Abstract
The utility model provides a dump truck frame in order to solve the problems of easy cracking of the welding part of a longitudinal beam and easy gravity shifting as the front end of the longitudinal beam of the heavy-duty truck frame adopts the digging and mending structure in the prior art. The dump truck frame comprises a right longitudinal beam assembly, a left longitudinal beam assembly, a front cross beam, a middle cross beam, a balance shaft cross beam, a tail cross beam and an auxiliary plate, wherein the longitudinal beam is a structure in which the height of the front part is equal to that of the rear part; the longitudinal beam assemblies, the cross beams and the auxiliary plate are connected by bolts or rivets; and the total width of the frame is 865+/-3mm. The dump truck frame has the beneficial technical effects that the digging and mending structure at the front end of the frame of the heavy-duty truck in the prior art is eliminated, thereby avoiding the cracking possibility of the welding part of the longitudinal beam of the frame. In addition, the width of the frame is increased, so that the stability of the whole truck is improved, and the rollover of the whole truck is effectively avoided.
Description
Invention field
The utility model relates to the heavy motor vehicle vehicle frame, specially refers to the dumping car vehicle frame.
Background technology
The heavy motor vehicle vehicle frame is the carrier that is connected other assembly and parts as the matrix of car load with main stressed member, in use not only to bear various devices, also to bear from the various load inside and outside the car, and the impact load of the complexity that causes because of road is concavo-convex.Prior art heavy goods vehicles vehicle frame mainly is made up of two vertical (lining) beams and several crossbeam, mainly considers bending strength and torsional strength during design, and moment of deflection is mainly born by longeron, and twist moment is mainly born by longeron and crossbeam.The longeron front end of prior art heavy motor vehicle vehicle frame has adopted the structure of mending by replacing a damaged part, ftractures easily at the position of chassis side rail welding, has influenced the service life of car load.In addition, the outer wide of prior art heavy motor vehicle vehicle frame is 780mm only, makes center of gravity easily be offset, and causes the stability of car load not enough, rollover easily.
Summary of the invention
Adopted the structure of mending by replacing a damaged part for overcoming prior art heavy motor vehicle chassis side rail front end, at the position of longeron welding the easy problem such as skew of cracking and center of gravity easily, the utility model proposes a kind of dumping car vehicle frame.The utility model dumping car vehicle frame comprises: right vertical beam assembly, left longeron assembly, front cross rail, intermediate transverse girder, balance shaft crossbeam, transom beam and subplate; Wherein, longeron is the contour structures in front and back; The longeron assembly adopts bolt or rivet to be connected with crossbeam and subplate; The vehicle frame overall width is 865 ± 3mm.
Further, wide before and after the utility model dumping car vehicle frame, front overhang length is 1100～1370mm, and wheelbase is 3220～4600mm, and rear overhang length is 870～1200mm, and vehicle frame aerofoil width is 75～85mm.
Further, the longeron assembly of the utility model dumping car vehicle frame is the contour structures in front and back; Comprise: longeron and lining beam, and adopt bolt or rivet to connect longeron and lining beam.
Further, it is that 280～325mm, thickness are 7～10mm that the longeron of the utility model dumping car vehicle frame adopts section height, and yield strength is greater than the big beam slab of 400 MPa.
The useful technique effect of the utility model dumping car vehicle frame is to have cancelled the structure of mending by replacing a damaged part that prior art heavy motor vehicle vehicle frame front end adopts, and has avoided the possibility of chassis side rail weld cracking.In addition, owing to increased frame width, improved the stability of car load, actv. has been avoided the rollover of car load.
Description of drawings
Accompanying drawing 1 is the schematic three dimensional views of the utility model dumping car vehicle frame embodiment;
Accompanying drawing 2 is elevational schematic view of the utility model dumping car vehicle frame embodiment.
Below in conjunction with drawings and the specific embodiments the utility model dumping car vehicle frame is further described.
The specific embodiment
Accompanying drawing 2 is elevational schematic view of the utility model dumping car vehicle frame embodiment, and among the figure, 1 is left longeron assembly, and 4 is the right vertical beam assembly, and 5 is front cross rail, and 6 is intermediate transverse girder, and 7 is that balance shaft crossbeam, 8 is transom beam.As seen from the figure, wide before and after the utility model dumping car vehicle frame, the vehicle frame overall width is 865 ± 3mm, and front overhang length is 1100～1370mm, and wheelbase is 3220～4600mm, and rear overhang length is 870～1200mm, and vehicle frame aerofoil width is 75～85mm.
For guaranteeing the intensity and the rigidity of vehicle frame, the longeron assembly of the utility model dumping car vehicle frame is the contour structures in front and back, and every longeron assembly includes longeron and lining beam, and longeron adopts bolt or rivet to be connected with the lining beam; And it is that 280～325mm, thickness are 7～10mm that longeron adopts section height, and yield strength is greater than the big beam slab of 400 MPa.。So not only cancel original welding sticking patch, increased the intensity and the rigidity of vehicle frame, also avoided the failure conditions of vehicle frame cracking to take place.
Obviously,, cancelled the structure of mending by replacing a damaged part that prior art heavy motor vehicle vehicle frame front end adopts, avoided the possibility of chassis side rail weld cracking through after the above-mentioned improvement.In addition, owing to increased frame width, improved the stability of car load, actv. has been avoided the rollover of car load.
