Crankshaft for e.g. petrol engine of motor vehicle, has collection and channelization unit collecting and channelizing lubricant flowing from big-end bearing at level of crank pin and including channel provided on flange of crankshaft

摘要

The crankshaft (1d) has a crank pin and a collection and channelization unit for collecting and channelizing lubricant flowing from a big-end bearing at a level of the crank pin. The unit includes a channel (7d) provided on a flange (4) of the crankshaft, where an end of the channel opens at a periphery of the flange. The channel extends radially from the crank pin along a symmetrical plane (10) of the flange or extends at back of the symmetrical plane of the flange relative to displacement of the flange during rotation of the crankshaft. An independent claim is also included for a mobile coupling system comprising a connecting rod.
