A clutch brake is provided that includes a brake housing adapted to be non-movably secured relative to a driveline master clutch. The brake housing includes a through-hole sized to allow passage of a shaft and at least one source of magnetic flux. The clutch brake also includes an armature secured for rotation with the shaft and positioned axially adjacent the brake housing in a disengaged state. At least a portion of the armature is adapted to move axially on the shaft in the presence of magnet...

The present invention relates to a brake piston with reduced transmission of heat from the disk to the brake fluid.In particular, the present invention relates to a disk-brake piston (7) characterized in that it comprises a cup (12) having a skirt (14) and a head portion (15), and a tubular insert (13) housed in the cup, a space for cooling air being defined between the outer surface of the tubular insert (13) and the inner surface of the skirt (14) of the cup (12).

The present invention relates to a hydrodynamic brake which comprises a stator, a rotor, a toroidal space defined by the stator and the rotor, a medium which is intended to be supplied to the toroidal space when the brake is activated, and a multiplicity of components for allowing regulation of the flow of the medium to and from the toroidal space. The hydrodynamic brake incorporates a structure with a multiplicity of recesses which each have an opening in a substantially common plane and each i...

An electromagnetic brake interposed between a fixed housing and a rotating member. The electromagnetic brake includes a multiplate brake mechanism, a ringlike core member fixed through an annular brake guide inside the fixed housing, an exciting coil accommodated in an annular groove formed on the core member, and a ringlike armature member arranged radially outside of the core member. Each of the core member and the armature member has a plurality of tapering surfaces. The tapering surfaces of ...

A brake device has at least one wheel cylinder operable by the pressure of a working liquid. A reservoir stores the working liquid discharged from the at least one wheel cylinder during the operation of an anti-lock braking function. A pump serves to transfer the working liquid from the reservoir. An outlet valve is disposed on the discharge side of the pump. A master cylinder receives the working liquid delivered from the pump via the outlet valve. A pulsation reducing device is disposed on a d...

A parking brake for a vehicle, including a parking brake unit, an actuating device situated inside the vehicle and operable to transmit an actuation signal to a control unit, a hydraulic circuit of a service brake of the vehicle connected to the parking brake unit, and an actuator and locking device for locking the parking brake in a braking position; the parking brake is actuatable by means of the hydraulic circuit and the actuator is a brake booster of the service brake.

A brake pad (34) has a rear surface (46) for support on an actuating member (32,64) of a disc brake and a braking surface (56) constituted by friction material (38). At least one hole (48) is arranged in the brake pad (34) at right angles with respect to the rear surface (46) to guide the brake pad (34) on a guide pin (60). A protective sleeve (54) for the guide pin (60) extends coaxially with the hole (48) in a direction towards the plane of the braking surface (56). The protective sleeve (54) ...

A brake cylinder for a hydraulic brake is constructed to have a resilient body between its piston and the brake fluid and to have a free space between the resilient body and the piston. The free space is free of hydraulic fluid and provides a space for the resilient body to occupy upon rise in the pressure of the brake fluid.

Brake disc for a vehicle disc brake, comprising a radially inner hub portion (1a) intended to be non-rotatably joined to a wheel hub and a surrounding, radially outer disc portion with oppositely facing friction surfaces. The outer disc portion is formed of two disc elements (4) joined to the hub portion, which are separated by spacers (7a 7d), which define passages for cooling air.

Brake disc for a vehicle disc brake, comprising a radially inner hub portion (1a), intended to be non-rotatably joined to a wheel hub, and a surrounding, radially outer disc portion with opposing friction surfaces. The outer disc portion is formed by two disc elements (4) joined to the hub portion, and which are separated by spacers (7a 7f), which define passages for cooling air and of which at least some (7a, 7b) are in the form of fan vanes to generate an airflow from the passage inlets (10) a...
