Definitions

  • the invention relates to a vehicle combination of a towing vehicle and at least one semi-trailer, which are coupled to one another by means of a coupling device with two rotatably interlocking coupling parts, one of which coupling part is supported on the towing vehicle and the other coupling part on the semi-trailer.
  • Vehicle combinations with a semi-trailer have a braking device (trailer braking device), which automatically brakes the semi-trailer pneumatically or hydraulically with each braking.
  • a braking device tilted braking device
  • it is not permitted to brake a trailer with an overrun braking device and to actuate it using a conventional fifth wheel.
  • the object of the invention is to relieve the coupling part and its support on the towing vehicle when driving with a coupled semitrailer and to avoid dangerous driving conditions of the vehicle combination.
  • the semitrailer which is coupled to the towing vehicle by means of a coupling device with two rotatably interlocking coupling parts, is equipped with a new type of overrun brake device.
  • a two-armed deflection lever is provided, which is pivotally supported on a trailer frame of the semitrailer to a limited extent and on whose one lever arm the coupling part of the semitrailer interacting with the coupling part of the towing vehicle is supported.
  • the reversing movement of the reversing lever makes it possible, for example, to provide such an overrun braking device for the semi-trailer, the overrun braking device of which, like that of a conventional vehicle trailer pulled by means of a drawbar, is integrated in a known manner
  • Shock absorption and attached (not actuated) hand lever for the parking brake is built, from the pushing movement of which the actuation of a brake cable or an encoder for a hydraulic brake system is derived.
  • the bell crank can be installed between the front end of the towing vehicle and the overrun device of the overrun braking device, so that the overrun device for braking is stressed on train. So that the overrun device of the overrun braking device responds to thrust load, the overrun device can, however, be installed between the relevant lever arm of the bell crank and the front end of the trailer.
  • the overrun brake device according to the invention works very sensitively because of the very favorable lever ratios from the clutch device to the overrun device. In all driving conditions, in particular when cornering, the overrun braking device according to the invention is then significantly safer for a vehicle combination with a trailer than a braking device to be actuated by the driver.
  • overrun braking device works automatically and always prevents thrust even when the towing vehicle is at right angles to the semitrailer. Furthermore, this property is optimized by the sensitivity of this braking device which arises as a result of very favorable force efficiency.
  • the required limited pivoting movement of the deflection lever also with respect to the towing vehicle can be achieved by supporting the coupling part arranged on the towing vehicle on the towing vehicle with a correspondingly limited pivoting motion and / or by means of a correspondingly pivotable connection of the coupling part arranged on the deflection lever relative to the deflection lever.
  • the coupling part arranged on the deflection lever is preferably fixed on the relevant lever arm of the deflection lever and on the coupling part of the towing vehicle in accordance with the pivoting movability of the bell crank pivotally supported.
  • the coupling device is designed as a gimbal-movable, load-bearing joint, such as a conventional ball joint, the two coupling parts of which are designed as a ball socket or a two-part ball neck ring flanged thereon.
  • the towing vehicle is in particular a road motor vehicle with interchangeable rear bodies, each of which is locked via a load coupling in the form of a coupling device with two interlocking coupling parts to the load-bearing floor assembly of the motor vehicle, on which the wheels of the motor vehicle are also suspended.
  • the coupling part of this load coupling which is supported on the motor vehicle, is optionally also suitable for coupling the semitrailer.
  • Coupling part is thus designed and fixed to the floor assembly of the motor vehicle in the area of the rear axle of the towing vehicle in such a way that the semi-trailer loads of the semi-trailer as well as the pulling forces and pushing forces required for pulling the semi-trailer in all driving conditions into the
  • This concept largely accommodates this concept of locking the variable rear superstructures of a road motor vehicle to the motor vehicle via a central load coupling, which is optionally also suitable for coupling a semi-trailer. Since the tractive forces occurring in trailer operation can be better absorbed than pushing forces, the use of
  • the load coupling and its support structure on the floor assembly of the towing vehicle can be designed to be structurally lighter in accordance with the lower shear stress in trailer operation than in trailer operation without overrun brake.
  • FIG. 1 is a side view of a vehicle combination according to the invention
  • Fig. 2 is a side view of the coupling device between the towing vehicle and trailer and
  • Fig. 3 shows the coupling device from Fig. 2 in rear view.
  • a coupling device 3 designed as a ball coupling is arranged in the area in front of the rear axle 13 of the tractor vehicle, by means of which a semi-trailer 2 is coupled to the tractor vehicle 1.
  • the coupling device 3 has a coupling part 5, which is designed here as a ball socket and is supported on the load-bearing floor assembly comprising the base plate 12 and the main frame 14, and a coupling part 4, which is designed here as a ball head, which rotates into the coupling part 5 intervenes.
  • the coupling part 4 is fixed via a flange connection to the one lever arm 7 of a deflection lever 6 designed as a lever cross, which is about a swivel axis 15 in the form of
  • the pivot pin is supported on a semitrailer frame 9 of the semitrailer trailer 2 so that it can pivot to a limited extent.
  • the overrun device 10 of an overrun braking device is installed, with which the semi-trailer 2 is equipped.
  • a brake cable 11 is actuated to actuate the overrun brake device.
  • the brake cable 11 it is also possible for the brake cable 11 to be actuated not under a thrust load but rather under a tensile load.
  • the overrun device 10 is designed so that in Direction of travel is installed behind the other lever arm 8 and responds to tensile load instead of thrust load.
  • the force on the overrun device 10 can be selected by the ratio between the length of the one lever arm 7 and the length of the other lever arm 8.
