A brake system and a method of controlling the brake system including a pedal master unit, an electric booster unit, a pedal-feel generating unit, and an electric control unit, wherein the pedal master unit includes a master cylinder and an operating rod, the electric booster unit includes a motor, a motor piston, and a gear device-screw shaft combination, the pedal-feel generating unit includes a reaction disk configured to form a pedal feel force (F.sub.RD) and a pedal spring arranged to form a pedal feel force (F.sub.spring), and the electric control unit is configured to variably control, in a regenerative braking mode and in a hydraulic braking mode, a ratio of increase to decrease of the pedal feel force (F.sub.RD) and a ratio of increase to decrease of the pedal feel force (F.sub.spring).

A system with a vertically adjustable telescoping pole assembly and cramp brake mechanism includes a telescoping pole assembly with at least an outer pole and an inner pole. The pole assembly is movable bi-directionally between a closed position and an extended position. The cramp brake mechanism has a body that is secured to the outer pole of the pole assembly, and also includes a brake that releases while the pole assembly is moved to the extended position and engages when the assembly is not being moved.

Power lines are installed with a rope brake apparatus that enables a rope to be suspended above the ground during installation and that thereby eliminates the need to block off the ground between power poles. The rope brake apparatus has a pair of opposed cam cleats mounted on a base adjacent each other for allowing movement of a rope between them in one direction and for preventing movement of a rope between them in an opposite direction.

A tray device for a vehicle includes a tray having a storage space capable of storing an article, a tray cover rotatably installed on the tray to open and close the storage space and including a coupling plate having a heart cam groove, and a locking device fixedly installed on an outer surface of the tray.

A system includes a carriage configured to move along a rail. The system also includes a clamping brake configured to selectively allow and prevent movement of the carriage along the rail. The clamping brake includes multiple brake pads configured to be moved inward to lock onto the rail and to be moved outward to release the rail. The clamping brake also includes multiple springs configured to apply spring forces that cause the brake pads to move inward and lock onto the rail. The clamping brake further includes a camshaft coupled to or including multiple eccentrics. The eccentrics are configured to overcome the spring forces and cause the brake pads to move outward and release the rail.

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.

An electromagnetic rail brake device of a rail vehicle having at least one brake magnet which has a magnet coil body and at least one magnetic core, and wherein the magnet coil body carries at least one magnet coil winding, and having an electric connector device, by way of which the at least one magnet coil winding is supplied with current, wherein the electric connector device has at least one pin-shaped electric connector body which is connected via a releasable electric connection to at least one current-conducting electric cable which is guided from the outside to the at least one pin-shaped connector body in relation to the brake magnet. The at least one pin-shaped electric connector body may be arranged on a free and outer surface of the magnet coil body or an element which is connected to the magnet coil body.

Provided is a braking device for a driving shaft, and the braking device includes: a brake ring coupled to the driving shaft in such a manner as to rotate according to rotation of the driving shaft and having one or more locking pieces with cross-shaped ends; a support frame fixed to an interior of a robot articulation; brake wings rotatable around brake shafts formed on the support frame and having locking protrusions adapted to stop the rotation of the driving shaft through physical interference with the cross-shaped ends of the locking pieces of the brake ring; position regulators adapted to rotate the brake wings to allow positions of the locking protrusions to be moved; and elastic members adapted to apply elastic forces to the brake wings rotating.

A cable-braking apparatus includes a main body unit at which a main cable is positioned, a drive unit provided at the main body unit so as to generate a drive force, an elastic compression unit configured to compress or release the main elastic element using the drive force generated by the drive unit, a press unit actuated by the elastic compression unit so as to move a press plate thereof to thus press the main cable, and a movement control unit configured to lock or release an anchor pin to thus control movement of the press unit. The main elastic elements are compressed and released by the action of the gear train and the clutch, thereby offering an effect of preventing malfunctions.

A rotation locking device 4 has a locking gear 5; a reverse input blocking clutch having an input member 12 and an output member 13; and an engaging member 8, and switches between a first mode where an engaging claw portion 14 engages with an engaging concave portion 9 by the output member 13 rotating the engaging member 8 due to the input member 12 being rotationally driven, and rotation of the locking gear 5 is restricted, and a second mode where engagement between the engaging claw portion 14 and the engaging concave portion 9 is released and rotation of the locking gear 5 is allowed.
