Definitions
- the invention relates to a transmission drive unit according to the preamble of claim 1.
- Such a transmission drive unit is known from DE 10 2005 012 938 A1.
- designed as a window lift drive gear drive unit designed as a gear element spur gear is mounted on a drive shaft, which in turn is mounted in an axis.
- a trained as a wrap spring locking element is provided which is mounted within a fixedly arranged hollow shaft.
- the invention has therefore set itself the task of developing a transmission drive unit according to the preamble of claim 1 such that a simpler and thus more cost-effective manufacturability is made possible.
- This object is achieved in a transmission drive unit with the features of claim 1.
- the invention is based on the idea to provide a single component for the storage of the transmission element and the locking element, which in addition to its function of the storage of the locking element takes over the radial bearing of the transmission element. Thereby It is necessary to produce only a single component in the required accuracy.
- the rotationally fixed element arranged a metal or plastic brake drum and the transmission element is a plastic existing spur gear.
- the gear drive unit is in particular when the brake drum is substantially sleeve-shaped or pot-shaped and acts with its outer wall as a bearing for the spur gear and with its inner wall as a bearing for the locking element.
- ribs are formed to reduce the friction between the spur gear and the brake drum on the outer wall of the brake drum or on the cylindrical inner wall of the spur gear, which act as bearings for the spur gear.
- the ribs are arranged at equal angular distances from one another and extend in the longitudinal direction, to allow uniform loading of the bearing and uniform wear.
- the ribs are formed on the spur gear or integrally formed and the spur gear is formed as an injection molded part.
- the spur gear is formed as an injection molded part.
- Brake drum radially arranged mounting tabs, which in corresponding chende recesses of the transmission housing engage positively. This allows a secure and easy attachment of the brake drum in the transmission housing.
- the spur gear is mounted axially within the gear housing between a housing bottom and a housing cover designed as a separate component.
- the coupling element is rotatably mounted on a concentric with the brake drum bearing pin and engages parallel to the axis arranged drivers with radial play in recesses of the spur gear.
- the bearing pin can be particularly simple and inexpensive and produce exactly when it is integrally formed on the existing plastic transmission housing.
- Fig. 1 is an exploded view of a transmission drive unit according to the invention.
- FIG. 2 shows a longitudinal section through the assembled gear drive unit according to FIG. 1.
- a transmission drive unit 10 is shown for an adjustment drive in a motor vehicle, in particular for a window lift drive.
- the gear drive unit 10 comprises a gear element designed as an obliquely toothed output gear made of plastic, which in the following is referred to as end gear.
- rad 1 1 is called.
- the spur gear 1 1 is driven by an electric motor, not shown, as shown in DE 10 2005 012 938 A1.
- the electric motor has a drive shaft 12 with a likewise helical gear 13, which meshes with the external toothing of the spur gear 1 1.
- the spur gear 1 1 is in a plastic transmission housing 15 of the transmission
- the gearbox housing 15 comprises a pot-shaped base part 16 and a housing cover 17 which is arranged on the upper side of the base part 16.
- the housing cover 17 is ring-shaped and in particular connected to the base part 16
- a bearing pin 18 is integrally formed, one end 19 of which protrudes from the housing cover 17.
- an output member 20 is rotatably mounted on the bearing pin 18.
- the driven element 20 is secured axially on the bearing pin 18 by means of a shaft tensioning ring 21.
- the output member 20 has on the side facing away from the housing cover 17 a toothing 23, via which the drive torque of the electric motor is transferable to a mechanism or kinematics of a window lifter, not shown, whereby a window pane is adjusted as a movable part.
- the output member 20 has two parallel and spaced from the bearing pin 18 extending driver 25, 26, which protrude into the interior of the transmission housing 15.
- two recesses 28, 29 are formed in the disk-shaped upper side 27 of the spur gear 11 (FIG. 1).
- the spur gear 1 1 is axially positioned or mounted with its ring gear 31 in the transmission housing 15.
- the underside 32 of the toothed rim 31 rests on an annular bottom region 33 of the base part 16 of the gear housing 15.
- the top 36 of the ring gear 31 is in turn arranged in operative connection with the housing cover 17.
- a brake drum 34 made of metal or plastic is arranged in the gearbox housing 15.
- the substantially sleeve-shaped or cup-shaped brake drum 34 lies with its lower half of the spur gear 1 1 located part of its outer wall 35 on a cylindrical wall 37 of the base 16 at.
- the wall 37 in the base part 16 also has a plurality of recesses 38, in the fastening tabs 39 of the brake drum 34 engage positively.
- About trained on the underside of the base 16 through holes can be the mounting tabs 39 of
- a locking element designed as a wrap spring 42 which acts as a load torque lock.
- the wrap spring 42 has two ends 43, 44 which project radially inwards and cooperate with the drivers 25, 26 of the output element 20.
- the wrap spring 42 occupies almost the entire height of the wall 35 of the brake drum 34 and is arranged radially with only a small distance from the inside of the wall 35, so that the wall 35 serves on its inside as a storage for the wrap spring 42.
- the wall 35 of the brake drum 34 not only serves to receive or support the wrap spring 42 but also to radially support the spur gear 11.
- the wall 35 of the brake drum 34 not only serves to receive or support the wrap spring 42 but also to radially support the spur gear 11.
- the wall 35 of the brake drum 34 on the circumferential inner side 45 of the ring gear 31 of the spur gear 1 1, a plurality, at regular angular intervals to each other arranged bearing ribs 46 are formed.
- the bearing ribs 46 cooperate with the region of the wall 35 of the brake drum 34 situated above the bottom region 32 of the base body 16, in that the bearing ribs 46 rest on the outside of the wall 35 or are spaced therefrom with minimal play.
- the extending in the longitudinal direction of the bearing ribs 46 are preferably integrally formed on the inside 45, which is cost-effectively realized in a formed as an injection molded spur gear 1 1. In the areas where there are no bearing ribs 46, annular gaps 47 are formed between the spur gear 1 1 and the brake drum 34.
- bearing ribs 46 can be arranged on the brake drum 34 instead of the spur gear 11. Also, depending on the application, can be dispensed with the training of bearing ribs completely.
