Embodiment Construction

[0011] first reference figure 1 , shows an embodiment of a pedal assembly 10 . In this embodiment, the pedal assembly 10 is an accelerator pedal assembly 10 .

[0012] Pedal assembly 10 includes an accelerator pedal 12 and a gear 20 connected by an arm 14 . The pedal assembly 10 also includes a rack 30 . The gear 20 and the rack 30 are housed in a housing 50 . In one embodiment, the gear 20, the rack 30 and the housing 50 are made of a resin material with relatively high wear resistance, such as POM (polyacetal, polyacetal), TEFLON TM ,etc.

[0013] Gear 20 includes a plurality of first teeth 24 . In one embodiment shown, a selected number of the first teeth 24 are located adjacent the rack 30 and the first teeth 24 are spaced apart from each other around a portion of the perimeter of the gear 20 . In the illustrated embodiment, the first teeth 24 are shaped as involute teeth. Therefore, the width of the first tooth 24 at the root end 25a is greater than the width of th...

Abstract

The inveniton discloses a pedal assemblythat includes a gear having a first tooth with a root and terminal ends. The gear rotates due to an input force. The assembly also includes a rack having a second tooth with root and terminal ends. The second tooth meshes with the first tooth at a contact point such that rotation of the gear causes linear movement of the rack. The assembly further includes a biasing member that biases the rack. The assembly additionally includes a slide member on which the rack slides. The slide member is provided on a side of the rack opposite to that of the gear such that the rack pushes on the slide member due to meshing of the first tooth and the second tooth.

Description

technical field [0001] The present invention relates to a pedal, more particularly to a pedal assembly for motor vehicles. Background technique [0002] There have been proposed pedal assemblies which electrically detect the amount of rotational displacement of the pedal by using a rotational angle sensor or the like. Depending on the detected displacement of the accelerator pedal from the rest position, the accelerator pedal assembly, for example, controls the throttle opening. US Patent No. 5,529,296 (Japanese Patent No. 3185498), US Patent No. 6,745,642 (International Patent Application No. 01 / 019638) and European Patent No. 0748713 also disclose such a pedal assembly. [0003] These pedal assemblies create a hysteresis characteristic between the rotational displacement of the pedal and the input force applied by the driver. More specifically, the moving part is pushed on the sliding part by an amount dependent on the pedal displacement. The pushing force of the moving...
