Definitions
- wheel vibrations In motor vehicle undercarriages, road grip can be reduced by wheel vibrations, and the latter and cardan shaft vibrations can significantly impair driving comfort. In the case of insufficiently balanced vehicles, resonance phenomena of the wheel vibrations occur primarily in the speed range between 80 and 120 km / h.
- finish balancer method in which the vehicle wheels are used, is also used for wheel systems that are made up of several individually balanced parts and for which the tolerances of the individual residual unbalances can result in impermissibly high system residual unbalances be rebalanced on one level when assembled. It makes sense with this method that balancing is carried out in the subcritical range and that the damping does not change during the balancing process, that is to say as a function of the speed. Balancing in the subcritical range is generally possible because all rotating system parts are pre-balanced during the manufacturing process. However, the requirement that the damping must not change with the wheel speed is not met, in particular with more modern chassis. Rather, such trolleys are designed so that the damping changes with the speed.
- This task is solved by creating a pre Direction for monitoring vibrations in motor vehicles during driving operation, in which selected system components rotating in relation to other chassis parts are monitored by means of at least one vibration sensor arranged on the bearing of the respective system component and the latter are operatively connected to a display device and / or a test adapter and in which A contactless speed and angle sensor as well as a circumferential marking are assigned to determine the position of unbalance for each monitored system component.
- the device makes it possible to check the balance states of the selected rotating system components during driving operation and to determine the size and position (circumferential angle) of the unbalance vectors that occur in the presence of unbalances, to display them and to carry out a comparison with standard values, specifically for each monitored system component separately.
- the standard values can be determined empirically using reference multi-mass systems in original motor vehicles with original components, and the standard values can be stored in electronic storage media.
- the selected rotating system components can be cardan shafts or other cardan shafts, but in particular the vehicle wheels.
- the necessary balancing weights according to mass and position to the system components which are subject to imbalance.
- DE-OS 29 05 931 discloses a device for monitoring shock absorbers and tire air pressure of vehicle wheels, in which an acceleration sensor is arranged on a supporting component of each vehicle wheel to be monitored and each acceleration sensor is followed by at least one evaluation circuit and the output signals of the evaluation circuit continuously with setpoints and / or compared with each other.
- DE-OS 35 41 494 Another device for tire pressure monitoring on vehicle wheels is known from DE-OS 35 41 494, in which a vibration meter is connected to parts which carry the respective vehicle wheel and vibrate with it during driving operation.
- DE-OS 35 41 901 also discloses a method - and a device used to carry out the method - for the automated monitoring of the steering and wheel suspension geometry as well as the state of balance of rotating parts connected to the steering linkage of the respective motor vehicle, with those occurring on the steering by means of an inductive sensor Torsional vibrations can be determined.
- an expedient embodiment provides that at least one vibration sensor is arranged on the wheel suspension of each vehicle wheel.
- vibrations in a direction essentially perpendicular to the roadway are generally easily absorbed by the spring and damping elements, but impair the road grip of the wheels, vibrations acting in parallel planes to the roadway lead to vibrations which are perceived as extremely unpleasant in the passenger compartment and lead to damage other system parts up to their breakage.
- at least one vibration sensor which is effective in a plane running approximately parallel to the roadway is arranged on the wheel suspension of each vehicle wheel.
- two vibration sensors effective in a plane approximately parallel to the roadway can be arranged on the wheel suspension of each vehicle wheel at a distance from one another, which then enable the balance of the vehicle wheels to be checked in two planes and thus the determination of dynamic imbalances.
- At least one vibration sensor which is effective approximately in the direction of movement of the associated shock absorber, is arranged on the wheel suspension of each vehicle wheel.
- the vibration states determined by means of these vibration sensors can also be displayed as absolute or relative deviations from the norm or can be queried via an on-board adapter. This makes it possible, for example, to continuously monitor the shock absorber functions using an electronic processor.
- At least one vibration sensor can also be arranged on the bearing of the cardan shaft (cardan shaft), which detects vibrations emanating from this functional element during driving and displays them.
- Vibration sensors or sensors of the type to be used in the device according to the invention are known. It can be a (hard) quartz vibration sensor or (soft) inductive vibration sensor.
- 1 shows a vehicle with horizontal vibration sensors arranged on the suspensions of all vehicle wheels in a side view
- 2 shows the undercarriage of the vehicle in a plan view with an outline indicated by dash-dotted lines
- Fig. 3 shows a vehicle wheel with indicated wheel suspension and spring damping in an enlarged side view compared to FIG. 1 and
- FIG. 4 shows the vehicle wheel in a view looking in the direction of arrow IV in FIG. 3.
- FIG. 1 and 2 schematically illustrate a car 10 with a chassis having four vehicle wheels 11 and a passenger compartment 12 accommodated on the latter.
- the front and rear vehicle wheels are each connected to one another by wheel axles 13 in a manner not of further interest here.
- wheel axles 13 can also be articulated axles.
- Each vehicle wheel 11 forms a multi-mass system and comprises, inter alia, a wheel hub 15 rotatably mounted on a wheel bearing 14, a rim 16 which is exchangeably fastened to the wheel hub with a tire 17 received thereon, and a disc brake, the brake disc 18 of which is firmly connected to the wheel hub, while the brake shoes and their actuating means are not shown in the drawing.
- Each wheel bearing 14 is fixed as a wheel suspension in the horizontal direction by means of links 20 which are articulated on the chassis of the vehicle, but are movable on the chassis in the vertical direction and is supported vertically on the chassis via a spring damping element 21.
- Each vehicle wheel 11 is a horizontal vibration assigned sensor 22, which can be a - hard quartz vibration sensor or a - soft - inductive vibration sensor.
- the vibration transducers are each arranged on a section 23 of the handlebars 20 that supports the mounting of the wheel bearings 14 on the chassis and surrounds the wheel bearing 14 in a U-shaped manner, specifically on the side of the wheel bearing concerned that is distant from the pivot point 19 of the respective link.
- a mark 24 is attached to the inner rim edge of each vehicle wheel and a contactless inductive sensor 25 aligned with the respective brand is assigned to each vehicle wheel as a speed and angle sensor.
- FIG. 4 shows two counterweights 26 clamped on the outer rim edge.
- the wheel systems are continuously monitored while the vehicle is in operation, and any imbalances that occur are immediately displayed as an absolute amount and position, or relatively as a deviation from the norm, as soon as they occur. It will thus determine the same measurement data during running operation as in the prior art when balancing dismantled vehicle wheels on stationary balancing machines, but according to the invention taking into account the vehicle-specific data.
- balancing weights can be attached to the rims of the vehicle wheels in a precise position. This usually happens on the outer rim edge. Balance weights can also be attached to the inner rim edge.
- the particular advantage of the invention is that not only the rims and the tires mounted on them are balanced, but all the parts of a wheel system that are rotating while driving and that can cause imbalances, namely under Consideration of the respective vehicle typical data.
- the invention can also be used for dynamic balancing if a further vibration sensor, for example in a measuring plane 31, is provided at an axial distance from the horizontal vibration sensor 22, which lies in a measuring plane 30.
- a dynamic balancing of such a wheel system can then be carried out by applying balancing weights on the outer and inner rim edges, which extend in balancing planes 30, 31.
