摘要：
A tension roller assembly includes a tension roller, a pivotable support arm, a tension arm, a compression spring, a rod, first and second spring stops, a mounting plate, and an overcenter assembly connected to an end of the tension arm. The overcenter assembly connects the tension arm to the mounting plate. The overcenter assembly is configured to make a pivoting movement over a pivot trajectory between engaged and disengaged positions. The overcenter assembly further has a center position located between the engaged and disengaged positions. The pivot trajectory between the center position and the disengaged position is divided into a tensioned section in which the end stop does not engage the stop surface and the spring exerts a force on the overcenter assembly, and a free-moving section in which the end stop engages the stop surface and the spring does not exert any force on the overcenter assembly.
