Embodiment
As shown in Figure 1, heavy-duty vehicle driver's cab turnover supporting mechanism described in the present embodiment, the supporting mechanism setting is being driven
It sails between room 10 and stringer 20, the supporting mechanism includes: pedestal 30, hydraulic stem, first support bar 50 and second support bar
60；The pedestal 30 is fixed at stringer 20 and is provided with telescopic cavity 31 in 10 side of driver's cabin, the pedestal 30, described
Limit hole 32 is provided on the upside of pedestal 30；The hydraulic stem is arranged in telescopic cavity 31, and along the direction of stringer 20 to driver's cabin
10 fronts are flexible；The hydraulic stem includes: often to go out portion 41, pars contractilis 42 and fixed part 43, and described often portion 41 is arranged always out
Outside fixed part 43, the pars contractilis 42 is extend out to outside fixed part 43 with the elongation of hydraulic stem, is retracted with contraction of hydraulic pressure bar
To fixed part 43；The first support bar 50 uses stretching structure；Described 50 one end of first support bar and normal portion 41 out are separate
42 one end of pars contractilis is hinged, and the other end is hinged along direction of advance side with driver's cabin 10, and the first support bar 50 is used to support
Driver's cabin 10 prevents from toppling in its forward vehicle direction of advance；Described 60 one end of second support bar passes through limit hole 32 and often goes out portion
41 is hinged close to 42 one end of pars contractilis, and the other end and 10 bottom side of driver's cabin are hinged；The second support bar 60 is used to support driving
Room 10 prevents it from toppling over backward.
In the work of vehicle turnover mechanism, driver's cabin 10 is started turning, while opening supporting mechanism, by hydraulic stem to vehicle
Forward direction motion drives first support bar 50 to play a supporting role with second support bar 60 to driver's cabin 10, prevent its
It dumps forward when operation or topples over backward, cause casualties and vehicle damage；First support bar 50 and second support bar simultaneously
60 can assist the turnover mechanism of vehicle, provide power when overturning to driver's cabin 10, because overturn in driver's cabin 10
Early period, torque is maximum, and turnover mechanism needs very big power that could rotate driver's cabin 10, and at this time hydraulic stem drives first
Strut 50 and second support bar 60 can play the role of assisting overturning well；First support bar 50 and 60 phase of second support bar
Cooperation can support driver's cabin 10 and not topple over, and a certain support rod when something goes wrong, another support rod still is able to prop up
Driver's cabin 10 is propped up or held, prevents it from toppling over.
As shown in figure 4, the supporting mechanism is provided with two groups, it is separately positioned on the two sides of 10 bottom of driver's cabin；Two groups of branch
Support mechanism can be supported 10 two sides of driver's cabin, guarantee stress equalization, prevent long-time discontinuity from leading to driver's cabin
10 deformations；Simultaneously two groups of supporting mechanisms can wherein one group still be able to work when something goes wrong, improve safety.
As shown in Figure 1 and Figure 2, the normal portion 41 out is fixedly installed limited block 44, the limit close to 42 one end of pars contractilis
Block 44 passes through limit hole 32 and second support bar 60 is hinged；Hydraulic stem excess shrinkage is prevented, hydraulic stem is damaged.
Length of the limit hole 32 in vehicle forward direction is equal to hydraulic stem 30 during driver's cabin 10 is overturn in place
Elongated distance prevent hydraulic stem from excessively extending, cause 50 support degree of first support bar to decline, and hydraulic stem can be protected not
It can be damaged because excessively extending.
As shown in figure 3,10 bottom of driver's cabin is arranged fluted 11, it is provided with link block 12 in the groove, it is described
Link block 11 is connect with groove 11 by spring, and the second support bar 60 is connect with link block 11；So that second support bar 60
It is elastic connection between driver's cabin 10, avoids driver's cabin 10 and second support bar 60 in 10 switching process of driver's cabin vibrated
Greatly, unnecessary damage is caused to driver's cabin 10 and second support bar 60.
