A centrifugally triggered brake mechanism is used to halt a rotating assembly. The brake mechanism includes a braking surface, a brake shoe, and a rotating centrifugal trigger. Upon attaining a selected rotational speed the trigger releases the brake pad to engage the drum. The mechanism may be useful for instance in providing backup overspeed protection for wind turbines.

A brake drum includes an outer drum, at least one layer of heat resistant adhesive, provided at least on the inner radial surface of the outer drum, and an inner drum provided inside the outer drum connected with the outer drum via the at least one adhesive layer.

Provided in a device for activating a wheel brake of a vehicle, having a tensioning installation which has a spindle drive, are two electric motors, the first electric motor by way of a first gear mechanism acting bi-directionally on the spindle drive. In order for the position of the tensioning installation, once attained, to be fixed in a parking brake, a second electric motor by way of a second gear mechanism, which has a self-locking worm gear mechanism and by way of at least one releasable coupling that acts uni-directionally in the activating direction, is coupled to the spindle drive. The coupling is composed of a cam on an output shaft of the first gear mechanism, and a pin on an output element of the worm gear mechanism. Since the cam cannot be reversed beyond the pin, a latching position of the tensioning installation is defined in this way.

A drive braking unit, including a wheel hub motor and drum brake. The drum brake includes a brake drum and a braking unit in the brake drum. The drive braking unit includes a base plate to which a drive stator is fastened. The braking unit is arranged on a first side of the base plate. The braking unit is designed for mechanical connection to a vehicle's interface, which is arranged on a second side, situated opposite the first side, of the base plate. This provides a drive braking unit with an improved integration of wheel hub motor and drum brake. Between at least one component of the drum brake and an opening running through the base plate, there is arranged at least one sealing element for sealing off the first side from the second side. Thus, the drive braking unit is sealed off against water penetration and brake dust escape.
