Abstract
The utility model discloses a pneumatic diaphragm used for a dual-motor hybrid power brake clutch. The pneumatic diaphragm used for the dual-motor hybrid power brake clutch comprises a diaphragm body, the diaphragm body is made of a hydrogenated nitrile rubber material and composed of an inner circular ring and an outer circular ring, and a plurality of installing holes are formed in the inner circular ring and the outer circular ring respectively; the right end of the inner circular ring and the left end of the outer circular ring extend downward respectively to form an inner lower block and an outer lower block; the inner lower block and the outer lower block extend aslant towards the inner side to form an inner inclined block and an outer inclined block; the inner inclined block and the outer inclined block are connected through a transverse block, so that an air cavity is formed between the inner circular ring and the outer circular ring. The pneumatic diaphragm is simple in structure, the highest use temperature of rubber of the hydrogenated nitrile rubber material is 150 DEG C, the lowest use temperature is -10 DEG C, the pneumatic diaphragm is resistant to gear lubricant, not prone to damage and long in service life.
Description
Technical field
The utility model relates to clutch field, refers more particularly to a kind of pneumatic diaphragm for double-motor hybrid brake coupling.
Background technique
Existing diaphragm kind is a lot, but all can not be high temperature resistant, ability gear lubricant not, and cracky, and also rigidity is large, and structure shape is unreasonable, easily drawing crack.
Model utility content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art and a kind of simple in structure, practical pneumatic diaphragm for double-motor hybrid brake coupling is provided.
The utility model is realized in the following way:
For a pneumatic diaphragm for double-motor hybrid brake coupling, comprise diaphragm body 1, it is characterized in that: described diaphragm body 1 adopts hydrogenation nitrile rubber material to make, and it is comprised of interior annulus 11 and outer toroid 12;
The left end of the right-hand member of described interior annulus 11 and outer toroid 12 extends to form respectively interior lower 111 and outside lower 121 downwards; Described interior lower 111 and outside lower 121 be oblique interior skewback 112 and the outer skewback 122 of extending to form to the inside respectively; Between described interior skewback 112 and outer skewback 122, by horizontal piece 13, be connected, make to form between interior annulus 11 and outer toroid 12 gas chamber 4.
Preferably, the surface of described interior annulus 11 and outer toroid 12 is respectively equipped with ring packing muscle 5.
Preferably, between described interior lower 111 and interior skewback 112, form an interior circular groove 6.
Preferably, between described outside lower 121 and outer skewback 122, form a peripheral groove 7.
Preferably, in interior annulus 11 and outer toroid 12, be respectively equipped with some mounting holes 3.
The beneficial effects of the utility model are: simple in structure, hydrogenation nitrile rubber material rubber is used 150 degrees Celsius of maximum temperatures, minimum temperature-10 degree Celsius, and resistance to gear lubricant, not fragile, long service life.
Accompanying drawing explanation
Fig. 1 the utility model structural section plan view;
Fig. 2 the utility model structure plan view.
Embodiment
Now by reference to the accompanying drawings, the utility model embodiment is described in detail in detail:
As shown in Figure 1 and Figure 2, a kind of pneumatic diaphragm for double-motor hybrid brake coupling, comprise diaphragm body 1, diaphragm body 1 adopts hydrogenation nitrile rubber material to make, it is comprised of interior annulus 11 and outer toroid 12, in interior annulus 11 and outer toroid 12, be respectively equipped with some mounting holes 3, for the installation of diaphragm body 1; The left end of the right-hand member of interior annulus 11 and outer toroid 12 extends to form respectively interior lower 111 and outside lower 121 downwards; In lower piece 111 and outside lower 121 oblique interior skewback 112 and the outer skewback 122 of extending to form to the inside respectively; Between interior skewback 112 and outer skewback 122, by horizontal piece 13, be connected, make to form between interior annulus 11 and outer toroid 12 gas chamber 4.
The utility model, in order to guarantee the sealing of gas chamber 4, is respectively equipped with ring packing muscle 5 on the surface of interior annulus 11 and outer toroid 12.
The utility model is in order to guarantee the air capacity of gas chamber 4, between interior lower 111 and interior skewback 112, forms an interior circular groove 6.
The utility model is in order to guarantee the air capacity of gas chamber 4, between outside lower 121 and outer skewback 122, forms a peripheral groove 7.
The utility model adopts hydrogenation nitrile rubber material rubber to make, it uses 150 degrees Celsius of maximum temperatures, minimum temperature-10 degree Celsius, and resistance to gear lubricant, pneumatic diaphragm surface should be bright and clean, pore-free, pit, crackle, in pneumatic diaphragm without dust granules, bubble, be mingled with, rigidity is little, and material is soft, and tear strength is checked and accepted by this trade mark material rubber parts of country.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
