Embodiment Construction

[0083] The mechanism of the present invention only provides the realization method of the key mechanism theory, and further design is needed for the practical specific mechanical structure.

[0084] According to the needs of the speed regulation range in practice, the secondary speed regulation mechanism and the reversing mechanism can be omitted. At this time, if it is necessary to change the steering of the output shaft of the transmission, it can be realized by adjusting the direction of the steel ball bracket. The shifting range of the transmission is also determined by the determined shape of the crankshaft. However, in the initial design, it is still possible to design a suitable crankshaft according to the actual usage.

[0085] When the simple design is adopted, the only thing that needs to be controlled is the rotation of the helical disc. Since the control part is close to the outside of the reducer housing, it is also very convenient to design the control method. ...

Abstract

Purpose of the invention is to solve a series of problems: large prestress, high thermal value, short service life, low efficiency, and rigorous requirement for materials brought by friction of general stepless gear. The disclosed mechanism realizes transmission by structure of steel balls and wedge slot. Speed changing procedure is not dependent on means of speed adjustment in liquid, friction, and electrical power. In the invention, input axis and output axis are coaxial. Rotating external rotatable disc unit can make speed changer obtain variable transmission ratio. In addition, the invention sets up controller for shift zone. Using the controller can obtain continuously variable shift zone in suitable range. No matter input rotation speed is in positive or negative, the intermediary mechanism outputs rotation in same direction. Unit for switching rotation direction provided by the invention is as an option. Pin type interposer is adopted in the control scheme.

Description

(1) Technical field [0001] The invention belongs to the field of mechanical transmission and continuously variable transmission technology. (2) Background technology [0002] In the automobile industry, "continuously variable transmission technology" is one of the key technologies of automobiles and the research and development direction of automobile technology. Since the "Ninth Five-Year Plan" period, the research and development of continuously variable automatic transmissions for cars have been included in the country's major scientific and technological research plan to track the development of world technology and develop cars suitable for my country's national conditions. [0003] CVT transmission mostly utilizes friction transmission to achieve speed change, and can be divided into mechanical, hydraulic, hydraulic, pneumatic and electric types. A mechanical continuously variable transmission usually consists of three parts: a transmission mechanism, a pressurizing d...
