Abstract
The utility model belongs to the field of air suspensions, and discloses a car air suspension guiding arm which comprises a plate spring. The plate spring comprises a first leaf spring connected with a bush and a second leaf spring connected with an air spring, a rolled lug is arranged at one end of the first leaf spring and matched with the bush, the first leaf spring and the second leaf spring are connected through a bolt, the connecting position of the first leaf spring is the end away from the rolled lug, and the connecting position of the second leaf spring is the center in the length direction. A gasket is arranged at the bolt connection position of the two leaf springs, a wrapping lug wrapping the rolled lug is arranged at the hanging end of the second leaf spring, and a platform provided with the air spring is arranged at the other end of the second leaf spring. The guiding arm is composed of the two leaf springs which are used in cooperation, the first leaf spring is directly connected with the bush, the second leaf spring is connected with the air spring, acting forces of the two leaf springs are separated, and elasticity of the leaf springs are utilized to the maximum.
Description
Technical field
The utility model belongs to air suspension field, is specifically related to air suspension of automobile guide arm.
Background technology
Suspension is the general name for the connecting device of power transmission between the vehicle frame of automobile and vehicle bridge or wheel, its effect is that power and the power transmitted between wheel and vehicle frame are turned round, and buffering is passed to the impulsive force of vehicle frame or vehicle body by uneven road surface, the vibrations that decay causes thus, to ensure that automobile can smoothly travel.Modern vehicle is applied to the air suspension in suspension more and more, also there is diversified variation along with the continuous differentiation of technology as one of the most important component part of air suspension guide arm, the raising of the current traveling comfort along with full size vehicle, guide arm also needs to have corresponding variation thereupon.
Utility model content
The technical problems to be solved in the utility model is to provide the maximized air suspension of automobile guide arm of a kind of elasticity of plate spring degree of utilization.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: air suspension of automobile guide arm, comprise steel spring, steel spring has the first spring being connected with lining and second spring being connected with air bellow, one end of first spring is provided with grasswort, and grasswort and lining match; Between first spring and second spring, be bolted, the connection location of first spring is the one end away from grasswort, and the connection location of second spring is the center on its length direction; Between two springs, be provided with pad in bolted place, the suspended end of second spring is provided with the bag ear of coated grasswort, and the other end is provided with the platform that air bellow is installed; The end points up and down of inside face and the end points up and down of grasswort outside face of bag ear contact, in the horizontal direction away from one end grasswort of bolt and wrap between ear and be provided with gap; The lower surface of first spring between bolt and grasswort is dip plane, and the upper surface of dip plane and second spring forms triangle space, the space smoothing transition that grasswort is adjacent with bag ear; The maximum height of triangle space is no more than the thickness of 1/2 first spring.
Technique scheme is transformed to two sheet springs by the composition of guide arm and is used in conjunction with each other, and first spring is directly connected with lining, and second spring is connected with air bellow, and two spring disagglutinating action power make the elastic force of sheet spring obtain maximum utilization; The bag ear of second spring is grasswort and first spring to be protected when the grasswort et out of order in order to prevent; Because sheet spring time can produce upper and lower vibration in work, thereby make the horizontal length of sheet spring on integral structure that trickle variation can occur, therefore grasswort is exactly for the improve the standard space of length variations of first spring with wrapping gap between ear; Triangle space is to carry out operation in order to allow the elastic force degree of utilization of first spring reach maximum rear second spring again, and pad is in order to reduce by two frictions between spring, further the elastic force degree of utilization of sheet spring to be mentioned the highest.
As the further restriction of technique scheme, for fixed air spring better, on the platform of second spring, be provided with screw, screw is arranged in a row on sheet spring length direction, due to 2 definite straight lines, in order to prevent that air bellow from use jumping, the quantity of screw is at least three.
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 structure diagram of the utility model air suspension of automobile guide arm embodiment.
Detailed description of the invention
As shown in Figure 1, the air suspension of automobile guide arm that the utility model provides, comprises steel spring, and steel spring has the first spring 2 being connected with lining 1 and second spring 3 being connected with air bellow, one end of first spring 2 is provided with grasswort, and grasswort and lining 1 match; Between first spring 2 and second spring 3, be connected by bolt 5, the connection location of first spring 2 is the one end away from grasswort, and the connection location of second spring 3 is the center on its length direction; The suspended end that the place connecting at bolt 5 between two springs is provided with 4, the second springs 3 of pad is provided with the bag ear that is coated grasswort, and the other end is provided with the platform that air bellow is installed; The end points up and down of inside face and the end points up and down of grasswort outside face of bag ear contact, in the horizontal direction away from one end grasswort of bolt 5 and wrap between ear and be provided with gap; The lower surface of first spring 2 between bolt 5 and grasswort is dip plane, and the upper surface of dip plane and second spring 3 forms triangle space, the space smoothing transition that grasswort is adjacent with bag ear; The maximum height of triangle space is no more than the thickness of 1/2 first spring 2, on the platform of second spring 3, is provided with screw, and screw is arranged in a row on sheet spring length direction, and the quantity of screw is at least three.
Above-described is only preferred implementation of the present utility model, should be understood that for a person skilled in the art, not departing under the prerequisite of the utility model structure, can also make some distortion and improvement, these can not affect effect and practical applicability that the utility model is implemented.
