A drum brake, in particular for a utility vehicle, has a brake drum, which is rotatably mounted about a rotational axis, and multiple brake shoes, which are mounted in a receiving area of the brake drum and each of which has a friction lining support and a friction lining arranged thereon. The brake shoes can be pressed against a brake drum casing inner surface, which is designed as a friction surface, in a radial direction relative to a rotational axis of the brake drum. The interior of the drum brake is equipped with a brake cylinder assembly which is rotationally fixed to an armature housing for actuating the brake shoes. A respective pressing wedge is arranged on the friction lining support face facing away from the friction lining. The pressing wedge lies on a wedge mechanism which can be moved in a parallel manner relative to the rotational axis of the brake drum. The wedge mechanism can be moved from a non-braking position into a braking position by moving the service brake piston of the brake cylinder assembly in a parallel manner relative to the rotational axis of the brake drum.

A brake unit for utility vehicles includes a carrier unit and a transmission element. The carrier unit has a guide section in which the transmission element can be arranged such that the transmission element can be moved along a guide axis. The transmission element includes a first receiving section, which can be engaged with a piston rod of a brake cylinder, and a second receiving section, which can be engaged with a tappet of a wedge unit. The transmission element is configured to transfer forces and transfers along the guide axis between the piston rod and the tappet.

Disclosed herein is a single shoe-type brake apparatus. The single shoe-type brake apparatus includes: an integrated sideways U-shaped single brake shoe configured to form an open ring shape, to be integrated into a single body, and to have a separation region on one side thereof so that it is subjected to external force in a direction where it is extended to both sides thereof; a cylinder installed in the separation region, and configured to provide the external force; and a friction material coupled to the outer circumferential surface of the brake shoe, and installed to selectively come into contact with a brake drum as the brake shoe is extended. The friction coefficient of the friction material is considerably lower than that of a common brake friction material, and a brake factor is almost identical to that of a brake apparatus having two shoes.

A hydrostatic rotary machine includes (i) an inner element and an outer element which are coaxial and mounted with the ability to rotate one with respect to the other about an axis of rotation, one of these elements being a rotor and the other of these elements being a stator, (ii) a brake counter-disc which is mounted on the distribution hub, which extends radially around the distribution hub, and which is rotationally coupled to the outer element, (iii) a passive-braking piston designed to activate a brake under the effect of an elastic element and which is mounted with axial mobility with respect to the brake counter-disc, and (iv) a hydraulic brake-release chamber positioned between the brake counter-disc and the passive-braking piston.

A gearbox assembly including a gear assembly, an input shaft, an output shaft, and a gear brake system. The input shaft is coupled to the gear assembly. The output shaft is drivingly coupled to the input shaft through the gear assembly. The gear brake system is disposed within the gear assembly, and includes one or more brake devices. The gear brake system actuates the one or more brake devices to brake the gear assembly during a reverse torque condition of the gearbox assembly.
