Description
Technical field
The present invention relates to electric vehicle motor drum brake end cap field more particularly to a kind of motor drum brake ends with capillary groove
Lid.
Background technology
China is electric vehicle production and the big country used.Since in recent years, master that electric vehicle is gone on a journey as people's short distance
Want walking-replacing tool.Key fitment of the electric vehicle motor as electric vehicle provides necessary power for electric vehicle, at whole electronic two
Extremely important effect is played in wheel.So the reliability of electric vehicle brake is very important.Current electric vehicle on the market
Brake modes are broadly divided into drum brake, disc brake and three kinds of the brake that rises.Drum brake is a kind of very common brake modes, and use environment is opposite
Compare badly, to ensure the work of its energy normal table, the waterproof, sediment prevention performance requirement to it are higher.
A kind of drum brake waterproof construction is disclosed in Chinese patent application prospectus, CN 203717736U, including
Admittedly the drum brake circle being enough on wheel and the drum brake lid being installed on drum brake circle, wherein, drum brake is covered to be set with the joint of drum brake circle
At least twice waterproof boss is equipped with, is corresponded on waterproof boss in being provided with waterproof step on drum brake circle, waterproof boss is close to set
In on waterproof step, and drum brake lid waterproof groove is formed between waterproof boss.Above-mentioned drum brake waterproof construction in drum brake in specially setting
The waterproof construction being made of waterproof boss and waterproof step is not easy to flow into drum brake circle with the water for ensuring external, and water resistance is good,
Ensure the work of drum brake normal table, extend the use of drum brake.It is but existing since the position of drum brake brake is not enclosed construction
It is difficult to ensure that water will not enter normal danger with silt during routine use, water and silt can be from brakes and drum for drum brake brake
Enter in gap among brake end cap, and cause skidding decreased effectiveness.
Therefore, those skilled in the art is dedicated to developing a kind of New-type motor vehicle electrical machinery drum brake end cap, it is ensured that drum brake is stopped
Railway carriage is with iron ring drying in drum lid drum chamber without silt, it is ensured that the reliability and service life of drum brake brake.
Invention content
Drum brake end cap with conventional outer capillary groove, the constitution water and silt can be from brakes and the gap among drum brake end cap
Middle entrance, and cause skidding decreased effectiveness.In view of the drawbacks described above of the prior art, technology to be solved by this invention is asked
Topic is the waterproof of electric motor vehicle drum brake, sediment prevention performance.
To achieve the above object, the present invention provides a kind of electric vehicle motor drum brake end caps.
Conventional outer capillary groove, inner waterproofing slot are provided on drum brake end cap ontology.When water and silt are from brake and drum brake end cap
Between gap enter inner waterproofing groove location, due to the barrier water of cell wall on the inside of inner waterproofing slot slot bottom and inner waterproofing slot and silt without
Method enters further into drum brake end cap iron ring position, when drum brake end cap turns together with motor in motor normal course of operation
It is dynamic, the water entered in the cell wall of inner waterproofing slot inside and silt is driven to rotate together, since centrifugal action water and silt are thrown toward
Cell wall on the outside of inner waterproofing slot；And cell wall taper direction discharges water and silt on the outside of inner waterproofing slot.
Further, in embodiments of the present invention, inner waterproofing slot cross section can be designed as it is rectangular, arc-shaped, three
Angular and trapezoidal, i.e., one side of sink is skewed, can be built up to avoid water and silt in bottom of gullet.
Further, on the inside of inner waterproofing slot cell wall can one lower edge of band, this kind of structure can further prevent water and silt into
Enter inside drum brake.
It further, can be with rectangular, arc-shaped, triangle, trapezoidal waterproof along structure under cell wall on the inside of inner waterproofing slot
Slot design is combined, so as to obtain the effect of better waterproof and sediment prevention.
The present invention provides a kind of electric vehicle motor drum brake end cap, the design of inner waterproofing slot can effectively prevent water and silt
Into electric motor vehicle drum brake normal danger, it is ensured that drum brake brake rubber block is with iron ring drying in drum lid drum chamber without silt, it is ensured that drum brake is braked
Reliability and service life.
The technique effect of the design of the present invention, concrete structure and generation is described further below with reference to attached drawing, with
It is fully understood from the purpose of the present invention, feature and effect.
