Abstract
The utility model provides the track rod lever of a kind of long service life, not easy fracture.It comprises the ring set with taper hole, has the cutting ferrule of two parallel axis holes; Be connected to crank arm between ring set with cutting ferrule; The axis of two axis holes forms axis hole face, and ring set is positioned at side, axis hole face, and ring set axis is vertical with axis hole face; Distance A=2-4mm between the end face of the ring set one end at the large end place of taper hole and axis hole face.
Description
Technical field
The utility model relates to horizontal drawing lever for car steering arm, specifically, is a kind of heavy-duty truck propons track rod lever.
Background technology
Certain heavy-duty truck propons track rod lever, see shown in Fig. 1,2, comprises the ring set 1 with taper hole 11, has the cutting ferrule 2 of two parallel axis holes 21,22; 3 to be connected to crank arm between ring set with cutting ferrule.The axis of two axis holes forms axis hole face 23, and ring set is positioned at side, axis hole face, and ring set axis is vertical with axis hole face; Distance A=15mm between the end face 12 of the ring set one end at the large end place of taper hole and axis hole face.The spacing B=174-14mm of axis hole 21 axis that taper hole axis is nearest with it.In axis hole face, the spacing C=92-107mm of taper hole axis and cutting ferrule end face 24 far away.Through test, the material composition of this track rod lever (percentage composition of C, Si, Mn, S, P, Cr, Mo be respectively 0.39-0.44,0.17-0.37,0.60-0.90 ,≤0.025 ,≤0.025,1.0-1.25,0.16-0.25) meet the requirements, hardness (HB261-304), metallographic structure are all qualified, but in actual use, often there is crank phenomenon of rupture in this track rod lever.
Summary of the invention
The utility model object is to provide the track rod lever of a kind of long service life, not easy fracture.
Track rod lever described in the utility model, comprises the ring set with taper hole, has the cutting ferrule of two parallel axis holes; Be connected to crank arm between ring set with cutting ferrule; The axis of two axis holes forms axis hole face, and ring set is positioned at side, axis hole face, and ring set axis is vertical with axis hole face; Distance A=2-4mm between the end face of the ring set one end at the large end place of taper hole and axis hole face.Above-mentioned track rod lever, the spacing B=160-170mm of the axis hole axis that taper hole axis is nearest with it.
Above-mentioned track rod lever, is characterized in that: in axis hole face, the spacing C=90-95mm of taper hole axis and cutting ferrule end face far away.
The beneficial effects of the utility model: the utility model have modified drop A, B, C between ring set and cutting ferrule, especially the distance A between the end face of the ring set one end at the large end place of taper hole and axis hole face is reduced, eliminate stress concentration phenomenon of cranking arm, improve the anti-fatigue ability of track rod lever, effectively prevent the fracture of cranking arm.
Accompanying drawing explanation
Fig. 1 is existing track rod lever front view;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is track rod lever front view of the present utility model;
Fig. 4 is the left view of Fig. 3.
Detailed description of the invention
See the track rod lever shown in Fig. 3,4, comprise the ring set 1 with taper hole 11, there is the cutting ferrule 2 of two parallel axis holes 21,22; 3 to be connected to crank arm between ring set with cutting ferrule.The axis of two axis holes forms axis hole face 23, and ring set is positioned at side, axis hole face, and ring set axis is vertical with axis hole face; Distance A=3mm between the end face 12 of the ring set one end at the large end place of taper hole and axis hole face.The spacing B=165mm of axis hole 21 axis that taper hole axis is nearest with it.In axis hole face, the spacing C=92mm of taper hole axis and cutting ferrule end face 24 far away.Its material, hardness, metallographic structure etc. are same as the prior art.
To track rod lever of the present utility model and existing track rod lever modeling, carry out stress analysis, can find, concentration phenomenon that track rod lever of the present utility model is substantially unstressed, but existing track rod lever stress concentration phenomenon is serious.
