REDUCTION IN DEFLECTION OF THE OVERHANGING COMMON SHAFT OF TRACTORS

Abstract: One of the few problems/glitches found in modern day tractors is the deflections of the overhanging common shaft. This shaft is normally overhanging on one side due to the fact that it provides hinge mountings for both left and right brake pedals. Due to this overhanging cantilever setup, undesired deflections arise which could cause plastic (or permanent) deformation of the shaft, reducing pedal efficiency as well as increasing the amount of force required to actuate the brake mechanism. Other than this the overall packaging of the tractor is asymmetric which is also undesired. Asymmetric packaging means two different packaging sets have to be manufactured so as to package the tractor for safe transport. This paper discusses various solutions for solving the above mentioned problem.
