Specific embodiment

The utility model is described further with reference to the accompanying drawing:

4 ~ 5 ton forklift of one kind as Figure 1-Figure 2 welding steeraxle structure 100, including pontic.The pontic includes Pontic main body is separately mounted to the front end-plate 103 and end plate 104 of front and rear sides among pontic main body, is separately mounted to pontic Two pairs of stub seats 108 of main body left and right ends；An articulated shaft 105 is mounted on the front end-plate 103 and end plate 104.Institute Articulated shaft 105 is stated, for being connected with forklift frame 300.It is separately installed with a pair of of stub seat in the left and right ends of pontic main body, often It include a stub seat for being mounted on upper bridge plate left or right and a stub for being mounted on lower bridge plate the same end to stub seat Seat.The stub seat for connecting with knuckle 200, and then carries out the connection of wheel.

Specifically, the pontic main body includes the upper bridge plate 101 and lower bridge plate 102 set gradually from up to down；It is described The first connecting rib 107 being sequentially connected, connection web 106 and the second dowel are equipped between upper bridge plate 101 and lower bridge plate 102 Plate 111；The left and right ends of the connection web 106 are weldingly connected with the first connecting rib 107, the second connecting rib 111 respectively. Oil cylinder mounting hole 1062 and oil pipe through-hole 1061 are offered on the connection web 106.First connecting rib 107 and second The outer end of connecting rib 111 offers an oblique c-type gap 110.The inner wall of the oblique c-type gap 110 includes being sequentially connected Upper slanted plane 1101, the first arc surface 1102, perpendicular 1103, the second arc surface 1104 and lower slanted plane 1105. The radius of first arc surface 1102 is not less than 50mm.Preferably, the inclination upwards of upper slanted plane 1101, inclination on this The angle of plane 1101 and horizontal plane is 7 degree；The lower slanted plane 1105 tilts down, the lower slanted plane 1105 and level The angle in face is 7 degree；The perpendicular is mutually perpendicular to horizontal plane；The radius of first arc surface 1102 is 80mm；The The radius of two arc surfaces is 30mm；The distance between central axis of the perpendicular and stub seat is 118mm；By to upper Clinoplain, the first arc surface, perpendicular, the second arc surface and lower slanted plane parameter be configured, can either guarantee The opening of oblique c-type gap is sufficiently large, avoids interfering with knuckle, and can guarantee the structural strength of pontic, this is avoided to slit Mouth is broken and influences the normal use of pontic.

Further, a blocky stress plate 109 is mounted at the top of the upper bridge plate of each 110 top of tiltedly c-type gap.Institute Stating blocky stress plate 109 is cuboid, and length is not less than 120mm, and width is not less than 50mm, and height (i.e. thickness) is not less than 15mm.The oblique c-type gap, for avoiding knuckle.By making the radius of the first arc surface not less than 50mm, and make bulk The thickness of stress plate is not less than 15mm, can guarantee the structural strength of pontic, and pontic is prevented to be broken in the opening position.

In conclusion the utility model is designed by the parameter of three arc surfaces to oblique c-type gap, and to bulk The structural parameters of the installation site of stress plate and blocky stress plate are designed, and can change two pieces of connecting rib upper curved surface knots The bending resistant section coefficient of structure, the stress for reducing partial structurtes at this are concentrated, and enhancing structure intensity, extend steeraxle uses the longevity Life.

Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this The various changes and improvements that the technical solution of utility model is made should all fall into the protection that the utility model claims book determines In range.
