Description
Technical field
The utility model is on bridge I-beam before a kind of heavy-load type.
Background technology
I-beam is the important load bearing component on automobile front axle, generally using forging molding, its both ends fist portion and front axle wheel
End connection, intermediate symmetry is equipped with spring carrying block, for being connected with leaf spring.
Presently used structural I-beam.The I-beam is all around symmetrical structure, both ends respectively have one before and after fist portion
Positive stop lug boss.
The structural I-beam bearing capacity of the prior art is poor, it is impossible to meets the requirement of heavy-load type engineering truck；I-shaped
Beam uses two level drop, and board support section and middle H-section are highly big, cause the vehicle road clearance small, and heavy-load type is certainly
Unload and generally used in building site, the problems such as road conditions are poor, and bridge I-beam bulldozes, collides with before this can cause；I-beam both ends fist portion with
Connection transition between I-beam axle journal uses larger R angles, causes fist portion intensity decreases；I-beam integrated stress is distributed not
, middle strong, both ends are weak, and local stiffness is larger, cause vehicle ride comfort and comfort poor.
Utility model content
The purpose of this utility model is to solve the problems, such as that I-beam bearing capacity is weak, poor rigidity, meets heavy-duty tipper
Requirement.
To realize above-mentioned technical purpose, the utility model provides bridge I-beam before a kind of heavy-load type, it includes：Positioned at middle part
Main part, positioned at the fist portion of both sides and connect the neck in the main part and the fist portion, wherein：The main part
Upper and lower surface it is parallel, and spring carrying block is installed in the main part, the cross-sectional width of the spring carrying block is more than institute
State the cross-sectional width of main part；The inclined arrangement of aperture outer wall at the fist portion；And the neck connects for flat level.
As a further improvement, the diameter of the upper end of the aperture outer wall at the fist portion is less than the diameter of its lower end.
As a further improvement, the cross section of the main part is in I-shaped, and the cross section of the main part
Top and the bottom have identical width.
As a further improvement, the cross section of the neck is rectangular.
The utility model is designed using level-one drop, reduces I-beam drop；Cancel two level drop, I-beam bottom Cheng Ping
Row posture, the road clearance of bridge before increasing, improves passability.

Reference numeral：Preceding bridge I-beam 1；Main part 11；Fist portion 12；Neck 13；Spring carrying block 14；Aperture outer wall 15.
Embodiment
As shown in Figures 1 to 6, the utility model provides bridge I-beam 1 before a kind of heavy-load type, it includes：Master positioned at middle part
Body portion 11, positioned at the fist portion 12 of both sides and connect the neck 13 in the main part 11 and the fist portion 12, wherein：The master
The upper and lower surface of body portion 11 is parallel, and spring carrying block 14 is provided with the main part 11, the spring carrying block 14
Cross-sectional width is more than the cross-sectional width of the main part 11；15 inclined arrangement of aperture outer wall at the fist portion 12；And institute
Neck 13 is stated to connect for flat level.
As a further improvement, the diameter of the upper end of the aperture outer wall 15 at the fist portion 12 is less than the straight of its lower end
Footpath.
As a further improvement, the cross section of the main part 11 is in I-shaped, and the main part is transversal
Face top and the bottom have identical width.
As a further improvement, the cross section of the neck 13 is rectangular.
The utility model is designed using level-one drop, reduces I-beam drop；Cancel two level drop, I-beam bottom Cheng Ping
Row posture, the road clearance of bridge before increasing, improves passability.
Easy to increase fist portion kingpin bore aperture, while fist cross section is non-constant section, and top is thin, following thick, i.e. upper end
Diameter be less than its lower end diameter, strengthen its stability and reliability；The neck of fist portion and I-beam link position uses flat
Straight structure, strengthens its torsional property.
The utility model is easy to design using iso-stress, and I-beam major section parameter is optimized, such as cross section A-A,
It shown in B-B, C-C, can solve the problems, such as that I-beam local stiffness is larger, improve vehicle ride comfort and comfort；I-shaped is increased to cut
Sectional dimension at face and leaf spring mounting base section, improves bearing capacity.
The utility model increases the bearing capacity and rigidity of I-beam, meets the requirement of heavy-duty tipper；Reduce
The drop of I-beam, improves vehicle passability, automobile is tackled more complicated driving cycle；Improve holding for fist portion
Loading capability and anti-torsion ability, meet the requirement when overload of fist portion and emergency braking；Designed by iso-stress, solve I-shaped
The problem of beam integrated stress skewness, local stiffness is larger, improve vehicle ride comfort and comfort；Used at fist portion kingpin bore
Up-thin-low-thick structure, improves the stability and reliability of I-shaped beam end.
It should be appreciated that the utility model scope of the claimed is not limited to non-limiting embodiments, it should be understood that non-limiting reality
Scheme is applied to illustrate as just example.The desired substantive protection domain of the application is more embodied in independent claims
The scope of offer, and its dependent claims.
