Description

  • The present invention relates to a motorcycle with a transmission according to the preamble of claim 1 ,
  • Such a motorcycle is from the DE 10 2005 040 870 A1 known. The technical background of the invention include the DE 24 45 241 A1 . US 2010 0043596 A1 as well as Stoffregen, Jürgen: Motorradtechnik [Electronic Resources]. 7th, revised and expanded edition. Wiesbaden: Vieweg + Teubner, 2010. ISBN: 9783834893789 and Naunheimer, Harald; Bertsche, Bernd; Lechner, Gisbert: vehicle transmission. 2nd, edit and erw. Aufl. Berlin [ua]: Springer [ua], 2007. ISBN: 978-3-540-30625-2.
  • Numerous BMW motorcycles are equipped with an unsynchronized claw transmission, which has five or six gears. To further improve the dynamic characteristics while reducing fuel consumption, transmissions with more than six gears are considered.
  • The object of the invention is to provide a motorcycle with an unsynchronized claw transmission having at least seven gears, wherein the transmission in the transverse direction of the motorcycle should have substantially the same width as a conventional six-speed transmission.
  • This object is achieved by the features of the claim 1 solved. Advantageous embodiments and further developments of the invention can be found in the dependent claims.
  • The starting point of the invention is a motorcycle with an unsynchronized claw transmission with at least seven gears, wherein the transmission has an input shaft driven by a drive motor via a clutch, an output shaft and, viewed in the transverse direction of the motorcycle, six gear stages arranged one behind the other. Each of the gear stages has a gear arranged on the input shaft and a gear arranged on the output shaft, which mesh with each other. In six of the at least seven gears of the claw transmission, torque is transmitted from the input shaft directly to the output shaft via a gear stage associated with the gear in question.
  • The essence of the invention is not to represent the seventh gear via a further "laterally next to" the six gear stages arranged gear stage, but via a "third wave". The third shaft is arranged parallel to the input and output shafts. At least two gears are arranged on the third shaft, and in the seventh gear, torque is transmitted from a gear arranged on the input shaft via a gear arranged on the output shaft to one of the gears arranged on the third shaft and from this to another one on the third shaft arranged gears and these in turn is transmitted via a arranged on the output shaft gear to the output shaft. By adapting the gear housing can be derived with relatively little effort from a conventional six-speed gearbox a seven-speed or eight-speed gearbox.
  • In the following the invention will be explained in connection with the drawing. The only 1 shows a highly schematic of a transmission scheme for an unsynchronized claw transmission according to the invention.
  • 1 shows an unsynchronized claw transmission 1 with an input shaft 2 , by a drive motor not shown here via a (also shown only very schematically) coupling 3 is drivable. The claw gearbox 1 also has an output shaft 4 on which a sprocket 5 is arranged, and a "third wave" 6, which is parallel to the input shaft 2 and the output shaft 4 is arranged.
  • How out 1 it can be seen has the claw transmission 1 six in the transverse direction of the motorcycle, ie in the longitudinal direction of the input or output shaft 2 respectively. 4 , arranged gear stages 7 - 12 on. Each of the gear stages 7 - 12 again indicates on the input shaft 2 and one on the output shaft 4 arranged gear on. The gear stage 7 has a rotationally fixed and immovable on the input shaft 2 arranged gear 13 on which with a rotatable on the output shaft 4 stored gear 14 combs. The gear stage 8th has a rotationally fixed and immovable on the input shaft 2 arranged gear 15 on which with a rotatable on the output shaft 4 arranged gear 16 combs.
  • The gear stage 9 has a rotation with the input shaft 2 coupled gear 17 on, with the gear 17 slidable on the input shaft 2 is arranged. The gear 17 meshes with a rotatable on the output shaft 4 arranged gear 18 ,
  • The gear stage 10 has a rotation with the input shaft 2 coupled gear 19 on which slidably on the input shaft 2 is arranged and rotatable on the output shaft 4 stored gear 20 combs.
  • The gear stage 11 has a rotatable on the input shaft 2 arranged gear 21 on, which with a rotation with an output shaft 4 coupled gear 22 meshes, sliding on the output shaft 4 is arranged.
