BODY SHOP

DEFINATION: (BODY)n wheeled or tracked vehicles, body roll is a reference to the load transfer of a vehicle towards the outside of a turn. When a vehicle is fitted with a suspension package, it works to keep the wheels or tracks in contact with the road, providing grip for the driver of vehicle to control its direction. This suspension is compliant to some degree, allowing the vehicle body, which sits upon the suspension, to lean in the direction of the perceived centrifugal force acting upon the car. Anti-roll bars are a part of the suspension specifically designed to address body roll.When a vehicle is fitted with a suspension there is compliance between the mass of the vehicle and the vehicle's contact with the ground. Body roll is the noticeable (either perceived or measurable) deflection produced when load transfer acts on the compliant elements of the suspension. Anti-roll bars directly impact body roll but their design intent is actually as a tool to adjust roll couple percentage or roll moment distribution.

There are mainly three lines in body shop: TRAVELLERTRAXL-CABFORCE ONE chessis also assembled

ST NO.7> Final inspection: inspect whole body to avoid physically ,structural error and Convey to paint shop.

CHASSIS LINE:Definition Chassis Frame Construction Chassis Strengthening and Crossmembers Nuts Bolts and Fasteners TRAX CHESSISFORCE ONE CHESSIS

DEFINITION:-

All Street Rods must have a chassis. A chassis is defined as a structural unit that will support the full load of the vehicle drive train, body and all ancillary components. The body and chassis are detachable by means of standard fasteners and the chassis must not rely on the body for strength. A number that identifies the chassis must be stamped on the chassis. 2.1.2 A Street Rod chassis needs to be a platform that resists twisting. A torsionally rigid chassis will not only be stronger and last longer, but will also provide better handling and allow closer fit-up of body panels. So Chassis is a main structure of the vehicle on which majar component are mounted which necessary to propel the vehicle.

CHASSIS FRAME CONSTRUCTION :-

1. The minimum requirement for a chassis that will support a light bodied vehicle (T-Bucket, Anglia etc) is 75 x 50 x 3mm rectangular hollow section (RHS) mild steel. 2 .The minimum requirement for a chassis that will support heavier vehicles, such as an A model or later Ford, is 100 x 50 x 3mm RHS steel tubing, or tubing of a cross section no less than the original production chassis. 3 .Space frame and other chassis designs are permitted provided that an engineers report is produced if requested by the Examiner. Where there is any concern about the strength or integrity of a chassis, the Examiner may request an engineers report addressing the concern. 4 .All Street Rods must be fitted with a tailshaft loop to contain the tailshaft in the event of front yoke failure. A tailsha ft loop should be positioned no more than 150mm from the front yoke and be constructed so that it will withstand the force of a errant tailshaft that has broken free. The tailshaft loop may be formed as part of the centre crossmember. 5 .Chassis stepped in at the rear to accommodate wheel rims wider than 10 are not permitted.

CHASSIS STRENGTHENING AND CROSSMEMBERS :-

1.he addition of partial or full boxing, lamination of side rails, and the addition of space frame attachments are all suitable means of chassis side rail strength improvement. Full length boxing is highly recommended on all C-section chassis. An Engineers report may be required if a C-section chassis is not boxed. 2. The modification of an early model chassis often includes the full or partial removal of original crossmembers. The minimum requirement after removal of an original crossmember is to install a K member. 3 .All crossmembers must have a minimum wall thickness of 3mm with an appropriate cross-section. The preferred size is 75 x 50mm RHS if one layer is used, or 50 x 25mm or round tube of at least 37mm diameter if two layers are used with ties between the upper and lower layer in appropriate locations. 4 .Chassis crossmembers for engine and drivetrain location may be removable if desired. Ensure that flange plates and bolts used are suitably sized, and that nuts or threaded bosses have enough thread depth for the application. 5 .Any centre crossmember needs to tie together both side rails to ensure torsional rigidity.Refer to the diagrams at the end of the section to ensure that your chassis will be sufficiently rigid. Vintage chassis were not designed as a rigid platform and allowed the chassis and body to flex independently. This is undesirable in a street rod as damage to paint finishes will result from flexing, and ride comfort and safety will be reduced. 6 .Spacer tubes, crush tubes, or stepped bolts must be used wherever a bolt passes through a hollow section of the chassis. The tube should be 3mm or larger wall thickness and welded in position.

