Abstract

In today s scenario, rear axle with differential lock arrangement is one of the key required parameter for military vehicles. As per the current central motor vehicles rules an all wheel drive army vehicle can be considered as an off-road vehicle if the vehicle at least has an arrangement of differential lock at its rear axle. This paper details the development of such rear axle with differential lock and validation of the design in-line with the durability test on heavy duty chassis dynamometer. A comparison of recommended design standards and test results is also presented.

Abstract

This paper details the design and validation of an improved cable-type accelerator control system for left hand drive (LHD) army vehicles. A slider mechanism is used for the pedal control unit. The design is verified by kinematic analysis using ADAMS simulation. The vehicle performance and verification of ergonomic parameters are tested using a prototype vehicle. Improvements in the ergonomics, system reliability and packaging/installation in comparison with the existing accelerator control system are demonstrated.

Keywords
