Old-fashioned sheave needs to be welded in the traction crossbeam and traction seat vertical pole of semitrailer simultaneously, traction crossbeam with lead
Introduction vertical pole is welded into intersecting parallels and then is welded on semi-trailer longitudinal beam, and the presence of traction crossbeam and traction seat vertical pole increases very big
Weight, and in order to keep sheave indeformable, sheave can constantly thicken as the load increases, this also will increase additional weight
Amount.Old-fashioned sheave is to be welded to connect, non-dismountable.
Utility model content
In view of the deficiencies of the prior art, the technical issues of the utility model intends to solve is to provide a kind of High-strength light-weight
Semitrailer sheave.
The technical solution that the utility model solves the technical problem is to provide a kind of High-strength light-weight semitrailer traction
Disk, it is characterised in that the sheave includes top plate, stiffening plate, bottom plate, the first seamless steel pipe, ring flange, towing pin, second seamless
Steel pipe and vertical plate；
The two sides of the top plate are connected with the two sides that bottom plate is handled through bending；The center of top plate is provided with a central through hole
For placing the second seamless steel pipe, the uniformly distributed through-hole of several annulars is provided with for placing the first seamless steel around this central through hole
Pipe；First seamless steel pipe is connect with top plate and bottom plate respectively；Two pieces of vertical plates are connected to other two upper lateral part of bottom plate
With other two side lower part of top plate；Several stiffening plates are connected on vertical plate, top plate and bottom plate；Bottom plate center is provided with a center
Through-hole；The bottom surface of ring flange is connected to bottom plate top；Second seamless steel pipe is connect with top plate and ring flange respectively；It is described to lead
Draw pin to connect with ring flange；Mounting of roof plate has the two sides of vertical plate to be provided with connecting hole, connect for the stringer with semitrailer；Top plate is opened
There are several first through hole, for realizing lightweight.
Compared with prior art, the utility model beneficial effect is:
1, allowable load is big, and reduce stress and concentrate: this sheave is made of top plate and bottom plate two-layered steel plates, and centre is by difference
Seamless steel pipe, vertical plate and the stiffening plate of size are attached, and form box like structure, which makes sheave integrally bear to lead
Gravitation, and then reduce stress and concentrate, increase allowable load, improves whole safety coefficient.
Traction disk center connect by the second seamless steel pipe, connects top plate thereon, lower acting flange disk, ring flange and with bottom plate phase
Even, to realize that the power for carrying out towing pin transmitting is distributed on entire sheave by center, keep sheave relatively reliable durable.
Sheave using the first seamless steel pipe around traction disk center carry out annular spread, this construction reduces work when
Concentrated stress.
2, structure lightened: to carry out punching de-material in the rational position of top plate and bottom plate after topological optimization, do not influencing
Weight is alleviated in the case where overall stiffness.And this sheave does not need traction crossbeam and traction seat vertical pole, need to only pass through spiral shell
The connecting hole of top plate two sides is connect by bolt with semi-trailer longitudinal beam, more alleviates weight.
3. dismoutability: this sheave is connected by bolt with semi-trailer longitudinal beam, convenient for disassembly and assembly, reduces maintenance cost.
4. base plate size is less than top plate, lightweight is not only realized, guaranteed by structure design in sheave and traction saddle
When producing relative rotation, bottom plate will not cause to scratch to traction saddle.
