Abstract
The utility model relates to components for the front axle of an automobile, in particular to a disc brake for the front axle of the automobile. The utility model mainly aims to solve the technical problems in the prior art that the conventional drum brake has friction assisting potential, so that the efficiency of the brake is more unstable due to great influence of the friction coefficient, and the amount of thermal expansion of the brake disc in the thickness direction is great, so that the clearance of the brake is increased remarkably to cause overlarge stroke of the brake pedal. The disc brake comprises a front axle (1); and brakes (2) are respectively arranged at the two ends of the front axle. The disc brake is characterized in that the brakes (2) adopt 19.5-inch brakes; a brake disc (3) is arranged on the outer side of each brake; a hub (4) is fixed in each brake disc; an air chamber (5) is connected to each hub; both the brakes (2) are hinged at the two ends of a track rod (6) through transmission rods; and a drag link arm (7) is also connected to each brake.
Description
Technical field
The utility model relates to a kind of component of automobile front axle, especially relates to a kind of automobile front axle disk type braker.
Background technique
At present common automobile front axle adopts drum brake assembly to brake.Drum brake assembly mainly comprises wheel cylinder assembly and braking bottom board assembly, and the wheel cylinder assembly is contained on the braking bottom board assembly, and connects the shoe plate of braking usefulness.Chinese patent discloses a kind of automobile drum brake (notice of authorization number: CN 200985972Y), it is mainly by the drum body, shoes reaches the ferodo that tightly is overlying on the shoes appearance, cam is formed, two be relatively the semicircle arcuation shoes quiet end each be loaded on axle sleeve piece stationary axle and be rotatably assorted, the moved end is contacted by the Returnning spring application of force and cam, the variable position of the axis hole of the shoes that itself and stationary axle are rotatably assorted changes, the axle sleeve that shoes and stationary axle are rotatably assorted is made a plurality of independent axle sleeve piece that the position, hole is moved on gradually, axle sleeve is packaged in sleeve block, be shaped on two cavity volumes that cooperate with the axle sleeve piece of being separated by in the sleeve block, pack into and sleeve block and axle sleeve piece are fixed by screw by cover plate behind the axle sleeve piece, the axle sleeve piece has the 2-3 piece separately, the axis hole position of each axle sleeve piece is moved on successively, the quiet end of shoes has the edge hole identical with axle sleeve piece peripheral shape, the axle sleeve piece is embedded in the hole, the identical axle sleeve piece in preparation every axis hole position of polylith, the axle sleeve block length to size less than the length of sleeve block content cavity to size, pad is inserted for pad in its remaining gap, as required, pad is inserted filled up in axle sleeve piece upper end or lower end or upper and lower end.But this drum brake has friction helps the gesture effect, thereby brake efficiency is subjected to the influence of friction factor bigger, usefulness is unstable, and brake disc is very big along the thermal expansion amount of thickness direction, makes the obvious increase of brake clearance and causes brake-pedal travel excessive.
The model utility content
The utility model provides a kind of automobile front axle disk type braker, it mainly is to solve the existing in prior technology drum brake to have friction and help the gesture effect, thereby brake efficiency is subjected to the influence of friction factor bigger, usefulness is unstable, and brake disc is very big along the thermal expansion amount of thickness direction, brake clearance is obviously increased and causes the technical problem of the excessive grade of brake-pedal travel.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of automobile front axle disk type braker of the present utility model, comprise front axle, the front axle two ends respectively are provided with break and it is characterized in that described break is 19.5 inches breaks, the outside of break is provided with brake disc, the brake disc internal fixation has wheel hub, is connected with air chamber on the wheel hub, and air chamber is located at the inboard of break, two breaks all pass through the two ends of the hinged drag link of drive link, also are connected with the vertical pulling lever arm on the break.Directly adopt brake disc in wheel hub, under the identical situation of output braking moment, its size and quality are all less like this, are easier to realize that the gap adjusts automatically.Brake disc can play braking action to wheel hub under the effect of friction plate.Air chamber can produce air pressure, makes break can produce braking force.Break is 19.5 inches breaks, goes for general middle bus.The utility model is for caliper disc brake in addition, because brake disc exposes, and the good advantage of dispelling the heat in addition.
As preferably, be provided with cylinder in the described air chamber, the push rod of cylinder is connected with Returnning spring.After the cylinder operation, can produce air pressure, thereby make disk type braker produce braking force, thereby form the effect of brake.
As preferably, the housing of described wheel hub is provided with friction plate limiting wear indicator, friction plate limiting wear indicator contact brake disc.After the friction plate excessive wear, friction plate limiting wear indicator does not reach the friction plate on the brake disc, gives control system thereby send signal, requires more renewal of facing renewal.
Therefore, the utility model does not have friction and helps the gesture effect, thereby brake efficiency is subjected to the influence of friction factor less, and promptly usefulness is more stable; Immersion back usefulness reduces less, and need only can recover normal through twice braking; Under the identical situation of output braking moment, size and fair less; Brake disc is minimum along the thermal expansion amount of thickness direction, can not resemble brake clearance obviously to be increased the thermal expansion of brake drum and cause brake-pedal travel excessive; Be easier to realize that the gap adjusts automatically, other maintenance reconditioning works are also easier, simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is plan structure schematic representation of Fig. 1.
Component, position and numbering among the figure: front axle 1, break 2, brake disc 3, wheel hub 4, air chamber 5, drag link 6, vertical pulling lever arm 7.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of automobile front axle disk type braker of this example, as Fig. 1, Fig. 2, a front axle 1 is arranged, the front axle two ends respectively are provided with break 2, and break 2 is 19.5 inches breaks.The outside of two breaks all is provided with brake disc 3, and the wheel rim mounting distance is 2280mm.The brake disc internal fixation has wheel hub 4, is connected with air chamber 5 on the wheel hub, and air chamber is located at the inboard of break, is provided with cylinder in the air chamber, and the push rod of cylinder is connected with Returnning spring.The housing of wheel hub is provided with friction plate limiting wear indicator, friction plate limiting wear indicator contact brake disc 3.Two breaks all pass through the two ends of the hinged drag link 6 of drive link, also are connected with vertical pulling lever arm 7 on the break.
During use, air chamber 5 produces air pressure, makes brake disc 3 produce braking effects, thereby whole wheel hub is braked, and automobile can be realized the function of braking.
The above only is a specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and variation of being done or modification all are encompassed among the claim of the present utility model.
