Abstract
The utility model relates to a braking mechanism for an automobile, belonging to the field of the manufacture of the braking assembly of the automobile, and comprising a braking branch pump. A wheel hub is arranged at the lower part of a half-axle cannula via a bearing; an oil seal ring is positioned in the space composed of the wheel boss and the external diameter of the half-axle cannula; an external braking hub is connected with the wheel hub via a tyre bolt; a braking sleeve is sheathed on an internal braking disc which is connected with the half-axle cannula via a spline; the internal braking can slip axially; a back braking disc is connected with the internal braking disc via a reset spring; the upper end of the back braking disc of the utility model is fixedly connected to the half-axle cannula. The utility model has the advantages of peculiar and simple structural design, stable and reliable braking performance, convenient adjustment and easy control, and otherwise, the frictional surface of the braking hub (disc) is uneasy to be pulled with slots or abraded.
Description
The utility model belongs to the braking automobile assembly and makes the field.
Background technology of the present utility model: be on existing general-duty automobile braking device (brake equipment) structure two kinds of disc type or hub formulas (a lot of domestic and imported roadlices all generally adopt shroud after hub formula), all there are a common deficiency in disc type or hub formula, in use brake disc (hub) attrition surface pulls into groove and mistake garden or eccentric wear easily, cause brake failure, or basic not brake, because of drawing male and female face behind the ditch in vehicle ', because the wearing and tearing of part, or the Relative Zero parts produce displacement in servicing operations, pull down again dress multiple after, male and female face is difficult to coincide, and causes brake more ineffective.
Design goal of the present utility model: avoid weak point of the prior art, design a kind of novel structure, uniqueness, simple, braking effect is good and the braking automobile mechanism of adjustment easily.
Design plan of the present utility model: on the basis of existing braking automobile structure, a kind ofly have novel structure, uniqueness, simple, an effective braking automobile mechanism of drag by what the redesign to its brake band, interior brake disc, outer brake hubs, back brake disc and braking gap trimming screw etc. realized.Its organization plan: a kind of braking automobile mechanism, it comprises wheel cylinder (12), wheel hub (11) is installed in the bottom of axle tube (8) by bearing (6), oil seal washer (10) is positioned at wheel hub (11) and the outer space through constituting of axle tube (8), outer brake hubs (3) is connected with wheel hub (11) by tire bolt (9), brake band (1) is enclosed within on the interior brake disc (2), interior brake disc (2) is connected on the axle tube (8) by spline and can endwisely slips, back brake disc (5) links to each other with interior brake disc (2) by retracing spring (7), and the upper end of brake disc (5) and axle tube (8) are affixed thereafter.The attrition surface of outer brake hubs (3) is the conical surface, and its tapering and horizontal plane angle are 8 °～20 °, and the bonding plane of interior brake disc (2) is the conical surface, and the number of degrees of its tapering and outer brake hubs (3) and the angle of horizontal surface are identical, direction is opposite.Back brake disc (5) is split-type structural and adopts Bolt Connection.On back brake disc (5), braking gap trimming screw (4) is housed.When not braking, brake band (1) is free-running fit with the attrition surface of outer brake hubs (3).
The utility model is compared with background technology, and the one, structure design novelty, uniqueness, simple; The 2nd, drag is stable and reliable for performance; The 3rd, easy to adjust, easy grasp, brake hubs (dish) attrition surface are difficult in kerve, not easy to wear, the maintenance process not light requirement brake hubs and shoe plate, because the tapering attrition surface is progressive vertically, two conical surfaces have automatic guiding function.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the plan structure scheme drawing of Fig. 1.
1 and 2 pair of the utility model is done with narration in conjunction with the accompanying drawings.
A kind of braking automobile mechanism, it comprises that wheel cylinder (12) is installed in (Fig. 2 on the brake disc line of centers of back, belong to prior art), wheel hub (11) is installed in the bottom of axle tube (8) by bearing (6), oil seal washer (10) is positioned at wheel hub (11) and the outer space through constituting of axle tube (8), outer brake hubs (3) is connected with wheel hub (11) by tire bolt (9), brake band (1) is enclosed within interior brake disc (2) and goes up and cement, interior brake disc (2) is connected on the axle tube (8) by spline and can endwisely slips, back brake disc (5) links to each other with interior brake disc (2) by retracing spring (7), the upper end of brake disc (5) and axle tube (8) welding thereafter.The attrition surface of outer brake hubs (3) is the conical surface, its tapering and horizontal plane angle are 8 ° or 9 ° or 10 ° or 11 ° or 12 ° or 13 ° or 14 ° or 15 ° or 16 ° or 17 ° or 18 ° or 19 ° or 20 °, the bonding plane of interior brake disc (2) is the conical surface, and the number of degrees of its tapering and outer brake hubs (3) and the angle of horizontal surface are identical, direction is opposite.Back brake disc (5) is split-type structural and adopts Bolt Connection.On back brake disc (5), braking gap trimming screw (4) is housed.Its working process: when not braking, under the effect of retracing spring (7), brake band (1) is free-running fit with the attrition surface of outer brake hubs (3).During brake, the driver steps on brake pedal, master cylinder promotes two wheel cylinder (12) and produces axial propelling thrust simultaneously, promote brake disc (2) longitudinal travel in axle tube (8), compression reseting spring (7), the drive, make the brake band (1) that cements on the interior brake disc (2) produce the purpose that rubs braking force and reach drag with outer brake hubs (3).Other parts belong to prior art, are not described herein at this.
