Features of Koea R series electromagnetic retarder.
1. High efficiency : Braking torque ranges from 1400Newton metres to 900N.M(for example 900N.M, 1200N.M,1400N.M) adaptable for variety of wehicles,bus, van, and automobiles.
2. Low power consumption.
a. Working voltage: 24V
b. Working current: 60Amper, 80A, 85A.
3.Application: Fit the weight ranges from 9 tons~17 Tons for bus, vehicles.
4. Save cost: Lower the possibility of the wear and tear of braking system.
5. Long life: Made of imported original Japan materials, which slight the heat deforming of the two rotor turntables, so the moment declining along with heat declining is light, which can work a long time.
6. Compact Structure and flexible installation in gearbox or rear axle.
7. Digital controlling system ensures driving safety and stability. It will be much safer to drive.
Knowledge of Koea electromagnetic retarder
The Keao Retarder is the vital component at the heart of a remarkably effective driving aid: an integrated braking system.
Fitted to the output end of the gearbox, the unique Keao Retarder provides the means for slowing road speed without constant use of the service brakes or exhaust brake. It is fully integrated with the service brakes and exhaust brake – and also, if fitted, cruise control and Opticruise.
The driver can choose to have complete control over all braking functions without having to actuate each one individually.
The Keao Retarder can be used manually by the driver to control the speed of the truck. It can also be set to operate automatically, according to the driver’s needs. For example, in the fully automatic mode, a quick dab on the brake pedal engages "downhill speed control". This means that the exhaust brake is operated automatically whenever needed, in conjunction
with the retarder, to control the vehicle’s speed.
Use of the Keao Retarder in the fully automatic mode will reduce wear on tyres and will preserve the wheel brakes in a cool, fresh condition for when they are really needed.
