Abstract
The utility model provides a strenghthened type combination tail boom, includes a plurality of roof beams bodies, two upper junction plates and two lower connecting plates, the cross -section of the roof beam body is the U type, and the roof beam is personally experienced sth. Part of the body and is included last pterygoid lamina, lower pterygoid lamina and connect the web of going up pterygoid lamina and lower pterygoid lamina, go up the pterygoid lamina and be equipped with the stiffening beam down between the pterygoid lamina, the upper junction plate is the L type, and the upper junction plate includes diaphragm and last vertical plate, two upper junction plate symmetries set up the both ends at the roof beam body, go up diaphragm and last pterygoid lamina fixed connection, the connecting plate is the L type down, diaphragm and lower vertical plate under lower connecting plate includes, two lower connecting plate symmetries set up the both ends at the roof beam body, lower diaphragm and lower pterygoid lamina fixed connection. This strenghthened type combination tail boom, combination tail boom overall stability has been strengthened in upper junction plate, the setting of connecting plate down, the thickness of stiffening beam and the welding mode of personally experiencing sth. Part of the body with the roof beam have reached and have drawn the strength requirement of hook when pulling, and setting up of leaf spring support installation hole site and leaf spring support pin hole position makes the support fixed more firm.
Description
Technical field
The utility model belongs to vehicle frame tail boom, is specifically related to a kind of reinforced combination tail boom for single back axle heavy duty engineering truck.
Background technology
Along with the production domesticization of German graceful engine, the single back axle self-unloading vehicle mating graceful engine is favored by market, mate graceful engine dumper power foot, load-carrying big.Not only undertake various devices mounted thereto and the weight of vehicle-mounted cargo due to vehicle frame, but also bear due to the impact in the uneven driving process brought of road, so the research to vehicle frame tail boom intensity is necessary.Existing vehicle frame tail boom can not bear the impact that in transportation, vehicle frame is caused by road bumps well, and fracture or deformation easily occurs in vehicle frame, have impact on integeral vehicle life；Meanwhile, because frame distortion causes back axle, negative understeer have impact on whole vehicle stability.Temperature for vehicle frame tail boom intensity needs solution badly above.
Utility model content
The purpose of this utility model is for designing a kind of reinforced combination tail boom, with the requirement to vehicle frame tail boom intensity of the satisfied single back axle heavy duty engineering truck.
The technical solution of the utility model is: a kind of reinforced combination tail boom, and including multiple beam body, two upper junction plates and two lower connecting plates, the setting of connecting plate adds the stability of combination tail boom；The cross section of described beam body is U-shaped, and beam body includes the web of upper flange, lower wing plate and connection upper flange and lower wing plate, is provided with reinforcing plate between described upper flange and lower wing plate；Described upper junction plate is L-type, and upper junction plate includes upper cross plate and upper stringer board, and said two upper junction plate is symmetricly set on the two ends of beam body, and described upper cross plate is fixing with upper flange to be connected；Described lower connecting plate is L-type, and lower connecting plate includes lower cross plate and lower stringer board, and said two lower connecting plate is symmetricly set on the two ends of beam body, and described lower cross plate is fixing with lower wing plate to be connected.
Described upper cross plate rivets with upper flange, and described lower cross plate rivets with lower wing plate.
The thickness of described reinforcing plate is 8-12mm.This thickness range of reinforcing plate disclosure satisfy that strength and stiffness demand when rear towing hook pulls.
Described reinforcing plate is by being welded and fixed with beam body the form of fillet welding, and this connected mode ensure that the draw hook requirement of strength when towing.
Described upper stringer board and lower stringer board are provided with flat spring bracket mounting hole site.
Described lower stringer board is provided with flat spring bracket pin mounting hole site, and flat spring bracket pinhole position can make fixing more firm of flat spring bracket, more can meet the leaf spring requirement of strength to vehicle frame.
The beneficial effects of the utility model are: a kind of reinforced combination tail boom, upper junction plate, the connection of lower connecting plate, strengthen resistance to overturning and the rigid requirements of combination tail boom；The thickness of its reinforcing plate and the welding manner with beam body, reached the draw hook requirement of strength when towing, and the setting of flat spring bracket mounting hole site and flat spring bracket pinhole position makes fixing more firm of support, has reached to strengthen the effect of tail boom intensity.This combination tail beam structure is simple, practical, is suitable for popularization and application.
