Abstract: A stop for handlebars of two-wheeled vehicles is integrated into the control head bearing of the vehicle. It is formed by a first component installed in the control head bearing with a circular arc-shaped groove that is arranged coaxially to the rotational axis of the control head bearing and a stop element protruding into this groove. The stop element is arranged on a second component that can be moved relative to the first part. The stop at the lower control head bearing is arranged within the head tube. The circular arc-shaped groove is arranged in the base and open towards the lower bearing shell. The lower bearing shell comprises an open recess extending over its height to the lower rolling bearing, which receives a stop element. The stop element has a radial lug protruding into the circular groove of the base.

Abstract: The invention proceeds from a steering device for two- and three-wheeled vehicles, which ensures a rotationally fixed connection between handlebars and a handlebar stem and/or between a handlebar stem and a fork of the two- or three-wheeled vehicle, and a steering device for two- and three-wheeled vehicles having a stop. The steering device has a frame with a head tube (1), a fork (2) with a stem tube (3) and a handlebar stem (4) with handlebars (7). In addition, a stop can be provided for the handlebars (7), which consists of a base (12), which is connected in a rotationally fixed manner to the fork (2) of the two- or three-wheeled vehicle, with a recess (14) and a stop element (15), which is securely arranged in the bearing shell (11) and protrudes radially into the recess (14).
According to the invention, in each case one component of the rotationally fixed connection has a smooth cylindrical surface over its axial length, whilst the surface, which is in frictional operative connection with this smooth cylindrical surface in the mounted state, of the other component, which is arranged coaxially to that first-mentioned, is constructed as an n-sided polygon.-

Abstract: A device for adjusting the bearing play of components mounted coaxially rotatable to one another and rotatably joined to one another via two axially separated roller bearings is operatively connected to one roller bearing by an end side and to a counter bearing by the opposing end side. The device is formed by two coaxially adjacent rings on one of the components. Each opposing end surface thereof has at least one contour projecting from the plane of the end surfaces. At least one contour has an incline on which the at least one opposing contour slides. One ring is operatively connected to the counter bearing by the other end surface. The other ring is operatively connected to the roller bearing. A device for mutual radial rotation and a device for locking the axially moving ring in the assumed axial position are on both rings.

Abstract: A centring ring (5) and a method for reducing the risk of breakage of at least one thin-walled area of a centring ring (4) are proposed, the centring ring (5) having at least two thick-walled segments, i.e. at least one first thick-walled segment (15) and one second thick-walled segment (16), said first thick-walled segment (15) having a side surface (23) which faces a side surface (31) of the second thick-walled segment (16), said side surfaces (23, 31) touching each other at least partially or being separated from each other by a gap (37) having a given clearance B (38), and said centring ring (5) including at least one movement limiter (24, 48) which allows the side surfaces (23,31) to merely drift apart under the application of force and/or drift towards each other under the application of force until a certain clearance B (38) is reached.

Abstract: A device for adjusting the bearing play of components that are mounted such that they can rotate coaxially in relation to one another, which components are rotatably joined to one another via two roller bearings arranged at an axial distance to one another, is operatively connected to one of the two roller bearings by an end side, and is operatively connected to a counter bearing by the opposing end side. The device is formed by two rings that are arranged next to one another, in a coaxial manner on one of the components. The opposing end surfaces thereof each have at least one contour projecting from the plane of the end surfaces. At least one of the contours is provided with an incline on which the at least one opposing contour slides. One ring is operatively connected to the counter bearing by the other end surface, and the other ring is operatively connected to the roller bearing. A device for the mutual radial rotation and a device for the locking of the axially moving ring in the assumed axial position are provided on both rings.
