The knuckle arm can be installed in a narrow installation environment without interference, and stress concentration is avoided.
Description
Technical Field
The utility model relates to a vehicle front axle steering system, in particular to a vehicle steering knuckle arm.
Background
In the prior art, a steering transmission mechanism of a front axle of a vehicle includes a knuckle, a knuckle arm, and a trapezoidal arm. Wherein, knuckle arm and trapezoidal arm are connected on the knuckle, and the tie rod is connected with trapezoidal arm, and turns to the tie rod and be connected with the knuckle arm, through turning to the tie rod with the power of vehicle steering gear output on the knuckle arm conveying to the knuckle, the knuckle rethread trapezoidal arm with power transmission to the tie rod to realize turning to of wheel.
When an existing knuckle arm is installed, the existing knuckle arm is easily interfered by other parts, and due to the fact that the installation environment is narrow, the installation and fixation of a tie rod can be affected by the other parts, and meanwhile stress concentration can occur to cause damage to the tie rod.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems in the prior art and provides a vehicle steering knuckle arm.
In order to achieve the purpose, the utility model adopts the following technical scheme: the utility model provides an automobile-used knuckle arm, includes the knuckle arm body, sets firmly first connecting seat and the second connecting seat at knuckle arm body both ends, the knuckle arm body is for certainly first connecting seat to the crooked platykurtic structure that the second connecting seat is buckled and is extended and form, the knuckle arm body certainly its focus is to one side skew when first connecting seat is outwards buckled, so that first connecting seat with the axial lead of second connecting seat is not on same straight line, the width of knuckle arm body certainly first connecting seat to the second connecting seat reduces gradually.
The knuckle arm body includes a first side surface and a second side surface, and an area of the first side surface is larger than an area of the second side surface.
The maximum width of the knuckle arm body is smaller than the width of the first connecting seat, and the width of the first connecting seat is larger than the width of the second connecting seat.
The width of the first connecting seat is a, the distance between the center lines of the first connecting seat and the second connecting seat is b, and a is more than 2b and less than 2.5 b.
The first connecting seat is provided with a first through hole penetrating through the front surface and the rear surface of the first connecting seat, the second connecting seat is provided with a second through hole penetrating through the upper surface and the lower surface of the second connecting seat, and the axis of the first through hole is vertical to the axis of the second through hole.
The second connecting seat is of a cylindrical structure, and the minimum width of the steering knuckle arm body is smaller than the diameter of the second connecting seat.
In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that: can have no interference installation in narrow and small installation environment, avoid stress concentration.

FIG. 1 is a schematic structural view of a knuckle arm for a vehicle according to the present invention;
FIG. 2 is a left side view of FIG. 1;
fig. 3 is a top view of fig. 1.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 3, the present invention is a knuckle arm for a vehicle, including a knuckle arm body 1, and a first connecting seat 2 and a second connecting seat 3 fixedly disposed at two ends of the knuckle arm body 1, wherein the first connecting seat 2 is used for being connected and fixed with a steering rod, and the second connecting seat 3 is used for being connected and fixed with a wheel-side knuckle.
Under this embodiment, knuckle arm body 1 is the crooked platykurtic structure that extends to form from first connecting seat 2 to second connecting seat 3 is buckled, and its focus is to one side skew when knuckle arm body 1 outwards buckles from first connecting seat 2 to make the axial lead of first connecting seat 2 and second connecting seat 3 not on same straight line, so set up, the transmission function of automobile-used knuckle arm has been increased, in addition, the width of knuckle arm body 1 reduces from first connecting seat 2 to second connecting seat 3 gradually.
Specifically, the knuckle arm body 1 includes a first side surface 11 and a second side surface 12, and the area of the first side surface 11 is larger than that of the second side surface 12. The maximum width of the knuckle arm body 1 is smaller than the width of the first connecting seat 2, and the width of the first connecting seat 2 is larger than the width of the second connecting seat 3.
Referring to fig. 1, the width of the first connecting seat 2 is a, the distance between the center lines of the first connecting seat 2 and the second connecting seat 3 is b, and 2b < a < 2.5 b.
The first connecting seat 2 is provided with a first through hole 21 penetrating through the front and rear surfaces thereof, the second connecting seat 3 is provided with a second through hole 31 penetrating through the upper and lower surfaces thereof, and the axis of the first through hole 21 is perpendicular to the axis of the second through hole 31. Specifically, two first through holes 21 are spaced on the first connecting seat 2, and the centers of the two first through holes 21 are on the same horizontal line. The first connecting seat 2 is fixedly connected with the steering pull rod through the first through hole 21, and the second through hole 31 of the second connecting seat 3 is fixedly connected with the wheel-side steering knuckle.
In addition, the second connecting seat 3 is a cylindrical structure, and the minimum width of the knuckle arm body 1 is smaller than the diameter of the second connecting seat 3.
The vehicle steering knuckle arm provided by the utility model avoids interference of other parts, is convenient to mount and avoids the problem of stress concentration.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
