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] |

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 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheel Hub Assembly
A wheel hub assembly (WHA), also referred to as wikt:hub, hub assembly, wheel hub unit, wheel hub Bearing (mechanical), bearing, etc., is an automotive part used in most cars, passenger vehicles, and light and heavy trucks. Operation The WHA is located between the drum brake, brake drums or disc brake, discs and the drive axle. A wheel is bolted on it. Depending on the construction, the end of hub comes equipped with the Spline (mechanical), splined teeth. They mate the teeth on the axle shaft. The axle hub spins along with the wheels bolted to it and provide the power to the wheels in order to rotate. A Rolling-element_bearing, roller bearing between the axle hub and axle shaft ensures easy rotation of the non-drive wheels. On the axle side, it is mounted to the holding bracket from the chassis; on the disc side, the wheel is mounted to the bolts of the WHA. When replacing, a wheel hub assembly should be torqued to the vehicle's specifications to prevent failure. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Half Shaft
An axle or axletree is a central shaft for a rotating wheel or gear. On wheeled vehicles, the axle may be fixed to the wheels, rotating with them, or fixed to the vehicle, with the wheels rotating around the axle. In the former case, bearings or bushings are provided at the mounting points where the axle is supported. In the latter case, a bearing or bushing sits inside a central hole in the wheel to allow the wheel or gear to rotate around the axle. Sometimes, especially on bicycles, the latter type axle is referred to as a '' spindle''. Terminology On cars and trucks, several senses of the word ''axle'' occur in casual usage, referring to the shaft itself, its housing, or simply any transverse pair of wheels. Strictly speaking, a shaft which rotates with the wheel, being either bolted or splined in fixed relation to it, is called an ''axle'' or ''axle shaft''. However, in looser usage, an entire assembly including the surrounding axle housing (typically a casting) is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transaxle
A transaxle is a single mechanical device which combines the functions of an automobile's transmission, axle, and differential into one integrated assembly. It can be produced in both manual and automatic versions. Engine and drive at the same end Transaxles are nearly universal in all automobile configurations that have the engine placed at the same end of the car as the driven wheels: the front-engine/front-wheel-drive; rear-engine/rear-wheel-drive; and mid-engine/rear-wheel-drive arrangements. Many mid- and rear-engined vehicles use a transverse engine and transaxle, similar to a front-wheel-drive unit. Others use a longitudinal engine and transaxle like Ferrari's 1989 Mondial t which used a "T" arrangement with a longitudinal engine connected to a transverse transaxle. Front-wheel-drive versions of modern Audis, from the A4 upwards, along with their related marques from the Volkswagen Group (which share the same automobile layout) also use a similar layout, b ...

Differential (automotive)
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others, or a fixed multiple of that average. Functional description The following description of a differential applies to a traditional rear-wheel-drive car or truck with an open or limited slip differential combined with a reduction gearset using bevel gears (these are not strictly necessary; see spur-gear differential): Thus, for example, if the car is making a turn to the right, the main ring gear may make 10 full rotations. During that time, the left wheel will make more rotations because it has farther to travel, and the right wheel will make fewer rotations as it has less distance to travel. The sun gears (which drive the axle half-shafts) will rotate at different speeds relative to the ring gear (one faster, one slower) by, say, 2 full turns each (4 full turns relative to each other), resulting in the left wheel mak ...
