Here, the fixing member may be a screw, a rivet, etc., which are all within the protection scope of the present invention.
In this embodiment, a transition flange 2 is also fixedly disposed on a side of the first housing 3 close to the driving motor 1, and the input shaft 9 is disposed through a middle portion of the transition flange 2. One side of the input shaft 9 is provided with a connecting seat 4, the brake caliper 5 is fixed on the connecting seat 4, the connecting seat 4 comprises a first supporting arm 41 and a second supporting arm 42 which are intersected into an L shape, the first supporting arm 41 is arranged along the extending direction of the input shaft 9, and the second supporting arm 42 is perpendicular to the first supporting arm 41 and fixed on the surface of the transition flange 2.

In this embodiment, the speed reducer 8 is directly mounted in the hub 7, and the second housing 81 of the speed reducer 8 is fixedly connected to the hub 7 to transmit the rotational torque to the hub 7 through the second housing 81 of the speed reducer 8.

Therefore, the speed reducer 8 of the invention also bears the weight of the whole vehicle, and the diameter of the joint of the speed reducer 8 and the hub 7 needs to be larger as much as possible. In this embodiment, as shown in fig. 1, 3 and 4, the outer surface of the second housing 81 of the speed reducer 8 is provided with a fixing ring 83, the inner side wall of the hub 7 is provided with a fixing portion 71, and the fixing ring 83 of the speed reducer 8 is fixed to the fixing portion 71 of the hub 7 by a fixing member, whereby the outer diameter of the speed reducer 8 can be substantially approximately equal to the inner diameter at the fixing portion 71 of the hub 7 to obtain the diameter of the speed reducer 8 as large as possible. The fixing ring 83 and the second housing 81 of the speed reducer 8 may be integrally formed or separately provided. The fixing member may be a screw, a rivet, etc., which are all within the protection scope of the present invention. Further, a bearing 82 for supporting is provided inside the second housing 81 of the speed reducer 8, and the bearing 82 is provided between the second housing 81 of the speed reducer 8 and the input shaft 9. By the arrangement, the radial load bearing capacity of the speed reducer is improved. In one embodiment, a single speed reducer may carry a radial load of 350 kN. Because the power output of the invention has the characteristics of low speed and large torque and has good bearing performance, the invention is particularly suitable for vehicles used in special scenes such as heavy-duty container transfer vehicles, mining cards and the like, in addition, the invention can be applied to heavy-duty load vehicles in other scenes, and compared with the load vehicles in the prior art, the invention can improve the load capacity and the use stability.

As shown in fig. 3, a mounting ring 31 may be provided on the outer surface of the first housing 3, and the first housing 3 may be fixed to the connection bridge 10 by a plurality of fixing members penetrating the mounting ring 31. The mounting ring 31 may be integrally formed with the first housing 3 or provided separately. The fixing member may be a screw, a rivet, etc., which are all within the scope of the present invention. Therefore, the invention can realize four-wheel independent drive and realize independent and accurate control on the torque and the rotating speed of each wheel. The whole vehicle can be powered by a battery pack arranged in the middle of the vehicle to four motor controllers respectively, and the motor controllers control the output rotating speed and torque of each motor to realize differential control of left and right wheels. When the vehicle turns, the motor controller can send different rotating speeds and torque instructions to the left motor and the right motor to control the rotating speeds of the left wheel and the right wheel to be different, so that the steering torque required by the vehicle is greatly reduced, and the turning radius can be greatly reduced. As shown in fig. 2, the system can realize the driving and braking functions simultaneously and bear all the weight of the whole vehicle and the cargoes, the single shaft can realize 360-degree rotation, and the front and rear shafts can realize 50-degree steering angle when simultaneously steering. Because the four wheels are provided with the speed reducers 8 in the wheel hubs 7 independently, the total radial load of the four speed reducers 8 of the whole vehicle can reach 1400kN on the basis that the radial load of the single speed reducer 8 can reach 350kN, and the transportation bearing capacity of the whole vehicle is greatly improved. In other alternative embodiments, the drive brake integration device may be provided only on part of the drive wheels, not necessarily on all of the wheels, and is within the scope of the invention.
The working principle of the invention is as follows: the driving power is directly transmitted to an input shaft 9 of a speed reducer 8 from the driving motor 1, then is transmitted to a hub 7 through planetary gear speed reduction and torque increase of the speed reducer 8, a brake caliper 5 is mounted on a transition flange 2 through a connecting seat 4 to be fixed, a brake disc 6 is directly fixedly connected with the input shaft 9, and when braking is needed, the brake caliper 5 directly clamps the brake disc 6 to brake. The speed reduction ratio of the invention can reach 25, and when the whole vehicle speed is 25km/h, the motor rotation speed can also work in a high-efficiency zone. Because the brake calipers 5 and the brake discs 6 are arranged at the input end of the speed reducer 8, the braking moment provided by the braking mechanism can be amplified by 25 times through the speed reducer, so that the braking moment requirement on the whole vehicle braking mechanism is lower, and the hydraulic brake with lower cost and simpler structure can meet the braking requirement of the whole vehicle.
