Abstract

The invention belongs to the technical field of a transmission system, and relates to a traction transmission device, in particular to a double-cone hydraulic tightening type traction transmission device, which comprises an outer friction wheel, an inner friction wheel, one or more than one group of speed control mechanisms and a hydraulic pressing mechanism. When pressure in a hydraulic oil chamber is increased, an inner conical roller and an outer conical roller are respectively matched with a rotating shaft in a sliding way and move inwards along a middle axis, so that the inner friction wheel is contacted with the conical surface of the inner conical roller, and the outer friction wheel is contacted with the conical surface of the outer conical roller. The power transfer function, the stepless speed changing function and the function of loading force control via the friction pair are integrated, and the double-cone hydraulic tightening type traction transmission device has the advantages of simple and compact structure, wide transmission scope, high transmission efficiency, large-scale power transfer, flexible and convenient control and the like.

Description

technical field [0001] The invention belongs to the technical field of transmission systems, and relates to a traction transmission device, in particular to a double-cone hydraulic tightening type traction transmission device. Background technique [0002] 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 of mechanical CVT are steel belt CVT, chain CVT and friction traction CVT. Steel-belt continuously variable transmissions have been widely used in low-power vehicles, but there are fewer CVTs used in high-power vehicles. Contents of the invention [0003] The purpose of the present invention is to overcome the defects existing in the prior art, and to design a device that integrates the power transmiss...
