Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.Should be understood that embodiment described herein only is used for description and interpretation the utility model, is not limited to the utility model.
For the diaphragm brake chamber assembly, the pressure spring pretightening force size in the general and air chamber of braking response time length is closely related.It is big that the pressure spring pretightening force becomes, then corresponding prolongation of braking response time; The pressure spring pretightening force diminishes, then the corresponding shortening of braking response time.Therefore, make braking response time unanimity, just can fundamentally solve the vehicle inclined to one side problem of stopping as long as adjust the pressure spring pretightening force of left and right vehicle wheel both sides.
Figure 1 shows that diaphragm brake chamber assembly schematic cross-section according to a kind of mode of execution of the present utility model, this assembly comprises housing 1, be positioned at the diaphragm 2 of housing 1, the push rod 4 that drives and stretch out by the opening on the housing 1 by diaphragm 2, and the pressure spring 5 that is provided with and is used for bias voltage diaphragm 2 around push rod 4, wherein, the diaphragm brake chamber assembly also comprises adjusting nut 7 and adjustment sleeve 8, adjusting nut 7 is fixed in the opening of housing 1, adjustment sleeve 8 is screwed onto in the adjusting nut 7 and is compressed the bias voltage of spring 5, and push rod 4 can pass adjustment sleeve 8 with moving axially.Like this, can change the length of pressure spring 5 in the housing 1 by the mode that relative housing 1 screws in (or back-out) with the be spirally connected adjustment sleeve 8 of (promptly being threaded) of adjusting nut 7, thereby change the pretightening force of pressure spring 5.
When adjustment sleeve 8 relative housings 1 screwed in, adjustment sleeve 8 further compression pressure spring 5 made its shorten length, and the pretightening force of pressure spring 5 increases.Like this in when braking, for the length that makes push rod 4 elongations with adjust before compare and remain unchanged, must prolong the 2 expansion times of diaphragm, make push rod 4 obtain enough thrust and finish braking to overcome the pretightening force that increases on the pressure spring 5.In this way, the braking response time of air chamber can access corresponding change.
In order to make pressure spring 5 can keep stable when the length change, the utility model can also increase spring seat 6 between pressure spring 5 and adjustment sleeve 8.Wherein, an end of pressure spring 5 is resisted against the periphery of the opening of housing 1 by this spring seat 6.Because pressure spring 5 is exerted pressure on spring seat 6, an end of adjustment sleeve 8 is resisted against on the spring seat 6, and the other end of adjustment sleeve 8 then stretches out from the opening of housing 1.
Wherein, as shown in Figure 2, adjustment sleeve 8 stretch out from the opening of housing 1 the outer surface of the other end on notch 10 can be set.Like this, need not to use special tool, only rely on common tool such as screwdriver just can make adjustment sleeve 8 relative housings 1 screw in (or back-out), thereby finish adjusting quickly and easily the pressure spring pretightening force.
In addition, in order to increase the area of contact of push rod 4 and diaphragm 2, the diaphragm brake chamber assembly can also comprise push-plate 3 (also can be described as the diaphragm supporting disk).Wherein, an end of push rod 4 is connected to diaphragm 2 by push-plate 3, and the other end of pressure spring 5 is resisted against on the push-plate 3.Usually, an end of push rod 4 can be connected by soldering or the like on the push-plate 3.
Preferably, adjusting nut 7 is welded in the opening of housing 1.
In addition, occur rotating voluntarily relative to housing 1, can adopt the locking element locking adjustment sleeve 8 of various ways,, preferably use locking nut 9 as locking element according to mode of execution of the present utility model in order to prevent to adjust the adjustment sleeve 8 that finishes.During use, this locking nut 9 is screwed onto on the adjustment sleeve 8.
The problem that may occur according to vehicle is described mode of execution of the present utility model particularly below.
Stopping of vehicle partially generally can be divided into brake left avertence and two kinds of brake right avertence.When the brake left avertence appears in vehicle, generally be since vehicle left side air chamber to compare the right air chamber braking response time of vehicle shorter.Therefore, for making the braking response time unanimity of left and right sides air chamber, need suitably prolong the braking response time of left air chamber.
In this case, can be at first the locking nut 9 of left air chamber be unclamped, then screwdriver is inserted the notch 10 (Fig. 2) of adjustment sleeve 8 and locate, adjustment sleeve 8 is inwardly screwed in certain distance, lock locking nut 9 at last again.The braking response time of adjusted left air chamber is suitably prolonged, and the left and right sides air chamber braking response time realizes synchronously.
Equally, when brake right avertence appears in vehicle, generally be since the right air chamber of vehicle to compare the vehicle left side air chamber braking response time shorter.Therefore, for making the braking response time unanimity of left and right sides air chamber, need suitably prolong the braking response time of right air chamber, employed method is because identical with the method for adjusting left air chamber when the vehicle left avertence, so repeat no more.
It should be noted that the inclined to one side situation of stopping in the opposite direction can appear in brake back vehicle when the excessive situation of distance occurring screwing in regulating the process of adjustment sleeve 8.In order to correct this phenomenon, at this moment only the adjustment sleeve 8 relative housings 1 after regulating outwards need be screwed out (being inwardly to screw in during adjusting) suitable distance and get final product.
By technique scheme, the utility model can be adjusted the pretightening force size of pressure spring in the air chamber of left and right vehicle wheel both sides as required, makes the left and right vehicle wheel both sides realize synchronous braking, the generation of inclined to one side phenomenon thereby prevention and pre-anti-vehicle are stopped.Whole adjustment mode simple and fast has stronger applicability and operability.
Below describe preferred implementation of the present utility model in conjunction with the accompanying drawings in detail; but; the utility model is not limited to the detail in the above-mentioned mode of execution; in technical conceive scope of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
Need to prove in addition, each concrete technical characteristics described in above-mentioned embodiment under reconcilable situation, can make up by any suitable manner, for fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible compound modes.
In addition, also can carry out combination in any between the various mode of execution of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
