Abstract

The invention relates to a vehicle wheel lifting mechanism, which comprises vehicle wheels, a vehicle body and a dynamic system. A shaft sleeve is arranged on the vehicle body and is supported by a shaft sleeve stand; an oscillating arm shaft is arranged in the shaft sleeve in a sleeving way; each of two ends of the oscillating arm shaft is respectively connected with an oscillating arm fixedly; the oscillating arms are respectively connected with transmission cases arranged at two sides of the vehicle body through fulcrum bars; one end of each fulcrum bar is hinged with the corresponding oscillating arm and the other end of each fulcrum bar is hinged with the corresponding case; the vehicle body is also provided with a support arm; a hinged hydraulic cylinder is arranged at the tail end of the support arm; a push rod end of the hydraulic cylinder is hinged with the corresponding transmission case at the same side; the transmission case is internally provided with a chain type transmission; one end of each chain type transmission is connected with a dynamic output shaft of the dynamic system and the other end of the each chain type transmission is connected with a wheel shaft of the corresponding vehicle wheel; the hydraulic cylinder is controlled to push and pull the transmission cases to lead the vehicle wheels at two sides to form height difference for adapting to roadbed, so as to keep the vehicle body to be in a horizontal state, so that the purpose of keeping a vehicle driving stably can be realized, vehicle rollover or other accidents can be prevented, and the operating environment of drivers also can be improved.

Description

The wheel lifting mechanism

Technical field

The present invention provides a kind of wheel lifting mechanism, especially is applied in the wheel lifting mechanism on trac. or the reaper.

Background technology

Existing trac. or reaper are when remote land on slope or hollow go on the ground; Car body meeting run-off the straight or wigwag motion; The as easy as rolling off a log like this vehicle rollover that makes perhaps causes other accident; The vehicle that acutely waves simultaneously also lets the driver feel under the weather, and the operation driving is easy to make driver fatigue under rugged environment like this, produces hidden danger.

Summary of the invention

The present invention provides a kind of wheel lifting mechanism, can make the trac. or the reaper that go at remote land on slope or hollow keep the car body balance on the ground with this mechanism, realizes the purpose of smooth-ride and safe operation.

Technical scheme of the present invention is: a kind of wheel lifting mechanism, comprise wheel, car body and power system, and it is characterized in that: described car body is provided with axle sleeve; Axle sleeve is supported by sleeve rack, is set with arm shaft in the axle sleeve, and the arm shaft two ends are fixed with swing arm respectively; Swing arm is connected with the transmission gearbox that is arranged on the car body both sides respectively through pole, and described pole one end and swing arm are hinged, and the other end and transmission gearbox are hinged; Also be provided with hold-down arm on the described car body; The hold-down arm end is equipped with the pivotally attached hydraulic actuating cylinder, and the cooresponding transmission gearbox of hydraulic actuating cylinder push rod end and homonymy is hinged, is provided with the chain-type driving device in the described transmission gearbox; Chain-type driving device one end is connected with the power system power take-off shaft, and the other end is connected with wheel hub.

Advantage of the present invention is that trac. or reaper are gone when remote land on slope or hollow ground; Use manually or the automatically controlled hydraulic actuating cylinder makes the wheel of both sides form diff-H to adapt to the road surface through the push-and-pull transmission gearbox; Let car body keep horizontality; Reach the purpose of smooth-ride, prevent vehicle rollover or cause other accident, also can greatly improve driver's operating environment simultaneously.

The specific embodiment

The wheel lifting mechanism comprises wheel 1, car body 9 and power system 10, and described car body is provided with axle sleeve 5; Axle sleeve is supported by sleeve rack 6 and is installed on the car body, in axle sleeve, is set with arm shaft 11, is fixed with swing arm 4 respectively at the arm shaft two ends; Swing arm is connected with the transmission gearbox that is arranged on the car body both sides 2 respectively through pole 3; Described pole one end and swing arm are hinged, and the other end is hinged with the support 14 that is arranged on the transmission gearbox, also is provided with hold-down arm 8 on the described car body; The hold-down arm end is equipped with pivotally attached hydraulic actuating cylinder 7, and the cooresponding transmission gearbox of hydraulic actuating cylinder push rod end and homonymy is hinged.

Be provided with the chain-type driving device in the described transmission gearbox; Be used for transmission of power with power system output to wheel, and this chain-type driving device is made up of two cover bearings, 16 pairs, two sprocket shafts 15, four sprocket wheels 12, two chains 13, and wherein two overlap bearing pairs and are installed in the corresponding position of transmission gearbox tank ends respectively; Sprocket shaft is housed respectively in the at both ends bearing pair; Two sprocket wheels are housed respectively on two sprocket shafts, and with the chain link, the sprocket shaft of chain-type driving device one end is connected with the power system power take-off shaft sprocket wheel at two ends with respectively; The sprocket shaft of the other end is connected with wheel hub, and the structure of double-stranded bar makes the more reliable of power transmission.

When vehicle ' at remote land on slope or hollow on the ground the time, manually or by the operation of horizontal controller automatic guidance operation hydraulic actuating cylinder, hydraulic actuating cylinder push rod end promotes the Left Drive case downwards descends left wheel; At this moment; This transmission gearbox is that the center of circle is rotated down and drop-down and its pivotally attached left branching rod with the power system output shaft, and left branching rod spurs left swing arm, and left swing arm drives arm shaft and in axle sleeve, rotates; Right swing arm upwards lifts because of arm shaft rotates and the right pole of its pivotally attached; It is that the center of circle rotates up right wheel is raise with the power system output shaft that right pole drives right transmission gearbox, and right wheel that raise this moment and the left wheel of decline formation diff-H have promptly been accomplished adjustment; The horizontality that has kept car body has guaranteed steadily going of safety of vehicle.
