A movable tooth type double clutch

Abstract

The invention discloses a movable-tooth type double clutch, which comprises a double-clutch body and a high-pressure oil unit; the double-clutch body includes a power input shaft, two inner rotors, two outer rotors, and movable teeth; The surrounding surfaces are all variable diameter surfaces, and the variable diameter surface is divided into multiple equal parts, and the size and direction of each equal part are equal to the variable diameter; the outer circumference of the two inner rotors is equipped with movable tooth grooves, and the movable tooth grooves The bottom communicates with the high-pressure oil inlet, the movable teeth are inserted into the corresponding movable tooth grooves one by one and the outer end is relative to the reducing surface of the corresponding outer rotor, and the high-pressure oil unit is connected with the high-pressure oil inlet. Under the control of the control unit, the invention enables the dual clutch to smoothly switch the power of the input shaft from one gear position to another through the action of high-pressure oil, and can realize the complete separation of the non-working clutch and the isolation The impact of the external load on the engine has the advantages of radial power balance, low noise, compact structure, small volume, and low manufacturing cost.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a movable tooth type double clutch. Background technique [0002] At present, the dual-clutch transmission used in automobiles has outstanding advantages such as small power loss in the transmission process, no power interruption when shifting gears, and fuel saving, and greatly improves the power, handling and smoothness of the car compared with traditional AT transmissions. . [0003] At present, there are two types of dual-clutch transmissions: dry type and wet type. The dry type dual-clutch transmission used for small displacement does not use a hydraulic torque converter, and the torque is insufficient at low speeds; while the wet type dual-clutch transmission is complex in structure and requires high technology. It brings disadvantages such as high manufacturing cost and low reliability. In addition, when driving in urban road conditions, the clutch (dry or wet) is ...

Problems solved by technology

[0003] At present, there are two types of dual-clutch transmissions: dry type and wet type. The dry type dual-clutch transmission used for small displacement does not use a hydraulic torque converter, and the torque is insufficient at low speeds; while the wet type dual-clutch transmission is complex in structure and requires high technology. Brings disadvantages such as high manufacturing cost and low reliability

In addition, when driving in urban road conditions, the clutch (dry or wet) is often in a state of frequent shifting and half-clutching, resulting in serious heat generation and high fuel consumption.
