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 two members relatively pivotable about a connecting pin, and transmitting the operating force through the connecting pin; a load sensor, disposed in the pivotal movement connecting portion to receive a load in a predetermined linear direction for electrically detecting the operating force, regardless of variation of a 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, and the load sensor disposed such that one of the shaft member and the main body member is fixed to a sensor arranging member of one of the two members connected through the connecting pin in the pivotal movement connecting portion; a connecting pin guide disposed on the sensor arranging member, and defining a space in which the connecting pin is inserted, and the connecting pin guide linearly formed in a direction toward the axis of the shaft member, whereby the connecting pin is moved linearly within the space such that the connecting pin is linearly displaced with respect to the sensor arranging member in accordance with the depression of the operating pedal; and an interlocking member disposed between an other of the shaft member and the main body member of the load sensor and an other of the two members and connected relatively rotatably to the other of the two members through the connecting pin, to transmit the operating force or the reaction force from the connecting pin to the load sensor, the interlocking member moved linearly and displacing the other of the shaft member and the main body member of the load sensor in the predetermined linear direction in accordance with the linear movement of the connecting pin guided by the connecting pin guide.
