Abstract

A novel stepless speed change device comprises an input shaft and an output shaft which are arranged in the left-right direction, and the input shaft is located on the left side of the output shaft. The novel stepless speed change device is characterized in that the left side and right side of the input shaft are each provided with a left automatic pressurizing mechanism and a right automatic pressurizing mechanism; a roller position radial slip output mechanisms is arranged on each of the front side and the rear side of the input shaft between the left automatic pressurizing mechanism and the right automatic pressurizing mechanism in a transmission manner; and the power output ends of the two roller position radial slip output mechanisms are in transmission connection with the output shaft. A first pressurizing disc and a third pressurizing disc are limited by a first locking nut and a second locking nut in the novel stepless speed change device, and positive pressure between a friction disc and a roller is sealed on the input shaft; bearings at the two ends of the input shaft are exempted from positive pressure, and therefore the stepless speed change device is suitable for high-speed rotation; the first friction disc and a second friction disc are rotated oppositely through a reversing mechanism, and therefore the roller can be driven by the two friction discs simultaneously; the transmission torque is large, and the transmission efficiency is high; and the speed change performance is good.

Description

technical field [0001] The invention belongs to the technical field of mechanical variable speed transmission, and in particular relates to a novel continuously variable transmission device. Background technique [0002] Existing continuously variable transmission (continuously variable transmission) uses two transmission wheels whose diameter can be changed, and a transmission belt is put in the middle for transmission. The principle of stepless speed change is to wind both ends of the transmission belt on a tapered pulley, and the outer diameter of the pulley can be changed steplessly by the oil pressure. It also has a continuously variable transmission that changes two transmission wheels whose diameter can be changed into two non-concentric friction discs. .The transmission wheels and friction discs of these two kinds of speed change devices are fixed on the gearbox casing when they are working, and the gearbox casing is subjected to a large force. Contents of the inv...
