Brake equipment for holding and braking an elevator car in an elevator installation, which is arranged to be movable along a brake track in two directions of travel, includes a mount with a brake lining which automatically adjusts under friction couple with the brake track on movement of the elevator car relative to the rail and in that case tightens a first tightening means, which can be released by an actuator. The first tightening means tightens the mount together with the brake lining against the brake track by a biasing force. The brake equipment produces, with unmoved brake equipment and an unreleased state of the actuator, a holding force acting in both directions of travel. The holding force is determined substantially by the biasing force acting on the mount.

An elevator installation has braking equipment for braking and holding an elevator car which moves in vertical direction within guide tracks or rails. The braking equipment consists of at least two brake units each comprising a normal force regulation device that sets a normal force (F_N) in correspondence with a normal force value determined by a brake control unit and/or a locking device that locks the brake unit in a set braking position and which preferably maintains the set braking position in the case of an interrupted energy supply. The braking equipment provides a gentle braking or holding of the elevator car, which corresponds with the operational state of the elevator installation, with a low energy requirement.

PCT No. PCT/GB96/02888 Sec. 371 Date Jun. 5, 1998 Sec. 102(e) Date Jun. 5, 1998 PCT Filed Nov. 22, 1996 PCT Pub. No. WO97/19843 PCT Pub. Date Jun. 5, 1997An electronic braking system for trailers. A control system is incorporated into the braking equipment of a towing vehicle to provide a trailer braking command signal. This signal is regulated so as to balance the braking between the towing vehicle and the trailer through the assessment of forces in the coupling between the two vehicles. The assessment is made indirectly and is calculated from forces measured in the suspension components of at least two axles of the towing vehicle and the changes occurring therein during braking.

The present invention provides a method and a system for controlling a braking equipment of a motor vehicle in order to activate the braking equipment at a standstill of the motor vehicle such that braking forces are built up which are necessary to keep the motor vehicle in a state of standstill. To this end it is established on the basis of vehicle movements whether the vehicle is at a standstill. If vehicle movements are detected that cannot occur during driving modes of the motor vehicle, the motor vehicle is in a state of standstill. Subsequently, the braking equipment, and in particular a holding brake mechanism included in the braking equipment, are activated. In order to provide braking forces keeping the motor vehicle at a standstill also when it is on a slope, the braking equipment, and in particular the holding brake mechanism, are controlled in response of the vehicle inclination present in the state of standstill.

A hydraulic control valve for an Anti-lock Braking System (ABS) includes a modulator block having at least a housing, an inlet port, a receiving unit, and an outlet port. The housing is coupled to at least a plunger, an armature, and a coil body. The housing also has a coupling hole to receive a valve seat. Upon application of a current, a coil generates a magnetic field causing a plunger coupled with the armature to perform a reciprocating motion in which a projection of the plunger moves in contact with and separates from an aperture in the valve seat to adjust fluid flow. The hydraulic control valve also comprises fluid flow paths, provided in a space between the valve seat and the housing, which communicate with an outlet port. The hydraulic control valve accommodates at least a filter and a seal cup on the outer periphery of the valve seat.

The present invention relates to a method and a device for controlling braking equipment of a motor vehicle. Here, an operating state of a motor vehicle is determined, in which the motor vehicle is to be brought from a state, in which its speed is not zero, into a state, in which the vehicle no longer moves. If such a transition from a traveling state into a state of standstill is determined, braking equipment of the motor vehicle is controlled such that braking forces are produced, which are capable of bringing the motor vehicle into the state of standstill and/or assisting a vehicle driver in doing this. It is also possible to produce braking forces in the state of standstill, which are capable of holding the motor vehicle in the state of standstill. The present invention additionally enables to assist a vehicle driver when starting a motor vehicle. In this case, an operating state of the motor vehicle is detected in which the motor vehicle is to be brought from a state of standstill into a traveling state. If such an operating state is present, the braking equipment of the motor vehicle is controlled such that the braking forces produced by the braking equipment in the state of standstill are reduced in such a way as to allow a transition into the traveling state and/or to assist the vehicle driver in this respect.

The present invention provides start-up assistance for a motor vehicle having braking equipment which, in the stationary state of the mo-or vehicle, automatically or under the control of a vehicle driver summons up braking forces needed for the stationary state. To assist start-up of the motor vehicle through a reduction of the braking forces generated in the stationary state, a start-up request of a vehicle driver is determined when defined conditions, which are to be met for start-up of the motor vehicle, exist in the stationary state. Once a start-up request has been recognized, the operating state of the motor vehicle is checked until an operating state required for start-up exists. Once such an operating state is reached, the braking equipment of the motor vehicle is controlled in such a way that its braking forces generated in the stationary state are reduced to allow start-up of the vehicle.

By calculating the energy used by the friction brake equipment, the amount of friction brake shoe/pad wear can be monitored. As the amount of energy supplied reaches a percentage of the friction brake shoe/pad energy design limit, an indication for inspection is provided. If the supplied friction energy continues to increase beyond this point, the brake material must be replaced. The software logic limits are tunable for custom configuring by the transit authority and maintenance personnel. This invention measures the amount of friction effort supplied with respect to time and distance in a software controlled brake system. Furthermore, this invention allows the software to determine when the friction brake material must be replaced based on actual data, which simplifies the maintenance personnel operation procedures, maximizes brake material wear, and avoids costly damage from braking with worn out shoes/pads. The material life remaining for friction brakes is determined currently by a visual inspection followed by a 'best guess' as to whether the material will last until the next scheduled inspection. This invention will annunciate through the software logic program when the friction material requires inspection and replacement. Additionally, the invention provides software logic to indicate the remaining material thickness.
