Abstract
The utility model provides a suspension before compound for machineshop car driver's cabin, includes leaf spring (1), leaf spring support (3), rotating basis (4) and coil spring (2), leaf spring (1) upper end and coil spring (2) upper end coaxial articulated, bolt and leaf spring support (3) fixed connection are passed through to leaf spring (1) bottom, leaf spring support (3) and rotating basis (4) pass through the bolt and articulate, rotating basis (4) fix on the frame. Under the condition of small displacement of a good road surface, the plate spring (1) only serves as a guide element and does not participate in transduction, and energy is mainly buffered by the spiral spring (2); under the abominable operating mode, after suspension displacement triggers spacing, leaf spring (1) begins to play a role, participates in the kinetic energy buffering together with coil spring (2) to adapt to complicated operating mode.
Description
Technical field
The utility model relates to a kind of front-suspension, it is more specifically to a kind of for engineering vehicle cab it is compound before
Suspension, belongs to automobile technical field.
Background technique
Currently, existing engineering vehicle cab front-suspension majority is using rubber or helical spring as elastic element, foreign countries
Individual vehicles have used leaf spring as elastic element；By the deformation of above-mentioned elastic element, reach the caching effect of vibrational energy.
But since engineering truck operating condition is complicated, not only needed foundation pit even without road under conditions of run at a low speed, but also need to exist
High-speed cruising on paved road, and use single elastic element as energy converter, it is difficult to adapt to above-mentioned complex working condition: 1, rubber
Part rigidity is big, only has flexible connection effect, substantially without buffer capacity；2, rigidity of helical spring is low, vibrates under severe road conditions
Amplitude is big, and stored energy capacitance is small, is easy to produce limit breakdown；3, rigidity of plate spring between it is above-mentioned between the two, be adapted to severe road
Face, but for good road surface, rigidity of plate spring still shows excessive.
Summary of the invention
The purpose of this utility model is that being made for existing engineering vehicle cab front-suspension using single elastic element
The problems such as to be difficult to adapt to complex working condition existing for energy converter, provides a kind of compound front-suspension for engineering vehicle cab.
To achieve the above object, the technical solution of the utility model is: a kind of for the compound of engineering vehicle cab
Type front-suspension, including leaf spring, flat spring bracket, rotating basis and helical spring, the leaf spring upper end and helical spring upper end are same
Axis is hinged, and leaf spring bottom end is fixedly connected by bolt with flat spring bracket, and the flat spring bracket and rotating basis are cut with scissors by bolt
It connects, the rotating basis is fixed on vehicle frame.
Arc chute is machined on the flat spring bracket, the flat spring bracket is by arc chute using bolt and rotation
Turn pedestal connection.
The helical spring lower end is equipped with damper.
Compared with prior art, the beneficial effects of the utility model are:
Overall structure of the present invention is simple, and leaf spring and two kinds of elastic elements of helical spring are compounded in mounting structure, and is led to
The limiting device for crossing arc chute formation is controlled, so that leaf spring is only used as guiding member in the thin tail sheep of good road surface
Part is not involved in transducing, mainly carries out energy snubber by helical spring；Under bad working environments, after suspension is displaced triggering limit, plate
Spring starts to play a role, and kinetic energy buffering is participated in together with helical spring, to adapt to complex working condition.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Fig. 2 is the utility model side view.
In figure: leaf spring 1, helical spring 2, flat spring bracket 3, rotating basis 4, arc chute 5, vehicle frame 6, damper 7, suspension
Upper bracket 8.
Specific embodiment
The utility model is described in further detail below in conjunction with Detailed description of the invention and specific embodiment.
Referring to Fig. 1 to Fig. 2, a kind of compound front-suspension for engineering vehicle cab, including leaf spring 1, flat spring bracket 3,
Rotating basis 4 and helical spring 2.1 upper end of leaf spring and 2 upper end of helical spring is coaxially hinged, and 1 bottom end of leaf spring passes through bolt
It is fixedly connected with flat spring bracket 3, by bolted splice, the rotating basis 4 is solid for the flat spring bracket 3 and rotating basis 4
It is scheduled on vehicle frame.
Referring to Fig. 1 to Fig. 2, arc chute 5 is machined on the flat spring bracket 3, the flat spring bracket 3 passes through circular arc
Sliding slot 5 is connect using bolt with rotating basis 4, i.e., flat spring bracket 3 can pass through the arc chute 5 using bolt and be fixed on rotation
Turn on pedestal 4.It being limited herein using arc chute 5,3 relative rotation pedestal 4 of flat spring bracket can do ± 5 degree of rotary motions,
After surmounting the angle, bolt is by the stuck limit of arc chute 5；So that leaf spring 1 is freely rotatable within a certain angle, only rise
Leading arm effect, is not involved in energy storage.
Referring to Fig. 1 to Fig. 2,2 lower end of helical spring is equipped with damper 7.
Referring to Fig. 1 to Fig. 2, leaf spring 1 and 2 two kinds of elastic elements of helical spring are compounded in mounting structure in the utility model
In, and leaf spring 1 and the compound of helical spring 2 are controlled by the limiting device that arc chute 5 is formed: in good road surface
In the case of thin tail sheep, leaf spring 1 is only used as director element and is not involved in transducing, mainly carries out energy snubber by helical spring 2；Severe
Under operating condition, after suspension is displaced triggering limit, leaf spring 1 starts to play a role, and participates in kinetic energy buffering together with helical spring 2.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, above structure
It all shall be regarded as belonging to the protection scope of the utility model.
