Abstract
The utility model discloses a trailer air suspension capable of increasing antiroll capability, which is characterized in that the two sides of a frame are provided with two leading arm assemblies 3; a reinforcing beam 16 is welded between a left bracket assembly 18 and a right bracket assembly 14; the upper ends of a left reinforcing plate 17 and a right reinforcing plate 15 are welded with the beam of the frame; the left bracket assembly 18 and the right bracket assembly 14 are connected with the two leading arms 3 by a bolt through an eccentric sleeve 1; the front end of the two leading arms 3 is movably connected with the left bracket assembly 18 and the right bracket assembly 14, and the middle part is fixedly connected with a splint 5 and an axle by the bolt 6; the upper end of a shock absorber 2 is connected with the left bracket assembly 18 and the right bracket assembly 14, and the lower end is connected with the splint 5. With the arrangement, the utility model has good smoothness and stable operation, which can overcome the defect of the insufficient antiroll capability for the common semi-trailer air suspension.
Description
Technical field
The utility model relates to air suspension for trailer.
Background technology
At present, the trailer major part that China produces all adopts steel spring version, and its shortcoming is that ride comfort, poor stability and road pavement are destroyed seriously.Perfect along with laws and regulations, country is more and more stricter to the overload restriction of transport vehicle, and the maintenance of express highway is more and more paid attention to.Under this situation, the trailer that has air suspension progressively becomes the first-selection of logistics company, and this has promoted developing rapidly of trailer air suspension structure.
Common air suspension for trailer is mainly by guide arm and support thereof, air bag and support thereof, and bumper and support thereof are formed, and bearing capacity is mainly born by air bag, and side force is all born by guide arm, and this class formation ride comfort is more satisfactory, but anti-roll capability is general.
Summary of the invention
The purpose of this utility model overcomes above-mentioned problems of the prior art exactly, provides a kind of ride comfort good, the desirable superimposed trailer of anti-roll capability air suspension structure.
For reaching above purpose, the utility model has been taked following technical scheme, the vehicle frame both sides are provided with two guide arm assemblies 3,18,14 welding of left and right bracket assembly, one deep beam 16, left and right brace panel 17,15 upper ends and cross member of frame welding, lower end and left and right bracket assembly 18,14 and deep beam 16 welding; Two guide arm assemblies 3 be respectively charged into left and right bracket assembly 18,14 in open the crotch place, between adopt bearing cap shim to adjust relative gap; Left and right bracket assembly 18,14 and two guide arm assemblies 3 are by eccentric sleeve 1 bolt together, and two guide arm assemblies, 3 front ends and left and right bracket assembly 18,14 flexibly connect, and captive joint with bolt 6 with vehicle bridge with supporting plate 5 in the middle part; Two air bag assemblies 9 are installed to bear vertical load in upper end, shape for hat beam 8 both sides, captive joint with the rear end of both sides guide arm assembly 3 in the lower end; Bumper 2 upper ends are connected with left and right bracket assembly 18,14, and the lower end is connected with supporting plate 5.
The utility model adopts deep beam and left and right brace panel to strengthen between the left and right bracket assembly in both sides, has improved road-holding property, between the guide arm assembly of both sides, vehicle bridge rear, adopts the shape for hat beam to connect simultaneously, has improved the anti-roll capability of car load.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to accompanying drawing 1,2, left and right bracket assembly 18,14 is welded in the vehicle frame both sides, left and right brace panel 17,15 upper ends and cross member of frame weld in both sides, weld with left and right bracket assembly 18,14 respectively the lower end, and deep beam 16 and left and right bracket assembly 18,14 and 17,15 welding of left and right sides brace panel make it become an integral body.
Two guide arm assemblies 3 be respectively charged into left and right bracket assembly 18,14 in open the crotch place, between bearing cap shim 19 be installed respectively adjusted its relative gap; Two stands assembly and guide arm assembly 3 are realized the front and back position adjustment in the installation process by eccentric sleeve 1 bolt together.
Two guide arm assemblies 3 are settled in the vehicle frame both sides, these guide arm assembly 3 front ends and left and right bracket assembly 18,14 bolted connections, and the middle part is by bolt 6 and vehicle bridge bolted connection, and the rear end uses shape for hat beam 8 both sides guide arm assembly 3 captive joints.
The vehicle frame both sides are settled an air bag assembly 9 respectively, and this is captiveed joint with vehicle frame by air bag upper bracket assembly 10 above air bag assembly 9, captives joint with shape for hat beam 8 below.
Two vibration damper assemblies 2 are settled in the vehicle frame both sides, these vibration damper assembly 2 upper ends and left and right bracket assembly 18,14 bolted connections, lower end and supporting plate 5 bolted connections, both sides supporting plate 5 and vehicle bridge welding.
Levelling valve assembly 12 is captiveed joint with levelling valve upper bracket 11, and levelling valve plumbing bar assembly 13 upper ends and levelling valve assembly flexibly connect, and lower end and levelling valve lower bracket 20 flexibly connect, and are arranged in the vehicle bridge mid-plane.
The utlity model has good ride comfort, road-holding property, and can overcome the weakness of common superimposed trailer air suspension anti-roll capability deficiency.
