Abstract
A groove-type radiating braking drum comprises a braking drum body and a wheel spoke. A first groove is formed in the braking face on the inner side of the braking drum. One end of the first groove extends out of the wheel spoke. A second groove symmetrically matched with the first groove is formed in a braking shoe. The groove-type radiating braking drum is simple in structure, convenient to use and good in radiating effect.
Description
Technical field
The utility model relates to a kind of brake drum, relates in particular to a kind of groove type radiation brake drum.
Background technique
In drum shoe brake, automobile is to be braked by brake shoe and the mutual fricative resistance of brake drum.In the time excessively frequently braking, the surface temperature of braking surface can reach 300 to 500 degree, and heat cannot distribute, and brake drum likely can happen suddenly and break, and affects braking effect; In addition, the impurity on brake drum, dust are not easy cleaning, also can have a strong impact on braking effect.
Chinese patent notice of authorization number is CN 201502649U, notice of authorization day be the utility model patent of on 06 09th, 2010 disclose a kind of at rubbing surface with many spiral groove structured brake drums, according to the mechanical friction thermomechanics interface theory of engagement, by setting up helical groove, change broad width Surface of action into vertically hung scroll formula helical toothing band, make friction pair become band contact by face contact, strengthened the thermal diffusivity of bulging body self and the ability of opposing dilatancy, groove also possesses to be implemented to cool down, absorb heat and the function such as quick heat extraction in the friction of shoe plate and drum surface.
Although said apparatus has used many helical grooves on rubbing surface, and is provided with radiation hole, the thermal diffusivity of bulging body self and the ability of opposing dilatancy are effectively strengthened.But in this design, heat radiation relies on radiation hole completely, and groove is still positioned at braking surface inside, and thermal diffusivity is general, and the impurity of inside grooves and dust be not easy to discharge, and had a strong impact on braking effect.
Summary of the invention
The purpose of this utility model is to overcome in prior art brake drum to be difficult for heat radiation, clean difficult problem, and a kind of groove type radiation brake drum of simple in structure, easy to use, good heat dissipation effect is provided.
For realizing above object, technical solution of the present utility model is: a kind of groove type radiation brake drum, comprise brake drum and spoke, on the braking surface of described brake drum inner side, be provided with groove No. one, No. one groove one end trailing wheel spoke is protruding, has and symmetrical No. two grooves that coordinate of groove on brake shoe.
Described inside brake drum is provided with supporting rib, on every supporting rib, has cyclic water channel, is provided with circular hole on supporting rib, and circular hole is not point-blank.
Described brake drum edge is provided with water injection hole and decompressor.
On described spoke, be provided with radiation hole.
Compared with prior art, the utlity model has following beneficial effect:
1, on the braking surface of brake drum inner side, be provided with groove No. one, groove one end trailing wheel spoke is protruding due to No. one, and on brake shoe, have and symmetrical No. two grooves that coordinate of groove, the heat that brake produces like this can be discharged in air via the gap forming between a groove and No. two grooves, greatly reduces the surface temperature of braking surface; In addition, dust, the dust etc. of braking surface also can be from being discharged by the gap forming between a groove and No. two grooves, guaranteed the clean dry of braking surface, improved the stability of brake.
2, inside brake drum is provided with supporting rib, on supporting rib, there is circular hole, brake drum edge is provided with water injection hole and decompressor, before driving, cold water can be injected to brake drum from water injection hole, cold water circulates in drum via the cyclic water channel on supporting rib, thereby realize, brake drum is lowered the temperature.
3, due to being used in conjunction with an of groove and No. two grooves, before making, the face friction of brake drum becomes band friction, and frictional force is increased, and safety coefficient is higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Fig. 3 is the structural representation of brake shoe in the utility model.
In figure: brake drum 1,2, numbers grooves 3 of braking surface, spoke 4, circular hole 5, water injection hole 6, decompressor 7, radiation hole 8,9, No. two grooves 10 of brake shoe, supporting rib 11.
Embodiment
Below in conjunction with accompanying drawing explanation and embodiment, the utility model is described in further detail:
Referring to Fig. 1 to Fig. 3, a kind of groove type radiation brake drum, comprises brake drum 1 and spoke 4, on the braking surface 2 of described brake drum 1 inner side, is provided with groove 3 No. one, No. one groove 3 one end are protruding from spoke 4, have and symmetrical No. two grooves 10 that coordinate of groove 3 on brake shoe 9.
Described brake drum 1 inside is provided with supporting rib 11, on every supporting rib 11, has cyclic water channel, is provided with circular hole 5 on supporting rib 11, and circular hole 5 is not point-blank.
Described brake drum 1 edge is provided with water injection hole 6 and decompressor 7.
On described spoke 4, be provided with radiation hole 8.
The utility model is provided with No. one groove 3 on the braking surface 2 of brake drum 1 inner side, groove 3 one end are protruding from spoke 4 one sides due to No. one, and brake shoe matches with brake drum 1 again, and on brake shoe 9, have and symmetrical No. two grooves 10 that coordinate of groove 3, the heat that brake produces like this can be discharged in air via the gap forming between a groove 3 and No. two grooves 10, greatly reduces the surface temperature of braking surface 2; In addition, dust, the dust etc. of braking surface 2 also can be discharged from gap, has guaranteed the clean dry of braking surface 2, has improved the stability of brake.Due to being used in conjunction with of a groove 3 and No. two grooves 10, before making, the face friction of brake drum 1 becomes band friction, and frictional force is increased, and safety coefficient is higher.In addition, the utility model brake drum 1 inside is provided with supporting rib 11, on supporting rib 11, there is circular hole 5, brake drum 1 edge is provided with water injection hole 6 and decompressor 7, before driving, cold water can be injected to brake drum 1 from water injection hole 6, cold water circulates in drum via the cyclic water channel on supporting rib 11, and the high temperature in drum is discharged by radiation hole 8, the temperature of drum body, by cooling water temperature, is really accomplished water-cooled and the air-cooled object combining.The utility model is simple in structure, easy to use, good heat dissipation effect.
