Abstract
The present invention pertains to a chassis part for connection and force transmission between a vehicle chassis of at least one wheel, consisting of fiber-reinforced plastics or plastic composite systems, preferably for a passenger car or utility vehicle. The present invention is characterized in that at least one means for measuring forces acting on the chassis parts is integrated in the plastic portions of the chassis parts.
Claims15
A chassis part for connection and force transmission between a vehicle chassis and at least one wheel of a motor vehicle, the chassis part comprising:
- a plastic portion consisting essentially of fiber-reinforced plastics or plastic composite systems defining a control arm;
- at least one measuring means for measuring forces acting on the chassis part, said measuring means being integrated in the plastic portion of the chassis part;
- an electronic documentation device wherein said measuring means is coupled with said electronic documentation device for receiving the measured forces;
- and
- a temperature sensor wherein coupling said measuring device with said electronic documentation device for the measured forces includes evaluating the measured values in the electronic documentation device based on the temperature sensed by the temperature sensor, further wherein the control arm consists of fiber-reinforced plastics or plastic composite systems.
A vehicle with a chassis part, the vehicle comprising:
- a chassis part control arm with a plastic portion consisting essentially of fiber-reinforced plastics or plastic composite systems and at least one measuring means for measuring forces acting on the chassis part, said measuring means being integrated in the plastic portion of the chassis part;
- and
- an electronic control device for stabilizing the driving and/or the position of the vehicle by action on driving or braking elements, said electronic control device being coupled to said measuring means;
- an electronic documentation device wherein said measuring means is coupled with said electronic documentation device for the measured forces;
- and
- a temperature sensor wherein coupling said measuring means with said electronic documentation device for the measured forces includes evaluating the measured values in the electronic documentation device based on the temperature sensed by the temperature sensor.
A method of using a chassis part, the method comprising:
- providing the chassis part as a control arm part made of plastic or composite materials with an integrated measuring device for measuring forces acting on the chassis part;
- measuring forces acting on the control arm part using the integrated measuring device
- providing a temperature sensor for temperature measurement in the region of the control arm;
- providing an electronic documentation device;
- coupling the measuring device with the electronic documentation device for the measured forces;
- and
- evaluating the measured values in the electronic documentation device based on the temperature sensed by the temperature sensor.
