Product Descriptions

The heart of our transmission technology is the result of over 30 years of continuous on-going NASCAR racing development by one of its premier transmission suppliers.

Medium & Heavy Duty EVT's

EVT2-R High RPM, heavy Duty Two Speed

IEdrives’ EVT2-R can be configured for either high rpm for low to medium torque motors or for high torque, low speed motors. Either configuration is a heavy duty transmission with helical cut gears, capable of high, sustained input speeds up to 9,000 rpm for 30 minutes. This AMT is capable of a continuous peak input torque of up to 1,200 Nm at the lower rpms, and up to 300 Nm at 9,000 rpm. This transmission further offers a very wide range of gear ratio choices for both 1st, and 2nd gear.

The EVT2-R can be electrically shifted with 12Vdc or an optional 24Vdc. A 3-wire RPM sensor on the output shaft is included.

This transmission is specifically designed to be integrated with and controlled by a VCU (vehicle control unit). This AMT is not intended to be manually shifted or manually commanded to shift without the aid of a VCU.

EVT2-RHT High Torque, Heavy Duty Two Speed

IEdrives’ EVT2-RHT is a heavy duty two speed transmission capable of high, sustained input torque up to 3000 Nm up from 0 to 1,000 rpm, and up to 1500 Nm to 2,000 rpm. Maximum continuous input rpm is 5,000 rpm. This transmission is available with ground spur gears which may be required for certain applications. As with the high rpm EVT2-R, the HT version is offered with a wide range of gear ratio choices for both 1st, and 2nd gear.

The EVT2-RHT series can be either electrically shifted with12V or an optional 24Vdc shifter. A 3-wire RPM sensor on the output shaft is included.

This transmission is specifically designed to be integrated with and controlled by a VCU (vehicle control unit). This AMT is not intended to be manually shifted or manually commanded to shift without the aid of a VCU.

EVT4 Medium Duty Four Speed

IEdrives’ EVT4 medium duty transmission is capable of high, sustained input speeds common with many traction motors. The EVT4 with ground spur gears is capable of a continuous peak input torque up to 1250 Nm at the lower rpms, and up to 650 Nm at 9,000 rpm for 30 minutes. Helical gears are available. This transmission series further offers a very wide range of gear ratio choices for 1st, 2nd and 3rd gear. Fourth gear is always 1:1.

This transmission is specifically designed to be integrated with and controlled by a VCU (vehicle control unit). This AMT is not intended to be manually shifted or manually commanded to shift without the aid of a VCU.

Fixed Reducers and Generator Overdrives

IEdrives offers a family of fixed reducers for medium and heavy duty vehicle applications. All of IEdrives reducers can be operated in either direction of rotation, allowing for our reducers to become a speed increasing gearbox. This capability can be beneficial for allowing low speed engines to drive high speed generators. As with the EVT2 multiple speed transmission, IEdrives offers a high rpm configured reducer, and a high torque capable reducer.

EVT1 High RPM Heavy Duty RPM Reducer

IEdrives’ EVT1 is a double reduction gearset, designed for heavy duty vehicle applications. As with all of IEdrives EVTs, it has a female input to allow for close, compact integration with the drive motor. It offers a very wide range of ground helical gear ratios from 4.0 down to 1.1:1. All of these ratios are capable of being driven at high, sustained input speeds. It is capable of a continuous peak input torque up to 1300 Nm at the lower rpms, and up to 350 Nm at 9,000 rpm for 30 minutes. Input torques can be increased with a ground spur gear configuration.

EVT1-hT High Torque Heavy Duty RPM Reducer

IEdrives EVT1-HT would the the high torque version of the EVT1. It has a similar 4.0:1 to 1.1:1 gear reduction range. It has a similar input capability as the EVT2-RHT above

EVT1-SR Single Reduction, Medium Duty RPM Reducer

IEdrives’ EVT1-SR has a single reduction gear set. This is a lighter duty reducer with a decreased continuous input of 200 kW or less. Oil cooling would be required under continuous loading at elevated rpm. The SR variant can provide rpm reduction, or rpm step up, over the range of 2.5:1 down to 1.1:1

YOU HAVE OPTIONS

Options For
all IEdrives' Transmissions

Input Shaft

IEdrives can provide an adaptor to match any motor output to IEdrives transmission input. For splined motor shaft diameters of 1.5 inch (40 mm) or less. IEdrives can offer direct coupling of motor output shaft to the female IEdrives input spline. Contact IEdrives for more information.

Bell Housing or Mounting Plate

IEdrives provides design and fabrication of bell housing or mounting plate as necessary.

Bell housing

A bell housing is required when an input shaft adaptor connects motor shaft to transmission. This adds 3-4 inches to total installed length depending upon motor shaft length.

Adaptor plate

A simple adaptor plate can be used when direct motor to transmission connection is possible. This adds less than 1 inch to the motor/transmission length.

Output Shaft

IEdrives can provide nearly any common automotive driveshaft spline as a no cost “off-the-shelf” option. For all others, IEdrives can match the spline. IEdrives can also provide adapters and matching End Yokes or Flange Yokes any Spicer 1330 thru 1710 series U-joints, or ISO 8667 Type T cross-hatch connections. These compact adapters allow standard bolt on driveshaft attachments to any of IEdrives’ transmissions. Alternative, customer specified, terminations can be provided.
