Abstract
The invention discloses a guide arm assembly in the field of air suspensions. The guide arm assembly comprises a steel plate spring. The steel plate spring comprises a first leaf spring connected with a bush and a second leaf spring connected with an air spring. A clamping leaf spring is arranged between the two leaf springs. One end of the first leaf spring is provided with a coiled lug. The coiled lug is matched with the bush on a frame and the other end of the first leaf spring is connected with a connection platform connected with the air spring. The end, adjacent to the coiled lug, of the second leaf spring is provided with a covered lug. A gap exists between the coiled lug and the covered lug in the horizontal direction. Gaps are arranged among the three leaf springs between a bolt pin and the coiled lug. According to the guide arm assembly, pressure borne by the first leaf spring enables the first leaf spring to deform and transmit the pressure to the second leaf spring. The first leaf spring and the second leaf spring act on each other, so that the elasticity utilization rate of the two leaf springs is maximized.
Description
Technical field
The invention belongs to air suspension field, be specifically related to guide arm assembly.
Background technology
Suspension is for the general name of 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 guarantee that automobile can smoothly travel.Modern vehicle is applied to the air suspension in suspension more and more, as one of the most important component part of air suspension guide arm, also along with the continuous differentiation of technology, there is diversified variation, the raising of the current traveling comfort along with full size vehicle, guide arm also needs to have corresponding variation thereupon.
Summary of the invention
The technical problem to be solved in the present invention is to provide the maximized guide arm assembly of a kind of elasticity of plate spring degree of utilization.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: guide arm assembly, comprise steel spring, steel spring comprises the first spring being connected with lining and second spring being connected with air bellow, between two springs, is also provided with intermediate plate spring; One end of first spring is provided with grasswort, and the lining on grasswort and vehicle frame matches, and the other end is provided with the connecting platform that connects air bellow; First spring, second spring and intermediate plate spring are equipped with the canned paragraph of one section of level, and the canned paragraph of first spring is positioned at midway location, and the canned paragraph of three springs is connected and fixed by pin; Cylinder center's line of grasswort flushes with the canned paragraph neutral line of first spring; Second spring is provided with bag ear near one end of grasswort, and bag ear is that the top from grasswort is rotated down end around grasswort and flushes with the nadir of grasswort; Grasswort is provided with gap in the horizontal direction with bag ear; Between three springs, between pin and grasswort, be mutually provided with space.
Technique scheme is transformed to three sheet springs by the composition of guide arm and is used in conjunction with each other, the grasswort of first spring is directly connected with lining, connecting platform connects air bellow, second spring provides enough protections as auxiliary spring for first spring, in the time of work, the suffered pressure of first spring makes first spring generation deformation, and pressure is passed to second spring, second spring and first spring interact, and make the elastic force degree of utilization of two springs reach maximization; 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, so the gap between grasswort and bag ear is exactly for the improve the standard space of length variations of first spring; Space between three springs is to carry out operation in order to allow the elastic force degree of utilization of first spring reach maximum rear second spring again.
Further restriction as technique scheme, in order to prevent jumping between second spring and intermediate plate spring, between second spring and intermediate plate spring, be provided with the mutual groove mating and fin, simultaneously in order to reduce the friction between canned paragraph sheet spring, the canned paragraph of adjacent sheet spring is provided with pad.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structure diagram of guide arm assembly embodiment of the present invention.
The specific embodiment
As shown in Figure 1, guide arm assembly provided by the invention, comprises steel spring, steel spring comprise the first spring 8 being connected with lining 2 and 4, two springs of second spring of being connected with air bellow between be also provided with intermediate plate spring 7; One end of first spring 8 is provided with grasswort, and the lining 2 on grasswort and vehicle frame matches, and the other end is provided with the connecting platform that connects air bellow; First spring 8, second spring 4 and intermediate plate spring 7 are equipped with the canned paragraph of one section of level, and the canned paragraph of first spring 8 is positioned at midway location, and the canned paragraph of three springs is connected and fixed by pin 6; Cylinder center's line of grasswort flushes with the canned paragraph neutral line of first spring 8; Second spring 4 is provided with bag ear 1 near one end of grasswort, and bag ear 1 is that the top from grasswort is rotated down end around grasswort and flushes with the nadir of grasswort; Grasswort is provided with gap in the horizontal direction with bag ear 1; Between three springs, between pin 6 and grasswort, be mutually provided with space, between second spring 4 and intermediate plate spring 7, be provided with the mutual groove mating 3 and fin, the canned paragraph of adjacent sheet spring is provided with pad 5.
Above-described is only the preferred embodiment of the present invention, should be understood that for a person skilled in the art, not departing under the prerequisite of structure of the present invention, can also make some distortion and improvement, these can not affect effect of the invention process and practical applicability.
