Abstract

The invention provides a stepless speed changer and a vehicle provided with the stepless speed changer. The stepless speed changer comprises a transmission component, an actuator, first magnetic components, second magnetic components and a PLC; the transmission component comprises a driving wheel group, a driven wheel group and a transmission belt; the driving wheel group comprises a first driving disc and a first driven disc; the driven wheel group comprises a second driving disc and a second driven disc; the actuator is used for driving the first driving disc to move in the direction close to or far from the first driven disc and is also used for driving the second driving disc to move in the direction close to or far from the second driven disc; the first magnetic components are arranged on the actuator; the second magnetic components can be matched with the first magnetic components to drive the actuator to drive the first driving disc and the second driving disc to move; at least one of the first magnetic components and the second magnetic components is a first electromagnetic coil; and the PLC is connected with the first electromagnetic coils. The stepless speed changer is high in safety.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a continuously variable transmission and a vehicle with the continuously variable transmission. Background technique [0002] In the related technology, the continuously variable transmission controls the axial movement of the driving disc of the driving wheel group and the driven wheel group through the hydraulic system, changes the meshing working radius between the driving disc, the driven disc cone surface and the transmission belt, and then changes the transmission ratio to realize the speed change. . However, there is an inevitable leakage in the hydraulic transmission process, which will have adverse effects on occasions with strict transmission ratio requirements (such as gear meshing transmission); the hydraulic transmission process is sensitive to changes in oil temperature, which will affect the stability of the transmission. For automotive transmissions, the oil tem...
