The invention discloses an electric hub integrated with central inflation and deflation, and relates to the technical field of hybrid electric vehicle type automobile driving unit parts. The electrichub comprises a rim and an inflation and deflation component, a motor is arranged in the rim, a spline shaft is arranged at the position of a center shaft of the rim, the spline shaft in the rim is sleeved with an electric wheel inner end cover and an electric wheel outer end cover, and the electric wheel outer end cover is located between the electric wheel inner end cover and the rim; the inflation and deflation component comprises an air pipe, one end of the air pipe is connected with an air source, the other end is connected with an air passage arranged at the outer side end part of the electric wheel outer end cover; an oil-gas seal is arranged at the end part of the outer side of the electric wheel outer end cover, the air passage on the electric wheel outer end cover is connected with the inner air passage of the oil-gas seal, the inner air passage of the oil-gas seal is connected with an air passage arranged on the rim, and the air passage on the rim is connected with a tire through a tire valve. Occupied space of the hub due to the central inflation and deflation function can be reduced, and the weight of the hub is reduced.
Description
technical field [0001] The invention relates to the technical field of drive unit components of a hybrid electric vehicle, in particular to an electric wheel hub integrated with central inflation and deflation. Background technique [0002] With the development of new energy vehicle technology, drive solutions for hybrid and electric vehicles are becoming more and more popular among car companies. Common hybrid and pure electric vehicles on the market mainly replace the engine with a motor, or add motors, batteries and other components to the car, while the form of power transmission devices such as gearboxes and drive shafts is still retained. Compared with traditional models, the entire vehicle The weight has not been reduced, but the technical complexity has been greatly improved. [0003] Improving the mileage of electric vehicles is the goal that electric vehicles have been pursuing. Reducing the overall weight of the vehicle and simplifying the transmission structure ...
