Problems solved by technology

When redesigning the spring, it often happens that the force value of a certain stroke meets the requirements after adjustment, but the part that does not need to be adjusted obviously before the adjustment also changes after the adjustment and does not meet the requirements. For example, although the maximum pedaling force drops, However, the initial pedaling force has increased beyond the design target value
[0004] 2. Even if the above situation can be accepted by the customer after adjustment, due to the redesign of the spring, the spring needs to be remade, the installation position needs to be changed, and the pedal bracket needs to be repaired. It will cost man-hours and cost
[0005] 3. After the spring is replaced, the durability test needs to be carried out again, which takes more than 40 days, and the design change period for the subject that needs urgent improvement is too long
[0006] 4. When the driver operates the vehicle, because the driver accepts different ranges of pedaling force and has different preferences for pedaling force, it is difficult to set a single force value range to cover all drivers' preferences, which may cause customers to be indifferent to the pedal force. Inappropriate complaints

Embodiment 1

[0067] see Figure 1-4 , is a schematic diagram of Embodiment 1 of the present invention.

[0068] The clutch pedal system with adjustable force value, including pedal bracket 1, pedal arm 2 and spring 3, one end of pedal arm 2 is the rotation center point A, the other end of pedal arm 2 is pedal point D, and pedal point D is provided with pedal 6. The stepping point D corresponds to the center of the pedal 6 . The rotation center point A and the pedal bracket 1 are rotatably connected, the bracket fixed side terminal 31 of the spring 3 is connected to the bracket side fixed axis C, the pedal arm fixed side terminal 32 of the spring 3 is connected to the pedal arm side fixed axis B, and the bracket side fixed axis C is installed on the pedal bracket 1, the pedal arm side fixed shaft B is installed in the middle section of the pedal arm 2, the pedal bracket 1 is provided with an adjustment groove 11, the bracket side fixed shaft C is defined in the adjustment groove 11, and th...

Embodiment 2

[0093] see Figure 5 As shown, it is a schematic structural diagram of the second embodiment.

[0094] The difference between the second embodiment and the first embodiment is that the fixed shaft C on the bracket side passes through the adjustment groove 11 and fits with the adjustment groove 11 in a clearance fit, and the fixed shaft C on the bracket side is connected with a transmission rod 4, which is connected with the self-locking motor 5, The self-locking motor 5 is mounted on the pedal bracket 1 .

[0095] The second embodiment uses the self-locking motor 5 and the transmission rod 4 to automatically adjust the fixed axis C on the side of the bracket, which does not require manual adjustment, and the adjustment result is more accurate. At the same time, there is no need for a locking nut. Through the control of the self-locking motor 5, the fixed shaft C on the bracket side can be positioned at any adjusted position.

[0096] In this embodiment, there are two transmi...

Embodiment 3

[0098] see Figure 6-8 As shown, it is a schematic diagram of the third embodiment.

[0099] The difference between the third embodiment and the first embodiment is: when sinA=0 and Fpad=0, it is the dead center position of the clutch pedal, that is, the position where the force value direction is reversed. At this time, the bracket side fixed axis C is along the adjustment groove 11 The adjustment trajectory of ∠A is any fixed value (including zero degrees), the adjustment groove 11 is a straight line along the AC line, the adjustment trajectory of the bracket side fixed axis C is a straight line along the AC, and the bracket side fixed axis C is in the adjustment slot 11. The adjustment trajectory is designed so that the dead center before and after pedal force adjustment remains unchanged. That is, when the fixed shaft C on the bracket side is located at any position in the adjustment groove 11, the dead center position of the pedal is the same during the movement.

Abstract

The invention discloses a clutch pedal system with an adjustable force value. The clutch pedal system comprises a pedal support, a pedal arm and a spring; one end of the pedal arm serves as a rotary center point, the other end of the pedal arm serves as a treading point, the rotary center point is rotatably connected with the pedal support, a support fixing side terminal of the spring is connectedwith a support side fixing shaft, a pedal arm fixing side terminal of the spring is connected with a pedal arm side fixing shaft, the support side fixing shaft is installed on the pedal support, thepedal arm side fixing shaft is installed in the middle section of the pedal arm, an adjusting groove is formed in the pedal support, and the support side fixing shaft can move in the adjusting grooveand is used for adjusting pedal force of the clutch pedal system. The invention further discloses an adjusting method of the force value of a clutch pedal. The clutch pedal system with the adjustableforce value and the adjusting method of the force value of the clutch pedal have the advantages that the design is facilitated, the adjusting scheme is flexible, the design time is short, and the costis low.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a clutch pedal system with adjustable force value and a method for adjusting the force value of the clutch pedal. Background technique [0002] Existing clutch pedals have the following problems: [0003] 1. The pedal force of the clutch pedal is often complained by customers that it is not suitable. In order to match the performance requirements of the clutch system, the spring of the pedal needs to be redesigned. When redesigning the spring, it often happens that the force value of a certain stroke is adjusted to meet the requirements, but the parts that do not need to be significantly adjusted before adjustment have also changed after adjustment and do not meet the requirements. For example, although the maximum pedaling force has decreased, However, the initial pedaling force has increased beyond the design target value. [0004] 2. Even if the above situation can be ac...
