Abstract

The invention relates to a pump drive motor fastened to a housing of a hydraulic pressure device. To connect a machine to a unit casing at a low cost and quickly, the fastening portion of a pump drive motor projects into an all-round recess, then assuredly and/or frictionally fastens to the housing by deforming the materials.

Description

Be connected with the device of pump drive motor on the housing
The present invention relates to be connected with on a kind of its housing the device of pump drive motor.
This class device can be ABS (locking braking device) or ASR (adhering to a control) device for example, and its housing is that the hydraulic cylinder by this class device constitutes.
Up to now, utilize screw or bolt and nut is the usual practice on housing with the pump drive motor spiral shell knot of this type of device always.This connecting means is imperfect, because it needs independent union piece and need to provide screw thread on housing or pump drive motor.Between erecting stage pump drive motor spiral shell knot is also being needed holding time on device case.
According to the present invention, a kind of device that is connected with pump drive motor on the housing that is used at least one pump and its housing that has is provided, it is characterized in that, pump drive motor has at least one and connects partly, by should connecting partly and/or housing distortion, and pump drive motor is connected on the device case by this attachment portion; The motor casing of attachment portion and pump drive motor is made into integral piece.
Device of the present invention with above-mentioned feature has following advantage: owing to eliminated independent union piece, pump drive motor is economical with being connected of housing.
Explain the present invention in detail below with reference to two representative instances shown in the drawings.
Two width of cloth figure represent the sectional view of apparatus of the present invention example at connection part.
Fig. 1 represents the partial sectional view by apparatus of the present invention of the total representative of label 10.Pump drive motor 12 is installed on the wall of housing 14 of device 10 from the outside.
Motor 12 has a motor drive shaft 16, one rotor windings 18 dresses thereon.Motor drive shaft 16 is rotatably mounted by two ball bearings 20, but can only see a bearing among the figure, and one of two ball bearings 20 embed in the housing lid 22 of pump drive motor 12, and the some of this lid is being sealed motor casing 24 at an end of the housing 14 of facing device 10.
Face an end of device case 14 at it, empty tubular motor casing 24 stretches out outside the motor casing lid 22 vertically.Stretching out of motor casing 24 partly forms a whole connection part 26 of enclosing, and connects partly 26 end regions 28 bendings and gets up, and forms the whole circle flange that a radially outward stretches out.
Pump drive motor 12 leans against the outside of device case wall 14 by its motor casing lid 22, and it connects partly and 26 stretches in the circular groove 30 that forms in device case wall 14.Radially inwardly stretch into and overlap bending get up to form flange motor casing 24 connection partly the whole circle on 26 the end regions 28 fixedly lip 32 go into mode by rolling and form.Like this, pump drive motor 12 just is connected on the device case 14.This is connected on the whole circumference of motor casing 24 and works, its result, retention force is evenly distributed, can not produce stress at indivedual tie point places, the mode of utilizing it to form on large size and distributing along whole circumference, this kind connection also can be transmitted big retention force between device case 14 and motor 12.
Motor casing 24 utilize in the embedded groove 30 seal ring 34 and relatively device case 14 seal.
Fig. 2 represents second embodiment of apparatus of the present invention 10.Wherein, pump drive motor 12 has been done improvement more with being connected with the embodiment who is shown in Fig. 1 of device wall 14.In others, the device 10 that is shown in Fig. 2 has identical structure with the device that is shown in Fig. 1.For avoiding repetition, only an explanation is done in the embodiment's that is shown in Fig. 1 relatively variation below with reference to Fig. 2.Corresponding label is used for identical part.In addition, also may mention the explanation of doing with reference to Fig. 1.
In the embodiment of the apparatus of the present invention 10 that are shown in Fig. 2, empty tubular motor casing 24 stretches out outside the motor casing lid 22 of this end that is installed in motor casing 24 at its end that faces device case 14.This of motor casing 24 stretches out and partly forms empty tubular connection part 36, and this connection part 36 forms full circle and stretches in the circular groove 38 that forms in device case 14 with very little gap.Connect partly 36 and be provided with on its excircle by being pressed into the groove 40 that mode forms, a plurality of these grooves are the axial adjacent one another are of motor casing 24 and be distributed in several position place around circumference.The material deformation of device case 14 is got to enter these grooves 40.This has just caused certain friction to connect between motor 12 and device case 14.
In being shown in the embodiments of the invention of Fig. 2, the material of device case 14 enters the distortion of motor casing 24 and finishes by in the direction of arrow F device case 14 being pounded the limit in this hull outside.Pounding edge work can carry out along whole circumference or circumferential some independent place, in all cases all should the connection of motor casing 24 partly on 36 the each point place of fluted 40 circumference pound edge work.Pound the limit and will on device case 14, produce notch 42.
Pump drive motor 12 is put lean against on the device case 14 before, also promptly before the connection of pump drive motor 12 is partly in the circular groove 38 in the 36 inletting device housings 14, previous sealed compound 44 sprays in the circular groove 38, so that after motor 12 is installed motor casing 24 relative device cases 14 are sealed.
If the strength of desired fixing motor 12 is less, it can not the connection part 26 that full circle ground forms two embodiments of the present invention, 36, but can dispersedly tongue be distributed in the circumference that axially stretches out from that end that faces device case 14 of motor 12 around and it is stretched into the groove of device case 14, utilize again as pound the limit to make it frictionally and/or positively be fixed on the there.
Device case can be a pump case, also can be the hydraulic cylinder of locking braking (ABS) system or adhering to control system (ASR).
The foregoing description, owing to eliminated independent link, joint construction is economical.In addition, connection can be carried out rapidly, thereby is very suitable for automation.The connection of apparatus of the present invention can constitute between pump drive motor and housing and is connected reliably, and need not to prevent to throw off voluntarily.To definitely avoid motor being pulled down and being reconnected subsequently from housing by without permission people, thus to definitely avoid unsuitable do with.For ABS or ASR device,,, need to take some measure probably promptly for security reason for guaranteeing its operation.
