A rail-bound vehicle includes an energy storage device having a traction battery and a cooling device for cooling the traction battery using a coolant circulating in at least one coolant circuit. The energy storage device supplies a traction device of the vehicle with electrical energy. At least one air-conditioning device air conditions a passenger compartment of a car of the vehicle using a refrigerant circulating in a refrigerant circuit, and a control device controls the air-conditioning device. The air-conditioning device has a heat exchanger coupling the refrigerant circuit of the air-conditioning device to the coolant circuit of the cooling device of the energy storage device. The control device controls a flow of the refrigerant through the heat exchanger. An energy storage device, an air-conditioning device, an arrangement for cooling a traction battery and a method for controlling the arrangement are also provided.

A vehicle has a brake device with a friction brake unit, an electrical brake unit and a brake control device. In order to provide a vehicle having a reliable and structurally simple brake device, the friction brake unit has brake components made of a composite material and the brake control device includes a monitoring device for monitoring a brake operation performed by the electrical brake unit.

A drive protection device for protecting a traction drive in a vehicle, in particular a rail vehicle, includes at least one switching unit having an activation position and a deactivation position that protects the drive. A control unit is provided to trigger a transfer into the deactivation position, in at least one first operating situation, when an operating variable of the drive is in a critical region. In order to provide a drive protection device of this type, which can be used with a high degree of safety in as-wide-as-possible a range of operating situations of the vehicle, while still being simple to construct and cost-effective to implement, the control unit maintains the activation position, in at least one second operating situation, when the operating variable is in the critical region.

A compressed air system contains a compressed air reservoir, a compressed air line system and a drive system connected on an inlet side to the compressed air reservoir by way of the compressed air line system. The drive system has a drive and a drive controller, the drive system has a valve provided so as to pneumatically separate the drive controller from the drive.

An assembly for a vehicle, in particular a rail vehicle, includes an undercarriage unit having at least one first wheel set supported on a track and a main body supported on the first wheel set. The main body has a coupling mechanism for mechanically coupling to at least one car body of the vehicle. At least one first driving motor for driving the first wheel set, at least one power supply unit for supplying the driving motor with electrical power and at least one inverter unit are provided. The power supply unit is disposed at least partially in a region of the undercarriage unit in order to permit the undercarriage unit of the assembly to be expanded with regard to the functionalities of the undercarriage unit.

A current collector for a rail-mounted vehicle includes a collector arm and an insulation system which has insulating posts for the electrically insulating fastening of the collector arm on a vehicle roof element above an electrically grounded roof surface. In order to achieve a flatter roof structure, the insulation system includes an electrically insulating layer, which is disposed between the roof surface and the collector arm and is spaced apart from the roof surface by an air gap.

A voltage setting device has at least one multi-step voltage output, at least one power converter unit, which has at least one first power element that forms at least a part of a power converter branch, and a control unit that controls the first power element according to a first voltage step structure to provide a branch voltage. The power converter unit includes at least one second power element that, together with the first power element, forms the power converter branch and includes a group of modules, each with at least one energy storage device, a switch group and a module output. In a given control mode the control unit controls the group of modules to provide the branch voltage in cooperation with the first power element according to a second voltage step structure which is more detailed than the first voltage step structure.

Voltage setting device with multi-step voltage output

A motor drive circuit for a rail vehicle has a step-up converter, which is disposed at the input of the motor drive circuit, and which converts a mains DC voltage, at the input of the motor drive circuit into an intermediate circuit DC voltage. A pulse rectifier, which is downstream from the step-up converter, can be connected at the output to a drive motor of the rail vehicle and it is capable of converting the intermediate circuit DC voltage of the step-up converter into a motor drive voltage for driving the drive motor. A control unit activates the step-up converter in operation such that the converter generates the predetermined rated intermediate circuit DC voltage for a mains DC voltage below a predetermined rated intermediate circuit DC voltage as the intermediate circuit DC voltage. The control unit is designed such that it activates the step-up converter for a mains DC voltage above the rated intermediate circuit DC voltage such that the converter generates an intermediate circuit DC voltage identical to the mains DC voltage or an intermediate circuit DC voltage, which is greater at most by a predetermined offset value, and feeds the intermediate circuit DC voltage into the pulse rectifier.
