Product Description

Hydraulic Retarder Technical Overview & Application Guide
(Professional Technical Documentation)

1. Product Overview

The Hydraulic Retarder (also known as a hydrodynamic retarder) is an advanced auxiliary braking system that converts vehicle kinetic energy into thermal energy via fluid dynamics, enabling controlled deceleration without mechanical wear. It is widely used in heavy-duty vehicles and industrial machinery to enhance safety, reduce main brake wear, and improve operational efficiency47.

2. Technical Parameters Table

Parameter	Specification	Notes
Max Braking Torque	3,500-4,500 Nm	Adjustable via oil pressure and flow310
Power Dissipation	Up to 600 kW	Dependent on rotor speed and oil volume5
Operating Temperature	-40°C to +150°C	Integrated cooling system for heat dissipation4
Weight	45-85 kg	Compact design for easy integration3
Fluid Capacity	8-15 L	Compatible with standard hydraulic oils2
Response Time	<0.3 seconds	Instantaneous torque delivery10
Control Interface	CAN bus/Electric proportional valve	Supports seamless vehicle integration3

3. Primary Application Fields

1. Commercial Vehicles
   • Mining Trucks: Controls speed during downhill operations in high-load conditions (e.g., 30-ton dump trucks)57.
   • Long-Distance Buses: Ensures stable braking on mountain roads, reducing driver fatigue3.
2. Industrial Machinery
   • Cranes & Excavators: Provides precise load control during lifting/hoisting operations2.
   • Power Generators: Stabilizes rotational speed in diesel generator sets7.
3. Specialized Transport
   • Tankers & Hazardous Material Carriers: Minimizes fire risks from friction-based braking4.

 

4. Key Advantages

1. High-Efficiency Braking
   • Achieves 80-90% braking force distribution, significantly reducing main brake usage310.
2. Zero Wear & Longevity
   • Non-contact fluid transmission ensures >50,000-hour service life without component replacement47.
3. Thermal Management
   • Dual-cycle cooling (engine coolant + independent radiator) prevents overheating even during prolonged descent5.
4. Safety Enhancement
   • Automatic torque adjustment prevents wheel lockup on slippery surfaces4.
5. Adaptability
   • Compatible with hybrid/electric drivetrains for regenerative braking optimization10
