mainly is on the final stage gear in speed reducer free wheel device to be set.It mainly is made up of parts such as outer hub, star-wheel, rolling element, cover plate, spring and ejector pins.
The outer field gear ring of gear of the present utility model is identical with the gear ring of final stage gear in the 50 series motorcycle speed reduceres, so that do not change the structure of the coupled original parts of motorcycle.For bearing the motorcycle bigger torsional moment that is in operation, gear ring and former are connected as a single entity.Also be provided with the outer hub of the axial cylindrical housing shape that combines as a whole with it in a side of this gear.Be somebody's turn to do the diameter of the internal diameter of outer hub, make star-wheel can be positioned at it greater than the star-wheel exterior edge face.Star-wheel is uniform groove circumferentially, and it is preferably four, does not wait as the distance of the wedging plane at the bottom of the groove to outer hub inner ring surface in the groove, makes the radial section of groove and the folded part of outer hub inner ring surface be wedge shape.Does not wait to the distance of star-wheel exterior edge face same groove both sides, wherein the groove side of long side is provided with the cylinder slotted eye of vertical this face, slotted eye is built-in with a spring, it can join with the rolling element that is located in the groove, preferably this rolling element is a cylindrical body, and its diameter is a bit larger tham outer hub inner ring surface to the shortest distance in wedging plane.Can pass the transmission shaft that links with driving wheel in the axis hole of star-wheel, both are movable to connect.It can be to be provided with in the axis hole and the spline that is complementary of axle upper spline, also can be provided with on the spider gear shaft outer end of hole face with axle on the protruding key that is complementary of prominent key.
Belt drives gear rotations at different levels in the speed reducer when motorcycle is kept in motion, then also rotation thereupon of the outer hub of final stage gear.Push the rolling element in the groove to a spring opposite side under frictional force action, make its automatic wedging, realize sealedly automatically, the final stage gear and the star-wheel at then outer hub place are connected as a single entity, and moment of torsion is passed to driving wheel.When being in sliding state for motorcycle, belt and speed reducer transmission shaft are thrown off driving wheel and are driven star-wheel by transmission shaft.Push the rolling element in the groove to spring one side under the effect of frictional force, the wedging face that makes rolling element leave outer hub inner ring surface or star-wheel is realized throwing off automatically, and then star-wheel and driving wheel rotate synchronously, and the final stage gear is transfixion then.When sliding state finished, spring was pushed into rolling element again and outer hub inner ring surface and star-wheel wedging face position contacting, to keep the rolling element proper functioning.
Drawing is described as follows:
Fig. 1 is an assembling schematic representation of the present utility model.
Fig. 2 is the schematic side view of the utility model middle gear.
Fig. 3 is the front elevational schematic of star-wheel in the utility model.
Fig. 4 is the schematic side view of star-wheel in the utility model.
The utility model is described in further detail to utilize the example shown in the accompanying drawing:
In the schematic side view of Motorcycle Automatic Clutch middle gear shown in Figure 2, the outer field gear ring 1 of gear is identical with the gear ring of 50 series motorcycle speed reducer final stage gears, and is connected as a single entity with the disc of gear.On this gear, also be provided with and be connected as a single entity with it and perpendicular to hub 2 outside its disc coaxial.
In the front elevational schematic of Motorcycle Automatic Clutch star-wheel shown in Figure 3, the exterior edge face of star-wheel 3 is provided with four circumferential uniform grooves, does not wait to the distance of star-wheel exterior edge face the groove both sides, and wherein the groove side of long side is provided with the cylinder slotted eye 4 of vertical this end face, as shown in Figure 4.Be provided with six circumferential uniform splines 5 that are complementary with the transmission shaft upper spline in the star-wheel axis hole.
In the assembling schematic representation of Motorcycle Automatic Clutch shown in Figure 1, the groove on the star-wheel cylinder is built-in with roller 8.Itself and a spring 6 that is located in the cylinder slotted eye join by ejector pin 7.The outer ring surface of hub is provided with end cap 9 outside, and it is fixed on the outer hub by coupling.
The utlity model has following advantage:
1. sliding performance is good, but fuel saving, but average per 100 km fuel saving about 30%.
2. can reduce the wearing and tearing to engine and transmission mechanism, prolong the use longevity of motorcycle.
3. the utility model is simple in structure, durable.
