Document Type and Number:
WIPO Patent Application WO/2023/029368
Kind Code:
A1
Abstract:
A power take-off transmission device (100), comprising: an electric motor (110) comprising an electric motor output end (111); a hydraulic pump (120) comprising a pump input end (121); and a mounting bracket (130) having a mounting seam allowance (1301), wherein the mounting seam allowance (1301) penetrates the mounting bracket (130) in the axial direction, and the electric motor output end (111) and the pump input end (121) are connected to each other by means of the mounting seam allowance (1301). By means of the power take-off transmission device (100), the electric motor output end (111) and/or the pump input end (121) is radially limited by means of the mounting seam allowance (1301), so as to ensure that the electric motor output end (111) and the pump input end (121) are coaxially mounted in the axial direction, thereby avoiding the occurrence of vibration, abnormal sound and oil leakage problems, and ensuring the reliability of the power take-off transmission device.
