Abstract
The utility model relates to a front axle steering knuckle arm. The front axle steering knuckle arm comprises a steering knuckle arm body, wherein the steering knuckle arm body is formed by a front arm body and a rear arm body, shaft axes of the front arm body and the rear arm body are not located on the same straight line, and an included angle theta of the shaft axes of the front arm body and the rear arm body is 12-15 degrees. The front axle steering knuckle arm disclosed by the utility model has the beneficial effects that steering can be easier due to the arrangement of the included angle of the front arm body and the rear arm body, meanwhile, sideslip of a tire is avoided or reduced, thus the service life of the tire is prolonged, and the stability when a vehicle turns is increased; the front arm body and the rear arm body are connected through a conical shaft, the integral firmness is increased, meanwhile, the stability of the stepped shaft-shaped rear arm body is better, and the strength is higher.
Description
Technical field
The utility model relates to Automotive Steering Technology field, especially relates to a kind of front axle track arm.
Background technology
Front axle is one of vitals of car chassis, and front axle is connected with vehicle frame or vehicle body by suspension system, two ends installing wheel, the application force of all directions between transmission vehicle frame or vehicle body and wheel; Under normal circumstances, front axle has not only born the vertical load from frame or vehicle body, and in vehicle traveling process, also bears landing ground and transmit the impact load of coming by wheel, and the quality of front axle performance directly has influence on the safety performance of car load.
General, steeraxle comprises front-axle beam steering swivel, track arm and wheel hub etc., steeraxle is to utilize steering swivel to make wheel deflection certain angle, to reach the object of automobile turning, steeraxle is except bearing vertical load, also bear automobile brake and acceleration etc. are former thereby produce longitudinal force and the side force that causes of automobile turning, and the effect of the moment that causes of these power, stressed complexity; Whole bar of current existing track arm be all with the assembled portion with tapering on same axis, this makes in the time that intermediate rod is contained in the front of propons intermediate rod, track arm and front axle to form and turns to ladder type, makes tire easily occur premature wear.
Therefore, a kind of reasonable in design, can effectively prevent that the appearance of front axle track arm of wear on tyres is necessary.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, and a kind of reasonable in design is provided, and whole bar of track arm and the assembled portion of this bar band tapering be not in same axis front axle track arm.
The technical matters that the utility model solves realizes by the following technical solutions:
Front axle track arm, comprise track arm body, described track arm body is made up of forearm body and postbrachium body, and the axial line of described forearm body and postbrachium body is on same straight line, and the angle theta of the axial line of described forearm body and postbrachium body is 12 °～15 °.
As preferred technical scheme, the angle theta of the axial line of described forearm body and postbrachium body is 15 °.
As preferred technical scheme, between described forearm body and postbrachium body, be also provided with taper shaft, further, the tapering of described taper shaft is 18 °.
As preferred technical scheme, described postbrachium body is stepped shaft shape.
The beneficial effect the utlity model has is: the angle setting of (1) forearm body and postbrachium body, and be more prone to transition, avoid simultaneously or reduce tire and break away, thus the service life of prolongation tire, the stability of raising Ackermann steer angle;
(2) forearm body is connected by taper shaft with postbrachium body, has improved overall steadiness, and the stability of the postbrachium body of stepped shaft shape is better simultaneously, and intensity is larger.
Brief description of the drawings
In order to be illustrated more clearly in embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model: a kind of structural representation of front axle track arm.
Detailed description of the invention
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Fig. 1, front axle track arm, comprise track arm body 1, track arm body 1 is made up of forearm body 11 and postbrachium body 12, and the axial line of forearm body 11 and postbrachium body 12 is not on same straight line, the angle theta of the axial line of forearm body 11 and postbrachium body 12 is 12 °～15 °, and the angle theta of the forearm body 11 in the present embodiment and the axial line of postbrachium body 12 is 15 °.
In order to ensure the stable connection of forearm body 11 and postbrachium body 12, between forearm body 11 and postbrachium body 12, be also provided with taper shaft 13, the tapering of taper shaft 13 is 18 °, postbrachium body 12 is stepped shaft shape.
The utility model, by the angle setting of forearm body 11 and postbrachium body 12, is more prone to transition, and avoid simultaneously or reduce tire and break away, thus the service life of prolongation tire, the stability of raising Ackermann steer angle; Forearm body 11 is connected by taper shaft 13 with postbrachium body 12, has improved overall steadiness, and the stability of the postbrachium body 12 of stepped shaft shape is better simultaneously, and intensity is larger.
More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
