Definitions

  • the lever arms of the linkage can each be arranged symmetrically on opposite sides of the adjusting means and the brake booster piston.
  • the coupling gear whose joints and levers, i. arranged on each side of the adjusting means and the brake booster piston the forces on each side of the brake booster piston and the adjusting compensate each other and thus no torque is exerted on these components.
  • the coupling mechanism may comprise a third lever arm, and the second lever arm is pivotally coupled to a third lever arm and the third
  • Fig. 3 shows a desired non-linear relationship between the path of the brake pedal s and the assist force F of a brake booster.
