Problems solved by technology

In the above literature, the pressurizing mechanism is arranged on the side of the fixed cone, which has a compact structure, but it is difficult to achieve a balance between the axial pressure required by the flexible element and the transmission efficiency, and due to the existence of the speed ratio, the working conditions of the main and driven shafts are not Symmetrical, so the pressurized cam mechanism on the fixed cone side of the main and driven shafts is not symmetrical, and should be treated differently

Abstract

The invention relates to a cam-pressed cone-plate type continuously variable transmission. The cam-pressed cone-plate type continuously variable transmission includes a driving cone-plate set arrangedon a driving shaft, a driven cone-plate set arranged on a driven shaft, an end-face cam-pressed mechanism, and a steel flexible transmission element. By setting the angle of a V-shaped groove of theend-face cam-pressed mechanism and the association relationship of related parts, the dynamic response of a system is significantly improved, the service life of the overall system is prolonged, and the system reliability is also improved.

Description

technical field [0001] The invention belongs to the field of power mechanical transmissions, and in particular relates to a cam-pressurized cone-disk continuously variable transmission. Background technique [0002] Driven by factors such as energy, environmental protection, and market competition, the automatic transmissions of traditional fuel vehicles and new energy vehicles need to be more efficient and reliable, and the cost needs to be continuously reduced. The light weight and miniaturization of automobiles and the increase in cruising range require the size of the battery pack, which also drives the structure of the transmission to be more compact. At the same time, a more compact structure and cooling, heat dissipation, etc. also need to be better balanced. [0003] In the prior art, the pressurizing mechanism is mostly set on the side of the moving cone, such as the method of using the end face cam and the hydraulic system to pressurize the moving cone of the cont...
