Abstract

The invention provides a single-gearbox hybrid power coupled axle based on a single planetary line. According to the axle, a hybrid power assembly is conveniently arranged, kinds of hybrid power products are enriched, and the axle is short in transmission chain, adjustable in speed ratio and high in efficiency. The axle comprises an engine, a first motor, a gearbox, a differential mechanism, a second motor and a planetary line gear structure, the gearbox and the differential mechanism are integrated into an integral axle, the planetary line gear structure comprises a sun gear, a planetary carrier and a gear ring, a center shaft of the planetary carrier penetrates a center input hollow shaft of the sun gear and directly or indirectly connected with the output end of the engine, an output shaft of the first motor is the center input hollow shaft, a plurality of planetary gears are circularly distributed on the planetary carrier, the radial inner side of each planetary gear is engaged with the sun gear, the radial outer side of each planetary gear is engaged with the inner gear ring of the gear ring, and an output shaft of the gear ring is engaged with a main reduction gear of the differential mechanism through the gear structure.

Description

technical field [0001] The invention relates to the technical field of coupling bridge structures, in particular to a single-gearbox hybrid coupling bridge based on a single planetary row. Background technique [0002] The existing coupling bridge structure is a pure electric structure, and the existing coupling bridge structure cannot be applied to a hybrid structure. Contents of the invention [0003] In view of the above problems, the present invention provides a single-gearbox hybrid coupling bridge based on a single planetary row, which makes the layout of the hybrid assembly convenient, expands the types of hybrid products, and has a short transmission chain and adjustable speed ratio, high efficiency. [0004] A single-gearbox hybrid coupling bridge based on a single planetary row, characterized in that it includes an engine, a first motor, a gearbox, a differential, a second motor, and a planetary gear structure, the gearbox and the The differential is integrated...
