Definitions
- the invention relates to a rim brake according to the type of the main claim.
- the cable of the brake cable leads to one of the two brake brackets, namely via a roller, the axis of which is connected to the other brake bracket via a fork piece and a rope piece.
- the cable is tightened, the cable is moved a little with the roller in order to pivot the brake bar connected to the cable, the length between the roller support and the brake bar being shortened.
- the unchanged distance from the roller to the other brake bracket thus causes a certain displacement of the roller axis and thus of the center of force of this dividing device.
- rim brake serves as a dividing device, a support plate which is carried by the cable for the braking process and lead from the two articulation brackets to a brake bracket.
- actuating forces decrease as the displacement of the support plate increases, i.e. as the swivel travel of the brake brackets increases, as the angles between the Remove both transmission levers and thus also the effective adjusting force in this triangle of forces.
- the tensile force of the brake cable on the pivot axis of the brake bracket which leads to the above-mentioned additional load in the wrong direction.
- the rim brake according to the invention with the characterizing features of the main claim has the advantage that the division of forces takes place within the lifting bracket, without additional load on the axles or bearings of the brake bracket and without a one-sided displacement of the device.
- the brake pads are pressed evenly on the two sides of the rim, since the dividing device can easily adapt to the position of the rim.
- a very important advantage of the invention is that when the brake cable is actuated there is no change in the actual braking forces, at least no decrease in these forces.
- rollers serve as transfer bearings.
- it could also be static bearings, such as plain bearings, in particular plastic bearings for guiding the cables.
- only one rope connects the two brake brackets, which is clamped to the coupling piece in the middle length range.
- the position of the coupling piece relative to the two brake brackets can be adjusted very easily, since the fastening points of the rope on the brake brackets can either be such that the rope can be attached to one of the brake brackets via a head and jammed on the other brake bracket is, or that for the basic adjustment, the rope is first jammed on the two brake brackets and then the coupling part is adjusted.
- the lifting bracket is designed as a triangular frame, in the inner recess of which the coupling part is arranged, the connection of the brake cable at one of the corners and the two moving bearings being located at the other two corners of the triangular frame. Since the brake cable leads directly to the triangular frame, the jacket tube is supported on this triangular frame, while the traction cable continues to the coupling piece. The supporting forces occurring when the pulling rope is moved on the tubular casing are thus transmitted directly to the triangular frame, so that the entire force conversion operation takes place within this triangular frame.
- At least the last section of the brake cable towards the lifting bracket is designed as a pull cable guided in a tube.
- the lifting bracket can also be attached to the bicycle frame, so that the traction cable or, for example, a hydraulic device is selected for adjustment, with no forces occurring on the lifting bracket.
- the lifting bracket is freely arranged and fixed in the direction of the brake cable in the direction of the brake cable, wherein it is suspended on the lifting tube of the cable.
- the brake cable is fixed to the bicycle in order to fix the stroke.
- brake brackets 3 are pivotally mounted on pivot axes 2, on which brake pads 4 are arranged, which interact with the friction surfaces 5 of a rim 6 on which a wheel tire 7 is arranged.
- the ends 8 of the brake bracket 3 facing away from the pivot axes 2 are connected to one another by a rope 9.
- the cable 9 is guided over an adjusting force converter 11 which has a triangular frame 12 and a coupling part 13 arranged in the inner recess thereof, through which the cable 9 is guided and is fastened by means of a clamping screw 14.
- deflection rollers 15 are arranged, over which the rope 9 is guided.
- the coupling part 13 is also connected to a pull cable 16 fed from above.
- the pull cable 16 is fastened to the coupling part 13 by means of clamping screws 17.
- the traction cable 16 is guided in a casing tube 18, one end 19 of which is supported on the upper corner of the triangular frame 12 and the other end 21 of which is supported on a support 23 of a brake lever 24 arranged on an only indicated handlebar 22.
- the casing tube 18 is also connected near the triangular frame 12 to the bicycle frame via a carrier bracket 25, in order thereby to achieve flexible mounting of the adjusting force converter 11. This will avoided that the triangular frame 12 is pulled upwards when the pull cable 16 is actuated.
- the rim brake according to the invention works as follows: as soon as the cable 16 and thus the coupling part 13 is pulled upwards within the triangular frame 12 by the brake lever 24, the cable 9 is pulled along via the rollers 15 and the brake bracket 3 is pivoted relative to one another so that the brake blocks 4 get on the friction surfaces 5 of the rim 6. Due to the implementation via the rollers 15 and their unchanged position during the braking process, there is no outward force change in the area of this adjusting force converter 11. The deflection point of the rope 19 on the rollers 15 remains constant. Depending on the position of the adjusting force converter 11 in relation to the upper ends 8 of the brake bracket 3, there can even be a certain improvement in the tensile forces acting on the brake bracket 3 via the cable 9.
