To solve this problem, the invention proposes a cable drive for a throttle flap of a vehicle, in particular a vehicle with a handlebar with two handles such as primarily in an ATV, UTV, jet ski, snowmobile or two-wheeler, which is provided with

• a housing having a first housing part and a second housing part,
• a first drive disk rotatably mounted in the first housing part and connectable to a pivot shaft of a throttle valve, wherein the first drive disk is rotatable by a first cable from an idling gas position to a full throttle position and resiliently biased towards its idling gas position,
• - A rotatably mounted in the second housing part second drive pulley, which is rotatably biased by a second cable from a Leerlaufgasstellung in a full throttle position and resiliently biased toward their idling gas position, and
• - A driver element through which the two drive disks are selectively in rotational engagement, by
  • - The second drive pulley remains in its idle gas position when the first drive pulley is rotated, and
  • - The second drive pulley rotates the first drive pulley by means of the driver element in its rotation from the idle gas position in the direction of its full throttle position.

The cable according to the invention for the throttle flap of a vehicle with a handlebar provided with two handles can be activated by one of two cable pulls. Here, the cable drive on a two-part housing, in the first housing part a rotatably mounted first drive pulley is arranged, which, as known in cable pull drives for throttle valves per se, connected to the pivot shaft of a throttle or connected. This first drive pulley is rotated by a first cable from an idle throttle position to a full throttle position, wherein the first drive pulley is resiliently biased toward its idling gas position.

According to the invention, such a cable drive housing is provided with a second drive pulley, which by a second cable from an idling gas position into a full throttle position rotatable and is also resiliently biased toward their idle gas position. The two cables can lead starting from the housing to the two handles of the handlebar of the vehicle equipped with the throttle cable drive according to the invention.

According to the invention, the two drive disks can be selectively brought into rotational engagement, with the aid of a driver element. The driver element is mounted on one of the two drive pulleys and takes with rotation the other drive pulley or the other drive pulley takes over the driver element with a drive pulley. This is done according to the invention in such a way that the one drive disk remains in its idle gas position, when the other drive pulley rotates, and that the one drive pulley rotates the other drive pulley by means of the driver element in its rotation from the idle gas position toward the full throttle position.

The driver element is a coupling element with which the two drive disks are selectively rotationally coupled. Normally, the driver element is located on the second drive pulley and is located on a projection, a recess or the like. the first drive pulley.

The cable pull drive concept according to the invention for the throttle flap of a vehicle is particularly advantageous from the aspect that an existing single-throttle cable drive can be converted as a double cable drive. The housing of a single-cable drive for the throttle valve of a vehicle is usually the first drive pulley. The housing is or the like by means of a lid. locked. Now, if this cover is removed and instead of this cover another housing part with the second drive pulley, which is provided with the driver, closed, so now the first drive pulley can be rotated via the driver, when the second cable is operated for the second drive pulley. The first drive pulley is the one that is fixedly connected to the pivot shaft of the throttle valve. This drive pulley can now be rotated in two ways, namely when only the first cable pull and only the second cable pull.

If the first cable pull is actuated, only the first drive pulley rotates, while the second drive pulley preferably stands still over the entire rotational travel of the first drive pulley, namely remains in its idling gas position. This can be done, for example, by a circumferential projection or a circumferential recess on the first drive disk or on one of the drive disks. At an Anlagerandabschnitt this Aussparrung or the circumferential projection then lies on the driver element. In this embodiment of the invention is thus provided with advantage that one of the drive pulleys has a recess which extends in the circumferential direction of the drive pulley and is limited relative to the circumferential direction by an abutment edge portion and a further edge portion, wherein the Anlagerandabschnitt upon rotation of a drive pulley whose idle gas position in the full throttle position the other edge portion seen in the direction of rotation voruseilt that the driver is disposed on the not provided with the recess other drive pulley and protrudes into the recess of a said drive pulley and that the driver then, when both drive pulleys in their respective Leerlaufgasstellung for the purpose of rotation of the drive disc not provided with the recess other drive disk rotational drive of the provided with the recess a drive pulley at the Anlagerandabschnitt the Aussp arung this drive pulley rests. If the circumferential recess extends over almost 360 °, this is tantamount to the formation of a circumferential projection on said drive pulley. In this case too, the abutment edge portion, against which the entrainment element of the other drive disk rests, rotates the drive disk provided with the recess from its idling gas position in its full throttle position to the further edge portion, i. the other radially extending edge portion of the circumferential projection, viewed in the direction of rotation, leads the way.

