Definitions

  • the present invention relates to a drive arrangement and a vehicle comprising the drive arrangement.
  • Drive arrangements with drive units held between two walls, for example a housing, are known.
  • the drive unit is screwed to the two opposite walls.
  • a gap between the drive unit and one of the walls usually has to be bridged.
  • a retaining plate can be provided on the drive unit, for example, which is elastically deformed to bridge the gap.
  • this can have an unfavorable effect on the mechanical load and the tightness of the drive arrangement.
  • the drive arrangement according to the invention with the features of claim 1 is characterized in that a mounting of a drive unit that is advantageous in terms of load technology within a housing is made possible in a simple manner.
  • a drive arrangement comprising a drive unit and a housing, the drive unit being arranged between a first wall and a second wall of the housing.
  • the drive assembly includes a first mount and a second mount.
  • the first mount holds the drive unit on the first wall of the housing and the second mount holds the drive unit on the second wall of the housing.
  • the first mount has a tolerance compensation element which is screwed into the drive unit.
  • the tolerance compensation element is screwed into the drive unit in such a way that the tolerance compensation element bears against an inside of the first wall. As a result, a gap between the drive unit and the first wall is bridged by the tolerance compensation element.
  • the tolerance compensation element is preferably partially screwed into the drive unit, in particular not against a stop. This means that when the tolerance compensation element is screwed into the drive unit until it stops, there is a certain gap between an end face of the tolerance compensation element and the inside of the first wall. By partially unscrewing the tolerance compensation element starting from this screwed-in state, this gap can be bridged until the end face of the tolerance compensation element is in contact with the first wall.
  • the drive arrangement thus allows the drive unit and the housing to be assembled, which is advantageous in terms of mechanical loads.
  • a play-free arrangement of the drive unit between the two walls can be ensured without, for example, when the drive unit is screwed to the two walls on both sides, a bending load and/or a tensile load occurs in one of the components involved.
  • particularly lightweight materials can be used for the components of the drive arrangement.
  • the drive unit preferably rests against the second wall, with the second mount having a screw connection.
  • the drive unit is firmly connected to the second wall by means of the screw connection of the second bracket.
  • the drive unit is preferably first screwed to the second wall by means of the screw connection, with the gap to the first wall then being bridged by means of the tolerance compensation element.
  • the tolerance compensation element is particularly preferably screwed into the drive unit in such a way that the tolerance compensation element is subjected to pressure.
  • the drive unit is preferably clamped between the two walls of the housing and is thus subjected to pressure. With such a pressure load, a particularly favorable mechanical load on the drive unit can be made possible in order to ensure a long service life, in particular with a very lightweight construction of the drive arrangement.
  • the drive unit preferably has a holding element with a cylindrical opening.
  • the tolerance compensation element is screwed into the cylindrical opening of the holding element.
  • the holding element can preferably be made of sheet metal.
  • the cylindrical opening is preferably a through opening through the holding element.
  • the cylindrical opening is particularly preferably designed in the form of a sheet metal drawing, which is produced, for example, by deep-drawing. As a result, a particularly simple and cost-effective design of the drive unit and the first mount can be made possible.
  • the first wall has a housing opening which is arranged coaxially to the cylindrical opening of the holding element.
  • the housing opening is in particular a through-opening which completely penetrates the first wall.
  • the housing opening can be used, for example, to enable the tolerance compensation element to be actuated, for example by inserting a tool through the housing opening.
  • a holding device such as a screw, can preferably be arranged in the housing opening, by means of which the drive unit is held directly or via the tolerance compensation element.
  • the tolerance compensation element preferably has an actuating element which is set up to actuate the tolerance compensation element enabled by a tool.
  • the actuating element is preferably a multiplicity of recesses, which is formed in particular in the end face of the tolerance compensation element which faces the first wall.
  • the actuating element can be a hexagonal recess or a similar element which can be actuated by means of a tool. If the first wall has a housing opening, the tool can preferably be guided through this housing opening in order to actuate the tolerance compensation element via the actuating element.
  • the tolerance compensation element preferably has a self-tapping external thread.
  • a particularly simple and cost-effective drive arrangement can be provided, since the tolerance compensation element can simply be screwed directly into the drive unit, in particular without it being necessary to previously produce an internal thread in or on the drive unit.
  • a particularly simple and cost-effective design is possible if the drive unit has a sheet-metal holding element with a cylindrical opening into which the self-tapping external thread of the tolerance compensation element can be screwed.
  • the tolerance compensation element is particularly preferably a hollow screw which has an external thread and an internal thread.
  • the tolerance compensation element is preferably screwed into the drive unit by means of the external thread.
  • the tolerance compensation element can be fixed and thus, for example, the drive unit can be fixed to the first wall.
