Abstract
The utility model relates to a can't discharge to current brake drum surface abrasive material to cause braking moment to reduce a brake drum with automatic ash of arranging who causes driving brake failure easily and provide in the automobile parts field. Including the brake drum body, the fricative one side of production is equipped with the groove of running through whole friction surface between its and the friction disc on the brake drum body, inboard outside extension of this groove self -retention drum body, and extending direction is along brake drum body rotation in the opposite direction's direction. The opening portion groove width in groove will be less than the groove width of inslot portion. Opposite direction one side that the groove opening is located brake drum body rotation direction is sharp -pointed acute angle structure. The utility model discloses increase on the friction disc between brake drum and friction disc and arrange the ash chute, utilize centrifugation principle to make the abrasive material in the brake drum discharge along arranging the ash chute, make brake drum and friction disc in close contact with, produce the biggest brake force, make the steady safe parking of vehicle fast, row's ash chute is opened at the brake drum port, does not influence the life of brake drum.
Description
Technical field
This utility model belongs to auto parts and components field, more particularly to a kind of brake drum.
Background technology
Brake drum is the fricting couple piece of drum brake, in addition to it should have as the strength and stiffness required for component, also
There should be a coefficient of friction as high and stable as possible, and appropriate wearability, thermostability, thermal diffusivity and thermal capacity etc..
By behaviour in service and Research on Structural Analysis to brake drum；It was found that the mill of brake operationally brake drum surface
Material cannot be discharged, and be deposited between friction plate and brake drum, greatly reduce braking moment, make service brake fail, and cause car
Sideslip, leads to the vehicle accident of bitterness.
Utility model content
The purpose of this utility model is cannot to discharge to cause braking moment to reduce easily for existing brake drum surface abrasive material
A kind of brake drum with automatic removing dust for causing service brake to fail and providing.
To achieve these goals, technical solution adopted in the utility model is：
A kind of brake drum with automatic removing dust, including brake drum body, it is between friction plate on brake drum body
The one side of generation friction is provided with the groove through whole rubbing surface, and groove self-retention drum body inner side stretches out, and bearing of trend
It is along the contrary direction of brake drum body rotation direction.
The opening portion groove width of described groove is less than the groove width inside groove.
It is sharp acuter angles that described channel opening portion is located at the contrary direction side of brake drum body rotation direction.
The slot cross-section is in dovetail channel-shaped, and described groove is more than one.
It is provided with through the hole of whole brake drum in the bottom of groove, hole is at least one.
The beneficial effects of the utility model：This utility model increases ash discharge on the friction plate between brake drum and friction plate
Groove, makes the abrasive material in brake drum discharge along ash discharge groove using centrifugal principle, brake drum is in close contact with friction plate, produces maximum
Brake force, quickly makes the steady emergency of vehicle；Ash discharge groove is opened in brake drum port, does not affect the service life of brake drum.
Description of the drawings
Fig. 1 is this utility model front view；
Fig. 2 is sectional view of the present utility model.
Specific embodiment
This utility model is described further with reference to embodiment.
Embodiment
A kind of brake drum with automatic removing dust as depicted in figs. 1 and 2, including brake drum body 1, it should be noted that
Its one side that friction is produced between friction plate is provided with the groove 2 through whole rubbing surface on brake drum body, the self-retention of groove 2
Drum body inner side stretches out, and bearing of trend is along the contrary direction of brake drum body rotation direction.The groove bearing of trend
It is specifically designed and is able to more preferable ash discharge, the opening portion groove width of described groove is less than the groove width inside groove.The design
It is to store more dusts.It is point that described channel opening portion is located at the contrary direction side of brake drum body rotation direction
Sharp acuter angles.Good shear action is carried out to the dust of Friction Disk Surface using sharp angle, so as to more preferable ash discharge,
Friction Disk Surface collection ash phenomenon will not be produced.The slot cross-section is in dovetail channel-shaped, and described groove is more than one.Set in the bottom of groove
Have through the hole of whole brake drum, hole is at least one.The design in the hole, will while brake drum is rotated and produces centrifugal action
Dust is discharged by the hole, is further ensured that being fully contacted between brake drum and friction plate.
Ultimate principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Simply illustrate principle of the present utility model, it is in the art common on the premise of without departing from this utility model spirit and scope
Technical staff simple change and replacement be all within protection domain of the present utility model.
