The primary purpose of the steering system is to allow the driver to guide the vehicle. Bell crank steering linkage. Rack and pinion steering linkage. IntroductioneditThe most conventional steering arrangement is to turn the front wheels using a handoperated steering wheel which is positioned in front of the driver, via the steering column, which may contain universal joints which may also be part of the collapsible steering column design, to allow it to deviate somewhat from a straight line. Other arrangements are sometimes found on different types of vehicles, for example, a tiller or rearwheel steering. Tracked vehicles such as bulldozers and tanks usually employ differential steering that is, the tracks are made to move at different speeds or even in opposite directions, using clutches and brakes, to bring about a change of course or direction. Wheeled vehicle steeringeditBasic geometryedit. Ackermann steering geometry. Ackerman steering linkage. Caster angle indicates kingpin pivot line and gray area indicates vehicles tire with the wheel moving from right to left. A positive caster angle aids in directional stability, as the wheel tends to trail, but a large angle makes steering more difficult. Curves described by the rear wheels of a conventional automobile. While the vehicle moves with a constant speed its inner and outer rear wheels do not. The basic aim of steering is to ensure that the wheels are pointing in the desired directions. This is typically achieved by a series of linkages, rods, pivots and gears. One of the fundamental concepts is that of caster angle each wheel is steered with a pivot point ahead of the wheel this makes the steering tend to be self centering towards the direction of travel. The steering linkages connecting the steering box and the wheels usually conform to a variation of Ackermann steering geometry, to account for the fact that in a turn, the inner wheel is actually travelling a path of smaller radius than the outer wheel, so that the degree of toe suitable for driving in a straight path is not suitable for turns. The angle the wheels make with the vertical plane also influences steering dynamics see camber angle as do the tires.

Rack and pinion unit mounted in the cockpit of an Ariel Atom sports car chassis, atypical of contemporary production automobiles. Non assisted steering box of a motor vehicle. Many modern cars use rack and pinion steering mechanisms, where the steering wheel turns the pinion gear the pinion moves the rack, which is a linear gear that meshes with the pinion, converting circular motion into linear motion along the transverse axis of the car side to side motion. This motion applies steering torque to the swivel pin ball joints that replaced previously used kingpins of the stub axle of the steered wheels via tie rods and a short lever arm called the steering arm. The rack and pinion design has the advantages of a large degree of feedback and direct steering feel. A disadvantage is that it is not adjustable, so that when it does wear and develop lash, the only cure is replacement. BMW began to use rack and pinion steering systems in the 1. European manufacturers adopted the technology. American automakers adopted rack and pinion steering beginning with the 1. Ford Pinto. 1Older designs use two main principles the worm and sector design and the screw and nut. Both types were enhanced by reducing the friction for screw and nut it is the recirculating ball mechanism, which is still found on trucks and utility vehicles. The steering column turns a large screw which meshes with nut by recirculating balls. The nut moves a sector of a gear, causing it to rotate about its axis as the screw is turned an arm attached to the axis of the sector moves the Pitman arm, which is connected to the steering linkage and thus steers the wheels. The recirculating ball version of this apparatus reduces the considerable friction by placing large ball bearings between the screw and the nut at either end of the apparatus the balls exit from between the two pieces into a channel internal to the box which connects them with the other end of the apparatus, thus they are recirculated. The recirculating ball mechanism has the advantage of a much greater mechanical advantage, so that it was found on larger, heavier vehicles while the rack and pinion was originally limited to smaller and lighter ones due to the almost universal adoption of power steering, however, this is no longer an important advantage, leading to the increasing use of rack and pinion on newer cars. The recirculating ball design also has a perceptible lash, or dead spot on center, where a minute turn of the steering wheel in either direction does not move the steering apparatus this is easily adjustable via a screw on the end of the steering box to account for wear, but it cannot be entirely eliminated because it will create excessive internal forces at other positions and the mechanism will wear very rapidly. This design is still in use in trucks and other large vehicles, where rapidity of steering and direct feel are less important than