Electrically controlled electromechanical automatic shift system

Abstract

The invention discloses an electrically controlled electromechanical automatic shift system, which consists of a parallel shaft type speed change box, a selection and shift mechanism and an electric control unit, wherein the selection and shift mechanism comprises a first shift rack, a first shift gear, a second motor, a third motor, a second shift gear and a second shift rack; the output end of the second motor is connected with a coupler at the input end of a first speed reducer; the output end of the first speed reducer is in keyed joint with the first shift gear; the first shift gear is engaged with the first shift rack; the first shift rack is fixedly connected with a first shirt fork; a second sensor is fixedly connected with the first speed reducer; the output end of the third motor is connected with a coupler at the input end of a second speed reducer; the output end of the second speed reducer is in keyed joint with the second shift gear; the second shift gear is engaged with the second shift rack; the second shift rack is fixedly connected with a second shift fork; a third sensor is fixedly connected with the second speed reducer; and the second sensor and the wiring end of the third sensor are connected with the electric control unit through wires.

Description

technical field [0001] The invention relates to an automatic shifting system, more precisely, the invention relates to an electronically controlled electromechanical automatic shifting system applied to electric vehicles and hybrid vehicles. Background technique [0002] Environmental pollution and energy crisis have made people focus on electric vehicles and hybrid vehicles with great development potential, and their technology has also been greatly developed and improved. Electric vehicles and hybrid vehicles have different requirements for automatic shifting systems than traditional vehicles. At present, most of the automatic shifting systems are electronically controlled-hydraulic automatic shifting systems and electronically controlled-pneumatic automatic shifting systems. The gear system is useful for large or heavy vehicles with air sources, but in cars, because of the high requirements for gear shifting quality, there are relatively few applications. The electronical...
