Definitions

  • the invention relates to a Device for actuating at least one throttle valve with one Actuator, such as a twist grip, at least one with it kinematically coupled, pivotable via an actuation angle Throttle valve and one in the transmission path between Actuator and throttle valve (s) arranged Translation device for generating a progressive Transmission behavior according to a progressive Total transfer function.
  • Actuator such as a twist grip
  • Throttle valve one in the transmission path between Actuator and throttle valve (s) arranged Translation device for generating a progressive Transmission behavior according to a progressive Total transfer function.
  • Such throttle valve actuations are used in particular motorcycles used.
  • a not too large actuation path on Throttle twistgrip required, so that in the middle and upper load range low twist of the throttle grip a relatively large one Throttle valve adjustment conditional, on the other hand, especially in lower load range, the demand for good meterability, so that In this load range, a large rotation of the Throttle twist grip causes a relatively small throttle valve adjustment.
  • the path on the Actuator such as the twist grip
  • the path on the Actuator do not become too large.
  • the cable pull is directly over by a strongly progressive pulley the articulation point of the pulley is strongly deflected, causing the cable pull in a guide tube enters at an angle and thus also due to the changing Entry angle is mechanically heavily loaded, which is a friction-free Operation impaired and leads to high wear.
  • the invention is therefore based on the object of a device for Provide actuation of at least one throttle valve, which a optimized especially with regard to friction and wear Transmission of motion between an actuator and a Throttle valve with a particularly progressive one at the same time Transmission behavior enables.
  • the translation device for generating the first progressive Sub-function on the actuator side a first (drive) Cam, which for example by means of a cable with the Actuator, such as a twist grip, and its effective lever on the operating angle based on a Idle position decreases in the direction of an upper load range, so that a large twist of the throttle grip in the lower load range relatively low throttle valve adjustment and therefore good meterability causes a lower twist in the middle and upper load range of the throttle grip requires a relatively large throttle valve adjustment.
  • the effective lever is defined by the current distance of the Approach point of the cable to the axis of the cam accordingly the distance from the curve surface to the curve axis.
  • the progression of the first (drive) Cam through a second throttle valve side (output) Cam which directly or, for example, by means of a cable with the interposition of a transmission element with the Throttle valve is connected and to generate the second progressive Subfunction serves, supported in the same direction, with the effective lever of second (output) cam plate on the throttle valve side Operating angle starting from the neutral position in the direction of the upper load range increases.
  • the first and second cam disc rotatably relative to each other, but together rotatable, coaxially mounted on a shaft and the second cam is for transmission of motion to the throttle valve, for example by means of a cable, with a coaxial with the throttle valve shaft and non-rotatable connected transmission element connected, which is pot-like is formed and the outer edge of the second cam ring surrounds.
  • the second is expedient Cam integrated in this and as a double cam with two Curves, whose effective lever based on the operating angle from increase the idle position in the direction of the upper load range, educated.
  • FIG. 1 shows a device 100 for actuating a throttle valve 108 an internal combustion engine not shown here by means of a Throttle twist grip 102 shown.
  • a Throttle twist grip 102 Such facilities can be found typically on motorcycles, with the throttle grip 102 is tubular, cylindrical and about its longitudinal axis is rotatably arranged at the outer end of a handlebar.
  • the throttle grip 102 is in an idle position corresponding to an unactuated position restoring force held against a stop. An actuation takes place by turning the throttle grip 102 counter to the Restoring force.
  • a cable pulley 104 is connected coaxially to the throttle grip 102, which circumferentially receives the end of a cable pull 106 and together with the twist grip 102 is rotatable. Starting from the idle position is the cable pull 106 when the pulley 104 rotates on the Rope pulley 104 wound up against the restoring force and thus shortened, so that the throttle valve 108, with which the cable 106 at least is indirectly connected, is pivoted in the opening direction.
  • the Restoring force is, for example, by means of a spring which acts on the Throttle valve 108 acts in the closing direction, applied.
  • throttle valve 108 is used for regulation of a gas volume flowing into the cylinder, with an admixture the fuel takes place, for example, by injection into the intake manifold.
  • Figure 2a shows a device 200 with two cams 204, 206 for Actuation of at least one throttle valve, not shown here from the front, a plan view is shown with Figure 2b.
  • a cable pull 202 is connected to the drive cam 204, which by means of an actuating device, such as a twist grip, in the pulling direction can be actuated.
  • the drive cam 204 has a usual progression on, the attack of the cable pull 202 on the drive cam 204 when actuated in the direction of a larger throttle valve opening angle with a smaller lever.
  • the Drive cam 204 corresponding to a lateral surface decreasing distance from the axis of rotation 208.
  • the drive cam 204 is coaxial with another one arranged output cam 206 rotatably connected and with this rotatably mounted together on the axis 208.
  • Output cam 206 is a cable pull 210 for actuating the Throttle valve connected.
  • the output cam plate 206 has one of the drive cam plate 204 opposite, but in terms of the overall transfer function in the same direction, reinforcing the progression, acting progression, whereby the attack of the cable 210 on the driven cam 206 at one Actuation in the direction of larger throttle valve opening angles with a lever increases.
  • the output cam plate 206 a lateral surface with a correspondingly increasing distance from the axis of rotation 208 on.
  • Throttle valve opening angle becomes a special progressive overall transmission behavior on the one hand by attacking the cable pull 202 the drive cam 204 with a decreasing lever and on the other hand by an attack on the cable 210 on the Output cam 206 reached with a larger lever.
  • Both the progression of the drive-side cam 204 and the Opposing progression of the cam disc 206 on the output side form sub-functions of an overall transfer function, which are based good meterability from an idle position in the lower load range corresponding to a relatively small throttle valve movement at one predetermined actuation of the throttle grip and in the direction of a middle and upper load range an increasingly faster response corresponding to an increasing throttle valve movement at a allows predetermined actuation of the throttle grip.
  • the lateral surfaces of the cam plates 204 and 206 are on top of one another designed so that two sub-functions the desired Represent overall transfer function of the actuating device 200 and an overall very large progression without the usual disadvantages is achievable.
  • the short cable 210 is in the further course for actuating the Throttle valve connected to a transmission element 212, which is pot-shaped and the edge of which the output cam 206th surrounds like a ring.
  • the transmission element 212 is concentric with and rotatably with the throttle valve shaft 216, which is offset to the shaft 208 is arranged, connected.
  • FIG. 2c shows a device 220 for actuating a plurality of throttle valves, where a cable distribution is integrated.
  • the cam plate on the output side is diametrical as a double cam 207 with two each other opposite points of attack for two wire rope hoists 222 and 224 educated; the design of the lateral surfaces corresponds to that with FIG. 2a . described
  • the transmission of motion to the throttle valve shafts takes place via further cams 214, which, if necessary, the Progression further intensified.
