Description

Telescopic two-wheel suspension with external damping and/or spring element.

State of the art

In conventional suspension systems based on the telescopic principle, the damping and/or spring elements are located inside the standpipes and immersion tubes. To compensate for torsional forces, large wheel axle diameters and complex cross connections (so-called boosters) of the immersion tubes are used.

The suspension and/or damping elements inside the tubes are also relatively difficult to access.

invention

A reduction in the tendency to torsion with small tube diameters and easily accessible suspension and/or damping elements of a telescopic suspension fork is achieved by the measures presented in claims 1 and 2.

Further developments of the inventions

An embodiment of the invention according to claims 1 and 2 allows the easy exchange of different damping and/or spring elements. Blocking and/or adjustable damping and/or spring elements can be used from the handlebar.

In addition, when using the same components, different geometries and different spring travels can be realized depending on the connection height of the cross members.

Depiction

Fig. 1 shows a perspective view of a telescopic suspension fork in which the spring and/or damping element (9) is mounted between a cross member (8) of the fork tubes (6,7) and a cross member (4) of the stanchion tubes (1,2) in front of the steerer tube (10).

Fig. 2 shows the individual parts of a telescopic suspension fork with external spring and/or damping element.

(6,7) the fork tubes with the dropouts for the wheel axle mount, (13,14) brake bases for cantilever brakes.

The cross connection (8) of the immersion tubes and the cross connection (4) of the standpipes have a base (15/16) for fastening the damping and/or suspension elements (9).

(3,5) represent the two fork backs that connect the stanchions (1,2) with the steerer tube (10). (17,18,19,20) are plain bearings between the stanchions and fork tubes.

Fig. 3 shows a front view and Fig. 4 a side view of a telescopic suspension fork with external damping and/or spring element (9).

Fig. 5 and Fig. 6 show two variants of a telescopic suspension fork with external damping and/or spring element.

Apart from the different damping and/or spring elements, the same components are used, only the stanchions and the fork shaft are shortened to the appropriate length. With large spring travel, the upper cross connection (4) for the damper mount can be located above the fork bridge (3,5) to connect the stanchions to the fork shaft, as shown in Fig. 6.

Claims (2)

Suspension fork Page 1 Klaus Kramer, Dorfstraße 16b, 79294, Sölden Protection claims 1. Wheel suspension for the spring-loaded mounting of the wheel, in particular the front wheel of a two-wheeler, which has two tubes on both sides of the wheel which are mounted in one another so as to be displaceable in their longitudinal extension, the inner tubes (1, 2) having at least one, in the application three rigid cross-connections (3, 4, 5) and the outer tubes (6, 7) having at least one cross-connection (8) in addition to the wheel axle, characterized in that that at least one damping and/or spring element (9) engages between one of the cross connections (4) of the inner tubes (1,2) and at least one of the cross connections (8) of the outer tubes (6,7). 2. Wheel suspension according to claim 1,
characterized, that the inner tubes (1,2) have a greater wall thickness in sections and/or have reinforcing elements that completely or partially fill the tube cross-section in sections or over the entire longitudinal extent.
