Abstract
The invention discloses a heavy car air suspension, and relates to the technical field of car manufacturing. The heavy car air suspension comprises a car frame, guide arms connected with axles through U-shaped bolts are arranged on the lower portions of longitudinal beams on the two sides of the car frame respectively, one ends of the guide arms on the two sides are in lap joint through a transverse joist, and air springs connected with the longitudinal beams on the two sides of the car frame respectively are arranged on the joist. The other end of each guide arm is connected with the corresponding longitudinal beam of the car frame through a guide arm support, limiting blocks are arranged at the positions, above the axles, of the car frame, and dampers connected with the axles and the car frame are arranged between the guide arms and the car frame. Compared with the prior art, the problems that the self weight of a plate spring suspension adopted in an existing heavy car is high, and running smoothness is poor can be solved.
Description
Technical field
The present invention relates to field of automobile, especially a kind of air suspension for heavy motor vehicle.
Background technology
Along with the raising that increase and the people of highway transportation volume require towing vehicle travelling comfort, road-holding property, ride comfort, the draft hitch of practitioner to tractor truck in the urgent need to auto manufacturing improves; Existing HD truck, especially the suspension of HD truck adopts plate spring suspension brackets mostly, but in use there are the following problems for plate spring suspension brackets: 1, non-adjustable from rigidity that is heavy, steel spring, unit mass energy storage capacity is low, noise is high, not only make heavy motor vehicle ride comfort under steam and traveling comfort poor, but also affect the economy of heavy motor vehicle.
Summary of the invention
Problem solved by the invention is to provide a kind of heavy motor vehicle air suspension, with solve existing heavy motor vehicle adopt plate spring suspension brackets from heavy and problem that is riding comfort difference.
In order to solve the problem, the technical solution used in the present invention is: this heavy motor vehicle air suspension includes vehicle frame, the guide arm be connected with vehicle bridge by U-bolt is respectively equipped with in the below of described vehicle frame two side girder, one end of the described guide arm of both sides is overlapped by the joist of a transverse direction, and described joist is respectively equipped with the air bellow be connected with the longeron of described vehicle frame both sides; The other end of each described guide arm is all connected by the longeron of guide arm bearing with described vehicle frame; Described vehicle frame is equipped with limiting stopper above described vehicle bridge, is provided with the bumper being connected described vehicle bridge and described vehicle frame between described guide arm with described vehicle frame.
In above-mentioned heavy motor vehicle air suspension technical scheme, technical scheme can also be more specifically: the top of described vehicle bridge is equipped with the lateral rod that one end is connected with described vehicle bridge by support, and the other end of the described lateral rod above adjacent described vehicle bridge is separately fixed at the inner side of described vehicle frame two side girder.
Further: described air spring height valve is connected with air receiver with guiding valve.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: 1, this air suspension structure falls heavy 260 kilograms relative to biography relative to plate spring suspension brackets; During vehicle operating, air bellow absorbs and stores vehicle vibrational energy, and air suspension rigidity is with load change, and natural frequency is constant, and therefore, heavy motor vehicle riding comfort is good, ride comfort, extends vehicle life span; Noise is low, and safeguard few, use cost is low, and traction is stablized; 2, bumper is connected to vehicle bridge and vehicle frame, plays and slows down ground by the effect of vehicle bridge to the impulsive force of vehicle frame; Lateral rod is connected to vehicle bridge and vehicle frame, plays relative displacement horizontal between restriction vehicle bridge and vehicle frame; Limiting stopper is arranged in directly over vehicle bridge, limits the height that vehicle bridge is jumped, and prevents vehicle bridge and vehicle frame from producing collision damage; 3, air receiver is by levelling valve and guiding valve to air bellow air feed, and levelling valve detects the relative position height of vehicle frame and lower joist, and the inflation/deflation that guiding valve controls to adjust air bellow controls car load height.

Fig. 2 is the K direction view of Fig. 1.
Fig. 3 is the birds-eye view of Fig. 2.
Detailed description of the invention
Below in conjunction with attached Example, the invention will be further described:
Heavy motor vehicle air suspension as shown in Figure 1, Figure 2 and Figure 3 includes vehicle frame 12, be respectively equipped with the guide arm 3 be connected with vehicle bridge (not shown) by U-bolt 4 in the below of vehicle frame 12 liang of side girders, the vehicle frame 12 of the present embodiment is provided with two respectively side by side to the corresponding guide arm 3 be connected with vehicle bridge by U-bolt 4 in the below of two longerons; One end of two guide arms 3 of both sides is overlapped by the joist 5 of a transverse direction, and joist 5 is equipped with two air bellows 6 be connected with the longeron of vehicle frame 12 both sides respectively; Air bellow 6 is connected with air receiver 2 with levelling valve 8 by tracheae, guiding valve 7 successively, and air receiver 2 is contained on vehicle frame 12 by mount pad; The other end of each guide arm 3 is all connected with the longeron of vehicle frame 12 by a guide arm bearing 1; Vehicle frame 12 longeron above vehicle bridge is all equipped with one piece of limiting stopper 11, vehicle frame 12 longeron between guide arm 3 with vehicle frame 12 is all equipped with the bumper 10 be connected with vehicle bridge.The top of described vehicle bridge is equipped with the lateral rod that one end is connected with described vehicle bridge by support, and the other end of the described lateral rod above adjacent described vehicle bridge is separately fixed at the inner side of vehicle frame 12 liang of side girders.The lateral rod that one end is connected with vehicle bridge by support is all equipped with in the top of each vehicle bridge, and the other end of the lateral rod above adjacent vehicle bridge is separately fixed at the inner side of vehicle frame 12 liang of side girders; The present embodiment is equipped with two vehicle bridge at vehicle frame 12, the top of two vehicle bridge is equipped with front lateral rod 13 and rear lateral rod 9 respectively, front lateral rod 13 is connected with vehicle bridge by support respectively with one end of rear lateral rod 9, the other end of front lateral rod 13 is fixed on the inner side of vehicle frame 12 1 side girder by thrust bearing, the other end of rear lateral rod 9 is fixed on the inner side of vehicle frame 12 opposite side longeron by thrust bearing.
During vehicle operating, air bellow absorbs and stores vehicle vibrational energy, and air suspension rigidity is with load change, and natural frequency is constant, and therefore, the ride comfort that heavy motor vehicle travels is good, ride comfort, extends vehicle life span; Noise is low, and safeguard few, use cost is low, and traction is stablized.
