TH89584B - Hydraulic modulator for brake device - Google Patents

Abstract

To provide a hydraulic modulator for the brake device which can be made to be smaller By improving the arrangement of components and the internal structure even better The narrative, as disclosed here, is a hydraulic modulator 60 that includes 64 cylinders for the support of 35 power pistons to be moved and for change. The volume of the hydraulic chamber 65, which connects to the brake caliper 80, follows the displacement of the power piston 35 and the electric motor 63 for sliding the 35 power piston through the power transmission trajectory 64 extends to the spindle 73 and The rotary motion of the 63 electric motor will be converted. It is a linear motion on an axis parallel to the axis 73. The power transmission path will be It is provided with a ball screw mechanism consisting of a 77 ball screw nut, 78 ball screw and 79 ball screw rod for converting the 63 electric motor rotational motion to linear motion of the slider for thrust 68. The pusher for pushing 68 has a head 68a, which moves into a spherical contact with the 35 power piston.
