Disclosed herein is an electromagnetic brake system. The electromagnetic brake system includes a brake disc configured to be rotated together with a drive shaft of a drive motor configured to operate a vehicle wheel, an armature disc configured to be movable so as to be in close contact with or so as to be separated from one side of the brake disc, an elastic member configured to elastically press the armature disc to the one side of the brake disc to a direction in which the armature disc is in close contact with the brake disc, and an inductor configured to separate the armature disc from the brake disc by an electrical signal. The brake disc includes a tube portion mounted on the drive shaft, and a plate portion provided to extend in an outward direction of the tube portion to be opposite to the armature disc. The tube portion and the plate portion are provided as a single member in which the tube portion and the plate portion are integrally formed with each other.

A disc brake system includes a first brake pad having a first type of friction material, a second brake pad having a second type of friction material different from the first type of friction material, and a poshrod arrangement configured to apply force in varying amounts on both the first brake pad and the second brake pad, the poshrod arrangement comprising an actuator movable to different, positions relative to the first brake pad and the second brake pad to vary a percentage of total braking force applied by the first brake pad and the second brake pad. A method for braking a vehicle is also provided.

The present disclosure relates to an automotive slide member including a first slide portion having a first lubricant applied between first portions of a first friction slide mechanism, and a second slide portion having a second lubricant applied between second portions of a second friction slide mechanism. The first slide portion is arranged at a part to be touched by an operator who attaches the automotive slide member to an automobile or a user of the automobile. The second slide portion is arranged at a part that is not touched by the operator who attaches the automotive slide member to the automobile or the user of the automobile. The second lubricant contains a relatively larger amount of conductive carbon than that of the first lubricant.

The aim of the invention is to ensure a reliable lift of both brake pads of a floating-caliper brake (1) after releasing the brake. This is achieved in that a lifting part (20) is hinged to the brake caliper (2) at a hinge point (21), and the lifting part (20) is supported on the support structure (7) at a contact point (23) at least partly at releasing the floating-caliper brake (1), wherein a lift drive (22) is provided which rotates the lifting part (20) about the hinge point (21) such that a support for the lifting part (20) is produced on the contact point (23), whereby the hinge point (21) and the brake caliper (2) are moved.

A brake piston is described. The brake piston is configured for use in a disk brake system, the piston comprising: a body having an outside width perpendicular to a central axis; a footing disposed at a distal end of the piston; wherein the footing is configured to exert force on a brake pad during actuation of the disk brake system; the footing having a face configured to contact the brake pad, the face having a length and a width, wherein the length is longer than the outside width of the body, and the length is greater than the width.

A caliper guide assembly having a guide pin, a guide bore, a cap, and a sensor arrangement. The guide bore is arranged to receive the guide pin. The cap may be secured to an open end of the guide bore proximate a free end of the guide pin. The sensor arrangement may include a first sensor component that is configured to provide an output indicative of relative axial displacement between a first sensor component and a second sensor component.

Disclosed herein is an electromagnetic brake system. The electromagnetic brake system includes a brake disc configured to be rotated together with a drive shaft of a drive motor configured to operate a vehicle wheel, an armature disc configured to be movable so as to be in close contact with or so as to be separated from one side of the brake disc, an elastic member configured to elastically press the armature disc to the one side of the brake disc to a direction in which the armature disc is in close contact with the brake disc, and an inductor configured to separate the armature disc from the brake disc by an electrical signal. The brake disc includes a tube portion mounted on the drive shaft, and a plate portion provided to extend in an outward direction of the tube portion to be opposite to the armature disc. The tube portion and the plate portion are provided as a single member in which the tube portion and the plate portion are integrally formed with each other.

Disclosed is an elevator machine including: a plurality of stationary structures, including a proximate stationary structure and a distal stationary structure, a brake support that comprises the proximate stationary structure, a brake disc rotably supported in the brake support intermediate the plurality of stationary structures, the plurality of stationary structures and the brake disc each including a respective one of a plurality of orifices, and the plurality of orifices being mutually aligned and offset from a rotational axis of the brake disc to removably receive an elongated bar, wherein when the bar is positioned in the plurality of orifices, the brake disc is prevented from rotating, thereby preventing vertical movement of an elevator car in an elevator hoistway.

A brake and method of assembly are provided. The brake includes a friction plate configured for coupling to a rotatable body for rotation with the rotatable body about an axis of rotation, a pressure plate disposed about the axis on a first side of the friction plate and fixed against rotation, and an armature plate disposed about the axis on a second side of the friction plate. An electromagnet is disposed about the axis on an opposite side of the armature plate relative to the friction plate. A spring biases the armature plate in a first axial direction towards the friction plate and away from the electromagnet to engage the brake. A fastener couples the pressure plate to the electromagnet. The fastener conforms to a space between opposed surfaces of the pressure plate and the electromagnet and, upon hardening, bonds the pressure plate to the electromagnet.

A sealed hydraulic stop valve for caliper guide system of an air disk brake system provides a means of continuous maintenance and lubrication. The system includes a tubular guide pin, a cap, a sealed hydraulic stop valve, and a plurality of lubricating grooves. The tubular guide pin attaches a caliper head to a carrier of the air disk brakes. The lubricating grooves inject grease into the system and are radially distributed about the tubular guide pin. Each lubricating groove normally and externally traverses into the tubular guide pin. The cap and the stop valve seal off the tubular guide pin and allow for grease injection to the lubricating grooves. The cap is concentrically positioned about the tubular guide pin. The stop valve is adjacently integrated into the cap, opposite to the tubular guide pin. Resultantly, the stop valve is in fluid communication with each of the lubricating grooves.
