Embodiment Construction

[0033] The content of the present invention will be explained by examples below. This example is only to illustrate the implementation of the present invention, and is not intended to limit the present invention. It should be noted that in the following examples and figures, elements not directly related to the present invention have been omitted, and the dimensions of the elements in the figures are only for easy understanding, and are not used to limit the actual scale.

[0034] The main structure of the transmission: hydraulic torque converter, planetary gear set. like figure 1 shown.

[0035] The sun gear 13 of the planetary gear set, the planetary gear carrier 12 of the planetary gear set, and the ring gear 15 of the planetary gear set have three ends, one end is connected to the input device 2, one end is connected to the output device 3, and the other end is connected to the hydraulic torque converter turbine 8 connect.

[0036] Specific implementation mode 1: the pl...

Abstract

The invention belongs to the field of transmission, and relates to a stepless gearbox. The gearbox solves the problems that the cost is high, a transmission belt is easy to damage, larger load cannot be born, and the like, existing in the existing stepless gearbox. The advantages of the stepless gearbox are achieved, and larger load can also be born. The gearbox has the advantages of simple and reliable structure, compactness and low cost. The gearbox transfers power to a hydraulic torque converter pump impeller 9 and ring gears 15 of a planetary gear set through an input device 2. A planetary carrier 12 of the planetary gear set is connected with an output device 3 to output power; a sun gear 13 of the planetary gear set is connected with a turbine 8 of a hydraulic torque converter, so that the turbine 8 of the hydraulic torque converter rotates reversely. The speed difference between the pump impeller 9 and the turbine 8 of the hydraulic torque converter is increased, so that the bending moment range and the speed change range are expanded. The torque, the rotational speed and the rotation direction of the turbine 8 are changed by the pump impeller, so that the power output of the gearbox is changed.

Description

technical field [0001] The invention belongs to the field of transmission, in particular to a continuously variable transmission. Background technique [0002] Current transmissions are mainly divided into stepped transmissions and continuously variable transmissions. [0003] Stepped transmissions are further divided into manual transmissions, hydraulic automatic transmissions, automated manual transmissions, and dual-clutch transmissions. The operation of manual transmission is complicated, and misuse can easily cause damage to the transmission, and it is tiring to drive in bad traffic conditions. The transmission efficiency of the hydraulic automatic transmission is low, the economy is not good, the structure is complicated, and the maintenance cost is high. The automatic manual transmission has complex structure and high cost. Under complex working conditions, such as long-term traffic jams, the clutch is in a semi-linked state for a long time, and it is prone to fail...
