Embodiment Construction

[0025] figure 1 A two-wheeled frame for an assist bicycle is shown. The two-wheeled frame has two frame half-shells 1, 1' made of plastic (see especially Figure 2 to Figure 5 ), which are produced by means of the injection molding process. The frame half-shells 1, 1' are forming a plurality of internal cavities 2 (see for example Figure 1a , 1b ) form the supporting frame 3 under the situation. The support frame 3 therefore has an inner parting surface 4 (see especially figure 2 , 3 ), the two frame half-shells 1, 1' abut against each other on the inner separating surface. as from Figures 1 to 5 It can be seen from the comparison that the support frame 3 has a handlebar tube receptacle 5 , a bottom bracket receptacle 6 and a driver's seat tube receptacle 7 . On its rear end viewed along the direction of travel z, the support frame 3 has a image 3 and 6c The rear structure 8 of the rear wheel 9 clearly shown in . To form the rear structure 8 a left strut 10 seen...

Abstract

The invention relates to a two-wheeled vehicle frame with two frame half-shells (1, 1') which are joined so as to form a support frame (3), thereby forming at least one inner cavity (2). The support frame (3) has at least one separating surface (4) on which the two frame half-shells (1, 1') rest against each other. The support frame (3) preferably has receiving areas (5, 6, 7) for a handlebar tubeand / or a bottom bracket and / or an operator seat tube. The support frame (3) forms a rear structure (8) for assembling a rear wheel (9) at the rear end when seen in the travel direction (z). In orderto form the rear structure (8), a left-hand support brace (10) when seen in the travel direction (z) and a right-hand support brace (11) when seen in the travel direction (z) are provided such that the rear wheel (8) can be mounted between the two support braces (10, 11). According to the invention, the separating surface (4) runs between the two frame half-shells (1, 1') as well as through the left-hand support brace (10) and through the right-hand support brace (11).

Description

technical field [0001] The invention relates to two-wheeled vehicle frames (Zweiradrahmen), especially for assisting bicycles (Pedelec), [0002] - having two frame half-shells joined together forming at least one internal cavity to form a support frame, [0003] - wherein the support frame has at least one inner parting surface against which the two frame half-shells rest against each other, [0004] - wherein the support frame preferably has a receptacle for a handlebar tube and / or a bottom bracket and / or a driver's seat tube, [0005] – wherein the support frame forms, at its rear end as viewed in the direction of travel, a rear structure for mounting the rear wheels, and [0006] - where, to form the rear structure, a left strut seen in the direction of travel and a right strut seen in the direction of travel are provided so that the rear wheels can be mounted between the two struts. Background technique [0007] The difference between a power assist bike and a normal...