robustness, maintainability, and mechanical advantage. The worm and sector was an older design, used for example in Willys and Chrysler vehicles, and the Ford Falcon 1. To reduce friction the sector is replaced by a roller or rotating pins on the rocker shaft arm. Other systems for steering exist, but are uncommon on road vehicles. Childrens toys and go karts often use a very direct linkage in the form of a bellcrank also commonly known as a Pitman arm attached directly between the steering column and the steering arms, and the use of cable operated steering linkages e. Power steeringeditPower steering helps the driver of a vehicle to steer by directing some of its power to assist in swiveling the steered road wheels about their steering axes. As vehicles have become heavier and switched to front wheel drive, particularly using negative offset geometry, along with increases in tire width and diameter, the effort needed to turn the wheels about their steering axis has increased, often to the point where major physical exertion would be needed were it not for power assistance. To alleviate this auto makers have developed power steering systems, or more correctly power assisted steering, since on road going vehicles there has to be a mechanical linkage as a fail safe. There are two types of power steering systems hydraulic and electricelectronic. A hydraulic electric hybrid system is also possible. A hydraulic power steering HPS uses hydraulic pressure supplied by an engine driven pump to assist the motion of turning the steering wheel. Electric power steering EPS is more efficient than hydraulic power steering, since the electric power steering motor only needs to provide assistance when the steering wheel is turned, whereas the hydraulic pump must run constantly. In EPS, the amount of assistance is easily tunable to the vehicle type, road speed, and even driver preference. An added benefit is the elimination of environmental hazard posed by leakage and disposal of hydraulic power steering fluid. In addition, electrical assistance is not lost when the engine fails or stalls, whereas hydraulic assistance stops working if the engine stops, making the steering doubly heavy as the driver must now turn not only the very heavy steeringwithout any helpbut also the power assistance system itself.

An ebay buy it now price seen online November 5 2. REX VILLIERS 9. 8CC SKULLCRUSHER. I have decided to sell one of my rarest and most unique motorcycle, my 1. REX Villiers 9. 8cc. It was manufactured by REX, a Swedish bicycle and motorcycle manufacturer, in 1. It was sold new and registered by Mr Alf Ivar Gustavsson in my hometown of Linkoping Sweden. A copy of the first registration is among the pictures. The 2 stroke and 2 speed motorcycle engine was manufactured by Villiers Enginering, a manufacturer of bicycle and motorcycle parts based in Villiers Street, Wolverhampton, England. Due to the small size of the engine it was named the Midget Engine. REX started to build bicycles in 1. Harley Davidson and Husqvarna and 1. Royal Enfield build their first motorcycles. The problems with the motorcycles produced in the early 1. In the early 1. 93. Sweden was plagued by the Great Depression and the Swedish financial crises Kreugerkrashen. The main mean of transportation was the bicycle and basically all people had access to their own bicycle. There were at least 2. Sweden and they competed fearlessly for the domestic market share. The bicycle manufacturers developed a new strategy to provide the Swedes a new mean of transportation, the lightweight motorcycle lattviktare. The goal for the new motorcycle was to sell it at a price that as many could afford as possible. The motorcycles were sold for about 4. About 1. 0 of the 2. The only regulatory requirement to ride the lightweight motorcycle was the minimum 1. The young men of Sweden took this new lightweight motorcycle to their heart because enabled them to travel much farther out and meet new girls in new towns, but still make it home in the evening so they could ride it to work in the morning. It is even said that these lightweight motorcycles abolished the inbreeding in the small town of Sweden. During the years of 1. Sweden. REX with the Villiers engine was one of the most attractive and popular Swedish built motorcycles. However, the combination of poor no regulations, the poorly maintained gravel roads, the inexperienced riders and sometimes a little too much of the good dating life resulted in a significant amount of accidents. It was so bad that the lightweight motorcycles were named Skallkrossare Skullcrushers. On July 1, 1. 93. The new regulation, effective on July 1, 1. Hitlers invasion of Poland on September 1, 1. World War II, killed the Skullcrushers and made them gradually disappear for newer and more today looking motorcycles. My 1. 93. 7 REX Villiers is in very good condition, has an older restoration and has been driven over the last years. It would benefit from a carb cleaning to start better. You can add it to your collection or just drive it around. It has a two stroke and two speed engine with gear stick and clutch.
