Torque converter - Basic fluid-coupling elements. A torque converter, like any fluid coupling, is a sealed chamber filled with hydraulic fluid (typically light oil) and containing a pump (or impeller) driven by the engine(s) and a turbine connected to an output shaft. The impeller is a toroid disc connected to the engine's crankshaft (or output shaft of the motor or other power source). When the engine or power source is operating it turns the impeller at the same speed. The rotation of the radial c ...

Torque - Moment arm formula. A very useful special case, often given as the definition of torque in fields other than physics, is as follows: The construction of the "moment arm" is shown in the figure below, along with the vectors r and F mentioned above. The problem with this definition is that it does not give the direction of the torque but only the magnitude, and hence it is difficult to use in three-dimensional cases. If the force is perpendicular to the displacemen ...

In physics, torque can be thought of informally as "rotational force". Torque is measured in units of newton metres, and its symbol is τ. The concept of Torque, also called moment or couple, originated with the work of Archimedes on levers. The rotational analogues of force, mass and acceleration are torque, moment of inertia and angular acceleration respectively. The force applied to a lever, multiplied by its distance from the lever's fulcrum, is the torque. For example, a force of three newtons applied two metres fro ...

Torque is part of the basic specification of an engine: the power output of an engine is expressed as its torque multiplied by its rotational speed. Internal-combustion engines produce useful torque only over a limited range of rotational speeds (typically from around 1,000–6,000 rpm for a small car). The varying torque output over that range can be measured with a dynamometer, and shown as a torque curve. The peak of that torque curve usually occurs somewhat below the overall power peak. The torque peak cannot, by definition, ...

If a force is allowed to act through a distance, it is doing mechanical work. Similarly, if torque is allowed to act through a rotational distance, it is doing work. Power is the work per unit time. However, time and rotational distance are related by the angular speed where each revolution results in the circumference of the circle being travelled by the force that is generating the torque. This means that torque that is causing the angular speed to increase is doing work an ...

The bell housing is part of the transmission system on a petrol or diesel powered vehicle. It is bolted to the engine block and contains the flywheel, the torque converter or clutch of the transmission. The starter motor is usually mounted here engaging with a ring gear on the flywheel. On the opposite end to the engine is usually bolted the gearbox. The above is the normal arrangement for an in line transmission system for a conventional rear wheel drive or all wheel drive vehicle. The arrangement for a transverse mounted engine and ...

Dilatant materials have certain industrial uses due to their shear thickening behavior. For example, some all wheel drive systems use a torque converter full of dilatant fluid to provide power transfer between front and rear wheels. On high traction pavement, the relative motion between primary and secondary drive wheels is the same, so the shear is low and little power is transferred. When the primary drive wheels start to slip, the shear increases, causing the fluid to thicken. As the fluid thickens, the torque transferred to the secondary ...

The Ultramatic was a hydraulic torque converter automatic transmission with a two-speed plus reverse epicyclic geartrain and torque converter lockup, called Direct Drive by Packard. The unit was hydraulically controlled with a valve body, like most automatic transmissions before the advent of electronic control. The original Ultramatic did not switch automatically between high and low gearing ratios; the driver selected high or low ratio through the column shift lever. The intention was that in normal driving, the high (1:1) ra ...

John De Lorean - Packard Motor Company. DeLorean's time in the employ of Chrysler lasted less than a year, when he was offered a $14,000 per year position at Packard Motor Company under supervision of noted engineer Forest McFarland. DeLorean quickly drew attention at his new employer with his development of an improvement to the company's Ultramatic automatic transmission, giving it a much improved torque converter and dual drive ranges; it was launched as the "Twin-Ultramatic". However, Packard was in serious f ...

In 1955, Packard switched to a new V8 engine from its traditional straight-8, and launched a new evolution of its automatic transmission at the same time, the Twin-Ultramatic Drive. McFarland, his assistant John DeLorean, and their team were not satisfied with the improved pick-up of the Gear-Start Ultramatic, and modified the angle of the converter “pump” to allow a higher stall speed thus increasing the torque multiplication better suited to the torque curve of the new V8 engines. In addition a slightly higher stall converter wa ...

Manual transmissions are typically compared to automatic transmissions, as the two represent the majority of options available to the typical consumer. These comparisons are general guidelines and may not apply in certain circumstances. Additionally, the recent popularity of semi-manual and semi-automatic transmissions renders many of these points obsolete. It should be kept in mind that many some of these points are true of "conventional" automatic transmissions which shift gears and are coupled to the engine with a torque converter but are not a true comparison or do not apply to other ...

Most often, bulldozers are large and powerful tracked engineering vehicles. The tracks give them excellent ground hold and mobility through very rough terrain. Wide tracks help distribute the bulldozer's weight over large area (decreasing pressure), thus preventing it from sinking in sandy or muddy ground. Extra wide tracks are known as 'swamp tracks'. Bulldozers have excellent ground hold and a torque divider designed to convert the engine's power into dragging ability , letting the bulldozer use its own weight to push very he ...

In 1989 the 6 Series was supplanted by the 8 Series, but in late 2003, the 6 Series was reintroduced as a 2004 model, with coupe and convertible versions based on the BMW E63 and BMW E64 platforms, respectively. These two models are each available with either a 3.0 L (2996 cc) straight-6 making 190 kW (258 hp DIN) at 6600 RPM and 300 Nm (221.3 ft.lbf) of torque from 2500–4000 RPM (in the 630i) or a 4.4 L (4398 cc) V8 making 245 kW (333 hp DIN) and 450 Nm (331.9 ft ...

The most important class of three-phase load is the electric motor. A three phase induction motor has a simple design, inherently high starting torque, and high efficiency. Such motors are applied in industry for pumps, fans, blowers, compressors, conveyor drives, and many other kinds of motor-driven equipment. A three-phase motor will be more compact and less costly than a single-phase motor of the same voltage class and rating; and single-phase AC motors above 10 HP (7.5 kW) are uncommon. Large air conditioning equipment (for example, most York units above 2.5 tons (8.8 kW) cooling capacit ...

Modelling A locomotive (from lat. locus motivus) is a railway vehicle that provides the motive power for a train, and has no payload capacity of its own; its sole purpose is to move the train along the tracks. In contrast, many trains feature self-propelled payload-carrying vehicles; these are not normally considered locomotives, and may be referred to as multiple units or railcars; the use of these self-propelled vehicles is increasingly common for passenger trains, but very rare for freight (see however CargoSprinter). ...
