Arrangement structure of transmission gear shaft system

Abstract

The invention relates to an arrangement structure of a transmission gear shaft system, which includes an input shaft, a first output shaft and a second output shaft parallel to the input shaft and located on both sides of the input shaft, and fixed on the input shaft A driving gear is provided, and driven gears are sheathed on the output shaft, wherein each driving gear meshes with a corresponding driven gear to drive the driven gears to rotate, and at the same time, the first output shaft and the The second output shaft is also provided with an engaging device that cooperates with the driven gear and is used to switch gears, and the first output shaft and the second output shaft are driven to rotate through the engaging device to output power. Compared with the prior art, the beneficial effect of the present invention is that the interior space of the gearbox is arranged reasonably, the number ratios are well matched, and the axial distance is relatively short.

Description

technical field [0001] The invention relates to an arrangement structure of a gearbox gear shaft system, in particular to a gear shaft arrangement scheme of a six-speed manual gearbox. Background technique [0002] In the early 1990s, the five-speed gearbox quietly emerged. Major car brands, including Mercedes-Benz, Mitsubishi, Honda, Santana, etc., have successively launched models equipped with five-speed gearboxes. Generally speaking, the fifth gear is generally the second overdrive gear, which reduces the variable transmission ratio and increases the speed of the vehicle. This is the new requirement of the user for the performance of the car after the expressway became popular in China at that time. Before long, the market developed such that cars with five-speed transmissions became mainstream. The structural principle of most five-speed gearboxes is to realize the speed change by the direct meshing of the input shaft and the output shaft gear. [0003] The six-speed...

[0004] However, the layout of the existing six-speed gearbox gear shafting is affected by many factors: the matching of the ratio, the matching of the center distance, the limitation of space, the space of the joint device and the gear, the axial size, the balance of the force, etc. , so that the arrangement of its gear shafting is mostly unreasonable. For example, Japanese Patent No. 4382973 disclosed a manual transmission on October 2, 2009, which realizes six-speed manual transmission through the shafting arrangement of gears. However, the manual The shift sequence of the third and fourth gears of the gearbox is inconsistent with the first, second, fifth and sixth gears, and an additional shift conversion mechanism is required to realize it. At the same time, the number is difficult to match and the axial distance is long