As already mentioned above, when the first cable pull is actuated, the second drive pulley preferably remains in its idling gas position over the entire rotation of the first drive pulley. This means that the circumferential recess extends over a corresponding minimum circumferential angle range, namely at most in the full throttle position of the recess provided with the first drive pulley on the driver element (again) to rest. Because at the beginning of the rotation of the first drive pulley, this is released from the stationary driver element, which is arranged on the remaining in the idle gas position second drive pulley. With the further edge portion of its recess now reaches the first drive pulley at most in their full throttle position on the driver element. If this happens earlier, ie before reaching the full throttle position of the first drive pulley, the second drive pulley would still be rotated, which would require an additional actuation force for the gas handle (rotary handle or throttle (thumb throttle)), since now would have to be worked against the biasing forces of both drive pulleys ,

As already mentioned above, the cable drive according to the invention advantageously offers the possibility of retrofitting a single cable drive. It is advantageous if the housing is divided into its two housing parts along a dividing plane which extends at an angle of not equal to 180 ° and in particular at an angle of 90 ° or substantially 90 ° to align the axes of rotation of the two drive disks.

1 shows the front part of an ATV 10 , whose handlebars 12 not only, as is well known, at the right end 14 a (stick or thumb) throttle 16 but at the left end 18 a corresponding throttle 20 having. From the right throttle 16 out extends a first cable 22 , to the case 24 the cable drive for a throttle valve 26 while moving from the left throttle 20 a second cable 28 to the cable drive housing 24 extends. In 2 is the throttle 26 with cable drive housing 24 again shown in perspective.

Based on 3 as well as the 4 to 6 to be discussed below on the structure of the cable drive housing 24 To be received. The housing 24 is made in two parts and has a first housing part 30 and a second housing part 32 on. The separation level 34 Both housing parts extends substantially perpendicular to the pivot shaft 36 the throttle 26 , In the first housing part 30 there is a first (rope) drive pulley 38 at the first cable 22 attacks to the first drive pulley 38 from the in 4 shown idle gas position in the in 5 respectively. 6 to turn shown full throttle position. By means of a return spring 40 is the first drive pulley 38 biased toward their idle throttle position.

In the second housing part 32 a second (cable) drive pulley 42 is arranged, on which the second cable pull 28 attacks the second drive pulley 42 from their idle gas position according to 5 in their full throttle position according to 6 to twist. By means of a return spring 44 is the second drive pulley 42 biased toward their idle throttle position.

The first drive pulley 38 is with the pivot shaft 36 the throttle 26 connected, so twisted the throttle 26 corresponding. In this respect, it forms the (rotary) drive for the throttle valve 26 , The second drive pulley 42 is via an axially projecting driver element 46 in the form of a bolt or pin, for example 48 with the first drive pulley 38 rotationally coupled. This is in 4 shown. The rotary coupling is done by conditioning the driver element 46 at the investment edge 50 a circumferential recess 52 the first drive pulley 38 , wherein the circumferential recess by a further edge portion 54 is limited. In other words, so the driver element 46 at a radial projection 56 the first drive pulley 38 at, with this radial projection 56 at the same time as an end stop to limit the rotation of the first drive pulley 38 in the full throttle position is used (see the 5 and 6 ).

In the 4 to 6 is shown in dashed lines, in which positions, the driver element 46 is located when neither of the two cables or at least one of the two cables is operated. 4 shows the situation in which the throttle 26 is in its idle position. On neither of the two cables is pulled. 5 shows the situation where the throttle is 16 is actuated, so train over the first cable 22 Train is exercised, bringing the first drive pulley 38 twisted to full throttle position.

During this phase, the second drive pulley remains 42 in their idle gas position.

Will now to accelerate the left throttle 20 operated, so train is on the second cable 28 exercised, leaving the second drive pulley 42 is twisted. About the driver element 46 the second drive pulley 42 now becomes the first drive pulley 38 turned and with it the throttle 26 pivoted. The cable 22 that is at the first drive pulley 38 attacks, is now relieved, what in 6 is indicated.

As an alternative to the drawing illustrated and previously described embodiment, the driver element 46 the second drive pulley 42 but also at the in the figures 58 shown Anlagerandabschnitt the first drive pulley 38 Attack to these while exercising by pulling on the second Bowden cable 28 to twist or to rest when on the first Bowden cable 22 is pulled. Furthermore, the second Bowden cable 28 regardless of the position of the driver element 46 , based on the 3 or the 4 to 6 , upwards or to the left, ie opposite to the first Bowden cable 22 out of the case 24 be led out (in 6 indicated by dashed lines).

The concept described here can be used to retrofit a single-cable drive of a vehicle throttle as a double cable drive. Conventional throttle valve drives have only one drive pulley, namely the first drive pulley 38 according to previous description. The housing 24 has only the first housing part 30 on, which is closed for example by a lid. This cover is now removed for retooling the single-cable drive and through the second housing part 32 replaced according to the invention, bringing now the throttle 26 can be operated via one of two cables.
