The Steering system provides a Directional control of vehicle to the driver so that he/she is able to turn in the required direction at will instead it goes array. Though the system directs the vehicle in a particular direction, yet it must be arranged geometrically so that all the wheels undergo true rolling motion without slipping. Also, it must be light & stable with a certain degree of self adjusting ability. Steering system Function & Principle: Function: The function of the Steering shoes
for sale system of a vehicle is to convert the rotary motion of the steering wheel into angular turning of the front wheels. It also multiplies the driver's effort at the steering wheel with mechanical advantage to turn the road wheels easily. The front wheels are mounted on the stub axels & they rotate freely. The stub axles in turn are pivoted at the ends of the axle beam which is connected to the driver, the steering system absorbs these shocks. Therefore, steering gears attached to the front are used.
Steering system Principle: The principle of the steering system provides the relative motion between the wheels of a vehical & the road surface to have pure rolling so that wear of tyres is minimum and uniform. The steering gear is so designed that when the vehicle moves on a curved path, the paths of the points of contact of each wheel are concentric circular arcs with the ground. For this purpose, to have proper steering the axis of the rotation of all the wheels meet at a common point called the instantaneous center of rotation of the vehicle. To fulfill this condition, the inner wheel turns through a greater black pumps red soles
angle than the outer wheel. The inner angle ? is greater than outer angle ?, when the vehicle is taking a
right turn. Types of Steering Gears-Worm & Nut, Worm & Wheel Worm, Worm & Roller, Rack & high heals Pinion The steering gear is a christian louboutin low price
mechanism to convert the rotary motion of the steering wheel into to & fro motion of the link rod of the steering linkage to obtain angulat turning of the front wheels. It also provides the necessary leverage so that the driver is able to steer the vehicle without fatigue. The various types of steering gears are: Worm & Nut Steering Gear The constructional features & working of worm & nut type steering gear is shown in fig. In this system the worm is formed at the lower end of the steering shaft & the upper
end is formed st the lower end is fixed to the steering wheel. The steering wheel rotation rotates the worm which in red bottom shoes
turn moves the nut along its length. This causes the drop arm which is splined to the cross shaft to move its end linearly to move the link rod to steer the wheels. Worm & wheel Steering Gear The simplified diagram of wheel type steering gear is shown. It consists of a worm wheel carried in bearings in a cast iron case made in two halves. The worm is keyed to the steering shaft & meshes with the worm wheel. The movement of the steering wheel turns the worm which in turn drives the worm wheel. The drop arm is rigidly attached to the worm wheel spindle. The rotation of the steering wheel is transmitted to the linear motion of the drop arm end which is further connected to the link rod resulting in motion to the stub axle to steer the wheels. Worm & roller Steering Gear It consists of 2 toothed roller is fastened to the cross shaft so that it meshes with the threads of the worm shaft at the end of the steering column. Worm is fastened between the 2 bearings & the play of bearings is adjusted by an adjuster provided at the end of casing. The outer end of the cross shaft is formed in the spindle to fix drop arm. When the steering wheel turns the worm gear, it causes the roller to move in an arc so as to rotate the cross shaft & the drop arm. The drop arm end connected to the link provides a motion to the stub axles to turn the wheels. POWER STEERING There are two types of steering currently in use. These are integral & linkage booster types. Both are operated by hydraulic pressure produced by an engine driven pump to assist in turning the steering mechanism. The integral power system is explained below:- Steering system Steering system Steering systemIntegral Power Steering : The oil pump is belt driven from the engine crankshaft pulley. It consists of a solid cylinder with 2 grooves cut called 'Valve spool' which slides within the hole in the valve housing. The housing has three internal grooves. The central groove is connected to the pump & the other two are connected to the reservoir. The two additional openings are connected to the two sides of the cylinder fitted with piston. The pump delivers the oil in the central part of the housing which flows back to the reservoir by the passage. In this position, there is no oil pressure in the cylinder & there is no tendency for the piston to slide in any direction. Thus there is no steering action & the vehicle moves in straight head position.
