Abstract

Currently, various tractors are available with clutch pedal linkage mechanism. Majority of the linkages are manually operated with no power assistance. However, some tractor manufacturing companies do have other type of clutch pedals with operate hydraulically or electrically. Clutch pedal operation force is usually cumbersome. Therefore, there is a need to have linkage mechanism which reduced pedal force.

LOW EFFORT CLUTCH PEDAL USING DOUBLE REDUCTION MECHANISM

INTRODUCTION

Currently, various tractors are available with clutch pedal linkage mechanism. Majority of the linkages are manually operated with no power assistance. However, some tractor manufacturing companies do have other type of clutch pedals with operate hydraulically or electrically. Clutch pedal operation force is usually cumbersome. Therefore, there is a need to have linkage mechanism which reduced pedal force.

PROPOSED SOLUTION

Construction

In the proposed concept there is set of linkages interconnected such a way for given pedal travel clutch can be activated with lower pedal force. Both primary and secondary linkages can be adjusted as per the requirement of the operator.

How this concept works?

In the proposed concept, linkage is operated by foot, thereby interconnected linkages gets activated and thus pedal effort gets transferred to clutch operation lever. Based upon simple lever machine principle, pedal effort can be reduced by increasing pedal travel and vice versa.

Double Reduction Linkage Mechanism


1) Most of the times linkages are with single pivot position, with single reduction. Here, single reduction means one can adjust the force multiplication only once. However, in the proposed concept there is arrangement which has double pivot. With this arrangement, one can get pedal effort multiplication twice as that of single reduction.


2) One can have different combinations of p...
