A Novel Parallel Twin Turbine Drive Compound Transmission

technical field

The utility model relates to a novel parallel twin-turbine driven compound transmission device.

Background technique

At present, the main power transmission mode in this field is shown in Figure 1: the power is input by the input shaft 1.1, and it is transmitted in three parts through the gear transmission. The gear pair composed of 1.19 is absorbed, the second part of the power is transmitted to the starting motor drive component composed of the starting motor drive gear 1.21 and the starting motor drive shaft 1.20, and the third part of the power is transmitted to the cooling fan drive shaft 1.22 and the cooling fan drive gear pair 1.23 Composition of cooling fan drive components. The input speed-up gear is rigidly connected to the driven gear 1.18 and the pump wheel shaft 1.15. At this time, the pump wheels of the starting torque converter 1.9 and the operating torque converter 1.17 rotate synchronously with the pump wheel shaft, and the gears are driven by the first charging pump The driving part of the charging pump composed of pair 1.10, charging pump 1.11, and the second charging pump driving gear pair 1.12 obtains a part of the power transmitted from the pump wheel shaft to make the charging pump 1.11 work, and press continuous working oil into the starting transformer. torque converter or running torque converter. The torque converter drives the serial number turbine shaft 1.16 through the principle of energy conversion, and the power output by the turbine shaft passes through the first rotation conversion gear 1.2, the reverse output gear to the driving gear 1.3, the second rotation conversion gear 1.4, and the forward output The gear transmission mechanism composed of the gear pair driving gear 1.6, the first output shaft 1.7, the forward and reverse output gear pair driven gear 1.8, and the second output shaft 1.14 outputs power. Mechanism 1.5 to change the rotation direction of the first output shaft 1.7 and the second output shaft 1.14.

With the continuous development of internal combustion rail locomotives, the demand for high speed, high efficiency, and high comfort is becoming increasingly urgent. The existing hydraulic transmission box technology can no longer reflect the requirements of "high speed, high efficiency, and high comfort". The hydraulic transmission box mainly has the following disadvantages: the existing hydraulic transmission box is not efficient at high speed. The high-speed gear (running torque converter) adopts the traditional torque converter form, and the efficiency in the high-speed area is not high, and as the operating speed increases, the efficiency decreases, the fuel consumption is large, and the operating cost is high. The existing hydraulic transmission box is poor in comfort. Due to the complex structure of the transmission box, which integrates two components of power, and due to the arrangement of the input shaft and the output shaft (up and down), the size of the transmission box in the height and width directions is relatively large. So large that when arranging the power system of the whole vehicle, the upper part of the engine and transmission box must be placed above the working plane of the locomotive, resulting in excessive noise and vibration of the whole vehicle.
