Abstract
The utility model discloses a kind of driving cab rear suspension assembly, and structure is full symmetric.Mainly it is made of undersetting, spring damper assembly, locking bracket assembly, hydraulic lock assembly, crossbeam.Undersetting and vehicle frame are connected.Spring damper assembly upper end and hydraulic lock assembly are hinged, and lower end is hinged with undersetting.Locking bracket assembly upper end and driver's cabin are connected, and lower end cooperates after driver's cabin drops back into hydraulic lock assembly.Hydraulic lock assembly and undersetting are hinged, can control the motion profile of rear suspension device.Crossbeam and left and right undersetting are connected, and can increase rear suspension device rigidity.There is rubber bushing at locking bracket assembly pin shaft both ends, can make smooth into lock process.There is rubber bushing in the lifting lug of spring damper assembly both ends, can reduce junction abnormal sound.Hydraulic lock assembly and hydraulic cab load lifting cylinder link.The structure have many advantages, such as bearing capacity is strong, damping property is good, it is compact-sized, be easy into lock, comfort in vehicle travel process, safety can be effectively improved.
Description
Technical field
The utility model relates to a kind of automotive accessories, and in particular to the rear-suspending assembly of truck cab.
Background technique
With the development of China Transportation Industry and the progress of science and technology, people require the comfort of heavy truck also more next
It is higher.Main truck domestic at present is all made of the rear suspension device with helical spring or air spring, the structure type
It can decay and be transmitted to the vibration of driver's cabin by vehicle frame, improve the comfort of driver's cabin.But with the accumulative mistake of driver's cabin component
Difference, locking bracket enters situations such as lock is difficult during falling after rise there are still driver's cabin, may jeopardize traffic safety.
Summary of the invention
In order to improve the comfort stability of driver's cabin, improves locking bracket during driver's cabin is fallen after rise and enter to lock the feelings such as difficulty
Condition, the utility model provide a kind of driving cab rear suspension assembly.
Specific embodiment is as follows: a kind of driving cab rear suspension assembly, its own structure is full symmetric, mainly by lower branch
Seat, spring damper assembly, locking bracket assembly, hydraulic lock assembly, crossbeam composition.Undersetting is solid by bolt and nut and vehicle frame
Even.Spring damper assembly upper end is hinged by bolt and nut and hydraulic lock assembly, and lower end is cut with scissors by bolt and nut and undersetting
It connects.Locking bracket assembly upper end is connected by bolt and nut and driver's cabin, and lower end is matched after driver's cabin drops back into hydraulic lock assembly
It closes.Hydraulic lock assembly is hinged by bolt and nut and undersetting.Crossbeam is connected by bolt and nut and left and right undersetting.
Another preferred embodiment of the utility model: hydraulic lock assembly one end and undersetting are hinged, it can be achieved that wobbling action, control
The motion profile of rear suspension device processed improves the stability of cab motions.
Another preferred embodiment of the utility model: there are rubber bushing, the change of rubber bushing in locking bracket assembly pin shaft both ends
Shape can offset the cumulative errors of suspending apparatus and driver's cabin, and locking bracket is made smoothly to enter lock.
Another preferred embodiment of the utility model: crossbeam and two sides undersetting are connected, connection at left and right sides of rear suspension device
For an entirety, increase rear suspension device rigidity.
Another preferred embodiment of the utility model: there is rubber bushing in the lifting lug of spring damper assembly both ends, can offset
The deformation of lifting lug axial direction, hinged place, which is flexible coupling, can reduce junction abnormal sound.
Another preferred embodiment of the utility model: hydraulic lock assembly and hydraulic cab load lifting cylinder oil communication, and have liquid
Locking conjunction state signal wire is pressed, hydraulic lock can link openings when driver's cab turnover, if having hydraulic lock patent when driver's cabin falling
Lock can export alarm signal, improve safety.
The utility model structure is simple, components reliable operation, saves space, the service life is long, and stability is good, bearing capacity
By force, the vibrational energy that all directions that can decay transmit is easy to have good comfort, safety into lock.
Detailed description of the invention
Figure of description is the utility model attachment structure schematic diagram
Wherein 1 undersetting, 2 spring damper assemblies, 3 hydraulic lock assemblies, 4 locking bracket assemblies, 5 crossbeams, 6 bolts one, 7
Nut one, 8 bolts two, 9 nuts two, 10 bolts three, 11 nuts three.
Specific embodiment
As shown in Figure of description, it is full symmetric that the cabin front suspension sets assembly tiled configuration.Undersetting (1) passes through spiral shell
Bolt nut and vehicle frame are connected.It is cut with scissors by bolt two (6) nut two (7) and hydraulic lock assembly (3) spring damper assembly (2) upper end
It connects, lower end is hinged by bolt three (10) nut three (11) and undersetting (1).Locking bracket assembly (4) upper end passes through bolt spiral shell
Female to be connected with driver's cabin, lower end cooperates after driver's cabin drops back into hydraulic lock assembly (3).Hydraulic lock assembly (3) passes through bolt one
(6) nut one (7) and undersetting (1) are hinged.Crossbeam (5) is connected by bolt one (6) nut one (7) and left and right undersetting (1).
Claims (4)
1. a kind of driving cab rear suspension assembly, it is characterised in that left and right structure is full symmetric；Its left side structure are as follows: undersetting (1)
It is connected by bolt and nut and vehicle frame, spring damper assembly (2) upper end is total by bolt two (8) nut two (9) and hydraulic lock
Hingedly at (3), lower end passes through bolt three (10) nut three (11) and undersetting (1) hingedly, and locking bracket assembly (4) upper end passes through
Bolt and nut and driver's cabin are connected, and lower end cooperates after driver's cabin drops back into hydraulic lock assembly (3), and hydraulic lock assembly (3) passes through
Hingedly, crossbeam (5) passes through bolt one (6) nut one (7) and left and right undersetting for bolt one (6) nut one (7) and undersetting (1)
(1) it is connected.
