WIPO Patent Application WO/2021/093836
Kind Code:
A1
Abstract:
A dual-arm tensioner, for use in an internal combustion engine in which a power generation-electric motor unit is assembled. The internal combustion engine comprises a crankshaft pulley (30); a power generation-electric motor unit pulley (50); and an annular transmission member (20), wrapping around the crankshaft pulley (30) and the power generation-electric motor unit pulley (50). The dual-arm tensioner comprises a first tensioning arm (13) and a second tensioning arm (14). The first tensioning arm (13) is provided with a first pivoting center (15) and the first tensioning arm (13) can pivot around the first pivoting center (15). One end of the first tensioning arm (13) is provided with a first tensioning pulley (11). One end of the second tensioning arm (14) is pivotally hinged to the first tensioning arm (13) around a second pivoting center (16). The second pivoting center (16) deviates from the first pivoting center (15). The other end of the second tensioning arm (14) is provided with a second tensioning pulley (12). A torsion spring (19) is provided between the first tensioning arm and the second tensioning arm and enables the first tensioning arm and the second tensioning arm to deflect around the pivoting center of the second tensioning arm (14) in the direction close to each other. The first pivoting center (15) is provided outside the wrapping range of the annular transmission member (20).
