T A C N Series
TD C N S e r i e sPower-Shift Transmission For Rail

Transmission for Railway applications
Our transmissions consist of a high-elastic coupling, a torque converter, a two-,
three- or four-speed power-shift-transmission and an advanced electronic control system.

Standard specifications
Our transmission is categorized as “hydromechanical transmission” which combines atorque converter with a wet multiplate clutch. Our standard specifications are as follows.

Introduction of“Hitachi Nico Transmission Co., Ltd.”Torque converter
Torque converter realizes a smooth shockless start of vehicle and increases the torqueat a low speed of vehicle.

Since 1952 when our predecessor company “Niigata converter” started operation, weextensively have contributed to society through our products for mainly Japanese railway

Power-shift-transmission

business. Our products for railways are Power-shift transmission, Final drive gearbox, etc.
for DHMU, DHL, and motor cars by diesel engine drive.

Power-shift-transmission provides forward/reverse shifts and multiple speed steps.
And a direct clutch option is available.

In the history of about 70 years, our products have not only had a high share in the domestic
market but also been sold all over the world(Asia, Oceania, Europe, South America, etc.).

TCU “Transmission Control Units”

We continue efforts to develop the rail industry around the world by supplying our optimal
products in accordance with regional characteristics in its operating areas.

TCU has the functions of an automatical smooth clutch shifting, a monitoring system,
an abnormal alarm, etc.

Our visions
CHALLENGE IS OUR VALUE
Up to now, we have grown by supplying new products to the market. From now on, we willcontinue to challenge to develop new products required in each era too.

You can tailor a transmission by selecting the following options.

Brake function to reduce speed :This function is an auxiliary brake to reduce the vehicle speed while the vehicle is running
downhill in a mountainous area.
Optional device Hydraulic Retarder Brake, Multiple-disc Brake, Engine Brake

The update on our new special products andConstant low speed control :our sales achievements in recent years are as follows.

TCU controls a transmission brake effort to realize a constant low speed of vehicle.
Optional device Multiple-disc Brake

1. Parallel hybrid transmission for Diesel Hydraulic Multiple UnitsWorld' first : we have developed the parallel hybrid transmission for Diesel HydraulicMultiple Units in 2008. This transmission has engine driving mode, motor driving mode,
motor-assisted driving mode and regeneration brake mode. The best fuel efficiency forDiesel Hydraulic Multiple Units is realized by combining several operation modes.

2. Special transmission for Rail-carrier
Various options for our transmissions have been requested to realize an ideal driving forrail-carrier carrying a lot of heavy rails. This transmission has two major options of theconstant low speed system and the retarder brake for running on a long downhill.
As described above, we can produce not only the standard models but also the optimally customized models in accordancewith your requirements. We look forward to hearing your precious suggestions.

Power Take Off (PTO) : Generator, Oil pump and FanPower Take In (PTI) : Oil motor and Electrical motor
Others :- Hybrid (Parallel Hybrid)- Parking Brake- Cut-off-shifter (one-side-output)- Customized design, etc.

Request to Customer
We can challenge new technologies to meet the new needs of customers.
If you have any question, request and/or idea, please contact us.
