The disc brake was introduced to the USA before and in Europe after the center of the last century into mass production. It can work leaving the braking action by overheating (Fading) particularly well against. At the front axle she avoids inclined pulling. The removal of brake lining deaf improves and the assembly is clearly facilitated. Also the braking force differences with pre and reverse movement, habituation-needy with some drum brakes, are fit. On a disk usually from grey cast iron, Kugelgrafitguss, connected with the wheel, steel or from carbon fiber materials pressure more rarely at braking surfaces from the inside and outside.

Since the pliers mechanism is connected with the wheel suspension, the brake disk and thus the wheel are braked. With drive axles the arrangement of the disc brake became completely rare inside at the final drive. One with the mounting connected brake pliers is called firmly brake calipers (pictures above). Here pistons affect from both sides the disk/surfaces. If it is adjustable, then one speaks in the meantime only of a fist saddle (picture left). Older designs are designated also than Schwimmsattel. Here or two pistons influence exclusive from the inside.

The manipulation is usually made with the emergency brake by means of push pull cables and lever (linkage) at the brakes, with the hydraulic foot brake by means of brake fluid printing on one or more pistons and cylinders and with the pneumatic brake by external diaphragm or (again more rarely) piston cylinders. Both with compressed air and with hydraulics one is from the inside possible around the brake disk seizing brake pliers, in order to increase the Reibfläche.

With the disc brake there is no self reinforcement. Therefore e.g. the pistons are in the diameter larger and thus the contact pressures higher. Warmth and dust can be better dissipated by the open building method. Interior/outer ventilation of the brake disk (fig. 1 and 3) increases this effect. To nearly all motorcycles and passenger car foremost and usually also the disc brake seems to rear axles. Only smaller, lighter and economical small vehicles have in the back drum brakes. The spreading of pneumatically actuated disc brakes increases with buses and truck strongly. Even the modern and the fast rail-mounted vehicles avail themselves of these

TRANSMISSION SYSTEM

Transmission systems, in automotive, is a system that became conductor of energy from the engine to the differential and ace. By rotating axles, the wheels can rotate and move the car.Transmission is needed because the combustion engine is commonly used in cars is an internal combustion engine that produces rotation (rotation) between 600 to 6000 rpm. Meanwhile, the wheel rotates at a speed of rotation between 0 to 2500 rpm.

Today, there are two transmission systems are common, namely a manual transmission and automatic transmission. There are also transmission systems which are a combination of both systems, but this is the last new developments can be found on high-tech cars and only certain brands. Manual transmission is one type of transmission is widely used by grounds maintenance easier. Usually on the transmission of the manual consists of 3 to 7 speed.

 Semi-automatic transmission is a transmission that can make us feel the system can be manual or automatic transmission, when we're using a manual transmission system we do not need the clutch because the clutch pedal transmission system is already organized automatically. Automatic transmission consists of three main parts, namely: Torque converter, Planetary gear units, and hydraulic control unit. Torque converter serves as an automatic clutch and the engine can enlarge moment. While the torque converter consists of Pump impeller, turbine runner, and the stator. The stator is located between the impeller and turbine. Torque converter is filled with ATF (Automatic Transmition Fluid). The moment the machine is moved by the fluid flow.

 

Transmission systems, in automotive, is a system that works for the conversion of torque and speed (revolutions) of the engine torque and speed to be different to be forwarded to the final drive. This conversion is changing the high rotational speed becomes lower, but more powerful

Torsi a machine generally occurs in about half of the allowable limit of engine speed, while the vehicles require high torque at start moving. In addition, vehicles that run on roads that climb requires a higher torque than the car that runs on a flat road. Vehicles that run on low speed requires a higher torque than high speed. With the operating conditions are different then the transmission system is needed to power requirements can be met by the machine.

Manual transmission is automotive transmission system that requires its own driver to push / pull like the motorcycle or the clutch as the car and swap the acceleration gear manually. Acceleration of the teeth arranged in the gear box / gerbox for several speeds, typically ranging from 3 gear acceleration forward up to six advanced gear acceleration combined with a reverse gear (R).

 Acceleration of the teeth that is used depends on the speed of the vehicle at low speed or climbing gear used and so that the acceleration of a higher speed, and vice versa if you reduce the speed of acceleration gear down, braking can be helped with a reduction gear acceleration.

RADIATOR

A correctly dimensioned heating element is warmest at the top side, near the entrance valve (advance); at this valve the warmed up medium flows into the heating element inside. The temperature decreases downward, since the warmth carried in the carrier medium was transferred over the heating element by radiation and convection to the area. At the lower surface of the heating element a close offable return screw connection is often installed. From there the cooled down medium is led back over the return pipe to the boiler.

 Often erroneously accepted, a heating element must be evenly kept at a moderate temperature from top to bottom. At the latest since the oil crisis in the 1970's the inlet temperature of the heater (and concomitantly the heating element) as a function of the outside temperature is in most cases adapted. Held in some old plants the inlet temperature constantly high, e.g. 90 or 70 °C. This leads to unnecessary calorific losses - above all, if the outside temperatures are no longer so low. , The radiating surface arranged into the area plays a crucial role for the comfort.

The radiation portion of the heat emission of a heating element is however small with small inlet temperatures in relation to convection. Following English term for heating element (radiator) also in Germany heating elements are often called radiators, although the radiation (radiation) is small. The radiated amount of heat rises strongly with the temperature and is higher with electrical radiant heatings or also with steam-claimant heaters. Thus there are attached heat pipes, which possess additional, downward arranged metal sheet metal reflectors in workshops occasionally under the cover, in order to increase the portion of the radiant heat.

In former times above all heating elements from grey cast iron were common; these had - compared to the modern flat heating elements used nowadays - a smaller surface as well as a very high dead weight, were however very corrosion resistant for it. While the time of the national socialism became, in order to withdraw from the armaments industry no ferrous metals, radiators from porcelain offered. These could not become generally accepted however.

In the GDR the idea, and for instance in the middle of the 1950er was again taken up years heating elements from porcelain in 4er or 5er rib blocks were manufactured off. There were in principle two execution variants: flanged and spindled. Here the kind of joining the blocks is meant to the finished heating element. The employment of the porcelain heating elements preferably took place in public buildings such as hospitals, boardings school etc., isolated also in housebuilding. Also mobile electrical radiator heating elements from the porcelain blocks were manufactured by different enterprises. Starting from beginning of the 1960er years the production of porcelain radiators was stopped. 

 

For the up-to-date most usual design the serrated construction is characteristic for the 1960er years from work-hardened and roll-welded steel sheets; thus large surfaces are obtained. In such a way manufactured heating elements are painted or powder-coated. Besides increased also heating elements from steel tube are used; in the sanitary area this design becomes special from practical (towel dryer) and aesthetic reasons preferred. Current heating elements are in different versions (kind of the connections, length, width) and also colors available and after the assembly immediately operational.

 Special forms represent floor and wall heatings as well as cover radiant panels. Here the surfaces of the walls, floors or floor slabs provided with pipes or electrical heating wires serve as wide heating elements.
