Description

Revolving speed change mechanism

This creation belongs to the technical field of shifting, specifically referring to a revolving shifting mechanism with a simple structure, which can quickly establish power transmission to improve transmission efficiency and make shifting more reliable and reliable.

According to the power transmission of general motor equipment, the output of the driving source is transmitted to the output shaft to provide the driving force of the passive parts, such as the motor (drive source) and wheels (passive parts) of common motor vehicles, and the transmission mainly uses the driving source and The combination of gears with different diameters between the passive parts forms different gear ratios to achieve the purpose of shifting. As far as the existing electric locomotive is concerned, its power source is mainly from the electric motor. Generally speaking, when driving at low speed, the motor speed is better to maintain the efficiency of 1000～2000rpm, but when the electric locomotive has high-speed driving demand, the motor speed will be lower. Increase to higher than 2000rpm, but this will reduce the performance of the motor, so the best way to deal with it is to use the transmission to maintain the motor at 1000～2000rpm, and increase the speed of the passive part driven by the output shaft to more than 2000rpm;

The existing transmissions mainly come in two types. One is a gear transmission, which has better power connection efficiency, but its structure is complex, not only costly, but also difficult to maintain. At the same time, it is easy to be short when switching gears. A sense of frustration caused by speed increase or decrease within time. The second is the Continuously Variable Transmission (CVT), which can simplify the structure, reduce costs and facilitate maintenance, but its power connection efficiency is not good;

Recently, a clutch-type transmission has been additionally developed, which is mainly equipped with at least two clutches on the output shaft to actuate the transmission wheels with different gear ratios to drive the passive parts. Each of the aforementioned clutches is composed of a clutch part and a brake part that can actuate the clutch part. The clutch part is formed by overlapping a plurality of clamps connected to the output shaft and a plurality of connecting transmission wheels at intervals, and is actuated by the brake part. These clamps are tightly combined or separated to achieve the above-mentioned interlocking action, such as the "transmission mechanism" of my country Patent Application No. 105129500, the "Clutch Device of Continuously Variable Transmission" No. 106114229 and the "One Kind of Internal Gear" of No. 107104155 Three-speed dual-clutch transmission" etc.;

However, the above-mentioned existing transmissions that use the clutch method to change gears require electrical components and wires inside the clutch. Therefore, the structure is complicated, and the overall width and volume of the clutch become larger. Furthermore, the power of the clutch mainly comes from the electromagnetic force, which makes the stationary parts When combined with rotating parts, friction is used to achieve this. Therefore, the large dynamic loss causes the problem of difficulty in establishing power transmission. In addition, there will be a discontinuous window period during shifting, and it is further prone to frustration during shifting. Sensation, and reduce the practicality of the transmission.

In other words, the existing transmissions have problems such as too complex structure, increased difficulty in maintenance or replacement, difficulty in establishing power transmission, and poor transmission efficiency, resulting in insufficient reliability in actual use of the existing transmissions, so how to solve the aforementioned problems , Is what the industry and users expect, and is also what this creation wants to explore.

Therefore, the main purpose of this creation is to provide a revolving speed change mechanism, whereby the structure can be effectively simplified, the cost and failure rate can be effectively reduced, and maintenance and replacement can be facilitated.

In addition, the second main purpose of this creation is to provide a revolving speed change mechanism that can directly connect the power during speed change to speed up the speed of the speed change without generating dynamic loss, so it can improve the efficiency and reliability of the speed change.

Furthermore, another main purpose of this creation is to provide a revolving speed change mechanism that can directly change speed without causing the frustration of speed change, so as to improve the smoothness of speed change.

Based on this, this creation is mainly through the following technical means to achieve the aforementioned purposes and effects, which include:

Diameter tooth part and a large diameter tooth part meshing with the speed-up gear;

As a result, at low speeds, the rotational speed wheel set of the speed-up module can be rotated under the revolution, and the input power system drives the output shaft through the driving wheel in one direction. At high speeds, the embedding group is used to stop the relative rotational speed. The revolution of the wheel set makes the shift gear of the relative-rotation speed wheel set can be rotated by the revolution corresponding to the speed-up gear to form a speed-up gear.
