Problems solved by technology

[0002] At present, in-wheel motors are widely used in electric vehicles. In-wheel motors generally include AC motors, reluctance switch motors, DC motors, and permanent magnet brushless motors. At present, the direct-drive outer rotor has insufficient starting torque and jitters. Due to the impact of size and space, the structure is relatively complicated, and the installation of the whole vehicle is inconvenient. The installation of the motor, wheel hub, rim, brake, suspension, and shock absorption of the electric vehicle is unreasonable, taking up a lot of space, resulting in the structure of the hub motor of the electric vehicle. Not compact, low overall power density

Abstract

The invention discloses a hub assembly of a disc type variable-speed motor of an electric vehicle, belonging to the technical field of hub motors. The hub assembly is mounted between a rim and a suspension cleat, and comprises a stator shaft which is fixedly mounted on the suspension cleat of the electric vehicle; a stator assembly is fixed on the stator shaft; the periphery of the stator assembly is surrounded by an inner rotor assembly; the periphery of the inner rotor assembly is provided with an outer rotor assembly; the outer rotor assembly is fixedly mounted on the rim; and a variable-speed device is arranged between the inner rotor assembly and the outer rotor assembly, and mainly comprises an inner gear ring, a sun wheel and a planetary wheel. The hub assembly disclosed by the invention makes full use of the effective space, has a simple and compact structure, realizes high entire power density and high comprehensive efficiency, and is convenient to mount and widely applied to the electric vehicles.

Description

technical field [0001] The invention relates to the technical field of hub motors, in particular to a hub assembly of a disc-type variable speed motor for electric vehicles. Background technique [0002] At present, in-wheel motors are widely used in electric vehicles. In-wheel motors generally include AC motors, reluctance switch motors, DC motors, and permanent magnet brushless motors. At present, the direct-drive outer rotor has insufficient starting torque and jitters. Due to the impact of size and space, the structure is relatively complicated, and the installation of the whole vehicle is inconvenient. The installation of the motor, wheel hub, rim, brake, suspension, and shock absorption of the electric vehicle is unreasonable, taking up a lot of space, resulting in the structure of the hub motor of the electric vehicle. Not compact, low overall power density. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide...
