Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the schematic diagram that piston rod departs from from piston body；
Wherein, 1- cylinder barrels, 2- piston bodies, 3- piston rods, 4- buckles part, 5- jump rings.
Embodiment
Describe optimal technical scheme of the present utility model in detail below in conjunction with the accompanying drawings.
A kind of truck cap overturns hydraulic cylinder structure, mainly solves commercial truck driver's cab turnover hydraulic cylinder in commercialization
The problem of hindering driver's cabin to move backward in car collision process causes occupant's living space to diminish, it is therefore an objective to which exploitation one kind both met
Driver's cab turnover function, and can have the hydraulic cylinder of crumple function in collision；
Hydraulic cylinder upper and lower cavity in truck normally travel has hydraulic oil, Normal hydraulic cylinder in collision while still alive stopper rod by
Pulling force, due to the Incoercibility of liquid, hydraulic cylinder can not extend.This novel hydraulic cylinder is in driver's cabin collision when stopper rod while still alive
When stress reaches certain force, hydraulic cylinder piston body is departed from piston rod, realize that hydraulic cylinder upper and lower cavity connects, piston rod can be realized
Freely activity, hydraulic cylinder move after no longer hindering entirety of the driver's cabin in collision process, are effectively ensured and realize that occupant's existence is empty
Between；
A kind of truck cap upset hydraulic cylinder structure of the utility model, including the cylinder barrel 1 being connected on automobile chassis, institute
Stating in cylinder barrel 1 has piston portion, and the piston portion is divided into piston body 2 and piston rod 3, and one end of the piston rod 3 is run through
Piston body 2 it is centrally disposed, the piston body 2 and piston rod 3 are fitted close, and the piston rod 3 connects the end head of piston body 2
The buckle part 4 for piston rod 3 to be fixed on to piston body 2 is provided with point, the other end of the piston rod 3 is connected to driving
Room bottom.
Jump ring 5 is additionally provided with the buckle part 4.
The cylinder barrel 1, which is connected to the position of automobile chassis the position of cab bottom is connected to compared to piston rod 3, more to be leaned on
Near-car head.
New invention hydraulic cylinder is realized outside the normal lifting function of Normal hydraulic cylinder by the control of physical dimension, also with
Lower function：1st, when commercial truck is collided, under certain pulling force effect, piston body 2 separates stopper rod with piston rod 3 while still alive, piston rod 3
Free movement, hydraulic cylinder move after no longer hindering entirety of the driver's cabin in collision process, are effectively ensured and realize that occupant's existence is empty
Between；2. the corresponding force value that can also be separated by piston fixed position thickness direction size Control piston to piston rod, it is ensured that living
Stopper rod departs from when colliding generation with piston, ensure that the reliability of normal use.
Such as Fig. 1 or Fig. 2, when when hydraulic cylinder collides, piston rod 3 is by instantaneous pulling force, the liquid of hydraulic cylinder rod chamber by
Compression, because liquid is incompressible, external force is all acted on the piston body 2 of hydraulic cylinder, and piston body 2 transfers force to fixed
On buckle part 4, buckle part 4 is fixed on piston rod 3 by jump ring 5.So that the end of rear end piston rod 3 of fixed circlip 5
By shearing force.By controlling the fixed position thickness direction size of piston body 2 piston body 2 is reached corresponding force value in stress
When the cut-out of piston body 2 fixed position, i.e., when the shear stress at this position is more than allowable stress, broken from this position.Now liquid
Pressure cylinder piston body 2, buckle part 4, jump ring 5 depart from from piston rod 3（Referring to accompanying drawing 2）.Hydraulic cylinder rod chamber and cavity of resorption communicate, oil
Liquid phase is led to.Now, because piston body 2 has disengaged from piston rod 3, the energy free movement of piston rod 3, will be hindered to make without any in collision
With.Piston rod 3 by external force be less than collision stress when, hydraulic cylinder can normal work, do not influenceing hydraulic turnover mechanism just
Often use.
It is described above, the only preferable embodiment of the application, but the protection domain of the application is not limited thereto,
Any one skilled in the art is in the technical scope that the application discloses, the change or replacement that can readily occur in,
It should all cover within the protection domain of the application.Therefore, the protection domain of the application should be with scope of the claims
It is defined.
