Abstract

The invention relates to a tensioning device, in particular to a bidirectional association bidirectional tensioning device with a variable damping device. The bidirectional association bidirectional tensioning device with the variable damping device comprises a base, a first tensioner, a second tensioner and the associated belt variable damping device, wherein the first tensioner is rotatably arranged on the base; the second tensioner is rotatably arranged on the base; and one end of the associated belt variable damping device is rotatably connected to the first tensioner, and the other end of the associated belt variable damping device is rotatably connected to the second tensioner. The first tensioner and the second tensioner are located on the two sides of the base correspondingly. The associated belt variable damping device can be compressed and provide variable damping.

Description

technical field

[0001] The invention relates to a tensioning device, in particular to a bidirectional tensioning device with bidirectional association and a variable damping device. Background technique

[0002] Under the requirement of higher and higher energy utilization efficiency of automobiles, mild-hybrid engines with start-stop technology have become the mainstream, and cars with start-stop technology driven by belts generally need to use MGU motors. The function of the MGU motor itself determines that it can not only output power for the engine, such as working as a starter motor and a booster motor, but also convert the kinetic energy of the engine into electrical energy, such as consuming engine power as a generator to generate electricity and as a motor when the engine decelerates. When the energy recovery motor is working. Thus, in a belt drive drive system, there are two drive sources: the crankshaft pulley and the MGU motor pulley. When these two driving sour...
