Abstract
The utility model discloses a steering plumbing arm of double front axle connecting underneath type interlocking draw rod, which comprises a bar, wherein the upper end of the bar is provided with a rocker shaft center hole, the middle portion of the bar is provided with a first straight draw rod fixing hole, and the lower end of the bar is provided with a second straight draw rod fixing hole, and the distance between the center of the second straight draw rod fixing hole and the center of the rocker shaft center hole is L1, and the distance between the center of the first straight draw rod fixing hole and the rocker shaft center hole is L2. The rocker shaft center hole is arranged on the upper portion of the bar by the steering plumbing arm, and two straight draw rod fixing holes are both arranged under the rocker shaft center hole, and downward arrangement of the interlocking draw rod is achieved, space limitation is reduced when the interlocking draw rod is upwards arranged, and a double front axle steering mechanism which is arranged in a long-head heavy-duty dump truck is achieved, the length of the bar holes of the whole bar is L1, and the length of the steering plumbing arm is shortened, and materials and space can be saved.
Description
Technical field
The utility model belongs to the automotive steering structure parts, is specifically related to the steering drop arm that a kind of connection turns to linkage pull rod.
Background technology
The structure of the steering drop arm of existing two propons connection linkage pull rods as shown in Figure 1, it is that fixed orifice with steering drag link is arranged on the two ends at the pitman arm center, the two ends that are rod member are the first drag link fixed orifice and the second drag link fixed orifice, the rod member middle part is the rocker shaft centre hole, the first drag link fixed orifice is L1 to the distance of rocker shaft centre hole, the second drag link fixed orifice is L2 to the distance of rocker shaft centre hole, and the length between the rod member hole is L1+L2.The structure of this steering drop arm makes linkage pull rod be arranged on the rocker shaft center, is restricted on the linkage pull rod arrangement space, and particularly this structure can not be arranged on the long engineering dump truck of two propons of high-power; Simultaneously, steering drop arm length is longer, and materials are many, the cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of steering drop arm that two propons connect the underneath type linkage pull rod that is suitable for, to address the above problem.
The technical solution of the utility model is: two propons connect the steering drop arm of underneath type linkage pull rod, and it comprises rod member, and the rod member upper end is provided with the rocker shaft centre hole, and the first drag link fixed orifice is established at the rod member middle part, and the second drag link fixed orifice is established in the rod member lower end; The second drag link fixed orifice center is L1 to the distance at rocker shaft centre hole center; The center of the first drag link fixed orifice is L2 to the distance at rocker shaft centre hole center.
This steering drop arm is arranged on the top of rod member with the rocker shaft centre hole, and two drag link fixed orifices all are located under the rocker shaft centre hole, realizes the downward layout of linkage pull rod, reduces the limited space when putting on the linkage pull rod; Can in long nose heave type dumping car, realize the production of two Front Axle Steering Mechanism, and then can realize the production of 8 * 4 long nose heave type dumping cars, remedy the deficiency of existing product series; Simultaneously, the second drag link fixed orifice center is L1 to the distance at rocker shaft centre hole center, and the length between the rod member hole of whole rod member is L1, has shortened steering drop arm length, can save the material and the space of L1-L2 length, and not influence the design proportion L1/L2 of steering hardware.
Description of drawings
The original steering drop arm structural representation of Fig. 1.
The steering drop arm master that the two propons of Fig. 2 connect the underneath type linkage pull rod looks scheme drawing.
The two propons of Fig. 3 connect the steering drop arm schematic side view of underneath type linkage pull rod.
The specific embodiment
Present embodiment is used for the explanation to this claim; protection domain of the present utility model is not limited to down the description of array structure, and those skilled in the art all is protection domains of the present utility model according to the indicative and indicative structure of doing that is different from present embodiment of the technical scheme that this claim 1 proposes.
Steering drop arm comprises rod member 1, and the shape of rod member 1 can design according to concrete vehicle, and the shape of rod member 1 of the present utility model as shown in Figure 3.Rod member 1 structure as shown in Figure 2, rocker shaft centre hole 2 is located at rod member upper end, the first drag link fixed orifice 3 is established at rod member 1 middle part, the second drag link fixed orifice 4 is established in rod member 1 lower end; Rocker shaft center hole wall is provided with locking slot 5, offers locking screw keyhole 6 (Fig. 2) on the locking slot cell wall.The second drag link fixed orifice center is L1 to the distance at rocker shaft centre hole center; The center of the first drag link fixed orifice is L2 to the distance at rocker shaft centre hole center.The design proportion L1/L2 of steering hardware is identical with traditional design proportion, but length is L1 between the length hole of rod member 1.
Claims (2)
1, the steering drop arm of a kind of pair of propons connection underneath type linkage pull rod, it comprises rod member, it is characterized in that the rod member upper end is provided with the rocker shaft centre hole, and the first drag link fixed orifice is established at the rod member middle part, and the second drag link fixed orifice is established in the rod member lower end; The second drag link fixed orifice center is L1 to the distance at rocker shaft centre hole center; The center of the first drag link fixed orifice is L2 to the distance at rocker shaft centre hole center.
