Abstract
The hoisting and servo steering air suspension axle consists of one front axle and one fixed longitudinal beam, and features two bearing air bags set on two hoisting arm brackets and below the fixed longitudinal beam, the hoisting arm with one end connected to hoisting air bag and the other end connected to the elevating bracket, the front axle with steering air bag with one end connected to the steering lever assembly, and steering knuckle arms set on two ends of the steering lever assembly. By means of the said configuration, the present invention can realize the servo steering during bearing by means of the controllable pressure of the steering air bag. The said technology utilizes air bag to drive the steering lever for servo steering, and has excellent steerability, dynamic property and fuel oil efficiency.
Description
Technical field
The present invention relates to a kind of auto parts and components, definite a kind of follow-up steering Pneumatic Suspension bridge that promotes of saying so.
Background technology
At present, the behavior of transfiniting of country promulgation " about carry out the transfinite embodiment of improvement work of overload of vehicle in the whole nation " keypoint treatment overload of vehicle, issued GB GB1589 strict regulations simultaneously vehicle dimension and mass parameter, heavy truck is to the multiaxis development in the encouragement, and it is in line with international standards to promote in the China, heavily to block market.The promoted diverted air of domestic production at present hangs bridge can realize follow-up steering when advancing carrying, but can not when reversing, this is because the kingpin caster angle of wheel can not make the wheel self-aligning when reversing, so in reversing to the side limit of turning, and then when opposite side was turned, the lift bridge wheel can not follow-up steering and is taken place stuck.
Summary of the invention
The objective of the invention is floating axle is raised up, stuck phenomenon takes place to avoid the lift bridge wheel in turning to when not participating in moveing backward.
For reaching above purpose, can promote follow-up steering Pneumatic Suspension bridge, mainly by front axle 15, fixedly longeron 4 is formed, and it is characterized in that, is provided with two lift arm carriages 7 on front axle 15, on two lift arm carriages 7, fixedly the lower end of longeron 4 be provided with two the carrying air bags 5; One end of lift arm 9 is connected with lifting air bag 3, and the other end is connected with shears 8; Be provided with on front axle 15 and turn to air bag 10, turn to an end of air bag 10 to be connected with tierod assembly 11, the two ends of tierod assembly 11 are respectively equipped with track arm 12; Stabilizer rod 13 by hinge with front axle 15 and fixedly longeron 4 link together.
The present invention on basis to the research of domestic following steering axle, the follow-up steering when designing controllable pressure that a kind of utilization turns to air bag and realizing carrying, the core of this technology is to utilize air bag to promote tierod and realize follow-up steering.Because follow-up steering when having realized reversing, the then top drawback of being mentioned all can be avoided, and can obtain better road-holding property, dynamic property and fuel economy.
Description of drawings
Now the present invention is further illustrated in conjunction with the accompanying drawings
Fig. 1 is a front view of the present invention
Fig. 2 is a birds-eye view of the present invention
Fig. 3 is a left view of the present invention
Among the figure 1, wheel hub combination 2, brake band air chamber assembly 3, promote air bag 4, fixedly longeron 5, carrying air bag 6, air bag carriage 7, lift arm carriage 8, shears 9, lift arm 10, turn to air bag 11, tierod assembly 12, track arm 13, stabilizer rod 14, bumper 15, front axle 16, a left side/right steering joint belt material to overlap assembly
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, fixedly longeron 4 links to each other with vehicle frame, finish whole being connected of follow-up steering Pneumatic Suspension bridge and car load support that promote, fixedly longeron and carrying air bag 5, by air bag carriage 6 with turn to front axle 15 to link together, play a supportive role and cushioning effect.The carrying air bag is adjusted air pressure according to the variation of condition of road surface and bearing load, can improve the traveling comfort taken and the impact failure of road pavement greatly.About each 1 stabilizer rod 13 with front axle 15 and fixedly longeron 4 link together by hinging manner, suspension and axletree are formed an integral body, bear that vehicle is exercised, the side force when turning.
When vehicle zero load or load were little, chaufeur put on the air to promoting air bag 3 by the direction switch of director plate, carry air bag 5 venting simultaneously, lift arm 9 promotes vehicle bridge by the diagram left-hand revolution, the wheel built on stilts reduces Tyte Wear and oil consumption.
Work as Ackermann steer angle, turn to air bag 10 effect tierod assemblies 11, tie rod assembly forces on a left side/right steering joint arm 12, and a left side/right steering joint arm imposes steering torque for a left side/right steering joint belt material cover assembly 16, finish the follow-up steering of wheel, 27 ° of the steering locking angles of this product design.
By left and right sides steering swivel belt material cover assembly 16, brake assembly 2 and wheel hub combination 1 are linked together the wheel braking when finishing the vehicle enforcement.
