Abstract
The invention relates to a water wiping device (10) that has an electric motor with a speed reducer. The output shaft (18) of the electric motor can be rotatably mounted in a dome (14) of a speed reducer housing (12) by bearings (20, 22), and a segment (38) extends out of the dome (14) of the speed reducer far, wherein the output shaft (18) is axially fixed by a starting surface (30) disposed opposite to the head face of the dome of the speed reducer by means of an element (26) axially fixedly connected with the segment (38) and is surrounded by a protective cover (26). The suggestions are as follows: the protective cover (26) provided with the starting surface (30) is made of steel plates and is mounted on the segment (38) without incisions extending from the dome (14) of the speed reducer by press fit, wherein the press fit is such selected that the minimum tractional force of the protective cover (26) on the output shaft (18) is larger than the maximum axial force acting on the output shaft (18) during operation.
Description
Technical field
The present invention relates to a kind of wiper device.
Background technology
At present in windshield wiper engine with a knock-down engine crank, output shaft supports on output shaft speed nut (Speednut) axial restraint with one with firmlying in other words, this speed nut or be embedded in the groove of output shaft or carved indenture on smooth.Another kind of possible scheme is: output shaft covers starting operation at the retarder of a rigidity.
By the DE 103 43 168 A1 windshield wiper engine of a kind of wiper device of cicada, in this electrical motor, be provided with a seal ring and be used to seal the passage that output shaft passes a bearing carrier ring, this seal ring is contained in the expansion of bearing hole of bearing carrier ring.Also be provided with a cover plate in order to cover in seal ring, it is designed to peviform, that is to say a bottom and a circle wall.The bottom has a hole to be used to pass output shaft.This cover plate that makes the pressure injection part of being made up of Plastic Parts is installed like this, makes it be fixed on one in its perforate position on retarder case member upper surface by rigid fit, and has the projection of the perforate that is used for bearing carrier ring.
By EP 0 977 680 B1 are also known a kind of wiper device arranged, it has a Wiper bearing, one of Windshield Wiper is bearing in axle drive shaft axially mounting in the bear box between a crank and starting board in this bearing, this starting board is axially fixed by a spring coil, and this spring coil enters in the groove of axle drive shaft.Free end with this axle drive shaft that stretches out in the retarder shell is connected with the over cap anti-rotation ground that plastics are made, this over cap in the assembly method upper support on spring coil.
Summary of the invention
The over cap that is provided with starting face according to the present invention is made by steel plate and is contained in force fit that this stretches out in the retarder vault; on portion's section of non-incision; wherein so select force fit, to such an extent as to over cap time acts on maximum axial force output shaft on greater than this in operation at the minimum tractional force on the output shaft.
Steel plate is anti abrasive on the one hand, to such an extent as to starting face (Aulauffl
Che) can realize enough service life, the steel plate permission has enough force fits on the other hand with finding no fault with, and this length of life that is force-fitted in has guaranteed output shaft failure-free axial restraint, especially material and be provided with to be subjected to tangible timeliness.Here just it is also noted that: force fit is so selected so that the ground over cap at the minimum tractional force on the output shaft greater than the axial force that the time is occurred in operation.
Satisfying two kinds of functions according to over cap of the present invention, is exactly the function of over cap and the function of spring coil, has wherein avoided carving in output shaft groove in an advantageous manner, therefore makes output shaft that higher intensity be arranged.Also simplified assembling in addition, the notch stress concentration effect that has reduced the complexity of axle drive shaft and avoided causing under certain condition owing to the speed nut groove that on axle drive shaft, is provided with.
Over cap can be made by deep-draw simply and have a cylindrical part that surrounds output shaft more aptly at the force fit position, and this part closely and be fixed on and abut on the output shaft.The length of cylindrical part can be coordinated with needed displacing force.Cover the retarder vault and have an axial and overlapping bead of retarder vault at end face according to a kind of design plan over cap of the present invention in addition.Therefore bearing space is protected, prevented injection water, this injection water in the axial direction or favour axial direction and be sprayed onto on the over cap.
Description of drawings
Other advantage is seen following the description of the drawings.One embodiment of the present of invention have been represented in the accompanying drawings.Accompanying drawing, specification sheets and claims have comprised many combined feature.The professional person is also these features of study tour and they are aggregated into reasonably other combination individually more aptly.Accompanying drawing is depicted as:
Fig. 1: the local vertically diagrammatic cross-sectional view of a retarder vault.
Fig. 2: the longitudinal sectional view of over cap.
The specific embodiment
Just expressed a part of windshield wiper engine about wiper device 10, it is an electrical motor that has retarder, and its retarder includes a gear 16, and this gear is fixedly located on the end of output shaft 18 and drives this axle.Output shaft 18 is arranged on 14 li on the retarder vault of retarder shell 12 by means of bearing 20,22. Bearing 20,22 can be designed to plain bearing or antifriction-bearing box and be bearing in one direction on the outer shell flanch 34 of retarder vault 14.Axially abut at another direction head bearing 22 on the flange 36 of gear 16, and output shaft 18 is being bearing on the end face side of retarder vault 14 by an over cap 26 on another bearing 20 in other words at the end face side bearing.
Over cap 26 has a starting face 30 for this purpose, and it starts on the end face of retarder vault 14 or bearing 20 with this starting face.The over cap of being made by steel plate 26 has a cylindrical part 28, and it equally also is on columniform the section 38 that this part is fitted in of output shaft 18 with force fit, and this section is stretched out for 14 li from the retarder vault.Select the position of over cap 26, make that distance 40 permissions between the end face of the opposed layout of the starting face 30 of over cap 26 and retarder vault 14 have enough cod gaps.Having a bead 32 to be arranged on the over cap 26 on the radially outward edge of starting face 30, this bead and retarder vault 14 have in the axial direction one section overlapping.Portion's section 38 transits to an axle journal 24 by a bevelled part, can fix a unshowned crank on this axle journal.
