TASK-1
Diagnose and repair Light vehicle suspension systems
1. 5 aspects of personal safety during repair of suspension system
· Protection to the eye, by hit by any objects
· Protection to head
· Apron for protection to body
· Face shield for face protection
· Shoes to protect from hit of falling objects or tools
2. Tremendous, disconnect, knuckle, spring, injury
(Filled - in the order of blanks )
3. False (To be supported at the axle, beneath the frame)
4. False (Twisting while carrying heavy loads is not recommended)
5. True(It is recommended to turn at the foot)
6. suspensions , rigid, independent, vehicles, front, rear, Axles, road , transferred, wheel, commercial, move, reduces
(Filled in the order of blanks)
7. Sprung mass is that part of the mass that is directly supported by the spring including the mass of the spring itself. Unsprung mass is the mass that is not directly supported by the spring and this will move up and down along with the spring.
8. Unsprung mass will be mainly responsible for the instability of the vehicle, as it will let the vehicle move up and down as per the profile of the bumps and pits the tyre pass through. Lower and lower unsprung mass will keep the vehicle stable.
9. Ride height is the shortest distance between that part of the vehicle in contact with the road (bottom of the tyre in contact with the road) and the lowest level surface of the vehicle (flat surface below the chassis).
10. Suspension, vehicle, height, spring, control, riding, curb, angles, location, excessive, jounce, control, location , type, level, manufacturer’s measured
(Blanks filled in the order they appear)
11. D. All answers are correct
12. Two types , Linear rate and progressive rate types
13. Progressive rate
14. Jounce
15. In linear rate spring systems, the spring force required for compression or the extension remains constant for throughout the spring operations. However in the variable rate systems there will be variation in the spring force requirements in accordance with the extension or the contraction of the spring.
16. Linear rate springs maintains equal distance between the coils and follows Hooks law. Equal distance compression or the extension will obviously need equal forces.
17. Variable rate springs will operate at lower compression rates at unloaded conditions and will take up more compression during high load compressions. This will be facilitated by variable distances between the coils and subsequent spring forces requirement manipulation.
