Vehicular operating pedal device with load sensor and operating device with load sensor

摘要

A clevis pin (connecting pin) (26) is inserted into a clearance hole (72), and is displaceable relative to an operating pedal (16). A pivotal moving link (68) is disposed between the clevis pin (26) and a sensor pin (64) of a load sensor (30). A reaction force applied from the clevis pin (26) to the load sensor (30) always acts in a substantially constant direction (substantially leftward in FIG. 1A) even if the operating pedal (16) and an operating rod (22) are pivoted relatively around the axis of the clevis pin (26) in accordance with the depressing operation of the operating pedal (16). Thus, the detecting accuracy of the load sensor (30) is heightened, and variation in detecting accuracy is prevented, rendering the high reliability.

1. A vehicular operating pedal device with a load sensor, comprising:
an operating pedal movably disposed on a pedal support fixed to a vehicle and depressed by a driver; a reaction force member to which an operating force of the operating pedal is transmitted and on which a reaction force corresponding to the operating force is acted; a pivotal movement connecting portion placed between the operating pedal and the reaction force member, connecting a pair of members about a connecting pin relatively pivotable, and transmitting the operating force through the connecting pin; a load sensor, disposed in a sensor housing hole with a predetermined clearance formed in a sensor arranging member in the pivotal movement connecting portion to receive a load in a predetermined direction for electrically detecting the operating force, regardless of variation of the direction of the reaction force relative to the operating pedal input from the reaction force member in accordance with a depression of the operating pedal, the load sensor including a shaft member, a main body member disposed to be relatively displaced to the shaft member in a direction perpendicular to an axis thereof, a deforming member spanned over the shaft member and the main body member, and strain detecting elements fixed to the deforming member and detecting a deformation caused in the deforming member by allowing relative displacement between the shaft member and the main body member in the direction perpendicular to the axis of the shaft member based on the reaction force; a pivotal moving link disposed on the sensor arranging member to be pivotable around a first supporting pin parallel to the connecting pin in the pivotal movement connecting portion, the pivotal moving link connected relatively pivotable to the connecting pin that is inserted into an elongated hole formed in the sensor arranging member to be displaceable relative to the sensor arranging member, and connected to one of the shaft member and the main body member of the load sensor to be pivoted around the first supporting pin by the operating force applied from the connecting pin or by the reaction force; and a swinging lever disposed on the sensor arranging member, connected to a second supporting pin parallel to the connecting pin to be swingable around the second supporting pin, and connected to the other of the shaft member and the main body.
