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 power hydraulic pressure brake field, specifically the multi-faceted automatic tracking apparatus of a kind of power hydraulic pressure Disk Brake tile fragment.
Background technique
Break is when normally closed, whether effectively brake torque is acted on brake disc, in many reasons, the brake rim of break brake shoe and the brake disc friction factor of area of contact and friction material in friction pair contact plane is very important two factors, the friction factor of friction material is setting value (having specialized factory to manufacture) when design so, therefore, area of contact seems particularly important.
At present, braking tile fragment has two kinds with the connecting mode of break main body: 1) with stud bolt, connect (braking tile fragment is without any relative movement), 2) with bearing pin, connect (braking tile fragment can rotate around bearing pin); Once brake disc Yu Qi center is while having perpendicularity morpheme error, brake disc to have end face run-out form error, the first structure is without any adjustment measure, and the second structure can only be around brake shoe rotating pin axle center rotating.
Summary of the invention
The object of this invention is to provide the multi-faceted automatic tracking apparatus of a kind of power hydraulic pressure Disk Brake tile fragment, the problem that cannot adjust existing in connecting with break main body to solve existing braking tile fragment when there is morpheme error shape error.
Technical solution of the present invention is as follows:
The multi-faceted automatic tracking apparatus of power hydraulic pressure Disk Brake tile fragment, comprises braking tile fragment, brake disc, on described braking tile fragment, is fixed with regulating element, in described regulating element, is provided with rotating pin, and described rotating pin peripheral hardware has joint shaft bearing.
As improvement of the present invention, the outer surface of described joint shaft bearing is spheroidal.
As a further improvement on the present invention, described braking tile fragment connects with regulating element by 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 invention will be further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of the multi-faceted automatic tracking apparatus of power hydraulic pressure Disk Brake tile fragment;
Fig. 2 is the side view of Fig. 1.
Embodiment
The multi-faceted automatic tracking apparatus of power hydraulic pressure Disk Brake 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 regulating element 3, and rotating pin 4 peripheral hardwares have joint shaft bearing 5.The outer surface of joint shaft bearing 5 is spheroidal.
In present embodiment, brake tile fragment 1 and connect with regulating element 3 by screw 2, regulating element plays controlling device axial position and fixation.
As shown in the figure, during break normally closed, the area of contact that the braking plane of braking tile fragment 1 and brake disc 6 is B should be 100%, once brake disc Yu Qi center is while having perpendicularity morpheme error, brake disc to have end face run-out form error, the joint shaft bearing 5 of this device is just brought into play it compared with property; In the structure of the Internal and external cycle of plain radial bearing, rotating part is spherical surface, and after outer ring is fixing, inner ring can rotate arbitrarily around X, Y, Z axis, and rotation angle minimum also can reach 6 °.During arrester close, maximal clearance A between brake rim and brake disc has 1.1mm, here pressing 1.5mm calculates, brake rim is when y, z axle rotate, rotation angle in the turning radius has respectively 2.5 ° of angles and 0.8 ° of angle, when x axle rotates, be subject to the restriction of break structural factor, the angle of swing in the turning radius has 0.8 °.And the minimum angle of swing of the GE series that joint radial bearing is selected at us all reaches 6 ° of angles.Can meet the demands completely.
