Abstract
The utility model relates to an ADAM2 machinery auxiliary braking mechanism of a vacuum booster. The ADAM2 machinery auxiliary braking mechanism of the vacuum booster comprises a switching lining, a blocking platform, a touching part and a spring. The switching lining is placed on an inner ring of a control valve body of the vacuum booster and is normally located at a first position, wherein an axial clearance is formed between the first position and a control air valve assembly of the vacuum booster. An elastic arm is placed on the other side opposite to the switching lining, and a reverse hook is placed on the end portion of the elastic arm. The reverse hook is placed on the blocking platform in a hooking mode to limit the switching lining to the first position. The touching part is connected with an air valve body of the vacuum booster and is axially opposite to the elastic arm. When the air valve body moves towards a direction far away from the control air valve assembly to reach a triggering condition, the triggering part ejects the elastic arm outwards in the radial direction, and the reverse hook is disengaged from the blocking platform. The spring is placed on the switching lining in an abutting mode to exert axial force facing the control air valve assembly on the switching lining. When the reverse hook is disengaged from the blocking platform, the spring pushes the switching lining to a second position matched with the control air valve assembly.

Description of drawings
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated, wherein:
Fig. 1 illustrates a kind of existing vacuum booster sectional structure.
Fig. 2 illustrates the semi-sictional view structure according to the vacuum booster of the utility model one embodiment.
Fig. 3 illustrates the mode of operation of vacuum booster shown in Figure 2.
The specific embodiment
In order to contrast, Fig. 1 illustrates a kind of existing vacuum booster sectional structure.With reference to shown in Figure 1, vacuum booster can comprise cavity 10 simultaneously, and it further is divided into vacuum chamber 12 and air chamber 13 by epithelium supporting plate and epithelium 11.The by-pass valve control on vacuum servo gas right side comprises vacuum valve and air door.Vacuum valve is used to control vacuum chamber 12 and whether air chamber 13 is communicated with.Air door is used for control air and whether is allowed to enter air chamber 13.Under normal condition, vacuum valve is opened, and air door is closed, so vacuum chamber 12 and air chamber 13 communicate and be evacuated, and air can't enter vacuum chamber 12 and air chamber 13.When brake pedal was operated, vacuum valve was closed, and air door is checked card, and vacuum chamber 12 and air chamber 13 are by isolated, and air can enter air chamber 13.Like this, will have pressure reduction between vacuum chamber 12 and the air chamber 13, epithelium supporting plate and epithelium 11 will be promoted to vacuum chamber 12, thereby produce power-assisted.
The characteristics of the utility model embodiment are that vacuum valve and air door are improved, and a kind of ADAM2 type mechanical assistance stop mechanism is provided, and make vacuum booster can provide bigger power-assisted under the emergency state.Fig. 2 illustrates the semi-sictional view structure according to the vacuum booster of the utility model one embodiment.This sectional structure illustrates the valve part of vacuum servo gas.With reference to shown in Figure 2, vacuum valve comprises control valve body 21 and one control air valve assembly 22.Air door comprises air valve body 23, one control air valve assembly 22 and valve rod 24.That is to say the two shared one control air valve assembly 22.
In the present embodiment, control valve body 21 can form on the housing of whole valve.One control air valve assembly 22 is a cyclic structure, and itself and control valve body 21 cooperate, to close the valve port of vacuum valve.In one embodiment, one control air valve assembly 22 can be made of rubber.
For air door, air valve body 23 is arranged on the valve rod 24, and cooperates to close the valve port of air door with one control air valve assembly 22.Valve rod 24 can be pushed (among the figure for left) with treadle effort, and air valve body 23 is promoted left thereupon, thereby leaves one control air valve assembly 22, and the valve port 25(that opens air door is shown in Figure 3).Like this, air can pour in the air chamber of vacuum booster from the right side, forms power-assisted.But, the pouring in of air forms and can drive control valve body 21 behind the pressure reduction and one control air valve assembly 22 is moved to the left, and promptly moves to air valve body 26, thereby the trend of the valve port opening that reduces air door is arranged.This voluntary straining maneuver causes the valve port of air door to be difficult for being opened to required aperture at short notice, thereby causes required brake boost deficiency.
The mechanical assistance stop mechanism of present embodiment comprises switching lining 31, spring 32, retaining platform 33 and touch part 34.The inner ring that switching lining 31 is located at the control valve body 21 of vacuum booster also is in primary importance as shown in Figure 2 normally.In this primary importance, the side (being the right side among the figure) and 22 of the one control air valve assemblies of vacuum booster that switch lining 31 have an endplay G.Rely on one control air valve assembly 22 to realize with cooperating of control valve body 21 this moment aspect vacuum valve.The air door aspect relies on one control air valve assembly 22 to realize with cooperating of air valve body 23.
At the elastic arm 31a that has of the opposite opposite side that switches lining 31, the end of this elastic arm 31a has an overhead kick 31b.Overhead kick 31b colludes normally and is located at retaining platform 33, is limited in above-mentioned primary importance will switch lining 31.In the present embodiment, retaining platform 33 is to be integrally formed at control valve body 21.
When air valve body 23 when reaching a trigger condition away from the direction of one control air valve assembly 22 (among the figure for to the right) mobile, touch part 34 is outside this elastic arm of jack-up 31a radially, makes it crooked, thereby makes overhead kick 31b break away from retaining platform 33.
In a preferred embodiment, the mechanical assistance stop mechanism also can comprise a seal ring 34, is located to switch between lining 31 and this control valve body 21, plays sealing function.
In a preferred embodiment, the mechanical assistance stop mechanism also can comprise a backing pin 36, in order to move 22 during to the one control air valve assembly to the second place switching the leaving retaining platform 33 of lining 31, stop switching lining 31 to continue to move, and it is spacing in this second place to switch lining 31 to these one control air valve assembly 22 directions.
In a preferred embodiment, this touch part is to be integrally formed on this air valve body.
In a preferred embodiment, the major part of mechanical assistance stop mechanism switches lining 31 and can use plastic material to make.
In sum, the mechanical assistance stop mechanism that the utility model embodiment is proposed can make vacuum booster output reach maximum power-assisted point rapidly after triggering, for vehicle provides emergency braking.In addition, the trigger condition of mechanical assistance stop mechanism can be regulated according to customer demand.And this mechanical assistance stop mechanism uses the modularization standardized designs, can install this function additional based on existing traditional product.Further, the vital parts of mechanical assistance stop mechanism is a plastic material, reduces cost of product and weight.
Though the utility model is described with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, under the situation that does not break away from the utility model spirit, also can make the variation or the replacement of various equivalences, therefore, as long as in connotation scope of the present utility model in the scope to the variation of the foregoing description, claims that modification all will drop on the application.
