Abstract

A continuously variable transmission with high function security is provided with a revolving speed signal generation device, a resolving speed signal generation sensor, a conical plate position signal generation device and a conical plate position signal generation sensor. A signal device is arranged between a lubricating oil pump and an inlet of the lubricating oil pump and is used for detecting whether a filter screen is blocked or not. Moreover, a component is used for judging whether the oil pump fails or not according to a temperature difference value of a temperature sensor. In a whole system, common cause failure on selection and arrangement of the sensors can be avoided to the greatest extent, and the safety and the reliability of the continuously variable transmission are improved.

Description

Technical field: [0001] The invention relates to the field of transmissions, in particular to a continuously variable transmission with high functional safety, which is mainly used in the fields of automobiles, construction machinery, power machinery and the like. Background technique: [0002] Cone-disc CVT is widely used in transportation, construction machinery, agricultural machinery, power generation equipment and other industrial fields. Transmission of power and movement. The adjustment of the gear ratio and the lubrication and cooling of the system by changing the axial position of the conical disk are the key functions of this type of continuously variable transmission. [0003] The application field of the continuously variable transmission, especially the automotive field, has higher requirements on the system safety. The following describes how to improve the reliability of the continuously variable transmission from the aspects of common cause failure, functio...
