8 SUSPENSION I. FRONT INDEPENDENT SUSPENSION 1. CONSTRUCTION DETAILS (Fig. 1) In this independent suspension arrangement each wheel has a separate suspension unit, wheels are connected to the chassis in such a manner that the rise and fall of one wheel has no direct effect on the other. As a result, each wheel has the ability to confirm to maintain a level position regardless of the action of other front wheel. In addition, independent front suspension improves the ride and handling qualities of the vehicle. The upper wishbone is mounted on the frame at its open end through a spindle and pivoted bushes. The closed end of the top wishbone is connected to the top of the stub axle by a ball joint. The lower wishbone is pivoted to chassis frame. Front end of torsion bar is connected to lower wishbone with bracket and rear end of torsion bar is connected to an adjustment lever, mounted at cross member. Ball joint on lower wishbone is connected to bottom end of stub axle. Antiroll bar middle por tion is connected to brackets onRHand LH longmember with bearing blocks (rubber) and clamps. Antiroll bar ends are connected to brackets on lower wishbone with bolts, cups, sleeves and rubber bushes. As the wheel moves up and down, the two control arms (upper wishbone and lower wishbone) pivot up and down, as torsional torque of preloaded torsion bar gives springing actions. The shock absorber located between frame and lower wishbone, dampens the springing oscillations. 2. SPECIFICATIONSANDRECOMMENDATIONS 2A.
