  • Patent number: 12292757
    Abstract: A magnetorheological braking device with a fixed holder and a first and second braking component. One of the braking components is connected to the holder and does not rotate relative thereto. The two braking components are continuously rotatable relative to one another. The first braking component extends axially, and the second braking component has a hollow shell part extending around the first braking component. A peripheral gap, filled with a magnetorheological medium, is formed between the first and second braking component. The first braking component has an electric coil and a magnetically conductive core extending axially. Magnetic field concentrators, on the core and/or the shell part, protrude into the gap, creating variable gap height. The electric coil is wound around a section of the core.

  • Patent number: 12257986
    Abstract: When a leak occurs in one service circuit of a multi-circuit braking system, the leak can prevent replenishing the non-leaking service reservoir. To address this problem, a shared backup reservoir can be used to replenish the non-leaking service reservoir. A valve can be used to allow flow from the backup reservoir to whichever service reservoir is under higher pressure, as low pressure would indicate a leak. Additional valve(s) can be used to impede flow from the service reservoirs to the backup reservoir to prevent the service reservoirs from being drained if the backup reservoir is subject to a leak.
