A Seminar On POWER STEERING GUIDED BY PROF.S.M.MAGDUM PRESENTED BY MR.RAHUL S.MAHADIK

PowerPoint Presentation: 

With increasing demand for light control Aligning tyre torque for keeping vehicle load acceptable. Power steering has Become necessary in most of the vehicle. In order to reduce the steering wheel turning Effort, turn sharp corner easily, negotiate Winding roads and monocurve the vehicle. In confirmed space as well as to offer some Resistance to make the drive steering res- Ponce power steering has been used. Introduction

Steering System: 

Steering System Function of Steering System Control of front wheel (sometimes rear wheel) direction. Maintain correct amount of effort needed to turn the wheels. Transmit road feel (slight steering wheel pull caused by the road surface) to the drivers hand. Absorb most of the shock going to the steering wheel as the tire hits holes and bumps in the road. Allow for suspension action.

Steering System: 

Steering System Power Steering normally use an engine driven pump and a hydraulic system to assist steering action. Three major types of power steering systems: Integral-piston linkage system. External power steering system. Rack-and-pinion system Integral power piston. External power piston. Integral Rack-and-pinion system is the most common.

Steering System: 

Steering System Turning the Car (when turning, front wheels don’t point the same direction) Inside wheel turns at a smaller radius, hence the inside wheel turns at a steeper angle then the outside wheel.

Steering System: 

Steering System Linkage Steering System (Worm Gear) Parts Steering Wheel – used by the driver to rotate a steering shaft that passes through the steering column. Steering Shaft – transfers turning motion from the steering wheel to the steering gearbox. Steering Column – supports the steering column and steering shaft.

Steering System: 

Steering System Linkage Steering System (Worm Gear) Parts Steering Gearbox) – changes turning motion into a straight-line motion to the left or right. Steering gear box ratios range from 15:1 to 24:1 (with 15:1, the worm gear turns 15 times to turn the selector shaft once). Steering linkage – connects the steering gearbox to the steering knuckles and wheels.

Steering System: 

Steering System Basic Rack-and-Pinion Steering Part of rack contains a piston Two fluid ports, one on each side. The side with high pressure pushes the piston to the opposite side (turning the wheel).

Steering System: 

Steering System Basic Rack-and-Pinion Steering Pinion Gear- rotated by the steering wheel and steering shaft; it’s teeth mesh with the teeth on the rack. Rack- long steel bar with teeth along one section; slides sideways as the pinion gear turns.

PowerPoint Presentation: 

Idler Arm supports the end of the center link on the passenger side of the vehicle. Steering Linkage Bolts to the vehicle’s frame. If worn, will cause excessive steering play. Tie-Rod Assemblies : Two tie-rod assemblies are used to fasten the center link to steering knuckles. Assembly is consist of inner tie-rod end, outer tie-rod end, and a toe adjustment sleeve.

Steering Linkage: 

Steering Linkage Pitman Arm transfers gearbox motion to the steering linkage. Pitman arm is splined to the gearbox. Center Link (Relay Rod) steel bar connects the right and left side of the steering linkage. Connects to Pitman arm, Tie rod ends, and Idler arm.
