Problems solved by technology

[0002] The current domestic medium-sized multi-speed car transmissions with sub-boxes are mostly double countershaft structures. The main box has no synchronizer, which has problems such as inconvenient operation, difficult gear shifting, and high work intensity. It is difficult to meet the needs of the rapid development of domestic medium-sized cars.

Embodiment Construction

[0018] Such as figure 1 , 2 As shown, the medium-sized automobile transmission with the main and auxiliary cases of the present invention includes the housing 3 of the main transmission, the rear housing 12 of the auxiliary transmission connected to the rear of the housing 3, the main transmission is a parallel shaft transmission structure, and the auxiliary transmission is Planetary transmission structure, high and low gear area switching with pneumatic shifting, the specific structure is as follows:

[0019] The first shaft 1 of the main transmission is supported on the housing 3 through a cylindrical roller bearing 2 with a snap ring on the outer ring. One end of the second shaft 4 is supported on the inner hole of the first shaft 1 by a full roller bearing, and the other end is supported on the housing 3 by a cylindrical roller bearing 7 with a stop ring on the outer ring. Bearings are vacantly sleeved on the second shaft 4, and each synchronizer tooth seat is fixed on t...

Abstract

The medium -sized car transmission with the main and auxiliary box of the present invention is a fixed axis transmission structure in the middle shaft.The gear uses the lock ring synchronizer to change the gear, and the inverted gear uses a mesh set.The auxiliary transmission is also a planetary transmission structure. It is divided into two gears of high and low. It uses a large -capacity synchronizer to change the gear of the lock ring.The combination of the main and auxiliary transmissions forms 8 forward gear and 2 reversing configurations.The present invention has the advantages of large number of loading capacity, large number of gears, all -synchronized gear changes, speed -match matching, and other comparison distribution, main and sideline linkage control, lightweight shift, environmental protection and energy saving, etc.2. The road conditions are strong and can better meet the current development needs of domestic cars.

Description

technical field [0001] The invention discloses a medium-sized automobile transmission with main and auxiliary cases, belonging to the technical field of automobile transmission parts. Background technique [0002] The current medium-sized multi-speed car transmissions with sub-boxes in China are mostly double countershaft structures. The main box has no synchronizer, which has problems such as inconvenient operation, difficult gear shifting, and high work intensity. It is difficult to meet the needs of the rapid development of domestic medium-sized cars. . Contents of the invention [0003] In order to solve the above problems, the present invention provides a compact structure, multiple gears, large speed ratio range, reasonable matching, good meshing performance, low price, auxiliary case planetary gear transmission structure, main and auxiliary case full synchronizer gear shifting Multi-speed medium-duty car transmission. [0004] In order to achieve the above object,...
