  • Publication number: 20240093739
    Abstract: A brake disc configured to be connected to a vehicle axle and to be squeezed between brake pads, comprising a central disc body (30) having a first and a second side (32, 34), wherein the second side faces in the opposite direction compared to the first side; a first and a second disc plate (36, 38), each disc plate having a wear surface for producing friction when a brake pad is pressed against the wear surface. The disc plates are releasably secured to said first side and second sides, respectively, so as to enable the first and second disc plates to be replaced by other disc plates. A connecting member (64) prevents rotation of the disc plates relative to the central disc body, the connecting member extending from the first disc plate, through a passage (58) in the central disc body, to the second disc plate. Also presented is a vehicle comprising such a brake disc.

  • Publication number: 20230141095
    Abstract: A brake disc configured to be connected to a vehicle axle and to be squeezed between brake pads, comprising a central disc body (30), first and second disc plates (36, 38) releasably securable to the central disc body. Each disc plate has a wear surface and a disc body facing surface. The brake disc has a geometrical centre axis. Each disc plate has an inner periphery and an outer periphery extending from the wear surface to the disc body facing surface. A first ledge (60) mates with the inner periphery of the first disc plate, and a second ledge (60) mates with the inner periphery of the second disc plate. Each ledge comprises at least a ledge portion which is inclined relative to the geometrical centre axis for counteracting axial movement of the disc plates relative to the central disc body.

  • Publication number: 20230108312
    Abstract: A brake pad retainer system in a vehicle disc brake comprises a calliper bridge and a calliper housing supporting brake pads on either side of a rotary brake disc, wherein the system is arranged to hold one brake pad in position relative to the calliper bridge. The retainer system comprises a retainer bracket arranged parallel to the brake disc axis and extending across a back plate of the brake pad, and a retaining spring arranged along a radially outer portion of the back plate and extending between the retainer bracket and the back plate. The retainer bracket has an angled surface arranged in contact with a corresponding first angled surface on the retaining spring. The retaining spring has a second angled surface arranged in contact with a corresponding angled surface on the radially outer portion of the back plate. The disclosure also relates to a brake pad.

  • Publication number: 20230048379
    Abstract: The invention relates to a wheel end assembly for a vehicle, comprising a central wheel support member such as a spindle or a steering knuckle, and an outboard wheel end bearing arranged concentrically around the central wheel support member. The outboard wheel end bearing comprises roller elements accommodated between an inner race-forming part and an outer race-forming part surrounding the inner race-forming part. The inner race-forming part is configured to be supported by the central wheel support member. The central wheel support member comprises a first rotational lock portion. The inner race-forming part comprises a second rotational lock portion configured to engage with the first rotational lock portion to prevent the inner race-forming part from rotating relative to the central wheel support member. The invention also relates to a vehicle comprising such a wheel end assembly.

  • Publication number: 20230050021
    Abstract: A vehicle wheel end assembly comprising a wheel hub, rotatably mounted on a wheel axle spindle by a wheel bearing s comprising a roller bearing. The wheel bearing has a bearing inner ring mounted on an external section of the wheel axle spindle and a bearing outer ring mounted in an internal section of the wheel hub. The assembly further comprises a threaded hub nut mounted at the end of the wheel axle spindle to fix the bearing inner ring on the wheel axle spindle and a rotational lock mechanism to prevent relative rotation between the bearing inner ring and the wheel axle spindle. The rotational lock mechanism comprises a tangential surface arranged to intersect a part of an inner circumference of the bearing inner ring at right angles to the axis of rotation in a plane located at or adjacent an outer radial end surface of the bearing inner ring.

  • Publication number: 20220402482
    Abstract: A control unit arranged to monitor a load distribution of a vehicle when the vehicle is in motion, the control unit comprising an interface arranged to receive a plurality of load values associated with one or more vehicle axles and/or one or more vehicle wheels from a plurality of load sensors arranged on the vehicle, wherein the control unit is arranged to determine a vehicle load distribution based on the plurality of load values, to compare the determined vehicle load distribution to a pre-determined allowable vehicle load distribution, and to trigger an emergency procedure in case the determined vehicle load distribution differs from the pre-determined vehicle load distribution by more than an allowable amount.

  • Publication number: 20220290727
    Abstract: A brake pad retainer arrangement for holding a brake pad in position relative to a disc in a disc brake. The arrangement comprises an elongated retainer bracket arranged to extend transversely over the disc and the brake pad, wherein the retainer bracket is spring loaded to press against a rim portion of the brake pad. The retainer bracket is also arranged to engage the rim portion at an angle, thereby biasing the brake pad in a direction away from the disc.
