#CMT# #/CMT# The device has an electric motor (1), and a mechanical actuating unit for actuating a mobile element e.g. brake cable, to be actuated along a translation movement in two opposite directions. The mechanical unit has a reducer mechanism located at an output of the motor and formed by an endless screw (19) and a toothed sector (16). A movement transforming mechanism is formed by a connecting rod (5) and semi cranks. The transmission mechanism transforms a rotational movement, from the motor, in an output of the reducer mechanism to a translational movement applied to the mobile element. #CMT#USE : #/CMT# Mechanical device e.g. electric parking brake (claimed), for transforming rotational movement to a translational movement that is applied to a brake cable in a motor vehicle. #CMT#ADVANTAGE : #/CMT# The reducer mechanism offers mechanical efficiency of 60 percentages. The movement transforming mechanism offers mechanical efficiency of 90 percentages. The device transforms the rotational movement to the translational movement with high efficiency in the order of 50 percentages. The device improves comfort and safety. The device is robust, reliable and economic, and utilizes less power and inexpensive actuator. The device is simple in design and is easy to assemble and fabricate. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial schematic front sectional view of a movement transforming device. 1 : Electric motor 5 : Connecting rod 15 : Semi-cranks 16 : Toothed sector 19 : Endless screw. |
