Abstract
The utility model discloses an automatic clutch type driven sprocket of a motor cycle, which comprises a gear tooth and a mounting hole 7. The utility model is characterized in that a sprocket 2 of an outer ring is used as a driving member; a star wheel 1 is used as an overdrive clutch which is composed of a driven member; the gear tooth is formed on the outer circle of the sprocket 2 of an outer; the mounting hole 7 is formed on the star wheel body. Compared with the prior art, the utility model has the advantages that the damage of a gearbox caused by the inertial impact of a motor bicycle body is avoided, the service life of an engine is prolonged, the utility model is favorable for maintaining a motor bicycle body, and oil-bearing material is saved, etc.
Description
The utility model relates to motor bike driven sprocket manufacturing technology field, exactly is a kind of motor bike driven sprocket that has the automatic clutch function.
The power drive system of gear change motor bike mainly is made up of driving engine, change speed gear box, drive sprocket, chain, driven sprocket.Wherein, driving and driven sprocket wheel is the member of one-piece construction; Drive sprocket connects with output shaft of gear-box, and driven sprocket connects with the wheel hub of motor cycle rear wheel (hereinafter to be referred as trailing wheel) by mounting hole on it; Engine output power reaches trailing wheel by change-speed box, drive sprocket, chain, driven sprocket, and trailing wheel and driven sprocket are rotated synchronously, advances thereby drive motor bike.Use the subject matter of the driven sprocket existence of this version to be: when operating motor bike gearshift is slowed down or received the oil deceleration, car body inertia power will directly act on change speed gear box and driving engine, make driving engine by towing astern, thereby produce following problem: 1. when above-mentioned deceleration-operation is relatively more unexpected, very easy appearance makes change speed gear box damage because of the force of inertia impact of car body, and accelerates the rate of wear of driving engine main parts size.Simultaneously, make car body be difficult to keep balance, be easy to cause traffic accident.2. when motor bike band shelves moved, coasting distance was short, thereby has correspondingly improved consumption of fuel.
The purpose of this utility model is for people provide a kind of when motorcycle shift slows down or receives the oil deceleration, can make driving engine not by the motor bike driven sprocket of towing astern
The purpose of this utility model is achieved in that it comprises the gear teeth and mounting hole 7, is characterized in, this sprocket wheel is that loop chain wheel 2 is the overriding clutch that driven member is formed for driving member, with star-wheel 1 beyond one; Make the described gear teeth on the cylindrical of this outer shroud sprocket wheel 2, be shaped on described mounting hole 7 on this star-wheel body.
Above-mentioned overriding clutch is the roller friction clutch, and it constitutes like this: make the annular groove that cross sectional shape is a rectangle on described outer shroud sprocket wheel 2 bore areas; On the excircle of described star-wheel 1, make several wedge shape mouths, in the star-wheel body of a surperficial side, make vexed hole at each wedge shape bore; Compression spring 9 is housed in the vexed hole, and the push rod 4 that is slidingly installed; On described each wedge shape mouth two sides, fixedly install plate washer 6, make it to form webge slot, roller 3 is installed between each webge slot and described annular groove.
After the utility model is realized,, connect by roller wedging locking between outer shroud sprocket wheel and the star-wheel, and the drive trailing wheel rotates synchronously when the rotating speed of outer shroud sprocket wheel during greater than star wheel rotate speed; When outer shroud chain wheel speed was lower than star wheel rotate speed, sprocket wheel connected with locking between the star-wheel and is unlocked, and makes both rolling touch.Like this, operating motor bike is when shift down or the deceleration of receipts oil, the force of inertia of car body just can not directly act on change-speed box and the driving engine by driven sprocket, driving engine also just can not because of above-mentioned this deceleration-operation by towing astern, thereby the utility model is compared with prior art had the following advantages: 1. can avoid change-speed box to impact fully and damage because of car body inertia.2. in above-mentioned moderating process, can make driving engine keep tickover, thereby reduce the degree of wear and the operating temperature thereof of its main parts size, and then help prolonging the service life of driving engine.3. in motor bike runs slowly process, help keeping car body to operate steadily, drive comfortable.4. motor bike band retaining coasting distance greatly increases, thereby helps saving fuel oil.
Below in conjunction with accompanying drawing embodiment of the present utility model is done explanation in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the section-drawing of outer shroud sprocket wheel A-A.
As seen from the figure, the utility model mainly is by star-wheel 1, outer shroud sprocket wheel 2, roller 3, push rod 4, backing plate 5, plate washer 6, compression spring 9 is formed, star-wheel 1 is the ring body member made from steel material, make 4 wedge shape mouths on its cylindrical in uniform way, each wedge shape mouth is made of radial surface and bottom surface respectively, in the star-wheel body of a surperficial side, respectively make a vexed hole at each wedge shape bore, and in its bottom surface one side star-wheel body, respectively make a dovetail furrow along its gauge direction, also on the star-wheel body, also be shaped on 4 mounting holes 7, this mounting hole is as the connection holes between star-wheel and the motor blockchain rear-wheel hub, and the version in this each hole is same as the prior art; Outer shroud sprocket wheel 2 is with the ring body member that steel material is made, outer shape is the ladder bar shape, is shaped on the gear teeth on its excircle, and the manufacturing technology of these gear teeth is same as the prior art, is shaped on the cannelure that section form is a rectangle on its bore area; Roller 3 is cylindrical shape steel parts, and the width dimensions of its length dimension and above-mentioned cannelure is complementary, both free-running fits; Push rod 4 is axis body members of taking the lead, and each vexed bore dia of making on its axis body outside diameter and the star-wheel is complementary both bearing fits; Backing plate 5 is that the cross sectional shape that steel material is made is trapezoidal cylinder member, and the dovetail furrow size of making on its underpart cross-sectional shape size and the star-wheel body is complementary, both transition fit, and the length dimension of backing plate equals the star-wheel gauge; Baffle plate 6 is quadrntnt members of making by figure with steel material.Above-mentioned each part all passes through different heat treatment in manufacturing process, so that improve its intensity, hardness, resistance to abrasion, make it to adapt to use needs separately.
After above-mentioned each part is made, get final product by the figure assembling.Wherein each plate washer 6 lays respectively at each position, both sides, wedge shape mouth bottom surface, and by connector 8, promptly double-screw bolt, nut, packing ring are fixedly linked on the star-wheel body.Thereby make each wedge shape mouth place form webge slot.
In the present embodiment, backing plate 5, like this has been installed in the star-wheel body of each wedge shape mouth bottom surface one side, when its upper surface and the serious abrasion of roller mating surfaces, has been convenient to change.Certainly, this backing plate 5 is not set.And directly being contacted with that make and wedge shape mouth that do not have dovetail furrow bottom surface on the star-wheel body, roller also is fine.
As from the foregoing, loop chain wheel 2 was driving member beyond the utility model came down to one, was the overriding clutch that driven member is formed with star-wheel 1.
As everyone knows, as overriding clutch, its version promptly can be the roller friction-type clutch structure that provides in the present embodiment, also can be spin friction-type clutch structure or click formula clutch structure.
