Bellows based system for measuring transport vehicle load, includes measuring device for degree of compression of bellows

摘要

#CMT# #/CMT# A means is provided for measuring the degree of compression for the bellows (20). This means comprises a device for measuring the surface area or height of the bellows. #CMT# : #/CMT# The weight of the load is transmitted to the vehicle axles (5-7) via air bellows connected to these axles. A device (8) is provided for determining the air pressure inside the bellows and a means is provided for converting the measured air pressure into a value corresponding to the load weight. #CMT#USE : #/CMT# For measuring the weight of a load on a transport vehicle such as a trailer, used to transport e.g. manure. #CMT#ADVANTAGE : #/CMT# Vehicle load can be measured more reliably since the measured degree of compression allows the bellows surface area to be determined with greater accuracy. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a transporter truck with a trailer which is fitted with the load measuring system. 3 : trailer 5-7 : wheel axles 8 : bellows air pressure sensors 9 : brake pressure sensor 13 : pressure sensor 20 : bellows.
