Hydraulic Retarder - Braking System

Hydraulic Retarder - Braking System

The automobile retarder energizes the excitation coil of the stator assembly through a control circuit to generate a magnetic field. The rotor assembly rotates at high speed with the vehicle transmission part, cutting magnetic lines of force, generating reverse torque, and slowing the vehicle.

In order to adapt to the development of the medium and heavy truck market and meet the auxiliary braking needs of the entire vehicle in terms of safe driving, DARE AUTO began to establish a Hydraulic Retarder product research and development team in the North American R&D Center in 2012 and collect relevant product research and development data. The main members of the team are technical engineer from Europe and North America who has lots of experiences in hydraulic retarder product engineering. It has taken nearly 10 years to develop a hydraulic retarder suitable for matching heavy trucks with the mature research and development experience of European hydraulic retarder products. After nearly a decade of development, it has now been iteratively updated to the second generation of products, at the same level as well-known foreign brands. It has independent intellectual property rights and has applied for 22 patents, including 6 invention patents and 1 appearance patent.

The hydraulic retarder is a hydraulic device that reduces the traveling speed of a vehicle. It is generally composed of the retarder body, control device, electronic control unit, and other components. In the retarder body structure, the rotor and stator jointly constitute a working chamber. When the hydraulic retarder is operating, the electronic control system controls the proportional valve to apply air pressure to the working fluid to fill the working chamber.

The stator is integrated with the retarder housing and connected to the rear end or frame of the transmission. The rotor is connected to the transmission shaft through a hollow shaft, and blades are cast on both the rotor and stator. During operation, pressure is applied to the oil pool through the operation of the control valve to fill the working fluid into the working cavity between the rotor and stator. When the rotor rotates, a torque is applied to the stator through the working fluid, and the reverse torque of the stator becomes the braking torque of the rotor. Its value depends on the amount of fluid and pressure in the working chamber (determined according to the brake strength gear set by the control valve), as well as the rotational speed of the rotor. The kinetic energy of the vehicle is consumed by the friction of the working fluid and the impact on the stator, which is converted into heat energy, causing the temperature of the working fluid to rise. Work is also introduced into the heat exchange cycle flow, which transfers heat to cooling water and dissipates it through the engine cooling system. In vehicles with hydraulic transmission, oil pools, oil pumps, heat exchangers (which need to be enlarged in size), and working fluids that utilize hydraulic transmission can be eliminated. Therefore, hydraulic retarders are mostly used in hydraulic transmission vehicles.

The retarding efficiency is higher than that of the engine retarding device, and it can drive downhill at relatively high speeds; Small size and mass, can be integrated with the transmission; No wear occurs during operation; The heat generated by the working fluid is easily transmitted and dissipated, and can maintain the normal operating temperature of the engine during long downhill runs; When braking at low speeds, the braking torque tends to zero, and the wheels do not slip when braking on slippery roads. The disadvantage is that the coupling and separation lag time is long, and there is power loss when not working. When used in mechanical transmission vehicles, especially in trailers, the structure is complex.
