Patent ID: 6874376

Claim:
A device for measuring an axle load of a motor vehicle, comprising at least one sensor having an extension-sensitive resistor ( 1 ), a first conductor track ( 2 ), and a second conductor track ( 3 ) with said resistor connecting between said first conductor track ( 2 ) and said second conductor track ( 3 ); wherein said at least one sensor is arranged on at least one component ( 12 ) of a motor vehicle, which component is subject to a change in shape as a function of the axle load, and with at least one insulating layer ( 4 , 5 ) being arranged in between the extension-sensitive resistor of said at least one sensor and the component of the vehicle, wherein there is at least one further conductor track ( 7 , 7 ′) located between the at least one insulating layer ( 4 , 5 ) and the component of the vehicle, the at least one sensor having an electrical output indicative of stress in said component produced by said change in shape in response to a loading of the vehicle axle; and wherein there is an electrically conductive leadthrough across said at least one insulating layer between the second conductor track and said at least one further conductor track ( 7 ).
