WHEELS

By -


They are like shining wings..sparkling jewels..the ultimate expression of an automobile...emotions and impressions are focused on them..their light alloy material is seductive..WHEELS are the finest feature of any car.






Wheel is the part that enables efficient movement on a surface where there is a force pressing it to the surface.


CONSTRUCTION

  • Rim       -- It is the outer edge of the wheel which encases the disc and the hub.It is designed to hold tire in position.
  • Hub       -- It is the center of a wheel and houses a bearing and the brake disc.
  • Spokes -- these are the radiating outwards from the hub to the rim. They help in weight reduction, aerodynamics and temperature regulation. 

 The production process begins with fully automatic low pressure casting machines where aluminium alloy (eg. Al-10Si-0.6Cu) is made into an initial shape and a billet is forged using hot forging.Then "Flow Forming" is done in which re-heated wheel is spun and pressed by simultaneous spinning contours giving a proper shape to the wheel.It is then machined to proper dimensions.Heat treatment is done on wheels to give the aluminium structure required strength.Now de-burring is done and bolt holes, valve holes, and the center bore are so drilled in an automatic CNC machine.Then testing is done using infrared testing machines, eddy current testing etc. for any cracks or holes. Now the forged spokes and flow formed rims are fastened together by using titanium bolts.Now the wheel is about to be ready to roll after going through a series of high performance testing machines which test the wheels in extreme conditions so that the quality is uncompromised.



RIM NOMENCLATURE

A) Wheel: Wheel is generally composed of rim and disc.
B) Rim: This is a part where the tire is installed.
C) Disc: This is a part of the rim where it is fixed to the axle hub.
D) Offset: This is a distance between wheel mounting surface where it is bolted to hub and the centerline of rim.
E) Flange: The flange is a part of rim which holds the both beads of the tire.
F) Bead Seat: Bead seat comes in contact with the bead face and is a part of rim which holds the tire in a radial direction.
G) Hump: It is bump what was put on the bead seat for the bead to prevent the tire from sliding off the rim while the vehicle is moving.
H) Well: This is a part of rim with depth and width to facilitate tire mounting and removal from the rim.

                                       DRUM BRAKE                         PRINCIPLE  OF OPERATION- principle of operation of drum brake part-1 principle of operation of drum brake part-2 DRUM BRAKE COMPONENTS- Modern drum brakes are sometimes called internal expanding brakes, since the brake components are internal (inside a drum), and the shoes must expand, or move out­ward, to contact the drum. Drum brake components vary only slightly between manufacturers. Most design differ­ences are in the methods of brake shoe anchoring and spring placement. Backing Plate - To provide a foundation for the drum brake COMPONENTS  and to act as a splash shield against water and road  debris, a backing plate (sometimes call ed a support plate)  is used. The wheel cylinder,brake shoes, and springs are  attached to the backing plate. The flat spots on the backing plate  are cal led support pads.  The wheel cylinder is usually solidly attached to the  top o

Clutch

Clutch The clutch is housed between the engine and transmission where it provides a mechanical coupling between the flywheel and the transmission input shaft.The main purpose of the clutch is to disengage the engine from the drive line while changing gears or starting from rest,however, there are other requirements too. REQUIREMENTS: (1) Pick up load smoothly. (2) Have a driven disc of low moment        of inertia for quick shifting. (3) Damp vibrations of crankshaft. ($) Require little pressure to operate. (5) Be easy to access. (6) Be cheap to manufacture. Now, Mechanical clutches fall in two main categories positive engagement and progressive engagement . The former is either positively disengaged, so that no torque can be transmitted from the driving to the driven shaft, or positively engaged, in which case the shafts rotate together, connected by some mechanical devices such as splines, keys or dogs. In contrast, the progressive type is gradually e

Types Of Mechanical Transmission Systems

Most mechanical transmission fall in three basic categories with three elements each, namely- (1) Clutch, Gearbox and Live Axle, (2) Clutch, Gearbox and Dead Axle, (3) Clutch, Gearbox and Axle-less transmission Clutch, Gearbox and Live Axle --> The engine is in the front with its crankshaft parallel to the axis of vehicle.The drive is transmitted from engine through a clutch and a short shaft 'c' to the gearbox ('c' is almost always integral with the primary gear in gearbox, but sometimes is a separate component with universal joints).From the gearbox the "Propeller Shaft"-having U joints at both ends and a sliding joint at front end-takes the drive to rear live axle.Live axle is the one through which the drive is transmitted while a dead axle is the one through which the drive is not transmitted.Bevel or worm gearing (g) within the axle turns the drive through  90°, and differential gears divide it equally between the two drive shafts, or  ha
