Description
Technical field
The utility model belongs to automotive brake field, more particularly to a kind of automobile brake clamp guide sleeve dust cover.
Background technology
Brake caliper has very important effect as the part in automobile inside brake assembly system, quality
Can quality directly affects automobile provide effective brake force after driver steps on brake in running at high speed to automobile,
Belong to crucial parts.Caliper brake brake caliper can slidably reciprocate in braking along guide sleeve.Guide sleeve dust cover is peace
A rubber parts between guide sleeve and brake caliper, is mainly used for preventing the pollutants such as dust, liquid from entering guide sleeve.
In the prior art, the automobile of China's production, is answered on the calliper of especially large and medium-sized passenger car
Guide sleeve dust cover, shortcoming mainly have：
1, used guide sleeve dust cover will produce internal vapour lock when brake caliper slides on calliper, very
To vacuum vapour lock is formed braking time and braking efficiency are influenced to increase working resistance；
2, the structure of lubrication oil, brake do not make inside used guide sleeve dust cover on calliper
Use short life.
Utility model content
The utility model be in order to solve the technical problems existing in the prior art, and it is open it is a kind of it is reasonable for structure, making
Moving calipers not will produce vapour lock, a kind of automobile brake clamp guide sleeve dust cover with lubricating action when sliding.
The utility model is to solve the technical problems existing in the prior art to take following technical scheme：
A kind of automobile brake clamp guide sleeve dust cover, it is characterised in that：It includes at least：
Telescopic dust boot body；
The fixing sleeve being connect with guide sleeve；
The sliding sleeve being connect with brake caliper；Wherein：
The fixing sleeve, dust boot body and sliding sleeve three are sequentially connected composition gas channel；In the sliding sleeve
Inner surface, the air channel for being equipped with several inventory of gas in an axial direction.
Further, the air channel quantity is 3.
Further, the air channel is U-lag.
Further, on the inner surface of fixing sleeve and the inner surface of sliding sleeve, several equally distributed profits are circumferentially provided with
Sliding slot.
Further, the lubrication groove quantity is 1-2.
Further, the cross section of the lubrication groove is rectangle.
The beneficial effects of the utility model and advantage are：
Dust cover described in the utility model is provided with several U-shaped air channels for reducing in an axial direction on the internal diameter of sliding sleeve
Vapour lock effectively increases the braking time and braking efficiency of caliper brake；Dust cover described in the utility model is in its fixing sleeve
It is used to store lubricant grease with lubrication groove is circumferentially provided on sliding sleeve inside diameter surface, contributes to the cunning of dust cover and brake caliper
It is dynamic, play the role of extending dust cover and brake caliper service life well.The utility model is especially suitable for large and medium-sized carrying vapour
The larger caliper brake assembly that vehicle uses；It is more suitable for the larger caliper brake assembly of four lifting lug of bilateral.
Description of the drawings
Attached drawing 1 is the front view of the utility model embodiment.
Attached drawing 2 is the E-E sectional views of Fig. 1.
Attached drawing 3 is the installation diagram of the utility model embodiment.
Attached drawing 4 is the partial enlarged view in the installation gap of Fig. 3.
It is marked in figure：1, dust boot body；2, fixing sleeve；3, sliding sleeve；4, guide sleeve；5, brake caliper；6, braking clamp
Clamp holder；7, air channel；8, gap is installed；9, lubrication groove.
Specific implementation mode
For that can further appreciate that the contents, features and effects of the utility model, the following examples are hereby given, and coordinates Fig. 1
To Fig. 4, detailed description are as follows：
A kind of automobile brake clamp guide sleeve dust cover of the utility model, includes at least：
Dust boot body 1；The fixing sleeve 2 being connect with guide sleeve；The sliding sleeve 3 being connect with brake caliper；Wherein：It is described
Fixing sleeve 2, dust boot body 1 and 3 three of sliding sleeve are sequentially connected composition gas channel；Inner surface, edge in the sliding sleeve 3
It is axially arranged with the air channel 9 of several inventory of gas.The dust boot body 1 is telescopic bellows, and dust cover is by oil resistant
Rubber is made.
Sliding sleeve 3 inner surface, be uniformly provided with the air channels 7 of several inventory of gas in an axial direction；Preferably, described logical
Air drain 7 is U-lag, and quantity is 3.The dust cover is pairs of at certain intervals to be assemblied on guide sleeve 4.When installation, braking
Clamp 5 are installed on guide sleeve 4 by brake caliper holder 6, and there are certain installation gaps between guide sleeve 4 and brake caliper 5
8, above-mentioned pairs of dust cover carries out gas exchanges by the installation gap 8, and formation one is relatively close inside two dust covers
Gas chamber sealing, ganging up, such design structure make brake caliper 5 when sliding work on guide sleeve 4, as shown in figure 3, anti-
Dust hood B is compressed, and dust cover A is stretched, at this time the gas inside compressed dust cover B by the installation gap 8 to drawing
The dust cover A flowings stretched；When brake caliper 5 slides round about, dust cover B is gradually stretched, the gas in dust cover A
As the sliding of brake caliper 5 flows to dust cover B.Therefore the sliding that internal vapour lock is brought is not present in the dust cover of the utility model
Resistance, effective braking time and braking efficiency for improving caliper brake.
Preferably, the installation gap is 0.1 millimeter；Or it is preferred, the installation gap is 0.15 millimeter.
Preferably, it for large and medium-sized passenger car, needs that a guide sleeve 4 is each side arranged in brake caliper 5, together
When the dust cover of pairs of the utility model is equipped on each guide sleeve 4.
For dust cover when being slid on guide sleeve 4, sliding requires resistance small and stable movement, non-jitter；In order to realize this
Effect, it is preferred that on the inner surface of fixing sleeve 2 and the inner surface of sliding sleeve 3, be circumferentially provided with several equally distributed profits
Sliding slot 9, the lubrication groove 9 is for storing lubricating oil；Preferably, the cross section of lubrication groove 9 is rectangle, the quantity root of lubrication groove 9
According to being set, preferably 1-2 lubrication groove 9 is respectively arranged in fixing sleeve 2 and sliding sleeve 3 in the present embodiment.Brake caliper 5 works
When, the lubricating oil stored in lubrication groove 9 contributes to the sliding of dust cover and brake caliper 5, play well extend dust cover and
The effect in 5 service life of brake caliper.
The embodiments of the present invention are described in detail above, but the content is only the preferable of the utility model
Embodiment should not be considered as limiting the scope of the present invention.It is made according to the scope of application of this utility model equal
Deng variation and improvement etc., should all still belong within the utility model covering scope of the utility model.
