摘要:
A vibration damping equipment for a torsional damper comprises a hub plate, side plates, a torsion spring, a friction block, and low rigidity members. Each low rigidity member is interposed between the hub plate and each friction block to be adjacent to each other through a partition of the hub plate. The low rigidity members are connected to each other on at least one axial side of the partition.

A torsional damper comprises damper elements which are resiliently coupled by a spring arrangement and a friction generating device. One of the damper elements has a radially extending wall. The friction generating device includes a plurality of friction blocks received by the other damper element with play in the circumferential direction, and a spring arranged to bias the plurality of friction blocks against the radially extending wall. In order to absorb the shock of engagement of each of the plurality of friction blocks with the other damper element, a cushion is provided.

A reconfigurable circuit has a plurality of calculation elements including a first calculation element and a second calculation element. The first calculation element has a first configuration memory for storing first configuration data. Output data of the first configuration memory is inputted to the second calculation element. A predetermined bit in the first configuration data is updated by using the second calculation element so as to modify the function of the first calculation element. The time required for testing the reconfigurable circuit is consequently reduced.

摘要:
Under control of rotation of a crankshaft 41, a friction roller 32 is pressed against a friction roller 31 in a radial direction, so as to achieve torque transmission between the rollers 31, 32. An inter-roller radial pressing reaction is canceled as an internal force in bearing supports 23, 25, with no input to a housing 11. The reaction causes a radial displacement of a bearing-fitting portion provided with inner and outer bearings 21, 42 in double layer arrangement, wherein the radial displacement is larger than that of a bearing-fitting portion provided with a bearing 18, 19, 22 in single arrangement, so as to cause unbalanced contact between rollers 31, 32. In order to prevent this, support stiffness of bearing support 23 against the inter-friction-roller radial pressing reaction is set higher than that of bearing support 25.
摘要:
A torque distributor includes a friction-drive mechanism having a first roller rotatable together with a first rotary member, partly constituting a torque-transmission path to primary drive wheels, and a second roller rotatable together with a second rotary member, partly constituting a torque-transmission path to secondary drive wheels. Also provided is an eccentric-crank mechanism for revolving the second roller in a direction opposite to a rotation direction of power transmission of the second roller around an eccentric-shaft axis displaced from a second-roller rotation axis to produce a displacement of the second roller from a non-power-transmission position of non-frictional-contact with the first roller to a radially-loaded power-transmission position of frictional-contact with the first roller. Although the friction-drive type is used, the torque distributor enables torque-distribution-control mode switching between them, while ensuring high-precision torque-distribution control by avoiding a polarity of moment acting on a rotational-position-control system for an eccentric crank from being reversed.

Under control of rotation of a crankshaft 41, a friction roller 32 is pressed against a friction roller 31 in a radial direction, so as to achieve torque transmission between the rollers 31, 32. An inter-roller radial pressing reaction is canceled as an internal force in bearing supports 23, 25, with no input to a housing 11. Each bearing support 23, 25 is formed with a constricted portion at a center section of the bearing support between bearing-fitting portions at end sections of the bearing support, for lowering support stiffness of the bearing support against the inter-roller radial pressing reaction.
