Abstract

An add-on brake system (1) for clamping a wheel disc a vehicle includes a housing (10) accommodating a direct-drive linear actuator, which includes: an electric motor constituted by a rotor (70) and a stator (80); a nut arrangement (73) fixedly and directly coupled to the rotor (70) and configured for revolving therewith; a linear threaded plunger (20) associated with the nut arrangement (73) for being driven thereby in a linear direction upon the revolution of the latter, the plunger (20) having a first end linearly protruding from one end of the nut arrangement (73) and a second end linearly protruding from an opposite end of the nut arrangement (73). The system also includes: at least one inboard brake pad (50) fixedly coupled to the housing; at least one outboard brake pad (60) associated with the second end of the linear threaded plunger (20), oriented transverse to the linear threaded plunger (20) and configured for being driven thereby in the linear direction. The linear threaded plunger (20) has an initial unclamped position in which the second end protrudes to a first extent n 1 from the other end of the nut arrangement, yielding a first spacing S 1 between the inboard and outboard brake pads (50, 60), and a final clamped position in which the second end protrudes to a second extent n 2 > n 1 from the other end of the nut arrangement (73), yielding a second spacing S 2 < S 1 between the inboard and outboard brake pads (50, 60), allowing clamping the wheel disc.
