Abstract
The utility model relates to a kind of suspensions of semitrailer leaf spring, belong to trailer technical field, including fore-stock, middle bracket and after-poppet, leaf spring is equipped between fore-stock and middle bracket and between middle bracket and after-poppet, a vehicle bridge is equipped on each leaf spring, middle internal stent is hingedly set by two pin shafts there are two balancing stand, one end of leaf spring is hinged on bracket, the other end of leaf spring is hinged on balancing stand, it is respectively fixed with a coupling bar on the two sides of after-poppet upper end, buffer spring is hingedly equipped between coupling bar and balancing stand.The utility model sets that there are two balancing stands to replace an individual equalizer bar in middle internal stent, and leaf spring each in this way not will receive the impact force that front and back is superimposed, and the rotation amplitude of leaf spring is also smaller, and semitrailer driving is more steady.
Description
Technical field
The utility model relates to a kind of suspensions of semitrailer leaf spring, belong to trailer technical field.
Background technique
Semitrailer in the prior art includes fore-stock, middle bracket and after-poppet, is joined between them using leaf spring
It connects.Middle internal stent is equipped with an equalizer bar, and leaf spring is hinged on the both ends of equalizer bar.In the process of semitrailer walking, when encountering
When larger hollow, especially when travelling fast speed.The front-wheel of rear wheel first passes around hollow, and the leaf spring of front is first subjected to
The front end of impact, equalizer bar tilts, and then the rear-wheel of rear wheel also rapidly passes through hollow, and such equalizer bar is in the very short time
Interior rotation amplitude is very big, and equalizer bar can will receive the impact force that front and back is superimposed in certain moments, with the extension meeting of time
There is very big security risk in the damage for causing equalizer bar.
Utility model content
The purpose of this utility model is to solve that deficiency exists in the prior art, and provides a kind of travel more steadily, more
The semitrailer leaf spring suspension of safety.
The utility model is achieved through the following technical solutions:
That is a kind of semitrailer leaf spring suspension, including fore-stock, middle bracket and after-poppet, between fore-stock and middle bracket with
And leaf spring is equipped between middle bracket and after-poppet, a vehicle bridge is equipped on each leaf spring, middle internal stent passes through two pins
Axis is hingedly set there are two balancing stand, and one end of leaf spring is hinged on bracket, and the other end of leaf spring is hinged on balancing stand, after-poppet
It is respectively fixed with a coupling bar on the two sides of upper end, buffer spring is hingedly equipped between coupling bar and balancing stand.
The utility model middle internal stent set there are two balancing stand replace an individual equalizer bar, leaf spring each in this way
The impact force that front and back is superimposed is not will receive, and the rotation amplitude of leaf spring is also smaller, semitrailer driving is more steady.
Further preferably, the vehicle bridge lower end is fixed with lifting lug assembly, and the nock face of lifting lug assembly is equipped with hinge
Pull rod is hingedly equipped between joint chair, hinged seat and fore-stock, middle bracket.
Further preferably, the front end of the pull rod is higher than rear end, and is 6 degree with the tilt angle of horizontal plane.
Further preferably, wearing plate is equipped with inside the fore-stock, middle bracket and after-poppet.
Compared with prior art, beneficial effect possessed by the utility model is:
The utility model middle internal stent set there are two balancing stand replace an individual equalizer bar, leaf spring each in this way
The impact force that front and back is superimposed is not will receive, and the rotation amplitude of leaf spring is also smaller, semitrailer driving is more steady.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, fore-stock；2, middle bracket；3, after-poppet；4, leaf spring；5, vehicle bridge；6, lifting lug assembly；7, hinged seat；8,
Pull rod；9, balancing stand；10, pin shaft；11, coupling bar；12, buffer spring.
Specific embodiment
Below against attached drawing, specific embodiment of the present utility model is described in further detail.
A kind of semitrailer leaf spring suspension as shown in Figure 1, including fore-stock 1, middle bracket 2 and after-poppet 3, fore-stock 1,
Wearing plate is equipped with inside middle bracket 2 and after-poppet 3, between fore-stock 1 and middle bracket 2 and middle bracket 2 and after-poppet 3 it
Between be equipped with leaf spring 4, be equipped with a vehicle bridge 5 on each leaf spring 4, hingedly set inside middle bracket 2 by two pin shafts there are two
One end of balancing stand 9, leaf spring 4 is hinged on bracket, and the other end of leaf spring 4 is hinged on balancing stand 9, and balancing stand 9 passes through pin shaft
10 are mounted on middle bracket 2, and a coupling bar 11, coupling bar 11 and balance are respectively fixed on the two sides of 3 upper end of after-poppet
Buffer spring 12 is hingedly equipped between frame 9.
5 lower end of vehicle bridge is fixed with lifting lug assembly 6, and the nock face of lifting lug assembly 6 is equipped with hinged seat 7, hinged seat 7
Pull rod 8 is hingedly equipped between fore-stock 1, middle bracket 2, the front end of pull rod 8 is higher than rear end, and the tilt angle with horizontal plane
It is 6 degree.
Working principle:
Using the utility model semitrailer in the process of moving, the stability of wheel is more preferable, between front and back leaf spring 4 individually
Work, does not influence other leaf springs 4, is easily damaged there is no the impact force that middle 2 internal balance joist support of bracket is superimposed yet
Problem.
The orientation or positional relationship of the instructions such as term "inner", "outside", "upper", "lower" is in the description of the present invention,
It is based on the orientation or positional relationship shown in the drawings, is merely for convenience of description the utility model rather than requires the utility model must
It must be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
