The invention discloses a two-gear-shifting integrated electric wheel drive unit for vehicles, and an automobile including the same. The drive unit includes a driving motor and wheel rims; the wheel rims are fixedly connected to a wheel rim connecting flange; the wheel rim connecting flange is sleeved by a rear shell; the input end of a first stage planetary deceleration mechanism in the rear shell is connected to the output shaft of the driving motor; the output end of the first stage planetary deceleration mechanism is connected to the input end of a first gear transmission pair; the outputend of the first gear transmission pair is connected to the output end of a second gear transmission pair; the output end of the second gear transmission pair sleeves on the wheel rim connecting flange; and an electromagnetic clutch is arranged between the first gear transmission pair and the second gear transmission pair and connected to the wheel rim connecting flange through splines. The driveunit has functions of driving, clutching, shifting, braking and supporting and integrates all parts in a wheel, so that the drive unit is compact in structure, and therefore, the axial size of a wheelhub driving device can be effectively decreased, and the mass of the wheel hub driving device can be reduced.
Description
technical field [0001] The invention relates to an electric wheel drive unit, which belongs to the technical field of drive unit components of a hybrid electric vehicle, in particular to an electric wheel drive unit integrated with two gears for a vehicle and an automobile containing the drive unit. Background technique [0002] As a new type of clean energy, electric energy will become an inevitable trend of future energy development, and electric vehicles will inevitably replace traditional fuel vehicles as the mode of transportation in the new era. Compared with traditional cars, electric-wheeled cars with distributed drive structure can save complex and heavy transmission systems such as gearboxes, drive shafts, and differentials, significantly reduce the weight of the vehicle and have a more balanced distribution, high transmission efficiency, and save energy. At the same time, it is convenient to realize the design of low-floor vehicles, which is convenient for passeng...
