Problems solved by technology

[0005] The technical solutions disclosed above have the following problems: the power density is low, and it is difficult to integrate with the suspension, because the larger in-wheel motor with a reducer occupies the space where the suspension swing arm is connected to the hub unit; the failure safety is low , if the in-wheel motor fails, the wheel will lose controllable driving force, which may cause safety hazards

Embodiment Construction

[0047] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The drawings show preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0048] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustr...

Abstract

A wheel hub driving device with planetary motors comprises the planetary motors and planetary mechanisms. Each planetary motor comprises a gear ring stator and a plurality of planetary rotors radially arranged on the inner side of the gear ring stator; each planetary mechanism is used for matching rotate speed and torque of each planetary motor and a wheel hub and comprises a planetary carrier, a gear ring and a plurality of planetary gears; the planetary gears are radially arranged on the inner side of each gear ring; the planetary gears are meshed with the corresponding gear rings so as to enable the planetary gears to roll along the inner peripheries of the gear rings; the planetary gears are respectively in one-to-one correspondence to the planetary rotors, and the planetary gears are respectively coaxially connected with the planetary rotors; the planetary gears are respectively rotatably connected with the planetary carriers through rotating shafts so as to enable the planetary carriers to rotate with the planetary gears relate to the gear rings. The wheel hub driving device is higher in power density, reliability and fault safety. The invention further provides a wheel power system adopting the wheel hub driving device.

Description

【Technical Field】 [0001] The invention relates to a wheel hub driving device, in particular to a wheel hub driving device with a planetary motor and a wheel power system adopting the wheel hub driving device. 【Background technique】 [0002] Independent wheel drive is an ancient and advanced driving method. It has the following significant advantages: First, the driving force and braking force of the wheels can be independently adjusted and coordinated according to the needs of the vehicle, and the vehicle has excellent dynamic characteristics; Second, the overall layout of the vehicle is extremely simplified and flexible, and the space inside the vehicle is maximized. Its shortcomings are mainly to increase the non-suspension mass, reduce the vehicle grounding safety and smoothness at low speeds, but improve the vehicle smoothness at high speeds. Studies have shown that as long as the increased non-suspension mass is small and the existing suspension is adjusted accordingly, the...
