Benefit discloses a kind of automobile engine rod-pulling type rear suspension structure: " including the small end bushing group cooperated with shaft skeleton one end
Part；Shaft skeleton the other end is hollow shaft, middle part equipped with a fabrication hole；The middle part of one major part skeleton is equipped with partition；Two
The rubber spring that the identical middle part of a structure is equipped with via hole is symmetrically disposed in the two sides of major part skeleton partition；Major part skeleton and its
The rubber spring of partition two sides and the hollow shaft of shaft skeleton the other end cooperate；One hollow axle bolt passes through in the middle part of big epicranial plate
Via hole, shaft skeleton the hollow shaft of the other end be cooperatively connected with the nut for being located in the middle part of shaft skeleton in fabrication hole." evidence
The patent document introduction, it " can effectively avoid the stress of rubber from concentrating, prevent fatigue cracking, improve the reliability of suspension；It is real
Individually changeing for suspending rubber mainspring part is showed；When rubber spring breaks down, can only replacement rubber part be changed without
Remaining part, to reduce maintenance cost." as described in the patent document, basic structure is rubber spring.Although but it can
Maintenance cost is reduced, does not solve the problems, such as existing rear-suspending pull rod at all but.In fact, pendulum model suspension system is arranged, after
Suspending Tiebar structure is important spare part, and existing rear-suspending pull rod uses pure rubber or hydraulic bushing structure substantially, when idling,
Because it has certain rigidity, become vibration transfer path, cause NVH bad, when large torque, non-linear rigidity is by its rubber material institute
Limit, non-linear rigidity excessively under, the displacement of power assembly cannot be entirely limited, and often big displacement load fatigue effect is poor.
Summary of the invention
Main inventive purpose of the invention, be to provide a kind of new rear-suspending pull rod with solve it is existing using pure rubber or
Some problems brought by the rear-suspending pull rod of hydraulic bushing structure.
Technical solution used in the present invention is: a kind of automobile engine rear suspension pull rod, including pressure cylinder, piston rod, work
Plug, pressure cylinder are front and back trend, and pressure cylinder is interior filled with inert gas or gas mixture.The rear end of pressure cylinder and with automobile send out
The middle part for the gear box that motivation is connected together is connected.Piston is connected with pressure cylinder sliding, and piston rod rear end and piston are solid
Even, the front end of piston rod is connected with fore sub frame.
The present invention is using after using the gas spring that pressure cylinder, piston rod, piston are formed as main member as automobile engine
Pull rod is suspended, has several advantages that 1. can be solved perfectly idling rear-suspending and hang the excessive problem of acceleration, to mention
Height improves vehicle NVH impression；2. the too small problem of rear-suspending non-linear rigidity can be solved perfectly, to optimize vehicle NVH；
3. and then can be solved perfectly that torquey engine rear-suspending pull rod is durable to ask because its non-linear rigidity can be designed to very big
Topic.Therefore, the present invention is a very outstanding technology.
Preferably, the rear end of pressure cylinder and connecting bracket are connected, the cross section main body of connecting bracket is in U-shape, U-shaped
The free end on arranged on left and right sides side is bent to the left, to the right respectively, and the rear end of pressure cylinder passes through the two bending parts and gear box
The lower end at middle part be fixed together.Further preferably, two bending parts are all provided with there are two through-hole, and the rear end of pressure cylinder passes through
The two bending parts are fixed together using the lower end at the middle part of bolt arrangement and gear box.This preferred embodiment, structure letter
Single, processing and manufacturing is easy, easy for installation.
Preferably, the front end of piston rod is connected with fore sub frame lower end.
Preferably, the front end of piston rod is equipped with hinge bush, the front end of piston rod passes through hinge bush and fore sub frame
It is connected.This preferred embodiment, simple and reasonable, connection installation is easy.
In conclusion the beneficial effects of the present invention are: overall structure advantages of simple of the present invention, connection installation are easy, have
Following advantage: 1., which can be solved perfectly idling rear-suspending, hangs the excessive problem of acceleration, improves vehicle NVH to improve
Impression；2. the too small problem of rear-suspending non-linear rigidity can be solved perfectly, to optimize vehicle NVH；3. because its is non-linear
Rigidity can be designed to very greatly, and then the durable problem of torquey engine rear-suspending pull rod can be solved perfectly.Therefore, of the invention
It is a very outstanding technology.
