The slidable holder has a curved guiding groove defined therein for receiving the brake base. Two anti-lock inclined surfaces are positioned between the curved guiding portion and the curved guiding groove. Each anti-lock surface has a shallow section and a deeper section. Two wheel sets are disposed between the curved guiding portion and the curved guiding groove. A seat member connected to the slidable holder and receives an elastomer.

| 20110272230 | BRAKING APPARATUS FOR VEHICLE - An electronic control unit inputs from temperature sensors a temperature of the heating side of a thermoelectric conversion section assembled to each of brake units provided for left and right rear wheels. When the temperature of the heating side is equal to or lower than a predetermined temperature, the electronic control unit drives and controls a brake hydraulic pressure control section so as to operate the brake units preferentially over brake units provided for left and right front wheels. With this operation, each of the brake units generates friction heat, and heats the heating side of the corresponding thermoelectric conversion section, whereby the thermoelectric conversion section efficiently collects thermal energy and generates electrical power. Meanwhile, when the heating side temperature is higher than the predetermined temperature, the electronic control unit drives and controls the brake hydraulic pressure control section so as to decrease the proportion of the braking forces applied by the brake units and increase the proportion of the braking forces applied by the brake units. | 11-10-2011 |
| 20120073922 | Method for controlling a brake system of a motor vehicle and a brake system for a motor vehicle - A brake system for a motor vehicle and a related method includes a hydraulic service brake system, having a brake booster and is operable via a brake operating element, an electric machine, operable as a generator to brake the motor vehicle, and an electromechanical braking device. A setpoint braking torque is determined as a function of a brake pedal travel. The hydraulic service brake system has an idle travel between the brake operating element and a master brake cylinder, in which no braking torque is generated by the vehicle brake system. In the range of the idle travel, the setpoint braking torque is generated by the generator and/or the electromechanical braking device, and a portion of the electromechanical braking device in the setpoint braking torque is modulated as a function of a portion of the generator in the setpoint braking torque so that variations of the generator portion are compensated. | 03-29-2012 |
