Description

Technical Field

[0001] This utility model relates to the field of tractor traction technology, and in particular to a universal traction drive. Background Technology

[0002] Tractor traction refers to the ability of a tractor to move forward and pull implements or other machinery by generating a horizontal reaction force through the friction between the drive wheels and the ground. When a tractor is towing a rear-mounted mechanical device, it usually requires the assistance of traction equipment to facilitate steering.

[0003] However, the universal joint drive in typical traction equipment can only adjust the steering angle by 45 degrees to the left and right. This limited steering range results in low efficiency and high wear during tractor towing. Furthermore, the gearbox in typical traction equipment lacks sufficient cooling space, leading to inadequate overall heat dissipation. Therefore, how to increase the steering range of the traction device, thereby improving work efficiency and performance, and ensuring better overall heat dissipation, are crucial issues that need to be addressed in the design of universal joint drive traction devices.

[0060] The cleaning structure 4 includes a plug-in block 401, a threaded rod 402, a nut 403, and a cleaning brush 404. The plug-in block 401 is inserted into the square through slot 17. The cleaning brush 404 is fixedly connected to the side wall of the plug-in block 401. The threaded rod 402 is threadedly connected to the side wall of the plug-in block 401. The two ends of the threaded rod 402 are threadedly connected to the nuts 403. The cleaning brush 404 is respectively attached to the side walls of gearbox one 202 and gearbox two 203.

[0061] The cleaning brush 404 is attached to the side walls of gearbox 1 202 and gearbox 2 203. During the rotation of gearbox 1 202 and gearbox 2 203, the heat sink 11 is cleaned effectively, preventing dust from covering the heat sink 11 and affecting heat dissipation.

[0062] In use, all electrical components mentioned in this application are externally connected to a power supply and control switch. The mounting bracket 4 6 is mounted on the tractor, and the power input shaft 1 3 is connected to the tractor. The mechanical device to be towed is mounted on the mounting bracket 3 5 on the fixed bracket 1 101. The rear mechanical device is connected to the power input shaft 2 12. When the tractor starts and moves, the rear mechanical device can be moved by the traction device. When turning, the tractor drives the fixed bracket 2 102 to rotate through the mounting bracket 4 6. The fixed bracket 2 102 changes angle and drives the gearbox 2 203 to rotate. The tractor's power is transmitted to the gearbox 2 203 through the power input shaft 1 3, and then through the connecting shaft 1 9 and the connecting shaft 2 14. After the power is steered and changed speed through the gearbox 1 202 and the gearbox 2 203, it is transmitted to the rear mechanical device through the power input shaft 2. Power transmission is realized when it turns, and the rear mechanical device is prevented from jamming.

[0063] Since there is no obstruction between the first fixed bracket 101 and the second fixed bracket 102, the first gearbox 202 and the second gearbox 203 can turn at a large angle of 180 degrees when turning, which increases the turning range and greatly improves work efficiency and workability. Since there is no obstruction on both sides of the first gearbox 202 and the second gearbox 203, the first gearbox 202 and the second gearbox 203 have a large space for heat dissipation. The heat sinks 11 on the side walls of the first gearbox 202 and the second gearbox 203 can further assist in accelerating heat dissipation.

[0064] During the turning process, gearbox 1 202 and gearbox 2 203 will rotate relative to the opposite fixed plate 2 and fixed plate 1. The cleaning brush 404 adheres to the side wall of gearbox 1 202 and gearbox 2 203. During the turning process, gearbox 1 202 and gearbox 2 203 can effectively clean the heat sink 11 and prevent dust from covering the heat sink 11 and affecting heat dissipation. Gearbox 1 202 and gearbox 2 203 adopt a split connection, that is, they are connected by connecting sleeve 2 212 being rotatably inserted into connecting sleeve 1 211. This makes it easy to disassemble and assemble gearbox 1 202 and gearbox 2 203, thus making maintenance more convenient.
