Description
Technical field
The present invention relates to a kind of brake apparatus, especially a kind of brake clamp unit that can identify lever deformation belongs to
Motor vehicle braking system technical field.
Background technique
Brake clamp unit is one of key position of braking system, plays vital work to vehicle safety operation
With.As shown in Figure 1, brake clamp unit generally comprises the portions such as 1 ' of checking cylinder, 5 ' of 2 ' of brake clamp, 3 ' of brake pad and brake disc
Part, 2 ' of brake clamp further include the components such as hanger, brake plate support in addition to including 4 ' of external lever with enlarging function, external
The enlargement ratio of 4 ' of lever is 2, since the disc of brake clamp monotechnics condition predetermined brake nipper units alleviates gap pair
Side is 3~6mm, and the theoretic alleviation gap two-sided design of disc is 4.5mm.When vehicle braking, compression is filled with to 1 ' of checking cylinder
Air, compressed air pushes the piston in 1 ' of checking cylinder to open, to drive one end of 4 ' of external lever to move outward, close to system
The other end of dynamic 3 ' of brake lining moves inwardly, finally pushes 3 ' of brake pad close to the disk of 5 ' of brake disc, implements braking.?
Continue during vehicle braking with braking time, 5 ' of brake disc and 3 ' of brake pad have different degrees of abrasion respectively.
Therefore, in order to which the alleviation gap holding for guaranteeing 5 ' of brake disc and 3 ' of brake pad under brake clamp unit relieved state is relatively solid
It is fixed, it needs to be internally integrated brake lining clearance automatic-adjusting device (abbreviation lock tune device) in 1 ' of checking cylinder.Current lock tune device is adopted mostly
With two multi-thread non-self-locking nuts come adjust automatically brake lining gap, due to two nut arrangements differences, there are two types of main for lock tune utensil
The structure type wanted, but two kinds of structure types functionally have the same effect, and can guarantee that alleviating gap fixes.
1 ' of checking cylinder is most important one component, and structure is as shown in Fig. 2, mainly include 108 ' of housing assembly, guidance
Screw arbor assembly, 107 ' of clearance adjusting nut component, 109 ' of piston component and adjust five part 105 ' of shaft assembly, wherein cylinder body
108 ' of component and 101 ' of cylinder cap is cooperatively connected, and screw component includes screw rod, 102 ' of square key, 103 ' of guiding nut, guidance
106 ' of 104 ' of spring and tapered sleeve.Compressed gas is filled with into cylinder body, compressed gas pushes 109 ' of piston component to move right, into
And 103 ' of guiding nut pushes adjustment axis to move right, and when alleviating gap bilateral is 4.5mm, clearance adjusting nut component
107 ' do not occur to adjust gap effect, but as adjustment axis moves right together, until after 102 ' of square key movement E distance with cylinder
101 ' of lid contact, stop motion.At this point, 5 ' of brake disc has been bonded with 3 ' of brake pad, braking is come into effect.With brake disc
The abrasion of 5 ' and 3 ' of brake pad, after alleviating gap beyond 5.2mm (i.e. 28/40+4.5=5.2), 102 ' of square key is attached to cylinder cap
On 101 ', adjustment axis continues to move right at this time, and lock tune device starts to automatically adjust gap 0.7mm (i.e. 28/40=0.7), to protect
Card alleviation gap is fixed.
During vehicle braking, the part gap of 4 ' of external lever and 1 ' of checking cylinder, between pin shaft and the part of brake plate support
It is slow that gap, the alleviation gap of 5 ' of brake disc and 3 ' of brake pad, 4 ' of external lever and brake plate support elastic deformation are regarded as disc
Gap is solved, and carries out the foundation of gap adjustment as lock tune device.It is reported that brake plate support bushing, screw rod bushing, key-bolt is accumulative
Overproof bilateral gap is 2 × (0.33+0.63+0.1)=2.12mm, and 4 ' theory elastic deformation of external lever is 3mm, above accumulative
Overproof gap is 2.12+3=5.12mm.It therefore, is 4.5mm, then lock tune device if you need to guarantee that disc alleviates critical gap theory design value
It is 5.12+4.5=9.62mm that Theoretical Design, which acts E value, and value 9.7mm just can satisfy requirement.Therefore, when the above various gaps
And elastic deformation, when being more than 9.7mm, lock tune device will start to act, and adjust automatically screw rod advance 0.7mm, this makes it possible to guarantee disk
Piece alleviation gap is fixed.
It is analyzed according to the structural principle of the above brake clamp unit, after brake clamp clamps 5 ' of brake disc, by multiple
Braking and alleviate, due to lock tune device adjustment alleviate gap should be kept fixed it is constant.However, applicant sends out by test of many times
Existing, actually alleviation gap is not fixed and invariable, but is constantly reduced after repeatedly braking, alleviating, between finally alleviating
Gap is reduced to 3mm hereinafter, the requirement of 3~6mm as defined in having exceeded, causes alleviation gap not meet requirement, in this process
Although middle lock tune device has also carried out gap adjustment, various gaps and elastic deformation have been well beyond 9.7mm, have finally led
It causes to break down.
The reason of occurring for failure is analyzed, and mainly there are two reasons for discovery:
(1) elastic deformation of 4 ' of external lever is excessive, since the space of brake clamp unit, weight and brake force etc. are wanted
It asks, causes the design of 4 ' of external lever generally more elongated, elastic deformation of 4 ' of external lever in braking process is relatively difficult to
Control, the deformation of 4 ' of external lever is more than 3mm in braking process, this results in various gaps and elastic deformation total value is more than
9.7mm is led so that lock tune device adjusts when not needing adjustment since the elastic deformation of 4 ' of external lever gradually starts gap
The alleviation gap of disc is caused constantly to reduce；It, can be empty in lever material, technique, structure if increasing the rigidity of external lever merely
Between and weight on product design requirement is not achieved.
(2) adjustment of lock tune device gap is out of turn, and correct gap adjustment opportunity is 5 ' of brake disc and 3 ' of brake pad
Abrasion exceed specified value when, at this time disc alleviate gap increase, lead to the clearance adjusting nut and adjusting nut in lock tune device
Set separation, clearance adjusting nut can rotate on screw rod, and since lock tune device is one-way clutch, when 1 ' of checking cylinder is alleviated
Clearance adjusting nut cannot reversely rotate accordingly, and such adjusting nut, which just plays the role of reducing, alleviates gap.However it makes
For dynamic nipper units in braking process, total value caused by lock tune device becomes larger due to cannot recognize that 4 ' elastic deformation of external lever is super
9.7mm (disc alleviates gap and do not change at this time) is crossed, is adjusted in the gap that the opportunity of mistake triggers lock tune device, system
After the completion of dynamic clamp is alleviated, the alleviation gap of disc will be gradually reduced.
In summary, existing defects in structure design of the gap adjustment function inside 1 ' of checking cylinder at present, cause outside
In the case that lever 4 ' elastic deformation in portion's increases, lock tune device, which cannot recognize that, to be come, to trigger not right gap adjustment.Separately
Outside, checking cylinder is compact-sized due to small in size, is generally not provided with enlarging function, but passes through the external thick stick of brake clamp unit
Bar amplifies brake force, that is to say, that brake rigging generally only has level-one enlarging function.
