Definitions

  • the invention relates to a sports and recreational vehicle with at least three bendable wheels according to the preamble of claim 1.
  • a tricycle with two small front wheels is known in which with the steering movement and the curve inclination is controlled .
  • This vehicle is designed primarily as a synthetic, comparable to a unicycle, and tilts sideways in the state. Neither a relaxed sitting position, nor a safe driving style are possible.
  • WO 86/02897 describes a tricycle whose driver's seat and front fork are rigidly connected to one another. The steering is done here partly by shifting the body weight. However, the handlebar itself is attached to the vehicle frame, which is connected to the two rear wheels. The handlebar does not resonate with the steering movement, but is used to support the body weight. So that the vehicle does not tip over in the curve, the driver's seat is arranged very low. A use in the public traffic does not make sense because of the lack of overview.
  • the object of the invention is to design a manually or power driven three- or four-wheel vehicle with good traction, the curve inclination is controlled at slow speed mainly by the steering angle and fast travel predominantly by the displacement of the body weight of the driver.
  • the object of the invention is to practice the learning of body-displaced vehicle leaning step by step.
  • the core of the invention is therefore the idea that the wheel of the vehicle is connected in each case by a control rod with one of the two oppositely movable rear swingarms and the inclination of the vehicle coupled to the steering angle and that arranged between the steering head and the wheel carrier separable with a clutch control ring is, whereby the coupling of steering angle and vehicle inclination can be partially or completely canceled and that in the embodiment as a tricycle, the crankshaft in the front wheel is connected to the input of a switchable, multi-speed transmission and the front hub is connected to the output of this transmission.

  • the steering head (24) On the vehicle frame (1) of the steering head (24) as a bearing of the wheel carrier (3) and the mounting of the counter-movable rear swingarms (4a, b) and the driver's seat (22) are arranged.
  • the wheel carrier (3) which may be designed as a front fork (37), a rotatable control ring (16) which can be firmly connected via a coupling with the wheel carrier (3).
  • the movement of the steering angle via two on the control ring (16) located driver (36a, b) and two control rods (5a, b) on the opposite movable rear swing (4a, b) transmitted.
  • the right rear swing arm (4b) When turning to the right, the right rear swing arm (4b) is moved up and the left rear swing arm (4a) is moved down. So the inclination of the vehicle is initiated to the right side.
  • the wheel carrier (3) consists of a conventional front fork (37).
  • a pedal crank (23) integrated be.
  • the shaft (48) of the crank (23) is rotatably received at the lower end of the front fork (37) with the Vorderradgabellagern (38 a, b).
  • the front hub (49) with the hub bearings (39a, b) also rotatably mounted on the shaft (48) of the pedal crank (23). Since a front wheel without gearbox can be driven manually only with great effort and poor traction, the shaft (48) of the pedal crank (23) with the large drive wheel (40) of a chain drive should be firmly connected.
  • the large drive wheel (40) acts via the drive chain (41) on the small drive wheel (42) at the input of a multi-stage, switchable transmission (43).
  • the large output gear (44) at the output of the transmission (43) acts on the output chain (45) on the small output gear (46) which is fixedly connected to the front hub (49).
  • the central gear shaft (47) can be fixed and mounted at the upper end of the front fork (37). It thus lies outside the front wheel (26) and can be switched with conventional components available on the market.
  • the shaft (48) of the pedal crank (23) with the central gear shaft (47) would be identical.
  • the complete transmission (43) would rotate within the front hub (49) together with the shaft (48) of the crank (23).
  • the shift rod in the hollow bore of the shaft (48) of the crank (23) would have to be operated either with the feet or by infrared or radio.
  • the steering angle of the front fork (37) in manual front-wheel drive must be made relatively large in order to minimize negative steering influences by the driving torque of the pedal crank (23).
  • the four-wheel drive vehicle can also be driven manually via a crank drive (9) and a chain (10) and, if necessary, assisted by a drive motor (11), for example an electric motor or an internal combustion engine.
  • the crank mechanism works in this case, however, only one of the two rear wheels.
  • the centrifugal forces of the wheels (26) stabilize the ride.
  • the coupling of steering angle and tilting technology should be canceled by the clutch is disconnected.
  • the control ring (16) rotates freely on the bearing axis (19) of the steering head (24), whereby at the rear wheel swing (4a, b) only the opposite compensating movement is ensured.
  • the operation of the clutch which is integrated in the wheel carrier (3), can be done manually with a hand lever (18) with return spring.
  • the hand lever (18) When stationary or when driving slowly, the hand lever (18) is pulled, whereby the rotation of the control ring (16) is coupled to the steering angle of the wheel carrier (3).
  • the hand lever (18) When driving fast, the hand lever (18) is released.
  • the control ring (16) only loosely serves as a transmission member for the opposite movement of the rear wheel swing (4a, b).
  • a screw (37) can be used with the coupling of steering angle and inclination can be varied in general.
  • the coupling itself may be designed as a spring-loaded wedge (33), which presses on a flattened portion of the control ring (16).
  • the actuation of the clutch on the control ring (16) can also be done automatically.
  • a hydraulic pump (20) is flanged onto the output shaft (27) of the drive motor (11), which is connected via a hydraulic line to the clutch.
  • a hydraulic valve is actuated, which separates the clutch on the control ring (16). In this way, the steering angle is coupled to the wheel carrier (3) at low driving speed to the opposite movement of the rear wheel swing (4a, b) and is automatically released at higher speed.
  • the drivers (36a, b) on the control ring (16) can also act with hydraulic cylinders (20) and a hydraulic line (21a, b) instead of with a control rod (5a, b) on the counter-movable rear swinging wheels (4a, b). Since mainly tensile load occurs, the connection with chains is conceivable.
  • the return springs (8a, b, c, d) can also be designed as a plastic buffer.
  • the tricycle with two rear wheels and a front wheel is driven in the simplest variant with a direct crank (23) in the front wheel (26), resulting in the construction of a children's tricycle. Tilt and steering are coupled here. This makes it very easy to learn the angle when cornering for children.
  • the first driving exercises can be supported here by a flanged push and handlebar (14). Analogous to the growing driving skills of the children, the track width of the rear wheels can be reduced. Thus, the oblique position - similar to the corresponding four-wheel vehicles possible - increases when cornering, as shown in Fig. 8-10.
  • the clutch for separating the control ring (16) can be omitted in this type of learning vehicles because of the low speeds.
  • the footrest system (32) fixed to the wheel carrier (3), which is executed in a tricycle with two rear wheels as a front fork (37).
  • the footrest system (32) is integrated in the protective plate (31) of the front wheel (26).

Abstract

L'invention concerne un véhicule de sport et de loisirs comprenant au moins trois roues inclinables dans les virages. Le support de roue (3) de la roue avant, réalisable comme une fourche de roue avant, est relié dans la zone arrière à deux bras oscillants (4a, 4b) se déplaçant en sens inverse, par deux barres de commande (5a, 5b). L'inclinaison dans les virages du véhicule est couplée au braquage. Une bague de commande (16) pouvant être séparée d'un couplage est également placée entre la tête de direction (24) et le support de roue (3) et permet de supprimer à nouveau entièrement ou partiellement le couplage du braquage et l'inclinaison du véhicule. Dans la zone avant du véhicule, des bras oscillants se déplaçant en sens inverse permettent également de guider deux roues. Le dispositif de compensation s'appuie sur le cadre du véhicule.
