2. Drag link - Wikipedia

   en.wikipedia.org/wiki/Drag_link

   An alternate steering mechanism is a rack and pinion, a three bar linkage that eliminates the drag link by directly moving a center link. "The drag link connects the pitman arm to the steering arm, or in some applications it connects to the tie rod assembly. Unlike a center link, the drag link does not connect to an idler arm, and has no inner ...

3. Pitman arm - Wikipedia

   en.wikipedia.org/wiki/Pitman_arm

   In automotive or truck steering systems, the Pitman arm acts as a linkage attached to the steering box (see recirculating ball) sector shaft, [1] it converts the angular motion of the sector shaft into the linear motion needed to steer the wheels. The arm is supported by the sector shaft and supports the drag link or center link with a ball ...

4. Steering linkage - Wikipedia

   en.wikipedia.org/wiki/Steering_linkage

   The steering linkage which connects the steering gearbox to the front wheels consists of a number of rods. These rods are connected with a socket arrangement similar to a ball joint, called a tie rod end, allowing the linkage to move back and forth freely so that the steering effort will not interfere with the vehicles up-and-down motion as the ...

5. Ackermann steering geometry - Wikipedia

   en.wikipedia.org/wiki/Ackermann_steering_geometry

   The steering pivot points [clarification needed] are joined by a rigid bar called the tie rod, which can also be part of the steering mechanism, in the form of a rack and pinion for instance. With perfect Ackermann, at any angle of steering, the centre point of all of the circles traced by all wheels will lie at a common point.

6. Kinematic diagram - Wikipedia

   en.wikipedia.org/wiki/Kinematic_diagram

   In mechanical engineering, a kinematic diagram or kinematic scheme (also called a joint map or skeleton diagram) illustrates the connectivity of links and joints of a mechanism or machine rather than the dimensions or shape of the parts. Often links are presented as geometric objects, such as lines, triangles or squares, that support schematic ...

7. Parallelogram steering linkage - Wikipedia

   en.wikipedia.org/wiki/Parallelogram_steering_linkage

   A parallelogram steering linkage is called such because like its namesake, the two sides of the linkage run parallel to each other and are equal in distance. This type of steering linkage uses four tie rods, one inner and one outer on each side (left and right) that are connected by an adjustment sleeve, a center link (which runs between the tie rods), an idler arm on the passenger side, and a ...

8. Watt's linkage - Wikipedia

   en.wikipedia.org/wiki/Watt's_linkage

   Thus, link 1 (total distance between ground joints): + Hand-drawn diagram by James Watt (1808) in a letter to his son, describing how he arrived at the design. [ 1 ] A Watt's linkage is a type of mechanical linkage invented by James Watt in which the central moving point of the linkage is constrained to travel a nearly straight path .

9. Three-point hitch - Wikipedia

   en.wikipedia.org/wiki/Three-point_hitch

   Three-point hitches are composed of three movable arms. The two lower arms—the hitch lifting arms—are controlled by the hydraulic system, and provide lifting, lowering, and even tilting to the arms. The upper center arm—called the top link—is movable, but is usually not powered by the tractor's hydraulic system.
