Description
Technical field
The utility model relates to automotive field, is specifically related to a kind of automobile front suspension front plate spring supporting structure that is applicable to the low floor operator's compartment, and this structure is specially adapted to the urban sanitation special vehicle.
Background technology
The present domestic truck chassis overwhelming majority is three grades and marks time, higher floor causes chaufeur extremely inconvenient when getting on or off the bus, many chaufeurs certain influence is arranged for the personal safety of chaufeur, and high floor are not good enough on the overall appearance effect when getting off or even beast.
For solving chaufeur inconvenient problem when getting on or off the bus, in some vehicles such as the urban sanitation special vehicle in when design, taked the structure of low floor operator's compartment, be that its body frame structure for automotive adopts the vehicle frame that is positioned at under-cab to be lower than the low early and high after step-by-step construction front/rear frame structure that is of rear portion vehicle frame, and the two sections left-right longerons in front and back that form vehicle frame are fixed together in the mode of overlap joint up and down at joint.
For satisfying the suspension safe reliability of operator's compartment low floor structure vehicle, and the requirement of ride comfort and road-holding property, need a kind of automobile front suspension front plate spring supporting structure that is applicable to the operator's compartment low floor of design, so that the front grasswort of front plate spring and front frame are lower than the two-stage stepping floor level.
Summary of the invention
The purpose of this utility model provides a kind of automobile front suspension front plate spring supporting structure that is specially adapted to the low floor operator's compartment for existing weak point in the above-mentioned prior art just, this structure can make three grades to mark time and become secondary and mark time as a kind of front suspension front plate spring of urban sanitation special purpose vehicle design supporting structure, satisfies the requirement of operator's compartment low floor.
The purpose of this utility model can realize by following technique measures:
The automobile front suspension front plate spring supporting structure that is applicable to the low floor operator's compartment of the present utility model comprises by the low early and high after vehicle frame that the step-by-step construction front/rear frame forms that is, and is installed in front plate spring front frame, rear support bracket for front plate spring and front plate spring assembly on the vehicle frame; Described front vehicle frame is positioned at under-cab, it is characterized in that: described front plate spring front frame is installed on the front section bicycle frame longeron outside of belly that is positioned at under-cab in affixed mode, and is arranged on the top of front plate spring front frame for the plate spring pin roll that connects the front plate spring assembly; Described rear support bracket for front plate spring is installed on the back segment chassis side rail bottom surface in affixed mode; One end of described front plate spring assembly by the leaf spring pin combine with the front plate spring front frame, the other end combines with rear support bracket for front plate spring by hanger, below a slice of described front plate spring assembly links to each other with bumper on being installed in the back segment chassis side rail by the bumper pin with the leaf spring of bumper mounting hole.
The beneficial effects of the utility model are as follows:
Because the utility model is installed in the front plate spring front frame on the front section bicycle frame longeron outside of belly that is positioned at under-cab in affixed mode, and the plate spring pin roll that is used for connection front plate spring assembly is arranged on the top structure mode of front plate spring front frame, this also just so that the front grasswort of front plate spring assembly and front plate spring front frame can be reduced under the cab floor plane, satisfied the suspension safe reliability of operator's compartment low floor structure vehicle, and the requirement of ride comfort and road-holding property, thereby realize the technical requirements of urban sanitation special vehicle operator's compartment low floor, also reduced the center of gravity of front suspension simultaneously.
