Abstract

PURPOSE: To reduce a cost of manufacture so as to improve efficiency of manufacture by eliminating a loss of transmission according to an automatic stepless speed changer in the past, and improving efficiency of fuel consumption, also to form various gears in the past into a combined simplified structure. CONSTITUTION: Power is transmitted from a power input shaft 1 to a propeller shaft 8, to rotate the propeller shaft 8, and by rotating the propeller shaft 8, a base unit 9 is rotated similarly to the propeller shaft with the power shaft 1 and the propeller shaft 8 serving as the center. While rotation of the base unit 9 approaches to and separates from a rotational speed of the power shaft, rotational ratio of the power input shaft to the propeller shaft is changed steplessly by gears 3 to 7.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used as an automatic continuously variable transmission for automobiles and the like. 2. Description of the Related Art An automatic continuously variable transmission using a steel belt or the like is used in a conventional vehicle or the like. [0003] In the conventional continuously variable transmission, there is a transmission loss due to the slip of the steel belt,
There is a problem that it is difficult to use for large vehicles that require a lot of horsepower. The present invention eliminates power loss by transmitting power transmission by a combination of gears 2-7. Combining conventional gears lowers production costs and facilitates manufacturing. [Operation] 1. Power transmission is transmitted from 1 input shaft to 2 ohm gears, 3 spiral gears, 4 super gears, 5 super gears, 6 bevel gears, 7 bevel gears, and 8 propeller shafts. 2, the direction of power transmission is 1 counterclockwise, 2 clockwise, 3 clockwise, 3a counterclockwise, 4a clockwise, 4a clockwise, 4a clockwise, 5 clockwise. 5a clockwise, 6 counterclockwise, 6a clockwise, 7 counterclockwise, 8 counterclockwise, 9 counterclockwise. 3, conversely, when a force is applied from the propeller shaft, 8, 7, 6, 5,
It is transmitted as 4, 3, 2, 1, but before it reaches 1, 6, 5,
4 and 3 try to rotate around the axes of 10 and 11, but
When the rotation is transmitted from 3 to 2, the rotation of 3, 4, 5 and 6 stops and works in the direction of the propeller shaft. When a force acts on the propeller shaft direction, it is stopped by the thrust metal of 14 and the force becomes the rotation direction of the propeller shaft and the input shaft, turning 1 to 1 rotation direction by the angle of 2 ohm gear and 3 spiral gear
Taking a car as an example, it becomes engine braking. 4. The input shaft and the propeller shaft rotate in the same direction, but the rotation ratio is 2, 3, 4, 5, 6, 7 depending on the gear ratio.
The rotation ratio is high. When 7, 8 starts to rotate, the rotation direction of 3, 4, 5, 6 that rotates around the 10 and 11 axes is 10,
11, 3, 4, 5, 6, 9 all rotate in the rotation direction of 8, and the gear ratio is reduced by the number of rotations of 7, 8 and, taking an automobile as an example, the description will be low, second third, top. It is a continuously variable transmission whose gear ratio changes. A conventional electromagnetic clutch and the like are connected to a continuously variable transmission, and then a forward transmission and a reverse transmission are attached and used. As compared with the conventional transmission, the automatic continuously variable transmission with each gear combination can eliminate the transmission loss and the fuel loss due to the emptying and the like of the manual transmission, thereby improving the fuel consumption efficiency. By using each conventional gear, the assembling becomes easy and the manufacturing cost can be reduced. [0007]

Claims (1)

Claims: 1 to 14 of the reference numerals are combined as shown in FIGS. 2. Propeller shaft 8 transmits power from power input shaft 1 to propeller shaft 8 by combining parts 1 to 14 shown in FIGS. 4 to 6 and perspective views as shown in FIGS.
Rotates, and the rotation of the propeller shaft 8 causes the mother body 9 to rotate about the power shaft 1 and the propeller shaft 8 in the same manner as the propeller shaft. This is a system in which the rotation ratio of the power input shaft and the propeller shaft is continuously changed by the gears 3 to 7 while the rotation of the mother body 9 approaches or deviates from the rotation speed of the power shaft.
