Problems solved by technology

[0003] However, the problem here is that even small deviations from the straight-ahead direction of the front wheels at the time of a collision can lead to a turning of the front wheels about the vertical, which reduces the distance

Embodiment Construction

[0028]figure 1 withfigure 2 The problem of a frontal collision at the motor two-wheeled vehicle 10 in the case of a collision with the obstacle 12 along the traveling motion in the longitudinal direction L of the two-wheeled vehicle 10 is explained. This passesfigure 1 The arrow in indicates that the arrow gives the driving direction R when driving straight.

[0029]The contact with the obstacle 12 occurs at the front 13 of the two-wheeled vehicle 10, at the front side of the front wheels 14 (figure 2 ). If the front wheel 14 hits the obstacle 12 along its front direction parallel to the longitudinal direction L of the two-wheeled vehicle 10, the front wheel is provided on the obstacle 12 (more precisely, the front wheel 14 and the obstacle 12 The distance d between the contact point) and the driver of the two-wheeled vehicle 10 (not shown). However, in a conventional two-wheeled vehicle, if the front wheel 14 collides with the obstacle 12 at an angle, it may happen that the front whee...

Abstract

The invention relates to a collision protection device (16) on a motorized bicycle (10), comprising a catching element (18) which is securely mounted on a frame (32) of the bicycle (10) and has a receptacle (20) which is delimited by two guide sections (22) and is open in the direction towards a front wheel (14) of the bicycle (10). The free ends (24) of the guide sections (22) pointing in the direction of travel (R) are arranged such that they are always at a distance from the front wheel (14) during normal riding but, in the event of a front-end collision in which the front wheel (14) impacts on an obstacle (12), the front wheel (14) is pushed into the receptacle (20) beyond the free ends (24) towards the frame (32) of the bicycle (10).

Description

Technical field[0001]The invention relates to a collision protection device on a two-wheeled motor vehicle, especially a motorcycle or a moped.Background technique[0002]In the case of a frontal collision with an obstacle, the front wheel can be used to advantageously increase the distance between the obstacle and the driver. This also works in two-wheeled motor vehicles with restraint systems, such as seat belts, so as to allow enough time to be able to compatibly reduce the force acting on the driver.[0003]However, the problem here is that even a small deviation in the front direction of the front wheels at the time of a collision may cause the front wheels to rotate about the vertical line, which reduces the distance.Summary of the invention[0004]The object of the present invention is to improve collision protection in two-wheeled motor vehicles.[0005]The objective is achieved by a collision protection device having the features according to claim 1. The collision protection devic...
