Spindle (automobile)
In an automobile, the wheel spindle, sometimes simply called the spindle, is a part of the suspension system that carries the hub for the wheel and attaches to the upper and lower control arms. Spindles are carried by steering knuckles or "uprights". Although, the terms "steering knuckle" and "upright are sometimes used interchangeably with "spindle", they refer to different parts. Design There are several considerations when designing a spindle. Loads and forces need to be considered. Vertical and horizontal forces greater than those due to 5 times the acceleration of gravity, that is, approximately 50 meters per second squared, are sometimes considered desirable. Non-driven wheel The main forces on a non-driven wheel are braking and turning forces. Driven wheel The forces on a driven wheel include forward and reverse propulsion as well as the braking and turning forces.

Automobile
A car or automobile is a motor vehicle with Wheel, wheels. Most definitions of ''cars'' say that they run primarily on roads, Car seat, seat one to eight people, have four wheels, and mainly transport private transport#Personal transport, people instead of cargo, goods. The year 1886 is regarded as the birth year of the car, when German inventor Carl Benz patented his Benz Patent-Motorwagen. Cars became widely available during the 20th century. One of the first cars affordable by the masses was the 1908 Ford Model T, Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the US, where they replaced Draft animal, animal-drawn carriages and carts. In Europe and other parts of the world, demand for automobiles did not increase until after World War II. The car is considered an essential part of the Developed country, developed economy. Cars have controls for driving, parking, passenger comfort, and a variety of lights. Over the decades, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suspension (vehicle)
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both road holding/ handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the road or ground forces acting on the vehicle do so through the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front and rear suspension of a car may be different. History An early form of suspension on ox-drawn carts had the platform swing on iron chains attached to the wheeled frame of the carriage. This system remained the basis for most suspension systems until the turn of the 19th century, although the iron cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Control Arm
In automotive suspension, a control arm, also known as an A-arm, is a hinged suspension link between the chassis and the suspension upright or hub that carries the wheel. In simple terms, it governs a wheel's vertical travel, allowing it to move up or down when driving over bumps, into potholes, or otherwise reacting to the irregularities of a road surface. Most control arms form the lower link of a suspension. The inboard (chassis) end of a control arm is attached by a single pivot, usually a rubber bushing. It can thus control the position of the outboard end in only a single degree of freedom, maintaining the radial distance from the inboard mount. Although not deliberately free to move, the single bushing does not control the arm from moving back and forth; this motion is constrained by a separate link or radius rod. This is in contrast to the wishbone, which are triangular and have two widely spaced inboard bearings. These constrain the outboard end of the wishbone from ...

Steering Knuckle
300px, Double Wishbone Suspension In automotive suspension, a steering knuckle or upright is that part which contains the wheel hub or spindle, and attaches to the suspension and steering components. The terms ''spindle'' and ''hub'' are sometimes used interchangeably with steering knuckle, but refer to different parts. The wheel and tire assembly attach to the hub or spindle of the knuckle where the tire/wheel rotates while being held in a stable plane of motion by the knuckle/suspension assembly. In the attached photograph of a double-wishbone suspension, the knuckle is shown attached to the upper control arm at the top and the lower control arm at the bottom. The wheel assembly is shown attached to the knuckle at its center point. Note the arm of the knuckle that sticks out, to which the steering mechanism attaches to turn the knuckle and wheel assembly. Types Steering knuckles come in all shapes and sizes. Their designs differ to fit all sorts of applications and suspen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Front Axle Assembly
Turning radius was a longstanding problem with wagons, dictated by the distance between the front wagon wheels and the bed of the wagon—namely, the point where the rotating wheels collide with the side of the wagon when turning. Many earlier designs required a very large turning radius; however, shrinking the width of the bed means decreasing the size of the load. As this is a problem that carts (by virtue of their two-wheeled nature) do not face, this factor, combined with their lighter weight, meant that carts were long preferred over wagons for many uses. The general solutions to this problem involved several modifications to the front-axle assembly. The front axle assembly of a wagon consists of an axle, a pair of wheels and a round plate with a pin in its centre that sits halfway between the wheels, which may be mounted on spindles. A round plate with a hole in its centre is located on the underside of the wagon. The plate on the wagon, in turn, sits on the plate on the axle ...

Pintle
A pintle is a pin or bolt, usually inserted into a gudgeon, which is used as part of a pivot or hinge. Other applications include pintle and lunette ring for towing, and pintle pins securing casters in furniture. Use Pintle/gudgeon sets have many applications, for example: in sailing to hold the rudder onto the boat; in transportation a pincer-type device clamps through a lunette ring on the tongue of a trailer; in controllable solid rocket motors a plug moves into and out of the motor throat to control thrust. In electrical cubicle manufacture, a pintle hinge is a hinge with fixed and moving parts. The hinge has a pin "pintle" and can be both external and internal. The most common type consists of three parts. One part on the body of the cubicle, one part on the door and the third part is the pintle. In transportation, a ''pintle hitch'' is a type of tow hitch that uses a tow ring configuration to secure to a hook or a ball combination for the purpose of towing an unpowered v ...
