Abstract

The invention discloses a stepless speed change mechanism and an automobile. The stepless speed change mechanism comprises a driving wheel disc and a pressure adjusting wheel disc which are parallel to each other; at least one speed change roller is arranged between the driving wheel disc and the pressure adjusting wheel disc; the axis of the speed change roller is parallel to the driving wheel disc and points to the axis of the driving wheel disc; contact surfaces of the driving wheel disc, the pressure adjusting wheel disc and the speed change roller are provided with friction layers; the speed change roller is provided with a position adjusting device which can adjust a distance from the center of the speed change roller to the center of the driving wheel disc; and the pressure adjusting wheel disc is provided with a pressure adjusting device to adjust the pressure applied to the speed change roller by the pressure adjusting wheel disc. The stepless speed change mechanism can realize stepless speed change and improve the torque transmitting capacity.

Description

technical field [0001] The invention relates to mechanical transmission technology, in particular to a continuously variable speed change mechanism. Background technique [0002] The continuously variable transmission mechanism can realize stepless change and transmission of speed and torque. The transmission ratio of the continuously variable transmission mechanism is continuously changing. The structure of the continuously variable transmission mechanism is simpler than that of the traditional automatic transmission mechanism, and the volume is smaller. [0003] The existing continuously variable transmission mechanism uses a transmission belt and a ratchet with variable groove width for power transmission, that is, when the ratchet changes the groove width, the contact radius between the driving wheel and the driving belt on the driven wheel is correspondingly changed for speed change. The transmission belt generally adopts rubber belt, metal belts and metal chains etc. ...
