Description

Technical Field

[0001] The utility model relates to the technical field of drive shafts, and particularly relates to a drive shaft that can be conveniently and quickly disassembled. Background Art

[0002] The drive shaft is a kind of working device of a loader, which is a device that can promote the smoothness of the loader and enable the drive wheels to rotate at different angular velocities. The drive shaft is located between the left and right drive wheels of a motor vehicle and provides power for the left and right drive wheels. The electric drive shaft includes an electric motor and left and right torque couplings. The torque generated by the motor is transmitted to the drive shaft connected to the drive wheel through the torque couplings. Each torque coupling includes a magnetic powder clutch and a planetary gear set, which are constructed such that the current flowing through the electromagnet of the clutch controls the torque transmitted through the coupling. The magnetic powder clutch can also slip, enabling the drive wheels to rotate at different angular velocities. At this time, a drive shaft that can be conveniently and quickly disassembled is required. There are still some defects in the existing drive shafts that can be conveniently and quickly disassembled. For example:

[0003] As disclosed in the patent with publication number CN219734006U, a drive shaft structure that can be quickly disassembled includes a mounting seat. One side of the mounting seat is fixedly provided with an output shaft. The inside of the mounting seat is connected with a drive shaft. A first clamping groove is opened on the side of the mounting seat away from the output shaft. One end of the drive shaft is connected with a second clamping block through a spring inside. Push plates are arranged on both sides inside the mounting seat. An installation cylinder is fixedly arranged inside the mounting seat. The drive shaft can slide and be sleeved inside the installation cylinder. The upper end of the installation cylinder is fixedly provided with an installation plate. A top plate is slidably arranged inside the installation cylinder. In the utility model, the structure is simple, the installation and disassembly are relatively convenient, the connection is tight, and it is not easy to loosen during the connection process. The length of the drive shaft can be adjusted by selecting adjustment holes at different positions according to needs, and effective sealing can also be carried out.

[0004] The above technical solution has the following problems:

[0005] The drive shaft structure that can be quickly disassembled is not provided with a quick disassembly and assembly mechanism, making it inconvenient to replace parts during use. When parts are damaged, the replacement is relatively troublesome, the maintenance cost is relatively high, it is time-consuming and laborious during maintenance, increasing the production cost and reducing the service life of the device;

[0006] In addition, the drive shaft structure that can be quickly disassembled is not provided with a multiple protection mechanism, making it unable to protect the parts during use. External vibrations are likely to affect the operation of the device or damage the parts, increasing the maintenance frequency, increasing the maintenance cost, and reducing the production efficiency.
