Vehicle test stands

Roll test bed for vehicles with DC dynamometers

TYPE: "4VDM E120"

Use:

Roll test bed with DC dynamometers for vehicles represents a modern measuring device for testing of power and brakes of private and utility cars up to power of 240 kW on each axle, up to speed of 200 km/h. The use of DC dynamometers of each roll (vehicle wheel) and electrically controlled clutches enable to configure the test-room according to the required test and to make autocalibration the test-stand, or calibration with a vehicle. With respect to integrated inertial mass (defined) it enables to make static and dynamic tests.

Basic parameters
Max. test speed	200 km/hour
Max. axle load	2000 kg
Roll diameter	1,2 m
Roll width	600 mm
Clearance between rolls	900 mm
Roll mass of inertia – each axle	1130 kg

Roll test bed with DC dynamometers for testing of power and breaks:

• Tractors

• Lorries type VDU E270 + VDU E150

Use:

Roll test bed with DC dynamometers for vehicles is a modern measuring device for testing of power and brakes of tractors with power up to 270kW on rear axle and 150kW on front axle and for speed up to 16 km/h. The use of DC dynamometer on each roll (vehicle wheel) and electrically controlled clutches enables to configure the test-stand according to required test and to make autocalibration or calibration with a tractor. The test-stand is designated to make static tests and also to load tractor via rear shaft by means of an eddy-current dynamometer.
