Problems solved by technology

Among them, the screw nut is fixedly connected with the shift fork, and the rotation tendency of the nut when moving on the lead screw is also limited by the shift fork, which is also likely to cause the vibration of the shift fork, resulting in loud noise and unstable shifting

Abstract

The invention relates to a dynamic coupling control device. The dynamic coupling control device comprises is used for selectively putting through or breaking the transmission connection of a driving mechanism and a transmission system of a vehicle and comprises an actuating motor, an actuating gear, a supporting seat, an actuating piece and a stop piece; the actuating gear comprises a barrel-shaped shaft part and a gear part in transmission connection with the actuating motor; the shaft part is rotationally supported on the supporting seat, is fixed relative to the supporting seat in the axialdirection and can rotate relative to the supporting seat; the shaft part is sleeved with the actuating piece and is in screw-thread fitting with the actuating piece; the actuating piece and the supporting seat are located on the two opposite sides in the radial direction of the shaft part; and the stop piece is connected fixedly with the supporting seat and is connected with the actuating piece,so that the rotation movement of the actuating piece relative to the supporting seat is stopped. The dynamic coupling control device is simple in structure, high in control precision and high in reliability.

Description

technical field [0001] The invention relates to the technical field of vehicles. Specifically, the present invention relates to a power coupling control device. Background technique [0002] In a vehicle, it is usually necessary to set some power coupling control devices between the driving mechanism such as the internal combustion engine or the electric motor and the transmission system. These power coupling control devices are driven by motors or manually, and actuate mechanisms such as synchronizers to selectively engage or disengage different transmission paths, so as to achieve gear shifting and other purposes. Most current vehicles, especially new energy vehicles, use dedicated motors to drive such power coupling control devices, but the actuating mechanism mostly uses traditional fork-type mechanisms. [0003] CN 106838300 A discloses an automatic synchronous gear shifting system and an electric vehicle. Among them, the shift motor directly drives the lead screw, a...
