Description

Vehicle Cycle and reverse gear

The invention relates to a vehicle having the pedal drive and reverse gear according to the preamble of claim 1 and to a method for the eccentric muscle training with an inventive vehicle according to the preamble of claim 26th

Bicycles are usually powered by pedals, which are trampled with their feet. for the pedals are usually stepped forward for forward movement, resulting in optimal stress on the joints and muscles. In the downhill the pedals can rest and a freewheeling mechanism can free the wheels roll without the pedals rotate. When brakes are brake pads, drum brakes disc brakes or other energy-converting mechanisms via a hand lever or a cancellation mechanism used.

From US 7,445,223 HONG a bicycle drive with reversing gear is known, can be achieved by switching on and off of the reverse gear that the bicycle moves forward, when the pedals are driven in the forward or rearward facing direction of rotation. The reverse gear is arranged on Tretachsenlager. When forward rotation of the bottom bracket the torque exerted on the pedals is transmitted through a first one-way clutch to the sprocket, so that the rear wheel rotates forward, whereas when the reverse gear during reverse rotation of the pedal axis the torque exerted on the pedals on a second one-way clutch a planetary gear is transmitted to the sprocket, so that the rear wheel also rotates forward. As both one-way clutches transmit torque only on the bottom bracket on the rear sprocket and a torque is not transmitted from the rear wheel to the pedal axis in both cases by the two one-way clutches in bergabwärtsfahrendem bike no braking effect, by reverse rotation of the bottom bracket to the rear be exercised.

However, there are biomechanical sports aspects which an active braking of the drive through the muscles (so-called. "Eccentric training") can appear attractive. This is with bikes of today's state of the art but not in any meaningful way possible. The invention aims to remedy . the invention is based on the object to provide a vehicle with pedal drive and a reverse gear for eccentric training.

Eccentric muscle work is in many everyday activities and sports is of great importance, so when braking movements during landing, when skiing or downhill hiking. Even while jogging the proportion of eccentric muscle work is great. Each time a foot touches down, the muscle-tendon system is stretched like a spring elastic. During the immediately following Beinabstosses this elastic spring-energy contributes up to 50 percent for propulsive power. This property of the muscle itself make rennende or jumping animals advantage.

The invention achieves this object with a vehicle having the pedal drive and reverse gear, which has the features of claim 1 and a method for the eccentric muscle training with an inventive vehicle in accordance with claim 26th

The advantages achieved by the invention are to be seen essentially in the fact that due to the inventive device:

be stretched muscles against their opposition, loaded and trained in a different way than the concentric training -. Advantages of this reversal are within a factor of up to 5 decreased oxygen consumption for the same work at the same or even enhanced muscle building. The muscles and joints are loaded in the braking movement with the same force vectors as in the active forward movement of the bicycle, however, just in the opposite direction of movement of the muscles (ie, for example pedals and feet rotate braking backward during for example the bicycle forward downhill rolling). This has proven to be advantageous for the joint load because so reaches the optimum loading conditions for muscles and joints; and

- the musculoskeletal system (muscles, Looking, ligaments, bones and joints) is disproportionately burdened compared with the cycle. The energy consumption and the circuit load is significantly lower than a comparable concentric with eccentric load muscular work.

In the drive mode of the vehicle, ie when switched reversing mechanism, the bicycle in the conventional sense can be driven, while when the reversing mechanism, that is, in the braking mode at a caused by downhill driving or an electrical driving forward movement of the vehicle, a power transmission from the forward rotating rear wheel on the opposite, ie, backward rotating bottom bracket takes place, so that the vehicle can be braked by means of eccentric muscle strength. The goal is not the activation of a brake, but the transmission of the movement to pedals or eg movable lever whose active eccentric deceleration causes a deceleration driving. Since the reverse switched freewheeling clutch, the pedal crank and the second vehicle wheel are connected torsionally stiff in both directions of rotation, the vehicle can be driven when the reversing gear by reverse driving of the pedals in the forward direction. For example, it may be between comfortable when cycling, and backward running concentric to the pedals in order, for example, thrive on small slopes.

Further advantageous embodiments of the invention can be commented as follows:

In a specific embodiment of the vehicle, the one-way clutch in braking mode can be blocked or bypassed.

