Abstract
The utility model relates to an independent front suspension for a four-wheel vehicle, and belongs to the transportation vehicle technology field. In order to make the vehicle run steadily and the service life of the machine part prolong, the utility model designs the independent front suspension. The utility model is a bilateral symmetrical structure; a left side structure comprises a steering bracket 3, an oscillating arm 5, and a damping spring 11, wherein the upper end of the oscillating arm 5 is hinged with a vehicle frame 90 and the lower end thereof is hinged with a hang ear 4 suited outside the steering bracket; the both ends of the damping spring 11 are respectively hinged with the oscillating arm 5 and the vehicle frame 90, the hinged point of the damping spring 11 and the vehicle frame is positioned above the hinged point of the oscillating arm 5 and the vehicle frame. The utility model is characterized in that the upper end of the other oscillating arm 1 is hinged with the vehicle frame 90, and the other end thereof is hinged with a hang ear 2 suited outside the steering bracket; two oscillating arms are arranged up and down and in parallel mutually, and formed a parallelogrammic connecting rod structure with the steering bracket 3 and the vehicle frame 90.
Description
Technical field
The utility model belongs to technical field of transportation means, relates in particular to the independent forward mounting of four-wheeled.
Background technology
As application number is 200620081894.2 Chinese patent independent forward mounting that introduce and existing other four-wheeled, all has only a rocking arm to connect vehicle frame and its turning rack for each front-wheel.Such structure cans be compared to holds a stock with one hand, is difficult to guarantee the steady of this turning rack, is difficult to consequently guarantee that vehicle front-wheel stands on ground, not steady under steam, the service life of also having reduced parts.
Summary of the invention
The purpose of this utility model provides a kind of independent forward mounting of four-wheeled, and it can guarantee that vehicle front-wheel stands on ground.
The technical solution of the utility model is: add a rocking arm on the existing structure basis, two rocking arms of arranging up and down are parallel to each other, with the bar linkage structure of turning rack and vehicle frame formation parallelogram.That is:
A kind of independent forward mounting of four-wheeled is the left-right symmetric structure; Its left side structure comprises a turning rack, a swing arm is arranged, its upper end is hinged in vehicle frame and its lower end is hinged in that hangs that is sleeved on outside the turning rack, have its two ends of damping spring to be hinged with swing arm and vehicle frame respectively, the hinge point of damping spring and vehicle frame is positioned at the top of the hinge point of swing arm and vehicle frame; It is characterized in that: another swing arm is arranged, and its upper end is hinged in vehicle frame and its lower end is hinged in that hangs that is sleeved on outside the turning rack; Two swing arms are arranged up and down and are parallel to each other, with the bar linkage structure of turning rack and vehicle frame formation parallelogram.
The beneficial effects of the utility model: as can be known by the characteristics of said structure and parallel four-bar linkage structure, on the turning rack of the present utility model two hang you line and vehicle frame on the line keeping parallelism of hinge point of two swing arms, so promptly can guarantee vehicle upright in ground, thereby reach goal of the invention.
Description of drawings
Below in conjunction with embodiment the utility model is illustrated:
Fig. 1 is (main looking) of the present utility model scheme drawing.
The specific embodiment
As shown in the figure, a kind of independent forward mounting of four-wheeled is the left-right symmetric structure; Its left side structure comprises a turning rack 3, a swing arm 5 is arranged, its upper end be hinged in vehicle frame 90 and its lower end be hinged in be sleeved on turning rack outer hang you 4, have a damping spring 11 its two ends to be hinged with swing arm 5 and vehicle frame 90 respectively, the hinge point of damping spring 11 and vehicle frame is positioned at the top of the hinge point of swing arm 5 and vehicle frame; It is characterized in that: another swing arm 1 is arranged, its upper end be hinged in vehicle frame 90 and its lower end be hinged in be sleeved on turning rack outer hang you 2; Two swing arms (1 and 5) are arranged up and down and are parallel to each other, with the bar linkage structure of turning rack 3 and vehicle frame 90 formation parallelogram.As shown in the figure, the utility model all hangs you and all is connected to vehicle frame by swing arm at the two ends up and down of turning rack 3, cans be compared to the two ends that both hands hold on stock, so turning rack 3 has advantages of higher stability.
