Embodiment Construction

[0014] figure 1 It is a sectional view of the hub drive device 100 of the present invention. Such as figure 1 As shown, the hub driving device 100 includes a motor composed of a stator 1051 and a rotor 1052 , wherein the stator 1051 is fixed on the housing 1041 , and the rotor 1052 is fixed on the rotor bracket 1053 . The rotor bracket 1053 is respectively supported on the support plate 1042 and the housing cover 1043 through the rotor bearing 1054 . The housing cover 1043 is fixed on the housing 1041 . When the motor is running, the rotor 1052 together with the rotor bracket 1053 rotates relative to the support plate 1042 / housing cover 1043 .

[0015] The hub driving device 100 includes two reduction stages, namely, the first reduction stage—the first stage planetary gear set 1060 and the second reduction stage—the second stage planetary gear set 1020 . The sun gear of the first-stage planetary gear set 1060 is connected to the rotor support 1053 in a torque-resistant man...

Abstract

The invention relates to a hub drive device for a vehicle and a hub drive vehicle. The hub drive device comprises a motor, a first retarding stage, a second retarding stage and a hub. The torque of the motor is transmitted to the hub through the first retarding stage and the second retarding stage, wherein the first retarding stage and the second retarding stage are designed into planetary gear transmission mechanisms with the same rotating axis, and the torque output end of the first retarding stage and the torque input end of the second retarding stage are in anti-torque connection. A rotorof the motor also has the same rotating axis as that of the first retarding stage and that of the second retarding stage, and the rotor is in transmission connection with the first retarding stage. The hub has the same rotating axis as that of the second retarding stage, that of the first retarding stage and that of the rotor, and the hub penetrates through the second retarding stage, the first retarding stage and the rotor in sequence. According to the hub drive device and the hub drive vehicle,a large transmission ratio can be obtained through a short transmission chain, energy loss is reduced, and the whole compactness and the stability of the hub drive device are improved.

Description

technical field [0001] The invention relates to the field of hub drives. In particular, the present invention relates to a hub drive for a vehicle and a vehicle comprising such a hub drive. Background technique [0002] With the depletion of fossil energy and the aggravation of air pollution, new energy vehicles are getting more and more attention from the society. Current new energy vehicles mostly use a central drive motor, clutch, 2-3 gear transmission and traditional drive axles to drive the wheels. Such a drive system includes many components, and the transmission chain is very long, so the energy loss is relatively large. All these components and the differential in the traditional drive axle have a great influence on the layout of the vehicle. For example, in a bus, bosses need to be set above these components, which affects the space layout inside the vehicle. [0003] The emerging wheel hub drive technology can solve the above problems to a certain extent. Howev...
