Anti Roll Back System

Abstract

An automobile is defined as a vehicle designed for operation on roads and usually has four wheels and a diesel or gasoline internal combustion engine. While driving on a hill road most of the drivers face the problem of rolling of a vehicle, it may be rolling backward or rolling forward which is termed as roll back system. The aim of the research is to arrest the motion of axle by using pawl and ratchet mechanism which will be operated electronically without utilizing the brakes. The objective of this is to design and fabricate a mechanism so that vehicle will not roll due to the slope of the hill and gravitational pull. The “Automobile Reverse Locking Differential Mechanism” is a preferred embodiment provides systems and methods for preventing a vehicle from reverse movement on a slope. This system consists of ratchet and pawl device connected to at least one wheel of the vehicle and actuator which will control the movement of the pawl while engaging or disengaging the mechanism where in the system may be engaged using an engaging mechanism when reverse motion is undesirable or to be restricted, and may be disengaged when the reverse motion is desirable. A push button will be provided on gear of the vehicle which will be operated by the driver on choice. In this work the mechanism will be developed to stop the vehicle from rolling backwards when the vehicle is moving on the hill roads.
