摘要:
A brake system of a vehicle, with electromechanical service brakes on at least one axle designed without force sensors, having a control unit designed to control a braking operation for meeting a braking demand by activating the electromechanical service brakes of all the axles. An acquisition element on each of the electromechanical service brakes acquires a parameter from which a current brake touch point of the electromechanical service brake in question can be determined. For operating the brake system, the brakes on one of the axles of the vehicle are actuated during a braking operation. A current value of a brake touch point of the electromechanical service brakes on another axle that is currently not being used to provide the brake force of the ongoing braking operation is determined. An air gap of those electromechanical service brakes is set according to the current value of the brake touch point.

A method for controlling an electric pad wear compensator device of a disc brake arrangement, in particular for a motor vehicle, and a corresponding disk brake arrangement is provided. The disk brake arrangement includes control device that controls air clearance between a brake pad and a brake disk, a brake application device with a brake applicator lever coupled to the electric pad wear compensator device, and a readjustment spindle which receives at least a portion of the electric pad wear compensator device. The method for controlling the electric pad wear compensator device includes sensing the air clearance of the disc brake, comparing the detected air clearance with a preset value, and controlling the electric pad wear compensator device to adjust the air clearance to the preset value by energizing a solenoid of a coupling device of the electric pad wear compensator device during brake applicator lever movement.

An electric brake device comprises a caliper holding braking members and having an electric motor attached thereto, a reduction mechanism for transmitting an input rotation of one input element thereof from the electric motor to two output elements thereof at reduced speeds, a rotation-linear motion converting mechanism for converting the rotation of one of the output elements into a linear motion of one of the braking members, and a thrust force support member connected to the other output element and screw-engaged with the caliper, wherein the rotation-linear motion converting mechanism is supported by the thrust force support member to be movable together in a thrust direction and is provided with rotation limiting portions for limiting the rotation in a reverse direction of the one output element to a predetermined range, and wherein the thrust force support member is set to be greater in resistance to operation than the rotation-linear motion converting mechanism.

An anchor assembly is provided that permits adjustment of the brake shoes in a drum brake to account for wear. The assembly includes first and second adjuster shafts each having a plurality of threads and first and second pilot connectors. The pilot connectors each have a plurality of threads in engagement with the threads of a corresponding adjuster shaft. The pilot connectors each engage one end of a corresponding brake shoe. Rotation of each adjuster shaft causes longitudinal movement of a corresponding pilot connector in engagement with a corresponding brake shoe along an axis to adjust a position of the brake shoe.

A parking brake control device performs a releasing control with good precision by more precisely maintaining clearance between a friction-applying member and a friction-applied member. During a releasing control, a timing at which a braking force generated by an electric parking brake 2 drops to zero is detected based on a change in a motor current, and a second releasing operation time is set according to the magnitude of the motor current at the time the braking force drops to zero. This makes it possible for the second releasing operation time to be set in accordance with fluctuations in a motor load due to temperature changes or the like. Therefore, a clearance between a brake pad and a brake disc can be kept constant according to the motor load.

Disclosed herein are an apparatus and method of adjusting a clearance of an electronic brake, in which a clearance between a pad and a rotor is appropriately adjusted according to a vehicle traveling situation. If the entry condition of a clearance adjustment section during stoppage is satisfied, clearance adjustment is performed to move pads of an electronic brake away from a rotor by a rearward-movement adjustment distance during stoppage, enabling rapid braking-release so as not to prevent a driver from starting a vehicle due to brake failure. In addition, if the entry condition of a clearance adjustment section during traveling is satisfied, clearance adjustment is performed to move the pads forward or rearward according to a wheel slip value. The clearance adjustment during traveling is limited to the case of straight traveling, to prevent misjudgment due to wheel slip caused during cornering.

An electro mechanical or pneumatically actuated disk brake, in particular for a utility vehicle, includes a brake caliper or saddle and a brake disk. The brake saddle overlaps the brake disk at least in sections of the outer periphery thereof. The disk brake also includes a tensioning device which is entirely or partially inserted into the brake saddle. The tensioning device is used to produce a tensioning movement between the brake linings and the brake disk. The disk brake further includes at least one and preferably several adjusting devices. The brake disk and/or the brake saddle are arranged on a step with elastic pre-tension when the brake is in the release state.

A brake device is disclosed for rail vehicles. In at least one embodiment, the brake device includes an electromagnetic spring pressure brake, the brake force being applied by an elastic force to the part to be braked and a magnetic arrangement being provided for neutralizing the brake force. The magnetic arrangement counteracts the elastic force and consists of a coil arrangement and an armature place that are mobile in relation to each other, the mobile part being connected to the brake element that impinges the part to be braked. The brake device for a rail vehicle according to at least one embodiment of the invention allows a high brake force and short reaction times and is very compact. For this purpose, the mobile part is connected to an axially displaceable plunger which on one end can be impinged upon with the elastic force and which is connected on the other end to the brake element.
