Improvement in Gear Shift Performance of Manual Transmission System

Nilesh A. Phalke | Dr. V. Singh

Abstract: Fast growth in the Indian economy has steered to new market trends for commercial vehicles. In todays aggressive automobile market, customer expectations are very high, particularly in respect of comfort and quality. Gear shifting is vital interface between driver and vehicle, any inconsistency in gearshift performance can give rise to customer unsatisfaction results into negative impression of brand image. Although every vehicle manufacturer is striving to improve gearshift performance Double Bump continued to be stress area in shift feel. The main objective of this work is to improve gearshift performance of North-South (N-S) transmission with help of variable parameters namely cable routing optimization, introduction of gear shift linkage inertia mass and introduction of shifter shaft detent profile. It also aims at finding correlation among variable parameters with help of Gear Shift Quality Assessment (GSQA) trough experimental analysis. This work consist of a number of tasks such as modelling of component, CAD simulation and series of GSQA test with the help of Ricardo software and hardware.
