Components of Suspension System and Problems of the Suspension System

-

Components of Suspension System

1.     Control Arm: A movable lever that fastens the steering knuckle to the frame of the vehicle.

2.     Control Arm Bushing: This is a sleeve that allows the control arm to move up and down on the frame.

3.     Strut Rod: Prevents the control arm from swinging forward and backward.

4.     Ball Joints: A joint that allows the control arm and steering knuckle to move up and down and sideways as well

5.     Shock absorbers or Struts: prevents the suspension from bounce after spring compression and extension

6.     Stabilizer Bar: Limits body roll of the vehicle during cornering

7.     Spring: Supports the weight of the vehicle


Common Problems of the Suspension System

Shocks and Struts: 

    


Ball joints: 

    

Preventive Measures for Suspension System

  • The shocks and struts should be check frequently for leakages
  • Ball joints should be checked immediately in case the motion of the car is not right.
  • Make sure to lubricate the ball joints of your car frequently.

Types of Flexible Coupling – Bibby Resilient Couplings

Types of Flexible Coupling – Bibby Resilient Couplings                  Named after its Inventor Dr. James Bibby in 1917, this coupling is still one of the most sought after flexible couplings for heavy shock applications. Let us now look at the constructional features of the coupling. 1.       The Coupling consists of two flanges or hubs specifically mounted on the drive and the driven shafts respectively. These hubs contain axial grooves cut on their circumference. 2.       The two couplings are joined or held together by means of a specially designed grid spring. 3.       The total assembly is enclosed in a casing or shell filled with grease for low-speed applications or, in high-speed applications with high viscosity oil. Now let’s look at the working aspect of the coupling and how it tends to reduce vibration and prevents the build-up of resonance in the system. a.) The specially designed spring is wound up through the grooves forming a series of resilient bridges throughout the p

Safety Systems in Vehicles | Seat Belts | Air Bags Seat belts                The function of the seat belts is to restrain the occupants of a vehicle in their seats when the vehicle hits an obstacle:                Three-point seat belt: In motoring history, this is the single most significant advance. All credit goes to Volvo’s Nils Bolin for devising it and to Volvo for introducing it in 1959. The three-pointer afforded unrivaled restraint. Its use was a quick, easy one-handed operation. Many improvements have been made to the webbing, mountings, latches, and inertia reels and belts have got smarter in relating to accident severity and occupant weight. In the present day vehicles, seat belts have become mandatory for the driver and front passenger. Some vehicles have seat belts for rear passengers also.                Seat belt pre-tensioner: A spring-loaded or explosive device that reacts to a severe frontal impact by automatically snugging the seat belt tight for fully effective re

What Is Nvh ???

What Is Nvh ? Noise:                Noise is defined as an unpleasant or unexpected sound created by a vibrating object. Vibration:                Vibration is defined as any objectionable repetitive motion of an object, back-and-forth or up-and-down. Harshness:                Harshness is defined as an aggressive suspension feel or lack of “give” in response to a single input. Noise and Vibration Theory:                A vibrating object normally produces sound, and that sound may be an annoying noise. In the case where a vibrating body is the direct source of noise (such as combustion causing the engine to vibrate), the vibrating body or source is easy to find. In other cases, the vibrating body may generate a small vibration only. This small vibration may cause a larger vibration or noise due to the vibrating body’s contact with other parts. When this happens, attention focuses on where the large vibration or noise occurs while the real source often escapes notice.                 A
