Problems solved by technology
With the change of national policy, the continuous vigorous development of the domestic logistics industry and the implementation of the weight-based toll policy, the application of heavy trucks in the logistics industry is increasing. However, the fuel economy of ordinary transmissions is not high, the noise is large, and the application range is relatively large Narrow, more and more unable to meet the needs of the market

Embodiment Construction
[0015] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation mode combined with the accompanying drawings.
[0016] It can be seen from the attached figure that the figure 1 As shown, the twelve-speed overdrive helical gear transmission of the present invention has an input torque of 2500N / M. The main transmission has a double countershaft structure, the auxiliary transmission is designed as a planetary mechanism, the main transmission has six forward gears and one reverse gear, and the auxiliary transmission has two high and low gears. The main transmission and the auxiliary transmission together form twelve forward gears and two reverse gear. When the auxiliary transmission is in the low gear, the power of the engine is transmitted to the input shaft 1, and the one-shaft gear 14 is connected with the input shaft 1 as a whole by a spline, and the power is transmitted to the one-shaft gear...

The invention provides a technical scheme of a twelve-gear overdrive gear helical tooth transmission for a heavy-duty truck. The twelve-gear overdrive gear helical tooth transmission comprises a main transmission and an auxiliary transmission; the main transmission comprises an input mechanism and a speed changing mechanism; main tank gears are all helical gears; the input mechanism comprises an input shaft and two auxiliary shafts meshed with the input shaft; the speed changing mechanism comprises a main shaft, an idle wheel, four main shaft sliding sleeves being in spline connection with the main shaft and sliding along the main shaft left and right, gear auxiliary shaft gears in spline connection with the auxiliary shaft, and gear main shaft gears in spline fit with the main shaft sliding sleeves; the four main shaft sliding sleeves are uniformly distributed among the gear main shaft gears; the two auxiliary shafts are parallel to the main shaft and are arranged at the two sides of the main shaft respectively; the idle wheel is meshed with a reverse gear auxiliary shaft gear and a reverse gear main shaft gear; the auxiliary transmission comprises a planetary mechanism in spline connection with the main shaft. In the scheme, the speed ratio of the highest gear is 0.79, the fuel economy and the transport efficiency of the whole truck are greatly improved, and the twelve-gear overdrive gear helical tooth transmission is long in service and good in fuel economy.
Description
technical field [0001] The invention relates to a transmission for heavy-duty trucks, in particular to a twelve-speed overdrive helical gear transmission for heavy-duty trucks. Background technique [0002] At present, there are many kinds of transmissions for heavy-duty trucks in China, but most of the main boxes are direct transmissions with large head gear speed ratio and strong climbing ability, and most of them are used in engineering vehicles. With the change of national policy, the continuous vigorous development of the domestic logistics industry and the implementation of the weight-based toll policy, the application of heavy trucks in the logistics industry is increasing, but the fuel economy of ordinary transmissions is not high, the noise is large, and the application range is relatively large. Narrow, more and more unable to meet the needs of the market. Contents of the invention [0003] In order to solve the above technical deficiencies, the present inventio...
