Abstract

Technical Field
[0001] The utility model belongs to the technical field of engines, and in particular relates to a forced lubrication thrust plate structure. Background Art
[0002] In the engine field, a common crankshaft axial positioning method is to use a crankshaft thrust plate. The thrust friction pair is splash lubricated. During the operation of the engine, the lubricating oil of the crankshaft main journal is splashed onto the thrust plate and the crankshaft thrust boss under the action of the rotating centrifugal force to form a lubricating oil film. The ideal lubricating oil film can greatly reduce the friction during the operation of the thrust plate friction pair, and take away the heat generated by the friction, so that the thrust plate is in an ideal working state.
[0003] At present, the heavy-duty engine market demands more automatic transmission models. Compared with manual transmission models, automatic transmission models have larger clutch separation force, and most of the clutches in the current market are push-type clutches. Ordinary thrust plates cannot meet the high separation force. We specially design a forced lubrication thrust plate structure and a thrust plate surface shot blasting treatment to solve this problem.
