Definitions

• the present invention relates to robotized gearboxes, in which the engagement of the ratios (selection and passage) is done by means of two independent electric motors, fixed at their end by screws on the casing of mechanisms of the box. .
• It relates to a support system of an electric motor attached to the outside of a housing, consisting of a part of force recovery of the engine on the housing, away from its fastening means.
• the invention also relates to a novel method of assembling an electric drive motor outside a robotized gearbox.
• a robotized gearbox comprising an electric motor for selecting the speed lines, and an electric shifting motor on a selected line, these motors being fixed on the outside of the gearbox. mechanism casing.
• DE 197 21 449 discloses an electric motor fixing system on a rigid support, consisting of a side stand extending along the engine from the rigid support, and fixed to the engine by a strip of voltage surrounding the free end of the latter. Such a fastening system does not take advantage of the nature and geometry of the housing of the gearbox.
• a first solution is to force fit a holding piece on an outer raw rib of the housing.
• the tolerance intervals lead to maximum tightening, which generate too much stress on the holding part, as well as on the electric motor.
• the assembly is not easy, if one must simultaneously press the retaining piece on the electric motor and on the rib of the housing.
• the present invention aims to ensure effective maintenance of the engine on the housing, and to make it easier to assemble.
• the force recovery part is attached to one end of the motor, opposite to its fixing means.
• the force recovery part is force-fitted on the body of the electric motor, before being aimed at the housing.
• FIG. 1 illustrates a first solution
• FIG. 1 shows a casing 1 of gearboxes, on which are fixed an electric motor for selection of speed lines 2, and an electric gearshift motor 3, by fixing screws 2a and 3a.
• Each motor 2, 3 is also maintained by a support 4 at the end of the engine.
• the supports 4 are force-fitted on the engine 2, 3, and on an outer rib of the housing 1a, 1b.
• the assembly is not easy, especially if it must force force simultaneously the support on the electric motor and on the rib of the housing.
• this method of attachment is not reliable in all cases, given the manufacturing tolerances of the electric motor, the housing, and the support.
• the invention consists in fixing a force-recovery part on the casing, via a screw connection.
• a boss is made with drilling and tapping, on the housing of the gearbox.
• a passage hole is formed in the holding part, to let the screw.
• the force recovery part is made of plastic, a metal insert can be integrated to it, in order to take the clamping tension of the screw.
• the diameter of the through hole is defined to absorb the manufacturing tolerances of the different elements. Attachment of the force recovery part on the housing does not impose constraints in the holding part or in the electric motor. The maintenance without play is ensured by adherence at the screwed assembly, and by the shrinking of the force recovery part on the body of the electric motor.
• Figure 2 illustrates a non-limiting embodiment of the invention. It includes the selection and passage electric motors 2, 3 of Figure 1, their rear fixing screws 2a, 3a, on the housing 1, and the electric motor support systems 2, 3, fixed to the outside of the casing 1. They are composed of a force recovery part 4 of the engine on the housing away from its fastening means 2a, 3a. In the example described, the force recovery part 4 is attached to one end of the motor, opposite its fixing screws 2a, 3a. The force recovery parts 4 are force-fitted on the electric motor 2, 3, and screwed by their own fastening screws 6, on the casing 1.
• the fastening screws 6 are screwed into drilled screwings, and threaded on the casing 1, the force-taking part 4 has a through-hole for each fastening screw 6,
• the diameter of the clamping hole is defined so as to absorb the manufacturing tolerances of the elements of the assembly.
• the assembly of the force recovery part is easier than with known systems, and simpler, because it is possible to force force the holding part on the motor body electric, without having to simultaneously manage its fixing on the housing.
• the screwing operation of the workpiece on the housing can be performed in a second step, because it can be force-fitted on the body of the electric motor 2, 3, before screwing it on the housing 1.
• Any robotic gearbox comprising at least one electric motor for actuating its internal gearing mechanism fixed to the outside of its mechanism casing can benefit from the invention.
• the electric motors on the housing are additionally maintained by a support system according to the invention.
• the proposed measures can in particular be applied to a robotized gearbox where the two actuating motors, respectively an electric motor for selection of the gear lines, and an electric shifting motor on a selected line, both fixed to the gearbox. outside the mechanism housing.
