摘要： The present disclosure discloses a rail vehicle. The rail vehicle includes: a plurality of bogies, where the bogie has a straddle recess suitable for straddling a rail; and a vehicle body, where the vehicle body is connected to the plurality of bogies and pulled by the plurality of bogies to travel along the rail, and the vehicle body includes a plurality of compartments hinged sequentially along a length direction of the rail; the plurality of compartments forms at least one compartment group, the compartment group includes three compartments hinged sequentially, and the bottom of each of only compartments that are located at two ends of the compartment group and that are of the three compartments is connected to the bogie; and in the length direction of the rail, a surface that is of a compartment at at least one end of the vehicle body and that faces away from an adjacent compartment is provided with an escape door that can be opened and closed. The rail vehicle according to this embodiment of the present disclosure facilitates optimization of the structure of an escape passage, reduction in occupied space and the weight borne by the rail, and improvement in stability, and is flexible in steering and low in costs.

摘要： The systems and methods described herein include monitoring systems and methods that monitor speeds of a motor of a vehicle represented as a pulse signal indicative of a rotational position of the motor. The systems and methods include receive a pulse signal from a speed sensor coupled to a traction motor. The pulse signal is indicative of a rotational position of the traction motor. The systems and methods include analyze the pulse signal to identify per-revolution signal reoccurrences that meet designated criteria, and determine a defect based on the per-revolution signal reoccurrences that are identified. The defect is one or more of a wheel defect, a bearing defect, or a gear defect.

摘要： A motor suspension assembly includes a frame bracket configured to be coupled with a vehicle frame having mounting locations for upper and lower suspension bars that are positioned for a direct current (DC) traction motor to rest upon the upper suspension bar and for elastic pads to be disposed between the upper and lower suspension bars. The frame bracket is configured to be coupled with the vehicle frame in place of at least one of the upper suspension bar or the lower suspension bar. The assembly also includes a dog bone suspension link configured to be coupled with a nose bracket of an alternating current (AC) traction motor and the frame bracket. The dog bone suspension link is configured to absorb vibration by at least partially rotating about one or more of the nose bracket or the frame bracket during operation of the AC traction motor.

摘要： A monorail vehicle includes a chassis supporting a vehicle body that includes a passenger floor, a first side wall, and a second side wall and first and second propulsion systems. Each propulsion system includes an electric motor and a drive wheel coupled to a rotor of the electric motor. Each electric motor and the drive wheel coupled to the rotor of the electric motor are positioned on both sides of an imaginary plane extension of the passenger floor. First and second shells cover portions of the first and second propulsion system. The first shell is positioned proximate to the first side wall and defines a first space between the second side wall. The second shell is positioned proximate to the second side wall and defines a second space between the first side wall.

摘要： A monorail vehicle includes a chassis supporting a vehicle body, that includes a passenger floor and at least one side wall, and an electrical motor supported by the chassis. A drive wheel is coupled to a rotor of the electric motor with a rotation axis of the drive wheel substantially coaxial with an axis of the rotor. Portions of the drive wheel and the electric motor are positioned on both sides of an imaginary plane extension of the passenger floor. The drive wheel and the electric motor are covered by a shell that is integral to one side of the vehicle body and which defines a space between the other side of the vehicle body.
