Patent ID: 10557529

Abstract:
A traction mechanism tensioning unit (1) for a traction mechanism drive of a motor vehicle is provided. The traction mechanism tensioning unit (1) includes a housing (2) in which a hydraulic tensioner (3) is arranged, the hydraulic tensioner (3) has a cylinder element (4) connected rigidly to the housing (2), in which an axially moving piston (5) is arranged, a compression spring (18) is arranged for generating an axial tensioning force on the piston (5) in a compression chamber (6) formed between the cylinder element (4) and the piston (5), and the hydraulic tensioner (3) is fluidly connected to a pressurized medium supply line (8) via a pressure control valve (7) arranged in the housing (2) for realizing a constant pressurized medium pressure in the compression chamber (6).
