A dual-spherical disc type stepless transmission comprises a box body, a power input shaft, a speed-reducing input shaft and a speed-reducing output shaft; the power input shaft is connected with the speed-reducing input shaft through a reverse-neutral gear shifting device; the speed-reducing input shaft is connected with the speed-reducing output shaft through a dual-spherical friction transmission stepless speed change device; the dual-spherical friction transmission stepless speed change device comprises two friction discs, two friction transmission turning wheels and a swing driving device used for driving the two friction transmission turning wheels to swing synchronously; the two friction discs are fixedly connected to the speed-reducing input shaft and the speed-reducing output shaft respectively; the two friction transmission turning wheels are located between the two friction discs; each friction disc is provided with an arc-shaped annular groove; each friction transmission turning wheel is provided with a spherical surface; the sphere center of each spherical surface is overlapped with the axis of a corresponding swing shaft, and the spherical surfaces are in contact and fit with the inner walls of the arc-shaped annular grooves of the two friction discs at the same time within the swing range of the friction transmission turning wheels. The dual-spherical disc type stepless transmission is simple and compact in structure, long in service life, large in speed change range, good in speed change stability and easy to apply and popularize.
Description
technical field [0001] The invention relates to the technical field of transmissions, in particular to a double spherical disc type continuously variable transmission. Background technique [0002] As my country's investment in infrastructure and key construction projects has increased, the demand for automobiles in the market has risen sharply, and the demand for automobile gearboxes has also increased. In recent years, automobile transmissions are developing in the direction of multi-polarization and light weight. At present, our country has developed a lot of computer design software for the design of the gearbox, from the matching of the whole machine to the interference judgment of the components and the fuzzy comprehensive judgment of the whole scheme, until the check of gears and clutches, etc., but most of them have not formed industrialized design and manufacturing. , so further enhancement is needed. With the continuous advancement of technology and the continuou...
