Abstract
The utility model discloses a composite pneumatic suspension of a semitrailer. The composite pneumatic suspension comprises an axle support, a composite connecting rod, a lock catch ring, a composite spring plate, an air damper, an axle and axle clips, and is characterized in that the axle is arranged on the lower side in the middle of the composite spring plate, the axle clips are arranged on the upper side and the lower side of the axle, the axle and the composite spring plate are connected together by the axle clips through the lock catch ring, the axle support is arranged on one end of the composite spring plate, the air damper is arranged on the other end of the composite spring plate, and the composite connecting rod is arranged between the axle and the axle support. The composite pneumatic suspension, provided by the utility model, has the advantages of simple structure, convenience for maintenance and low using cost, and capability of improving the stability of a body, and improving the comfortableness of the semitrailer when the semitrailer runs on a low-speed rough road surface for a long time.
Description
Technical field
The utility model belongs to the vehicle technology field, the composite air suspension that a kind of superimposed trailer of saying so more specifically uses.
Background technology
What the superimposed trailer suspension of prior art adopted usually is leaf spring suspension and air suspension; The leaf spring suspension in use, ride comfort is bad, particularly for a long time when the uneven road traveling of low speed; The traveling comfort of leaf spring suspension is very poor; Can not regulate well, change these performances, big, the capable of using space of the transformation difficulty of leaf spring suspension is limited, the change work capacity is big, cost is higher; And the air suspension complex structure of prior art, the working service cost is higher.
Summary of the invention
In order to address the above problem; The utility model provides a kind of superimposed trailer composite air suspension; Composite air suspension principle of work forms pressurized air with air compressor exactly, and pressurized air is delivered in the energy chamber of spring and air suspension bumper, changes the height of vehicle with this.Utilize the output signal of height sensor, declare the variation of bodywork height, control compressor and blow off valve again, make length of spring compressed or elongation, thereby play the effect of vibration damping.
Described superimposed trailer composite air suspension is made up of axle stand, composite rod, snap close ring, complex spring plate, air bumper, axletree, axle card; The middle part downside that it is characterized in that the complex spring plate is provided with axletree; The both sides up and down of axletree are provided with the axle card, and the axle cartoon is crossed the snap close ring axletree and complex spring plate even are bound up, and an end of complex spring plate is provided with axle stand; The other end of complex spring plate is provided with air bumper, between axletree and the axle stand composite rod is set.
The beneficial effect of the utility model is that superimposed trailer composite air suspension frame structure is simple, easy to maintenance, and use cost is low, and the composite air suspension has improved the stability of vehicle body, and the semitrailer length time is improved the traveling comfort of car when the road traveling of low speed injustice.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model; In the accompanying drawing:
1. axle stand, 2. composite rod, 3. snap close ring, 4. complex spring plate, 5. air bumper, 6. axletree, 7. a card.
The specific embodiment
In conjunction with accompanying drawing the utility model is described in further detail; So that the public grasps the implementation method of the utility model better; The concrete embodiment of the utility model is: described superimposed trailer composite air suspension is made up of axle stand 1, composite rod 2, snap close ring 3, complex spring plate 4, air bumper 5, axletree 6, axle card 7; The middle part downside that it is characterized in that complex spring plate 4 is provided with axletree 6; The both sides up and down of axletree 6 are provided with a card 7, and axle card 7 even is bound up axletree 6 and complex spring plate 4 through snap close ring 3, and an end of complex spring plate 4 is provided with axle stand 1; The other end of complex spring plate 4 is provided with air bumper 5, between axletree 6 and the axle stand 1 composite rod 2 is set.
The beneficial effect of the utility model is that superimposed trailer composite air suspension frame structure is simple, easy to maintenance, and use cost is low, and the composite air suspension has improved the stability of vehicle body, and the semitrailer length time is improved the traveling comfort of car when the road traveling of low speed injustice.
