Abstract

The utility model relates to a brake with a radiator for a motor vehicle. On the basis of an existing brake drum and an existing brake bottom plate, the utility model is additionally provided with a blade, a tuyere and a clearance tuyere, wherein, the tuyere is arranged on the brake bottom plate and/or the brake drum, and the blade is arranged on the brake drum. Accordingly, the utility model has the advantage of reasonable structural design; heat which is produced in the process of braking can be rapidly radiated, the vehicle conditions and the driving safety can be improved, etc.

Description

The motor vehicle brake that has sink

The utility model relates to a kind of break, particularly a kind of motor vehicle brake that has sink, and it mainly is applicable on the Motor Vehicle drum brake.

Motor vehicle brake of the prior art does not have sink, its brake structural sketch as shown in Figure 1, comprising brake drum 1 ＇ and braking bottom board 2 ＇, brake drum 1 ＇ is fixed on the wheel, and rotate with wheel, braking bottom board 2 ＇ then are fixed on the vehicle bridge; This brake structural that generally uses at present, there is following shortcoming in actual use in it: 1, structural design is reasonable inadequately, can not the adaline motor-car fast in the speed of a motor vehicle, load-carrying is many, the sort of bad working environment during down hill braking continuously, because its structural design is for being close to closed state, the heat accumulation that produces when making braking frictional plate and brake drum work friction is difficult for distributing, the workpiece temperature rise is fast, and heat fade is obvious, and brake drum loses the circle distortion easily; 2, the friction ractor owing to braking frictional plate at high temperature can descend rapidly, and all disappears until friction ractor with continuous rising of temperature, and also harmful thus vehicle condition and traffic safety easily cause driving accident.

The purpose of this utility model is to overcome existing above-mentioned deficiency of the prior art, and a kind of reasonable in design, the motor vehicle brake that has sink of distribute heat and long service life effectively are provided.

The purpose that the utility model proposed can be achieved through the following technical solutions: this break comprises brake drum and braking bottom board, brake drum and braking bottom board are complementary, its structural feature is to have the air port on braking bottom board and/or brake drum, brake drum is provided with fan blade, and forms the air port, gap between brake drum and braking bottom board.

The said fan blade of the utility model is fixed on the inwall of brake drum, so that heat can be distributed apace.

The utility model can be provided with a dust-proof cover at the place, air port, enters in the break from the air port to prevent earth.

The utility model compared with prior art, have the following advantages and effect: 1, reasonable in design, because design has fan blade and inlets and putlets of ventilation, make motor vehicle energy adapt to bad working environment, the heat that is produced in the Motor Vehicle braking process can distribute apace, can not damage because of heat accumulation causes break, working life is longer; 2, owing to solved this difficult problem of heat accumulation in the Motor Vehicle braking process, the heat that can give out break effectively and produced has guaranteed that it normally works effectively, and has improved vehicle condition and traffic safety, and the driving accident rate is descended.

Description of drawings is as follows:

Fig. 1 is the structural representation sketch of motor vehicle brake in the prior art.

Fig. 2 is a structural representation sketch of the present utility model.

Fig. 3 is the another kind of shape schematic representation of the utility model fan blade.

Fig. 4 is another kind of embodiment's schematic representation of the present utility model.

Following the utility model will be in conjunction with the accompanying drawings, and be described in further detail by embodiment.

Embodiment one:

Referring to Fig. 2, the utility model comprises brake drum 1 and braking bottom board 2, and brake drum 1 is complementary with braking bottom board 2, can distribute apace for make the heat of assembling in braking process, have air port 4 on brake drum 1 and the braking bottom board 2, brake drum 1 is provided with fan blade 3; Air port 4 on said braking bottom board 2 and the brake drum 1 quantity is set and size can be decided as the case may be, be prerequisite not influence intensity and fastness; Between brake drum 1 and braking bottom board 2, form air port, gap 5 naturally.Fan blade 3 is fixed on the inwall of brake drum 1, and quantity is set for it and size also can be decided as the case may be, is prerequisite with the intensity and the fastness of not interfering other parts, radiating efficiency is higher and does not influence brake drum 1; Fan blade 3 can strike out integrated type or split multidisc by bolton on brake drum 1, also the structure of available casting is cast on the inwall of brake drum 1; Simultaneously, the shape of fan blade 3 and setting angle also can design as the case may be, both shapes in the present embodiment, also shape or other shape among Fig. 3.If run into severe cold season, available tape paper is sealed air port 4, temperature is unlikely falls too lowly.In order to prevent that earth from entering air port 4, also can one dust-proof cover 6 be set 4 places in the air port, this dust-proof cover 6 can be a reticular structure.

During use, along with the rotation of wheel, brake drum 1 and fan blade 3 also rotate thereupon, just cause air pressure difference this moment, and air just can enter from air port 4 or air port, gap 5 thereupon, goes out from air port, gap 5 or air port 4 then, and take away wherein heat, heat is distributed apace.Embodiment two:

Referring to Fig. 4, in the present embodiment, on the keep plate 2 air port can be set, air port 4 is set on the brake drum 1, certainly, good conversely, promptly on brake drum 1, can not establish air port 4, but on braking bottom board 2 air port is set, air can enter from air port 4 or air port, gap 5 thus, and heat is taken out of from air port, gap 5 or air port 4 with air; All the other structures and working condition are identical with embodiment one.
