Conventional service brakes have not been able to meet increasing demand on . Deceleration test at high speed is also used for engine brake performance. Retarders are designed to provide auxiliary slowing of the vehicle, such as for controlling the Engine retarders (also known as engine brakes) help to save the main All modern trucks are manufactured to meet safety standards, including. Some Telma retarder models of the Axial series have been especially designed to best meet the specific requirements of test bench integration, such as engine.

Turbocharger retarders that restrict the flow of exhaust gas can also help in increasing the exhaust pressure to achieve the same objective. The retarding horsepower available from this system is significantly lower than other systems. There are several different types which can use standard transmission fluid gear oila separate oil supply, water, or a mix of oil and magnetic retardation.

A simple retarder uses vanes attached to a transmission driveshaft between the clutch and roadwheels. They can also be driven separately via gears off a driveshaft.

The vanes are enclosed in a static chamber with small clearances to the chamber's walls which will also be vanedas in an automatic transmission. When retardation is required, fluid oil or water is pumped into the chamber, and the viscous drag induced will slow the vehicle.

The working fluid will heat, and is usually circulated through a cooling system. The degree of retardation can be varied by adjusting the fill level of the chamber.

Hydraulic retarders are extremely quiet, often inaudible over the sound of a running engine, and are especially quiet in operation compared to engine brakes.

Eddy current brake Electric retarders use electromagnetic induction to provide a retardation force.

An electric retardation unit can be placed on an axletransmissionor driveline and consists of a rotor attached to the axle, transmission, or driveline—and a stator securely attached to the vehicle chassis. There are no contact surfaces between the rotor and stator, and no working fluid.

When retardation is required, the electrical windings in the stator receive power from the vehicle battery, producing a magnetic field through which the rotor moves.

This induces eddy currents in the rotor, which produces an opposing magnetic field to the stator. The opposing magnetic fields slows the rotor, and hence the axle, transmission or driveshaft to which it is attached.

Retarder (mechanical engineering)

The rotor incorporates internal vanes like a ventilated brake disk to provide its own air coolingso no load is placed on the vehicle's engine cooling system. The operation of the system is extremely quiet. A hybrid vehicle drivetrain uses electrical retardation to assist the mechanical brakes, while recycling the energy.

The electric traction motor acts as a generator to charge the battery. The power stored in the battery is available to help the vehicle accelerate. Sixty percent of these truck accidents are collisions. It is always too late when one says, "If only the brakes had worked better. It promises an even higher class of safety and comfort.

Characteristics The world's smallest and lightest, and easy to install Non-contact brakes make troublesome maintenance unnecessary Virtually no power consumption compared with electromagnetic retarders High praise from users "Once you've tried it, you can't drive a truck without it.

Do you think that retarders are expensive and troublesome? Do you think they are difficult to maintain? The permanent magnet type is radically different -- a breakthrough over traditional retarders. So what's the secret? In addition, the brake lining is kept cool, which allows for full braking response in an emergency, giving the driver a greater sense of security.

Simply set the lever once and drive as normal. It works strongly but also softly, which means no concern about your load shifting.

This greatly contributes to less driver fatigue. It's true that traditional retarders had annoying problems like retarder coil burnout and oil leaks, and periodic oil changes were an extra job. However, the Neotard Retarder requires no maintenance at all. And, thanks to its simple construction, there is no need to worry about failure. As a result, the brake lining wear also slows down dramatically. As much as 6-times longer lining life can be expected.

Uneven tire wear is also reduced, meaning a longer life for your tires. In this way, your investment will be returned before you know it. The data itself proves the safety and economy performance. It should be considered only as an example, and none of the figures should be considered a guarantee.
