20090057075 | BALL-IN-RAMP BRAKE CALIPER TYPE PARKING BRAKE FOR VEHICLE - In a BIR type brake caliper according to the embodiment of the present invention, when a BIR (Ball in Ramp) type cartridge assembly, which generates an axial force while rotating, presses pads against a disk plate during parking braking, balls provided between input and output ramps of the cartridge assembly move along variable trajectories gradually decreased in a radial direction and increase a force. For this reason, even though an operation force of a parking lever is small, the cartridge assembly generates a force capable of maintaining a parking braking force. As a result, it is possible to obtain characteristic reducing an operation force, which should be applied to a parking handle by a driver. | 03-05-2009 |
20090321195 | DISK BRAKE - A pneumatic disc brake for utility vehicles has two brake pad carrier plates to which brake pads are fixed. The disc brake is equipped with an application device which has two pressure plungers. By way of a force-absorbing connection between the pressure plungers and the facing surface of the brake pad carrier plate, a bridge is relieved of bending stresses. The end faces of the pressure plungers and at least the contact faces of the facing brake pad carrier plate are provided with profilings, which engage into one another in a form-fitting manner, such that at least in the event of full-load braking, each brake pad is moved in the peripheral direction. | 12-31-2009 |
20100012442 | HYSTERESIS CHARACTERIZING TYPED ELECTRO PEDAL DEVICE - According to the electro pedal of the present invention, a pedal simulator is achieved by a variable damper including a piston operating with an operation rod connected to a pedal and elastically supported by first and second springs having different elasticity, a piston flange having a flow channel, through which the oil passes, at the end of piston elastically supported by second spring in a chamber filled with the oil, and a rubber cup being in close contact with piston flange and changing the flow rate of oil while being elastically deformed by the hydraulic pressure according to the flow direction of the oil, such that hysteresis characteristics showing pedal effort without difference can be achieved, such as when hydraulic pressure is used, not only generating simple linear pedal effort and a damping force from a fixed damping coefficient in operation and return stroke of pedal. | 01-21-2010 |
20120018261 | FIXING STRUCTURE OF AUXILIARY BRAKING DEVICE FOR UTILITY VEHICLE - A fixing structure of an auxiliary braking device for a utility vehicle is provided, which includes a brake disc mounted on a driving shaft at which an output of a transmission is received; a brake pad mounted at a vehicle body in such a manner as to compress the brake disc by the cooperative operation with the manipulation of a brake lever mounted at a driver seat and to perform a braking operation; and a spline coupling part mounted at one end of the driving shaft in such a manner as to be fixedly coupled to a rear axle input shaft of a rear wheel differential gear so as to have the restriction in the axial movement thereof. | 01-26-2012 |
20120037464 | DISK BRAKE FOR A RAILWAY VEHICLE HAVING AN ELECTRICALLY INSULATED BRAKE LINING RETAINER - A disk brake for a railway vehicle is provided. The disk brake includes a brake disk, a brake caliper encompassing the brake disk, the brake caliper pressing a brake lining disposed on a brake lining retainer against the brake disk in case of actuation via a brake lever. The brake lever and the brake lining retainer are connected to each other by a hinged connection, wherein the brake lever and the brake lining retainer are electrically insulated from each other. | 02-16-2012 |
20120312644 | BALL RAMP CALIPER BRAKE - A caliper brake including a housing and a rotating actuator received in a bore in the housing, the rotating actuator having a head positioned within the housing and an outer tapered surface located outside the housing. A lever includes a bore with an inner tapered surface that mates with the outer tapered surface of the rotating actuator. A threaded nut is received over a threaded end portion of the rotating actuate and applies pressure to the lever to rotationally secure it to the rotating actuator. An inner stator is positioned adjacent to the head of the rotating actuator and an outer stator is spaced from the inner stator, the stators being axially movable. A plurality of ramped depressions are provided in both the head and in a backing plate of the inner stator, and a ball is positioned between each of the ramped depressions. | 12-13-2012 |
20130175123 | SYSTEM AND METHOD FOR OPERATING A BRAKE LEVER - A system for operating a brake lever includes a handle and a lock having a first position that prevents pivotal movement of the handle with respect to the lever and a second position that allows pivotal movement of the handle with respect to the lever. A method for operating a brake lever includes locking a handle to the lever to prevent pivotal movement between the handle and the lever and manually positioning the lever to apply and release the brake. The method further includes unlocking the handle from the lever to permit pivotal movement between the handle and the lever and automatically positioning the lever to apply the brake. | 07-11-2013 |
20150021126 | CALIPER BRAKE DEVICE FOR RAILWAY VEHICLES - A caliper body is slidably attached to a truck in the axial direction of a wheel. The body has a tip end portion branched off into two parts. One part is close to an outside of one side of the wheel with another part close to an outside of the other side of the wheel. An operating lever is arranged that rotates, via a protruding-retreating motion of a pneumatic actuator rod, one end side via a connecting link around an eccentric axis, which is rotatably supported by one of branched-off parts of the caliper body, as a center. One brake shoe is slidably installed to an anchor pin of the caliper body to freely rotate on a tip side inner surface of a caliper lever installed in an eccentric part. Another brake shoe is installed on a tip side inner surface of the other branched-off part of the caliper body. | 01-22-2015 |

20150353107 | RAILWAY VEHICLE DISC BRAKE APPARATUS - Provided is a railway vehicle disc brake apparatus that is capable of ensuring sufficient strength to withstand a reaction force from a disc, and that can be reduced in weight. A caliper lever of the railway vehicle disc brake apparatus has a pair of working point side arms, and a working point section. The working point section links the pair of working point side arms, and holds a pad via a working point shaft. The pair of working point side arms are inclined in such a manner that the interval therebetween narrows as the working point side arms approach the working point section. Furthermore, each working point side arm is inclined with respect to a reference plane that is perpendicular to the direction in which the working point section extends. | 12-10-2015 |
