Problems solved by technology

However, this multi-stage transmission causes the transmission system to be bulky, complex in structure, high in cost and low in transmission efficiency.
Especially in the case of continuously variable transmission with large transmission ratio, the above-mentioned problems are particularly serious

Embodiment Construction

[0026] figure 1 A schematic diagram of the first differential planetary gear transmission mechanism 1 in the present invention is specifically shown. The second and third differential planetary gear transmission mechanisms 2 and 3 have the same structure as the first differential planetary gear transmission mechanism. In this embodiment, the differential planetary gear transmission mechanism 1, 2, 3 is a gear transmission mechanism, a typical example of which is a differential. Thus, in figure 1 2 and 3 are also similarly constructed as the second differential 2 and the third differential 3 (in figure 1 not shown). Of course, the differential planetary gear transmission mechanism may also be a planetary gear transmission mechanism composed of spur gears, or a planetary gear transmission mechanism composed of bevel gears.

[0027] exist figure 1It can be seen from the figure that the first differential 1 includes a first half shaft 11 , a second half shaft 12 and a housin...

Abstract

The invention discloses a transmission system which comprises a first differential planet gear mechanism, a second differential planet gear mechanism, a third differential planet gear mechanism and a plurality of speed change devices. The transmission system is simple in structure and low in cost, can have a very small size, can output the more stable rotating speed, and can achieve stepless speed change within a certain range.

Description

technical field [0001] The invention relates to a transmission system. Background technique [0002] In transmission systems such as transmissions (or transmissions), gears are the most basic transmission parts. The transmission ratio (also known as the speed ratio) of a gear train depends on the gear ratio. When the transmission ratio is very large, the rotation speed of the pinion is very high, so the teeth of the pinion are easily fatigued and broken. In order to avoid this situation, in the prior art, a large transmission ratio is usually distributed to several stages, so that each stage of the transmission system has an appropriate transmission ratio. However, this multi-stage transmission causes the transmission system to have a large volume, complex structure, high cost and low transmission efficiency. Especially under the situation of stepless speed change of large transmission ratio, above-mentioned problem is especially serious. In particular, in the wind power...
