Embodiment Construction

[0019] Such as figure 1 The shown first embodiment of the dual-clutch five-speed transmission of the present invention includes an engine input shaft 1, a first layshaft 7, a second layshaft 13, and an intermediate shaft 19 arranged parallel to each other and rotatable around its own axis, The axes of the engine input shaft 1 and the intermediate shaft 19 are located in the middle of the axes of the two layshafts.

[0020] Such as figure 2 or image 3 As shown, the right end of the input shaft 1 of the engine is equipped with an input shaft gear 2, and the input shaft gear 2 meshes with an odd-numbered clutch driving gear 3 and an even-numbered clutch driving gear 4 with different transmission ratios;

[0021] The odd-numbered gear clutch 5 and the even-numbered gear clutch 6 are respectively fixedly installed on the right ends of the first countershaft 7 and the second countershaft 13 through the internal odd-numbered friction plates 26 or even-numbered friction plates 27,...

Abstract

The invention relates to a double-clutch transmission mechanism. The mechanism comprises a motor input shaft, a first auxiliary shaft, a second auxiliary shaft and an intermediate shaft which are arranged in parallel and can rotate around respective axis, wherein the axes of the motor input shaft and the intermediate shaft are positioned between the axes of the two auxiliary shafts. The mechanism adopts a position gear as a carrier gear to directly connect with a differential mechanism, effectively reduces number of gears, and has the advantages of simpler whole transmission structure, high integrated level and reduction in cost. In addition, the double-clutch transmission mechanism adopts lower transmission series on common positions and can effectively save energy and improve efficiency.

Description

technical field [0001] The present invention relates to a mechanism for transmitting torque from an input shaft of an engine to a drive system, and in particular to a dual clutch transmission mechanism. Background technique [0002] There are three main types of automatic transmissions used in the world: hydraulic automatic transmission (AT), electromechanical automatic transmission (AMT) and mechanical continuously variable automatic transmission (CVT). In the field of electronically controlled mechanical automatic transmission, a new transmission mode has appeared, that is, dual clutch automatic transmission (Dual Clutch Transmission), which not only inherits the simple structure, compact installation space and weight of AMT and manual transmission. It has many advantages such as light weight, high transmission efficiency, and low manufacturing cost, and it also combines the good characteristics of AT uninterrupted power and rapid and smooth shifting. The principle of dua...
