FLUID JOINT
Document Type and Number:
Japanese Patent JPS63186041
Kind Code:
A
Abstract:
In order to insulate sound from vibrations or oscillations of an internal-combustion engine from being transmitted through solid bodies to a connected drive element, a hydrodynamic transmission (3) is used which has a resilient bearing means (10) for a secondary shaft (9) within the transmission. The bearing means (10) is provided with an annular hollow or solid insert (15) made of resilient material. However, no part associated with the secondary side has metallic contact with the primary side of the transmission. In this manner, not only is the torque transmitted solely by of the working fluid of the transmission with simultaneous attenuation of rotary oscillations, but sound emission from a crank-shaft (1) into the transmission (3) is totally suppressed. The means (10) includes a self-aligning roller bearing within a sleeve (11) between which and a projection (14) of the transmission housing the insert (15) is located. The primary rotor (5) is connected to the crankshaft (1) and defines two bladed cavities (6) cooperating with the bladed cavities (7) of a secondary rotor (8). The rotor (8) is connected to the secondary or output shaft (9). Adjustable gaseous pressure may be applied within the insert (15).
