Connected between semiaxis by adapter, make distance H=150~200mm in axle center between supporting axis and left and right semiaxis.
Described cover plate includes steel base and the spacing block rubber on top, and two U-bolts are pressed in the two of steel base
End, spacing block rubber is between two U-bolts.
Leaf spring mounting seat is set at the both ends of supporting axis, by two U-bolts by cover plate 5 and leaf spring and steel plate
Spring mounting seat is fastened on the supporting axis of rear axle.
Damper installation key seat is set on rear axle, damper is arranged on rear axle by bearing pin.
Stabiliser bar mounting seat is set on the adapter at rear axle both ends, stabiliser bar is connected to by connecting pin sets stabiliser bar installation
On seat.
There is wheel rim mounting disc on the semiaxis at rear axle both ends.
The advantages of the utility model：
In the case of vehicle height only 2m, to meet that ordinary people can normally stand erectly walking, rear axle height need to be lowered as far as possible
Degree, to increase interior space.In the utility model, rear axle can be had using supporting axis and the door type structure that falls that left and right semiaxis welds
Outage in the increase of effect, compartment aisle height increase to 1620mm by 1489mm originally；Floor level is reduced, back door is marked time height
Degree is down to 380mm by 511mm originally.The structure type increases interior space, is improved Consumer's Experience.
Be advantageous to the damping of back axle in the utility model using damper, stabiliser bar, the cover plate with spacing block rubber.Protect
The comfortableness of mine anti-explosion trackless rubber-tyred personnel carrier is demonstrate,proved.
Using the few piece variable-section steel sheet spring of symmetrical expression in the utility model, reduced while ensure that rear bridge reliability
Structural member weight, light-weight design are an important factor for ensureing course continuation mileage, ensure that mine anti-explosion trackless rubber-tyred personnel transport
The practicality of car.
U-bolt is used in the utility model by the cover plate with spacing block rubber and leaf spring and the side of rear axis connection
Formula, this screw connection manner is easy to disassemble, ensure that maintainability, while this structure type reliability that is spirally connected is preferable.
When mine anti-explosion trackless rubber-tyred personnel carrier travels in mining area, the staff of carrying usually needs to be equipped with weight
Up to 20kg equipment, low-floor back axle can effectively reduce back door and mark time in the case where ensureing that vehicle length is constant
Highly, interior space is increased, meets the actual use demand of client.Few piece variable cross-section steel plates simultaneously of the present utility model
Spring alleviates complete vehicle weight, adds course continuation mileage, and the cover plate with spacing block rubber serves damping and drop in motion
The effect made an uproar, it ensure that the practicality and security of mine anti-explosion trackless rubber-tyred personnel carrier.
