Definitions
- the bridge has two projections in lower areas of the bridge.
- the lower portions of the bridge may include lower ends of the bridge.
- the lower areas of the bridge can be the areas of the bridge that are closest to the standpipes.
- Each one of the two projections can be arranged on a left and on a right bridge leg.
- the projections can be formed integrally with the bridge.
- at least one projection can be designed as a separate component and can be connected to the bridge, in particular by means of gluing, screwing, welding or pressing.
- the projections can taper downwards, ie away from the bridge. Alternatively, the projections can run straight down.
- Each protrusion has a second perimeter.
- Each protrusion of the bridge engages in one of the openings of the standpipes. Engagement of a projection with an opening can result in jamming of the projection and opening.
- the projection can be fixedly connected to the opening after engagement, for example by means of glue or screws.
- An outside of the projection and alternatively or additionally an inside of the standpipe can be shaped in such a way that the projection and the opening engage in one another in a form-fitting manner. For example, this can be done by grooving in at least one of the outside of the boss and the inside of the standpipe.
- a spring fork is thus shown in which the standpipes can be prevented from engaging in the bridge.
- the standpipes are not completely immersed in the bridge. Rather, the projections of the bridge engage in the standpipes.
- a mechanical stability of the connection between standpipes and bridge is particularly dependent on the projections. By adjusting the projections, the mechanical stability of the suspension fork can be changed when it is mounted, without having to change the design of the rest of the bridge.
- a spring fork can thus advantageously be shown, in which case an outer contour of the bridge in the lower areas and above the projections can merge seamlessly into an outer contour of each standpipe in the upper area of the standpipes.
- a transition between bridge and standpipes can be formed without a jump in diameter between bridge and standpipe.
- FIG. 1 shows a suspension fork 2 according to one embodiment.
- the suspension fork 2 has a bridge 4, a shaft 28 and standpipes 6a, 6b.
- the bridge 4 is connected to the stem 28 at an upper end of the bridge 4 .
- the bridge 4 has bridge legs 4a, 4b.
- the bridge 4 is connected to the standpipes 6a, 6b via the bridge legs 4a, 4b.
- the bridge 4 has a lower area 12a, 12b in each of the bridge legs 4a, 4b.
- the bridge 4 In the lower areas 12a, 12b of the bridge 4, the bridge 4 has a respective projection 14a, 14b.
- the bridge 4 In the lower regions 12a, 12b and above the projections 14a, 14b, the bridge 4 has a third circumference as the outer circumference on each of the bridge legs 4a, 4b.
- the standpipes 6a, 6b are designed as cylindrical tubes. Each standpipe 6a, 6b has an outer circumference. The outer circumference is equal to the third circumference and merges seamlessly into the outer circumference of each bridge leg 4a, 4b. Each of the standpipes 6a, 6b has an upper area 8a, 8b. In the upper region 8a, 8b, each standpipe 6a, 6b has an inner circumference which is equal to a first circumference. Each standpipe 6a, 6b also has an opening 10a, 10b in the upper area 8a, 8b.
- the suspension fork 2 also has rings 16a, 16b.
- the rings 16a, 16b have the third circumference as the outer circumference and the first circumference as the inner circumference.
- the rings 16a, 16b also have a thickness.
- the projections 14a, 14b each engage in one of the rings 16a, 16b.
- the projections 14a, 14b each engage in one of the openings 10a, 10b of the standpipes 6a, 6b. Due to the rings 16a, 16b, the bridge 4 and the standpipes 6a, 6b are each spaced apart by the thickness of the rings 16a, 16b.
- Each standpipe 6a, 6b has a free space 20a, 20b.
- the free spaces 20a, 20b are each formed by the cylindrical interior of a standpipe 6a, 6b.
- the free spaces 20a, 20b are connected to the free space 18 of the bridge 4.
- the ends of the projections 14a, 14b are open, so that the spaces 20a, 20b and 18 are connected.
- a line 22a leads from the free space 30 of the shaft 28 via the free space 18 of the bridge 4 into the free space 20a of the standpipe 6a.
- a line 22b leads from the free space 30 of the shaft 28 via the free space 18 of the bridge 4 into the free space 20b of the standpipe 6b.
- the bridge 4 has a cavity 24 .
- the cavity 24 is part of the free space 18. In other words, the cavity 24 and the free space 18 are connected.
- the suspension fork 2 has a pressure sensor 26 which is set up to measure pressure in the suspension fork during suspension. To measure the pressure in the suspension fork, the Pressure sensor 26 lines, not shown, from the pressure sensor 26 into the free space 20a of the standpipe 6a.