In another embodiment, the braking device comprises a brake lever, wherein on actuation of the brake lever, the one-way clutch can be switched from the brake mode to the driving mode. The advantage is achieved that if the brake mode during hill starts transmitted from the rear wheel on the pedals driving force is too large, the overrunning clutch can be switched to the drive mode by pressing the brake lever so that the overrunning clutch is in forward rotating rear idle. Due to this safety mechanism, the bicycle at an excessively high braking force is switched to an operation as in a conventional bicycle. In another embodiment of the vehicle, it comprises an automatic overload protection, by means of which the one-way clutch from the brake mode to the driving mode can be switched, preferably the reversing gear can be switched off. This embodiment enables that the overrunning clutch is switched to the drive mode in response to the overload protection device, for example a centrifugal force control and the driving force is not transmitted from the rear wheel to the pedals the advantage, and the bicycle can roll downhill without the pedals rotate.

In yet another embodiment of the vehicle, this comprises a clutch. Thus, a switch on the brake mode is enabled without impact forces when descending.

In another embodiment of the vehicle, the drive device or the reversing gear comprises a translation. The advantage is achieved that the driver can engage a particular gear before the hill starts and the eccentric training and so can adapt the pending Slope. Thus an approximately constant torque can be made with different inclination of the road, it needs changing gear ratios in the transmission of power from the pedal crank to the rear axle. This also applies to the transfer of the braking force in the opposite direction.

In another embodiment of the vehicle the reverse gear on the pedal crank is arranged.

In yet another embodiment of the vehicle, the reversing gearbox is integrated in the at least one second vehicle wheel.

Preferably, the reversing mechanism comprises a first shaft having a longitudinal axis, drive means, which comprise one or more chain wheels, belt wheels or elements of a shaft drive, and a second shaft, which is formed as concentrically arranged about the first shaft hollow shaft, the reversing gear between the first and , the second shaft is arranged so that when the reverse gear an opposite direction of rotation between the first and second wave is generated and switched reversing gear the same direction of rotation direction between the first and second wave is generated.

In a further embodiment of the vehicle, the first shaft is a hollow shaft and installed in the at least one second vehicle wheel. Thus, the advantage can be achieved that the first shaft can be mounted on the axle of a bicycle rear wheel. the entire reverse gear can be fixed to the rear fork of a Fahrradrahmes over such commercially available axle example with quick releases.

In a further embodiment, the vehicle comprises a measuring device for measuring the braking power in the braking mode, and preferably a microcomputer. The measuring device can be installed for example in the rear wheel hub of the vehicle. With a built-in computer and also a concurrent pulse measurement, the vehicle can be used for competitive sports and therapeutically or.

In still another embodiment, the vehicle comprises a switching device for switching on and off of the gearbox.

In another embodiment of the vehicle, the overrunning clutch by means of a second switching device from the driving mode into a braking mode can be switched.

In another embodiment, the vehicle comprises comprises an actuation device by means of which the first and the second switching device is actuatable.

In a further embodiment, the vehicle includes an electric drive, by means of which the vehicle is driven in forward direction.

In yet another embodiment of the vehicle, the electric drive comprises a programmable microcomputer, by means of which the driving force and / or the rotational speed of the electric drive is adjustable. So that the benefits can be achieved, for example, that load pattern for training purposes, for diagnosis or for therapy can be programmed. Further, it is possible that the more an exerciser in the braking mode is braking, that is, eccentrically trained, the quicker the bike is driven by the electric drive, whereby a motivating effect is attainable.

In a further embodiment, the vehicle comprises a force sensor, by means of which the driving force of the electric drive is adjustable. So that the drive power can be adapted to the needs of the user at a specific selected speed.

In another embodiment of the vehicle, the electric motor can also be operated as a generator. In a further embodiment of the vehicle an additional engine / generator group is arranged on the second vehicle wheel. The advantage is achievable that there are two mechanically separate functional groups. The first is connected to the bottom bracket and therefore in direct mechanical contact with the driver. The engine in the bottom bracket can be operated as a generator. Is also seated in the rear wheel hub motor / generator group. The connection between the two functional groups is an electric accumulator / battery. During braking, the motor drives (in the bottom bracket) the bicycle to and buys energy from the battery. In the drive mode, the motor acts as a generator and feeds the battery. Exactly the same is true of the functional group at the rear. Through the mechanical decoupling of the two functional groups of the system is very variable.

The inventive vehicle for the eccentric muscle training is preferably used.

Further preferred uses of the inventive vehicle are its use in diagnostic and / or therapeutic methods, particularly in rehabilitation training of heart patients. The advantage of the uses of the present invention, the vehicle is that the energy consumption and the circuit load in eccentric muscle work are significantly lower than a comparable concentric load. The musculoskeletal system (muscles, Looking, ligaments, bones and joints) is disproportionately burdened compared with the cycle. This property can take advantage of the rehabilitation training of heart patients, for example.

In a specific embodiment of the method of driving of the vehicle is in forward direction through downhill driving.
