Even though they are helpful, there are some sad events like accidents due to carelessness of rider, majority due to forgetting of lifting side stand. To rectify this problem many preventive measures have taken, but they consume extra power and also less in life. so as to eliminate this demerit and get effectiveness a new idea is taken as a project and it deals in this. This system is more effective and no separate power or effort consumption and easily be implemented practically in all types bikes. The new system AUTOMATIC SIDE- STAND RETRIEVE SYSTEM is designed based on the working principle of bikes. Since all bike transmit power from engine to rear wheel by means of chain drive. Since designed setup is kept in between chain drive, setup rotates and side stand get retrieves automatically. 1. Introduction Motorcycles are generally provided with stand for supporting the motorcycles when they are not in use. The stand usually comprises a bar or rod which is pivotally attached to the lower portion of the motorcycle frame and is movable to a literally, downward extending position so that the motorcycle can be tilted against and rest upon the bar. When the motorcycle is in use, the bar is swung upwardly and along the frame so that it will not interfere with the running of the motorcycle. Often the cyclist neglects to move the standard to its raised position and when a GENERAL IDEA:A small flat rod is attached and pivoted between the gear actuator lever and the side stand of the bike. When the gear is actuated the side stand gets lifted. Small stepper motor is connected between the side stand and the engine, when the engine is started the stepper motor runs and retrieves the sides stand automatically[5-9] CONSTRUCTION: The whole construction of this system is simple and efficient. The arrangement and position of components makes the system to function. Each and every component has its own property and responsibility. The power obtained from the chain drive is transmitted to the appropriate component without power loss. The systematic design of system is made in order to consume only very low amount of power initially for few seconds to retrieve the stand. Then the power consumption does not occurs after retrieving the stand. Construction of the proposed Automatic side stand retrieve system consists of four major components. They areaxle, Sprocket pinion, Lifting lever, Pushing lever. 2. Working of Components 1. AXLE A rod that serves to attach a wheel and provides support for bearings on which the wheel rotates. bike turn will make the stand strikes the ground and[1-4] causes the motorcycle to be thrown to the ground, generally with serious consequences to both the cyclist and the motorcycle.[1-4] 3. Sprocket Pinion Sprocket is the major component of this system because it is power transmitting device. It gets power from the chain drive and makes this system to work. It is the device which transmits the linear motion of meshing chain drive into rotary motion by means of the tooth found on it. The sprocket with ball bearings is said to be FREE WHEEL. Since it is a free wheel it allows the toothed part to rotate free from central portion in a direction. Hence this type of sprocket is used as the rear power transmission device in by cycle 357
that makes the wheel to rotate and also allows toothed area to rotate in anticlockwise when pedaled anticlockwise direction. This action of sprocket allows attached lifting lever to adjust freely automatically or manually when it does not engages with pushing lever properly. Since the sprocket transmit the power from chain drive, it should have the capability[13] to withstand the heavy loads of engine. So to withstand those impacts on toothed area, it is made of high carbon steel. The ball bearings are made up of high chromium steel. Hence all these material gives following properties for sprocket.[10-15] Heavy duty Smooth running Tempered Long life This smooth engagement leads proper Lifting Lever Lifting lever is the third major component of the system.the lifting lever is the rectangular rod made of MS-rod, which consists of two lifting leaves whichh is mounted with the edge of axle.[17] The lifting leaves should be parallel to the sprocket pinion. The lifting lever is composed of two metal rods, where both are welded at either sides of the axle. The free ends of the lifting leaves is tapered well. The ends are machined well for tapered shape for smooth engaging with pushing lever. be any degree. So due to effect of free wheel and tapered surface of the lifting lever can adjust itself.[16] 4. Push PSUSHING LEVER: Pushing lever is the component pivoted centrally to the side stand. The pushing lever is metallic rectangular plate, whose bottom end is bended in shape of C and top end is welded with a small piece of rectangular rod. This small piece of rod is used for getting lifted by the lifting lever. Since this rod engages (or) lays over tapered edge of lifting lever, thus the retrieving occur smoothly.the pushing lever is made of MS-flat rod with the length according to the distance of side stand arrangement. Its top end is made tapered so as to engage with lifting lever. The bottom end of the[18] lever is made as C-clamp, which holds the side stand These are four major components using in this system and other small components like Nuts and bolts, hooks etc. are used in this POWER SOURCE OF INCITER ASSEMBLY: Inciter assembly gets the power from the linear chain motion i.e. (as engine transmit power to the rear wheel through chain drive since the setup is When chain rotates anti-clockwise direction the inciter assemblies sprocket absorbs the power and rotates in clockwise direction[23]kept at the bottom and sprocket get engage with chain so,when chain rotates in anti-clockwise direction the sprocket engaged rotates in clockwise direction) as sprocket rotates the axle rotates as the result lifting lever rotates in clockwise direction.[24] POWER SOURCE OF RETRIEVER ASSEMBLY : As the retriever assembly s pushing lever get engage with lifting lever. It gets power from the rotation lifting lever and transmitss to the clamp and retrieve the side stand automatically. Rotary motion Linear motion Rotary motion retrieving of side-stand. This tapered surface makes the lifting lever as capable to withstand engine impact. When stand is moved vertical in position, the pushing lever engages with lifting leaves. This may not possible in all time, since the angle of lifting lever may Lifting Pushing Retrieving 358
WORKING PRINCIPLE: Sprocket side stand retrieve system retrieves the side stand automatically[26] if the rider forgets to lift the side stand while moving the bike. It works based on the working principle of the two-wheelers.every bikes transmit power from engine s pinion to the rear wheel i.e. rotary motion of the pinion makes the linear motion of the chain. That linear motion of the chain is absorbed by rear wheel s sprocket and converted into rotary motion. That rotary motion of the rear wheel makes the bikes to move. Based on this Sprocket side stand retrieve system is designed.[27] If Sprocket is kept between the chain drive, it make the sprocket to rotate so, using the sprocket as the major component this system works. It gains the power from the chain and make specially designed component (lifting lever) to rotate. This rotation incites engaged pushing lever to push the side stand to retrieve.the working of Sprocket-Side Stand Retrieve System is explained below in both (resting & riding condition of two-wheeler) 4.1. Resting Condition When two-wheeler is in resting condition i.e. when rider actuates the side stand of the vehicle to ground, the pushing lever that is pivoted at the center of the side stand gets engage with the inciter assemblies lifting lever. During this condition the inciter assembly [25]is at rest and retriever assembly (pushing lever s tapered end get engage with tapered end of lifting Lever) mounted with axle rotates. hence the lifting lever lifts engaged the pushing lever and therefore the pushing lever pushes the side stand by clamping it with the C shaped clamp stand holder and hence the spring tensed in the side stand get compressed quickly as a result side stand get retrieves[29] Figure 2.Riding condition The working of Sprocket-Side Stand Retrieve System is explained below in the flowchart Sprocket Meshing Down bottom Line of Chain Rightward Linear Motion Clockwise Rotation of Sprocket Lifting lever rotates Pushing lever pushes C-clamp forces Side Stand Retrieves Flow chart:-working position SIDE VIEW:. Figure 1. Resting condition Pushing lever s length can be changed according to type of bikes and distance calculated between the side stand and chain drive. Closed coil helical spring which gets pulled,the coil of spring get tensed during stand resting in ground.this is the condition of system during resting stage.[28] 4.2.Riding Condition When two-wheeler is started, Engine s pinion transmits power to the rear wheel by the chain drive. The inciter assembly which is kept at the center of the chain drive gets rotates as the sprocket gets engage with chain drive.so, when the sprocket rotates the lifting lever Figure 3.
