Definitions

  • the present invention relates to a motorcycle according to the preamble of claim 1.
  • Modern vehicles are often equipped with a so-called driving stability system, which on the basis of various driving condition signals, such. B. wheel speeds, lateral acceleration, yaw rate, etc. permanently monitors the actual driving condition and stabilized upon detection of a critical driving condition, the vehicle by an active braking and / or gas intervention.
  • driving stability systems known from the field of four-wheeled vehicles are not transferable to motorcycles. If the motorcycle is in an unstable transverse force state, the vehicle usually can not be stabilized by a braking intervention.
  • the object of the invention is to provide a motorcycle whose chassis is designed so that in critical driving situations a stabilization of the driving condition by an electronic control intervention is possible.
  • the starting point of the invention is a motorcycle, with a fork-like wheel carrier, at the lower end of a front wheel is mounted.
  • a handlebar is provided by means of which the wheel carrier while driving in a steering direction, ie can be steered to the left or to the right
  • the handlebar is coupled to the wheel carrier by means of a "transmission device".
  • the transmission device is intended to transmit the steering forces introduced by the driver into the handlebars on the wheel carrier and to bring this into a corresponding steering position.
  • the essence of the invention is that the wheel carrier is arranged so that it is pivotable with respect to the handlebar. Pivoting in this context means that the wheel carrier at a given handlebar position at least to some extent in the steering direction, d. H. can be pivoted to the left or to the right relative to the handlebar. This additional degree of freedom allows you to drive through a driving stability system while driving. H. steering intervention controlled by driving stability electronics, that is to say a "correction" of the steering position of the wheel carrier, without the driver setting the position of the handlebar being changed, ie the driver does not need to be moved during a steering intervention.
  • the transmission device to an actuator, by means of which the wheel carrier can be pivoted while driving in relation to the handlebars.
  • the actuator may be, for example, a hydraulic cylinder, a pneumatic cylinder, an electric motor, or another actuator that responds quickly and accurately.
  • Such a steering intervention can be controlled by a monitoring electronics which, while the motorbike is moving, have at least one, preferably
  • the wheel carrier on a left and a right fork arm which are connected to each other in the region of their upper ends by a "connecting portion” or by a separate “connector”, which can also be referred to as the upper fork bridge.
  • the fork arms are fixedly connected to this connecting piece or to this "fork bridge.”
  • the link is pivotally arranged with respect to the fork bridge, which, viewed kinematically, is arranged between the link and the wheel carrier, which causes the wheel carrier to pivot relative to the link
  • the handlebar can be mounted directly on the fork bridge.
  • the wheel carrier can be a telescopic fork with two forked spars, each having two telescoping fork tubes, or a one-piece, z. B. in the form of a casting produced wheel carrier.
  • the wheel carrier can be suspended from the rest of the motorcycle via one or two so-called “trailing arms", similar to the one known on the market with “Telelever front suspension” and “Duolever front suspension” BMW motorcycles.
  • Front suspension the two lower fork tubes of the telescopic fork are connected to each other via a lower fork bridge and the lower fork bridge is connected via a centrally located in the region between the two fork arms ball joint with a lower trailing arm, whose rear ends are pivotally mounted on the frame or on the motor housing
  • the upper fork tubes of the two fork legs are over ball joints
  • 17211 B-1.rtf mounted in an upper fork bridge, which in turn is pivotally connected to the frame of the motorcycle.
  • a one-piece wheel carrier made in the form of a casting which is hinged to the frame or engine housing via lower and upper trailing links.
  • Figure 1 is a perspective view of a wheel carrier according to the
  • Figure 2 is an enlarged view of the wheel carrier of Figure 1 in the region of the upper fork bridge.
  • Figure 1 shows a front suspension 1 of a motorcycle not shown here with a telescopic fork 2, which has a left and a right fork leg.
  • the two fork legs each have a lower fork tube 3, 4 and a relatively displaceable upper fork tube 5, 6.
  • a front wheel 7 is mounted.
  • the two upper fork tubes 5, 6 are interconnected by a lower triple clamp 8 and an upper triple clamp 9.
  • the two fork bridges 8, 9 are connected to one another here via a so-called "head tube” 10.
  • the telescopic fork 2 is pivotable via the upper triple clamp 9 and / or via the lower triple clamp 8 and / or via the control tube to a frame (not shown here) stored the motorcycle.
  • the telescopic fork 2 can also be mounted on trailing arms on the frame or on the motor housing of the motorcycle.
  • the manner in which the fork is suspended on the rest of the motorcycle is of subordinate importance to the invention.
  • a handlebar 11 is disposed on the upper fork bridge 9.
  • the link 11 is connected to the upper fork bridge 9 via a pivot joint 12.
  • the link 11 can thus be pivoted relative to the upper fork bridge 9 or to the telescopic fork 2.
  • the handlebar 11 has a forwardly extending arm 13 which is connected to a piston rod 14.
  • a piston not shown in detail is arranged in each case.
  • the two pistons are displaceable in associated cylinders 15, 16.
  • the arrangement formed by the piston rod 14, the pistons and the cylinders 15, 16 acts as an actuator with which the telescopic fork 2 can be pivoted relative to the handlebar 11.
  • the actuator is controlled by a not shown here electronics.
  • the electronics monitors various driving status signals, such. B. wheel speed signals, yaw rate, banking angle, etc. If the monitored driving condition signals indicate the presence of a critical driving situation, a steering intervention can be made by means of the actuator, d. H. the telescopic fork 2 can be pivoted relative to the driver's predetermined steering position to stabilize the driving condition of the motorcycle.
  • FIG. 2 shows an enlarged representation of the front wheel suspension in the region of the actuator or of the link 11.

Abstract

Motocyclette, comprenant : un support de roue (2) en forme de fourche sur l'extrémité inférieure duquel une roue avant (7) est montée ; un organe de braquage (11) au moyen duquel le support de roue (2) peut être tourné à gauche ou à droite dans un sens de braquage pendant la conduite ; un dispositif de transmission (13-16) par lequel l'organe de braquage (11) est couplé au support de roue (2), le dispositif de transmission (13-16) étant prévu pour transférer des forces de braquage introduites dans l'organe de braquage (11) sur le support de roue (2) et amener celui-ci dans une position de braquage correspondante. Le support de roue (2) est disposé de manière à pouvoir pivoter par rapport à l'organe de braquage (11) et de manière à ce qu'avec une position de braquage prédéfinie le support de roue (2) soit mobile par rapport à l'organe de braquage (11) au moins dans une périphérie donnée dans la direction de braquage.
