Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, a driving assembly structure 10 of the present invention includes: a motor 11 and a tire 12. The drive assembly structure 10 further includes: a mounting block 13 and a reducer 16. The motor 11 and the reducer 16 are detachably mounted on the upper end of the mounting block 13, so that the driving assembly can be conveniently detached and mounted. The tire 12 is rotatably connected to the lower end of the mounting block 13 by a drive shaft 14. The motor shaft 111 of the motor 11 is connected to the input shaft 161 of the speed reducer 16 through the mounting block 13. The transmission shaft 14 is fixed to the tire 12, and one end thereof is meshed with an output gear 162 of the speed reducer 16 through the tire 12, thereby achieving transmission of torque to transmit power to the tire 12. The housings of the motor 11 and the speed reducer 16 are formed of aluminum die-cast parts.
The motor 11 and the speed reducer 16 of the driving assembly structure 10 are non-bearing parts and only transmit torque, and the speed reducer 16 and the mounting block 13 are in split design and are convenient to disassemble and assemble. The motor 11 and the speed reducer 16 are made of aluminum die castings, so that the production period is short, the cost is low, and the weight is light.
Further, the tire 12 is connected to the propeller shaft 14 by a key 15. The motor shaft 111 is connected to the input shaft 161 through a coupling sleeve 17. The drive shaft 14 is rotatably connected to the mounting block 13 by a mounting seat 18 fixed to the mounting block 13. A rotary bearing 19 is arranged between the transmission shaft 14 and the mounting seat 18.
Two mounting feet of the motor 11 and the speed reducer 16 are directly assembled with the mounting block 13 into a whole through fastening screws, and the connection of the motor shaft 111 and the output shaft is realized through the connecting shaft sleeve 17, so that the two shafts are prevented from contacting with the mounting block 13. The tyre 12 is mounted inside the mounting block 13 and transmission is achieved by means of a transmission shaft 14. One end of the transmission shaft 14 is connected with an output gear 162 of the speed reducer 16 through a flat key or a spline, and the other end is connected with the rotating bearing 19 in the mounting seat 18. The mounting seat 18 is mounted on the mounting block 13 through a spigot. One surface of the mounting block 13 is fitted to a mounting spigot of the speed reducer 16 and fixed together by a fastening screw. Therefore, the motor 11 and the speed reducer 16 are non-bearing parts, only torque is transmitted, and the structure is more reliable.
In a specific embodiment, an electric brake 20 is disposed on a side of the speed reducer 16 away from the mounting block 13. The electric brake 20 is used to brake the tire 12. The electric brake 20 is provided with a protective cover 21 at the periphery thereof. The shield 21 is fixed to the housing of the reduction gear 16 by screws. One end of an input shaft 161 of the speed reducer 16 is connected with the motor shaft 111 through a connecting shaft sleeve 17, and the other end is directly connected with the electromagnetic brake.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
