Problems solved by technology

The base utilization of legacy MT parts is limited, so the development cost is relatively high
[0005] The dual-shaft output of the combined clutch shortens the axial length of the transmission and effectively improves the rigidity of the system. It is suitable for the overall machine structure with small axial size requirements. technical difficulties and high development costs

Abstract

The invention belongs to transmissions, in particular to a double-clutch transmission with a synchronizer parking device and without a reversing shaft. The double-clutch transmission is characterized in that a double-clutch device formed by integrating two clutches is adopted; simultaneously, the double-clutch transmission comprises a double-transmission input shaft formed by combining an inner shaft and an outer sleeve shaft; even-gear gear sets and odd-gear gear sets of the double-clutch transmission are respectively connected with the two clutches through the outer sleeve shaft and the inner shaft; the parking device is installed on a certain output shaft; a joint gear ring fixedly connected with a box body is matched with an output shaft synchronizer or a gear-shifting gear sleeve, so that an output shaft is locked; therefore, the parking function is realized; in addition, by utilizing characteristics of a three-shaft transmission, one output shaft is used as a reverse-gear idler shaft, and another output shaft outputs reverse-gear power. According to the invention, a special parking mechanism and an independent reverse-gear idler shaft are saved; therefore, the integral structure is compact, and the occupation space is small.

Description

technical field [0001] The invention belongs to the category of transmissions, in particular to a dual-clutch transmission with a synchronizer parking device and no reverse shaft. Background technique [0002] The dual-clutch transmission realizes the shifting action through the matched switching of the two clutches, and the shifting is fast and smooth. During the shifting process, the power of the engine is continuously transmitted to the wheels to realize power shifting and ensure that the vehicle has good acceleration performance. The dual-clutch transmission is developed based on the parallel-shaft manual transmission, and it inherits many advantages of the manual transmission, such as high transmission efficiency, compact installation space, light weight, and low price. [0003] At present, there are mainly three types of dual-clutch transmission structures: dual-clutch single-shaft output, combined clutch single-shaft output and combined clutch dual-shaft output. The...
