The three-element ferromagnetic magnetic flux-stator has two cylindrical disjoint surfaces with teeth and a body made of non-magnetic material. The rotors have an even number of poles - more than two. The cylindrical stator surfaces have a number of teeth, multiple of three, three for each two poles of the rotor. The magnetic fluxes of all the poles of the pole-rotor on the permanent magnets are closed through the main air gap, the ferromagnetic magnetic flux-stator and the second ferromagnetic rotor with teeth. The poles of the second rotor tend to orient themselves relative to the field so that the magnetic resistance for the force field lines is minimal, which leads to a synchronous rotation of the second rotor.EFFECT: increasing the transmitted torque.4 dwg

Brake shoe and braking unit // 2628555
FIELD: automotive industry.SUBSTANCE: brake shoe contains the arc-shaped base, having the outer side in the radial direction to install the brake pad and the inner side in the radial direction, opposite to the outer side. Several loops are also formed at the base near its first end. The loops are aligned along the axis and located at the distance from each other along this axis. Each loop is configured in such a way, that it is possible to insert the fastening pin inside it, by means of which the brake shoe can be attached to the brake mounting support with ability to turn. The fastening pin is fixed in the first and the second loops to prevent its movement relative to these loops. The brake unit contains the mounting support, the brake shoes and the drive actuator. The actuator movement causes the movement of the first and the second brake shoes between the engagement position with the brakes working surface and the position, when it does not contact the working surface.EFFECT: stability of braking and steering dynamics.20 cl, 6 dwg

Self-sealing synchroniser // 2627911
FIELD: machine engineering.SUBSTANCE: in the synchroniser, the pinion gear has a conical synchronising surface made in the pinion gear body from the inside with respect to its teeth coaxially to the pitch cylinder of the teeth. The blocking ring is mounted on the hub of the synchroniser with the possibility of axial movement and rotation relative to the hub by an angle determined by the thickness of the blocking tooth. The movement of the blocking ring relative to the pinion gear in the direction of its movement when the gear is actuated is limited by a spring retainer ring installed in the pinion gear.
