Definitions

  • the present invention relates to a control pedal for the electrical or electronic control of an actuator mounted on a motor vehicle, for example, the throttle valve of a fuel-injection system in an internal-combustion engine, said control pedal being provided with a mechanical device for the creation of a hysteresis. Said device is designed to simulate the feel of reactivity of a control pedal, coupled mechanically to its actuator.
  • the known art envisages, for instance, that, for the throttle valve of a fuel-injection system in an internal-combustion engine, the actuation is effected via a mechanical connection.
  • the most recent technique has replaced this mechanical connection with a control device controlled either electrically or electronically.
  • Such a resistance is generally obtained, in the known devices, via the friction created between two surfaces in mutual contact, pushed one against the other by the force of one or more springs that work in compression and the thrust of which increases in proportion to the displacement of the pedal to which the device is connected.
  • the purpose of the present invention is to provide a device for the creation of a hysteresis in a pedal control of a motor vehicle that will overcome the aforesaid drawback and at the same time will present a low cost.
  • a pedal for controlling an actuator mounted on a motor vehicle and made of plastic material, said pedal being designed to control the actuator via an electrical or electronic control system (not illustrated), i.e., without there being necessary a mechanical connection, for example, via a Bowden cable.
  • the pedal is pivoted in A with its arm 2, and when pressure is exerted on the top surface 3, it turns in the direction of the arrow B.
  • the top end 4 of the arm 2 projects beyond the axis A and is designed to compress at least one spring 6, set between said end and a fixed part of the motor vehicle (not illustrated); in some cases it is advisable to use a number of springs set alongside one another or set coaxially.
  • the spring 6 on the end 4 rests in a seat 7 obtained by moulding in the top part of a lever 8 made of plastic material, hinged by snap-action with its rounded top end 10 in a seat 11 made in the top edge 12 of the end 4 so that it can rock within the arm 2 of the pedal 1.
  • the bottom part 15 of the lever 8 is shaped like a wedge with triangular cross section and with the thin end of the wedge facing in the direction indicated by the arrow F of the thrust of the spring 6.
  • the two inclined walls 16 and 17 rest exerting thrust against the inclined walls of two inserts 19 and 20, which have a longitudinal section substantially shaped like a right triangle, with the inclined walls set normal to the plane of sliding of the seats 23 and 24 and facing one another.
  • Said inserts are withheld by snap-action coupling 21 and are able to slide and are guided by grooves 22 in two seats 23 and 24 of corresponding shape, made in the side walls of the arm 2 of the pedal 1.
  • the two inserts have dimensions such as to project laterally from the arm 2 and to come to rest against the internal walls, which face them, of a support 25,on which the pedal 1 rotates about the axis A, so that said inserts slide on the internal walls during actuation of the pedal 1.
  • the means for creating the hysteresis may be positioned either above the axis of rotation of the pedal, as in the example illustrated, or else under said axis, according to the design requirements, without departing from the sphere of protection of the invention.
  • materials forming the various parts described previously may be chosen, apart from plastic ones, from amongst any of the ones available to the designer.
