Title:
ELECTRIC BRAKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/054491
Kind Code:
A1
Abstract:
This electric braking device (10) comprises a linear motion conversion mechanism (16) having a screw shaft (29) caused to rotate by an electric motor (15), and a nut (30) that moves linearly in accordance with the rotation of the screw shaft (29). The electric braking device (10) generates braking force in a vehicle wheel (13) due to a piston (19) connected to the nut (30) moving linearly within a cylinder (18) and applying pressure to brake fluid. In such an electric braking device (10), a coil spring (31), of which the extending/retracting direction is the linear motion direction of the piston (19), is installed in such a state as to be sandwiched between the piston (19) and the screw shaft (29), so as to be compressed in accordance with the linear movement of the screw shaft (29) in a direction for reducing braking force and to generate repulsive force against the compression.
