Description
Technical field
The present invention relates to a kind of heavy articulated truck front suspension technical field, the springing that a kind of specifically heavy articulated truck front suspension is used.
Background technology
At present, the elastic mechanism used of domestic heavy-duty tipper front overhang jib adopts rubber spring and hydro-pneumatic spring more.Such vehicle is empty, the at full load axle load changes characteristics greatly though their nonlinear characteristic is fit to, and all there are some shortcoming and defect in the two, for the rubber spring suspension; Because suspension guide mechanism rotates around different centers respectively, rubber spring also respectively around different center rotations, movement interference in various degree will inevitably occur when the wheel bob; Especially unreasonable, the installation error of guiding mechanism design reaches greatly when using wearing and tearing severe, and interfering can be more serious, so often causes the deformation fracture of rubber spring; Shortened its service life greatly; Thereby the rubber spring that needs in the use of actual vehicle constantly more to renew has increased use cost, and for hydro-pneumatic spring, manufacture difficulty is big, productive costs is high; And need special maintenance equipment; Maintenance trouble exists simultaneously that the skew because of the oil cylinder axis causes hydraulic oil leakage, defectives such as the easy scratch of oil cylinder inner surface with poor sealing in the working process.
Summary of the invention
The technical matters that the present invention will solve provides the springing that a kind of heavy articulated truck front suspension is used; It has outstanding elastic performance and damping performance; Can adapt to because of vehicle weight and change the demand that the damping frequency cause also need change; Guarantee the stability in the vehicle operating, also have advantage simple in structure, easily manufactured, that productive costs is low, it is little to take up room and use and maintenance expense is few.
The present invention is that the technical scheme that the deficiency that solves the problems of the technologies described above adopts is: the springing that a kind of heavy articulated truck front suspension is used; Be arranged between vehicle frame and the vehicle bridge; Mainly form by double-helix spring assembly and damper mechanism; The double-helix spring assembly is provided with two groups; And be separately positioned on the both sides of vehicle bridge, and described double-helix spring assembly mainly is made up of external spiral spring, inside spin spring, bearing inner sleeve and bearing outer sleeve, and the rotation direction of external spiral spring and inside spin spring is opposite; The also outside and inside spin spring that the external spiral spring housing is located at the inside spin spring is arranged between bearing inner sleeve and the bearing outer sleeve together, and the bearing inner sleeve and the bearing outer sleeve at double-helix spring two ends are connected on vehicle frame and the vehicle bridge.
The spring filament diameter of said external spiral spring is greater than the spring filament diameter of inside spin spring.
Described inside spin spring housing is located on the outer circumference surface of bearing inner sleeve, on the bearing inner sleeve, is provided with the limiting stopper assembly.
Described damper mechanism is made up of two bumper II of two the bumper I that are arranged on vehicle bridge one end and the vehicle bridge other end; Two bumper I are separately positioned on the both sides of vehicle bridge; The upper end of bumper I is connected with vehicle frame, and the lower end of bumper I is connected on the vehicle bridge through support; Two bumper II are separately positioned on the both sides of vehicle bridge, and the upper end of bumper II is connected with vehicle frame, the lower end of bumper II and be arranged on vehicle frame and be connected with link span between the vehicle bridge.
Described bumper I and bumper II are the cylinder type hydraulic bumper, are respectively equipped with rubber bush at the two ends of bumper I and bumper II.
The invention has the beneficial effects as follows:
1, the present invention provides the springing that a kind of heavy articulated truck front suspension is used; It has outstanding elastic performance and damping performance; Guarantee the stability in the vehicle operating; Also have advantage simple in structure, easily manufactured, that productive costs is low and use and maintenance cost is few, be fit to be applied to the elastic mechanism of engineering truck front suspension.
2, through the double-helix spring assembly is set between vehicle frame and vehicle bridge; This double-helix spring assembly is by being made up of external spiral spring, inside spin spring, the bearing outer sleeve that is arranged on vehicle frame upper bracket inner sleeve and is arranged on vehicle bridge; The rotation direction of external spiral spring and inside spin spring is opposite; The external spiral spring housing is located at the outer circumference surface of inside spin spring and is arranged on together between bearing inner sleeve and the bearing outer sleeve, so this elastic construction can not produce movement interference with guiding mechanism when the wheel bob, makes this double-helix spring assembly improve greatly service life; Greatly reduce maintenance cost; Also be provided with the limiting stopper assembly in this double-helix spring assembly, the maximum deformation quantity of restriction double-helix spring, the stability of assurance vehicle frame on the go.
3, this springing adopts the opposite double-helix spring assembly of rotation direction, and the outer spring rotation direction mainly is to consider on the contrary in adopting: inner little spring spring filament diameter is much thinner than outside big spring diameter.Be provided with if adopt in the same way, then externally in the big spring extension process, big spring pitch space can be bigger, and this void size can be greater than the spring filament diameter of inner little spring.Like this; If inner little spring rotation direction is identical with outside big spring; Then little spring is easy to sandwich in the space of outside big spring that (spring generation side direction, cross motion and deformation reason mainly are that spring is equipped with the gap on the one hand, even spring is installed very close to each otherly on the other hand, not only bear vertical power in the automotive suspension spring working process; Also bear owing to drives, brake, turn to interior stressed of horizontal surface such as centnifugal force); Even part sandwiches the possibility that also existence increases interior outer spring friction, thereby influences cushioning performance even structural safety, therefore interior outer spring rotation direction then can avoid this phenomenon to take place on the contrary easily.Simultaneously about two springs have different rotation directions and can offset a part of twist moment.
4, this springing is provided with bumper through the front-end and back-end in vehicle bridge; And the both sides at the vehicle bridge axis are distributed with bumper; All shock absorber upper ends all link to each other with vehicle frame, and the bumper lower end of vehicle bridge front end is connected on the vehicle bridge through support, and the bumper lower end of vehicle bridge rear end is connected on the link span; Through the position of reasonable Arrangement bumper, make this suspension possess good damping performance.
