VIBRATION AND NOISE PREVENTIVE CONSTRUCTION FOR AGRICULTURAL TRACTOR

摘要

PURPOSE:To prevent noises from a transmission case and/or oil pressure case from being amplified by the fender or step, by interposing vibration preventive rubber between the vibration/noise preventive cover and the transmission case and/or oil pressure case and thereby supporting them in the condition of being afloat to each other. CONSTITUTION:The right and lfet fenders 7L, 7R, the right and left steps 6L, 6R and the right and left wind-shield covers 5L, 5R are all connected with a fender connecting cover 16 and a step connecting cover to form a solid vibration/noise preventive cover A as in a single piece. Vibration preventive rubber is borne at points 11L, 11R, 13R of fenders situated below the sheet 4 plus two points 10L, 10R of a step connecting plate 12. This is not however sifficient because the steps 6L, 6R will be bent by the weight of operator. Thus Vibration preventive rubbers 21L, 21R are interposed inside the wind-shield plates 5L, 5R to provide coupling with the side cover of dash board.
