Abstract

Provided is a track car drive system, which is assisted by a generator motor so that it may attain a gear array for equalizing the gear numbers and the gear ratios at the individual gears as a transmission for the forward speed and the backward speed and which can be combined with the generator motor. A transmission (15) for receiving the output of an engine (14) at an input shaft (30) is constituted by combining a forward gear train (31) and a backward gear train (32) with two intermediate shafts (41 and 42) having different speed change gear stages (51 to 54) between themselves and an output shaft (45). By shifting/fastening a first clutch (43) or a second clutch (44) selectively, the rotation of either the forward gear train (31) or the backward gear train (32) is transmitted to either of the intermediate shafts (41 and 42). When one of the speed change gear stages (51 to 54) is selected, the same gear number and gear ratio are taken no matter whether the track car might run forward or backward. The assist force by the generator motor (18) is applied from a differential mechanism (55) through the two intermediate shafts (41 and 42) to the output shaft (45).

Description

technical field [0001] The present invention relates to a drive system for rail vehicles provided with a transmission for shifting and outputting rotational output of an engine, and to a rail vehicle using the same. Background technique [0002] Conventional drive systems for internal combustion locomotives are configured to input the output of an engine such as a diesel engine to a transmission (transmission device) and transmit the output of the transmission to wheels via a drive shaft. In this system, the speed change is carried out through the transmission. On the other hand, as another type of drive system, a system has been proposed in which all the output of the engine is input to the generator, the electric energy output from the generator is input to the inverter, the frequency is converted, and the system equipped on the chassis is electrically driven. motor. Even when the engine is stopped, the electric power from the battery can be used to run the motor. In th...
