Abstract
The utility model relates to a rear suspension device of an underground vehicle, which belongs to the manufacturing field of engineering transportation equipment used in underground coalmine. The rear suspension device is characterized in that one end of a rear suspension cylinder is hinged with the front end of a rear frame, the other end is hinged with the upper end of a rear wheel arm, and the lower end of the rear wheel arm is hinged with the rear end of the rear frame; a wheel is installed on the central axle of the rear wheel arm; when the vehicle moves, the wheel vibrates up and down due to the impaction from the ground, so as to enable the rear wheel arm to generate a turn angel on the rear frame, the rotation of the rear wheel arm contracts the rear suspension cylinder; because oil and high pressure gas are provided in the rear suspension cylinder, the vibrational energy generated through vehicle driving is taken by the rear suspension cylinder when the rear suspension cylinder stretches; therefore, the purpose of damping is realized, and the service life of the vehicle is prolonged.
Description
One, technical field
The utility model relates to a kind of down-hole transport trolley rear linkage, belongs to underground mine use engineering transportation device and makes the field.
Two, background technology
Transport vehicle generally adopts rigidity or semi-rigid suspension gear under the existing well, the vibrational energy of the vehicle ' that can not in time decay is after vehicle uses a period of time, because tired vibration can cause the fatigue damage of vehicle upper spare, increase the maintenance cost of vehicle, shortened the vehicle operation life-span.
Three, summary of the invention
The purpose of this utility model is to provide a kind of vibrational energy of the vehicle ' that can in time decay, and improves the rideability of vehicle, has reduced the maintenance cost of vehicle, has prolonged the down-hole transport trolley rear linkage in vehicle operation life-span.
Technical solution: rear overhang cylinder one end of the present utility model is hinged with back vehicle frame front end, and the other end and rear wheel arms upper end are hinged, and the rear wheel arms lower end is hinged with vehicle frame rear end, back; Wheel is installed on the center shaft of rear wheel arms.
Back vehicle frame, rear overhang cylinder and rear wheel arms are formed a scalable triangular structure.
The utility model is owing to be provided with the rear overhang cylinder between back vehicle frame and rear wheel arms, and the three forms a scalable triangular structure, wheel is installed on the center shaft of rear wheel arms, so when vehicle ', wheel 5 is subjected to ground shock and produces up-down vibration, rear wheel arms is rotated to the back vehicle frame, the rotation compression rear overhang cylinder of rear wheel arms, because the rear overhang cylinder interior has dash pot valve, fluid and high pressure gas, along with stretching of rear overhang cylinder, the vibrational energy of vehicle ' is absorbed by the rear overhang cylinder, has reached the purpose of vibration damping, has prolonged the vehicle operation life-span.
Four, description of drawings
Fig. 1 is the utility model structural representation.
Five, the specific embodiment
The utility model suspension gear is made up of back vehicle frame 1, rear overhang cylinder 2, connecting pin 3, rear wheel arms 4, wheel 5.Rear overhang cylinder 2 one ends are connected on the hinge hole A of back vehicle frame 1, and the other end is connected on the hinge hole B of rear wheel arms 4 upper ends, and the hinge hole C of rear wheel arms 4 lower ends links to each other with vehicle frame 1 back stomidium; Back vehicle frame 1, rear overhang cylinder 2, rear wheel arms 4 are formed a scalable triangular structure.Wheel 5 is installed on rear wheel arms 4 center shafts, when vehicle ', wheel 5 is subjected to ground shock and produces up-down vibration, vehicle frame 1 rotates after making 4 pairs of rear wheel arms, and the rotation of rear wheel arms 4 makes rear overhang cylinder 2 carry out fore and aft motion, because there are dash pot valve, fluid and high pressure gas in rear overhang cylinder 2 inside, along with stretching of rear overhang cylinder 2, inner fluid is by dash pot valve, and the vibrational energy of vehicle ' is absorbed into thermal dissipation by rear overhang cylinder 2 and falls, and has finished vibration-damping function.
