摘要： A torsional damper type flywheel device includes drive side and driven side flywheels, a first spring mechanism connecting the drive side and driven side flywheels, a second spring mechanism which may include an air cushion spring, and a viscous damping mechanism arranged in series with the second spring mechanism. The series combination of the second spring mechanism and the viscous damping mechanism is arranged parallel to the first spring mechanism and connects the drive side and driven side flywheels. This flywheel device continuously changes its vibrational bahavior between two characteristics due to the action of the viscous damping mechanism. Due to the vibrational behavior change, no notable resonance occurs when the rotational speed passes through the resonance speed of the flywheel device. A continuously sliding friction mechanism is not used.

摘要： Amplitude of transmission error of tooth pair of a gear is obtained in relation to actual contact ratio (.epsilon..sub.r) which is an angular range (.theta..sub.r) of actual contact of the surfaces of the tooth pair divided by an angular pitch (.theta..sub.p) of the gear. The specifications and/or tooth surface modification of the gear is/are are determined so as to reduce the transmission error amplitude under non-load condition in which the actual contact ratio (.epsilon..sub.r) is 1.0. Alternatively, the specifications and/or tooth surface modifications is/are determined so as to increase an effective contact ratio (.epsilon..sub.n) which is an angular range (.theta..sub.n) divided by the angular pitch (.theta..sub.p), the angular range (.theta..sub.n) corresponding to a portion of a path of the tooth contact point in which an edge contact of the tooth pair does not take place at the tooth top or at the ends of the face width of the teeth. These arrangements permit efficient and easy designing of a gear having a reduced noise, without simulations or tests.

摘要： A torsional damper type flywheel device wherein at least one of flywheel device components, for example, a spring connecting a drive side and a drive side of the flywheel device is asymmetric with respect to an axis of rotation of the flywheel device to form a total, original imbalance with respect to the axis of rotation. The flywheel device includes a compensating imbalance which is equal and opposite to the original imbalance as a vector and is equally divided into two portions each distributed to each of the drive side and the driven side. The compensating imbalance is formed in the drive side and the driven side before assembly of the flywheel device. When the drive side and driven side rotate relative to each other by a torsional angle .theta. and thus a gravity center of the asymmetrically arranged spring rotates by an angle .theta./2 about the axis of rotation, a vector defined by the two portions of the compensating imbalance also rotates by the angle .theta./2 about the axis of rotation. As a result, the flywheel device is maintained in balance at all torsional angles.

摘要： A flywheel device including driving and driven side flywheels, a first spring mechanism directly connecting the two flywheels with a predetermined torsional angular gap, and a second spring mechanism provided in parallel to the first spring mechanism and connecting the two flywheels via a friction mechanism provided in series with the second spring mechanism. The flywheel device has two vibrational characteristics between which the flywheel device changes its vibrational behavior while passing through the resonance speed to suppress amplification in vibration. The friction mechanism slips momentarily only while passing through the resonance speed and does not slip at a standard range of engine speeds. Due to the lack of slippage of the friction mechanism at the standard range of engine speeds, the torque variation absorbing effect of the flywheel device is greatly improved.

摘要： A hybrid drive system comprising: a torque amplify mechanism coupled to an output member of an internal combustion engine and an output member of an electric motor, as energized by an electric power to output a torque, for amplifying and outputting the torque, as outputted from the internal combustion engine, by controlling the torque of the electric motor; and a continuously variable transmission arranged between torque amplify mechanism and the output shaft for increasing/decreasing and outputting the torque inputted from the torque amplify mechanism. Further comprised is a forward/backward switching mechanism between the torque amplify mechanism and the output shaft for setting a forward state, in which the inputted motive power is unreversed and outputted, and a backward state in which the inputted motive power is reversed and outputted. As a result, the reverse run can be made only with the motive power outputted from the internal combustion engine.
