Title:
ACTUATOR FOR FRICTION ENGAGING DEVICE
Document Type and Number:
Japanese Patent JPS63203958
Kind Code:
A
Abstract:

PURPOSE: To reduce the size of a device to a relatively low value and to enable fine and rapid execution of response, by providing a torque generating mechanism, converting electric energy to torque, and a torque-thrust force converting mechanism, converting torque of a screw mechanism, a cam mechanism, etc., into a thrust force with the increase in a force.

CONSTITUTION: When, based on signals from sensors, detecting a throttle opening, a running speed, etc., a proper electric signal is outputted from a control part, according to the signals, electric energy is converted into torque by means of a torque generating mechanism. The torque is converted into a thrust force by means of a torque-thrust force converting mechanism, and further, the thrust force causes engagement or disengagement of a friction engaging device through a friction engaging press mechanism. In this case, through location of a torque increasing mechanism between the torque generating mechanism and the torque- thrust force converting mechanism, a thrust force is produced. Namely, the engaging force of the friction engaging device can be controlled directly by means of electricity, control is facilitated, and response is improved.
