    摘要： A self-adjusting supporting head comprises a vehicle body lifting column (10) and a load-bearing detection device arranged on the vehicle body lifting column (10). The load-bearing detection device comprises a spring supporting plate (5), a spring (6), a limiting switch tip (8), a load limiting switch (9) and a floating load-bearing adjusting device. The floating load-bearing adjusting device comprises a floating load-bearing block (1), a floating load-bearing block mounting base (2) and a floating connector. The floating load-bearing block is in spherical fit with the floating load-bearing block mounting base. The floating load-bearing block can swing in random directions above the floating load-bearing block mounting base according to the specific state of a steel plate in contact with the floating load-bearing block. When the heights of a plurality of steel plates welded on the side beam of a vehicle are not inconsistent, the floating load-bearing block can automatically correct according to the steel plates through a spherical fit structure, so as to realize that the upper surface of the floating load-bearing block is in complete contact with the steel plates, and ensure that the side beam of the vehicle is uniformly stressed and the vehicle is not damaged.

    摘要： A system and a method for parallel power supply control for auxiliary converters of a motor train unit in the presence of interconnecting lines. The system comprises multiple three-phase inverter modules. The multiple three-phase inverter modules are in parallel connection with each other. Any two-phase circuit of a three-phase inverter module is separately in parallel connection with a corresponding two-phase circuit of a three-phase inverter module adjacent to the three-phase inverter module by using a connecting line module. The connecting line module is connected to a control system. The three-phase inverter modules are also connected to the control system. The three-phase lines of the three-phase inverter modules are all provided with switches. Less interconnecting lines are used, and any two phases of the three-phase inverter modules are separately in parallel connection, and therefore, stable power supply is achieved by balancing currents of any two phases of the three-phase circuits, and the system reliability is improved.

    摘要： The present application relates to the technical field of field bus communication, and in particular to a protocol converter between a CPCI bus and an ISA bus and a conversion method thereof, which are suitable for communication between railway vehicle CPUs and vehicle bus MVB devices. The protocol converter comprises a CPCI local bus interface extension timing module, an ISA bus interface timing module, a CPCI bus matching ISA bus timing interface module, and a clock management module. The CPCI bus realizes communication with the ISA bus by the protocol converter. The traditional conversion bridge chips are replaced with the protocol converters without changing the traction controller structure and other devices in the system; the flexibility is high; and the functions are diverse. In addition, 8-bit data width or 16-bit data width of the ISA bus is supported, and the operation of an ISA bus device by a CPCI bus device in the form of IO or in the form of MEMORY is supported.

    摘要： Provided is a hand brake, comprising a hand wheel (4), a chain (5), an enclosure (1), a drive shaft assembly (3) which is disposed in the enclosure (1), bull gear (13), and base assembly; the hand wheel (4) is connected to the drive shaft assembly (3), one end of the chain (5) is fixed to the bull gear (13) by means of rivets, and the main shaft of the bull gear (13) is a chain winding shaft (2). The hand brake further comprises a limiting device disposed on the chain winding shaft (2) between the bull gear (13) and the base (22); the limiting device comprises a bearing I (10), a torsion spring holder (12), a torsion spring (11), a guide plate (9), and a guide plate holder (23); the torsion spring (11) is sleeved on the outside of the bearing I (10). a stopper post III (7) is secured to the side of the torsion spring holder (12) facing the spring; a stopper post I (8) is secured to the side of the guide plate (9) facing the torsion spring (11); a stopper post II (26) is secured to the side of the base (22) facing the guide plate holder (23); the stopper post II (26) passes, by means of a hole, through the guide plate holder (23) and rotates in the arcuate groove of the guide plate (9). The center distance between the drive shaft (16) and chain (5) which is on end of the chain winding shaft (2) is increased by 47 mm; installing the hand brake not only prevents the problem of the chain interfering with the movable pulley when the hand brake is deployed and thus affecting the performance of the hand brake, but also provides for a better appearance.
