State, Japan etc. have also successively carried out the research of hub drive system.China's In-wheel motor driving technical research starting than it is external compared with
Evening, but my army notices the potential advantages of hub motor very early, all arranges special topic in continuous several five-year plans and gives emphasis branch
It holds.By early-stage study, China's wheel hub (wheel side) motor-drive technique has had been provided with certain Research foundation, but advanced with foreign countries
For level compared to still there is certain gap, technical solution is one of them.In the confined space inside wheel rim, integrated motor, speed change/
Deceleration mechanism, brake, at the same time, it must also be considered that heat dissipation and lubrication and the suspension connection between electric driving wheel and car body, wheel
The selection of hub motor driven overall plan directly determines the subsequent implementation of each subsystem component, also affects the property of system
Energy, reliability and manufacturing cost.

From including a sun gear, a gear ring, a planet carrier and several planetary gears；Sun gear, gear ring and planet carrier have one
Common fixation rotary shaft, planetary gear are supported in the planetary gear shaft for being fixed on planet carrier, and sun gear external toothing, while with
Gear ring internal messing；Planetary gear set includes at least three planetary gears；When planet row operating, planetary gear of the empty set on planet carrier exists
It revolves together around sun gear while around planetary gear shaft rotation also as planet carrier；
The driving motor (1) provides driving force, turns by planetary gear speed reducing mechanism (2) and planet speed change mechanism (3) driving wheel
It is dynamic；The brake (21) provides brake force, brakes wheel rim (22)；
The brake (21) is dry friction disk brake, in the no-clutch course of work, under a certain gear, and driving electricity
Machine (1) is in motoring condition, by planetary gear speed reducing mechanism (2) and planet speed change mechanism (3), imparts power to wheel rim (22),
Drive vehicle wheel rotation；
The speed-change process of the device are as follows: the hydraulic cylinder (14a) of hydraulic gear-shifting mechanism (6) utilizes hydraulic drive push rod (14b), push rod
(14b) pushes conjunction gear set (15) to be axially moveable, when the conjunction gear set (15) is moved to the left, left tooth set (15a) and first
When outer gear ring (13a) combines, third gear ring (19) is braked, and planet speed change mechanism (3) is in one grade, realizes vehicle low-grade location row
It sails；When the conjunction gear set (15) moves right, and left tooth set (15a) and the second outer gear ring (11a) are combined, the second common planetary
The third sun gear (16) of row (5) is connect with third gear ring (19), and the second common planetary is arranged (5) and integrally turned round, planetary speed-changing machine
Structure (3) is in two grades, realizes vehicle high tap position traveling；When the conjunction gear set (15) is in an intermediate position, left tooth set (15a)
Connectionless, planet speed change mechanism (3) is in neutral gear, unpowered output；Third planet carrier (17) and support shaft (20) and wheel rim
(22) it connects, output power, drives vehicle wheel rotation.
