6. STEERING DESIGN
The steering used here is based on the RACK AND PINION principle, for effective steering and to avoid high steering ratio and the need for tires to slip sideways while following the path around a curve.
Wheel Base (l) = 1143 mm
Track Width Front (w) = 1054 mm
Steer angle of the inner wheel= 22.5°
Steer angle of the outer wheel =16.57°
Steering ratio = 6:1
Tangential force to be made in the steering wheel
by the driver to turn the wheel, T = N

7. BRAKING SYSTEM Type of brake: DISC BRAKE
DIMENSIONS OF THE BRAKE SYSTEM
Caliper diameter= 200 mm
Caliper piston diameter= 40 mm
Master cylinder diameter D= 19.05mm
Rolling Radius of Tire= m
Max force applied at the pedal= 20 kgf
Pedal ratio= 4:1

BRAKE FORCE ANALYSIS:
Force required to make tires skid = Rrear * (Rtyre / Rrotor)
= *(0.1296/0.1)
= N
Radius of brake pad rp= 20mm
Area of the brake pad =2 * π rp2
=2.51 * 10-3 m
Pressure applied =force/area
= kPa
Maximum allowable pressure on steel rotor = 2680 kPa
Factor of safety = 2680/ =
Therefore, the System is Safe.
STOPPING DISTANCE =3.528 M
STOPPING TIME=0.94sec

9. TRANSMISSION Properties of the frame
CHARGER SPECIFICATIONS:
CHAIN AND SPROCKET Transmission:.
Helps in better racing experience for the driver.
Vehicle Design Criteria:
▪ Gross vehicle weight (GVW): N
▪ Weight on each
Drive wheel (WW): N
▪ Rolling Radius
of wheel/tire (Rw): m
▪ Maximum incline angle (α) : 2 degree
▪ Worst working surface concrete (good)
Calculations with gear ratios
* Max. Speed of motor at 48V = 4500 rpm
* Desired top speed = 75kmph
Desired power shaft rpm = rpm
Considering the starting torque and top speed, the following sprocket ratio is selected.
 Driven sprockets of teeth =32.
Drive sprocket of teeth =11.
Gear ratio =2.9
Speed of the driven sprocket = rpm
Speed of the driver sprocket = rpm

10. TYRES AND WHEELS
Tyres form one of the most integral parts of the go-kart as they are in
contact with the road surface all the time.
Hence a go-kart tire that provides enough traction, so as to transmit the torque available at the wheels without
causing slipping need to be selected.
Hence MRF ZW3 GOKART tires
with following specifications are selected and as follows.

11. FRONT TIRES REAR TIRES Specification -150/270-2 tires
Width – 80 mm
Outer diameter of tire – 257 mm
Outer diameter of rim – 5 inch
