Abstract
The utility model discloses a brake pedal mechanism. According to the brake pedal mechanism, a first side board and a second side board of a pedal support are respectively provided with a first through hole and a second through hole which are different in the inner diameter. A rotary shaft body of a pedal rotary shaft only can penetrate through the first through hole with relatively larger inner diameter and forms a ladder end face with a threaded rod which is capable of penetrating through the second through hole with relatively smaller inner diameter. Therefore when the pedal rotary shaft is installed, a limit cap of the pedal rotary shaft abuts against the outer side of the first side board where the first through hole is located, the ladder end face formed by the rotary shaft body and the threaded rod is capable of abutting against the inner side of the second side board where the second through hole is located, and thus through abutting connection of the ladder end face on the inner side of the second side board, an interval between the first side board and the second side board can be located and supported in a reasonable range so that clamping stagnation and looseness of swing of a pedal arm are prevented from occurring when the brake pedal is trodden.
Description
Technical field
The utility model relates to the brake pedal technology of automobile, particularly a kind of brake treadle mechanism.
Background technology
Fig. 1 is the generalized section of a kind of brake treadle mechanism of the prior art.As shown in Figure 1, existing brake treadle mechanism comprises:
Pedal support 11, it has two side plate 11a and 11b that are oppositely arranged and the through hole 110b that is opened in the through hole 110a of side plate 11a and is opened in side plate 11b; Wherein, the internal diameter of two through hole 110a and 110b equates;
Pedal S. A. 12, limited cap 12b and thread rod 12c that it has rotating shaft body 12a and is connected to rotating shaft body 12a two ends; Wherein, the external diameter of rotating shaft body 12a and thread rod 12c is identical, and all less than or equal to the internal diameter of through hole 110a and 110b, the external diameter of limited cap 12b is greater than the internal diameter of through hole 110a and 110b; Rotating shaft body 12a between two side plate 11a and 11b and its two ends be located in respectively in through hole 110a and the 110b, and, rotating shaft body 12a is located in the outside that limited cap 12b that the end in the through hole 110a connects is connected to side plate 11a, and rotating shaft body 12a is located in thread rod 12c that the other end in the through hole 110b connects and stretches out the outside at side plate 11b;
Pedal sleeve 14, it is sheathed on the rotating shaft body 12a of pedal S. A. 12 between two side plate 11a and 11b;
Brake pedal (not indicating among Fig. 1), it is suspended at the below of pedal sleeve 14;
Pedal arm 15, it is connected between pedal sleeve 14 and the brake pedal.
Based on said structure, when the brake pedal of existing brake treadle mechanism was trampled, the movement of brake pedal can be with the swing of logical pedal arm 15, and orders about pedal sleeve 14 by the swing of pedal arm 15 and rotate around the rotating shaft body 12a of pedal S. A. 12.
Yet, in existing brake treadle mechanism, to the locking of pedal S. A. 12 by tightening jam nut 13 and realize and the locking degree being to control by the lashing force size to jam nut 13, therefore:
If jam nut 13 tighten tension, then the distance between the limited cap 12b of jam nut 13 and pedal S. A. 12 will be too small, thus, the be locked side plate 11a of nut 13 and limited cap 12b clamping and the interval between the 11b will reduce, and, because the internal diameter of rotating shaft body 12a is identical with thread rod 12c and less than or equal to through hole 110b, therefore, when interval between side plate 11a and the 11b occuring owing to being extruded when dwindling, rotating shaft body 12a can extend out to the outside of side plate 11b, and the trend that can't stop the interval between side plate 11a and the 11b to dwindle by support side plate 11b, thereby, interval between two side plate 11a and the 11b dwindles two end faces that will clamp pedal sleeve 14, and it is not smooth to cause pedal sleeve 14 to rotate, correspondingly, clamping stagnation just easily appears in the swing of pedal arm 15 when brake pedal is trampled;
If tightening of jam nut 13 is loose, then the distance between the limited cap 12b of jam nut 13 and pedal S. A. 12 will be excessive, thus, the be locked side plate 11a of nut 13 and limited cap 12b clamping and the interval between the 11b just might increase, thereby, interval between two side plate 11a and the 11b enlarges and will cause two side plate 11a and 11b not enough to the constrained force of pedal sleeve 14, and correspondingly, looseness just easily appears in the swing of pedal arm 15 when brake pedal is trampled.
This shows, existing brake treadle mechanism need to be controlled by the lashing force size locking degree of jam nut 13, but can't realize the location at pedal S. A. 12 axial directions, thereby affects the deceleration and stopping performance of brake treadle mechanism.

Namely, brake treadle mechanism in the present embodiment can be controlled by the lashing force size locking degree of jam nut 23, but also can on the axial direction of pedal S. A. 22, realize positioning control to the locking degree, thereby can guarantee the deceleration and stopping performance of brake treadle mechanism.
In addition, please again referring to Fig. 2:
In order to reduce the rigid collision of pedal sleeve 24 and the rotating shaft body 22a of pedal S. A. 22, the present embodiment can arrange the rotating shaft body 22a free-running fit of pedal sleeve 24 and pedal S. A. 22, and, brake treadle mechanism in the present embodiment may further include two cushion collar 26a and 26b, one of them cushion collar 26a is near the inboard of side plate 21a, and within pedal sleeve 24, being sheathed on the end that rotating shaft body 22a connects limited cap 22b, another cushion collar 26b is near the inboard of side plate 21b, and within pedal sleeve 24, be sheathed on the other end of rotating shaft body 22a connecting thread bar 22c;
In order to reduce the rigid collision of pedal sleeve 24 and two side plate 21a and 21b, the present embodiment can also arrange the axial length of pedal sleeve 24 less than the interval between two side plate 21a and the 21b, and, a cushion collar 26a near side plate 21a inboard can further have the flange 27a that is attached to side plate 21a inboard, similarly, another cushion collar 26b near side plate 21b can further have the flange that is attached to side plate 21b inboard.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the scope of the utility model protection.
