Literature Review Abstract – In the transmission system chain drive is considered as the most robust and efficient mode of power transmission because of its highest transmission efficiency. Transmission system mostly consist of Chain and sprocket combination with 2 sprockets which maintains the TR of 3 which is basically required to propel the vehicle i.e. to overcome the frictional resistance WRT to road[2]. The changes were made such, within the given CD between the sprockets we can achieve the TR above 3 or even above 4 by using the concept of compounding. Using the compounding in the chain is possible but using it in 2wheeled vehicle is difficult because of the constant cyclic fluctuations and polygonal effect[3]. First trial was taken in ATV vehicle like Quad bike which has space as well as CD constrains. After the use of the compounding arrangement, it shows the drastic improvement in GR and SR with which we have increased the efficiency as well as speed of the vehicle.1st trial was used in Quad bike which is basically All-Terrain Vehicle which basically used in heavy Terrain. Key Words: Gear ratio(GR), compounding, Fictional resistance,

Niels Fuglede And Jon Juel Thomson[1] (Kinematics and Dynamic Modelling and Approximate Analysis of Roller Chain Drive), in this research paper they told about the best method for transmitting the power in vehicle. Roller chain drives are applied for power transmission in many mechanical systems due to high energy efficiency, large power capacities, timing capabilities, flexibility in choosing shaft centre distance and ease of installation and maintenance. The undesirable noise and vibrations present in the roller chain drive is the ongoing study for use of the chain drive. C. Pereira, J. Ambrosis and A. Ramalho[2] (Dynamics of Chain Drive Using Generalised Revolute Clearance Joint Formulation), in this research paper they told about the roller chain drive and the positive power transmitting capacity of the roller chain and sprocket. Due to the positive power transmitting capacity of the chain it is mostly selected for transmission of power. In this research paper they also told about the dynamic behaviour of the roller chain and manufacturing of the roller chain.

1. INTRODUCTION
S. Mahalingam[5] (Polygonal Action of The Chain Drive), in this research paper they told us about what the polygonal effect is exactly and why it must be considered during the manufacturing or selection of the chain and sprocket. The detailed calculation about the polygonal effect is shown in this research paper.
All-Terrain Vehicle (ATV) is the one which is capable to clear all the terrains like muddy-hills-off read tracks. For this, an ATV always required and robust drive train system which can work under several conditions as well as in fatigue loading. Mostly in all the ATV’s, chain drive is used for transmitting the power because of its advantages over other drive. Chain drive is mostly preferred because it is easy to adjust the speed ratio and the gear ratio as per the requirement and it is simple in maintenance. Compound drive is the one of the innovations that being used in our ATV. By using the compound arrangement, we can modify the gear ratio and speed ratio within the minimum center distance and achieve the maximum torque and speed than the rated one. Basic requirement of TR is 3 in order to propel vehicle by overcoming the FR offered by road. We can achieve above 4 by changing the pair of sprockets that being used.

Yong Wand, Desheng Ji and Kai Zhan[3] (Modified Sprocket Tooth Profile of Roller Chain Drive), in this research paper they told us about polygonal action and meshing impact form the non-conjugated mashing features damages the tooth profile. This research paper is based on the developing the new tooth profile with reduced polygonal effect and meshing impact under high speed.
