Embodiment 1

[0147] A method for arranging three pedals of a light truck, the method of arranging the three pedals is based on the following conditions: the method for arranging the three pedals of the light truck is the design of a suspended three-pedal; the seat height H30 and the span of the vehicle to be designed are known. H. Heel point AHP, the shape and size of the suspended accelerator pedal, the shape and size of the suspended brake pedal, the shape and size of the suspended clutch pedal, and the carpet plane in the compressed state, including the following steps:

[0148] Step 1. Preliminarily calculate the estimated pedal height h of the accelerator pedal according to H30:

[0149] h=-0.0005(H30) 2 +0.2025(H30)+138 Formula (1);

[0150] The pedal height h of the accelerator pedal can take a value within the range of the calculation result ± 10mm;

[0151] Step 2. Preliminarily calculate the estimated pedal angle Ra of the accelerator pedal according to H30:

[0152] Ra=0.0008...

Embodiment 2

[0188] Embodiment 2 is basically the same as Embodiment 1, and its difference is:

[0189] The three-pedal arrangement method of the light truck also includes comprehensively determining the lateral distribution of the accelerator pedal, brake pedal, and clutch pedal:

[0190] After arranging the lateral positions of the accelerator pedal, brake pedal and clutch pedal in step 8, determine whether the lateral positions of the accelerator pedal, brake pedal and clutch pedal meet the following judgment requirements at the same time,

[0191] The lateral span d of the center point C of the clutch pedal is 330 mm to 390 mm;

[0192] The lateral distance e between the brake pedal center point B and point H is 150 mm to 180 mm;

[0193] If the lateral positions of the accelerator pedal, brake pedal, and clutch pedal do not meet the determination requirements, then return to step 8 to adjust the lateral positions of the accelerator pedal, brake pedal, and clutch pedal;

[0194] If t...

Embodiment 3

[0196] Embodiment 3 is basically the same as Embodiment 2, and its difference is:

[0197] The three-pedal arrangement method of the light truck also includes checking the lateral distribution of the accelerator pedal and the brake pedal and the spatial relationship of the drop distribution:

[0198] After comprehensively determining the lateral distribution of the accelerator pedal, brake pedal and clutch pedal, check the lateral distribution of the accelerator pedal and the brake pedal and the spatial relationship of the normal drop according to the following requirements:

[0199] When 65≤b≤80, 35≤PL3≤-1.67b+173;

[0200] When 50≤b≤65, -0.5b+70≤PL3≤65;

[0201] If the arrangement of the accelerator pedal and brake pedal does not meet the above check requirements, return to step 1 to re-arrange;

[0202] If the arrangement of the accelerator pedal and the brake pedal meets the above verification requirements, proceed to step 9 for verification.

Abstract

A method for arranging three pedals of a light truck, comprising the following steps: preliminary calculation of the estimated pedal height h of the accelerator pedal according to H30; preliminary calculation of the estimated pedal angle Ra of the accelerator pedal according to H30; calculation of the accelerator pedal according to the seat height H30 of the vehicle to be designed Pedal plane angle A47; determine the initial position of the accelerator pedal according to the estimated pedal height h of the accelerator pedal, the estimated pedal angle Ra of the accelerator pedal, the plane angle A47 of the accelerator pedal, and the shape and size of the accelerator pedal; determine the stroke of the accelerator pedal; determine the accelerator pedal Center of rotation; arrange the normal height difference of the accelerator pedal, brake pedal, and clutch pedal; arrange the lateral positions of the accelerator pedal, brake pedal, and clutch pedal; check whether there is interference between the 3D data of the pedal and the surrounding parts. This design can effectively reduce the number of late design changes and trial prototypes, thereby improving layout efficiency, shortening the development cycle, and reducing development costs.

Description

technical field [0001] The invention relates to a method for arranging three pedals, in particular to a method for arranging three pedals of a light truck, and is particularly suitable for arranging the three pedals of a light truck. Background technique [0002] With the development of automobile industry technology, the three-pedal of light truck is an automobile part frequently operated by drivers, and its operation comfort and safety are particularly important. In the general layout design stage of the cab, it is necessary to arrange the three pedals and determine the basic parameters of the three pedals, including the starting angle of the pedals, the position of the central point of the pedals, etc. In the arrangement of three pedals, when determining the height and lateral position of the pedals, it is necessary to consider not only the comfort of the pedals, but also the relationship between the three pedals, especially to ensure smooth switching between the accelera...
