Abstract

PROBLEM TO BE SOLVED: To provide a speed change without needless operation or complicated structure at the time of speed change. In order to solve the above-mentioned problem, the continuously variable transmission according to the first aspect is provided with a component in which an impeller for receiving energy and a gear having a different diameter are integrated on the input side as shown in FIG. The parts are set so that they can rotate freely without being fixed. On the output side, gears of a diameter that mesh with the gears on the input side are integrated by coupling. By setting the input side gear and the output side gear from the beginning, it is not necessary to exchange the gears at the time of shifting. To change the speed, a continuously variable transmission that receives energy, changes the impeller (3), (4), (5), or changes the pressure of the fluid that is the energy source for rotating the impeller to change the rotation speed. Thereby, a complicated structure and operation can be eliminated. [Selection diagram] Fig. 1

Description

  The present invention relates to a continuously variable transmission.

  Conventional transmissions are complex in structure and operation. For example, in a transmission that changes gears manually, power transmission is switched on and off by a clutch petal during gear shifting, and gears are switched by manual operation of a shift lever. Further, the automatic transmission has a complicated structure.

Overview of name issued

Problems to be solved by the invention

  An object of the present invention is to perform a gear shift by simplifying the structure and eliminating unnecessary operations.

Means for solving the problem

  In order to solve the above-mentioned problem, the continuously variable transmission according to claim 1 injects a high-pressure fluid to the input-side impeller (3) (4) (5) as shown in FIG. In other words, it is a continuously variable transmission that shifts gears at the gear ratio of the input side and the output side. As for the structure, the input side consists of parts integrated with impeller (3) and gear (6) that receive energy, impeller (4) and gear (7), impeller (5) and gear (8), These parts are designed to rotate freely without being fixed. The output gears (9), (10), and (11) are connected to each other, and have a diameter that meshes with the input gears (8), (7), and (6) to be integrated. The input side gears <6> <7> <8> and the output side gears <11> <10> <9> are set from the beginning. Since the input side gear is in a free state, even if the input side gear and the output side gear are set from the beginning, they can be rotated without locking. Using this mechanism, the speed is changed by a combination of gears having different numbers of teeth on the input side and the output side. When increasing the rotation speed, the high-pressure fluid is turned counterclockwise to the impeller (3) (4) (5) by operating the distributor valve (2) -1 shown in FIG. Conversely, when decreasing the rotation speed, the distributor valve "[2] -1" is returned to the impeller [5] [4] [3] to the right. By changing this operation and the pressure of the fluid, the speed can be changed steplessly. By adopting this structure, unnecessary operations during shifting can be eliminated, and the structure can be simplified.

The invention's effect

  The invention described in claim 1 has a simple structure as shown in FIG. The gear shifting operation can be easily performed simply by turning the distributor valve "[2] -1" to each shift. Moreover, since the structure is simple, the weight can be reduced and the cost can be reduced. Further, since the internal combustion engine or the electric motor as a power source for turning the pressurizing pump (1) may be a small horsepower, energy saving is achieved. In terms of function, the rotation speed can be changed by changing the impeller (3), (4), (5), or (5), which transmits the energy while the fluid pressure is constant. Conversely, the rotation speed can be changed up to a certain load by changing the pressure of the fluid without changing the impeller (3) (4) (5) that transmits the energy. With this combination, the speed can be changed steplessly. Also, when increasing the rotation speed, turning the distributor valve "[2] -1" to the left turns the high-pressure fluid to the impeller [3] and releases it to the impeller [4]. The high-pressure fluid does not flow to the impeller (4) at a stroke, and the input side gear and output side gear are set from the beginning, so the impeller that does not receive energy always rotates (each rotation speed). Is different), so there is no knock at the time of shifting and the gear can be shifted smoothly.

Explanation of power transmission method

  The power transmission method is as follows. A high-pressure fluid is generated by the pressurized pump (1) in FIG. 1, sent to the distributor (2), and the high-pressure fluid is supplied to each impeller by the distributor valve (2) -1. Distribute. In the case of shift 1, the impeller (3) → gear (6) → gear (11), in the case of shift 2, the impeller (4) → gear (7) → gear (10), and in the case of shift 3, the impeller (▲) The power is transmitted from the gear 5 to the gear 8 and the gear 9 to change the rotation speed. In order to increase the rotation speed while the fluid pressure is constant, the distributor valve "[2] -1" is turned counterclockwise from the impeller [3] to the impeller [4]. Also, when horsepower is required on the output side, the distributor valve "(2) -1" is returned to the right. At this time, the output side rotation speed decreases. I have to raise it.

  As can be seen from FIG. 1, the input-side impeller and the gears are integrated into a part, and these parts are structured to rotate freely without being fixed. Gears with different diameters are attached to the gears mounted on the impeller. As shown in FIG. 1, the output side gear is set to have a diameter that meshes with the input side gear to be integrated. The input gear and the output gear must be set from the beginning. The number of impellers may be arbitrarily changed according to the number of shifts. Further, as the diameter of the impeller is larger, a larger torque can be obtained with smaller energy. Since the tip of the impeller receives energy, it should be shaped to minimize energy loss.
