  • Publication number: 20190084538
    Abstract: A braking system with function of anti-somersault, comprising: a hydraulic unit, a piston, a drive unit, a suspension travel sensor, and an ECU. During braking, according to a suspension travel signal generated by the suspension travel sensor, the ECU is able to determine whether a vehicle with short wheel base and high centre of gravity tends to be subject to forward somersault or not. Once confirmed, the ECU immediately sends a control signal to the drive unit, so as to drive the piston move towards a pressure releasing direction, such that fluid pressure on the downstream side of the hydraulic unit is blocked from changing. Moreover, further increase of the piston's displacement increases fluid volume in an oil chamber of the hydraulic unit so as to largely reduce the downstream fluid pressure. Consequently, braking force applied to the vehicle by the braking caliper decreases, and the forward somersault is prevented.

  • Patent number: 8479890
    Abstract: An actuating assembly, including a rotatable core and an electric drive for driving the rotatable core are disclosed. The rotatable core is arranged for engagement with a cable disposed within a pair of conduit sections and the cable can connect with a pair of actuatable devices. The rotatable core is arranged to be operable to pull the cable on each side of the core upon rotation thereof in a first direction, and to extend the cable on each side of the core upon rotation thereof in a second direction. The assembly further includes a pair of reaction abutments disposed on opposite sides of the rotatable core and to which a respective end of each conduit section can be connected. The assembly is arranged to be fixedly mounted and the reaction abutments are mounted for movement relative to the rotatable core for equalisation of cable load transmitted through the conduit sections.
