A combined drive / brake unit (100) integrated into the rim (111) of a wheel (112) includes an axial flux motor (118) and an eddy current brake (120), wherein a common rotor (106) is provided for the axial flux motor (118) and the eddy current brake (120).

The rail vehicle secondary suspension system connects the bogie and the carriage floor, and comprises a height adjustment mechanism fixed to the bogie and a rubber vibration isolator fixed to the carriage floor. The height adjustment mechanism comprises a box body fixed to the bogie and filled with lubricating grease or lubricating oil, an electric worm gear installed in the box body, and an expansion piece installed in the box body in the vertical direction and having a self-locking function. The expansion piece is in transmission connection with the electric worm gear, and is fixed to the rubber vibration isolator and is extended and retracted with the transmission of the electric worm gear to drive the rubber vibration isolator to rise and fall. The present application ensures the consistency of the height of the carriage floor after adjustment, avoids the inclination and deflection of the floor caused by different loads, improves the convenience, accuracy and reliability of the height adjustment of the carriage floor, has a simple structure, light weight, low manufacturing and maintenance cost, keeps the normal height of the carriage floor during the load process, ensures the stability of the vehicle during driving, and improves the riding comfort. The present application also provides a height adjustment method of the carriage floor.

This invention relates to a pneumatic solenoid valve (10), particularly to a compressed air device (30) for a vehicle (50), comprising: an electromechanical actuator unit (11) having an energized coil, a magnetic core (12), and a movable armature (13); a valve housing (14) having a first compressed air connector (15) forming a compressed air inlet and a second compressed air connector (16) forming a compressed air outlet; and a valve cavity (17) having a valve seat (18) at the first compressed air connector (15), wherein the valve seat (18) is movable by means of a valve seat arranged on the armature. (13) is sealed by the sealing element (19); wherein: the electromechanical actuator unit (11) has an armature guide (20) in which the armature (13) can translate, the armature guide (20) is movably arranged in the valve housing (14) and connected to the magnetic core (12); and the pneumatic solenoid valve (10) is designed to cause a first partial stroke (H1) of the armature (13) when the coil is energized to lift the sealing element (19) from the valve seat (18) and to allow the compressed air flow (L) flowing in at the first compressed air connector (15) to pass through. ein This causes the armature guide (20) and the magnetic core (12) to travel, and results in a second travel (H2) of the armature (13). The invention also relates to a vehicle compressed air device (30) and a vehicle (50) having the compressed air device (30).

The invention discloses a device and method for monitoring the blocking state of an urban gutter inlet. The device comprises a data processing unit, a waterproof microphone, a humidity sensor, a liquid level sensor, an LED state indicator lamp, a protective shell and a data transmission interface, and the data processing unit is connected with the humidity sensor, the waterproof microphone and the liquid level sensor. The method comprises the steps of training a blockage judgment model of sound features, installing and setting a monitoring device, judging and processing blockage, early warning accumulated water, resetting dormancy and the like. According to the invention, the defects of low labor efficiency, high misjudgment of a single sensor and large interference of light environment on vision in the existing gutter inlet blockage monitoring are overcome.
