What is meant by Full elliptic leaf springs?
The advantage of this type is the elimination of shackle and spring. The lubrication and wear frequently which are on of the main draw back of this type of springs.
Types of Leaf Springs?
1. Full – elliptic type
2. Semi – elliptic type
3. Three Quarter – elliptic type
4. Transverse Spring type
5. Helper Spring type
Types of suspension springs?
1. Steel Springs :
a. Leaf Springs
b. Coil Springs
c. Torsion bar Springs
2. Rubber Springs:
a. Compression Springs
b. Progressive Springs
3. Plastic Springs
4. Air Springs:
a. Bellow Type
b. Pestoon Type
5. Hydraulic Type
What are the basic suspension movements?
The vertical movement of the complete body.
2. Pitching:
The rotating movement of all the parts between the spring and road and the portion of spring weight itself.
3. Rolling:
The movement about longitudinal axis produced by the centrifugal force during cornering.
What is meant by Sprung Weight and un Sprung Weight?
Sprung Weight:
It is weight of all the parts supported by the spring including weight of the spring.
Un sprung weight:
It is the weight of all the parts between the spring and rod and the portion of spring weight it self.
Advantages of Suspension system?
1. It provides softer suspension.
2. It reduces wheel wobbling.
3. It reduces the tendency of fitting of the wheel on one side due to road vibration.
4. It provides more space for engine accommodation.
5. It promotes under steer which results low un sprung weight.
6. The movement of the spring on one wheel is not transmitted to the other wheel.
