A parking brake, particularly for a vehicle, includes a brake piston, supported to be movable along a longitudinal axis between a braking position and an open position, by which a brake disk is immobilizable by applying a braking force, when the brake piston is in the braking position, a drive unit for moving the brake piston along the longitudinal axis, and a toggle lever interacting with the brake piston and having at least first and second legs. The first and second legs are connected rotatably with a joint element and are actuatable by the drive unit, such that the toggle lever provides the braking force and applies it to the brake piston. An immobilizing device having such a parking brake, as well as a vehicle having the immobilizing device, and a method for immobilizing a vehicle by such an immobilizing device are also provided.

A device configured for insertion between two parts of a rotary wing aircraft that are likely to undergo a repeated relative movement. The device includes at least two frame elements intended to be mounted on at least one of the two parts of the aircraft, and at least one layer of elastomer positioned between the two frame elements, the at least one layer defined by a first surface belonging to the inner volume of the device, a second surface also belonging to the inner volume of the device, and an outer surface not belonging to the inner volume of the device. The inner volume of the device includes at least two independent pouches each positioned at a predetermined distance from the outer surface, each pouch being filled with a product capable of flowing outside its pouch when a crack has spread from said outer surface toward the pouch in question.

A brake assembly includes a service brake assembly and an electromechanically actuable parking brake assembly. The electromechanically actuable parking brake assembly has a ball nut assembly comprising a ball screw and a ball nut. The ball screw and ball nut form a raceway for bearing members. The bearing members circulate within an internal path formed in the ball screw.

The invention relates to a disc-type brake which can use the energy of a transport machine during its traveling to brake, has a huge self-energizing action and is used for a motorcycle, a car, a truck, a train and an elevator. The brake has a very small control force (power), is simple and reliable and has a small volume. The brake is very easily designed as an electrically controlled disc-type brake system (EMB), the power and volume of an electrically controlled motor of the brake can be several timesmore than a dozen of times less than that of an electrically controlled motor in the prior art, after its promotion, the brake can greatly improve the safety of the car and the motorcycle. The brake can reduce many parts, components and mechanisms and save much cost and bring us tremendous social and economic benefits and is a landmark brake.

An object of the present invention is to obtain a brake system that can generate appropriate braking force without influence of temperature. A brake system includes: a piston that presses pressing members; a motor that moves the piston; a current detection unit that detects current flowing in the motor; a storage unit that stores a correspondence relation between idle running current and motor stopping current; a motor stopping current setting unit that sets the motor stopping current using the storage unit and the idle running current; and a control unit that stops to supply the current to the motor when the current flowing in the motor reaches the motor stopping current. The correspondence relation is set so that the rate of change of the motor stopping current relative to the idle running current becomes smaller when the idle running current is small than that when it is large.

An electromagnetic active brake which is de-energized in the brake standby state, includinga brake body (1),a brake device with at least two opposing brake shoes (9, 12) which are spaced from a component to be braked in the de-energized state of the active brake,and an electromagnet (5) which is arranged in the brake body (1) and the armature (6) of which interacts with a brake lever (2). The armature (6) of the electromagnet (5) is rigidly connected to a spring compressor (3) which is guided in the brake body (1) and which is moved by the armature (6) in the axial direction of the armature (6) when the electromagnet (5) is energized and in this manner clamps a spring (16) against an abutment (20) that interacts with the brake lever (2) and is arranged in an axially adjustable manner in the direction of the path of the spring compressor (3). The active brake according to the invention is highly energy-saving and thus economical.
