Title:
TENSIONER WITH SPRING FORCE CONTROL IN SECOND BORE
Document Type and Number:
Japanese Patent JP2019163862
Kind Code:
A
Abstract:
To provide a tensioner capable of improving the overall system behavior and efficiency while taking into account wear and stretching that occur in a chain.SOLUTION: The invention relates to a tensioner for tensioning a chain span which uses two pistons. Movement of the two pistons may be coupled together. The first piston provides damping to the chain span, and the second piston provides variable, dominant and automatically adjusting spring force to the chain span. The tensioner automatically adjusts the mean tension force to keep the chain tension as low as possible without sacrificing chain control, significantly improving drive efficiency at new chain conditions and conditions with dynamic loads.SELECTED DRAWING: Figure 1
