Title: Four-wheel drive vehicle
Inventor: HAGA KYOSUKE
IPC: F16D43/284
Filed: 1990-05-22
Abstract: PURPOSE:To eliminate a tight corner braking phenomenon by arranging a driving force transmission device whose forward/backward input characteristics are different between a rotation distributing device installed on a power transmission shaft and a driven wheel. CONSTITUTION:When an input/output shafts 17, 18 rotate relatively and a rotating member 41 rotates relatively in a housing 30, high viscosity fluid 44 with which a pressure chamber 43 is filled is forcibly moved by a blade 42. At this time, inner pressure which is proportional to a relatively rotational speed difference in a rotating member 41 is basically generated in the pressure chamber 43 by both the wall surfaces of the end surface of an end cover 31 and the end surface of a piston 34, and a viscosity friction action to the inner periphery of the housing 30. A difference is generated in the behavior of the high viscosity fluid 44 by the rotational direction of the blade 42 to the housing 30. Namely, by the selection of the shape of the blade 42, the pressures generated in the pressure chamber 43 at the time of forward torque transmission and backward torque transmission are different from each other, and at the time of backward torque, the degree of pressure generation becomes lower.
