    A variable ratio pedal assembly for operating a push rod that activates a functional system of a vehicle, for example, a push rod of a braking system. The assembly includes an activation piece connected through a pivot tube to an elongated lever structure of the pedal arm, an input piece for connecting to the push rod that is connected to the activation piece, and an intermediate piece connected to the entry part and to a vehicle support. The intermediate piece pivots in relation to the input piece and the support, resulting in a variation in the angle between the input piece and the intermediate piece that creates a relationship that varies as the pedal arm moves.

    Generally speaking, the terms "pedal", "pedal assembly", or "pedal structure" used interchangeably in this specification are not intended to be limited to a specific type of pedal device. They can be used for a brake pedal, in which case the pedal ratio for a brake booster varies. The pedal can be used with any functional system (for example a mechanical or electromechanical system such as a braking system, a transmission) of the vehicle. The method (s) of manufacturing the parts of the pedals disclosed in this document is not intended to be limiting, and may include independent processes and / or secondary processes. For example, the parts of the disclosed pedal assembly can be manufactured or formed through stamping, molding, punching, punching, folding and / or manual processes. In addition, the materials used to manufacture the pedal assembly should not be limiting. The pedal and its parts could be made, for example, of one or more metals, such as steel (tubular or blade type), or plastic materials. The pedal assembly parts could also be manufactured from a combination of
    15 such materials, for example, both metal and plastic.
    Referring now more especially to the drawings, the pedal assembly 10, shown in Figure 1, is a brake pedal 10 connected to a brake booster 28. For explanatory purposes only, the pedal 10 is described with reference to a braking system. , but not 20 should be limited to it. As noted above, the pedal assembly 10 may also be connected, for example, to the parts of a clutch assembly. The pedal assembly 10 is provided in the vehicle in such a way that it is easily accessible for depression by a driver's foot. For example, in some cases, the pedal assembly 10 is mounted in relation to the panels of a control panel 36 and / or an instrument panel (IP). The vehicle dashboard 36, also referred to as a "dashboard," may comprise an upper panel and a lower panel that are connected to each other (for example, using methods or devices known in the art). In some embodiments, the upper control panel and the lower control panel may comprise a uniform or independent part. The panels are generally connected
    30 to a plurality of vehicle devices. For example, dashboard 36 may be connected to another structure 26 of the vehicle, sometimes referred to as a dashboard front (on a lower side or at the bottom) or a firewall. A brake booster 28 of the braking system is fixed to the front of the control panel or firewall 26 and to the brake pedal 10 through a pushrod 14 (described in detail below).

    of a user, the elongated structure 13 is pivoted, which in turn activates the activation part (s) and pushes the push rod 14, and the spring or brake booster mechanism 28 is compressed.
    5 The pushrod 14, which can comprise a larger part and a smaller part, assists in the translation of a force applied on the pedal plate 16 to the brake booster 28. A pedal arm 12 is not directly connected to one end. 17 of the push rod 14 or directly connected to a single piece or to a support that is directly connected to the end 17 of the push rod 14. Rather, arm 12 of
    10 pedal is connected to the push rod 14 through a variable ratio assembly that creates a relationship that varies as the pedal arm moves to activate the push rod 14. The variable ratio assembly includes at least one activation part (for example, part 62, or part 162, and 64), an optional independent thrust part 30 and an intermediate part 60. The end 17 of the push rod 14
    15 is generally mounted to a retainer 50 or to a coupling device of an input part 52 that is connected or to the at least one activation piece, to the intermediate part 60, or to the optional independent thrust part 30.
    According to one embodiment, as seen in Figure 4, the articulation of the assembly of
    Variable pedal ratio can be provided above a lower part of the instrument panel 36. Specifically, the parts of the activation part, the input part and the intermediate part are mounted above a lower part of an instrument panel in the vehicle. The optional thrust piece 30 can also be provided above the bottom of the instrument panel. In one embodiment, the
    25 piece can also be provided above a lower part or the lower part of the board 36. According to one embodiment, a distance D measured in relation to a plane through the pivot point at 22 and the floor F of the vehicle is used to determine an amount of space below the instrument panel 36 (see Figure 4) for a user's foot. In one embodiment, for example, this distance D may be between
    30 approximately 265 mm to approximately 365 mm, inclusive, and may be very along the length of the bottom of the instrument panel 36. In order to provide the articulation of the pedal assembly 10 above the dashboard 36, the locations of the parts and the pivot of the variable ratio pedal assembly can be measured and determined, and for example, a variable ratio curve is calculated in base to these
    35 parameters Such determinations can be used together with distance D to ensure

