Problems solved by technology

[0003] The direct-drive electric wheel without wheel-side reduction system directly drives the hub by the inner or outer rotor of the motor, which has poor starting and acceleration performance and slow system response
Electric wheels with wheel-side reducers are rarely used at present, and most of them are driven by one-stage reduction, and are often constrained by the performance of the motor, which cannot generate enough driving force to drive the car on specific occasions

Embodiment Construction

[0035] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0036] Such as figure 1 Shown is a structural block diagram of the present invention. It includes a motor 1, a hub 19, a primary reduction mechanism, and a secondary reduction mechanism. The motor 1 is connected to the hub 19 through a primary reduction mechanism 101 and a secondary reduction mechanism 102; the secondary reduction mechanism 102 is a planetary reduction mechanism.

[0037] The motor is mounted on the reducer housing.

[0038] Such as Figure 2 to Figure 6 Shown:

[0039] The first-stage deceleration mechanism 101 is installed on one side of the motor 1, and is connected to the motor 1 for transmission, and is driven by the motor 1 to realize the first-stage deceleration by adopting gear and ring gear meshing transmission.

[0040] The first-stage reduction mechanism 101 incl...

Abstract

The invention discloses a motor-driven hub reduction system, which comprises an electric motor (1), a hub (19), a first-level reducing mechanism (101) and a second-level reducing mechanism (102), wherein the electric motor (1), the first-level reducing mechanism (101), the second-level reducing mechanism (102) and the hub (19) are connected in sequence; and the second-level reducing mechanism (102) is a planetary reducing mechanism. The hub motor planetary reducing system has high integration, compact assembly, easy maintenance, simple structure, strong reliability, easy processing and manufacturing, and easy implementation of all-wheel drive.

Description

technical field [0001] The invention belongs to the technical field of auto parts manufacturing, in particular, the invention relates to a motor-driven wheel-side deceleration system. Background technique [0002] The wheel-hub electric vehicle is a new type of driven electric vehicle, which has two basic forms: the direct-drive electric wheel and the electric wheel with a wheel-side reducer. [0003] The direct-drive electric wheel without wheel-side reduction system directly drives the wheel hub by the inner or outer rotor of the motor, which has poor starting and acceleration performance and slow system response. Electric wheels with wheel-side reducers are rarely used at present, and most of them are driven by one-stage reduction, and are often constrained by the performance of the motor, which cannot generate enough driving force to drive the car in certain occasions. Contents of the invention [0004] The object of the present invention is to provide a motor-driven ...
