DEVICE FOR MEASUREMENT OF TRACTIVE FORCE

摘要

Device for measurement of tractive force includes unit for receiving and transfer of force from source of load. The unit includes springy deformed part on parallel surfaces of which tensoresistors are placed. In elastically deformed part through slot is provided, surfaces of that one are placed at both sides of long axis of the part and are parallel to each other. Unit for receiving and transfer of force has rod that receives force from source of load, and additional link for its transfer. The rod and the additional link are in sequence connected to each other by means of joint to which hinge is included, as spherical bearing. Elastically deformed part has central part included to the bearing, within long section of that one through slot is placed, this is arranged asymmetrically with respect to long axis of cylindrical part of elastically deformed part. In the slot at parallel surfaces of its walls tensoresistors are fixed. At the outer surface of cylindrical section of the part round the slot two circular reborings are provided. Cylindrical section of the part can be arranged as bolt by means of which the rod is connected to additional link. At that in the body of the bolt long opening can be additionally provided, through that one from the through slot conductors from each of tensoresistors go out.
