Embodiment Construction
[0017] Below in conjunction with accompanying drawing, overall structure and working process of the present invention are described in detail:
[0018] The nine-speed double countershaft transmission: as figure 1 As shown, the described nine-speed transmission has a combined main and auxiliary case double countershaft structure, which includes an input shaft 1, the input gear is integrated with the input shaft, and the right end of the input shaft 1 is connected to the second shaft 32 through the front bearing 3 of the two shafts. There are 5 gears (6, 7, 9, 10, 12) on the second shaft 32, of which 12 is the reverse gear of the second shaft, and the rest are forward gears, between the gear 1 of the first shaft and the third gear 6 of the second shaft 1. A third and fourth gear synchronizer 5 and a first and second gear synchronizer 8 are respectively arranged between the two-shaft second-gear gear 7 and the second-shaft first-gear gear 9, and between the two-shaft low gear 10 ...

The invention provides a nine-gear double-intermediate-shaft transmission. The nine-gear double-intermediate-shaft transmission mainly solves the problem that an existing nine-gear double-intermediate-shaft transmission is high in noise and heavy in weight, cannot easily adapt to complex road surface working conditions, and is complex in structure. The nine-gear double-intermediate-shaft transmission is of a structure with combination between a main box and a secondary box and double intermediate shafts, a forced lubricating oil pump is assembled at the front end of the nine-gear double-intermediate-shaft transmission in a matched mode, main components of the nine-gear double-intermediate-shaft transmission can be lubricated, and a forced cooling connector is reserved; a main-and-secondary box interlocking mechanism is assembled on the nine-gear double-intermediate-shaft transmission, so that it is ensured that gear engagement of the main box cannot be carried out on the situation that gear engagement of the secondary box of the nine-gear double-intermediate-shaft transmission is not in place; thrust roller bearings are adopted for the main box and the secondary box of the nine-gear double-intermediate-shaft transmission and are used for balancing axial force, influence caused by the axial force on other components is reduced, and traditional tapered roller bearings are not adopted; a gear shifting booster is assembled on the nine-gear double-intermediate-shaft transmission in a matched mode, so that the comfort degree of gear shifting is improved; in order to achieve safety, a high reverse gear and a high climbing gear of the nine-gear double-intermediate-shaft transmission are locked; a side force taking connector and a rear force taking connector are reserved on the nine-gear double-intermediate-shaft transmission, and the extension design can be achieved.
Description
technical field [0001] The invention relates to a nine-speed double countershaft transmission, which belongs to the field of automobile transmissions. Background technique [0002] At present, the nine-speed medium-sized transmissions at home and abroad are mainly products with straight teeth and cast iron casings. This type of transmission has high noise and heavy weight, which affects the fuel economy and performance of the transmission; secondly, the existing nine-speed medium-sized transmissions Basically, it does not match the forced lubrication and cooling system, and it is difficult to adapt to complex road conditions; thirdly, at present, domestic and foreign related helical gear products are designed with tapered roller bearings, and the assembly is very complicated. Contents of the invention [0003] The invention provides a nine-speed dual-countershaft transmission, which mainly solves the problems of the existing nine-speed double-countershaft transmission with...
