Abstract
An arrangement for operating a brake of a vehicle has at least one controllable electric motor and at least one conversion device for converting the rotational movement of the electric motor into a translational movement of one or several brake element(s) operatively connected with the conversion device. The conversion device has two sloped disks which are arranged coaxially with respect to the electric motor, and whose first sloped disk can be caused to carry out a rotating movement by way of a step-down gear driven by the electric motor and whose second sloped disk, by way of roller bodies arranged between the two sloped disks, is axially displaceable by a rotating movement of the first sloped disk.

Arrangement for operating a brake of a vehicle, said arrangement comprising:
- a controllable electric motor, and
- a conversion device for converting the rotational movement of the electric motor into a translational movement of a brake element operatively connected with the conversion device,
- wherein the conversion device comprises two sloped disks which are arranged coaxially with respect to the electric motor, and whose first sloped disk can be caused to carry out a rotational movement by a step-down gear driven by the electric motor, and whose second sloped disk, by way of roller bearings which are arranged between the two sloped disks, is axially displaceable by means of a rotating movement of the first sloped disk.
A vehicle brake actuator assembly comprising:
- a housing,
- a brake element actuating piston supported for linear movement in the housing,
- an electric motor with a rotatably driven motor shaft, and
- a conversion device operable to convert rotational movement of the motor shaft to linear movement of the actuating piston,
- wherein said conversion device includes first and second sloped disks arranged coaxially with the motor shaft, said first disk being rotationally driven by said motor shaft and said second disk being axially driven by said first disk.
