Abstract

The invention relates to a cylindrical gear type power dividing power system. The system comprises an engine, a driving shaft, a motor control module and a power dividing module, wherein the power dividing module comprises a cylindrical gear differential mechanism; the cylindrical gear differential mechanism comprises a first gear shaft, a transmission gear, a planet carrier, a large sun gear, a small sun gear, a short planet gear and a long planet gear; the output shaft of the engine is connected with the planet carrier; the short planet gear is installed on the planet carrier, and rotates around the small sun gear and is meshed with the long planet gear; the large sun gear is meshed with the long planet gear and is coaxially connected with the transmission gear through the first gear shaft; and the transmission gear is connected with the driving shaft and the motor control module. Compared with the prior art, the cylindrical gear type power dividing power system achieves the couplingof hybrid power completelythrough a connecting structure of the cylindrical gear, an inner gear ring structure needed by a planetary gear set is not arranged in the cylindrical gear, the industry problem of inner gear ring machining is avoided, and meanwhile the power transmission characteristic and structural arrangement are simpler and more stable.

Description

technical field [0001] The invention relates to pure electric and hybrid power systems, in particular to a spur gear type power split power system. Background technique [0002] New energy vehicle technology has developed rapidly in recent years, and the technical route is also flourishing. However, in view of the respective advantages and disadvantages of various technical routes, the constraints of technical bottlenecks, infrastructure, manufacturing costs and other factors, the application of internal combustion engines in automobiles will not disappear for a long time by virtue of their own advantages. However, due to its inability to maintain an ideal level in terms of energy consumption and emissions, traditional cars that only rely on internal combustion engine power will disappear completely. Hybrid technology well integrates the respective advantages of internal combustion engines and electric motors, which effectively improves the energy consumption and exhaust em...
