Description
Technical field
The utility model relates to automotive brake, relates in particular to a kind of automobile drum brake.
Background technique
Automobile is the traffic tool conventional in daily life.The braking of automobile completes by break.The kind of automotive brake has a lot, one of principal mode that wherein drum brake is current vehicle brake.Drum brake is made up of component such as base plate, brake drum, brake shoe, wheel cylinder (being called again brake cylinder or master cylinder), return spring and locating studs.Chinese Patent Application No. 2010102189202, within open day, be January 11 in 2012 day, the basic structure of drum brake disclosed in being called the patent document of " drum brake ", the working procedure of drum brake is: in the time of braking, wheelcylinder piston promotes brake shoe compressing brake drum, brake drum is subject to friction eceleration, forces wheel to stop operating.
Existing drum brake has the following disadvantages: under sleet microthermal climate condition and while causing inner inlet to freeze, brake functionality can lose efficacy, and vehicle can not normally use.At present, adopt to knock to make brake inside freeze cracked or water hot water the modes such as brake inside ice-out are thawed, existing thawing mode is very inconvenient.
Model utility content
The utility model provides the automobile drum brake that can thaw that a kind of humidity resistance of cable is good, the inconvenient problem of thawing after having solved existing drum brake and freezing.
Above technical problem solves by following technical proposal: a kind of automobile drum brake, comprise brake drum, the a pair of brake shoe that is positioned at inside brake drum coordinating with brake drum, electric heater, to the power switch of the cable of electric heater power supply and the electric break-make of control electric heater, described electric heater is installed on described brake shoe, described power switch is installed on automobile bodies, described cable comprises plastic outer sleeve, be located in the conductor wire core in outer sleeve and be wrapped in the insulator on conductor wire core, the outer surface of described outer sleeve is provided with the circular groove of the circumferential extension axial distribution along outer sleeve being spaced apart from each other, the internal surface of described outer sleeve is provided with the bulge loop of the circumferential extension axial distribution along oversheath being spaced apart from each other, the position of described circular groove and described bulge loop aligns.When break produces freezing and can not normally work and be, make the same power connection of electric heater by switch, thereby electric heater obtains and produces heat the ice-out in break is fallen electric.At the outer surface of outer sleeve, spaced circular groove is set, internal surface at outer sleeve arranges bulge loop corresponding to the position of circular groove, not only make the bending increased frequency of cable, crooked process radius reduces, and each one of bulge loop formation stops moisture axially entering cable inside and preventing the isolation zone that axially drop out of isolation layer fragment along cable along cable, moisture is difficult for axially entering cable inside along cable, in the time that the isolation layer of cable has fragmentation, fragment can maintain original position and can axially not drop out along cable, carry the humidity resistance of electricity to the cable of heating equipment thereby improved.If only form groove and do not form projection at the internal surface of outer sleeve at the outer surface of outer sleeve, although the flexibility of cable is made moderate progress, do not possess protection against the tide and prevent the effect that fragment drops out.If when groove is the form of the helical structure that is connected together, in the process cable being bent, when inflection point place one side is groove, opposite side can be muscle, when axial tension, cable easily produces structural damage and bending curvature is less, and from this structure, when groove is spaced structural type, in the process that cable is bent, the same time slot in both sides, inflection point place, curvature when longitudinal stretching causes structural damage and increases cable bend when therefore structure can be improved bending.
