Currently used brake shoes is made up of bracing frame, back of the body steel and friction plate, and brake shoes is installed and gone up inside the shell, and back of the body steel is rotatably connected on shell, owing to being that I is rotationally connected, can gradually wear out in repeatedly use procedure, affect service life and braking effect.It addition, the opening and closing between two pieces of back of the body steel other ends control the displacement of friction plate, it is common that the rotation of the rotating shaft by being arranged on shell realizes, and can gradually wear out repeatedly stirring process shaft, affect service life and braking effect.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, and the present invention provides a kind of vehicle hub lock Special braking device.
This invention address that the technical scheme that its technical problem adopts is: a kind of vehicle hub lock Special braking device, stop block including shell and the ferrum that is arranged on shell, ferrum block of stopping includes bracing frame, back of the body steel and friction plate, friction plate is fitted on the lateral wall of back of the body steel, one end of bracing frame offers arc shape recess, back of the body steel is by carrying on the back steel body, first flanging and the second flanging composition, second flanging matches with the arc shape recess of bracing frame, first flanging matches with the other end of bracing frame, shell is provided with the locating dowel fixing the second flanging, the first lining it is provided with between locating dowel and the second flanging；
Shell between two the first flangings is rotatablely equipped with the rotating shaft being allocated to both sides, rotating shaft includes long oblate column rotating shaft body, symmetry is rotationally connected with two cylindrical rollers of rotating shaft body interior both sides and is installed on the basal surface cover plate by roller end seal of rotating shaft body, the inner surface of roller rolls with rotating shaft body and is connected, the outer surface exposing rotating shaft body of roller and the first flanging roll and connect, and are provided with the second lining between rotation axle and the shell of rotating shaft body.
Further, the first lining and the second lining are the sintered metal product with uniform hole, are impregnated with white oil in hole, and the first lining and the second lining material are cemented iron.
The invention has the beneficial effects as follows: the frictional resistance reduction that the lining being impregnated with white oil in hole makes shell and ferrum stop between block, is rotationally connected between locating dowel and the second flanging of back of the body steel；Being become rolling friction from sliding friction between first flanging of rotating shaft and back of the body steel, frictional resistance reduces, and abrasion reduces, and extends ferrum and stops life-span of block, improves braking effect.

Detailed description of the invention
Presently in connection with specific embodiment, the invention will be further described, and following example are intended to illustrate the present invention rather than limitation of the invention further.
A kind of vehicle hub lock Special braking device as shown in Figures 1 to 3, stop block including shell 4 and the ferrum that is arranged on shell, ferrum block of stopping includes bracing frame 1, back of the body steel 2 and friction plate 3, friction plate 3 is fitted on the lateral wall of back of the body steel 2, one end of bracing frame 1 offers arc shape recess, back of the body steel 2 is by back of the body steel body 21, first flanging 22 and the second flanging 23 form, second flanging 23 matches with the arc shape recess of bracing frame 1, first flanging 22 matches with the other end of bracing frame 1, shell is provided with the locating dowel 5 fixing the second flanging 23, it is provided with the first lining 6 between locating dowel 5 and the second flanging 23.
Shell 4 between two the first flangings 22 is rotatablely equipped with the rotating shaft being allocated to both sides, rotating shaft includes long oblate column rotating shaft body 7, symmetry is rotationally connected with two cylindrical rollers 8 of the internal both sides of rotating shaft body 7 and is installed on the basal surface cover plate 10 by roller 8 end seal of rotating shaft body 7, the inner surface of roller 8 rolls with rotating shaft body 7 and is connected, the outer surface exposing rotating shaft body 7 of roller 8 and the first flanging 22 roll and connect, and are provided with the second lining 9 between rotation axle and the shell 4 of rotating shaft body 7.Rotate, with the first flanging 22, the side surface of rotating shaft body 7 contacted curved, advantageously reduce rotating shaft body 7, friction between roller 8 and the first flanging 22.Roller 8 end is covered by cover plate 10, it is prevented that roller 8 comes off, and offers the rotation hole of erection roller 8 on cover plate 10 simultaneously, and roller 8 can be freely rotatable on cover plate 10.