    As shown by the arrows in Figure 4, when a stepped force is applied to the pedal plate 16, the pedal arm 12 swings forward (to the right) and generally rotates around a horizontal axis toward the front. of the vehicle using the pivot tube 68 and the pin 74. The pivoting movement of the pedal arm 12 pivots the second ends of parts 62 and 64 of the drive piece with the pivot tube 68 (oscillates towards the left), which in turn moves the thrust piece 30. The second end of the thrust piece 30 is subsequently moved to cause the pivoting of the input piece 52 and the intermediate piece 60 around the generally horizontal axes. Specifically, the second end of the thrust piece 30 swings the inlet part 52 forward about the pin 38. At the same time, the intermediate piece 60 is pivoted using the pivot pin 53 and the pivot pin 49 to vary the movement of the input piece 52, and therefore the ratio of the force applied through the push rod 14. The input piece 52 moves substantially in a forward direction. Therefore, push rod 14
    15 is pushed towards the front of the vehicle to operate the braking system. In general, when a force is applied, the spring or brake booster mechanism 28 is compressed. The use of the variable ratio structure (braking) illustrated to push the pushrod 14 through the parts 62, 64, 30, 60 and 52 improves the sensation of pedal operation and allows the pedal ratio to be adjusted to a value wanted.
    20 Figures 5-7 illustrate alternative views of another embodiment of a variable ratio pedal assembly 100 in accordance with an embodiment of this disclosure. For simplicity only, similar parts, as described and noted above with respect to Figures 1-4, have been labeled with the same reference numbers. By
    Therefore, it should also be understood that the characteristics previously indicated with respect to those parts are applied in a similar manner to the embodiment of Figures 5-7 and therefore are not necessarily repeated here and later. In addition, although it is not specifically shown in Figures 5-7, it should be understood that the pedal assembly 100 can be connected to a functional system of a vehicle, for example,
    30 in which the pedal arm 12 is a brake pedal arm for operating an input element (for example, a pushrod 14) connected to a brake booster 28 of a vehicle.
    The pedal arm 12 has an elongated lever structure 13 that is configured to be pivotally mounted, for example, on or near a first end or along

    pivot in relation to the dashboard 36 and the structure 26 of the vehicle, the at least part of the pushrod 14 moves to apply a braking force.
    At least one, if not both pieces 162, 64 also includes a slot for receiving the
    5 cross pin 70 through it. As seen in Figure 6, the transverse pin 70 extends through a groove 71 in the piece 64. The pin 70 is positioned in the same manner as described above through the pieces 162, 64 and in the groove 73 of the elongated lever structure 13. For example, if pin 70 is an I-pin, its ends can be inserted and slid into the grooves to
    10 connect to them. The elongated lever structure 13 is connected to the activation piece (for example, formed by the first and second pieces 162, 64, as shown in Figure 5 and Figure 6) by inserting the transverse pin 70 through of a groove (not shown) in the first piece 162, through the guide grooves 29 of a release lever 124, and through a groove 71 in the second part 64
    15 (and slid into position, as necessary). As seen in Figure 10A, in normal operation, the transverse pin 70 is located in the receiving slot 73 of the elongated lever structure 13, in the lower part of the grooves of the pieces 162, 64, and in one part front of the guide grooves 29 of the release lever 124. As explained in detail below, when a release mechanism is activated, the
    20 transverse pin 70 is guided in and along the grooves and guide grooves 29 and out of the receiving groove 73 of the elongated lever structure 13 so that the pedal arm 12 is disconnected from the lever 124. A then, the elongated lever structure 13 is capable of and is configured to rotate on pin 74.
    25 The pieces 162, 64 can be operatively joined together and connected to the pivot tube 78 at its first ends through the holes 163, 164 in the piece 162 and the hole 67 of the piece 64 in a manner similar to the described above with respect to Figures 1-4, using the hubs 78 and 80 and the pivot shaft 66, with a securing through the clamping element 33. Pivot shaft 66 can be inserted through the
    30 central bore of the connected pivot tube 68 and to the bushings 78, 80 when attached or welded, for example, to parts 162, 64.
    Therefore, when assembled, the first and second pieces 162, 64 are secured in relation to the pivot tube 68 (eg, welded). The pivoting movement of the pedal arm 12 pivotally moves the pivot tube 68 in relation to the
    2. 3
    P201530200
    02-19-2015
    pedal / vehicle mounting bracket 120, thereby pivotally moving parts 162, 64 of the activation piece. The activation piece is thus configured to pivot or rotate with the pivot tube 68 after any pivotal movement of the elongated lever structure 13 of the pedal 12.
    5 Pivoting the pivot tube 68 in turn activates the movement of the other parts of the set of variable ratio parts. The pivoting movement of the pivot tube 68 is configured to drive the movement of the input part 52 (or reinforcement receiving part) that is connected to the push rod 14 that activates the functional system
    10 (mechanical or electro-mechanical) of the vehicle. The input part 52 is operatively connected to the activation part (162, 64) through at least one intermediate part 60. The intermediate part 60 is a secondary part configured to provide, for example, a variable ratio of the braking force, so that the movement ratio applied to the pedal arm 12 moves and varies as the pedal is
    15 pushes or pivots and moves towards board 36.
    In operation, when the pivoting movement of the pedal arm 12 pivotally moves the pivot tube 68 in relation to the vehicle mounting bracket 20 through the activation piece (parts 162, 64), the pivoting movement of the tube 68 pivot
    20 drives at least one pivoting movement of the opposite end of the piece 162. The pivoting movement of the piece 162 drives the movement of the input piece 52 around the pin 138 to allow the pushing of the push rod 14. The movement of the input part 52 is configured to drive the pivoting movement of the intermediate part 60 in relation to both the input part 52 and the pedal support 120 /
    25 vehicle This results in a variation in the angle between the input part 52 and the intermediate part 60. The variation in the angle between the input part 52 and the intermediate part 60 creates a relationship that varies as the pedal arm 12 moves. Consequently, the ratio of the braking force applied from the input part 52 to the push rod 14 is varied.
    30 A portion of the first end of the elongated lever structure 13 may be in the form of a fork and connected to a release lever 124 of a release mechanism (the release mechanism explained in detail below). The release lever 124 can be formed from the supports 126 and 128 that are aligned and connected
    35 to form opposite walls. Brackets 126 and 128 can be connected through
