Embodiment Construction

[0039] Hereinafter, while referring to the accompanying drawings Figure 1 to Figure 11 Embodiments of the present invention will be described.

[0040] The accelerator pedal device of the present embodiment includes a cover 10 fixed to a vehicle body such as an automobile, a pedal arm 20 , a slider 30 , an urging spring 40 , a return spring 50 , and a position sensor 60 that detects the rotational angle position of the pedal arm 20 . .

[0041] The position sensor 60 is composed of an armature 61 , a permanent magnet 62 , a stator 63 , and a Hall element 64 .

[0042] Furthermore, a hysteresis generating mechanism for generating a hysteresis of the depression force of the accelerator pedal 24 is constituted by the contact portion 25 , which is a part of the pedal arm 20 , the slider 30 , and the biasing spring 40 .

[0043] The cover 10 is formed of a resin material, and is composed of a first cover 11 and a second cover 12 that are connected to each other and define the ax...

Abstract

This accelerator pedal device includes a pedal arm (20) having an accelerator pedal (24), a housing (10) that supports the pedal arm so as to be capable of swinging about a prescribed axis line (S) between a rest position and a maximum push position, a slider (30) that slides over an inner wall (11d) of the housing, a contact part (25) formed on the pedal arm in order to exert pressing force whileseparably coming into contact with the slider, and an urging spring (40) disposed between the housing and the slider so that the urging force pressing the slider against the inner wall (11d) and thecontact part (25) increases in accordance with the pushing of the accelerator pedal. This makes it possible to yield the desired hysteresis in the pushing force while achieving size reduction, etc.

Description

technical field [0001] The present invention relates to an accelerator pedal device suitable for use in a vehicle or the like using an electronic throttle control system, and more particularly, to an accelerator pedal device including a mechanism for generating hysteresis in the depression force of the accelerator pedal. Background technique [0002] As an accelerator pedal device mounted on an engine of an automobile or the like, as an accelerator pedal device suitable for an electronic throttle valve control system (also referred to as a throttle-by-wire system), an accelerator pedal having the following components and the like is known. Device: a pedal arm having an accelerator pedal; a housing for swingably supporting the pedal arm; a first return spring for returning the pedal arm to a rest position and disposed in the vicinity of the rocking support shaft; and a hysteresis generating mechanism for A hysteresis occurs in the depression force of the accelerator pedal (fo...
