Transmission for reciprocating piston engine has oil sump with additional oil reservoir in connection with oil pump, and dry sump circuit for transmission component lubrication

摘要

The engine has an oil sump (1) with pump (9) for a main oil circuit (4). The oil sump has at least one additional associated oil reservoir (2), which is in active connection with the oil pump. There is at least one dry sump circuit (5) for lubrication of transmission components (3). The dry sump circuit is in connection with constants and a main shaft (6), the main circuit is in active connection with gear wheels (7) and/or a countershaft (8) and/or an oil cooling device. There may be a second oil pump (10), and the feed ratio between first and second pump is between 1.3 and 3.
