Problems solved by technology

This type of vehicle gearbox has a relatively simple structure, but there are also some disadvantages: First, when changing gears in motion, since the gears on each shaft are rotating at high speed, it is easy to withdraw and insert each group of gears when changing gears. There is a tooth hitting phenomenon, which leads to damage to the transmission gear; second, when changing gears, you need to step on the clutch first, and then you can move the gear on the fixed shaft to change gears. During the period of time when the clutch is released, the car will lose driving power, which is a safety hazard for heavy vehicles that change gears on the way uphill

Embodiment 1

[0027] This embodiment is a two-gear speed change device (that is, a fixed-axis gear train formed by two sets of fixed shafts), which is composed of an input shaft 8, a power input gear 7, a first-speed conversion assembly 4, a first-speed input gear 6, and a first-speed gear. Output gear 9, second gear input gear 10, first gear input connection gear 11, second gear conversion assembly 12, second gear output gear 13 and output shaft 25 constitute.

[0028] The reverse gear conversion assembly 1, the first gear conversion assembly 4, the second gear conversion assembly 12, the third gear conversion assembly and the fourth gear conversion assembly are the same, and are all composed of a differential 19 and a brake assembly. The following description is based on the reverse gear conversion Component 1 or 4th gear shift component for example.

[0029] The differential 19 is composed of the differential side bevel gear 26, the input half shaft 27 of the differential, the drive shaf...

Embodiment 2

[0038] This embodiment is improved on the basis of Embodiment 1. It is a three-gear speed change device (that is, a fixed-axis gear train formed by three sets of fixed shafts, and one set of fixed shafts is a reversing device). The difference lies in A reversing device consisting of a reverse gear conversion assembly 1, a reverse gear input gear 2, a reverse gear output gear 3 and a bridge gear 5 is added. The side of the fixed axis of the gear, this example adopts the side of being installed on the fixed axis of the first gear. Reverse gear input gear 2 meshes with first gear input gear 6, reverse gear output gear 3 meshes with bridge gear 5, bridge gear 5 also meshes with first gear output gear 9, reverse gear input gear 2 and reverse gear output gear 3 Inter-device reverse gear conversion assembly 1.

[0039] When the reverse gear is selected, operate the gear lever to the reverse gear position, the pull rod on the gear lever will tighten the brake assembly in the reverse ...

Embodiment 3

[0042] This embodiment is improved on the basis of Embodiment 1, and is a three-gear speed change device (that is, a fixed-axis gear train formed by three groups of fixed shafts), and the difference is that the third-speed input gear 14, The third gear speed change device that the third gear conversion assembly 15 and the third gear output gear 24 constitute. This third gear transmission device is installed on the side of the second gear fixed shaft, also can be installed on the side of the first gear fixed shaft, this example adopts the side that is installed on the second gear fixed shaft. The third gear input gear 14 meshes with the second gear input gear 10, the third gear output gear 24 meshes with the second gear output gear 13, and the third gear conversion assembly 15 is installed between the third gear input gear 14 and the third gear output gear 24.

[0043] When selecting the third gear, operate the gear lever to the third gear position, the pull rod on the gear lev...

Abstract

The invention discloses a speed changing method combining ordinary gear trains with differentials and a speed changing device combining ordinary gear trains with differentials, relating to the technical field of mechanical drive. The speed changing device consists of an input shaft, a power input gear, an output shaft and an ordinary gear train formed by two or more than two fixed shafts; each fixed shaft is further internally provided with a differential, and a braking component is arranged on a driving shaft of each differential; two sides of each fixed shaft are respectively provided with an input gear and an output gear in a penetrating way to form an engaging status, and the middle of each fixed shaft is divided into two parts, so that two half shafts and two sun gears provided with the differentials in a penetrating way can be respectively formed; the power input gear arranged on the input shaft is meshed with the input gear on the adjoining fixed shaft, and the output shaft is led out by the output gear; and the invention has the characteristics that the phenomenon of teeth collision can be avoided, the driving power can not be lost instantaneously, the invention is convenient to operate and the like, thereby being suitable for various automobiles, in particular the heavy truck, and the other transport tools.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a speed change method and a speed change device combining a fixed-axis gear train and a differential gear. Background technique [0002] In the prior art, most of the traditional vehicle gearboxes use fixed-shaft gear trains, and shift forks are used to move the gears on the fixed shaft to form different meshing combinations and realize different gear ratios. This type of vehicle gearbox has a relatively simple structure, but there are also some disadvantages: First, when changing gears in motion, since the gears on each shaft are rotating at high speed, it is easy to withdraw and insert each group of gears when changing gears. There is a tooth hitting phenomenon, which leads to damage to the transmission gear; second, when changing gears, you need to step on the clutch first, and then you can move the gear on the fixed shaft to change gears. During this period o...
