  • Publication number: 20240083300
    Abstract: An electric energy dissipating system for a vehicle. The system includes an electric power system configured to be electrically connected to an electric traction motor of the vehicle and configured to receive and store electric power generated by the electric traction motor during braking, a fluid conduit, an air flow producing unit configured to provide a pressurized air flow through the fluid conduit, an electric machine, and a transmission arrangement. The electric machine is configured to be powered by the electric power system so as to drive the air flow producing unit via the transmission arrangement in order to dissipate energy from the electric machine. The transmission arrangement includes a first shaft and a second shaft. The first shaft is driven by the electric machine and the second shaft drives the air flow producing unit. The second shaft rotates at higher speed than the first shaft.

  • Publication number: 20240059153
    Abstract: An electric energy dissipating system for a vehicle. An air flow producing unit provides a pressurized air flow through a fluid conduit. A polyphase electric machine runs on a predefined number of phases. The air flow producing unit is mechanically connected to, and operated by, the electric machine. An electric brake resistor arrangement is located downstream of the air flow producing unit, and comprises one resistor unit for each one of said phases. An electric power system is configured to receive electric power generated by an electric traction motor during braking of the vehicle. The power system comprises an inverter which converts a DC input into a polyphase AC output. The electric machine and the resistor arrangement are electrically connected to the inverter in parallel, such that each phase of the AC output of the inverter is connected to a respective phase of the electric machine and to a respective resistor unit, in parallel.

  • Patent number: 10436107
    Abstract: An exhaust gas pressure regulator for a combustion engine includes a regulator housing and an inner diffuser assembly arranged inside the regulator housing so that an exhaust gas flow duct is formed between an inner surface of the regulator housing and an outer surface of the inner diffuser assembly. The inner diffuser assembly includes a front portion and a regulating piston that is moveable relative to the front portion and the regulator housing between an idle position in which the exhaust gas flow duct is open, and a pressurized position in which the regulating piston at least partly closes the exhaust gas flow duct. The inner diffuser assembly includes at least one throttled flow passage between the gas flow duct and an exhaust gas pressure chamber defined by the regulating piston and an interior surface of the front portion.