NUTS BOLTS AND FASTENERS:-

1. Tabled below are the minimum standards acceptable for the choice of nuts and bolts used in Street Rods. 1.1 Ungraded bolts - Panel fixing,floor panel fixing, and lightly loaded brackets. 1.2 Grade 3 bolts - Seat belts. 1.3 Grade 5 bolts - Moderately loaded members, suspension mounts, crossmembers and tailshafts. 1.4 Grade 8 bolts - Brake callipers, master and slave cylinder mounts, steering arms and all heavily loaded assemblies. Note that high grade bolts are not to be used as seat belt bolts. It is a requirement that only bolts designed specifically for seat belts be used in this application.2. Stainless steel bolts are not to be used In high load or stressed situations as they do not possess high tensile strength. It is recommended that these bolts be used in locations where the use of ungraded bolts is permitted. 3. The bolt or fastener should be long enough to ensure that at least one clear turn of thread is visible. This applies to all nuts, including nyloc and locking nuts. 4. Locking devices mustbe fitted to all fasteners. These devices include: Spring and shakeproof washers. Nyloc nuts. Deformed thread locknuts or Huck nuts. Castellated nuts with split or roll pins. Lockwire. Split pins. Locking Tabs, and staking.

Trax chassis:There is a fixture on which component of chassis are fixed and welded by CO2 (MAG) welding. After this chassis is brought on another fixture for full welding because there are not some accessible point on main fixture.Main component of chassis frame:Long member (RH/LH) Cross member: there are 6 cross member in TRAX chassis frame.

1st & 6th cross members are front and rear cross members respectively 2nd cross member support the defferential. 3rd cross member support the propeller shaft. 4th cross member is to attatch the dampers at rear.Body mounting brackets: these are provide to bolt the body on the chassis. There are 8 body mounting brackets on each side(RH/LH) Tale lamp: this is for rear lighting & no. plate attatching.Fuel tank brackets: these are to bolt the fuel tank at middle (LH)Upper & lower control arm: these are the part of front independent suspention.Engine mounting brackets: to mount the engine on the chassis.Leaf spring supports for the rear suspention.Damper attatching link at front.Torsional bar : this acts as a spring for front suspension.Towing brackets at front and rear.

Force one chassis:In force one chassis, front suspension system is independent suspension using coil spring & rear suspension is rigid axel suspension using coil spring and trailing arm.Main component of Force one chassis frame:Long members: front(RH/LH)

Middle(RH/LH) Rear(RH/LH)Cross members: there are 7 cross members in Force one chassis frame.

1st & 7th cross members are fitted at front and rear respectively. 2nd & 3rd cross members are given to bolt the lower control arm of front Independent suspension. 4th cross member support the propeller shaft. Remaining cross members make the frame strong.Body mounting brackets: to mounting the body on chassis, there are 6 Brackets on each side.Stearing gear box mounting.Coil spring mounting, to attatch the coil spring in the suspension at Front and rear.Trailing arm brackets, hinge the trailing arm to the frame for rear Suspension.Fuel tank mountings, fuel tank is mounted at LH middle.Foot step brackets, there are 3 brackets at each side(RH/LH)

CONCLUSION

The vocational training enhanced our practical knowledge. Most importantly, we were oriented to the industrial scenario and many challenges and subtleties. The smooth functioning of an industry is depends to a large extent on the mutual co-operation among the different wings. We learnt about the function of different parts of an automobile and the importance of man, machine, method and material in the production system of vehicle. Nevertheless, we did enjoy the training to the fullest and are very sure that this training will help us in our future endeavours.
