Abstract
An apparatus for transmission of torque between the crankshaft of an engine and the input shaft of a variable-speed transmission in a motor vehicle has a primary flywheel with a membrane which is connectable to the crankshaft, a secondary flywheel which is connectable to the input shaft by way of a friction clutch, a damper with circumferentially acting coil springs in an annular chamber of the first flywheel radially outwardly of the membrane, and torque transmitting arms which are carried by the second flywheel and alternate with the coil springs of the damper. A slip clutch can be installed between the torque transmitting arms and the second flywheel to limit the magnitude of transmittable torque.
Claims21
Apparatus for transmitting torque in a motor vehicle, comprising a first flywheel rotatable about a predetermined axis and including a membrane having a first portion adjacent said axis and connectable with a rotary output element of an engine in the vehicle, said first flywheel further including a toroidal portion defining an annular chamber spaced apart from and surrounding said axis, said membrane further having a second portion surrounding said first portion and connected with said toroidal portion;
- a second flywheel coaxial with and rotatable relative to said first flywheel and connectable with an input element of a transmission in the vehicle by a clutch;
- at least one antifriction bearing between said flywheels;
- and at least one damper operative to oppose rotation of said flywheels relative to each other and having energy storing elements installed in said chamber and acting in the circumferential direction of said flywheels.
