A flywheel energy storage mixed type superconducting magnetic bearing is composed of a stainless steel spindle (1), a radial electromagnetic bearing stator (2), a low-temperature Dewar (3), a superconducting bearing permanent magnetic rotor (4), a superconducting bearing block stator (5), a superconducting bearing coiling stator (6), a superconducting bearing iron magnetic suction force disk rotor(7), a flywheel (8)m a radial electromagnetic bearing iron magnetic ring rotor (9) and a superconducting bearing iron core magnetic yoke (10). The superconducting bearing block stator (5) and the superconducting bearing coiling stator (6) are arranged inside the low-temperature Dewar (3) and installed on the stainless steel spindle (1) in a sleeving mode, and liquid nitrogen or a refrigeration machine is used for cooling. The superconducting bearing coiling stator (6) is arranged below or around the superconducting bearing block stator (5). The radial electromagnetic bearing stator (2) is installed on the upper portion of the stainless steel spindle (1) in a sleeving mode. The superconducting bearing iron magnetic suction force disk rotor (7) is installed outside the low-temperature Dewar(3) and installed on the stainless steel spindle (1) in a sleeving mode.

The invention relates to the technical field of design vehicle braking, in particular to a city bus wheel edge disc braking and flywheel energy-storage integrated braking device. Wheel hubs are fixedly connected with half axles through half axle flanges, car tires and the wheel hubs rotate together with the half axles, electromagnetic clutches are used for controlling connecting or separating of energy-storage flywheels and the half axles, when a disc brake in a car conducts braking, the electromagnetic clutches are jointed, the car tires drive the energy-storage flywheels to rotate, and when the rotating speed of the energy-storage flywheels is higher than the rotating speed equivalent of the car tires, connection between the energy-storage flywheels and the car tires is broken off; and when the car is started, the electromagnetic clutches are jointed, the energy-storage flywheels provide auxiliary driving moment for the car tires, when the rotating speed of the energy-storage flywheels is lower than the rotating speed equivalent of the car tires, the electromagnetic clutches are separated, and connection between the energy-storage flywheels and the car tires is broken off. The city bus wheel edge disc braking and flywheel energy-storage integrated braking device integrates the functions and the advantages of drive-by-wire disc friction braking and flywheel energy storage, the structure is compact, response is rapid, and energy storage is efficient.

The invention discloses a superconducting magnetic suspension bearing mechanism. The mechanism is composed of a permanent magnet and two identical superconducting closed windings which are arranged along a coaxial line, and the two superconducting closed windings are symmetrically arranged on two sides of the permanent magnet; in addition, a permanent magnet ring coaxially arranged can be connected with the exterior the permanent magnet in a sleeving mode, the permanent magnet and the permanent magnet ring are not contacted, and the magnetization direction is the same as that of the permanent magnet; and when in use, the two superconducting closed windings and the permanent magnet ring are rigidly fixed on a suspension system bracket respectively, and the permanent magnet is coaxially connected with a working rotor supported by the permanent magnet. The mechanism can be applied to the fields of flywheel energy storage and the like, and operation loss caused by mechanical friction is reduced.
