The invention discloses a rocker-type
continuously variable transmission, which relates to a mechanical
continuously variable transmission for a vehicle. The rocker-type
continuously variable transmission is structurally characterized in that sliders I, slide ways I, rockers, sliders II, slide ways II, connecting rods, racks, straight gears and one-way bearings are symmetrically and sequentially mounted on two sides of a cylindrical
cam, the sliders I are mounted on the corresponding slide ways I, a roller on one side of each slider I is mounted in a slide way of the cylindrical
cam, a roller on the other side of each slider I is embedded into a slide groove of one rocker, the sliders II are mounted on the corresponding slide ways II, a roller on one side of each slider II is embedded into a slide groove of the other rocker, the other side of each slider II is movably connected with the bottom of each connecting rod, the connecting rods are connected with the corresponding racks through rack supporting grooves, the racks are engaged with the straight gears, the one-way bearings are mounted in the straight gears, a gear shaft is mounted between the two one-way bearings, a
bevel gear I is mounted in the middle of the gear shaft and engaged with a
bevel gear II, a
power output shaft is mounted on the
bevel gear II, the front ends of the two opposite rockers are connected with each other by a rocker shaft, and a power input shaft is mounted at the bottom of the cylindrical
cam.
