Problems solved by technology

In the existing industrialized dual-clutch automatic transmission transmission scheme, two wet multi-disc clutches are integrated together due to the coaxial drive method of the sleeve and shaft. The dual clutch structure, support and lubrication structure are very complicated, difficult to process and high in manufacturing cost

Embodiment Construction

[0020] see Figure 1-2 , dual clutch automatic transmission such as figure 1 As shown, the input shaft gear 332 is installed on the engine input shaft 31, which includes two independent single clutches 35, 36, wherein the driving gear 33 of the odd-numbered gear clutch 35 and the driving gear 34 of the even-numbered gear clutch 36 are respectively different. The transmission ratio meshes with the input shaft gear 332, the odd-numbered gear clutch driving gear 33 is fixed on the first countershaft 37, the even-numbered gear clutch driving gear 34 is fixed on the second countershaft 313, the first countershaft 37 and the second countershaft 313 They are respectively arranged on two sides of the input shaft 31 and are all parallel to the input shaft 31 .

[0021] The odd-numbered gear clutch 35 and the even-numbered gear clutch 36 are respectively fixedly mounted on the right ends of the first countershaft 37 and the second countershaft 313 through the internal odd-numbered fri...

Abstract

The invention relates to a dual-clutch automated transmission. An input shaft gear is arranged on an input shaft of an engine. The dual-clutch automated transmission comprises two independent monomer clutches, wherein the driving gear of the odd-gear clutch and the driving gear of the even-gear clutch are meshed with the input shaft gear in different transmission ratios respectively; the driving gear of the odd-gear clutch is fixed on a first secondary shaft; the driving gear of the even-gear clutch is fixed on a second secondary shaft; and the first secondary shaft and the second secondary shaft are arranged on two sides of the input shaft respectively and are parallel to the input shaft. In the dual-clutch automated transmission, an integrated dual-clutch is separated into two monomer clutches and the coaxial structure of the traditional dual-clutch transmission is transformed into a parallel structure, so that the manufacturing and processing difficulty of the dual-clutch transmission is simplified and the cost is reduced.

Description

technical field [0001] The invention relates to a dual-clutch transmission, in particular to a parallel-shaft dual-clutch automatic transmission for automobiles. Background technique [0002] Dual-clutch automatic transmission has two sets of power transmission devices and two sets of clutch systems. The power interruption time of the system is less. Due to the use of conventional fixed-axis gear transmission, the transmission efficiency is relatively high and the production process is mature. Since the successful installation of Volkswagen, it has gradually Become a hot spot in the development of the automotive industry. The wet multi-plate clutch has the characteristics of stable friction performance, good controllability and control quality, small and uniform wear, large transmission torque, and can use lubricating oil to cool related heat-generating components, so it has been widely used in dual-clutch automatic transmission systems. application. In the existing indust...
