Embodiment Construction

[0022] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation manner.

[0023] As shown in the attached figure, a ten-speed transmission with dual intermediate shafts and full synchronizer is a two-stage structure composed of a main box and an auxiliary box. There is a main transmission in the main box, and an auxiliary transmission in the auxiliary box. The main transmission has five forward gears. and one reverse gear, the auxiliary transmission has two gears, constitutes a 5×2 structure, forming ten forward gears and two reverse gears, the main transmission includes an input mechanism and a speed change mechanism, and the input mechanism includes an input shaft and two Subshafts-left subshaft 37 and right subshaft 39; the transmission mechanism includes a main shaft 1, an idler 30, a main shaft shifting self-energizing lock pin synchronizer 2 that is splined to the main shaft 1 and can sli...

Abstract

The invention discloses a dual-middle-shaft all synchromesh ten-gear transmission, which has a two-segment structure consisting of a main tank and an auxiliary tank, wherein a main transmission is arranged in the main tank; an auxiliary transmission is arranged in the auxiliary tank; the main transmission is provided with five forward gears and a reverse gear, and the auxiliary transmission is provided with two gears, so that a 5*2 structure is constructed, and ten forward gears and two reverse gears are formed; the main transmission comprises an input mechanism and a speed change mechanism; the input mechanism comprises an input shaft and two auxiliary shafts; the two auxiliary shafts are parallel to a main shaft, and are arranged on both sides of the main shaft at 180 degrees; an idler wheel is meshed with reverse gears of the auxiliary shafts; the auxiliary transmission comprises an auxiliary tank planet mechanism which is connected with the main shaft through a spline; the output end of the auxiliary tank planet mechanism is provided with an auxiliary tank lock ring synchromesh; and a main shaft gear is positioned axially through a spline separation blade. In the design, the entire set of device has the advantages of simple structure, reliable connection, flexible shifting, high generality, convenience for loading in series, high assembling property, full adaptability to the requirements of users and wide market prospect.

Description

technical field [0001] The invention relates to a ten-speed transmission with double countershaft full synchronizer. Background technique [0002] The transmission with double countershaft structure has the advantages of compact structure, large transmission torque and long service life, and is widely used in medium and heavy trucks. At present, most of the main case of double countershaft structure transmissions use sliding sleeves to shift gears, which makes shifting difficult and requires high driving skills of the driver; at the same time, the positioning structure of the main shaft assembly is realized by bearings. The axial positioning of the assembly requires many parts, high price and complicated assembly. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a ten-speed transmission with double intermediate shafts and full synchronizers that can meet the requirements of large load capacity, good fuel econo...
