Problems solved by technology

However, the master and driven friction plates of the multi-plate clutch in the disengaged state slip through each other due to the lubricating oil, resulting in relatively large frictional resistance, which reduces the transmission efficiency of the transmission accordingly.

Embodiment Construction

[0015] Embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0016] In this embodiment, the driving gear 1 on the main shaft of the engine rotates together with the engine. Drive the driving side / driven side of the two clutches (the first clutch 3 and the second clutch 2), and the driven side / driving side of the two clutches are respectively connected to the corresponding input shafts. Two input shafts are arranged in parallel at a certain distance, namely the first input shaft 24 and the second input shaft 10 .

[0017] The first gear driving gear 23, the third gear driving gear 20, the fifth gear driving gear 19, the seventh gear driving gear 22 and the reverse driven gear 7 of the odd-numbered gear group are arranged on the first input shaft 24; The second gear driving gear 6, the fourth gear driving gear 4, the sixth gear driving gear 9 and the reverse gear driving gear 21 of the group are arranged on the second in...

Abstract

The invention belongs to a speed changer, and particularly relates to a three-shaft double-clutch speed changer. The speed changer is characterized in that the speed changer comprises two clutches, two input shafts and an output shaft, wherein the two clutches are driven by gear transmission or belt transmission by an engine and connected with the corresponding input shafts respectively; an odd-gear driving gear set is arranged on one input shaft; an even-gear driving gear set is arranged on the other input shaft; a driven gear set is arranged on the output shaft; driving gears of the two input shafts share the corresponding driven gears; reverse gear driving gears are arranged on one input shaft; reverse gear driven gears are arranged on the other input shaft and engaged with the reverse gear driving gears; the soldered tooth ring part of a parking mechanism is fixedly connected with a box body; and the parking mechanism is matched with an output shaft synchronizer and achieves a parking function by pulling a shifting fork with gear shifting stay wire. The speed changer is compact in structure, the cost is lowered, the axial length of the speed changer is shortened as no coaxial shaft is adopted, the system rigidity is improved, and the performance is reliable.

Description

technical field [0001] The invention belongs to the category of transmissions, in particular to a three-shaft double-clutch transmission. 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 dual-clutch single-shaft output maximizes...
