The invention discloses an automobile electronic control two-wheel and four-wheel drive switching clutch. The automobile electronic control two-wheel and four-wheel drive switching clutch comprises a half-long shaft, a mechanical wheel and a shift sleeve; and the shift sleeve is shifted by an electronic control shift fork assembly which comprises a machine shell, a motor, a worm, a duplicate gear, a first gear, a torsional spring and a second gear, wherein the motor, the worm, the duplicate gear, the first gear, the torsional spring and the second gear are installed in the machine shell. According to the automobile electronic control two-wheel and four-wheel drive switching clutch, the worm is driven by the motor to rotate and drives the duplicate gear to drive the first gear which drives the second gear through the torsional spring, and the second gear drives a rack which drives a shift fork; the shift fork sleeve is shifted by the shift fork to slide, so that the two states that the half-long shaft is sleeved with the shift fork sleeve, or the half-long shaft and the mechanical wheel are sleeved with the shift fork sleeve are achieved, thus the two-wheel and four-wheel drive states are switched, and the structure is simple; through the torsional spring, the energy storage function of the device is achieved, the half-long shaft or the mechanical wheel is prevented from breaking up by the shift fork sleeve, and the more reliable effect is achieved; and when the two-wheel drive state is switched, the mechanical wheel stops rotating, namely a front-driving axle main reducer transmitted with the mechanical wheel stops working, and noise and oil consumption of an automobile are reduced.
