Abstract
The invention belongs to the field of balance shafts and relates to a balance shaft assembly having a support assembly composed of spliced and welded steel plates, in particular to a welded balance shaft assembly comprising the support assembly. The support assembly comprises a balance member having an arch trough. The lower portion of the balance member is provided with a support. A framed cavity forms between the balance member and the support. Two ends of the balance member are provided with balance shaft mounting blocks respectively. The balance shaft mounting blocks are provided with a left shaft hole and a right shaft hole respectively. A left half shaft and a right half shaft are disposed in the left shaft hole and the right shaft hole respectively. The left half shaft and the right half shaft form a balance shaft. The outside of each balance shaft mounting block is provided with a dust cover. The support assembly is made by welding 16Mn steel plates. When the support cracks, the assembly can be welded and maintained with no need for replacement; maintenance cost is saved. The balance shaft is in a split structure of left and right half shafts; the shaft which cracks or wears can be replaced independently; the cost of the half shafts is lower than that of the original integral shaft.
Description
Technical field
The invention belongs to balance shaft field, relate in particular that a kind of bracket assembly is welded by steel plate splicing and by the welded type balance shaft assembly of left half axle and right axle shaft Compositional balance axle.
Background technology
What dumping car adopted with balance shaft assembly support at present is Casting Parts, axle and support are connected with to beat to sell to fix and close fixing with rivet hot, when having crackle, support there is no actv. maintenance means, at support or axle, crack like this, wear and tear, must change during the fault such as fracture simultaneously the connector of axle and support, even if just one of them part has fault also must all change, make service expenditure high; The balance shaft assembly working environment that now dumping car is used is in addition all more severe, because oil sealing end face is to be directly exposed to airbornely, causes dust and muddy water to be easier to enter into oil sealing cutting edge, and oil sealing cutting edge is scratched and premature failure.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of dumping car balance shaft assembly of being convenient to maintenance.
For solving the problems of the technologies described above, the invention provides a kind of welded type balance shaft assembly, comprise bracket assembly, described bracket assembly comprises the balanced body with arcuate recess, described balanced body bottom is provided with support, described balanced body and support form the space of a frame type, described balanced body two ends are also respectively arranged with balance shaft mount pad, on described two balance shaft mount pads, be respectively arranged with left axis hole and right axis hole, in described left axis hole and right axis hole, be respectively arranged with left half axle and right axle shaft, described left half axle and right axle shaft Compositional balance axle, between described left half axle and right axle shaft and bracket assembly for removably connecting, on described balance shaft mount pad cylindrical, be provided with dust boot.
Preferably, the balanced body of described bracket assembly, support and balance shaft mount pad are welded by steel plate splicing, between described balanced body and support and balance shaft mount pad, are and are welded to connect, and the material of described steel plate is 16Mn steel.
Preferably, described balanced body and balance shaft mount pad top are all welded with support base plate.
Preferably, described left half axle and right axle shaft inner end are provided with respectively left pressing plate and right pressing plate, with bolts between described left pressing plate and right pressing plate and left half axle and right axle shaft.
Preferably, described left half axle and right axle shaft periphery are socketed with axle housing respectively, between the left half axle of described axle housing and balance shaft and right axle shaft, by bearing, are connected, and between described bearing and axle housing, are provided with oil sealing, and described oil sealing end is provided with dust boot.
Preferably, described dust boot one end is arranged on the cylindrical of semiaxis, and the other end is arranged on axle housing cylindrical.
Preferably, described left half axle and right axle shaft outer end are provided with end cap.
The principle of work of the welded type balance shaft assembly that technical solution of the present invention proposes is:
Balance shaft assembly is connected and fixed by the support base plate on bracket assembly, front-rear axle propelling rod, axle housing three parts and vehicle frame;
Axle housing is connected with right axle shaft with the left half axle of balance shaft by bearing, and axle housing can be taken exercises with respect to left half axle and the right axle shaft of balance shaft; Bearing makes the bearing enclose can locking by being added in the gear oil of axle housing, and oil sealing makes gear oil not reveal; End cap effect is also that gear oil is not revealed;
Vehicle frame transmits power by leaf spring to axle housing by the carrying force of vehicle body, because of the vibrations of leaf spring, left half axle and the right axle shaft with respect to balance shaft swings axle housing, if the bad axle housing of road conditions also can be made in the bob of leaf spring the vertical tremor on balance shaft, vehicle frame is delivered to the carrying force of vehicle body on support base plate by midship mounting simultaneously, make a part of load of balance shaft carrying vehicle frame, and it is also the same time, front-rear axle makes balance shaft and front-rear axle formation interlock integral body make front-rear axle load be evenly distributed by propelling rod application force on balance shaft simultaneously, thereby make balance shaft and front-rear axle form the suspended structure of organic integrated support vehicle body load.
Adopt the beneficial effect of technique scheme to be:
Bracket assembly integral structure all adopts 16Mn steel plate splicing to be welded, this structure effectively raises its bearing capacity compared to the balance shaft support of spheroidal graphite iron QT500-7 casting of the prior art, tensile strength is also increased to 630Mpa by original 500Mpa, and bracket assembly adopt structures shape that steel plate splicing is welded its be convenient to the feature of maintenance, when cracking fault, support can weld maintenance, do not need to change, save maintenance cost; The balanced body of while bracket assembly has increased the area of contact with crossbeam, and the power of support attachment face in unit area has been reduced, and has extended the service life of support;
Balance shaft adopts breakaway-element to consist of left and right half, when axle fracture or wearing and tearing, can change separately semiaxis, and the original integral shaft cost of half axial ratio is low;
The left half axle of bracket assembly and balance shaft and the connection mode of right axle shaft adopt pressing plate to be connected with bolt arrangement, easy to maintenance, Panasonic's bolt and the pressing plate fault semiaxis of can dismantling;
Dust boot one end is arranged on semiaxis cylindrical, and the other end is arranged on axle housing cylindrical, avoids oil sealing port directly to contact with air, reduces muddy water and greasy dirt and enters into oil sealing cutting edge, improves the service life of oil sealing.
