General instructions

About the manual

This manual contains the technical instructions for the Black Bruin On-Demand Drive

System that uses CVM120/CVU200 valves and CTR101/CTR201 control systems.

Obey these instructions when you plan to use the products.

All information is based on information that was available at the time that this manual

was written. The manufacturer reserves the right to change the content of this

manual without further notice.

Please visit www.blackbruin.com for the most recent version of this manual. The

product datasheets and the 3D-models are available from the manufacturer by

request.

The operation instructions of CTR101/CTR201 control systems are in the operation

manuals:

• CTR101 control system Operation manual

• CTR201 control system Operation manual.

Note:

If there are dierences between the English text and its translation, the

English text is always the most accurate. This document is written in

Simplied Technical English (ASD-STE100).

Intended use

The CVM120/CVU200 valves and the CTR101/CTR201 control systems are part of the

Black Bruin On-Demand Drive System.

Black Bruin On-Demand Drive System is a transmission solution for tractor-driven

trailers and working equipment.

Black Bruin On-Demand Drive System is very applicable for equipment that

periodically requires additional power and is towed without hydraulics.

Black Bruin On-Demand Drive System is designed for o-road driving and must be

powered o when you drive in road trac.

Danger:

Make sure that you power o the system when you drive on road.

These products are only applicable to use together with the freewheeling Black Bruin

motors. The valves and the control systems are specially made for transmission

solutions with B200 series 2-speed motors. Please contact the manufacturer or their

representative who will help you to select the most applicable motor model for your

application.

The components of the On-Demand Drive System make driving functions easy to do.

The manufacturer of the nal product is responsible for the manufacture of the

machine and that the product is correct for the application it is specially made for.

Main components of the On-Demand Drive System

1Valve

• Motor mode changes between driving and freewheeling

• Driving direction change

• Displacement control of two-speed motors

• Pressure level (tractive power) adjustment

• Assisting traction control (ATC)

• Hill descent control (HDC) function (in selected models).

2Hydraulic motor

• Wheel hub motor

• No pressure required in freewheeling mode

• More extensive driving speed range with inbuilt two-speed valve.

3Control device

• Controls the system functions

• Controls the valve

• Measures the pressure from the system’s pressure sensors

• Monitors the brake signal

• Monitors the external alarm signal (optional)

• Controls the application specic auxiliary valve (optional)

• Stores the system settings

• Collects the speed and direction information via tractor's ISOBUS

implement socket (CTR201).

4Display

• The system control element

• Shows information to the user about the operation of the system

• Many alternative languages.

Control systems

The two control systems, CTR101 and CTR201, have functions to control the driving

mode in 2WD and 4WD applications.

CTR101 control system is applicable to all tractors. It provides driving functions that

you can activate with the system display. It can also automatically switch the system

to freewheeling mode if the working pressure drops due to increased driving speed.

CTR201 control system is applicable to tractors that have the ISOBUS implement

connector. It has automatic functions that use the tractor's speed and direction

information to make the operator’s work easier. If necessary, manual operation of the

system is also available.

Working principle

The Black Bruin On-Demand Drive System can use hydraulic motors in the operating

modes that follow:

• Driving mode

• Driving mode with HDC function (Hill descent control) (option)

• Freewheeling mode.

The chapters that follow give the working principles of these modes.

Driving mode

In this mode the motors help the vehicle to move in the direction of travel. You can

adjust the tractive power level to the driving conditions. The power level stays

constant also if the speed changes. When the tractor brakes the system reduces the

working pressure to the minimum level and the hydraulic motors do not have tractive

power.

2-speed hydraulic motors give wider speed range for the hydraulic drive.

If the vehicle wheels slip, the assisting traction control ATC increases the torque on

the wheels that have more traction.

Typical situations to operate in the driving mode are:

• Driving up steep slopes

• Moving rearward on steep slopes

Product description

8 Product manual

• Going across obstacles

• Driving on slippery or soft surfaces.

HDC function (Hill descent control) (option)

The HDC function helps when you drive the vehicle down on steep slopes, in both

forward and reverse driving modes.

When the HDC function is active, the wheel motors resist the wheel movement to the

driving direction. You can adjust the HDC power level during the operation.

Typical situations for the use of the HDC function are:

• Driving down steep slopes

HDC function o, vehicle accelerates.

• Driving down steep slopes

HDC function on, function helps the

vehicle to maintain the speed.

• Moving rearward on steep slopes

HDC function o, vehicle accelerates.

• Moving rearward on steep slopes

HDC function on, function helps the

vehicle to maintain the speed.

Product manual 9

Freewheeling mode

In the freewheeling mode you can freewheel the motors without energy loss or

overheating problems (stationary cylinder block - no centrifugal forces), even at high

speeds. You can engage the drive again during movement when the speed is in the

working range.

If the pressure level is not sucient due to increased driving speed, the control

system automatically switches to freewheeling. This protects the motor from

overloading.

The operator can also manually change the mode to freewheeling.

Typical situations to operate in the freewheeling mode are:

•When you drive on road

• When you do work above the maximum working speed range

• When the working conditions are easy.
