HYDRAULIC SUPPORT OF AUTOMOBILE ENGINE UNIT SUSPENSION Russian patent published in 1999 - IPC

FIELD: transport engineering; engine unit hydraulic supports. SUBSTANCE: proposed hydraulic support has hollow housing formed by lower and upper attachment units inseparably interconnected by elastic material (rubber) wall. Rigid partition divides housing space into two hydraulic chambers, working and compensating ones, communicating through ring throttling channel made axially inside partition. Gas compensator is arranged in central part of partition. Partition has central hole whose side wall is provided with blind axial slot in which vibrating diaphragm made of elastic material (rubber) is fitted with guaranteed clearance. Height of slot exceeds thickness of diaphragm wall in place of its fitting in slot. Diaphragm is convex in shafe forming central sealed gas space (gas compensator) inside. EFFECT: improved dynamic characteristics of hydraulic support over entire operating frequency-amplitude fluctuation range, improved smoothness of running and comfort of vehicle. 2 cl, 2 dwg
