Abstract

The invention belongs to the technical field of mechanical equipment, and particularly relates to an axial-loading biconical traction drive device. The axial-loading biconical traction drive device comprises an input shaft, a spline, a cam loading mechanism, more than one group of speed regulating mechanisms, a hydraulic compaction mechanism, an inner support shaft and an output wheel; a peripheral unit is a box body; a loading wheel is installed on the input shaft by the spline, an input wheel is installed at the right end of the output shaft by a bearing, rolling bodies are installed between the loading wheel and the input wheel, one end of the inner support shaft is connected with one end of a hydraulic rod, and the other end of the inner support shaft is vertically connected at the axle center of the inner side of double cones; and the input wheel and the input shaft are coaxial, and the left sides and the right sides of the double cones respectively prop against the input wheel and the output wheel. The axial-loading biconical traction drive device integrates the functions such as power transmission, stepless speed change, self-adaption axial force into a whole, and has the advantages that the structure is simple and compact, the transmission range is wide, the transmission efficiency is high, the power transmission is large, the control is flexible and convenient, and the like.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a traction transmission device, in particular to an axially loaded double-cone traction transmission device. Background technique [0002] In the existing technology, the continuously variable transmission can make the engine work in the best state, effectively improving the fuel economy of the car. At the same time, since the transmission realizes stepless speed change, the comfort of the vehicle is effectively improved. Currently, the CVTs mainly used in the automotive field include steel belt CVTs, chain CVTs, half-ring CVTs and full-ring CVTs. Compared with traditional stepped transmissions, CVTs are more and more concerned by researchers and consumers because of their good matching performance with vehicle power. Continuously variable transmissions have major advantages in terms of operational stability, driving comfort and economy. At present, the main forms o...
