Embodiment Construction

[0008] Take the RTS-11909A series transmission as an example: the RTS-11909A series transmission consists of a front five-speed main transmission and a two-speed auxiliary transmission. reverse gear. See the main structure diagram. In the main transmission, shaft 1 (input shaft) and shaft 1 gear 2 are connected by splines, and shaft 1 gear 2 can float in the radial direction. The gears on the intermediate shaft A are all matched with the intermediate shaft with a certain amount of interference and connected with crescent keys or long keys except that reverse gears 11, 22 and low gears 9, 25 are integrated with the intermediate shaft A. The gears 31, 30, 24 on the shaft B (main shaft) are supported on the shaft B by their inner diameters, and are in a floating state with the shaft B in the radial direction. They are positioned axially by means of a long hexagon key and a splined washer mounted on shaft B, and do not require adjusting shims. In the auxiliary transmission, the ...

Abstract

The invention relates to a self-boosting type 9-gear double-intermediate-shaft full synchromesh transmission which comprises an input shaft, an output shaft, intermediate shafts, two shafts, a lock pin type inertial synchronizer, a gear box body, a gear, and the like. The self-boosting type 9-gear double-intermediate-shaft full synchromesh transmission is characterized by consisting of a front 5-gear main transmission and a 2-gear setting auxiliary transmission, wherein the main transmission is manually manipulated, and the auxiliary transmission is pneumatically manipulated. The main transmission and the auxiliary transmission of the self-boosting type 9-gear double-intermediate-shaft full synchromesh transmission adopt a double-intermediate-shaft structure and a full synchromesh. The self-boosting type 9-gear double-intermediate-shaft all synchromesh transmission has the advantages of large torque reserve coefficient, strong climbing capacity, wide speed ratio range, various power taking forms, and the like.

Description

technical field [0001] The invention provides an automatic booster type 9-speed double countershaft full synchronizer transmission, in particular the synchronizer technology for multi-gear conversion of automobiles. Background technique [0002] After China entered the customs, while the economy is developing rapidly, the automobile transportation industry is also developing rapidly, especially the trend of large-tonnage heavy-duty vehicles being sought after by users is becoming more and more obvious. Car owners hope that the stronger the carrying capacity of heavy trucks, the better. The flexibility of the system, safety factor, service life, ability to pass on rough roads and slopes, and fuel consumption are also the concerns of car owners. Saving fuel means saving money, and saving money also means increasing revenue. Therefore, in the same carrying capacity Under such circumstances, car owners are paying more and more attention to the fuel-saving performance of heavy-du...
