  • Patent number: 10766470
    Abstract: This brake control device includes: an operation amount sensor which detects the brake operating member operation amount; front-wheel and rear-wheel actuators which generate braking force in front/rear wheels; front-wheel and rear-wheel sensors which detect the outputs of the front-wheel and rear-wheel actuators; and a controller which controls the front-wheel and rear-wheel actuators based on the operation amount and the outputs of the front and rear wheels. On the basis of the operation amount and/or the output of the rear wheels, the controller determines whether or not a long-term low-load state in which the friction member is continuously pressed against the rotary members of the rear wheels within a predetermined range over a long period of time is established. If so, the distribution ratio of the rear-wheel braking force to the total applied braking force is decreased compared to when a long-term low-load state is not determined to be established.

  • Patent number: 10759404
    Abstract: An actuation system, in particular for a vehicle brake, may include an actuating device, such as a brake pedal, at least one first pressure source, e.g., a piston-cylinder unit (master cylinder), which can be actuated in particular by means of the actuating device and a second pressure source, in particular a piston-cylinder unit, with an electro-mechanical drive. The pressure sources may each be connected to at least one brake circuit via a hydraulic line, in order to supply the brake circuit with pressurising medium and to pressurise the vehicle brake. There may further be a valve device for regulating the brake pressure. It is planned that during forward and return stroke at least one brake circuit can be fed controlled pressurising medium by way of the second pressure source.

  • Patent number: 10704635
    Abstract: A spring assembly is provided which decreases the fatigue and wear on the springs of the assembly. The spring assembly includes upper and lower pistons separated by a substantially incompressible fluid. The lower piston is attached to one or more springs. The surface area of the upper surface of the lower piston is greater than the surface area of the lower surface of the upper piston. As such, the springs are deflected by a distance less than the distance traveled by the upper piston. By decreasing the length the springs are compressed, the springs are subject to less fatigue and wear. As a result, the life span of the springs is increased and the maintenance required of the spring assembly is minimized relative to that of typical spring assemblies.
