Description
Technical field
The utility model belongs to the airsuspension system field of automobile, is specifically related to the guide arm in a kind of vehicle air suspension system.
Background technology
In existing airsuspension system, the air bellow of air suspension of automobile in use only bears vertical load, therefore in air suspension, must transmit longitudinal force and side force with guiding mechanism, air spring guiding arm is exactly a kind of guiding mechanism in vehicle air suspension system, it plays a part connection between wheel and vehicle frame, except bearing the weight of self compartment in a small amount and load, also to bear because the caused impact load of Uneven road and torque load.
Existing guide arm body and platform are connected in same level often, in vehicle air suspension system, people contact with tire for fear of air bellow, take eccentric manner to connect air bellow and guide arm, bear because of the caused impact load of Uneven road and torque load once air bellow, easily cause air bellow because of discontinuity run-off the straight, air bellow is reduced service life, even lost efficacy or damaged; Meanwhile, guide arm body shape entirety is in the past notch cuttype conventionally, makes bulk strength and the less stable of guide arm.
Utility model content
The purpose of this utility model is to provide the guide arm in a kind of vehicle air suspension system, and this guide arm bulk strength is high, good stability, the life-span that can improve air bellow.
To achieve these goals, the utility model provides following technical scheme: the guide arm in vehicle air suspension system, comprise guide arm body, one end of this guide arm body is provided with grasswort, the other end is connected with the platform of support air bellow, platform is provided with the screw for air bellow is installed, one side of described its connecting platform of guide arm body is shaped as inverted trapezoidal, between guide arm body and platform, there is the angle of 165 degree～175 degree, on the guide arm body being connected with platform, be also provided with mounting hole, between the screw on described mounting hole and platform, form leg-of-mutton position relationship.
The utility model has the advantage of: on guide arm body, adopt inverted trapezoidal structure, in the time that air bellow bears vertical load, can effectively reduce the stress of guide arm body and platform junction, improve the bulk strength of guide arm, in the time that air bellow bears because of the caused impact load of Uneven road and torque load, owing to thering is the angle of 165 degree～175 degree between guide arm body and platform, air bellow can be distributed to two different planes by impact load and torque load, with respect to the air bellow in a plane on stepped appearance, be difficult for causing that air bellow is because of discontinuity run-off the straight, thereby improve the service life of air bellow, between the screw on mounting hole and platform, form leg-of-mutton position relationship, air bellow coordinates with screw by mounting hole to install to be fixed, and can play firm effect.
As preferred version, need limit the angle between guide arm body and platform, the angle between guide arm body and platform is made as 170 degree.
As preferred version, the inverted trapezoidal structure on guide arm body, its thickness is identical, makes guide arm entirety stressed evenly, good stability.
As preferred version, to draw close to the contact position of guide arm and air bellow bottom for the center of gravity that makes guide arm body, the thickness of guide arm body is from grasswort to inverted trapezoidal structure, and its thickness increases to the thickness of inverted trapezoidal structure gradually.
As preferred version, mounting hole is identical with the diameter of screw.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the guide arm embodiment in the utility model vehicle air suspension system;
Fig. 2 is the birds-eye view of the guide arm embodiment in the utility model vehicle air suspension system.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, guide arm in vehicle air suspension system, comprise guide arm body 1, one end of this guide arm body 1 is provided with grasswort 2, the other end is connected with the platform 3 of support air bellow, platform 3 is provided with the screw 4 for air bellow is installed, one side of guide arm body 1 its connecting platform is shaped as inverted trapezoidal, between guide arm body 1 and platform 3, there is the angle of 170 degree, inverted trapezoidal structure 6 on guide arm body 1, its thickness is identical, the thickness of guide arm body 1 is from grasswort 2 to inverted trapezoidal structure 6, its thickness increases to the thickness of inverted trapezoidal structure 6 gradually.
As shown in Figure 2, on the guide arm body 1 being connected, be also provided with mounting hole 5 with platform 3, form leg-of-mutton position relationship between the screw 4 on mounting hole 5 and platform 3, mounting hole 5 is identical with the diameter of screw 4.
When work, on guide arm body 1, adopt inverted trapezoidal structure 6, in the time that air bellow bears vertical load, can effectively reduce the stress of guide arm body 1 and platform 3 junctions, improve the bulk strength of guide arm, in the time that air bellow bears because of the caused impact load of Uneven road and torque load, owing to thering is the angle of 170 degree between guide arm body 1 and platform 3, air bellow can be distributed to two different planes by impact load and torque load, with respect to the air bellow in a plane on stepped appearance, be difficult for causing that air bellow is because of discontinuity run-off the straight, thereby improve the service life of air bellow, between the screw 4 on mounting hole 5 and platform 3, form leg-of-mutton position relationship, air bellow coordinates with screw 4 to install by mounting hole 5 to be fixed, and can play firm effect, in addition, need limit the angle between guide arm body 1 and platform 3, the angle between guide arm body 1 and platform 3 is made as 170 degree, inverted trapezoidal structure 6 on guide arm body 1, its thickness is identical, makes guide arm entirety stressed evenly, good stability, draw close to the contact position of guide arm and air bellow bottom for the center of gravity that makes guide arm body 1, the thickness of guide arm body 1 is from grasswort 2 to inverted trapezoidal structure 6, and its thickness increases to the thickness of inverted trapezoidal structure 6 gradually.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
