1. An electromechanically drivable brake pressure generator for a hydraulic braking system of a vehicle, comprising:
an electric motor, using which a driving rotational speed is generatable;
a planetary gear, which is driven on an input side of the planetary gear by the electric motor to render a gear ratio of the driving rotational speed to be slow, the planetary gear including an annulus gear, which is accommodated rotatably fixedly to the planetary gear in an annulus gear receptacle;
a hydraulic module, which is connected to an output side of the planetary gear and using which a brake pressure is generatable; and
at least one torque support situated between the annulus gear and the annulus gear receptacle, which extends in an axial direction between te the planetary gear and the annulus gear receptacle and which cooperates with a recess so that the annulus gear and the annulus gear receptacle are held rotatably fixedly with respect to one another;
wherein the electromechanically drivable brake pressure generator includes at least one of the following two features (I)-(II):
(I) annulus gear extends from a center of the annulus gear to a circumferential exterior edge of the annulus gear in a radial direction that is perpendicular to the axial direction in which the at least one torque support extends; and
(II) the at least one torque support is at least one of (i) pin-shaped, (ii) caulked at an axial outer side of the annulus gear receptacle, and (iii) made of a plastic material.
