Problems solved by technology

First, the structure of the transmission system is complex, and all levels of transmission have energy loss, which makes the transmission efficiency low; second, the transmission system has many components and large volume, which requires high installation and layout space, making the space utilization rate of the vehicle low; Third, due to the complex structure of the existing wheel drive system, a large installation space is required, which makes the spring load quality high and has a great impact on the vertical, longitudinal and lateral performance of the vehicle; fourth, the existing wheel drive system The reducer and the frame, the reducer and the input shaft are fixedly connected by elastic rubber, which makes the overall structural stability poor and has a great impact on the life of the reducer; fifth, when the existing wheel drive system is removed, the tires, Brakes, brake calipers, etc. are removed, making maintenance and testing inconvenient

Embodiment Construction

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below with reference to the accompanying drawings.

[0023] Such as figure 1 As shown, the embodiment of the present invention provides a wheel side drive system, located inside the wheel hub, the wheel side drive system includes a motor 1 and a planetary reducer 2 fixedly arranged on the suspension, the outer shell of the motor 1 It is integrally connected with the outer ring gear of the planetary reducer 2 . The output shaft of the motor 1 , the output shaft of the planetary reducer 2 and the drive shaft of the wheel 4 are all located on the same axis. The driving force of the motor 1 is first transmitted to the wheels 4 through the planetary reducer 2 .

[0024] The outer casing of the motor 1 of the present invention is connected with the outer ring gear of the planetary reducer 2 as a whole, and ...

Abstract

The invention discloses a wheel rim driving system which is arranged on the inner side of a vehicle wheel hub. The wheel rim driving system comprises a motor and a planetary reducer, wherein the motor and the planetary reducer are fixedly arranged on a suspension rack, an outer casing of the motor is integrally connected with an outer gear ring of the planetary reducer, an output shaft of the motor, an output shaft of the planetary reducer, and a driving shaft of the vehicle wheels are located on a same axis, and driving force of the motor firstly passes through the planetary reducer and then is transmitted to the vehicle wheels. The wheel rim driving system is simple in structure, light in weight, wide in application and the like.

Description

technical field [0001] The invention relates to the field of electric vehicle transmission, in particular to a wheel drive system. Background technique [0002] In the context of the increasingly serious energy crisis and environmental pollution in the world, electric vehicles are more prominent in terms of energy saving and environmental protection, so countries are scrambling to study electric vehicles; while wheel drive has the characteristics of small size, high transmission efficiency, and simple structure. One of the indispensable development directions of electric vehicles. [0003] However, there are still some defects in most wheel drive systems at present. First, the structure of the transmission system is complex, and all levels of transmission have energy loss, which makes the transmission efficiency low; second, the transmission system has many components and large volume, which requires high installation and layout space, making the space utilization rate of t...
