Abstract
This heavy-duty tractor front suspension apparatus, comprise vehicle frame and be vertically fixed on the vehicle bridge below vehicle frame, also comprise and be vertically fixed on crossbeam I below vehicle frame front end, be vertically fixed on crossbeam II below vehicle frame rear end, be individually fixed in two plate spring front brackets at crossbeam about I two ends, be individually fixed in two leaf spring after poppets at crossbeam about II two ends, be fixed on two bumpers at two ends, vehicle frame left and right by bumper upper bracket and be fixed on two bumper lower brackets at two ends, vehicle bridge left and right.Because steel plate spring assembly is arranged in the below of vehicle bridge, therefore effectively reduce chassis frame height.By arranging crossbeam I and crossbeam II respectively at plate spring front bracket and leaf spring after poppet place, avoid below steel plate spring assembly layout and vehicle bridge, very easily cause plate spring front bracket and the long problem causing intensity low of leaf spring after poppet cantilever, greatly strengthen the reliability of plate spring front bracket and leaf spring after poppet.
Description
Technical field
The utility model relates to heavy motor vehicle technical field, is specifically related to a kind of heavy-duty tractor front suspension apparatus.
Background technology
Elastic element many employings steel spring in the suspension system of existing heavy motor vehicle, and steel spring is generally positioned at above vehicle bridge, for special traction car chassis frame height being had to a particular/special requirement, steel spring is positioned at above vehicle bridge and easily causes chassis frame height superelevation, cannot meet chassis frame height designing requirement.
Summary of the invention
The utility model, in order to overcome the deficiency of above technology, provides a kind of steel spring and is positioned at the heavy-duty tractor front suspension apparatus effectively reducing chassis frame height below vehicle bridge.
The utility model overcomes the technical scheme that its technical matters adopts:
This heavy-duty tractor front suspension apparatus, comprise vehicle frame and be vertically fixed on the vehicle bridge below vehicle frame, also comprise the crossbeam I be vertically fixed on below vehicle frame front end, be vertically fixed on the crossbeam II below vehicle frame rear end, be individually fixed in two plate spring front brackets at crossbeam about I two ends, be individually fixed in two leaf spring after poppets at crossbeam about II two ends, be fixed on two bumpers at two ends, vehicle frame left and right by bumper upper bracket and be fixed on two bumper lower brackets at two ends, vehicle bridge left and right, the hinged bumper lower end being installed on homonymy of described bumper lower bracket side, steel plate spring assembly one end is hinged is installed on plate spring front bracket lower end, its other end is by the hinged lower end being installed on leaf spring after poppet of plate spring lifting lug, panel spring hold-down plate is provided with below described steel plate spring assembly middle part, some saddle clamps are fixed on bumper lower bracket through screwing after panel spring hold-down plate and steel plate spring assembly successively.
In order to reduce weight, above-mentioned crossbeam I is tube-shaped structure.
Produce when beating to prevent transmission shaft and interfere, above-mentioned crossbeam II is provided with the groove caved in upward.
In order to protect bumper, above-mentioned vehicle frame left and right is fixed with suspension limiting stopper below two ends respectively, and when piston lever of reducer is retracted completely, bumper lower bracket contacts with suspension limiting stopper.
The beneficial effects of the utility model are: because steel plate spring assembly is arranged in the below of vehicle bridge, therefore effectively reduce chassis frame height.By arranging crossbeam I and crossbeam II respectively at plate spring front bracket and leaf spring after poppet place, avoid below steel plate spring assembly layout and vehicle bridge, very easily cause plate spring front bracket and the long problem causing intensity low of leaf spring after poppet cantilever, greatly strengthen the reliability of plate spring front bracket and leaf spring after poppet.

Detailed description of the invention
Be described further below in conjunction with accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 pairs of the utility model.
This heavy-duty tractor front suspension apparatus, comprise vehicle frame 1 and be vertically fixed on the vehicle bridge 13 below vehicle frame 1, also comprise the crossbeam I 12 be vertically fixed on below vehicle frame 1 front end, be vertically fixed on the crossbeam II 14 below vehicle frame 1 rear end, be individually fixed in two plate spring front brackets 2 at crossbeam about I 12 two ends, be individually fixed in two leaf spring after poppets 5 at crossbeam about II 14 two ends, be fixed on two bumpers 10 at vehicle frame about 1 two ends by bumper upper bracket 11 and be fixed on two bumper lower brackets 9 at vehicle bridge about 13 two ends, hinged bumper 10 lower end being installed on homonymy of bumper lower bracket 9 side, steel plate spring assembly 3 one end is hinged is installed on plate spring front bracket 2 lower end, its other end is by the hinged lower end being installed on leaf spring after poppet 5 of plate spring lifting lug 4, steel plate spring assembly 3 is provided with panel spring hold-down plate 6 below middle part, some saddle clamps 7 are fixed on bumper lower bracket 9 through screwing after panel spring hold-down plate 6 and steel plate spring assembly 3 successively.Because steel plate spring assembly 3 is arranged in the below of vehicle bridge 13, therefore effectively reduce chassis frame height.By arranging crossbeam I 12 and crossbeam II 14 respectively at plate spring front bracket 2 and leaf spring after poppet 5 place, avoid below steel plate spring assembly 3 layout and vehicle bridge 13, very easily cause plate spring front bracket 2 and the long problem causing intensity low of leaf spring after poppet 5 cantilever, greatly strengthen the reliability of plate spring front bracket 2 and leaf spring after poppet 5.
Crossbeam I 12 can be tube-shaped structure.The crossbeam I 12 of tube-shaped structure had both possessed excellent resistance to bending, had again lightweight feature, reduced productive costs.Crossbeam II 14 can be provided with the groove caved in upward.Because transmission shaft passes from the gap between crossbeam II 14 and vehicle bridge 13, therefore on crossbeam II 14, arrange groove makes it be shoulder pole shape, transmission shaft effectively can be prevented when radial runout and the crossbeam II 14 of upper end interferes, improve the reliability of use.
Suspension limiting stopper 8 can be fixed with respectively below vehicle frame about 1 two ends; when bumper 10 piston rod is retracted completely; bumper lower bracket 9 contacts with suspension limiting stopper 8, therefore can available protecting bumper 10, impacts the situation generation causing bumper 10 to damage when preventing transition from compressing.