  • the first holder preferably has a fixing screw which protrudes through the first wall and which is screwed into the internal thread of the tolerance compensation element.
  • the fixing screw can be used to enable the drive unit to be attached to the first wall in a particularly stable manner, in particular in such a way that relative movements can be avoided.
  • the external thread and the internal thread of the tolerance compensation element preferably have different pitch directions. This means, the tolerance compensation element is screwed into the drive unit and the fixing screw is screwed into the tolerance compensation element with opposite directions of rotation. As a result, a counter effect can be achieved between the tolerance compensation element and the fixing screw, which serves as a securing mechanism for the two screws and provides a reliable and firm first mount.
  • the external thread is a left-hand thread and the internal thread is a right-hand thread.
  • the drive unit preferably has a motor and/or a gear. Due to the special arrangement and mounting within the housing, an optimal, reliable connection with an advantageous distribution of mechanical forces can be provided in order to enable a long service life for the drive unit. In addition, a low weight of the drive arrangement can be made possible in a simple and cost-effective manner.
  • the invention leads to a vehicle, preferably a vehicle that can be operated with muscle power and/or engine power, preferably an electric bicycle, which includes the drive arrangement described.
  • the housing can, for example, be part of a vehicle frame of the vehicle, it being provided in particular that the drive arrangement is attached in the exiting area of the seat tube and/or down tube.
  • the housing can be part of the bicycle frame and can be connected to the seat tube and/or down tube both mechanically and functionally as a stabilizing element.
  • FIG. 1 shows a sectional view of a drive arrangement according to a preferred embodiment of the invention
  • FIG. 1 shows a detail of the drive assembly Figure 1
  • FIG. 3 shows a detail analogous to FIG. 2, with a tolerance compensation element of the drive arrangement being actuated

  • FIG. 3 shows a detail of the drive arrangement 1, showing a step in further assembly.
  • FIG. 4 shows a detail of the drive arrangement 1 according to the preferred exemplary embodiment in the fully assembled state.
  • the drive arrangement 1 comprises a drive unit 2 (shown schematically) with a motor and a transmission.
  • the drive unit 2 is accommodated within a U-shaped housing 3, for example a frame member, which is connected to the seat and/or down tube.
  • An optional connection of the housing or frame element for accommodating the drive arrangement allows a pedal axle provided in the drive arrangement to be arranged accordingly in the outlet of the saddle tube and/or down tube.
  • the housing or frame element also serves to stabilize the seat tube and down tube attached to or terminating in it.
  • the housing 3 has a first wall 31 and a second wall 32 between which the drive unit 2 is arranged.
  • the drive arrangement 1 can be used, for example, in a vehicle that can be operated with muscle power and/or motor power, preferably an electric bicycle.
  • the drive arrangement 1 has a first mount 41, by means of which the drive unit 2 is fastened to the first wall 31, and a second mount 42, by means of which the drive unit 2 is fastened to the second wall 32.
  • the second mount 42 has a screw connection, by means of which a holding plate 23 of the drive unit 2 is screwed directly to the second wall 42 .
  • the retaining plate 23 is in direct contact with an inner side 32a of the second wall 32 .
  • the drive unit 2 has a sheet metal holding element 25 on the side facing the first wall 31 .
  • the sheet-metal holding element 25 has a cylindrical opening 26 which is designed in particular as a sheet metal passage.
  • a housing opening 31 b is formed in the first wall 31 coaxially with the cylindrical opening 26 of the holding element 25 .
  • the housing opening 31b is formed in two stages and has a shoulder 31c.
  • a first diameter 31d of the through-opening 31b is smaller than a second diameter 31e of the through-opening 31b in a region adjoining the inner side 31a.
  • screws of the first bracket 41 can be placed to enable the drive unit 2 to be fixed to the first wall 31, as described below.
  • the first bracket 41 has a tolerance compensation element 4 which is designed as a hollow screw and is screwed into the cylindrical opening 26 of the sheet-like holding element 25 .
  • the tolerance compensation element 4 has a self-tapping external thread 46 .
  • an internal thread in the cylindrical opening 26 of the sheet-metal holding element 25 can be dispensed with, as a result of which a particularly simple and cost-effective construction of the drive arrangement 1 can be made possible.
  • the external thread 46 is a left-hand thread.
  • the external thread 46 can also be a metric thread, with the retaining element 25 having a metric internal thread in the cylindrical opening 26 .
  • a metric press-in nut can be integrated in the holding element 25, into which the tolerance compensation element 4 is screwed.
  • the tolerance compensation element 4 also has a screw head 40 on its end face 4a facing the first wall 31, which rests against an outer side 25a of the retaining element 25 when the tolerance compensation element 4 is screwed completely into the retaining element 25 (see FIG. 2).
