Torque converter A torque converter is a type of fluid coupling that is used to transfer rotating power from a prime mover, such as an internal combustion engine, to a rotating driven load. The torque converter normally takes the place of a mechanical clutch in a vehicle with an automatic transmission, allowing the load to be separated from the power source.

Definitions &Translations Torque, moment, or moment of force (see the terminology below) is the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Just as a force is a push or a pull, a torque can be thought of as a twist to an object. Mathematically, torque is defined as the cross product of the lever-arm distance vector and the force vector, which tends to produce rotation. Loosely speaking, torque is a measure of the turning force on an object such as a bolt or a flywheel.

- It is priced to compete with mechanical bending beam, dial, preset and adjustable click-type torque wrenches, and angle gauges. HOW DOES IT WORK? The TECHANGLE wrench emulates a mechanical dial or “click” type wrench or reference-free angle gauge for “turn-of-the-nut” type applications.

Socket wrench A socket wrench is a type of wrench that has a socket attached at one end, usually used to turn a fastener. The most prevalent form is the ratcheting socket wrench, often called a ratchet. A ratchet is a hand tool in which a metal handle is attached to a ratcheting mechanism, which attaches to a socket, which in turn fits onto a type of bolt or nut. Pulled or pushed in one direction, the ratchet loosens or tightens the bolt or nut attached to the socket.

For towing, what's more important, horsepower or torque? Torque and Low-End Power. ­Most drivers know that torqu­e translates into low-end power, or the ability to accelerate the vehicle at low rpm levels. Torque moves the vehicle from a stop and helps it get up steep hills. As such, more torque is required to start a heavier vehicle than a lighter one.

- Torque = Force applied x lever arm. The lever arm is defined as the perpendicular distance from the axis of rotation to the line of action of the force. OK, this is a ridiculously large wrench. But it makes the numbers easy.

Impact Wrench vs. Impact Driver An impact wrench (also known as an impactor, impact gun, air wrench, air gun, rattle gun, torque gun, windy gun) is a socket wrench power tool designed to deliver high torque output with minimal exertion by the user, by storing energy in a rotating mass, then delivering it suddenly to the output shaft.

What does torque mean in terms of car? Torque is the twisting force produced by the engine. In day-to-day driveability terms it is more important than horsepower in determining how quickly the car will accelerate. The torque peak of the engine is where the motor produces the most horsepower for the least RPM, and is therefore, the motor's most efficient speed.

Tension to Torque Conversion Our impact wrench test program is designed to provide a consistent reference standard to compare tool performance over time. Because impact wrenches and pulse tools are usually rated in torque, we also provide data for converting our tension readings into an approximate equivalent reading in foot-pounds. However, conversion of tension to torque involves several complex factors.

wrench noun. verb. The definition of a wrench is a tool with jaws used for holding, turning or twisting. An example of a wrench is what someone would use to loosen and unscrew a bolt. Wrench is defined as to twist or jerk suddenly with force.

Socket wrench A switch is built into the ratchet head that allows the user to apply the ratcheting action in either direction, as needed, to tighten or loosen a fastener. Other common methods of driving socket wrenches include pneumatic impact wrenches, hydraulic torque wrenches, torque multipliers and breaker bars.

Torque wrench If a torque is demanded which is able to defeat the holding force of the roller and spring, the wrench will slip and no torque will be applied to the bolt. A slipper torque wrench will not over tighten the fastener by continuing to apply torque beyond a predetermined limit.

Torque Wrench Myths â Matters Of Precision So if you don’t stretch a bolt enough when tightening the fastener, you won’t get that “pulling” or retracting force on the nut. But if you apply too much force, the bolt will fail. The solution to making sure your most critical fasteners are tightened properly is to use a torque wrench. In its most common form, a torque wrench simply measures the amount of twisting force, or “torque,” that is required to twist a nut or bolt as it’s tightened.

What is torque? Torque is a measure of how much a force acting on an object causes that object to rotate. The object rotates about an axis, which we will call the pivot point, and will label 'O'. We will call the force 'F'. The distance from the pivot point to the point where the force acts is called the moment arm, and is denoted by 'r'.

Wrench A self-tightening wrench with either a chain or strap of metal, leather, or rubber attached to a handle, used to grip and turn smooth cylindrical objects (such as automotive oil filters). It relies entirely on friction between the strap or chain and the object to be manipulated.

- Impact wrenches are one of the most commonly used air tools. In operation, a rotating mass is accelerated by the motor, storing energy, then suddenly connected to the output shaft (the anvil), creating a high-torque impact.

Wrench Types One end may be straight and the other may be offset. Sometimes one end may be a ratchet type. Both ends are normally the same size. Adjustable wrench – An adjustable wrench is a type of wrench with a movable jaw that adapts to different sized nuts or bolts. Adjustable end (Crescent) wrench: This is the most common type of adjustable wrench. The adjustable end wrench is similar to an open end wrench but the spacing is adjustable. It has smooth jaws that mate with two opposite faces of a fastener.
