The fluid enclosure increases the force of the actuator such that smaller, more controllable actuators may be used to control the brake.

Abstract: A method for adjusting or altering the play between brake linings and friction surfaces of motor vehicle brakes by means of controllable and adjustable lifting and return movements of the brake linings is disclosed. In this case, the play is altered as a function of the actuation of the gas pedal, such that the play is reduced if the pressure exerted on the gas pedal is reduced and/or if the gas pedal is released.

Abstract: A motor is secured to a housing by securing bolts. These bolts are threaded into screw-threaded holes formed in the housing so as to be parallel to an axis of rotation of a motor driven shaft, which drives radially reciprocal plungers that are disposed in diametrically opposed pump bores located on either side of the shaft. The screw-threaded holes are arranged close to, but offset from, the pump bores so that extrapolations of the screw-threaded holes do not intersect the pump bores or cavities in which pressure pulsation dampers or reservoirs are defined, enabling the housing to be small and low in vibration and noise.

Abstract: A fluid sealed type vibration insulating device provided with an actuator for generating an active supporting force. The vibration insulating support device includes a main fluid chamber defined by a conical-shaped elastic support and a movable construction part. The movable construction part is constituted by a partition wall and a magnetic path member which is fastened to the partition wall through a clearance spacer. Therefore, a clearance is formed between the partition wall and the magnetic path and a plate spring is installed in the clearance to support the movable plate against the magnetic force of a permanent magnet. The partition wall has an internal thread hole to be bolted. The magnetic path has a hole with one opening diameter larger than another opening diameter for inserting a bolt. The bolt has a dish-shaped bolt head. If a center of the hole is off to the side of the center of the partition wall's hole, any edge point of the bolt head contacts any surface of the inner hole and pushes.

Abstract: A spring-actuated electromagnetic brake includes a noise-suppressing device for suppressing a striking noise emitted when an armature is attracted onto a field to release the brake when an electromagnetic coil is excited to magnetize the field. The noise-suppressing device is comprised of a plurality of hemispherical elastic members each disposed in one of recesses formed in one of two opposed surfaces of the field and the armature. When the brake is in the engaged state, a hemispherical surface of each elastic member partially projects from the recess and is in contact with the other of the two opposed surface. When subjected to a compressive force or pressure applied from the armature, the hemispherical elastic member undergoes elastic deformation as a whole and does not produce any locally concentrated elastic deformation. The hemispherical elastic member is highly durable and is able to greatly suppress the striking noise generated when the brake is released.

Abstract: An electronic brake controller for controlling electric brakes of a towed vehicle, such as a trailer, wherein the controller includes a resistive braking force sensor that senses the braking force applied by the driver of the towing vehicle to the brake pedal and provides an electrical signal proportional to the braking force to an electronic control unit. The electronic control unit is operable when a microprocessor thereof detects the brake light “on” condition and the presence of the force sensor. The microprocessor receives the signal from the braking force sensor and controls braking force applied to the trailer brakes in proportion to the force applied by the driver of the towing vehicle to the brake pedal. During operation, the microprocessor reads ambient temperature compensated electrical conductance of the braking force sensor to provide a temperature compensated output signal proportional to the braking force to actuate the trailer electric brakes.

Abstract: The invention relates to a braking device (10) having a spindle gear (18, 20) for actuating a friction brake (14, 16), a gear drive (30, 36) for driving the spindle gear (18, 20) and having an electric motor (40) for driving the gear drive (30, 36). For safety reasons, the invention proposes a second electric return motor (34) for releasing the friction brake (14, 16). Particularly when the two electric motors (34, 40) are connected to mutually independent power supplies, this has the advantage that the friction brake (14, 16), if one of the two electric motors (34, 40) or one of the two power supplies fails, can be released with the other electric motor (40, 34).

Abstract: The air damper includes a housing with cylindrical walls and a piston assembly reciprocating therein. The piston assembly includes an interior surface against which a seal abuts. The interior surface is textured in a grained pattern so that interstices are formed between the seal and the interior surface thereby forming an effective air passageway for damping. A cylindrical spacer spaces the interior surface from a retainer and the seal is engaged around the cylindrical spacer and between the retainer and the interior surface. An alternative embodiment inserts textile material through a damping orifice in order to vary the rate of damping.

Abstract: A gas spring with a first gas chamber communicated with a second gas chamber through a calibrated orifice to control the rate of return of gas from the first chamber to the second chamber to thereby control the rate at which a piston rod of the cylinder returns to its extended position. Desirably, the rate of return of the piston rod to its extended position can be made slow enough to prevent damage to a die stamped part as the gas spring lifts the part from a lower die half. The gas spring composite shell is preferably formed of and contains materials which are highly thermally conductive and define the return passage to prevent the gas spring from becoming overheated and to permit an increased number of cycles to be completed in a given period of time.

Abstract: A vented rotor for caliper disc brakes and the like includes an outer friction portion having two ring sections with a plurality of radially extending ribs extending therebetween. The ribs include support ribs extending from the hat wall, and secondary ribs space radially from the hat wall. The support ribs and secondary ribs fixedly interconnect the ring sections in a mutually parallel, spaced apart relationship in such a manner that the inner diameter of each the ring section is spaced apart from the hat wall. Vents are formed between the support ribs and secondary ribs. The vents have a constant cross sectional area along their length to enhance the airflow therethrough. As a result, cooling air is permitted to flow into the vents between the inboard and the outboard ring sections from both the inboard and outboard sides of the outer friction portion of the rotor, providing enhanced overall air flow past the ring sections.

Abstract: The present invention relates to an electromechanically operated disc brake for motor vehicles, which consists of a floating-type brake caliper as well as an actuating unit arranged on the caliper. The actuating unit exhibits an electric motor which adjusts an actuating element via a reducing gear. The actuating element in turn causes one of two friction linings provided in the brake caliper in a displaceable manner to be brought into engagement with a brake disc. In order to be able to maintain high clamping forces with very low electric power, the present invention proposes that means (20 or 21,22) be provided to prevent reverse rotation of the rotor (10) of the electric motor (6) when the current supplied to the electric motor (6) is switched off after said electric motor (6) was activated. At the same time, this measure minimizes heating of the electric motor.

This access plate allows entry into ports necessary to make brake applications from an electronic/programmed controlled unit or an equivalent thereof. This access plate has particular utility for accessing 26 porting and is one part of the entire unit that allows access to 26-type equipment for the purpose of overlaying features with an electronic controlled pneumatic braking system. This access plate provides access to porting to allow all of the advantages of electronic controlled braking to take effect such as shorter stopping distances, system performance feedback, and continuous recharging features. The present invention also provides a device on the access plate for accessing the necessary porting involved with doing a single car test within a 26-Type braking arrangement.

Abstract: A spring-actuated electromagnetic brake includes an adjustment plate attached a rotating shaft and having an annular recess in one end face thereof facing a boss of a brake plate slidably mounted on the rotating plate. An annular elastic member is disposed in the annular recess in such a manner that when the brake is in the released state, the elastic member partially projects from the recess and is in contact with an end face of the boss. A slide-distance adjustment bolt having an enlarged head and a thread-free shank of a length larger than the thickness of the adjustment plate extends through an opening of the adjustment plate and is threaded on the end face of the boss. The brake plate is slidable in one direction by the force of the brake spring and in the opposite direction by the recovery force of the elastic member. The range of sliding movement of the brake plate is determined by the difference between the length of the shank of the bolt and the thickness of the adjustment plate.
