Abstract

The solution is to use the same gearbox for driving the tread and pneumatic wheels of compaction rollers. The gearbox consists of a supporting part and a supporting part, which can be rotated relative to each other to a position so that the whole assumes a suitable shape for installation into the inner space of the tread or for driving pneumatic wheels.

Gearbox for driving compaction rollers

It is solved to use the same gearbox for propulsion and pneumatic wheels in compaction rollers. The transmission housing consists of a support part and an end piece which can be rotated relative to one another such that the assembly assumes a suitable shape for mounting in the interior of the tread or for driving pneumatic wheels.

BACKGROUND OF THE INVENTION The present invention relates to a gearbox for driving compaction rollers, the purpose of which is to arrange the various parts of the gearbox for different types of roll drives.

The transmission housings of the compaction rollers used so far are structurally different according to the types of compaction rollers. For example, in the case of tandem rollers equipped with two steel treads, it is necessary to place the gearbox for driving the treads in the interior of the treads so that it does not protrude from the machine frame contour. For cylinders with a two-wheel tractor and a pneumatic drive axle, the gearbox must be located outside the drive wheels. Another known gearbox is designed to accommodate three parallel shafts, two output shafts for driving a rake or a tire wheel and a brake, and one input shaft for a driving hydraulic motor. Both the input shaft and the output shaft for the brake are directed into the space inside the machine, thereby hampering the accessibility of the hydraulic motor and the brake during assembly, maintenance and repair. The big disadvantage is the production of a large number of different construction cases. As a rule, there is a small-series production of cabinets, which is inefficient, despite the need to maintain a wide range of spare parts.

These drawbacks are eliminated by the gearbox according to the invention, which consists in that the gearbox is made up of a support and an articulated part interconnected by a flange connection with a centering collar and regularly spaced connecting screws. On the outside of the support part opposite the output shaft, there is a flange with holes for the connecting bolts of the coupling piece, the brake output shaft facing the outer contour of the compaction roller frame.

The gearbox arrangement according to the invention allows the two housing parts to be aligned in such a position that they can be mounted either in the space inside the tread or on the tractor frame of the tire wheels. By producing a two-part housing, the production effort is reduced and the gearboxes can be used more rationally.

One embodiment of the gearbox according to the invention is shown in the drawings, in which Fig. 1 shows a side view of the drive of the compaction roller, and Fig. 2 shows a side view of the drive of the tire wheel of the compaction roller. Fig. 3 is a plan view of a gearbox for driving a tire wheel, one possible solution of the flange connection of a portion of the casing being shown in partial section.

The gearbox of the fir according to the invention consists of a housing support part 1, attached to the frame 2 by a fixed or removable foot 14,

The output shaft 3, driving the tread 4 (see Fig. 1) or the tire wheel 5 (see Fig. 2) and the output shaft of the brake 6, projecting from the outer part of the housing 2 towards the outer contour of the frame 2 on which the brake 7 is mounted. The housing support part 1 is connected by means of a flange connection 8 of the centering collar 9 and the regularly spaced connecting bolts 10 to the housing part 11 from which the input shaft 12 connected to the hydraulic motor 13 protrudes.

The housing support part 1 and the housing part 11 can be rotated relative to each other about the centering collar 9 to the position required by the space conditions when mounted in the compaction roller and by means of the connecting bolts 10 can be permanently secured in this position. A connecting flange 15 with holes for the connecting bolts 17 is formed on the outer housing part 11 of the housing in a position opposite the output shaft 3. By means of the connecting flange 15 and the connecting piece 16, the drive axle of the compaction roller can be formed from two gearboxes. .

The gearbox can be suitably used in various types of compaction rollers, and a pair of gearboxes can be used to assemble a drive axle with separate drive for each wheel.
