Disadvantages: it is large in size, heavy in body, consumes electric energy and is greatly affected by ambient temperature. At present, it is only applicable to large commercial vehicles

Hydraulic turbine retarder: a turbine chamber is added at the rear end of the gearbox housing. When the braking circuit is turned on, the transmission oil will generate damping in the turbine to achieve the braking effect. There is no wear, but the heat dissipation should be increased. At present, ZF gearbox is used on high-end passenger cars.

Retarder is an electromagnetic device installed on the transmission shaft of the vehicle. During use, the electromagnetic device generates a force opposite to the rotation direction of the transmission shaft. It is generally used in large vehicles. The advantage is that the vehicle speed can be properly reduced when the vehicle braking system is not working, so as to prolong the service life of the braking system. The disadvantage is that the vehicle cannot be completely parked.

Advantages: high braking efficiency. In addition to stabilizing the vehicle speed, it can also reduce the temperature of the wheel brake, improve the service life of the friction plate, and improve the safety and smoothness of the vehicle.

The principle of the eddy current retarder is the same as that of the generator. There is a stator coil on the transmission shaft and a rotor coil fixed on the beam to surround the transmission shaft (but the shape is very different from that of the generator). Computer control is not required. As long as the circuit of the coil is connected, the retarder will produce resistance to the transmission shaft.

The retarder is used as an auxiliary device of the braking system. It is mainly used for passenger cars with a capacity of more than 5 tons and trucks with a capacity of 12 tons or goods. When the car is decelerating or going down a long slope, the retarder can be used to decelerate smoothly and avoid the wear and heat caused by using the brake. For vehicles that often drive in mountainous or hilly areas, to continuously reduce or maintain a stable speed and reduce or release the load of the service brake for a long time when going down a long slope.

According to different action forms of braking torque, it can also be divided into primary retarder (acting on the front end of the transmission) and secondary retarder (acting on the rear end of the transmission).

Disadvantages: long delay time of engagement and separation, power loss when not working, and complex structure when used in mechanical transmission vehicles, especially in trailers.

Advantages: the retarding efficiency is higher than that of the engine retarding device, and it can drive downhill at a relatively high speed; Small size and mass, can be integrated with the transmission; No wear during operation; The heat generated by the working fluid is easy to be transmitted and eliminated, and the normal operating temperature of the engine can be maintained during long downhill; The braking torque tends to zero at low speed, and the wheel will not slip during sliding braking.

Electric turbine retarder: it is equivalent to installing a "generator" on the transmission shaft. When there is no power supply, there is no contact or wear. When braking is required, connect the electric retarder (2 pieces) circuit, and the transmission shaft will be subject to the resistance of electromagnetic field to achieve the purpose of braking. No wear but large structure. At present, there are many heavy trucks and large passenger cars (in foreign countries, the battery can be charged while working).

Sapphire and Ruby Ball Lenses are both made from Al203. Ruby or Ruby-Doped sapphire owes its red color to traces of chromium oxide (chromium content for ruby balls is typically >0.5%). While their physical and chemical properties are similar, Sapphire has superior optical transmission. Ruby Ball Lenses are easier to see and handle for physical applications. Sapphire and Ruby Ball Lenses are ideal for improving signal coupling between fibers, emitters, and detectors. They are also used in endoscopy, bar code scanning, ball pre-forms for aspheric lenses, and sensor applications. Sapphire and Ruby Half-Ball Lenses are also available.
