Embodiment Construction

[0041] figure 1 It is a schematic diagram of a three-way automatic transmission. In the driven gear 3 of the forward gear, ternary mechanical clutch modes such as overrunning clutch 4, screw clutch 5 and centrifugal clutch 6 are adopted, which cooperate with each other to form the relative movement and relative stillness of the gear positions, so as to realize the fully mechanical automatic speed change of the motor vehicle.

[0042] The overrunning clutch 4 is contained in the inside of the forward gear driven gear 3; in the overrunning clutch 4 there is a sprag type overrunning clutch 4-1 ( image 3 ), or roller type overrunning clutch 4-2 ( Figure 4 ), or spiral overrunning clutch 4-3 ( Figure 5 ) and other overrunning clutches. Driven gear 3 forms relative motion or relatively static to realize automatic clutching between two axles 2 that are connected with drive wheel transmission shaft through overrunning clutch 4 . If the rotational speed of the driven gear 3 is g...

Abstract

The invention provides a ternary automatic transmission for a motor vehicle and relates to a fully-mechanical automatic transmission. The ternary automatic transmission for the motor vehicle comprises a first shaft (1), an intermediate gear shaft (9) and a second shaft (2), wherein the first shaft (1) is in clutch connection with an output shaft of a motor; forward-gear driven gears (3) on the second shaft (2) cooperate with one another to form relative motion and relative rest of gears by adopting a ternary mechanical clutch mode of an overrunning clutch (4), a spiral clutch (5), a centrifugal clutch (6) and the like so as to realize fully-mechanical automatic transmission of the motor vehicle. The ternary automatic transmission for the motor vehicle has the advantages of simple and compact structure, adaptation to the installation position and size of the conventional manual transmission, and positive effects of sliding in gear, saving fuel oil, reducing emission, improving riding comfort, prolonging the service life of each of the motor and a transmission system and the like due to reasonable construction and is convenient for manufacture and installation.

Description

1. Technical field [0001] The invention relates to a motor vehicle automatic transmission, in particular to a fully mechanical automatic transmission for a motor vehicle. 2. Background technology [0002] Automatic transmissions for motor vehicles have hitherto been limited to passenger cars. The principle is that the computer board controls the clutches, brakes and hydraulic oil solenoid valves of the one-way gears of each gear through the information transmitted by the vehicle speed sensor, forming a coaxial (also called epicyclic) transmission of the sun, planetary gears and ring gears. Various speed ratios between, to achieve automatic gear shifting. In order to make the car body run smoothly, a fluid coupling is arranged at the output end of the engine and the input end of the transmission, which acts as a clutch. In order to overcome the disadvantage of low transmission efficiency caused by the hydraulic slip of the fluid coupling, the displacement of the engine is u...
