Description
Technical field:
The utility model relates to off-highway wide dumper technical field, specifically a kind of band limit and carfare adjustment
Wide dumper rear suspension system.
Technical background:
The rear suspension system of wide dumper generallys use leaf spring structure at present, and part of the manufacturer begins trying oil gas hanging
Hanging hang structure, the ipsilateral suspension cylinder of vehicle frame are not connected to by piping connection, the suspension cylinder of vehicle frame two sides；Its suspension cylinder directly uses
Existing oil-gas separated-type suspension cylinder relies on the rigid support limit between vehicle bridge and vehicle frame；This mode has the disadvantage that: 1,
When compression, by rigid limit, ride comfort is poor；2, only one hydraulic fluid port on suspension cylinder, oil liquid generate lateral force when moving, cause
Suspension cylinder eccentric wear；3, the suspension of vehicle frame two sides is completely independent, and in unloading, inclination of vehicle is big, and there are security risks.
Utility model content:
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, the width of a kind of band limit and carfare adjustment is provided
Body dumper rear suspension system；Vehicle frame tilts big, oil gas cylinder and holds when mainly solving poor existing hydro-pneumatic suspension system ride comfort, lifting
The problems such as easy eccentric wear.
The technical solution of the utility model is: the wide dumper rear suspension system of a kind of limit of band and carfare adjustment,
It is characterized in that, is made of suspension cylinder, accumulator, the first damper, the second damper and connecting line；The suspension cylinder
It is mounted between vehicle frame and vehicle bridge, the accumulator, the first damper, the second damper are fixed on vehicle frame；Vehicle frame is ipsilateral
Suspension cylinder pass through piping connection, vehicle frame ipsilateral the first damper and accumulator by piping connection, and with the first damper
Pass through piping connection；First damper of vehicle frame two sides is connected by the second damper of pipeline and central frame beam.
Further, the suspension cylinder is made of seal assembly, cylinder cap, piston rod, cylinder barrel；The seal assembly peace
On cylinder cap, cylinder cap and cylinder barrel are fixed together, and piston rod passes through seal assembly and cylinder cap；It is provided on the piston rod
Three groups of damping holes of even distribution；The cylinder barrel top is provided with equally distributed three groups of damping holes.
The wide dumper rear suspension system and prior art of a kind of band limit and carfare adjustment described in the utility model
Compared to following good effect: 1, when vehicle run, since the damping of the second damper is larger and action time is short, vehicle frame one
The hydraulic oil of side is difficult to be left to the other side；When packing case lifting, since the lifting time is long, the hydraulic oil of vehicle frame two sides can be mutual
Circulation, plays carfare corrective action；2, three groups of damping holes are uniformly distributed on piston rod and cylinder barrel, make suspension cylinder itself that there is limit
Effect；3, the damping hole on piston rod and cylinder barrel is equally distributed, can eliminate lateral force, avoids generating friction phenomenon.
Detailed description of the invention:
Fig. 1 is the systematic schematic diagram of the utility model；
Fig. 2 is the structure chart of the utility model；
Fig. 3 is the A-A cross-sectional view of Fig. 2；
Fig. 4 is the structure chart of the suspension cylinder of the utility model.
Drawing explanation:
1 suspension cylinder, 2 accumulator, 3 first damper, 4 second damper 1-1 seal assembly 1-2 cylinder cap 1-3
Piston rod 1-4 cylinder barrel.
Specific embodiment:
For a better understanding and implementation, providing specific embodiment with reference to the accompanying drawing is described in detail the utility model；Institute
It is served only for explaining the utility model for embodiment, is not intended to limit the scope of the utility model.
Embodiment 1 selects suitable suspension cylinder 1, accumulator 2, first to damp referring to Fig. 1,2,3,4 according to design requirement
Device 3 and the second damper 4；Suspension cylinder 1 is made of seal assembly 1-1, cylinder cap 1-2, piston rod 1-3, cylinder barrel 1-4, by sealing group
Part 1-1 is mounted on cylinder cap 1-2, and cylinder cap 1-2 and cylinder barrel 1-4 are bolted on together, and piston rod 1-3 passes through seal assembly
1-1 and cylinder cap 1-2 forms suspension cylinder 1；Equally distributed three groups of damping holes are provided on piston rod 1-3, while in cylinder barrel 1-4
Top is provided with equally distributed three groups of damping holes；The damping of first damper 3 is c, and the damping of the second damper 4 is 5c；4 are hung
Cylinder 1 is mounted between vehicle frame and vehicle bridge, and 2 accumulators, 2,2 the first dampers, 3,1 the second dampers 4 are fixed on vehicle frame
On；The ipsilateral suspension cylinder 1 of vehicle frame is by piping connection, and with the first damper 3 by piping connection, by vehicle frame it is ipsilateral first
Damper 3 and accumulator 2 pass through piping connection；The first damper 3 of vehicle frame two sides is finally passed through into pipeline and central frame beam
The connection of second damper 4；Form the wide dumper rear suspension system of a kind of limit of band and carfare adjustment of the utility model.
A kind of band of the utility model limits and the wide dumper rear suspension system of carfare adjustment, in vehicle operation,
Since the Vehicular vibration time is short and the damping of the second damper 4 is greater than the first damper 3, the hydraulic oil of vehicle frame side is difficult to pass through
Second damper 4 enters the other side, plays cushioning effect by the up and down motion of accumulator 2, and decay by the first damper 3
Vibration；Suspension cylinder on jackshaft is mounted on to stretch or when compression, by hydraulic oil make the suspension cylinder being mounted on rear axle compress or
It stretches, plays balanced action；
In packing case lifting, since the lifting time is longer, the hydraulic oil of vehicle frame side can be entered by the second damper 4
The pressure of the other side, 4 suspension cylinders 1 is equal, can prevent inclination of vehicle, plays the role of car adjustment；
For vehicle in uneven road surface, front suspension cylinder compression, hydraulic oil enters Rear suspended cylinder, and Rear suspended cylinder stretches；
When suspension cylinder 1 compresses, piston rod 1-3 is moved upwards, and blocks the damping hole on cylinder barrel 1-4 successively, makes to damp
It is gradually increased, piston rod 1-3 is hindered to continue to move；When suspension cylinder 1 stretches, piston rod 1-3 is moved downward, and cylinder cap 1-2 is kept off successively
The firmly damping hole on piston rod 1-3 is gradually increased damping, hinders piston rod 1-3 to continue to move, plays position-limiting action.
