Abstract
The invention discloses a floating braking mechanism. The floating braking mechanism is used in a brake clamp and can achieve braking in cooperation with a brake block on a brake disc. The floating braking mechanism is characterized by comprising a piston and a sealing ring; the piston is located in a piston hole of the brake clamp; the piston comprises a piston body and a piston head; the piston body is located in the brake clamp; steel balls are arranged outside the piston body; the steel balls are connected with the piston head in a matched mode, so that a floating piston structure is formed, and universal floating cooperation can be achieved through the brake block and the floating piston structure; and the piston body is sleeved with the sealing ring, and the sealing ring is located in the piston hole of the brake clamp, so that a sealing structure between the brake clamp and the piston body is formed. By the adoption of the floating braking mechanism, self-adjustment of the piston can be achieved, the effect that the brake block is in surface-surface fit with the brake disc is guaranteed, the braking effect is better, and the service life of the brake block is prolonged; and due to the fact that the brake block is in surface-surface fit with the brake disc, the force applying area is enlarged, the situation that the piston body inclines due to the change of the piston head is avoided, and the service life of the sealing ring is prolonged.
Description
Technical field
The present invention relates to a kind of floating brake mechanism, divide by International Patent Classification (IPC) (IPC) and belong to brake of motor-driven vehicle technical field。
Background technology
Its operation principle of existing braking clamp is in the space that brake fluid injects vice body and piston, promotes piston, promotes that brake block is two-way holds brake disc tightly simultaneously, makes wheel stop operating。This type of braking clamp uses very wide in engineering machinery。
But when braking clamp is installed incorrect, as not parallel in brake block and brake disc, when so starting brake, brake block stress is big, can against brake disc, and piston will be not that face coordinates with face with coordinating of brake block, but point coordinates。Therefore piston can be adjusted by the reserved fit clearance oneself of sealing ring with piston hole, but after so activity is of a specified duration, ring wear is serious, can produce oil leakage phenomenon。If brake weight is adjacent to brake disc completely insufficient for brake block, that so can cause brake block by an abrasion slowly to surface wear, reduces the service life of brake block, and disc surface tilts being。
Thus, it is considered as desirable by the inventor to the braking mechanism of braking clamp is improved, this case thus produces。
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of floating brake mechanism, it is possible to achieve piston self regulation, it is ensured that brake block is all that face coordinates with brake disc with face, braking effect is better, extends the service life of brake block；Piston head is that face contacts with face with brake block, increases force area, and piston body will not be subject to piston head change and produce, and extends the service life of sealing ring。
For reaching above-mentioned purpose, the present invention is achieved by the following technical solutions:
A kind of floating brake mechanism, it coordinates realization to brake in braking clamp and with the brake block on brake disc, this braking mechanism piston and sealing ring, wherein:
Piston, it is positioned at the piston hole of braking clamp, and this piston includes piston body and piston head, described piston body is positioned at braking clamp, it is provided with steel ball outside piston body, and this steel ball and piston head are connected, formed and can realize the floating piston framework that universal floating coordinates with brake block；
Sealing ring, its sheathed with piston body on and be positioned at the piston hole of braking clamp, form the sealing framework between braking clamp and piston body。
Further, described steel ball is wrapped in universal locating slot, and the arc groove that this universal locating slot is piston body and piston head relative position is offered cooperatively forms。
Further, between described piston head and piston body, it is provided with guard ring, thus forming the protection structure that piston head is connected with piston body。
Further, described sealing ring is embedded in the groove of braking clamp piston hole inwall, and coordinates with piston body sidewall, forms the sealing structure between piston body and braking clamp。
Further, described groove is seal groove, and this seal groove designs for lower inclined plane。
Further, it is provided with dust ring between described piston head and braking clamp, and this dust ring is fixed by collar, thus forming dust-proof framework。
Compared with prior art, advantages of the present invention:
1, the present invention realizes coordinating by steel ball by piston body, piston head, on piston body swingable, form the floating piston assembly of a universal adjustment formula, and then brake block and piston head coordinate the mated condition that can reach complete face with face, piston body will not be subject to the impact of external force and cause tilting, so extending again the service life of sealing ring；
2, heretofore described seal groove is the design of lower inclined plane, can make bottom graceful oil crush seal circle so that sealing ring expands and closely cooperates with piston body；
3, the present invention entangles piston head and braking clamp by dust ring, and utilizes collar to fix, and then effective minimizing extraneous earth, the dust impact on piston；
4, in the present invention, steel ball is wrapped, and forms package structure, makes product be easily installed, positions；
5, the increase of heretofore described guard ring, effectively ensures the monolithic devices in transfer transportation；
6, present invention achieves the function of " outer anti-interior crowded middle correcting ", improve the reliability of braking clamp, increase service life, and easy to maintenance。
