Problems solved by technology

[0002] At present, the CVTs used in automobiles are mainly CVTs in the form of metal belts, and their prices are very high. At high speeds, due to the clutch locking of the hydraulic torque converter of the AT structure automatic transmission, it is more expensive than the CVTs in the form of metal belts. The efficiency must be high, and the continuously variable transmission in the form of a metal belt ca...

Embodiment Construction

[0015] Refer to attached figure 1 , 2 , the structural characteristics of the three-state continuously variable transmission for vehicles are (as attached figure 1 ): the front planetary row (3) and the rear planetary row (6) are coaxial, the outer ring gears (11) of the front and rear planetary rows are integrated or fixedly connected, the front planetary carrier connecting gear (1) receives the power of the engine, and the front sun The wheel (12) is connected to the active part of the existing continuously variable transmission through the hollow shaft, and an asteroid row can be connected in series between the two. By controlling the asteroid row, neutral gear and reverse gear can be realized. The driven part of the existing continuously variable transmission The rear sun gear (13) is connected through the shaft, and the rear planetary carrier (7) outputs power; the clutch (8) is installed on the shaft connected with the rear sun gear (13), and is used to control the dy...

Abstract

A vehicle buncher of three states is featured as setting front and back planetary rows coaxially and forming their external tooth circles in one body , connecting front sun wheel to driving portion of buncher through hollow shaft and connecting driven portion of buncher to back sun wheel through shaft , using back planetary frame to output power , connecting clutch one on shaft connected to back sun wheel and connecting clutch two on shaft connected to front sun wheel , setting torque regulation unit on front planetary frame to correspond to frame planetary wheel coaxially and setting clutch three on front planetary frame to correspond to front planetary wheel coaxially .

Description

technical field [0001] The invention relates to a three-state continuously variable transmission for vehicles, which is suitable for various automobiles, tractors, motorcycles, and other motor vehicles and electric vehicles as the continuously variable transmission. Background technique [0002] At present, the CVTs used in automobiles are mainly CVTs in the form of metal belts, and their prices are very high. At high speeds, due to the clutch locking of the hydraulic torque converter of the AT structure automatic transmission, it is more expensive than the CVTs in the form of metal belts. The efficiency must be high, and the continuously variable transmission in the form of a metal belt cannot be used for engines above 4.0 liters (at present, the automatic transmission of high-end cars can only use the form of a hydraulic torque converter plus a double-row planetary gear). At present, the automatic transmission for automobiles is mainly in the form of a hydraulic torque con...
