The bent straight pull rod arm is installed simply and tightly and is not easily loosened.
Description
Technical field
The invention belongs to the automobile front axle steering hardware, especially relate to a kind of vertical pulling lever arm of automobile front axle.
Technical background
Existing automobile is the propons drag link arm of autotruck especially, generally is straight-bar shape arm, and drag link is installed in perforate on arm, this vertical pulling lever arm, brachium and intensity are low, easy deformation, fracture, service life is short, and is also easily loosening after installing simultaneously, influences the safety of running car.
Summary of the invention
The objective of the invention is to propose a kind of automobile front axle bending vertical pulling lever arm with keyway, the intensity height, not yielding and fracture, long service life further improves running safety and economy.
The object of the present invention is achieved like this, a kind of automobile front axle bending vertical pulling lever arm with keyway, it is characterized in that: the automobile front axle bending vertical pulling lever arm of this band keyway (annotating: hereinafter to be referred as " bending vertical pulling lever arm ") is approximate L shaped, left side section is vertical underlying section, this left side section is followed successively by the cylinder external thread section from the bottom to top, rounding frustum section and transition phase, between this external thread section and the rounding frustum section is round-corner transition, the diameter of cylinder external thread section is less than the diameter of rounding frustum section small end, on the preceding left conical surface of rounding frustum section, offer axial rectangle keyway from small end, and the angle between the sagittal radial centre lines of the radial centre lines of this axial rectangle keyway and rounding frustum section is 25 °-35 °, this rounding frustum section is corresponding equipped with the taper mounting hole on the steering swivel with key, and the expense hole is with the construction opening pin on the section of the lower end of external thread section; The right section of this bending vertical pulling lever arm for front lower place to the right to the straight bar section of tiltedly stretching, between the right section of this bending vertical pulling lever arm and the left side section is the arc transition section, the right-hand member section of this bending vertical pulling lever arm is for being sagittal short cylindrical section, on this short cylindrical section, offer the pre-small post-large conical through-hole of diameter, be used for installing the automobile drag link.
During installation, earlier on the automobile front axle bending vertical pulling lever arm of this band keyway, square key is installed, again with in the taper mounting hole on the corresponding steering swivel of packing into of this bending vertical pulling lever arm left side section, keyway is packed this bending vertical pulling lever arm left side section into after to keyway, and on bending vertical pulling lever arm external thread section, install and tighten fluted nut, penetrate spring cotter again and fix, in the conical through-hole of the right section of bending vertical pulling lever arm of again bulb of steering drag link being packed into, install simply, and install closely difficult loosening.
The automobile front axle bending vertical pulling lever arm of band keyway proposed by the invention, intensity is good, and is not yielding, installs simply, and install closely difficult loosening.
Now in conjunction with the accompanying drawings and embodiments the automobile front axle bending vertical pulling lever arm of band keyway proposed by the invention is described further.
