HYBRID TRANSMISSION SYSTEM


  1. CONSTRUCTION


    1. An oil cooler is provided in the lower tank of the radiator assembly, ensuring ATF cooling performance. This suppresses ATF temperature rise during sporty driving, helping to enhance reliability.

    2. ATF is drawn from the oil strainer assembly using the oil pump, and divided into the cooling and the lubrication passages of MG1 and MG2. Through the cooling passage of MG1 and MG2, ATF is top fed directly to MG1 and MG2 after being cooled down in the oil cooler. In addition, ATF in the gear lubrication passage is also sent through the oil hole of the intermediate shaft to equally cool down the stator coil ends using centrifugal force generated by the rotation of the motor rotor shaft. This ensures excellent cooling performance.
