Abstract
The utility model discloses a cab back suspension device, the complete symmetry of its structure. Mainly constitute by lock chamber support assembly, crossbeam, hydraulic pressure lock, spring vibroshock assembly, a left side (the right side) undersetting etc. The lock chamber support assembly links firmly with the driver's cabin, and a left side (the right side) undersetting links firmly with the frame. The utility model discloses a left side (the right side) undersetting lower extreme is articulated with spring vibroshock assembly lower extreme, and the upper end is articulated with the hydraulic pressure lock. Lock to articulated with hydraulic pressure spring vibroshock assembly upper end, can attenuate vertically and the side direction vibration to have inside limit structure, can restrict entire system's displacement. Crossbeam and a left side (the right side) undersetting upper portion have strengthened the lateral stability of back suspension to linking firmly. The driver's cabin upset falls the back after rise forms back suspension assembly with all the other parts cooperations. The total has simple structure, stable in structure, the atress is reasonable, the good and upset that can carry out the driver's cabin smoothly of vibration damping with the advantage such as fall back.
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, and this version effectively can decay and is delivered to the vibration of operator's compartment by vehicle frame, improves the traveling comfort of operator's compartment.
Summary of the invention
In order to improve traveling comfort, the stability of operator's compartment, the utility model provides a kind of cab rear suspender.
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, jounce bumper assembly, a left side (right side) undersetting etc.Lock bracket assembly connects operator's compartment and coordinates with hydraulic lock.Hydraulic lock is hinged with left (right side) undersetting by bolt and nut.Jounce bumper assembly two ends are all with rubber bush, and top and bottom use bolt and nut and hydraulic lock and left (right side) undersetting hinged respectively.Crossbeam is fixed by bolt and left (right side) undersetting.Left (right side) undersetting bolt and nut is fixed on vehicle frame.
Another optimal way of the present utility model: rear overhang lock bracket assembly coordinates with hydraulic lock after operator's compartment falls back.Rear-suspending system hydraulic lock normality is lockup state, carrys out locking operator's compartment, prevent it from overturning in vehicle travel process by hydraulic lock.When giving hydraulic lock fuel feeding, hydraulic lock can realize the upset of operator's compartment after opening.Hydraulic lock coordinates with the bearing pin in lock bracket assembly simultaneously, also has the function of transmitted load.
Another optimal way of the present utility model: crossbeam is fixed into as a whole by left (right side) undersetting and vehicle frame, and the rigidity by vehicle frame improves the resistance to bending of rear-suspending system.
Another optimal way of the present utility model: hydraulic lock by bolt and nut with left (right side) undersetting to hinged.When cab load change or bob, hydraulic lock will swing around hinge-point, enhance the lateral stability of system.
Another optimal way of the present utility model: there is polysulphide rubbers the bearing pin inside coordinated with hydraulic lock in lock bracket assembly.Certain distortion can be absorbed, reduce the relative wear between bearing pin and hydraulic lock.
Accompanying drawing explanation
Figure of description is the utility model connection structure schematic diagram
Wherein bottom right bearing 1, lower-left bearing 2, jounce bumper assembly 3, hydraulic lock 4, lock bracket assembly 5, bolt 1, nut 1, crossbeam 8, bolt 29, nut 2 10, bolt 3 11, nut 3 12, bolt 4 13, nut 4 14.
Detailed description of the invention
As shown in Figure of description, described cab rear suspender structure full symmetric, for left side, lock bracket assembly 5 coordinates with hydraulic lock 4 after operator's compartment falls back.Hydraulic lock 4 is hinged by bolt 1 nut 1 and lower-left bearing 2.Spring damper assembly 3 upper and lower side is hinged with nut 4 14 and hydraulic lock 4 and lower-left bearing 2 respectively by bolt 3 11 nut 3 12 and bolt 4 13.Crossbeam 8 is connected with lower-left bearing 2 mutually by bolt 29 nut 2 10.Lower-left bearing 2 is connected by bolt and nut and vehicle frame.
