Description

technical field

[0001] The invention relates to the field of automobile transmissions, in particular to an automatic transmission assembly of an automobile and an automobile with the automatic transmission assembly. Background technique

[0002] In the field of automotive powertrain component manufacturing technology, the transmission occupies a very important position. The transmission is usually connected with the vehicle engine to transmit the power from the engine. At present, automatic transmissions have been applied to more and more cars, among which continuously variable transmissions (CVT) occupy a certain share in the market because of their excellent performance. CVTs are mainly used in front-engine front-wheel drive cars. However, due to the limited height space below the front floor and the minimum ground clearance requirement, the center distance of the CVT speed change mechanism is limited, so the center distance of the CVT speed change mechanism cannot be chan...
