Description
Technical field
This utility model is related to technical field of automobile parts, is a kind of track rod lever specifically.
Background technology
Drag link and drag link are two major parts of the steering of automobile, and wherein drag link is connection left and right turn
Arm, one can make two wheel synchronizations, and two can align toe-in.Steering linkage end is connected by ball-joint with knuckle, by
In directly exerting oneself, rotation wheel is firmly larger, thus the fluid-link steering that existing major part car is all, mitigate exerting oneself for driver, also make
Turn to more flexible, easy to operate.
However, the work under bad environment of heavy truck and many overload operations, the section of existing front axle tie rod arm is little, intensity
Not enough, often there is propons track rod lever fracture initiation steering failure fault in Jing, so as to cause the accident.
The content of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of track rod lever, the spindle arm
Can adapt to harsh environments, not long service life, easy fracture.
To reach above-mentioned purpose, the technical solution adopted in the utility model is as follows：
A kind of track rod lever, it is critical only that：Including first connecting portion and second connecting portion, the first connecting portion
It is connected by pars intermedia between second connecting portion, the end of the first connecting portion is provided with the first spindle arm bolt and fixes
Hole, is provided with the second spindle arm bolt fixing hole, and first spindle arm between the first connecting portion and pars intermedia
Reinforcement is equipped with bolt fixing hole and the second spindle arm bolt fixing hole, is provided with the end of the second connecting portion and is turned
To ball stud mating holes, in the centrage of the first spindle arm bolt fixing hole and the second spindle arm bolt fixing hole
Heart line is parallel, and with the central axis of the steering ball end pin mating holes.
Further, the first connecting portion is similar to the structure of pars intermedia and equal section is trapezoidal, and described first connects
The longer base of the socket part base longer with pars intermedia is connected.
Further, the first connecting portion is not with the centerline parallel of second connecting portion but conllinear.
Further, the first connecting portion and the junction of pars intermedia and the junction of pars intermedia and second connecting portion
Using rounding process.
Further, the steering ball end pin mating holes is taper hole, the end face of ring set one end that the big end of the taper hole is located
With the distance between axis hole face 2～4mm, the 160～170mm of spacing of a taper hole axis axis hole axis nearest with it.
The distance between end face and axis hole face of the ring set one end at the big end place of taper hole are reduced, stress of cranking arm is eliminated
Concentration phenomenon, improves the anti-fatigue ability of track rod lever.
Further, the surface of the 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：Simple structure, in the first spindle arm bolt fixing hole and the second drag link
Arm bolt fixing hole is provided with reinforcement so that the junction on spindle arm more has mechanical strength, strengthens the horizontal drawing of propons
The intensity and performance of lever arm；The distance between end face and axis hole face of the ring set one end at the big end place of taper hole are reduced simultaneously,
Stress concentration phenomenon of cranking arm is eliminated, the anti-fatigue ability of track rod lever is improve, the fracture cranked arm is effectively prevent.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the left view of Fig. 1.
Specific embodiment
Specific embodiment of the present utility model and operation principle are described in further detail below in conjunction with the accompanying drawings.
As shown in Figures 1 and 2, a kind of track rod lever, including first connecting portion 1 and second connecting portion 2, described first
It is connected by pars intermedia 3 between connecting portion 1 and second connecting portion 2, the end of the first connecting portion 1 is provided with the first spindle arm
Bolt fixing hole 4, is provided with the second spindle arm bolt fixing hole 5 between the first connecting portion 1 and pars intermedia 3, and described
Reinforcement 6 is equipped with first spindle arm bolt fixing hole 4 and the second spindle arm bolt fixing hole 5, is connected described second
The end of socket part 2 is provided with steering ball end pin mating holes 7, the centrage of the first spindle arm bolt fixing hole 4 and second horizontal
The centerline parallel of tie rod arm bolt fixing hole 5, and with the central axis of the steering ball end pin mating holes 7.
Referring to accompanying drawing 1, the first connecting portion 1 is similar to the structure of pars intermedia 3 and equal section is trapezoidal, and described first
The longer base of connecting portion 1 base longer with pars intermedia 3 is connected.
It can further be seen from figure 1 that the first connecting portion 1 is not with the centerline parallel of second connecting portion 2 but conllinear, institute
First connecting portion 1 is stated with the junction of pars intermedia 3 and the junction of pars intermedia 3 and second connecting portion 2 using at rounding
Reason.
It can further be seen from figure 1 that the steering ball end pin mating holes 7 is taper hole, the ring set at the big end place of the taper hole
The distance between the end face of one end and axis hole face 3mm, spacing 170mm of a taper hole axis axis hole axis nearest with it.
In this example, the surface of the first connecting portion 1, second connecting portion 2 and pars intermedia 3 adopts bead, and ball is straight
Footpath is 0.55～0.6mm.
