Abstract
The utility model relates to a brake drum with a meshed groove. The brake drum is used for being rubbed with a brake shoe mutually so as to brake wheels. The meshed groove used for exhausting, discharging chips and radiating is arranged on the inner surface of the brake drum, thereby strengthening exhausting, chip discharging and radiating effects during braking, reducing deformation of the brake drum, namely reducing stroke of a brake pedal, decreasing brake noise and temperature of friction liners, and prolonging service lives of the friction liners and the brake drum.
Description
Technical field
The utility model relates to a kind of brake drum with netted groove.
Background technique
Brake drum is used for matching with brake shoe, the cylindrical form interior surface by the friction facing on the brake shoe and brake drum mutually mutual friction so that wheel is implemented braking.Yet, existing brake drum can produce a large amount of gas, heat and chip when braking work, because the existence of gas, heat and chip, make the frictional force of friction facing and brake drum diminish, can increase the amount of deformation of brake drum, just increase the stroke of brake petal, can increase brake noise simultaneously, improve the temperature of friction facing, shorten the life-span of friction facing and brake drum.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of stroke, minimizing brake noise that reduces brake petal, can increase the brake drum with netted groove in working life simultaneously.The utility model is achieved through the following technical solutions:
A kind of brake drum with netted groove of the present utility model is used for that mutual friction is to implement braking to wheel mutually with brake shoe, and described brake drum internal surface is provided with the netted groove that is used for exhaust, chip removal and heat extraction.
As preferably, the degree of depth of described netted groove is 1～5mm.
As preferably, described brake drum posterior face can produce the stiffening rib of certain air quantity when being provided with rotation.
As preferably, described brake drum posterior face is provided with and contacts with wheel rim, is used to reduce the surface of contact that wheel rim contacts with brake drum.
A kind of brake drum of the present utility model with netted groove, because described brake drum internal surface is provided with the netted groove that is used for exhaust, chip removal and heat extraction, exhaust, chip removal and heat extraction during with increase braking work, reduce the amount of deformation of brake drum, just reduce the stroke of brake petal, reduce brake noise, reduce the temperature of friction facing, prolong the life-span of friction facing and brake drum.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the schematic perspective view of the brake drum of the netted groove of the utility model band;
Fig. 2 is the schematic perspective view that the brake drum of the netted groove of the utility model band matches with brake shoe;
Fig. 3 is the schematic perspective view of another angle shown in Figure 1.
Embodiment
Referring to figs. 1 through shown in Figure 3, a kind of brake drum 2 of the present utility model with netted groove, be used for brake shoe 1 mutually mutual friction wheel is implemented braking, described brake drum internal surface 20 is provided with the netted groove 21 that is used for exhaust, chip removal and heat extraction, exhaust, chip removal and heat extraction during with increase braking work, the amount of deformation of minimizing brake drum, just reduce the stroke of brake petal, reduce brake noise, reduce the temperature of friction facing, prolong the life-span of friction facing and brake drum.In the present embodiment, the degree of depth of described netted groove is 1～5mm.
Wherein, described brake drum posterior face 22 can produce the stiffening rib 23 of certain air quantity when being provided with rotation, help heat radiation, improves intensity simultaneously.Described brake drum posterior face 22 is provided with and contacts with wheel rim, is used to reduce the surface of contact 24 that wheel rim contacts with brake drum 2, reduces heat-conducting area.
A kind of brake drum of the present utility model with netted groove, because described brake drum internal surface is provided with the netted groove that is used for exhaust, chip removal and heat extraction, exhaust, chip removal and heat extraction during with increase braking work, reduce the amount of deformation of brake drum, just reduce the stroke of brake petal, reduce brake noise, reduce the temperature of friction facing, prolong the life-span of friction facing and brake drum.
The foregoing description; it is an example of the present utility model; be not to be used for limiting enforcement of the present utility model and interest field, all and the described same content of the utility model claim or the technological scheme that is equal to all should be included in the utility model protection domain.
