The utility model content
To be solved in the utility model is the poor technical matters of power suspensioning system damping effect of present tritruck, thereby improves the traveling comfort of car, also can improve the efficient of assembling and maintenance simultaneously.
In order to solve the problems of the technologies described above, the utility model provides a kind of power suspensioning system for tritruck, comprise that engine suspension and change-speed box hang, engine suspension and change-speed box hang and are integrated design, comprise front suspension, middle suspension and rear suspension, captive joint by left and right pipe link in the both sides, lower end of front suspension, middle suspension and rear suspension, be provided with front rail between the left and right pipe link of front suspension and middle suspension, be provided with rear transverse rod between the left and right pipe link of middle suspension and rear suspension; Front of the engine is arranged on the front suspension lower end, and the driving engine rear end is arranged on front rail; The change-speed box front end is arranged on rear transverse rod; The change-speed box rear end is arranged on the rear suspension lower end; Front suspension, middle suspension are connected the upper end and are respectively arranged with the connection shock-absorbing sleeve with rear suspension, described connection shock-absorbing sleeve is connected with tricycle frame respectively.
In technique scheme, because hanging, engine suspension, change-speed box be integrated design, reduced the program of installing and keeping in repair, be conducive to improve assembling and maintenance efficiency; In addition, due to whole suspension, comprised front suspension, middle suspension and rear suspension, their upper end is respectively arranged with the connection shock-absorbing sleeve, connects shock-absorbing sleeve and is connected with tricycle frame respectively, like this, be equivalent to form three groups of dampings, reduced on the one hand the vibrations of driving engine self, also reduced in addition the vibrations when engine output shaft passes to change-speed box, vibrations when simultaneously, also having reduced transmission output shaft output; For in the idling situation, only have the vibrations of driving engine, at this moment, the vibrations of driving engine are carried out repeatedly damping by three groups of damping fulcrums respectively, and damping effect is more obvious.
Further limit, be provided with the cushion blocking mounting hole on described rear transverse rod, described change-speed box front end is connected with rear transverse rod by cushion blocking, such structure can suitably be adjusted the height of the corresponding driving engine outgoing position of change-speed box on the one hand, the vibrations in the time of also further guaranteeing on the other hand to alleviate the change-speed box vibrations.
Same reason, further limit, be provided with the cushion blocking mounting hole on described rear suspension lower end, described change-speed box rear end is connected with the rear suspension lower end by cushion blocking, such structure can suitably be adjusted the height of the corresponding engine power output shaft of change-speed box position on the one hand, the vibrations in the time of also further guaranteeing on the other hand to alleviate the change-speed box vibrations.。
Further, limiting described connection shock-absorbing sleeve is eccentric bushing, eccentric bushing comprises outer sleeve body, eccentric shaft sleeve pipe, top snubber block and bottom snubber block, wherein, the eccentric shaft sleeve pipe is positioned at outer sleeve body inside, and excentric sleeve tube hub line is lower than the outer sleeve body position of center line, and the top snubber block has been filled the space on eccentric shaft sleeve pipe and outer sleeve body top, the bottom snubber block has been filled the space of eccentric shaft sleeve pipe and outer sleeve body bottom, connects shock-absorbing sleeve and passes the eccentric shaft sleeve pipe by bearing pin and be connected with tricycle frame.Adopt, the connection shock-absorbing sleeve of this structure, top snubber block, bottom damping block size can be set according to the total weight adjustment of driving engine and suspension, play one and make in advance the balance of connection shock-absorbing sleeve under the static weight state, guarantee in the situation that dynamic shock load, the elastic pressure that eccentric shaft sleeve pipe surrounding is born is consistent, further, improves the effect of damping.Relatively originally, the sort of axle sleeve is arranged on the outer sleeve body center, top snubber block, bottom snubber block unanimously are the snubber block of semi-circular shape, top snubber block originally is when static weight, own wt due to driving engine and suspension, formed compressive deformation, when dynamic shock load, its damping effect can not produce a desired effect, adopt the connection shock-absorbing sleeve of the technical program, can improve the traveling comfort of the middle vehicle body that travels.
