Parallel hydrodynamic retarder - Retarder - Qingdao Kelin Intelligent Transmission Automobile Technology Co.,Ltd.

Parallel hydrodynamic retarder Retarder

ASolenoid valve group technology: adopts high-speed switching solenoid valve group digital control technology, solenoid valve with redundant design.
BIntegrated controller: independently designed hydrodynamic retarder integrated RCU, the control system is integrated inside the valve module.
CRadiator: Adopting unique herringbone structure design to realise strong heat dissipation ability, which can support the retarder to work continuously and normally.
DCasting process: The stator and rotor casting process adopts the original automatic block extraction mode to improve the accuracy of the parts.
EFrom product design, production, processing, assembly to control programme development, whole vehicle testing and assembly are all developed independently.
FBased on fluid simulation analysis, the rated braking torque of 3,800Nm-4,200Nm is achieved, which can cover the braking demand under various extreme working conditions.
GThe whole process of product design and development strictly controls the cost, which has a large cost advantage under the premise of ensuring product quality.
HIntelligent control technology is adopted to fully reflect the driving intention and synergise with other braking systems of the whole vehicle to bring out the braking capacity.
IThe product's opening response time, closing response time, power loss and other indicators are better than the national standard requirements by the third-party agency inspection.

HOTLINE

This product provides intelligent transmission systems for heavy commercial vehicles, special engineering vehicles and new energy vehicles.

Constant speed braking function: automatically adjust the braking force according to the change of gradient to ensure that the vehicle goes downhill at a constant speed.
Graded braking function: 4 braking gears are used for graded braking of the whole vehicle.
Combined Braking Function: Combined braking is formed with engine exhaust braking.
ABS co-ordination function: when ABS intervenes, the retarder automatically stops working.
Over-temperature protection function: overloading of the vehicle or other faults cause the retarder oil temperature and water temperature signal to exceed the limit, the retarder will protect itself according to the procedure.
