Definitions

  • the invention pertains to a method and a system in a vehicle. Specifically, the invention provides a mechanism for the regulation of load transfers in a vehicle comprising a bogie with at least one front axle and one rear axle.
  • BACKGROUND Vehicles with a bogie and/or tri-axle bogie are increasingly common in current vehicle fleets, partly because of accessibility and partly because of loading capacity. These vehicles are used in different applications and have different accessibility requirements and different requirements with respect to how they use load transfers.
  • Vehicle in this context means, for example, a truck, articulated truck, pick-up, van, camper, work truck, car, emergency vehicle, vessel, van, ATV, skidder, excavator, crane truck, tanker, motorcycle, wheel loader, moped, scooter, limousine, sports car, racing car, bumper car, truck bed, boat trailer, lawn mower, tank, snowmobile, snow cat, caravan, all-terrain vehicle, tractor, go-cart, bus, combine harvester, farm machinery or a similar manned or unmanned motorised vehicle, designed for land-based geographic transportation.
  • a bogie is a device which is usually located under the rear section below a carriage or vehicle with 2, 3, 4 , 5, etc. axles, with the objective of spreading the vehicle's load over several axles and thus reducing the axle pressure, increasing the loading capacity and also distributing the wheel pressure against the road, which, for example, entails less wear and tear of the roads and rips up less gravel when the vehicle is driven on a gravel road.
  • Trucks and similar vehicles are often built with a bogie, especially when they are used for heavy transports.
  • a bogie has at least two axles, which have a centre distance of less than two metres. In cases where a vehicle is built with three axles, and the distance between the first and third axles is not less than five metres, this is often termed a "tri-axle" instead of a bogie.
  • a truck bogie is usually not rotatable as it is in rail vehicles, which causes a certain tyre wear.
  • the wheels on one of the axles are sometimes rotatable, so that they swing outwards when the front wheels rotate, following the swing radius .
  • a tri-axle bogie is the term used for the special bogie axle with three axles. One or several wheels may be located on each axle end.
  • the wheel axles which are included in a bogie axle may either be driving, in which case they are termed driving axles, or simply rolling, in which case they are termed tag axles.
  • a bogie may be comprised of driving axles only, or a combination of at least one driving axle and one or several tag axles. If more than one axle is driving, the constructions are sometimes termed tandem or tridem.
  • a load transfer is carried out in a vehicle with a tri- axle bogie, see Fig. 1A, which has a tag axle and two driving axles according to prior art
  • the weight is first transferred from the tag axle to both driving axles, see Fig. IB.
  • the load is then transferred from one driving axle to the other driving axle, see Fig. 1C.
  • the reason for making such a load transfer may be to increase the pressure against the base in order to increase friction and thus achieve better traction.
  • One objective of this invention is therefore to be able to adapt and control load transfers in a vehicle with a bogie axle with two or more axles, in order to solve at least one of the problems specified above and thus to achieve an enhanced vehicle.
  • this objective is achieved by a method for the regulation of load transfers in a vehicle comprising a bogie with at least one front and one rear axle.
  • the method comprises a determination of the vehicle's driving conditions. Further, the method comprises the determination of a load transfer configuration for the vehicle, based on the vehicle's determined driving conditions, through regulation of a driver-controlled control for the selection of a load transfer configuration.
  • the method also comprises the generation of a control signal in a control device, which may be impacted by the driver-controlled control, in order to regulate the load transfer configuration according to the regulation made by the driver-controlled control. Further, the method also comprises sending of the generated control signal from the control device to a control mechanism for load transfer located in connection with the bogie.
  • the method comprises the adjustment of load transfers on the bogie via the control mechanism in accordance with the adjustment made by the driver-controlled control .
  • a system in a vehicle comprises a bogie with at least one front axle and one rear axle in order to adjust load transfers in the vehicle.
  • the system comprises a driver-controlled control for the selection of a load transfer configuration based on the vehicle's determined driving conditions.
  • the system comprises a control device which may be impacted by the driver-controlled control and adapted to generate and send a control signal.
  • the system comprises a control mechanism, adapted to receive the control signal and adjust the load transfer on the bogie in accordance with the adjustment made by the driver-controlled control.
  • a variable load transfer between driving axles may also make transports more efficient, having regard to other aspects such as time, wear and tear, and fuel consumption, according to some embodiments.

This invention may, however, be carried out in many different forms and should not be seen as limited to the embodiments described herein, which are instead intended to illuminate and illustrate different aspects of the invention.
  • FIG. 2 shows a vehicle 200 adapted for load transfers by a tri-axle bogie.
  • the vehicle 200 has a front wheel axle 210 and a rear bogie 220 consisting of a first driving axle 230- 1, a second driving axle 230-2 and a tag axle 230-3.
  • the vehicle 200 is arranged to travel forward in a driving direction 240.
  • the terms front and rear in this context refer to the vehicle's travelling direction 240.
  • the set of the bogie 220 on the vehicle 200 which is described above, i.e. a tri-axle bogie, is merely an example.
  • the vehicle 200 may, for example, be equipped with a number of front wheel axles 210.
  • the vehicle 200 may have a rear bogie 220 consisting of any number of axles 230-1, 230-2, 230-3 in some embodiments; such as two, three, four, five, six,..., ⁇ , etc.
  • the rear bogie axle may also comprise any combination of driving axles 230-1, 230-2 and tag axles 230-3 in different embodiments.
  • all axles 230-1, 230-2, 230-3 in the bogie 220 may consist of driving axles 230-1, 230-2 in certain embodiments.
  • the axles 230-1, 230-2, 230-3 in the bogie 220 may be suspended in suspension devices where at least some of these have a springy mounting with adjustable stiffness. Thus, the pressure may be distributed among the axles 230-1, 230-2, 230-3.
