Scott Russell linkage
A Scott Russell linkage is a type of straight line mechanism which gives a theoretically linear motion by using a linkage form with three portions of the links all equal, and a rolling or sliding connection. It can be used to form a right-angle change of motion, linear-to-linear.
The linkage is named for John Scott Russell (1808–1882), although watchmaker William Freemantle had already patented it in 1803.[1][2]
A different form of the linkage has been used in a front-wheel-drive vehicle with solid rear axle to control lateral movement, and with a flexing elastomeric connection instead of the rolling or sliding connection.[3]
The linkage does not share the disadvantages of the asymmetric Panhard rod, and although more compact than Watt's linkage, it has all the forces concentrated in one link.[4]
