IdealDifferential

Ideal differential gear without inertia

Description

The IdealDifferential is an ideal gear without inertia, elasticity, damping or backlash, splitting the torque at the input flange (bottom) intoequal parts for two driven output flanges (left and right). If elasticity, damping or backlash has to be considered, this ideal gearbox has to be connected with corresponding elements.

This component defines the kinematic constraint:

    2 * flange_a.phi = ratio * (flange_left.phi + flange_right.phi) .

Where flange_a is the input flange and flange_left and flange_right are the output flanges.

Parameters

    IdealDifferential_0

  • ratio [-] : Transmission ratio (2*flange_a.phi/(flange_left.phi+flange_right.phi)) (ratio): Scalar.

Ports

  • Port 1 at bottom position: implicit input fixedport numbered 1.
  • Port 1 at left position: implicit output fixedport numbered 1.
  • Port 1 at right position: implicit output fixedport numbered 2.
