20090020374 | Buggy Cart Brake System - A grocery cart braking system is described having a brake release bail bar assembly, a clutch disk assembly, a replaceable sacrificial brake shoe, and a biased brake rod assembly. The clutch disk assembly may be a single disk or a two part disk assembly. The two part disk assembly allows adjustment of the bail bar relative to the biased brake rod assembly. Mechanical advantage may be achieved with the clutch disk assembly allowing greater or lesser braking force for the same actuation force of the bail bar. Braking bias force may be adjusted by positional adjustment of the spring cage or the spring retaining means. The braking system may be applied to one or more cart wheels, preferably two wheels. | 01-22-2009 |

The brake system also includes a spring assembly, a fluid chamber defined by the bore and the piston, and a hydraulic fluid supply network. The spring assembly provides a biasing force to maintain the piston in an actuated position engaging a stator which engages the rotor of a vehicle. The hydraulic fluid supply network provides pressurized fluid to the fluid chamber to selectively overcome the biasing force of the spring assembly and move the piston to an unactuated position to release the rotor. Thus, the caliper brake is spring actuated and hydraulically released. | 01-29-2009 |
20090032342 | Electric disk brake - An object of the present invention is to, in an electric disk brake, prevent uneven abrasion of a disk rotor due to contact of the disk rotor to a brake pad when brake is not in operation. In the present invention, a rotation of an electric motor is slowed down by a differential speed reducing mechanism, and is converted to a linear motion of a piston by a ball ramp mechanism. Brake pads are pressed against a disk rotor by the piston to generate a brake force. When brake is not in operation, the piton is retracted by a reverse rotation of the electric motor so that a predetermined pad clearance is maintained. When brake is not in operation, a pad-retracting-control electric current is supplied to the electric motor so that the piston is biased backward while being maintained in one position. When brake is not in operation, contact of the disk rotor to the brake pads due to runout of the disk rotor triggers smooth retracting of the piston, whereby uneven abrasion of the disk rotor can be prevented. | 02-05-2009 |
