Abstract

The utility model relates to the brake member of automobile, specifically a kind of compound brake drum being provided with ring-type dead turn inside drum shell, comprise bulging shell and dead turn, wherein dead turn is arranged at inside bulging shell, described dead turn comprises two-layer up and down, every layer of dead turn is ring structure, be equipped with for preventing described dead turn from producing the wire casing losing circle phenomenon because expanding with heat and contract with cold in the inner friction surface of every layer of dead turn, the setting and the wire casing on two-layer dead turn staggers respectively, multiple radiation hole is evenly equipped with in the middle part of drum shell, on every layer of dead turn, be provided with the through hole communicated with the radiation hole on drum shell near one end of another layer of dead turn at each wire casing, described like this radiation hole just can in heat radiation simultaneously for discharging friction waste residue.Bulging shell of the present utility model is not easy to occur breakage, long service life, and dead turn is changed convenient, and replacement cost greatly reduces.

Description

A kind of compound brake drum
Technical field
The utility model relates to the brake member of automobile, specifically a kind of compound brake drum being provided with ring-type dead turn inside drum shell.
Background technique
Brake drum is widely used a kind of brake member on automobile, and during brake, the brake shoe iron assembly being arranged at brake drum inside opens and rubs with brake drum inner surface and produces resistance and realize braking, thus makes vehicle deceleration or the parking of traveling.Brake drum is very easy to damage due to severe friction, needs periodic replacement, and each changes cumbersome and cost is higher.Some brake drum in addition, as drum brake drum widely used on vehicle, its inside is provided with cast iron in polylith arc, after brake shoe iron assembly opens namely with cast iron friction in described arc, owing to expanding with heat and contract with cold, dispel the heat bad, in arc, the edge of cast iron easily occurs that rake angle and brake drum lose circle phenomenon, affects the use of brake drum.
Model utility content
The purpose of this utility model is to provide a kind of compound brake drum, dead turn is provided with inside drum shell, and described dead turn is provided with wire casing prevents dead turn from producing the obstructed core phenomenon of mistake circle owing to expanding with heat and contract with cold, described dead turn is ring-type in addition, there will not be rake angle phenomenon, make brake drum be not easy to occur breakage, replacing is easy and replacement cost is low.
The purpose of this utility model is achieved through the following technical solutions:
A kind of compound brake drum, comprise bulging shell and dead turn, wherein dead turn is arranged at inside bulging shell, drum shell being evenly equipped with multiple for dispelling the heat and discharge the radiation hole of friction waste residue, being evenly equipped with for preventing dead turn to produce the wire casing losing and justify phenomenon because expanding with heat and contract with cold in the inner friction surface of dead turn.
Described dead turn comprises two-layer up and down, and every layer of dead turn is ring structure.
Be equipped with described for preventing dead turn from producing the wire casing losing circle phenomenon because expanding with heat and contract with cold, the setting and the wire casing on two-layer dead turn staggers respectively in the inner friction surface of every layer of dead turn.
Be evenly equipped with multiple radiation hole in the middle part of described bulging shell, on every layer of dead turn, be provided with the through hole communicated with the radiation hole on drum shell near one end of another layer of dead turn at each wire casing.
Described bulging shell and dead turn are fixed by bolt or rivet.
Advantage of the present utility model and good effect are:
1, the utility model is provided with the dead turn of ring-type in drum shell, brake shoe iron assembly and the direct contact friction of described dead turn, the utility model drum shell does not come in contact with brake shoe iron assembly, drum shell is not easy to occur breakage, long service life, only need to regularly replace dead turn, it is convenient to change, and replacement cost greatly reduces.
2, the utility model is provided with wire casing on dead turn, lose the obstructed core phenomenon of circle, and the utility model is provided with radiation hole, to reduce the impact of expanding with heat and contract with cold further on drum shell and dead turn to prevent from producing owing to expanding with heat and contract with cold.
3, the dead turn in the utility model is doughnut-shaped monolithic casting, there will not be rake angle phenomenon, and the setting and the wire casing on two-layer dead turn staggers respectively, better adds compound brake drum Braking efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the dead turn structural representation in Fig. 1.
Wherein, 1 is drum shell, and 2 is dead turn, and 3 is wire casing, and 4 is radiation hole, and 5 is fastening bolt holes.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises bulging shell 1 and dead turn 2, wherein said bulging shell 1 is cast for ZG340 or ZG400 material and is formed, and described bulging shell 1 is that disk body and cylindrical shell are one-body molded when manufacturing, described dead turn 2 is installed on inside bulging shell 1 by bolt or rivet, described dead turn 2 comprises two-layer up and down, and every layer of dead turn 2 is the ring structure of integral casting forming, and every layer of dead turn 2 is evenly equipped with fastening bolt holes 5.As shown in Fig. 1 ~ 2, multiple wire casing 3 is equipped with in the inner friction surface of every layer of dead turn 2, when friction temperature rising makes dead turn 2 heat expansion, namely the cell wall of each wire casing 3 both sides expands to prevent dead turn 2 from producing owing to expanding with heat and contract with cold and loses circle phenomenon in groove, wire casing 3 on every layer of dead turn 2 is uniformly distributed, the setting and the wire casing 3 on two-layer dead turn 2 staggers respectively, substantially increases working life.
Multiple radiation hole 4 is evenly equipped with in the middle part of described bulging shell 1, on every layer of dead turn 2, be provided with the through hole communicated with the radiation hole 4 on drum shell 1 near one end of another layer of dead turn 2 at each wire casing 3, described like this radiation hole 4 also can discharge friction waste residue while heat radiation, in the present embodiment, drum shell 1 is evenly equipped with 6 radiation holes altogether.
Working principle of the present utility model is:
Brake shoe iron assembly rubs with the dead turn 2 roused inside shell 1 when opening braking and produces friction brakes, because dead turn 2 is integral casting forming, be equipped with increase fatigue proof alloy raw material, wear-resisting not fragile, even and if dead turn 2 damage, dead turn 2 is only needed to change, without the need to changing bulging shell 1, replacing is convenient and cost is lower, drum shell 1 is provided with radiation hole 4 and dispels the heat, and friction waste residue can be discharged, improve the working life of drum shell 1 further.
