Problems solved by technology

This type of transmission is often used in conjunction with a hydraulic torque converter before, and it can shift gears without cutting off the engine power, but the transmission efficiency is low; Interconnected and nested, resulting in a very complex structure of the entire transmission and difficult layout, which brings great difficulties to manufacturing and maintenance, especially the hobbing method cannot be used for the processing of the ring gear, so the processing efficiency is low and the accuracy is poor higher cost

Embodiment Construction

[0068] Figure 3a A schematic diagram showing the basic structure of an embodiment of the mechanical transmission of the present invention, which includes a planetary gear mechanism A, a housing C, and also includes the related components that can realize the planetary gear mechanism A and the housing C. Relatively rotating braking mechanism, that is, a braking mechanism installed between the planet carrier assembly 4 and the housing C to realize no relative rotation between the planet carrier assembly 4 and the housing C, is called For the planetary carrier brake mechanism B C . The planetary gear mechanism A includes an input sun gear assembly 1, an output sun gear assembly 3, two planetary gear assemblies 2 arranged around the input sun gear assembly 1 and the output sun gear assembly 3, and a planet carrier assembly 4 and locking mechanism 5. Here, three or another number (such as one or four) of planetary gear assemblies 2 can also be provided, preferably evenly spaced...

Abstract

The invention relates to a planetary gear mechanism which comprises an input sun gear assembly (1), at least one planet wheel assembly (2), a planetary carrier assembly (4) and an output sun gear assembly (4), wherein the input sun gear assembly, the planetary carrier assembly and the output sun gear assembly are provided with coincident axes of rotation, and every two of the input sun gear assembly, the planetary carrier assembly and the output sun gear assembly can rotate relative to each other; the planetary carrier assembly and / or the output sun gear assembly can be fixed and can be selectively fixed, moreover every two of the input sun gear assembly, the planetary carrier assembly and the output sun gear assembly can be fixed mutually, wherein the locking and fixing can be carried out selectively; the planet wheel assembly can be rotatably installed on the planetary carrier assembly surrounding the axis; and each planet wheel assembly comprises two planet wheel (21, 22) which are connected together through a shaft to rotate coaxially and synchronously, and one of the two planet wheel is meshed with the input sun gear, while the other planet wheel is meshed with the output sun gear. The invention also relates to a speed changer comprising the planetary gear mechanism.

Description

technical field [0001] The invention relates to a planetary gear mechanism and a mechanical transmission including the planetary gear mechanism, in particular to a gear transmission applied to vehicles. Background technique [0002] In practical applications, there are two types of gear transmissions: fixed shaft type and planetary gear type. [0003] Such as figure 1 Shown is a schematic diagram of a fixed shaft gear transmission with three fixed gear shafts: the first shaft (input shaft) Z 1 , the second axis (output axis) Z 2 and intermediate axis Z 3 , the first axis Z 1 and the second axis Z 2 Arranged at a distance apart in the axial direction, the rotation axes are coincident and can be rotated relative to each other, the intermediate axis Z 3 with the first axis Z 1 and the second axis Z 2 Arranged in parallel. First axis Z 1 1 gear a is mounted on the body 1 , both rotate synchronously; the second axis Z 2 3 gears b 2 、c 2 、d 2 , these three gears are...
