Definitions

  • the invention has its origin in the search for a solution to the problem of driving the compacting rollers of a compactor.
  • the compactor comprises a single compacting roller, which is rotatably mounted relative to the frame of the compactor with the interposition of flexible vibration isolation elements.
  • a hydraulic motor generally at low speed and with high torque, is coupled to the compacting roller and ensures its drive, being placed at one end of, and coaxial with said compacting roller.
  • an eccentric mass is placed inside, hollow, of the compaction roller, and is rotated by means of another motor, generally constituted by a high speed hydraulic motor and little couple.
  • This other motor is placed at the other end of the compaction roller, coaxial with it, and drives the eccentric mass via a shaft.
  • certain compactors comprise two coaxial compacting rollers, in the extension of one another, and coupled to two separate hydraulic motors.
  • the rollers can have different rotations, which avoids the destruction of compacted soils.
  • On the side where the drive motor for the eccentric mass is already placed it is not possible to directly couple the drive motor for the compaction roller corresponding to this compaction roller.
  • the known solution consists in offsetting said drive motor of the compacting roller; placing it where there is room, that is to say next to the eccentric mass drive motor; and coupling the drive shaft of the drive motor of the compaction roller to said compaction roller by means of a ring gear and pinions of gears. The whole is complex, bulky, heavy and expensive.
  • the object of the invention is to remedy these drawbacks by proposing a solution where the two motors located on the same side of one of the compacting rollers are arranged coaxially with one another and with this compacting roller. To do this, a new hydraulic motor had to be studied before it could be applied to compactors, a hydraulic motor fitted with a brake.
  • the invention therefore firstly relates to an assembly of a hydraulic motor and a brake which is coupled thereto, comprising: a central motor element traversed by a first axial recess; a peripheral motor element mounted for rotation relative to said central motor element about an axis; and a brake shaft, which is integral, with respect to said relative rotation, of said central motor element and which extends axially concomitantly opposite the central motor element and opposite the brake.
  • the brake comprises a casing, at least part of which is integral with the peripheral element of the engine, and which itself comprises a bottom arranged transversely to the axis; b) the bottom has a through bore; c) the brake shaft passes completely through the assembly of the motor and the brake, and said bore at the bottom of the brake housing; d) two seals are interposed between the brake shaft and, on the one hand, the first recess of the central element of the engine, on the other hand, said bore in the bottom of the brake housing, respectively; e) the brake shaft has a second recess passing entirely through it.
  • the invention also relates to a compactor which comprises at least one assembly according to one of the preceding definitions.
  • this compactor comprises at least one set of a hydraulic motor and a brake in accordance with the preceding definitions and further comprises: two separate compacting rollers, cylindrical, mounted for rotation about a common geometric axis; two main hydraulic motors for driving said rollers coupled between the compactor frame and, one of the main hydraulic motors, one of said compacting rollers, the other main hydraulic motor, the other compacting roller, a first of said main hydraulic motors forming part of an assembly according to one of the preceding definitions; an eccentric mass relative to said geometric axis; and a third motor for driving said eccentric mass, coupled between the frame of the compactor and said mass, and comprising two elements mounted for rotation relative to each other; however that, on the one hand, a first of said elements of the third motor is made integral with respect to the rotation of the peripheral element of the first main hydraulic motor, on the other hand, the second of the two said elements of the third motor is made integral with respect to the rotation of a shaft which passes through the second recess formed in the brake shaft of the brake
  • the main advantage of the invention lies in the fact that the axial recess in the brake shaft allows the passage of a drive shaft connecting the eccentric mass to its drive motor, while making it possible to place the hydraulic motor for driving the compacting roller coaxially with said compacting roller and thus directly drive this compacting roller.
  • the brake shaft 37 passes entirely through the engine, in particular its cylinder block 8 and its internal fluid distributor 21, and, the brake, including the cover 42 of its casing (32-42).
  • the axial recess 40 itself passing entirely through the brake shaft 37, it is possible to pass a connection, such as a motion transmission shaft, through the assembly of the motor and the brake, passing through the axial recess 40, as described in the application example shown in Figure 2.
  • FIG. 2 schematically represents the two cylindrical compacting rollers 59, 60 of a compactor.
  • the axial recess 40 which comprises the assembly of FIG. 1, allows the axial crossing of the motor and the brake by any element, such as the shaft 81 of FIG. 2, this element which may be other than a drive shaft and which may, for example, in certain different applications be constituted by pipes or measuring instruments.
  • the seals 44, 45, 46 ensure satisfactory operation of the assembly, while the adapter flange 53, which allows the adaptation of any third motor 76 driving the shaft 81, also acts as a starting support for the elastic washer 57.
  • assemblies in which the peripheral part 32 of the brake housing is in one piece with part 1B of the peripheral element of the motor housing, assemblies, of course provided with a removable cover 42 (removable fixing by the 'intermediate flange 53 and screws 54); and assemblies, in which the brake housing is in one piece (peripheral part 32 and cover 42 in one piece), fixed to part 1B of the motor housing by means of a removable fixing.
