Abstract
An automobile braking montant for anti-brake shoe partial wear, relates to brake shoe attaching parts in a kind of self-propelled vehicle, solves the severe problem that affects driving safety of brake shoe partial wear.Comprise montant body, described montant body is divided into fixed end, middle part coupling end and lower fixed end from top to bottom, and upper fixed end is provided with fixed orifice, and lower fixed end is provided with lower fixed hole, upper fixed orifice and lower fixed hole are radially positioned at same level, and the axis in two holes is parallel to each other; The midway location of middle part coupling end is provided with the hole of revoking of fixing brake head, revokes the axis in hole and the axis of upper fixed orifice and lower fixed hole has angle, and angle is that 3.8 degree-5.7 are spent.The utility model make brake shoe after installation compared with prototype realization angle change; make the long-pending increase of brake shoe and flange tread curve contact surface; fall the one-sided state change center of putting forth effort of brake shoe puts forth effort simultaneously; eliminate brake shoe partial wear; make brake shoe integral body stressed; avoid occurring brake shoe local shedding after eccentric wear, poor stop crisis traffic safety.
Description
Technical field
the utility model relates to brake shoe attaching parts, specifically a kind of automobile braking montant of anti-brake shoe partial wear in a kind of self-propelled vehicle.
Background technology
as shown in Figure 1, the development of transporting along with enterprise railway at present, diesel locomotive is as the main traction power of current rail transportation, when hauling operation, due to enterprise's operation particularity, haul distance is short, have bad luck many, to constantly organize into groups, connect and hang, anti-hook, have bad luck, locomotive brake is extremely frequent, cause locomotive brake shoe abrasion abnormal, design structure due to former railcar brake beam causes brake shoe when contacting with flange tread curve simultaneously, there is one-side contact, cause eccentric wear, not only brake shoe consumption is large, also can cause friction material fracture because of brake shoe partial wear simultaneously, come off, reduce locomotive brake force, crisis traffic safety, so need to invent a kind of anti-eccentric wearing device, eliminate the manpower causing after eccentric wear, material resources cost increases, avoid train operation accident to occur.
Utility model content
the purpose of this utility model is to provide a kind of automobile braking montant of anti-brake shoe partial wear, the problem of solution.
the utility model solves the technical scheme that its technical matters adopts: a kind of automobile braking montant of anti-brake shoe partial wear, comprise montant body, it is characterized in that, described montant body is divided into fixed end, middle part coupling end and lower fixed end from top to bottom, upper fixed end is provided with fixed orifice, lower fixed end is provided with lower fixed hole, and upper fixed orifice and lower fixed hole are radially positioned at same level, and the axis in two holes is parallel to each other; The midway location of middle part coupling end is provided with the hole of revoking of fixing brake head, revokes the axis in hole and the axis of upper fixed orifice and lower fixed hole has angle, and angle is that 3.8 degree-5.7 are spent.
the angle of revoking the axis in hole and the axis of upper fixed orifice and lower fixed hole is 4.8 degree.
middle part coupling end and upper fixed end and lower fixed end adopt welding.
the beneficial effects of the utility model are: to montant middle part, suspension rod pin-and-hole place carries out structural change; make middle part revoke 4.8 ° of hole corners; make brake shoe after installation compared with prototype realization angle change; make the long-pending increase of brake shoe and flange tread curve contact surface; fall the one-sided state change center of putting forth effort of brake shoe simultaneously and put forth effort, eliminate brake shoe partial wear, make brake shoe integral body stressed; avoid occurring brake shoe local shedding after eccentric wear, poor stop crisis traffic safety.
Accompanying drawing explanation
fig. 1 is the scheme of installation of montant,
fig. 2 is structural representation of the present utility model,
fig. 3 is the A-A view of Fig. 2,
fig. 4 is brake clearance comparison diagram after adjusting.
in figure: 1 montant body, fixed end on 2,3 middle part coupling ends, 4 times fixed ends, fixed orifice on 5,6 lower fixed holes, 7 revoke hole.
The specific embodiment
as Fig. 2, Fig. 3, shown in Fig. 4, a kind of automobile braking montant of anti-brake shoe partial wear, comprises montant body 1, described montant body is divided into fixed end 2, middle part coupling end 3 and lower fixed end 4 from top to bottom, middle part coupling end 3 adopts welding with upper fixed end 2 and lower fixed end 4, and upper fixed end 2 is provided with fixed orifice 5, and lower fixed end 4 is provided with lower fixed hole 6, upper fixed orifice 5 and lower fixed hole 6 are radially positioned at same level, and the axis in two holes is parallel to each other; What the midway location of middle part coupling end 3 was provided with fixing brake head revokes hole 7, revokes the axis in hole 7 and the axis of upper fixed orifice 5 and lower fixed hole 6 has angle, and angle is that 3.8 degree-5.7 are spent.
preferred plan, the angle of revoking the axis in hole and the axis of upper fixed orifice and lower fixed hole is 4.8 degree.
combustion engine brake shoe partial wear reason mainly contains some:
from brake shoe suspension rod to brake head and each parts clearance of brake shoe pin excessive, cause the amount of swinging larger.
2. analysis from designing, brake head does not have certain fixed form, and (steam locomotive brake equipment/brake head is fixed as one with the swollen rod of braking, and brake when stressed, left and right sides brake head produces pulling force to the inside by braking swollen rod, while having eliminated vehicle wheel rotation, tread gradient is outwards caught up with the pulling force of brake shoe.
3. during locomotive brake, it is stressed that tire tread can not produce straight line front, due to tread gradient, brake shoe occurs that the stressed galling in inner side is large, and the stressed little wearing and tearing in outside are little, occurs that brake shoe inner side is to limit, outside abrasion loss is very little, and not only cost of idleness, seriously puts and affected locomotive brake force.
brake shoe skew certain angle can form joining place with wheel rim, and therefore according to flange tread curve state, deviation angle is made as θ, simulation θ slope be 1:10,1:15 the corner size at this place be:
arctg (1/10)=5.7 degree
arctg (1/15)=3.8 degree
getting its intermediate value is 4.8 degree
revoking a side-play amount sets:
brake head center pin place width is 14cm, and the side-play amount at this place is 14 * sin θ
14×sin5.7＝1.398cm
14×sin3.8＝0.931cm
14×sin4.8＝1.17cm
by above theoretical calculating, and carried out 3 kinds of size remodeling, through the wear test repeatedly of 6 months, result showed that the wear resistance ratio of 4.8 degree remodeling is more even, is optimized migration angle.