  • the springy mounting with adjustable stiffness may be pneumatically or hydraulically manoeuvrable, for example comprising air suspension including air supply and a control valve to regulate the air supply.
  • the vehicle 200 may sometimes want the load weight distributed over all the axles 230-1, 230-2, 230-3 in the bogie 220.
  • This will be illustrated later and discussed in connection with the description of Fig. 3A and Fig. 3B .
  • the vehicle's driver may, for example when driving on a slippery surface, prefer a load transfer from the front driving axle 230-1 to the rear driving axle 230-2, as illustrated and discussed in connection with the description of Fig. 4A and Fig. 4B.
  • Vehicles 200 driving on a slippery surface may in certain cases prefer to only unload the tag axle 230-3 and transfer this weight to the driving axles 230-1, 230-2 for reasons of accessibility.
  • the tag axle 230- 3 may either continue to roll on the road surface, but with reduced or zero load; alternatively, the tag axle 230-3 may be lifted up.
  • the swing radius is improved, but the stability in the vehicle 200 and its accessibility on a slippery surface is significantly worse than when the load transfer is made to the rear driving axle 230-2.
  • the tag axle 230-3 may either continue to roll on the road surface, but with reduced or zero load; alternatively the tag axle 230-3 may be lifted up.
  • the present invention also pertains to configurations where besides that the tag 230-3 may be lifted up, also that the bogie driving axle 230-1 may be lifted up.
  • This configuration configurations with liftable tag axle 230-3 and liftable driving axle 230-1 are obtained and that load transfers can be performed between the axles 230-1, 230-2 and 230-3. It results in more possibilities of combinations of the load transfer function in that the wheel base and wheel swing radius can be adapted to driving conditions. For an example if load transfers is performed from the front driving axle 230-1 to the rear driving axle 230-2 and the front driving axle 230-1 is lifted up, then the pressure on the rear driving axle 230-2 is increased and thereby longer wheelbase is gained and better stability on regular highway driving.
  • the vehicle 200 When the vehicle 200 has collected a load, e.g. milk in the event the vehicle 200 is a dairy truck, it may be advantageous to distribute the load over several axles, or even all the wheel axles 230-1, 230-2, 230-3 in the bogie 220.
  • a load e.g. milk in the event the vehicle 200 is a dairy truck
  • control 300 for example in the form of or comprising a handle 310 or a three-position switch, which gives the driver the ability to select among the various load transfers, in some embodiments, which is illustrated in figures 3B, 4B and 5B.
  • control 300 in the figures should only be viewed as an example of a design.
  • the control 5 300 may be equipped with a prompt for the different alternatives, such as "small swing radius required", “heavy load”, and/or "motorway”, or similar texts.
  • the control 300 may be designed as a switch, a number of pushbuttons, a slider, a software button or similar.
  • the driver is granted the ability to adjust the vehicle's load transfer to the driving situation, the road condition and the load, which leads to an enhanced vehicle 200, with improved driving behaviour, in particular in situations when a small swing radius is an advantage.
  • Figure 6 illustrates an example of an embodiment for the invention.
  • the flow diagram in figure 6 illustrates a method 600 for the regulation of load transfers in a vehicle 200, comprising a bogie 220 with at least one front axle 230-1 and one rear axle 230-2.
  • the bogie 220 may comprise at least
  • the bogie 220 may comprise a tri-axle bogie, a quadruple bogie, a quintuple bogie, a sextuple bogie, a septuple bogie, an octuple bogie and/or a nonuple bogie, etc. in different embodiments.
  • the method 600 may comprise a number of steps 601-605. However, it should be noted that certain parts of the steps described herein are only comprised in some alternative embodiments of the invention. Further, the steps
  • Step 601 The method 600 comprises the following steps : Step 601
  • the vehicle's driving condition is determined.
  • This determined driving condition which may be the existing or reguired condition, may comprise: reduced swing radius, improved control characteristics and traction, and/or load maximisation.
  • This driving condition may be confirmed or determined by the vehicle's driver.
  • the driver can, based on prevailing environmental conditions and/or vehicle related information, determine the said driving conditions.
  • Environmental conditions include that the driver takes into account such as current road condition, geographical position and/or weather conditions. But the driver also takes into account for vehicle related information such as the vehicle's load and/or the vehicle's driving behaviour. With the vehicle's driving behaviour it is for an example referred to if the vehicle tilts or if there is different braking grip on different wheels or instabilities in the steering wheel.
  • the determination is made in connection with driving the vehicle and based on vehicle related information.
  • the regulation of load transfers can be done based on current road condition, geographical position, weather condition but also based on information about the vehicle's driving behaviour and/or the vehicle's load. In certain driving situations it may be advantageous to distribute load over several axles, or even to all the wheel axles in the bogie, in order to maximise the size of the payload.
  • the driver is informed about the prevailing environmental conditions and/or vehicle related information via the communication module 740 and the driver can thus determine the vehicle's driving condition.
  • the communication module 740 is adapted to receive environmental signals from the control device 710 representing the prevailing environmental conditions but also vehicle related information such as information about vehicle load and information about the vehicle's driving behaviour.
  • Environmental signals (not shown in figure) represents e.g.
  • the control device 710 receives data from the vehicle's internal systems and sensors to generate environmental signals and vehicle related information.
  • Example of the vehicle's internal systems and sensors are tilt sensors, gyros, accelerometers, steering wheel angle sensors, yaw-rate sensors, temperature sensors, rain sensors, load sensing sensors, but also information from e.g. braking system and stability system can be used. Based on the information regarding the prevailing environmental conditions and vehicle related information the driver can determine the vehicle's driving conditions and thus the regulation of load transfer can be made.
