The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated, should be understood that, the specific embodiment described herein only is used for description and interpretation the present invention, and protection scope of the present invention is not limited to the following specific embodiment.
Fig. 1 shows the schematic diagram of the suspension limiting buffer block arrangement structure of the specific embodiment of the invention.The first limiting buffer block 1 arranges on the damper bracket among the figure, this is the limiting buffer block that existing big-and-middle-sized vehicle generally arranges, the two ends hanger of steel spring 4 is installed on the chassis side rail 5 by the plate spring lifting lug frame, shock absorber 2 be arranged in steel spring 4 near, it mainly plays cushion load with the effect of vibration damping.
Said structure is the conventional arrangement structure on the existing vehicle, under the situation that adopts above-mentioned single limiting buffer block, referring to shown in Figure 2, dotted line represents the variation tendency of vehicle steel spring 4 stressed rear distortion when braking among the figure, as can see from Figure 2, when steel spring 4 deforms being subject to impact load, steel spring 4 should be as fulcrum generation symmetric deformation take axletree under normal circumstances, but owing to be subject to the restriction of the first limiting buffer block 1, so that the distortion of sine wave shape shown in dotted lines in Figure 2 occurs in steel spring 4.In this case, owing to having larger deformation distance between the crest of the steel spring under the normal loaded state and the deformed sine wave shape on Fig. 2 right side, therefore the inconsistent possibility of spring deflection of vehicle both sides increases greatly, for example be subject to greater impact load and impact load that the opposite side steel spring is subject to when little in a side steel spring, be subject to the distortion that the sine wave shape shown in Fig. 2 dotted line occurs the larger steel spring of impact load 4 this moment, and the steel spring 4 of opposite side is because distortion is little, the steel spring 4 of this opposite side can not run into the first limiting buffer block 1 substantially, thereby the distortion of sine wave shape shown in Figure 2 can not occur, and be that normal slight symmetric deformation occurs, this moment, the spring deflection of vehicle both sides was inconsistent, and the running out the way problem very easily occurs.
For this reason, suspension limiting buffer block arrangement structure of the present invention also comprises the second limiting buffer block 3, this second limiting buffer block 3 is arranged between described the first limiting buffer block 1 and the close hinge of leaf spring of this first limiting buffer block 1, preferably, the setting position of this second limiting buffer block 3 is lower than described the first limiting buffer block 1, can more effectively limit like this deformation range of steel spring.
