  • Publication number: 20220178378
    Abstract: A transmission includes a transmission housing member, a ring portion, a high speed shaft, a third roller, and a third plate bearing, which rotatably supports the third roller. The transmission housing member includes a first supporting surface, which restricts the third roller to a first position, and a second supporting surface, which restricts the third roller to a second position. The third roller is moved within a movement range from the first position to the second position. The movement range includes a specified range in which the third roller is not supported, in a radial direction of the high speed shaft, by the transmission housing member with the third plate bearing in between, but is supported by being held between the ring portion and the high speed shaft.

  • Patent number: 10994589
    Abstract: An electric vehicle includes an electric motor, an electrical storage device, an air-conditioning apparatus and a controller. A coolant circuit of the air-conditioning apparatus has a compressor, an outdoor heat exchanger, an expansion valve for cooling, and an evaporator. The evaporator has a heat storage member. In a case in which regenerative braking by the electric motor is performed when the state of charge of the electrical storage device is the predetermined value or more, the controller controls the air-conditioning apparatus such that a temperature of the evaporator is decreased so as to be lower than a temperature of the evaporator when a state of charge of the electrical storage device is less than a predetermined value.

  • Patent number: 10913331
    Abstract: A motor-driven vehicle includes an electric motor, a power storage device, a control device, and a refrigerant circuit. The refrigerant circuit has a compressor, an indoor heat exchanger, an expansion valve, and an outdoor heat exchanger. The indoor heat exchanger exchanges heat with the refrigerant compressed by the compressor. The refrigerant which passes through the indoor heat exchanger is decompressed by the expansion valve, and the outdoor heat exchanger exchanges heat with the decompressed refrigerant and allows the refrigerant to return to the compressor. When the remaining capacity of the power storage device is equal to or more than a predetermined value, the control device operates the compressor and decreases a passing-through air volume of a first air guide device that controls a passing-through air volume of the outdoor heat exchanger.

  • Publication number: 20190161068
    Abstract: A multiple drive source-equipped vehicle includes two temperature detection parts configured to detect a temperature of external air. When a heating operation is performed at a time of vehicle driving by a first drive source, the controller determines whether or not an external air temperature is lower than a predetermined value based on a detection temperature of a temperature detection part of which a detection temperature is higher among the two temperature detection parts. The controller continues a heating operation by a first heating apparatus when it is determined that the external air temperature is not lower than the predetermined value. The controller operates the second drive source and performs a heating operation by a second heating apparatus when it is determined that the external air temperature is lower than the predetermined value.

  • Publication number: 20180334014
    Abstract: A control unit, at the time of a heating operation, pressure-reduces refrigerant that has passed through an indoor condenser, by an expansion valve, and thereafter introduces the refrigerant into an outdoor heat exchanger to thereby perform heat exchange with outside air. Further, the control unit, at the time of a defrosting operation, introduces high-temperature and high-pressure refrigerant compressed by a compressor into the outdoor heat exchanger to thereby remove frost adhering to the outdoor heat exchanger. Furthermore, the control unit determines whether to perform the defrosting operation or not, based on the amount of electric power required for the defrosting operation.
