Title:
LONGITUDINAL FORCE DETECTING DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2714627
Kind Code:
B2
Abstract:
PURPOSE: To dispense with calibration, together with a connecting device, by demounting the connecting device from a vehicle, permit calibration without using a large-sized pulling and compression tester, permit manufacture at a low cost, and detect the longitudinal force acting on the connecting device in a stable manner with high precision.
CONSTITUTION: A buffer device 3 is fitted at the buffer device side fitting part 1a of a connecting pin 1, and the basic end of a connecting device 2 is fitted at the connecting device side fitting parts 1b and 1c. When each pulling force acts in the reverse direction between the connecting device 2 and the buffer device 3, the strain generating parts 1f and 1g which are formed by drilling the face throttle holes H1 and H2 from the reverse directions on the small diameter parts 1d and 1e are applied with each shearing force, and each shearing strain is generated. Since, as for each face of the strain generating parts 1f and 1g, the connecting pin 1 is fixed for the connecting device 2 so as to be parallel to the longitudinal direction of the connecting device 2, the pulling force and compression force which act in the longitudinal direction of the connecting device 2 can be always detected, even if the connecting device 2 changes direction.
