Title:
CONSTANT SPEED TRAVELING DEVICE
Document Type and Number:
Japanese Patent JPS63151540
Kind Code:
A
Abstract:
PURPOSE:To improve the accuracy in constant speed traveling with gain control corresponding to a vehicle type by comparing actual vehicle speed with set one to generate a control signal for controlling a drive motor and an actuator. CONSTITUTION:When current is supplied to an electromagnetic coil 17, a magnetic flux is generated and a magnetic fluid 14 is transformed into cylindrical one. Thus, a container 13 is also transformed cylindrically so that a variable rhombus lever 7 is expanded between elbows 6, 6 through a connecting rod 16 and contracted between elbows 4, 5. By controlling exciting current to said coil 17 is adjusted the degree of transforming the magnetic fluid 14 from spheric 1 to cylindrical configuration so that the pivotal radius of the variable rhombus lever 7 is controlled and the stroke of a transmitting wire 26 can be controlled.
