Definitions
- the present invention relates to a front wheel suspension for motorcycles according to the preamble of claim 1.
- the "K1200 S” motorcycle from BMW has a front suspension known as "Duolever”.
- the Duolever front suspension is a four-bar linkage, which is formed by two superimposed, each pivotally mounted on the frame or on a motor housing trailing arm. Front ends of the trailing arms are each connected via a ball joint with a fork-like "wheel”, which is made in one piece of aluminum chill casting in the K1200 S.
- the suspension and damping takes over a strut, which is hinged to the lower of the two trailing arms and against the frame
- a trapezoidal scissor joint mounted on the "steering head” and wheel carrier is coupled to the handlebar and transmits the steering movements applied via the handlebar to the wheel carrier.
- Ball joints are at the transition of static friction in sliding friction, ie when compression of the wheel carrier as well as when steering from a "rest position” out with certain, albeit small “breakaway” afflicted. In order to get into the sliding friction state, so first a slightly larger static friction moment must be overcome.
- the object of the invention is to provide an improved “Duolever front wheel suspension” in which "breakaway torques" do not occur.
- the starting point of the invention is a "Duolever front suspension" for motorcycles with a fork-like wheel, which has a left “fork arm” and a right “fork arm”, as well as a lower connecting the two fork arms together and an upper connecting element interconnecting the two fork arms
- wheel carrier is to be interpreted very broadly and includes both one-piece wheel carrier, the z. B. can be made in the form of a casting, as well as telescopic forks with a lower and an upper fork bridge.
- the wheel carrier is suspended from other "components" of the motorcycle by means of a lower and an upper trailing arm, for example, rear ends of the trailing arms may be pivoted to a frame or to a motor housing of the motorcycle.
- front ends of the trailing arm in contrast to the known from the prior art Duolever-front-wheel suspensions are not coupled via ball joints with the wheel, but via pivot bearings.
- the front end of the upper trailing arm and the front end of the lower trailing arm are each pivotally connected to the wheel carrier via a pivot bearing whose pivot axis extends substantially transversely to a longitudinal direction of the motorcycle. These pivot bearings allow spring movements of the wheel carrier with respect to the frame of the motorcycle.
- the two pivot bearings are designed as rolling bearings.
- rolling bearings are “breakaway moments" as in ball joints can occur almost completely avoided.
- the front ends of the trailing arm are connected exclusively via rolling bearings with the wheel carrier.
- a pipe extending between the upper and lower connecting elements of the wheel carrier may be provided, whose upper end is connected to the upper connecting element via an upper steering bearing and whose lower end is connected to the lower connecting element via a lower steering bearing.
- the axes of rotation of the two steering bearings are coaxial and extend in a direction which is at least approximately parallel to a longitudinal direction of the fork arms.
- the two steering bearings are formed by rolling bearings, so that even when steering the wheel carrier "breakaway torques" are substantially avoided.
- FIGURE 1 shows an embodiment according to the invention.
- the front suspension having a forked wheel carrier 1 formed by a left fork arm 2, a right fork arm 3 and a lower fork bridge 4 and an upper triple bridge 5.
- the two fork bridges 4, 5 connect the two fork arms 2, 3.
- the fork arms 2, 3 may be fork tubes of a telescopic fork.
- the wheel carrier can also be used as a one-piece wheel carrier, for. B. be formed in the form of a casting.
- the wheel carrier 1 is mounted by means of a lower trailing arm 6 and an upper trailing arm 7 on "other components" of a motorcycle not shown here, such as the motorcycle frame and / or a motor housing of the motorcycle a left trailing arm 6a and 7a and a right trailing arm 6b and 7b, respectively.
- a control tube extends 8.
- a lower end of the control tube 8 is connected via roller bearings 9 with the lower fork bridge.
- an upper end of the control tube 8 is connected via a roller bearing 10 with the upper triple clamp 5.
- the rolling bearings 9, 10 serve as a steering bearing.
- the two roller bearings 9, 10 are arranged coaxially, with their axis of rotation 11 forms the "steering axis", by which the wheel carrier 1 can be steered.
- Front ends of the trailing arm 6a, 6b and 7a, 7b are each connected via an upper and a lower pivot bearing 12, 13 pivotally connected to the control tube 8.
- the pivot bearing can also be designed as a rolling bearing.
- the pivot bearings 12, 13 enable "spring movements" of the wheel carrier with respect to the frame of the motorcycle 12.
- "breakaway torques" are created, as in a conventional Duolever front wheel suspension can occur with ball joints during compression or rebound of the front wheel or when steering the front wheel, almost completely avoided.
