Abstract
The utility model discloses a front axle of an electric wheel dump truck. The front axle comprises a frame, a steering assembly, a front wheel assembly, a suspension cylinder, a suspension transverse draw bar and a suspension diagonal draw bar, wherein one end of the suspension cylinder is connected with the frame by using a joint bearing, and the other end of the suspension cylinder is connected with the front wheel assembly; one ends of the suspension transverse draw bar and the suspension diagonal draw bar are connected with the suspension cylinder by using joint bearings, and the other ends of the suspension transverse draw bar and the suspension diagonal draw bar are connected with the frame by using joint bearings; and the suspension transverse draw bar, the suspension diagonal draw bar and the suspension cylinder are not on the same plane. The rigidity performance and the cushioning capacity of the vehicle can be improved, so that the smoothness for running of the vehicle is improved.
Description
Technical field
The utility model relates to a kind of vehicle part, especially a kind of dumping car propons.
Background technology
Dumping car is mining trolley, belong to one of mining equipment, be mainly used in the transportation of ore and other bulk cargo in mine, along with the continuous expansion of quarry tipper application demand and the maturation of technology thereof, dumping car develops towards large-tonnage, due to the growing interest of people to environment and energy problem, adopt the mining dump truck with electric wheels of electric transmission form to begin to be widely used simultaneously.Propons is as an important component part of electric power wheel self-discharging vehicle, bear longitudinal force that vehicle is subject to, transverse force, vertical load etc., realize Vehicular turn, braking and relax the functions such as impact, damped vibration, propons is connected with vehicle frame by suspension, the two ends installing wheel.At present, the dumping car propons is all that " candle " formula hangs and " A " type frame front-axle structure, although satisfied the requirement of strength and stiffness, but the continuous increase along with the dumping car tonnage, the rigid nature of vehicle highlights, and cushioning ability descends, thereby causes the ride comfort of Vehicle Driving Cycle poor.
Summary of the invention
For addressing the above problem, the utility model provides a kind of rigid nature, cushioning ability that can improve vehicle, thereby improves the ride comfort of Vehicle Driving Cycle.
The utility model provides a kind of electric power wheel self-discharging vehicle propons, comprise vehicle frame, turn to assembly, front wheel assembly, suspension cylinder, described suspension cylinder one end is connected with vehicle frame by oscillating bearing, the described suspension cylinder other end is connected with described front wheel assembly, also comprise and hang intermediate rod and hanging diagonal draw bar, described suspension intermediate rod is connected an end and is connected with described suspension cylinder by oscillating bearing respectively with hanging diagonal draw bar, described suspension intermediate rod is connected the other end and is connected with described vehicle frame by oscillating bearing respectively with hanging diagonal draw bar.
Described suspension intermediate rod, hanging diagonal draw bar respectively with suspension cylinder by being connected with oscillating bearing, described suspension cylinder, hang intermediate rod, hanging diagonal draw bar respectively with vehicle frame by being connected with oscillating bearing.The employing oscillating bearing connects, front wheel assembly can be realized the swing of top to bottom, left and right, front and rear, actv. weakens vibrations and impact load, improve the ride comfort of Vehicle Driving Cycle, again because wheel assembly correspondence before each has the suspension cylinder of self, hangs intermediate rod and hanging diagonal draw bar, therefore when jolting, a front wheel assembly can not affect the front wheel assembly of another one, improve the ride comfort of Vehicle Driving Cycle, also had compact conformation, rigidity of support is good, load-carrying capacity is strong, good damping effect, characteristics that cost is low.
As further improvement of the utility model: between described suspension cylinder and front wheel assembly, the junction is cone match.If adopt general fitting surface, when suspension cylinder and front wheel assembly occured, wearing and tearing appearred in fitting surface, and between described suspension cylinder and front wheel assembly, the gap will appear in the junction, and adopts cone match, even the wearing and tearing fitting surface also can closely cooperate.
as further improvement of the utility model: described vehicle frame both sides are respectively equipped with a described front wheel assembly, the described assembly that turns to comprises pitman arm, the left steering oil cylinder, the right steering oil cylinder, left steering pull bar and right steering pull bar, the left steering oil cylinder is connected with the left steering pull bar with the front wheel assembly on the left side and is connected, the right steering oil cylinder is connected with the right steering pull bar with the front wheel assembly on the right and is connected, the left steering pull bar is connected the other end and is connected respectively at an end of pitman arm with the right steering pull bar, pitman arm, the left steering oil cylinder is connected the other end and is connected with vehicle frame respectively with the right steering oil cylinder.To the adjustment of front wheel assembly can complete by adjusting left steering intermediate rod and right steering pull bar, easy to adjust, adopt symmetrical four-bar linkage, Installation and Debugging are simple.
