Abstract

An energy storing brake for a vehicle, such as an industrial truck, includes a rotating brake rotor (5) and a non-rotating braking body (3) that can be moved relative to the brake rotor (5). The braking body (3) can be pressed by an energy storing device (4), preferably realized in the form of a spring, against the brake rotor (5), and can be detached from the brake rotor (5) by a brake lifter against the force of the energy storing mechanism (4). A hydraulic cylinder (8) can be pressurized as required, by which a supplemental force in the same direction as the force of the energy storing mechanism (4) can be exerted on the braking body (3). The hydraulic cylinder (8) can be pressurized as a function of the actuation of a brake control mechanism, preferably of a brake pedal, by an operator. The sum of the forces that can be exerted on the braking body (3) by the energy storing mechanism (4) and by the hydraulic cylinder (8) is quantitatively greater than the force that can be exerted on the braking body (3) by the brake lifter.
