Definitions

  • the invention relates to a road bike brake and a braking device for racing bike brakes.
  • Rim brakes have the disadvantage that the braking effect decreases in the wet. This also occurs in wintry conditions and in the formation of a snow or ice layer. Another disadvantage is that in a spoke break due to the resulting side impact in the wheel, the rim grinds on the brake bends. Furthermore, rim brakes have the disadvantage that, especially when driving downhill, there is a strong heating of the rim brakes. This leads to the release of the braking effect, It may also come due to the heating to damage or even bursting of the hoses.
  • suspension forks is not desirable for reasons of weight on racing bikes.
  • the required elasticity must be ensured in racing bikes by a correspondingly elastic front fork. Due to the elasticity, in particular of the lower region of the fork tubes pointing in the direction of the dropouts, the required traction is achieved.
  • a corresponding elasticity of the lower portion of the fork tubes is absolutely necessary for road forks, as for example at higher speeds otherwise the front wheel would take off in the case of wavy roads at short notice. This would lead to falls especially in curves. Stiffening a racing fork to provide a disc brake is therefore not possible.
  • the provision of a suspension is not desirable for weight reasons and was also when driving in the saddle lead to losses. A part of the leg strength would be lost by the compression.
  • the provision of suspension forks on racing wheels would adversely affect driving behavior. In particular, a slower steering behavior and an unwanted extension of the wheelbase would take place.
  • the object of the invention is to provide a road bike brake, as well as a braking device for racing bikes, with which a better deceleration effect can be achieved.
  • the object is achieved for a road bike brake according to claim 10 or a braking device for road bikes according to claim 1, 5 or 8.
  • the road bike brake according to the invention for front wheels has a Bremsseinrlchtung for transmitting braking forces to the front wheel.
  • the braking device Via a power transmission device, the braking device is connected to an actuating device for generating the braking forces.
  • the power transmission device thus transmits the forces from the actuator to the braking device.
  • the braking device has two brake disks.
  • One of the two brake disks is laterally connected to the outside of the front wheel hub.
  • the braking device has a hydraulically actuable Bremszyli ⁇ der.
  • the provision of a hydraulic brake in racing bicycles is possible in particular because, due to the provision of two disc brakes, the forces acting on the individual brake discs are lower than in the provision of only a single brake disc. This has the advantage that the forces and moments transmitted to the individual fork tube are lower. Further, when providing two brake discs, it is ensured that the two fork tubes deform equally, with the deformation being within the allowable deformation of the material. Due to the uniform deformation of both fork arms a good handling is ensured. In providing a single disc and the associated unilateral deformation of the bicycle fork when braking, a twisting of the front wheel and thus cornering would be caused in racing bikes, which enforces a corresponding countersteering. Furthermore, the provision of two brake discs has the advantage that the two spoke sides are uniformly loaded and thus compared to the provision of only one brake disc, the risk of damaging the corresponding spoke side and the fixation of the spokes in the rims is reduced ,
  • Another important advantage of the compound is that the heat occurring during braking due to the provision of two brake discs is lower and thereby heat the fork tubes less. It is thus possible to provide a hydraulic brake even with front fork made of aluminum or carbon. With one-sided hydraulic brakes this would not be possible because the material strength of aluminum or carbon significantly reduced at temperatures above 150 ° Celsius.
  • the racing brake as a hydraulic brake thus the advantage of disc brakes over rim brakes can also be used in racing bikes.
  • the brake discs are reduced in diameter, with a diameter of 120 to 140 mm, in particular about 125 mm is preferred
  • the two calipers are directly connected to the two fork tubes, and it is particularly preferred to arrange the brake calipers in the direction of travel behind the fork tubes.
  • This has the advantage that the forces acting on the attachment of the calipers forces are essentially compressive forces and not tensile forces.
  • the power transmission device is designed such that the braking force generated by the actuating device is transmitted uniformly to both brake discs. This can be ensured, for example, by guiding two separate Bowden cables to the brake cylinders from the direction of actuation, the tensile forces transmitted through the Bowden cable being converted into pressure forces acting on the brake disk by the hydraulic cylinder with a corresponding conversion device.
  • the Conversion device may be provided at a suitable location between the brake cylinders and the actuator.
  • the power transmission device has a force distributor.
  • the power distributor is connected to two hydraulic lines, each hydraulic line being connected to one of the two brake cylinders. This ensures that the same forces are transmitted to the brake discs of the two brake cylinders and thus a straight-ahead running of the wheel is ensured during braking.
  • a single power transmission device such as a Bowden cable provided.
  • this Kraftubertragungs Nevity, Inc., Inc., ausschS sekunde hydraulic lines for power transmission become.
  • the provision according to the invention of a hydraulic brake in racing bicycles also has the advantage that carbon rims can be used.
  • the provision of carbon rims is only possible to a limited extent because the rim brakes cause strong abrasion on the carbon rims. This can lead to a material weakening of the carbon rims, which is unacceptable especially at the high loads that act on racing wheels.
  • the provision of rim brakes in carbon rims is possible only with special brake pads. Particularly problematic is the carbon wheels carrying the force between the rims and the spokes,
  • the provision of two disc brakes according to the invention is advantageous in this case, since a uniform force transmission takes place. Since carbon wheels in conjunction with the hydraulic brake according to the invention meet the high requirements in this area, this also has the advantage that each rim 100 - 200 grams can be saved compared to a conventional fig.
  • the invention relates to a braking device for road bike brakes, wherein the braking device is particularly suitable for the road bike brake described above.
  • the braking device In hydraulic brakes for road bikes there is the problem that the Geberzyiinder, by the hydraulic pressure is built up, can not be provided in the brake lever on the racing handlebar. This is due to the fact that the racing handlebar is seized differently in different driving positions by the cyclist and therefore there is no space for mounting the master cylinder on the handlebar itself in the area of the brake lever.
  • a fork is here for weight reasons and because of their longer design (change the driving behavior - slower steering behavior, extension of the wheelbase) not used.
  • cyclists have to drive more often in teetering, for example, to counter the breakaway attempt of a counterparty or to be able to cope with shorter climbs without changing gear.
  • a suspension fork would thereby einfedem and a part of the leg strength thereby lost and not get into the drive.
  • the double disc brake therefore refers to a unsprung, so rigid fork in road bike, in order to ensure sufficient safe road contact with this fork, it must be designed elastic in the lower area. Otherwise, the front wheel was off in a wavy road for a short time, which could lead to a fall, for example, in a curve.
  • the disc brake is now fixed but exactly in this area on the fork.
  • the distortion caused by a one-sided disc brake would therefore be particularly noticeable.
  • a fork used in the racing bike area would not be designed reliable for the prevailing braking torque, it would lead to plastic deformation or even brewing.
