Industrial Technologies Development of Principally New Pneumatic Vibroprotective Systems
Development of Principally New Pneumatic Vibroprotective Systems
Description
Pneumatic vibroprotective module for the seat suspension of various purpose transport means drivers (tractors, trolleybuses, lorries etc.), which allows to reduce vibrations perceived by a driver 3 times in comparison with the best world sam-ples.
Innovative Aspect and Main Advantages
According to the results of dynamic tests of a trolleybus, tractor and bus with the driver seats with pneumatic vibroprotective module, the maximal eigenfrequency of the seat vibrations is not higher then 1.0 Hz, and the maximal amplifying factor at the resonance frequency is not higher then 1.2, which is sufficiently lower then the permissible values.
Areas of Application
Different transport means like cars and lorries, buses, agricultural machinery, locomotives and helicopters.

Stage of Development
Experimental samples of autonomous vibropro-tective pneumatic modules are used in driver seat designs by Cherkassy bus enterprise at the as-sembly of city buses of “Bogdan” type, by pro-duction enterprise “Yuzhny machinebuilding plant” at production of YuMZ-6AKM type trac-tors, by “UkrAvtoZapchast” company at the as-sembly of “Belarus” tractors in Ukraine, by “UkrAgroSelMash” company at production of “Yarilo” tractors.
