Abstract
The invention discloses a multidirectional automatic following device for a brake shoe of an electric hydraulic disc brake, which solves the problem that an existing brake shoe connected with a brake body cannot be adjusted when position and shape errors occur. The multidirectional automatic following device comprises a brake shoe and a brake disc, an adjusting element is fixed onto the brake shoe, a rotary pin is arranged in the adjusting element, and a knuckle bearing is arranged outside the rotary pin. The multidirectional automatic following device is capable of automatically multi-directionally following positions of the brake disc so as to adjust the contact area of contact planes of a brake pad with a friction pair of the brake disc to reach a 100% ideal condition.
Description
Technical field
The invention belongs to the power hydraulic pressure brake field, the multi-faceted automatic following device of specifically a kind of power hydraulic pressure disk type braker braking tile fragment.
Background technique
Break is when normally closed; Whether effectively brake torque is acted on the brake disc; The brake rim of break brake shoe and the brake disc friction factor of area of contact and friction material in the friction pair contact plane is very important two factors in many reasons; The friction factor of friction material is setting value (having specialized factory to make) when design so, and therefore, it is particularly important that area of contact seems.
At present, the braking tile fragment has two kinds with the connecting mode of break main body: 1) connect (the braking tile fragment does not have any relative movement), 2 with stud bolt) connect (the braking tile fragment can rotate around bearing pin) with bearing pin; Once there is perpendicularity morpheme error at brake disc and its center, when brake disc has the end face run-out form error, first kind of structure do not have any adjustment measure, and second kind of structure can only be rotated around brake shoe rotating pin axle center.
Summary of the invention
The purpose of this invention is to provide the multi-faceted automatic following device of a kind of power hydraulic pressure disk type braker braking tile fragment, with the problem that when morpheme error form error occurring, can't adjust that exists in solving existing braking tile fragment and the break main body connecting.
Technological scheme of the present invention is following:
The multi-faceted automatic following device of a kind of power hydraulic pressure disk type braker braking tile fragment comprises braking tile fragment, brake disc, on said braking tile fragment, is fixed with regulating element, is provided with rotating pin in the said regulating element, and said rotating pin peripheral hardware has joint shaft bearing.
As improvement of the present invention, the outer surface of said joint shaft bearing is a spheroidal.
As further improvement of the present invention, said braking tile fragment connects with regulating element through screw.
The present invention carries out multi-faceted position of following brake disc automatically, thereby the area of contact of adjustment brake rim and brake disc friction pair contact plane makes it reach 100% perfect condition.
Below in conjunction with accompanying drawing the present invention is described further.
Description of drawings
Fig. 1 is the structural representation of the multi-faceted automatic following device of power hydraulic pressure disk type braker braking tile fragment;
Fig. 2 is the side view of Fig. 1.
Embodiment
The multi-faceted automatic following device of a kind of power hydraulic pressure disk type braker braking tile fragment comprises braking tile fragment 1, brake disc 6, on braking tile fragment 1, is fixed with regulating element 3, is provided with rotating pin 4 in the regulating element 3, and rotating pin 4 peripheral hardwares have joint shaft bearing 5.The outer surface of joint shaft bearing 5 is a spheroidal.
As shown in the figure; During the break normally closed; The braking plane of braking tile fragment 1 and brake disc 6 is that the area of contact of B should be 100%, once there is perpendicularity morpheme error at brake disc and its center, when brake disc has the end face run-out form error, the joint shaft bearing 5 of this device is just brought into play it than property; In the structure of the Internal and external cycle of plain radial bearing, rotating part is a spherical surface, and inner ring can rotate arbitrarily around X, Y, Z axle after the outer ring is fixing, and the rotation angle minimum also can reach 6 °.During arrester close; Maximal clearance A between brake rim and the brake disc has 1.1mm; Here press 1.5mm and calculate, brake rim is around y, the rotation of z axle the time, and the rotation angle in the turning radius has 2.5 ° of angles and 0.8 ° of angle respectively; When the x axle rotates, receive the restriction of break structural factor, the angle of swing in the turning radius has 0.8 °.And the joint radial bearing all reaches 6 ° of angles in the serial minimum angle of swing of GE that we select for use.Can meet the demands fully.
