Linkages
Design & Technology: AQA GCSE, topic 1.5.3
Linkages
A linkage is a group of rigid links or levers connected together to create a range of movement. Linkages are used to change the type, direction and/or force of a motion.
Bell crank linkages
- A bell crank linkage changes the direction of motion through 90°.
- It can be used to change a side to side (horizontal) motion to an up and down (vertical) motion.
Bell crank linkage
Push/pull linkages
- The push/pull linkage keeps the direction of motion the same for the input and the output.
Push/pull linkage
Reverse motion linkages
- The reverse motion linkage reverses the motion of the input and giving an opposite output motion.
