Description
Technical field
The utility model relates to motorcycle field, particularly a kind of motorcycle low noise brake hub.
Background technique
The brake hub of motorcycle is the device of carrying drum brake, and the friction pair of break is sealed in brake hub inside.Motorcycle is in braking process, and the mutual friction of friction pair phase produces dust, and these dust cannot be discharged in time, and dust constantly produces, is accumulated in friction pair contact surface, and braking effect is declined, and produces thorn ear noise when braking, causes noise pollution; When continuous use break, friction pair produces a large amount of heat and is difficult for shedding, and friction plate and brake hub is heated and causes heat fade, and frictional force reduces, and braking effect is along with the rising of temperature constantly reduces, and Braking efficiency reduces; In addition motorcycle in the process of moving brake hub after immersing water, can not be dried for a long time, during braking, the frictional force between friction pair reduces, Braking efficiency reduces, and easily causes security incident, is unfavorable for traffic safety.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of motorcycle low noise brake hub is provided, and its braking reliability is high, and during braking, noise is low, can effectively extend the working life of break and wheel hub.
The technical solution of the utility model is: a kind of motorcycle low noise brake hub, comprise aluminum alloy brake hub body, one axial end of described aluminum alloy brake hub body is provided with for the first cavity of break is installed, another axial end is provided with for the second cavity of buffer is installed, the center of circle of aluminum alloy brake hub body is provided with axis hole, axis hole two ends are separately installed with bearing, the inner peripheral wall of described the first cavity is embedded and is fixed with steel bushing, on the inner peripheral wall of described steel bushing, be laid with a plurality of along the axially extended dust discharging grooves of brake hub, the groove width of each dust discharging grooves is 2.5 ㎜～3.5 ㎜, groove depth is 0.4 ㎜～0.6 ㎜, the outer circle wall of described aluminum alloy brake hub body is provided with many around the radiating fin of circumference, distance between adjacent two radiating fin equates.
The quantity of described radiating fin is three, cooling surface area > 0.02 ㎡ of every radiating fin.
The quantity of described dust discharging grooves is four, and the groove width of each dust discharging grooves is 3.0 ㎜, and groove depth is 0.5 ㎜.
Adopt technique scheme: a kind of motorcycle low noise brake hub, comprise aluminum alloy brake hub body, one axial end of described aluminum alloy brake hub body is provided with for the first cavity of break is installed, another axial end is provided with for the second cavity of buffer is installed, the center of circle of aluminum alloy brake hub body is provided with axis hole, axis hole two ends are separately installed with bearing, for the central shaft of motor cycle rear wheel is installed.The inner peripheral wall of described the first cavity is embedded and is fixed with steel bushing, and steel bushing is for coordinating soon with the brake shoe of break.On the inner peripheral wall of described steel bushing, be laid with a plurality of along the axially extended dust discharging grooves of brake hub, the groove width of each dust discharging grooves is 2.5 ㎜～3.5 ㎜, groove depth is 0.4 ㎜～0.6 ㎜, the dust discharging grooves of this class specification is evenly set on steel bushing inner peripheral wall, the dust producing in the time of can effectively discharging friction pair braking, also can discharge the water that immerses brake hub, avoids producing thorn ear noise, do not affect the Braking efficiency of friction pair, guarantee traffic safety simultaneously yet.The outer circle wall of described aluminum alloy brake hub body is provided with many around the radiating fin of circumference, distance between adjacent two radiating fin equates, the heat producing during friction pair braking goes out by radiating fin Quick diffusing, prevent the excess Temperature of friction pair, effectively avoided friction pair because being heated, to cause heat fade, improve the braking effect of friction pair, guarantee traffic safety.
Below in conjunction with the drawings and specific embodiments, be further described.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is the P place enlarged view of Fig. 1.
In accompanying drawing, 1 is aluminum alloy brake hub body, and 2 is the first cavity, and 3 is the second cavity, and 4 is axis hole, and 5 is bearing, and 6 is steel bushing, and 7 is dust discharging grooves, and 8 is radiating fin.
Embodiment
Referring to Fig. 1 to Fig. 3, a kind of motorcycle low noise brake hub, comprise aluminum alloy brake hub body 1, one axial end of described aluminum alloy brake hub body 1 is provided with for the first cavity 2 of break is installed, another axial end is provided with the axial depth that is greater than the second cavity 3 for the axial depth of the second cavity 3, the first cavitys 2 of buffer is installed.The center of circle of aluminum alloy brake hub body 1 is provided with axis hole 4, and axis hole 4 two ends are separately installed with between 5, two bearings 5 of bearing and are also provided with an axle sleeve.The inner peripheral wall of described the first cavity 2 is embedded and is fixed with steel bushing 6, and steel bushing 6 is embedded into the first cavity when aluminum alloy brake hub body casting.On the inner peripheral wall of described steel bushing 6, be laid with a plurality of along the axially extended dust discharging grooves 7 of brake hub, the groove width of each dust discharging grooves 7 is 2.5 ㎜～3.5 ㎜, groove depth is 0.4 ㎜～0.6 ㎜, optimum, the quantity of described dust discharging grooves 7 is four, the groove width of each dust discharging grooves 7 is 3.0 ㎜, groove depth is 0.5 ㎜, the dust granules that dust discharging grooves produces in the time of can effectively discharging friction pair braking, also the water that immerses brake hub can be discharged, while avoiding braking, produce thorn ear noise, also do not affect the Braking efficiency of friction pair simultaneously, guarantee traffic safety.The outer circle wall of described aluminum alloy brake hub body 1 is provided with many around the radiating fin 8 of circumference, distance between adjacent two radiating fin 8 equates, for guaranteeing good radiating effect, cooling surface area > 0.02 ㎡ of every radiating fin 8, the quantity of radiating fin 8 is three.
