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 cannot be used for engines above 4.0 liters.
At present, the automatic transmission for automobiles is mainly in the form of a hydraulic torque converter plus a double-row planetary gear. The main disadvantage of this structure is that the efficiency of the hydraulic torque converter is low, and it is not a true stepless speed change.
These two transmissions are currently not capable of self-production in our country

Embodiment Construction

[0015] Reference attached figure 1 , 2 , Three-state vehicle continuously variable transmission structure features (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 fixed, and the front planet carrier is connected to the gear (1) to receive 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 a hollow shaft. An asteroid row can be connected between the two. Neutral and reverse gears can be realized by controlling the asteroid row. The driven part of the existing continuously variable transmission The rear sun gear (13) is connected through the shaft, and the rear planet carrier (7) outputs power; the clutch (9) is installed on the shaft connected to the rear sun gear (13) to control the dynamic and static conversion of the rear sun gear (13), The clutch (8) i...

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 continuously variable transmission for a three-state vehicle, which is suitable for various automobiles, tractors, motorcycles, and other motor vehicles and electric vehicles as a continuously variable transmission. Background technique [0002] The current continuously variable transmission used in automobiles is mainly a metal belt type continuously variable transmission, which is very expensive. At high speeds, the hydraulic torque converter of the AT structure automatic transmission uses a clutch to lock, making it more than a metal belt type continuously variable transmission. The efficiency should be high, and the continuously variable transmission in the form of a metal belt cannot be used for engines above 4.0 liters (currently, the automatic transmission of high-end cars can only use a hydraulic torque converter and a double-row planetary gear). At present, the automatic transmission for automobiles is mainly in the form ...
