Description
Technical field
The utility model relates to a kind of vehicle propons, specifically is a kind of super-tonnage electric tramsmission dumping car front axle assy.
Background technology
Along with the growth of domestic and international mining output, the large-tonnage automobile still can't satisfy the demand of mine transportation, and quarry tipper develops towards the super-tonnage direction, and the user is also increasingly high to the requirement of the performance of dumping car and quality simultaneously.Front axle assy as one of dumping car critical component; Bear vertical, horizontal, vertical load that vehicle receives; Realize functions such as Vehicular turn, braking, damping, because tonnage increases, load increases; Stressed also complicated more, existing tonnage dumping car propons can not satisfy the operating needs of super-tonnage dumping car.
Summary of the invention
The purpose of the utility model is to provide a kind of super-tonnage electric tramsmission dumping car front axle assy, with realize that this propons can bear that 300 tons of load-carryings and above tonnage vehicle receive vertically, laterally, vertical load, realize functions such as Vehicular turn, braking, damping.
The technical scheme of the utility model is: comprise front wheel spindle, front wheel hub, hydro-pneumatic spring suspension, power cylinder, tierod, wet plate disc brake; It is characterized in that; Front wheel spindle by about two form and constitute the front axle assy main body framework, two hydro-pneumatic spring strut mounts were connected with the vehicle frame left-right longeron about an end of left and right sides front wheel spindle passed through; The other end of left and right sides front wheel spindle is connected with front wheel hub through inside and outside two tapered roller bearings; Left and right sides hydro-pneumatic spring suspension is fixed through pressing plate and bolt and front wheel spindle; About two power cylinders be installed in respectively on the knuckle arm of the left and right sides; About two knuckle arms link together through tierod and be connected with left and right sides front wheel spindle respectively; Outer frame is installed on front wheel hub and the front wheel spindle through bolt respectively in the said wet plate disc brake, and the taper hole axis on the front wheel spindle becomes 91.5 ° of angles with wheel axis, makes the front vehicle wheel that is installed on the front wheel spindle form 1.5 ° camber angle.Be convenient to vehicle wheel under heavy duty and become vertical relatively with ground.
Said hydro-pneumatic spring suspension is a hydro-pneumatic spring suspension of taking back bullet control.
Said wet plate disc brake is isolated from the outside out through two floating seals plate disc brake inner chamber that will wet.
Two tapered roller bearing dos-s of said connection front wheel hub and left and right sides front wheel spindle are installed.
The utility model can promote two fronts wheel spindle and wheel around the rotation of hydro-pneumatic spring suspension axis, makes the rotation of wheel generation certain angle, and vehicle can realize turning to function.Can control the range difference (toe-in) of two wheel rear and front ends through the length of regulating tierod, make vehicle obtain linear driving performance preferably.Employing is taken back the hydro-pneumatic spring of bullet control as suspension, has compact conformation, and load-carrying capacity is big, advantages such as variable rigidity.Through regulating oil-gas ratin, can obtain different stiffness curves, and the stiffness variation scope is big, can effectively weaken the impact that the road surface is transmitted, avoid taking place resonance effect.Applicable to the ultra-large type electric power wheel self-discharging vehicle, can bear vertical, horizontal, vertical load that vehicle receives, realize the function of Vehicular turn, braking, damping, can adapt to road surface condition variation automatically, and weaken the impact load that bring on ups and downs road surface.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Embodiment:
The front wheel spindle of present embodiment by about two fronts wheel spindle 15 and 13 form, their constitute front axle assy main body framework, two hydro-pneumatic spring strut mounts 3,9 were connected with the vehicle frame left-right longeron about an end of left and right sides front wheel spindle 15,13 passed through respectively.The other end of left and right sides front wheel spindle is connected with front wheel hub with 18 through inside and outside two tapered roller bearings 17; Left and right sides hydro- pneumatic spring suspension 2,10 is for taking back the hydro-pneumatic spring type frame of bullet control; Its bar tube lower end is a cone, is enclosed within respectively on the front wheel spindle 15,13 in the taper hole, fixes through Bolt Connection and front wheel spindle 15,13 through pressing plate 16; The bar tube works to turn to stub simultaneously, bears lateral pressure.
