A brake assembly for an electric motor includes: a magnetic body, a winding, a bolt, a housing part with a brake surface, an armature disk, a brake pad plate, a shaft, a spring part, and a first bushing. The housing part is connected to the magnetic body by the bolt, with a positive fit in at least the circumferential direction. The first bushing is accommodated in a second bushing. The spring part supported on the housing part presses the first bushing and/or the second bushing toward the magnetic body. The radial clearance range covered by the armature disk includes the radial clearance range covered by the second bushing, and the axial region covered by the armature disk includes the axial region covered by the second bushing.

A brake mounting bracket mountable onto a trailing arm or a steering knuckle in a vehicle is provided. The bracket includes first, second, and third bracket mounting holes through which the bracket is configured to be mounted to the trailing arm or the steering knuckle of the vehicle. The bracket additionally includes first and second caliper mounting holes through which a brake caliper is configured to be mounted to the bracket. The first and second bracket mounting holes are separated by a first dimension that is less than a second dimension between the second and third bracket mounting holes. The first and second caliper mounting holes are separated by a third dimension matching a spacing between first and second mounting holes of the brake caliper. The third dimension is greater than both the first and second dimensions.

A brake caliper has an adjustment for controlling the location of the brake pads with respect to a brake rotor. The brake caliper includes a mount for attaching to a fixed surface to support the brake caliper, and a caliper connected to the mount for movement relative to the mount. A brake frame supports brake pads, one of which is movable with respect to the brake frame. An adjustor for controlling a position of the caliper with respect to the mount is configured for adjustment to change the position of the caliper with respect to the mount in an unactuated condition of the brake caliper thereby moving the caliper with respect to the mount and adjusting the position of the first and second brake pads with respect to the rotor. The brake caliper also may have an adjustable brake pressure feature.

The invention relates to a vehicle brake, in particular a utility vehicle disc brake, having a brake carrier with at least one brake pad holder, at least one brake pad which is guided so as to be axially displaceable and supported in the brake pad holder, and a brake caliper which is axially movable relative to the brake carrier.

According to the invention, it is proposed that the brake carrier is structurally reinforced on the run-out side relative to the run-in side, and at least one running direction indicator for indicating the first rotational direction is arranged on the brake carrier.

A truck axle may include a disc brake having a brake caliper and brake pads for application onto the brake disc. The brake caliper has a first interior space with an opening on the side facing the brake disc for receiving an application device, and the brake caliper has a second interior space for receiving the brake disc. The truck axle with the disc brake is optimized with respect to cost and installation space, wherein the disc brake can easily be mounted on a truck axle. A brake caliper includes bolt guides, and a wheel carrier includes guide bolts that receive the bolt guides thereon. An axial space is defined within a bolt guide hole between a base of the bolt guide hole and the end of the guide bolts disposed within the bolt guide hole. The guide bolts may be integral with or separately connected to the wheel carrier.

A friction pad mounted on a disk brake includes a back plate, and a lining attached to the back plate and configured to frictionally contact a disk. A spring member, configured to bias the friction pad toward a disk rotationally exiting side, is provided to an ear portion of the back plate. The spring member includes an attachment portion attached to the back plate, an extension portion extending from an end portion of the attachment portion, and an abutment portion folded back from the extension portion and extending in a direction toward the disk. The abutment portion is configured to receive a reaction force from a torque reception surface by abutting against the torque reception surface at a position on an opposite side of the ear portion from the disk when the ear portion and the torque reception surface of a mount member abut against each other.

A tie bolt is disclosed. In various embodiments, the tie bolt includes a shank having a first end and a second end; and a counterbore disposed at the second end of the shank, opposite the first end, the counterbore having a counterbore depth and a counterbore diameter.

An adapter body is configured to be attached to a vehicle body in each of a first orientation in which a caliper body is coupled to the vehicle body via the adapter body in a first position corresponding to a first disc brake rotor having a first outer diameter, and a second orientation in which the caliper body is coupled to the vehicle body via the adapter body in a second position corresponding to a second disc brake rotor having a second outer diameter different from the first outer diameter. The indicator is configured to indicate an correspondence between an orientation of the adapter body and at least one of the first disc brake rotor and the second disc brake rotor.

A bracket for a brake assembly and a brake actuator includes a unitary body including a tube configured to receive a camshaft of the brake assembly and an actuator mounting arm disposed proximate a first end of the tube and configured to receive the brake actuator. In some embodiments, the tube includes one or more helical ribs formed on a radially inner surface. The bracket further includes either a brake spider or a brake spider mounting flange disposed proximate a second end of the tube. In either embodiment, material may be omitted in various locations to reduce the weight of the bracket. The bracket may be formed through an additive manufacturing process and in a manner that achieve at least one of a predetermined torsional stiffness and attenuation of a predetermined natural frequency.

The rotor of an electric motor unit has a web portion partially enclosing the remainder of the unit and terminating in a circumferentially extending rim. The brake drum defines an engagement surface for drum brake linings, and has an outboard end defining a flange securable to the wheel hub. The brake drum also includes an open inboard end, partly covered over by a dust guard, and a circumferential wall extending between the outboard and inboard ends and surrounding the engagement surface. By way of keys and slots or recesses, a reinforcing ring interlocks the circumferentially extending rim of the web portion and the circumferential brake drum wall. The reinforcing ring is secured to the circumferentially extending rim and to the wall of the brake drum at a location disposed axially between the rim of the web portion and the brake drum lining engagement surface.
