Abstract

The utility model discloses a single-piston type mechanical floating brake, which comprises a supporting frame, a braking embedded body which is arranged on the supporting frame, a lever mechanism, a braking push plate and a friction block assembly which is connected with the braking push plate. The single-piston type mechanical floating brake also comprises a one-way booster mechanism which is connected with the lever mechanism and the braking push plate, and the one-way booster mechanism comprises a torsion spring and a regulating sleeve. One end of the torsion spring is arranged on the regulating sleeve, and the other end is matched with a sleeve ring. The regulating sleeve is connected with the lever mechanism, and a sleeve ring gasket is arranged on the upper end of the sleeve ring and is tightly pressed by a compression spring. A rotating shaft is arranged in the sleeve ring, and a threaded push rod is arranged in the rotating shaft, wherein the bottom of the threaded push rod is provided with a rotation-stop pin. The technical schemes are used, which enables operating force for braking to be light. When a friction sheet is worn, the torsion spring has the function of storing spring force, which enables a gap between a friction block which is connected with the braking push plate and a wheel braking disk to be compensated.

Description

Single-piston Floating Mechanical Brake

Technical field

The utility model relates to automotive disc brake, is specifically related to single piston machine floating break.

Background technique

Existing automotive disc brake, it is that a slope member is set on the brake axle axle sleeve, advances by slope member roll extrusion steel ball propelling piston, adjusts push rod simultaneously and be the principle drive piston by the bolt and nut precession.It exists several major defects, and the one, manual operation is heavy, and the 2nd, along with the wearing and tearing of brake lining, need constantly to adjust push rod position, the 3rd, complex structure, poor stability.

Summary of the invention

The purpose of this utility model is to provide a kind of manual operation light, automatic friction compensation pad wear amount, single piston machine floating break of stable performance.

In order to solve the problems of the technologies described above, the utility model list piston machine floating break comprises support, is installed on the brake pad assembly that braking inlay, leverage, braking push pedal and braking push pedal on the support are connected, and it also comprises the unidirectional boosting mechanism that connects leverage and braking push pedal.

As further improvement of the utility model, described unidirectional boosting mechanism comprises torsion spring, adjust cover, described torsion spring one end is contained in to adjust and puts, and the other end cooperates with lasso, and described adjustment cover is connected with leverage, described lasso upper end is equipped with the lasso pad and is pressed by pressure spring, lasso inside is provided with rotating shaft, and described rotating shaft inside is provided with screw putter, and described screw putter bottom is provided with the spline pin.

The utility model is owing to adopt technique scheme, make that steering force is light when braking, and when friction disc wear, because the effect that torsion spring has storing spring power, impel with the braking brake pad that is connected of push pedal and the gap between wheel brake to be compensated, guaranteed the stability of product braking ability thus.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structural representation of the unidirectional boosting mechanism of the utility model.

Embodiment

As shown in Figure 1, the utility model list piston machine floating break comprises support 1, braking inlay 2, leverage 3, unidirectional boosting mechanism 4, braking push pedal 5 and brake pad assembly 6, braking inlay 2 is fixed on the support 1, leverage 3 links together with unidirectional boosting mechanism 4 by the bearing pin 31 of establishing its end, and unidirectional 4 terminal connections of boosting mechanism are braked push pedal 5, and braking push pedal 5 links together with brake pad assembly 6.

As shown in Figure 2, unidirectional boosting mechanism 4 comprises torsion spring 405, adjust cover 406, one end of torsion spring 405 is contained in to be adjusted on the cover 406, the other end cooperates with lasso 404, on adjustment cover 406, be provided with groove 40, the bearing pin 31 of leverage 3 is contained in this groove, be provided with the gap between bearing pin 31 and the groove 40, in lasso 404 upper ends lasso pad 403 is housed and presses by pressure spring 402, catch 401 is equipped with in pressure spring 402 upper ends, tightly is provided with rotating shaft 411 in lasso 404 inside, and this rotating shaft inside is provided with it with the screw putter 412 that is threaded, this screw putter bottom is provided with spline pin 413 and is fixed in the braking push pedal 5, rotating shaft 411 middle parts are contained on the supporting base 409 that places in the braking inlay 2, and its joint one side is equipped with axle jump ring 407 and volute spring 408, and opposite side is equipped with big pad 410.

When braking, external braking force top is to leverage 3, leverage 3 is when promoting supporting base 409 brakings, drive 406 rotations of adjustment cover through bearing pin 31, torsion spring 405 tightens up rotation, because the torsion spring the other end is contained on the lasso 304, lasso drives rotating shaft 411 rotations under the active force of torsion spring rotation and pressure spring 402 compressions like this, the screw putter 412 that is connected with rotating shaft 411 is advanced, thereby promote braking no good 5 and act on the brake pad assembly 5 that is attached thereto, wheel is braked.And when friction disc wear, because the effect that torsion spring has storing spring power, transmission by screw putter, braking push pedal, feasible brake pad that is connected with the braking push pedal and the gap between wheel brake are compensated, because friction disc wear how much, how many torsion springs just rotates, and writing down the wear extent of friction plate, and when removing air chamber pressure, torsion spring is just got back to a constant value and has been guaranteed the stable of product braking ability therefrom.
