The invention discloses a
hydraulic control oil way for a rear-drive DHT
hybrid transmission with controllable motor cooling flow, and belongs to the technical field of
hybrid automobile transmissions. The mechanical
gear pump and the electronic
gear pump are connected in parallel, the oil inlet end is communicated with the oil cavity, and the oil outlet end is communicated with the first oil way; the first oil way is communicated with a main
oil pressure adjusting valve set, an
electromagnetic valve pressure limiting valve set, a
brake electromagnetic valve and a
clutch electromagnetic valve. The main
oil pressure regulating valve group is communicated with the second oil way, the cooler, the front-end friction pair, the rear-end friction pair and the main
oil pressure control electromagnetic valve; the electromagnetic valve pressure limiting valve group is communicated with the main oil
pressure control electromagnetic valve and the cooling flow control electromagnetic valve; the flow regulating valve group is communicated with the cooling flow control electromagnetic valve, the cooler, the generator and the driving motor; the
brake electromagnetic valve is communicated with the
brake; the
clutch electromagnetic valve is communicated with the
clutch; the technical effects that the cooling flow of the driving motor and the generator is dynamically and accurately regulated and controlled,
system redundancy is reduced, the manufacturing cost is reduced, and the
overall efficiency of a hydraulic
system is improved are achieved.
