Abstract

The invention provides an electromagnetic and intelligent coupler which is of a rotating body assembly. One end of the electromagnetic and intelligent coupler is provided with a driving shaft (1), and the other end of the electromagnetic and intelligent coupler is provided with an output shaft (10); the external surface of the driven shaft is provided with a shell (17) with an inner cavity; the shoulder of the shell (17) is provided with an annular groove (16); an electromagnetic coil (3) is arranged in the annular groove (16) and is in clearance fit with the annular groove (16); a central shaft (4) is positioned in a key slot of a rotary driving shaft (1), and the upper part of the central shaft (4) is provided with a thrust bearing driving disc (7) and a clutch pressure plate (13). The electromagnetic and intelligent coupler is characterized in that the driving shaft (1) is in press-fitting fit with the shell (17) by virtue of a connecting ring (15). By virtue of press-fitting fit among the driving shaft, connecting ring and shell of the electromagnetic and intelligent coupler, the processing process is relatively simple, welding deformation is avoided, the manufacturing cost is greatly lowered and the application range is enlarged.

Description

technical field [0001] The invention relates to a final reducer assembly in auto parts, in particular to an electromagnetic intelligent coupler for front and rear axles, gearboxes and transfer case transmission mechanisms. Background technique [0002] Four-wheel drive means that the vehicle maintains four-wheel drive throughout the driving process, and the engine output torque is distributed to the front and rear wheels in a fixed ratio. The main products of the four-wheel drive system include: time-sharing system, full-time system, intelligent system and synchronizer. The electromagnetic smart coupler is one of the intelligent four-wheel drive systems. It is an interactive torque management solution for converting the engine front-mounted transverse front-wheel drive to four-wheel drive. It can be installed on the front and rear axles of the vehicle, transfer case, The gearbox is controlled by the electronic control unit ECU. [0003] When the electromagnetic smart couple...
