Design and Development of Anti-Roll Back Mechanism

V. D. Kolate, R. R. Kurup, A. M. Latake

Abstract: The purpose of the paper is to analysis and reviews the already developed anti-roll back mechanisms for vehicles and other mechanisms of the same kind, to find the shortcomings of each of them, which hindered its general use in the vehicles, and to propose a mechanism overcoming all those shortcomings. Anti-roll Back Mechanisms or Unidirectional Motion Mechanisms are the mechanisms which may be added to the conventional gear box of a vehicle, to provide the remedy for the issue of descending of the vehicle under the influence of self-weight, faced while starting a vehicle to move uphill. Technically, this mechanism encounters the issue free motion of the shafts of the gearbox as the vehicle tries to roll downhill when the clutch is pressed (disengaged) for the moments in which driver shifts his foot from the brake pedal to accelerator pedal to accelerate the engine. Such mechanisms restrict one or the other shaft (s) of the gearbox to rotate opposite under the influence of wheels, thereby restricting vehicle to roll back in opposite direction. In this work the mechanism has been developed to stop the vehicle from rolling backwards when the vehicle is moving in the hill roads. Ratchet and Pawl mechanism has been identified to arrest the motion to the front axle. Anti-Roll Back mechanism has been fabricated and tested on the front axle assembly. The mechanism works well.

Keywords: Anti-roll back mechanism, unidirectional motion mechanisms, Ratchet and Pawl mechanism, etc
