Example Embodiment

[0030] Example 1

[0031] Figure 4 It is a structural schematic diagram of Embodiment 1 of the present invention applied to a vehicle. The structure and principle of Embodiment 1 are as follows:

[0032] The stator and coil windings 3-5 are fixed on the fixed shaft 3-11 through the stator support frame 3-6 and the damping mechanism by bolts, ensuring that the stator part remains stationary; the rotor 3-3 and the rotor ring gear 3-14 The damping element 5-2 is bolted together, and the rotor ring gear 3-14 serves as the support frame of the rotor 3-3 to ensure the normal operation of the rotor 3-3; the planetary reduction mechanism includes two stages, and the main structure includes the sun gear, Planetary gear, ring gear, planet carrier, the first stage is the sun gear 3-13 fixed, ring gear 3-16 input, planet carrier 3-18 output, when the motor works, the rotor 3-3 rotates to drive the rotor ring gear 3-14 Rotation, which drives the planetary gear 3-15 to rotate, and then transm...

Example Embodiment

[0039] Example 2

[0040] The specific structure of Example 2 is as follows Figure 5 Shown. The difference from Embodiment 1 is that the braking mechanism no longer brakes the planet carrier 3-19, but brakes the rotor ring gear 3-14, and other structures and components are basically unchanged. The specific structure and working principle are as follows:

[0041] The brake disc of the brake is selected as the disc structure of the rotor ring gear 3-14. The brake caliper 6-2 is connected to the stator support frame 3-6 by bolts and nuts. When the wheel needs to be braked, the brake caliper 6-2 The disc structure 5-1 of the rotor ring gear is braked, so that the rotor 3-3 stops rotating and the vehicle stops moving forward. Compared with Embodiment 1, this design brakes the power source rotor 3-3, thereby greatly reducing the force required for braking, reducing the braking burden of the brake, and reducing the heat generated by the brake. , To ensure the braking efficiency of the...

Abstract

The invention discloses an integrated external rotor electric wheel integrated structure and an assembly method. The integrated external rotor electric wheel integrated structure comprises a hub motor, decelerating mechanisms, a brake, a damping mechanism, a cooling mechanism, a rim and the like. The decelerating mechanisms comprise a first-level decelerating mechanism and a second-level decelerating mechanism, a rotor of the hub motor and a gear ring of the first-level decelerating mechanism are designed as an integrated structure, and a planetary frame of the first-level decelerating mechanism and a sun wheel of the second-level decelerating mechanism are designed as an integrated structure. Power is input by the rotor of the hub motor and output to wheels through the gear ring and the planetary frame of the first-level decelerating mechanism and the solar wheel and a planetary frame of the second-level decelerating mechanism to drive a vehicle to operate. Meanwhile, a brake disc ofthe brake and the planetary frame of the second-level decelerating mechanism are designed as an integrated structure, the brake disc of the brake rotates accordingly, and a brake caliper is mounted ona shell. The cooling mechanism adopts a mode of combining splash cooling and oil passage cooling to complete the overall cooling of the motor, the decelerating mechanisms, the brake and the like. Thesystem can be widely used in various wheels using different manufacturers/models, and has high universality.

Description

technical field [0001] The invention relates to a pure electric drive power transmission system of an electric vehicle, in particular to a method for integrating and assembling an integrated outer rotor electric wheel. technical background [0002] As one of the key technologies of the next generation of "pure electric drive" electric vehicles, in-wheel motor drive electric vehicles have been highly valued by the industry due to their obvious technical advantages in vehicle general layout structure, chassis active control and control convenience. The in-wheel motor drive system is significantly different from the traditional centralized motor drive system for vehicles. The in-wheel motor drive system needs to highly integrate in-wheel motors, brakes and other connecting components and arrange them reasonably in narrow wheels. Therefore, due to structural and space constraints, the design of the electric wheel drive system must not only consider the requirements of vehicle dr...