  • The gear stage 12 has a rotatable on the input shaft 2 stored gear 23 on, with a non-rotatable with the output shaft 4 coupled gear 24 meshes, which slidably on the output shaft 4 is arranged.
  • On the third wave 6 is a rotation with the third wave 6 coupled gear 25 arranged, which slidably on the third wave 6 is. Next to the gear 25 is on the third wave 6 a gear 26 rotatably mounted. The gear 25 meshes with the gear 20 and the gear 26 meshes with the gear 24 ,
  • The following is the operation, ie, the individual gears of the claw gear 1 explained.
  • When the first gear is engaged, torque is transmitted from the drive motor via the clutch 3 on the input shaft 2 and further from the gear 13 on the gear 14 and from this via a shift claw 27 on the gear 22 and from this in turn to the output shaft 4 transfer. When engaged first gear is the gear 22 shifted to the right, leaving its shift claw 27 in a dog teeth of the gear 14 intervenes.
  • When engaged second gear is torque from the input shaft 2 over the gear 15 on the gear 16 and from this via a shift claw 28 on the gear 24 and the gear 24 on the output shaft 4 transfer. The gear 24 is shifted inlaid second gear to the left, so that its shift claw 28 in a dog teeth of the gear 16 intervenes.
  • When engaged third gear is torque from the input shaft 2 over the gear 17 on the gear 18 and continue via a shift claw 29 on the gear 22 and from this to the output shaft 4 transfer. When engaged third gear is the gear 22 shifted to the left, leaving its shift claw in a claw toothing of the gear 18 intervenes.
  • When fourth gear is engaged, torque is transmitted from the input shaft 2 over the gear 19 on the gear 20 and further via a dog toothing 30 on the gear 24 and from this to the output shaft 4 transfer. When engaged fourth gear is the gear 24 thus shifted to the right, so that its shift claw 30 in a dog teeth of the gear 20 intervenes.
  • When fifth gear is engaged, torque is transmitted from the input shaft 2 over the gear 17 and a dog tooth system 31 on the gear 21 and from this about the gear 22 on the output shaft 4 transfer. The gear 17 is shifted to the right, so that its shift claw 31 in a dog teeth of the gear 21 intervenes.
  • When engaged sixth gear is torque from the input shaft 2 over the gear 19 and a shift claw 32 on the gear 23 and from this about the gear 24 on the output shaft 4 transfer. When engaged sixth gear is the gear 19 thus shifted to the left, so that its shift claw 32 in a dog teeth of the gear 23 intervenes.
  • How out 1 It can be seen that the two gears are 17 . 19 coupled together so that they can only be moved simultaneously to the left or right.
  • When engaged seventh gear is torque from the input shaft 2 on the gear 19 and from this on over the gear 20 on the gear 25 transfer. When engaged seventh gear is the gear 25 shifted to the left, leaving a shift claw 33 of the gear 25 in a dog teeth of the gear 26 intervenes. The two gears 25 . 26 turn synchronously. From the gear 26 the torque will continue on the gear 24 and from this to the output shaft 4 transfer.
  • In addition to the gear 26 could be on the third wave 6 be arranged a further gear, then in addition an eighth gear could be displayed. By such a modular design, different model variants can be represented with different gear ratios within an engine / transmission family, and with unchanged gear width.
  • As already mentioned, all "switching elements" are designed as claw switching elements without synchronizing, which has the advantage that gear changes can be carried out very quickly.
  • To move the switchable gears 17 . 19 . 22 . 24 . 25 in the axial direction of the associated shaft 2 . 4 respectively. 6 , a shift drum may be provided. The shift drum has an axis of rotation parallel to the shafts 2 . 4 . 6 is. By turning the shift drum, in which associated drivers engage, the shift wheels 17 . 19 . 22 . 24 . 25 on their respective axis 2 . 4 respectively. 6 moved and thus the individual gears are switched.
  • The shift drum is coupled via a kinematics with a laterally arranged outside of a motor / gearbox housing shift lever.
