BRAKE AND LUBRICATIONS

BRAKE AND LUBRICATIONS

                       For any vehicle power production is very important and the way to control it also important well If this power is not controlled in the vehicle, the one who handling the vehicle may land in hazardous situation .Usually in any vehicle the amount of power supplied is governed by the help of clutch which is connected to flywheel. But ass in this project there is no engine and gearbox the power is directly transmitted to the wheel. So this power is controlled with the help of a brake at the rear wheel. The vehicle equips a drum break which contains brake shoes that are pressed against inner surface of the drum. When this happens the drum resists the wheel form rotating and brakes are applied. Drum brakes are often applied to the rear wheels. Since most of the stopping force is generated by the front brakes of the vehicle and therefore the heat generated in the rear significantly less.

                     Lubrications is the process or technique employed to reduce friction between and the wear of one or both, surface in close proximity and moving relative to each other, by interposing a fluid called a lubricant between them. Lubrication is required for correct operation of mechanical system piston, cam, bearing, etc. where without lubrication the pressure between the surfaces in close proximity would generate enough heat for rapid surface damage which in a coarsened condition may literally weld the surface together. In motor piston, firm between the piston and the cylinder wall also seals the combustion chamber, preventing combustion gases from escaping into the crankcase.  

                    Adequate lubrication allows smooth continuous operation reduces the rate of wear and prevent excessive stress or seizures at bearings. When lubrication breaks down components can rub destructively against each other, causing heat, local welding, destructive damage and failure.

                 The use of a lubrication reduces the overall system friction. Reduces friction has the benefit of reducing heat generate and reduces formation of wear particles as well as improved efficiency.

                  Lubrications are typically used to separate moving parts in a system. This has the benefit of reducing friction and surface fatigue, together with reduces heat generation, operating noise and vibrations.
