Abstract

The present invention provides an electronic braking system including an electromagnet housing in which an inner disc mounting end is integrally formed around an inner surface. The electromagnet is arranged inside the electromagnet housing. The motor plate is mounted at the motor / generator, and wherein an outer disc mounting end disposed outside the inner disc mounting end in a radial direction is integrally formed around one side surface. A disk unit is provided in which a plurality of inner disks and outer disks are overlapped between the inner disk mounting ends and the outer disk mounting ends to be combined with each other by friction generated by virtual pressure. A piston is provided according to the inner surface of the electromagnet housing, and the cover piston is connected with the plunger introduced along the support end of the rear cover, and is operated by the electromagnetic force of the electromagnet to supply virtual pressure to the disk unit.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2016-0144492 filed with the Korean Intellectual Property Office on November 1, 2016, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to electronic braking systems for transmissions.
