Abstract
A brake device for producing a braking force by pressing a friction member against a member to be braked in response to a deformation produced by applying a DC voltage to a piezoelectric element array including a stack of piezoelectric elements. A plurality of piezoelectic element arrays are coupled by a displacement transmission mechanism such that deformations produced by the piezoelectric element arrays are added together.
Claims6
A brake device including a piezoelectric element array havng a stack of a plurality of piezoelectric elements which act to press a friction member against a member to be braked, under the action of a deformation of said piezoelectric element aray caused by applying DC voltage thereto, thereby producing a braking force,
- said brake device comprising a plurality of piezoelectric element arrays which are arranged in a parallel relationship with each other and are connected together by a displacement transmitting mechanism so that the deformations of the respective piezoelectric element arrays are added together to produce the braking force.
