Definitions

  • the present invention relates to an-im- 'DlOVGd suction brake for vehicles equlpped vith internal combustion engines.
  • the braking action is-produced by the'partlal vacuum created-by ftli'e suction of the englne,
  • the part-nil'vacuum act-s on-a plston' working-in a cylinder which can be placedin'"communication with either the atmosphere, or with the suction pipe of the 10 engine.
  • the 'object of the invention is to provide a. brake of the character specified comprismg a minimum nl'iiiiber'of parts-whose opertior'i is certain; the arrangementbeing such as to reduce 'to a minimum the amount of air exhausted by the engine for the braking requirements.
  • the valves for controlling the communication of the bfdke cylinder with the partial-vacuum and with the atmosphere are regulated by a member whose position depends upon the distance" 7 between the two parts of a lost-motionconnection. located between the brake pedalor other brake-controlling element, and the rodding connected with the brakes.
  • This member operates the valves in such manner that the one which controls the communication of the cylinder with the atmos- 0 phere is closed before theone which controls communication with the suction pipe of the engine opens and vice versa.
  • the movements of the valvecontrolling member can be effected by means of a flexible shaft or cable of the Bowden type the wire-and sheath of which are connected 'atone -end to the member in question and to I a fixed part of the apparatus respectively, and at the other end to the two parts of the 40 above-mentioned lost-motion connection.

  • the distributorconsisting For the purpose of co-oi'dinating the movemerits oi the piston in the brake cylinder with the degree of braking force desired b the operator, the distributorconsisting. oi the two valves 8, 9 is controlled from the brake pedal 13 by means of a fork 10 connected to the pedal; by a member 12 here shown as a Bowden shaft.
  • the two prongs of the fork act directly-against stops 8 and 9, rovided on the ends of the tailpieces of t e valves 8, 9 respectively, for opening such valves, and'act oppositely on the valves through springs 11, to close the valves.
  • the brake pedal 13' is connected to a lever arm 6', included -in the brake rodding, and-movable simultaneously and similarly with lever arm 6, by a coupling or lost-motion connection-14 comprising two elements 14 and 14* capable of sliding relatively to each other when pressure is applied to the pedal '13 in a direction indicated by the arrow Y.
  • valve 8 opening the cylinder 3 to the suction of the engine and applying the brakes with additionalpressure, untilwhen the pedal is stopped, thelever arm, throu h its described movement of its part 14" of the lost motion connection will again. close valve 8 to hold the brakes set.
  • each position of the pedal will correspond and determine a braking action of predetermined intensity
  • the braking may be limited at any time by simply stopping the operative move- Y m'cnt of the pedal, and may be increased at any time and to any extent byra continuedand corresponding movement of the pedal.
