Abstract
The utility model discloses a car front axle pitman arm, including first connecting portion and second connecting portion, link to each other through the intermediate part between first connecting portion and the second connecting portion, the height of first connecting portion and the high sum of intermediate part and second connecting portion are equal be provided with steering gear spline fit hole on the first connecting portion still be equipped with on the second connecting portion to turning to bulb round pin mating holes, should turn to bulb round pin mating holes with steering gear spline fit hole is the conical bore, the central line and the central line that turns to bulb round pin mating holes in steering gear spline fit hole are parallel to each other steering gear spline fit hole all is equipped with the strengthening rib on the bulb round pin mating holes with turning to, the strengthening rib extends to the both ends in hole and forms the boss. It is showing the effect: be equipped with the strengthening rib, strengthened front axle pitman arm's intensity and performance, realize the reliable connection of round pin reel shaft among a steering system, effectively prevented the fracture of rocking arm.
Description
Technical field
This utility model is related to technical field of automobile parts, specifically, is a kind of automobile front axle pitman arm.
Background technology
Currently, domestic automobile suspension adapted turn to drive mechanism substantially using in the form of be mainly：Steering gear → steering is hung down
The arrangement of arm → steering linkage → pitman arm → left/right track rod.Wherein, pitman arm Main Function is that handle turns
Pass to track rod to the moment of device output and motion.Pitman arm is mostly important one of motor turning drive mechanism
Point, it is related to the accuracy of automobile steering system and whether the space arrangement of steering structure is reasonable.
However, the size of existing pitman arm and bellmouth no production standard, product quality that to ensure, in connection easily
Loosen, security reliability is poor；Secondly the steering linkage of steering is usually placed in a plane, and section is little, insufficient strength,
Pitman arm fracture often occurs and causes steering failure fault, thus causing the accident.
Content of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of automobile front axle pitman arm, Neng Goushi
Turn now in system being reliably connected of pin or axle, high mechanical strength, long service life, not easy fracture.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is as follows：
A kind of automobile front axle pitman arm, it is critical only that：Including first connecting portion and second connecting portion, described first even
It is connected by pars intermedia between socket part and second connecting portion, the height of described first connecting portion and pars intermedia and second connecting portion
Height sum is equal, is provided with steering gear spline fitted hole, also sets in described second connecting portion in described first connecting portion
Promising steering ball end pin mating holes, this steering ball end pin mating holes and described steering gear spline fitted hole are conical bore, described
The centrage in steering gear spline fitted hole is parallel to each other with the centrage of steering ball end pin mating holes, joins in described steering gear spline
Close and be equipped with reinforcement on hole and steering ball end pin mating holes, described reinforcement extends to the two ends in hole and forms boss.
Further, described first connecting portion and second connecting portion be arranged in parallel, and described pars intermedia is inclined at described
Between first connecting portion and second connecting portion, and the angle of described first connecting portion and pars intermedia and second connecting portion and centre
The angle in portion is obtuse angle.
Further, the junction of the junction of described first connecting portion and pars intermedia and pars intermedia and second connecting portion
All processed using rounding, so that connecting portion is more smooth, using effect more preferably, and contributes to eliminating stress concentration
Phenomenon.
Further, described first connecting portion, pars intermedia, the width of second connecting portion and thickness are continuously reduced successively.
By above-mentioned means, in the case of ensureing enough structural strengths, it is effectively reduced and uses material, thus reducing
Production cost.
Further, the surface of described first connecting portion, second connecting portion and pars intermedia adopts bead, ball diameter
For 0.55～0.6mm.
Remarkable result of the present utility model is：Structure is simple, in steering gear spline fitted hole and steering ball end pin mating holes
Be provided with reinforcement so that the junction on pitman arm more has mechanical strength, strengthen propons pitman arm intensity and
Performance；Achieve in steering being reliably connected of pin or axle, eliminate stress concentration phenomenon, improve the anti-tired of pitman arm
Labor ability, effectively prevent the fracture of rocking arm.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the left view of Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model and operation principle are described in further detail.
As shown in Figures 1 and 2, a kind of automobile front axle pitman arm, including first connecting portion 1 and second connecting portion 2, described
Be connected by pars intermedia 3 between first connecting portion 1 and second connecting portion 2, the height of described first connecting portion 1 and pars intermedia 3 with
The height sum of second connecting portion 2 is equal, is provided with steering gear spline fitted hole 4 in described first connecting portion 1, described
It is additionally provided with two connecting portions 2 as steering ball end pin mating holes 5, this steering ball end pin mating holes 5 and described steering gear spline fitted
Hole 4 is conical bore, and the centrage in described steering gear spline fitted hole 4 is mutually flat with the centrage of steering ball end pin mating holes 5
OK, described steering gear spline fitted hole 4 with steering ball end pin mating holes 5 are equipped with reinforcement 6, described reinforcement 6 also to
The two ends in hole extend and form boss.
Referring to accompanying drawing 2, described first connecting portion 1 and second connecting portion 2 be arranged in parallel, and described pars intermedia 3 is inclined at
Between described first connecting portion 1 and second connecting portion 2, and described first connecting portion 1 is connected with the angle of pars intermedia 3 and second
Portion 2 is obtuse angle with the angle of pars intermedia 3.
From figure 2 it can be seen that described first connecting portion 1 is connected with second with the junction of pars intermedia 3 and pars intermedia 3
