Description
Technical field
The utility model relates to a kind of suspension system, especially a kind of steering drive axle compound suspension frame system.
Background technology
At present, the vibration damping mode for the suspension system of Medium or severe type cross country car mainly contains leaf spring, air bellow, hydro-pneumatic spring etc.Vehicle is under different Loading conditions, although leaf spring structure is simple, because of its stiffness tuning difficulty, and offset frequency identical under being difficult to realize different Loading conditions.And air bellow, hydro-pneumatic spring although can to realize rigidity adjustable, under can realizing different Loading conditions, offset frequency is identical, because its guiding mechanism is complicated, unfavorable to arrangement.Meanwhile, because air bellow and hydro-pneumatic spring all work under high pressure operating mode, require very high to motion seal part, under cross-country operating mode, compared with leaf spring, reliability reduces a lot.
Utility model content
The utility model provides a kind of steering drive axle compound suspension frame system, makes vehicle under any operating mode, realize vibration insulating system rigidity adjustable, thus offset frequency identical under realizing any operating mode.Meanwhile, simplify guiding mechanism, improve the reliability of suspension system.
Specifically, steering drive axle compound suspension frame system described in the utility model, there is vehicle frame 1, crossbeam 2, leaf spring 3 and flat spring bracket 4, leaf spring 3 two ends are fixedly connected with vehicle frame 1 by flat spring bracket 4, leaf spring 3 stage casing is provided with saddle clamp 5, and by saddle clamp 5 by fastening to leaf spring 3 and crossbeam 2, also include hydro-pneumatic spring 6, hydro-pneumatic spring upper bracket 61 and hydro-pneumatic spring lower bracket 62; Hydro-pneumatic spring 6 upper end is fixedly connected with hydro-pneumatic spring upper bracket 61, and hydro-pneumatic spring 6 lower end is fixedly connected with hydro-pneumatic spring lower bracket 62; Hydro-pneumatic spring upper bracket 61 is fixedly connected on vehicle frame 1, and hydro-pneumatic spring lower bracket 62 is fixedly connected on crossbeam 2.By mounting means hydro-pneumatic spring 6 and leaf spring 3 are arranged in parallel, make leaf spring 3 bear a part of load in whole process, reduce the load of hydro-pneumatic spring 6.Meanwhile, under this kind of set-up mode, leaf spring 3 doublely can make guiding mechanism, thus can save the guiding mechanism in conventional suspension systems, reaches the object of simplied system structure.
In the present embodiment, be provided with bearing pin 7 between hydro-pneumatic spring 6 upper end and hydro-pneumatic spring upper bracket 61, hydro-pneumatic spring 6 upper end and hydro-pneumatic spring upper bracket 61 are by bearing pin 7 pivot joint.By rotatable articulated manner, hydro-pneumatic spring 6 is connected with hydro-pneumatic spring upper bracket 61, to increase loading angle during hydro-pneumatic spring 6 pressurized, improves the Applicable scope of product.

Detailed description of the invention
Below in conjunction with embodiment and respective drawings, the technical solution of the utility model is described in detail, to enable those skilled in the art's understanding clearly scheme of the present utility model, but does not therefore limit protection domain of the present utility model.
The utility model provides a kind of steering drive axle compound suspension frame system, makes vehicle under any operating mode, realize vibration insulating system rigidity adjustable, thus offset frequency identical under realizing any operating mode.Meanwhile, simplify guiding mechanism, improve the reliability of suspension system.
Specifically, steering drive axle compound suspension frame system described in the utility model, there is vehicle frame 1, crossbeam 2, leaf spring 3 and flat spring bracket 4, leaf spring 3 two ends are fixedly connected with vehicle frame 1 by flat spring bracket 4, leaf spring 3 stage casing is provided with saddle clamp 5, and by saddle clamp 5 by fastening to leaf spring 3 and crossbeam 2, also include hydro-pneumatic spring 6, hydro-pneumatic spring upper bracket 61 and hydro-pneumatic spring lower bracket 62; Hydro-pneumatic spring 6 upper end is fixedly connected with hydro-pneumatic spring upper bracket 61, and hydro-pneumatic spring 6 lower end is fixedly connected with hydro-pneumatic spring lower bracket 62; Hydro-pneumatic spring upper bracket 61 is fixedly connected on vehicle frame 1, and hydro-pneumatic spring lower bracket 62 is fixedly connected on crossbeam 2.By mounting means hydro-pneumatic spring 6 and leaf spring 3 are arranged in parallel, make leaf spring 3 bear a part of load in whole process, reduce the load of hydro-pneumatic spring 6.Meanwhile, under this kind of set-up mode, leaf spring 3 doublely can make guiding mechanism, thus can save the guiding mechanism in conventional suspension systems, reaches the object of simplied system structure.
In the present embodiment, be provided with bearing pin 7 between hydro-pneumatic spring 6 upper end and hydro-pneumatic spring upper bracket 61, hydro-pneumatic spring 6 upper end and hydro-pneumatic spring upper bracket 61 are by bearing pin 7 pivot joint.By rotatable articulated manner, hydro-pneumatic spring 6 is connected with hydro-pneumatic spring upper bracket 61, to increase loading angle during hydro-pneumatic spring 6 pressurized, improves the Applicable scope of product.
Below be only that preferred implementation of the present utility model is described; the technical solution of the utility model is not limited to this; the any known distortion that those skilled in the art do on the basis that major technique of the present utility model is conceived all belongs to the claimed technology category of the utility model, and the concrete protection domain of the utility model is as the criterion with the record of claims.
