Document Type and Number:
WIPO Patent Application WO/2018/177384
Kind Code:
A1
Abstract:
A dual-clutch automatic transmission cooling lubricating hydraulic control system and a vehicle. The dual-clutch automatic transmission cooling lubricating hydraulic control system comprises a clutch lubricating control valve (15), the outlet thereof connecting to a clutch lubricating oil path, and a gear lubricating control valve (16), the outlet thereof connecting to a gear and bearing lubricating oil path. The inlet of the gear lubricating control valve (16) and the inlet of the clutch lubricating control valve (15) are connected in parallel to a first common port (19). The invention also comprises a mechanical pump (1) and an electric pump (11) respectively connected to a fuel tank. The outlet of the mechanical pump (1) and the outlet of the electric pump (11) are connected in parallel to a second common port (8). A cooling device (21) is disposed between the first common port (19) and the second common port (8). The dual-clutch automatic transmission cooling lubricating hydraulic control system has multiple operating modes and reduces defects such as a large displacement when only the mechanical pump operates.
