A reset spring sleeves an input rotating shaft; a sleeve pipe sleeves an input rotating shaft portion through a spline, wherein the input rotating shaft portion is located in front of the reset spring; the front end of the rest spring is fixed at the rear end of the sleeve pipe; the rear end of the reset spring is fixed on the inner side of a rear end cover; a front section of the sleeve pipe is provided with an input friction part and an input pump blade; a rear section of the sleeve pipe is provided with a pressure-bearing bearing; an annular hydraulic jack or an annular hydraulic capsule sleeves the reset spring; an output friction part and an output pump blade are fixed on an output rotating shaft; a flexible friction part is clamped between the input friction part and the output friction part; the machine oil is arranged in a housing; a front end cover and the rear end cover are provided with a plurality of small holes respectively; a front cover covers on the front end cover; a rear cover covers on the rear end cover; an oil pipe which is connected out of the front cover is connected onto a cooling oil tank through an output electric regulating oil valve; the oil pipe which is connected out of the cooling oil tank is connected onto the rear cover through an input electric regulating oil valve; the machine oil in the cooling oil tank is cooled through an air cooling or water cooling mechanism.

Description

Technical field: [0001] The invention relates to a mechanical friction and hydraulic transmission integrated type continuously variable transmission device. Background technique: [0002] The stepless speed change on the existing automatic transmission automobile is divided into mechanical friction stepless speed change and hydraulic transmission stepless speed change. When the difference between the input and output speeds is small, the mechanical friction stepless transmission has a strong torque output, the difference between the input and output speeds is relatively stable, and the friction loss is small. When the difference between the input and output speeds of mechanical friction stepless transmission is large, the torque output is small, the difference between input and output speeds is unstable, the friction loss is large, and the mechanical friction stepless transmission will generate heat. The oil in the gear box is pumped into the oil cooling box, and then the o...
