The invention relates to a control device for vehicle when vehicle is varying speed, providing a pedal speed-varying function when the transmission gear is not feeling the break of the drive force. At the same time of controlling the speed according to the transmission ratio of the speed varying by the planet gear mechanism when the vehicle is in a low speed, and controlling the speed according to the meshed transmission mechanism when the vehicle is in the high speed; when controlling the speed according to the meshed transmission mechanism, the invention controls the engine generating torque for the internal-combustion engine when processing the automated drive and the automated clutch to drive and control the electric node air valve.

The invention relates to a mechanical speed-changing device, in particular to a variable torque type continuously variable transmission. The variable torque type continuously variable transmission realizes infinitely variable speed by changing torque of a speed-changing wheel through a speed-changing control rod. The working principle of the variable torque type continuously variable transmission is that a sliding block with a short shaft is mounted in a groove, in the radial direction, of a speed-changing wheel in the box; an eccentric shaft of a power wheel is connected with the short shaft of the sliding block through a transmission rod; a speed-changing control rod can control movement of the sliding block; the torque of the speed-changing wheel is changed through movement of the sliding block, so that the amplitude of the reciprocating rotation of the speed-changing wheel is changed and the reciprocating stroke of a rack meshed with the speed-changing wheel is changed; the reciprocating motion of the rack is transformed into homodromous rotation by a reversing wheel internally provided with an overrunning clutch; power is output through an output shaft. The radial groove of the speed-changing wheel also can lock the sliding block through isometric pin holes to form speed change with gears. The variable torque type continuously variable transmission is stable in process, large in transmission and suitable for speed change of a main shaft of an engine.

The invention relates to an alternating-current pole-changing three-speed three-phase induction motor. Two sets of three-phase windings are arranged on a stator of the induction motor; one set of three-phase stator winding has high-speed pole pairs p1 and medium-speed pole pairs p2, wherein for the high-speed pole pairs p1, the windings are in two-path star parallel connection (2Y), and for the medium-speed pole pairs p2, the windings are in triangular connection (triangle), and have 6 leading-out wire ends; the other set of three-phase stator winding has the medium-speed pole pairs p2 and low-speed pole pairs p3, wherein for the medium-speed pole pairs p2, the windings are in the triangular connection (triangle), and for the low-speed pole pairs p3, the windings are the two-path star parallel connection (2Y) and have 6 leading-out wire ends; and for the medium-speed pole pairs p2, the two sets of three-phase stator windings are in the triangular connection (triangle) and are connected in parallel, and the formed leading-out wire ends of the integral three-phase stator windings are nine. The alternating-current pole-changing three-speed three-phase induction motor has the high utilization rate and low temperature rise of winding conductors, reduces the loss, and is simple and convenient for pole-changing control.
