Technical solution of the present invention has the advantages that
1. the brake lining provided by the invention for preventing eccentric wear, is set on brake plate support, it is provided with longitudinal rod on the brake plate support,
The brake lining includes: pad back plate, is mounted on the brake plate support；Friction component is set to the pad back plate far from described
The other side of brake plate support；The vertical range of the axis of the horizontal orthographic projection and longitudinal rod of the whole center of gravity of the friction component
For 0-8mm, and the axis of the horizontal orthographic projection and the longitudinal rod is located on same vertical plane.Since brake lining is set to lock
In piece support, longitudinal rod of the brake plate support by being set on brake plate support and the brake apparatus for driving brake plate support and brake lining to move
Brake lever connection, brake apparatus drives longitudinal rod to move by control brake lever movement, so drive brake plate support and
Brake lining movement, thus the axis of longitudinal rod become brake plate support by the line of force, since brake lining passes through friction component and brake disc
Friction, makes being located in the whole center of gravity of friction component by the line of force for brake lining, therefore said structure design can make the stress of brake lining
Line and brake plate support by the horizontal orthographic projection of the line of force close to being overlapped, to keep the stress of brake lining more uniform, be not likely to produce on the inside of by
Power is excessive, Innerside wear is serious or outside stress is excessive, outer wear serious situation, due in brake lining use process with abrasion
Friction material lowest point carries out abrasion and calculates progress brake lining replacement to limit afterwards, therefore outside uniform force avoids brake lining in brake lining
Replacement cycle caused by eccentric wear is short, and then can reduce operation cost；Such design can make brake lining rub with brake plate support simultaneously
It is more uniform to wipe the heat distribution generated, to make brake disc uniformity of temperature profile, brake disc is made to be not likely to produce fire check, thus
Extend the service life of brake disc.
