Problems solved by technology

However, when the tire is damaged or old and needs to be replaced, if the existing wheel is used, it is difficult to disassemble the wheel hub together with the tire conveniently and quickly due to the motor and the transmission system installed on the wheel. Solving the above problems has become a top priority

Embodiment Construction

[0033] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0034] Such as figure 1 and image 3 As shown, a centrally driven electric drive system assembly mainly includes a rotary output component 1 and a transmission shaft 2 pierced on the rotary output component 1, and a power system and a transmission system are installed on the transmission shaft 2. The power system and the speed change system are respectively located on both sides of the rotating output member 1, and the power system transmits power to the speed changing system through the transmission shaft 2, and then the speed changing system drives the rotating output member 1 to output power.

[0035] Through the newly designed central drive structure, it combines the advantages of the hub motor and the side-mounted structure, and makes up for the shortcomings of the hub motor and the side-mounted structure. It is especially suitable for two-wheeled vehic...

Abstract

The invention discloses a combined wheel for a central drive type electric drive system assembly, which comprises a hub bracket, a hub and a tire which are coaxially and sequentially arranged from inside to outside, the hub bracket is used for inputting power and installing the hub, the hub is of a hollow structure, the hub is detachably installed on the hub bracket, and the tire is sleeved on thehub. By the adoption of the technical scheme, a brand-new combined structure is utilized, the structural strength is high, reliability is good, the hub can be easily disassembled from the hub support, a motor and a speed change system do not need to be disassembled no matter whether the hub is disassembled or assembled, and therefore quick tire replacement can be achieved, and the maintenance convenience of the central drive type electric drive system assembly is improved.

Description

technical field [0001] The invention relates to a wheel, in particular to a combined wheel used in a center-driven electric drive system assembly. Background technique [0002] With the increasingly stringent environmental protection regulations, it is a general trend that new energy vehicles represented by pure electric vehicles, two-wheelers, and tricycles will replace traditional fuel vehicles. Existing two-wheeled electric vehicles generally adopt hub motors and motor side-mounted structures. [0003] The hub motor is directly driven by a low-speed DC motor, which not only has relatively low efficiency and high heat generation, but also breaks the original balance of the wheel structure due to the large size and heavy weight of the motor, which will have a certain impact on handling performance and safety. [0004] The side-mounted structure puts the motor and the transmission system (gearbox or reducer) on the same side of the driving wheel. Although a high-speed motor...
