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 leading arm assembly.
Background technology
Suspension is the general name of attachment means between the vehicle frame of automobile and vehicle bridge or wheel for power transmission, its effect is the power between transmission wheel and vehicle frame and power torsion, and buffering the impulsive force being passed to vehicle frame or vehicle body by uneven road surface, the vibrations that decay thus causes, to ensure that automobile can smoothly travel.Modern vehicle is applied to the air suspension in suspension more and more, diversified change is there is also with constantly developing of technology as one of the most important ingredient of air suspension leading arm, now with the raising of the comfortableness of oversize vehicle, leading arm needs corresponding change the most therewith.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of elasticity of plate spring utilization rate maximized leading arm assembly.
In order to solve above-mentioned technical problem, the present invention provides following technical scheme: leading arm assembly, including leaf spring, leaf spring includes the first leaf spring being connected with lining and the second leaf spring being connected with air spring, is additionally provided with intermediate plate spring between two leaf springs；One end of first leaf spring is provided with grasswort, and grasswort matches with the lining on vehicle frame, and the other end is provided with the connecting platform connecting air spring；First leaf spring, the second leaf spring and intermediate plate spring are equipped with the canned paragraph of one section of level, and the canned paragraph of the first leaf spring is centrally located, and the canned paragraph of three leaf springs connects fixing by pin；Cylinder center's line of grasswort and the canned paragraph neutral line of the first leaf spring flush；Second leaf spring is provided with bag ear near one end of grasswort, and bag ear is to be rotated down end from the top of grasswort around grasswort to flush with the minimum point of grasswort；Grasswort and bag ear are provided with gap in the horizontal direction；Between pin and grasswort, space mutually it is provided with between three leaf springs.
Technique scheme is directed to the composition of arm and is transformed to three leaf springs and is used in conjunction with each other; the grasswort of the first leaf spring is directly connected with lining; connecting platform connects air spring; second leaf spring provides enough protection as the spring of auxiliary for the first leaf spring; the when of work, the pressure suffered by the first leaf spring makes the first leaf spring deform upon; and interact pressure transmission to the second leaf spring, the second leaf spring and the first leaf spring so that the elastic force utilization rate of two leaf springs reaches to maximize；Operationally can produce upper and lower vibration due to leaf spring, so that the horizontal length that leaf spring is in overall structure can occur trickle change, therefore the gap between grasswort and bag ear is contemplated to the first leaf spring and improves the standard the space of length change；Space between three leaf springs is in order to after allowing the elastic force utilization rate of the first leaf spring reach maximum, the second leaf spring carries out operation again.
Further restriction as technique scheme, in order to prevent jumping between the second leaf spring and intermediate plate spring, being provided with the groove being mutually matched and fin between the second leaf spring and intermediate plate spring, simultaneously in order to reduce the friction between canned paragraph leaf spring, the canned paragraph of adjacent leaf spring is provided with pad.
Accompanying drawing explanation
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings:
Fig. 1 is the structure diagram of leading arm assembly embodiment of the present invention.
Detailed description of the invention
As it is shown in figure 1, the leading arm assembly that the present invention provides, including leaf spring, leaf spring includes the first leaf spring 8 being connected with lining 2 and the second leaf spring 4 being connected with air spring, is additionally provided with intermediate plate spring 7 between two leaf springs；One end of first leaf spring 8 is provided with grasswort, and grasswort matches with the lining 2 on vehicle frame, and the other end is provided with the connecting platform connecting air spring；First leaf spring the 8, second leaf spring 4 and intermediate plate spring 7 are equipped with the canned paragraph of one section of level, and the canned paragraph of the first leaf spring 8 is centrally located, and the canned paragraph of three leaf springs connects fixing by pin 6；Cylinder center's line of grasswort and the canned paragraph neutral line of the first leaf spring 8 flush；Second leaf spring 4 is provided with bag ear 1 near one end of grasswort, and bag ear 1 is to be rotated down end from the top of grasswort around grasswort to flush with the minimum point of grasswort；Grasswort and bag ear 1 are provided with gap in the horizontal direction；Mutually being provided with space between three leaf springs between pin 6 and grasswort, be provided with the groove 3 being mutually matched and fin between the second leaf spring 4 and intermediate plate spring 7, the canned paragraph of adjacent leaf 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, on the premise of without departing from present configuration, it is also possible to make some deformation and improvement, these are all without affecting effect and the practical applicability that the present invention implements.
Claims (2)
