Abstract
The utility model discloses a suspension device behind parallelly connected spring driver's cabin, the complete symmetry of its structure. Mainly constitute by lock chamber support assembly, crossbeam, hydraulic pressure lock, hydraulic pressure lock support, drag link assembly, spring cushion assembly, stand etc. The lock chamber support assembly links firmly with the driver's cabin, and the stand links firmly with the frame. The crossbeam can increase the transverse rigidity of back suspension. Four spring cushion assemblies ability effective attenuation was transmitted the driver's cabin by the frame vibrations that the slope was arranged to bear the driver's cabin of bigger weight, it is inside to have limit structure, displacement in the time of restricting the entire system motion. The drag link assembly can increase the lateral stability of back suspension. Four hydraulic pressure are locked the in -process driver's cabin of can effectively guaranteeing to drive a vehicle and are closed with back suspension active junction. It is strong that this structure has a bearing capacity, and the damping property is good, and compact structure, stability advantage such as good can effectively improve the travelling comfort among the driving motor vehicles.
Description
Technical field
The utility model relates to a kind of automotive accessory, is specifically related to the rear suspension device of truck cab.
Background technology
Along with the development of China Transportation Industry and the progress of science and technology, people require also more and more higher to the traveling comfort of autotruck.Current domestic main autotruck all adopts the rear suspension device with coil spring or air bellow, effectively can improve the traveling comfort of operator's compartment.But due to coil spring and air bellow self-bearing capacity limited, and be subject to the restriction of existing structure form, existing driving cab rear suspension load-carrying capacity is limited, can not meet the vibration damping needs of the larger special purpose autotruck of some operator's compartment weight for operator's compartment.
Summary of the invention
In order to solve the less problem of existing driving cab rear suspension load-carrying capacity, the utility model provides a kind of can meet the cab rear suspender of special purpose autotruck for heavy Vibration damping of the driver's cab demand.
Specific embodiments is as follows: a kind of cab rear suspender, himself structure full symmetric, is made up of respectively lock bracket assembly, crossbeam, hydraulic lock, hydraulic lock support, tie rod assembly, jounce bumper assembly, column etc.Rear overhang lock bracket assembly connects operator's compartment and coordinates with hydraulic lock.Two, every side hydraulic lock hydraulic lock support is fixed.Jounce bumper assembly two ends all with rubber bush, lower end by bolt and nut and column hinged, upper end and hydraulic lock support hinged.Two ends are all connected with column with hydraulic lock support by bolt and nut with the tie rod assembly of rubber bush.Crossbeam and column bolt are connected.Column bolt and nut is connected on vehicle frame.
Another optimal way of the present utility model: two columns are connected with vehicle frame by bolt, is used for transmitted load.Crossbeam is connected as a whole by column and vehicle frame, by the rigidity of vehicle frame, substantially increases resistance to bending.
Another optimal way of the present utility model: hydraulic lock normality locking, limits the upset of operator's compartment; When to operator's compartment lock fuel feeding, lock is opened, and operator's compartment just can overturn.Left and right has respectively been arranged side by side two hydraulic lock, can bear larger cab load, and it is effectively locked to ensure to heavy operator's compartment in normal driving process.
Another optimal way of the present utility model: lock bracket assembly has two hydraulic lock bearing pins, matches with two hydraulic lock of every side respectively.
Another optimal way of the present utility model: hydraulic lock support is connected by two hydraulic lock of bolt and nut and every side, and by bolt and nut and two spring damper assemblies hinged, enhance the stability of structure.
Another optimal way of the present utility model: two spring damper assemblies that left and right is respectively arranged side by side can bear larger load.Jounce bumper assembly two ends all with rubber bush, lower end by bolt and column hinged, upper end and hydraulic lock support hinged.
Another optimal way of the present utility model: tie rod assembly is hinged with hydraulic lock support and column respectively by bolt and nut, the motion total to jounce bumper serves the effect of guiding, ensure that the lateral stability of structure.
The utility model structure is simple, parts reliable operation, and save space, the life-span is long, good stability, and load-carrying capacity is strong, the vibrational energy that all directions that can decay transmit, and has limit function, has good traveling comfort.
Detailed description of the invention
As shown in Figure of description, described cab rear suspender structure full symmetric, lock bracket assembly 6 coordinates with hydraulic lock 5 after operator's compartment falls back.Hydraulic lock 5 is fixed on hydraulic lock support 4 by bolt 9 nut 10.Spring damper assembly upper and lower side is hinged with hydraulic lock support and column respectively by bolt 11 nut 12 and bolt 13.Tie rod assembly 3 is hinged with hydraulic lock support and column respectively by bolt 11, nut 12.Crossbeam is connected by bolt 8 and two heel posts.Left and right sides column 1 is connected by bolt and nut and vehicle frame.
