The specific embodiment
Come further explain the present invention below in conjunction with specific embodiment and accompanying drawing.
Referring to Fig. 1 to Fig. 5; Said vehicle electric power-assisted steering device casing comprises that be connected with vehicle steering direction of passage axle and hollow main box 1 can the ccontaining retarder that is connected with steering column for vehicles in it; This main box 1 is provided with motor mount 2 and controller mount pad 18; Said motor mount 2 is a hollow box body, and this motor mount 2 intersects and intracavity inter-connection with said main box 1.
The vehicle electric power-assisted steering device tank body blank that the present invention relates to is by the aluminum alloy materials die cast.Particularly, can each parts refill behind the die cast respectively and be assigned in one, also can all parts one die casts.Pattern draft maximum during die casting is with 1.5 ° of calculating, and promptly pattern draft is not more than 1.5 °.Such as, said motor mount 2 and said main box 1 one die cast; Perhaps said controller mount pad 18 one die casts.In this example, said controller mount pad 18 and main box 1 one die cast, and said motor mount 2 independent die casts are assemblied in these motor mount 2 machineries on the said main box 1 then.The concrete mounting means of said motor mount 2; Said main box 1 is provided with motor mount fixed orifice 17; The set-up mode that this motor installs and fixes hole 17 can form for being fixed on through the stirrup two ends on the main box 1; It is through machinework moulding after the die casting that preferred this motor installs and fixes hole 17; Said motor mount 2 uses dowel fixes to be positioned on the said main box 1 through this motor mount fixed orifice 17, for the location of strengthening pinning, on the above cooresponding position of pin pin-and-hole, said motor mount 2 surfaces, establishes depression 22; Strengthen the friction force between pin and motor mount 2 surfaces, the firm connection between assurance motor mount 2 and the main box 1.
For said motor mount 2; Referring to Fig. 1, Fig. 3 and Fig. 4; Said motor mount 2 is the tubular structure of an end closure, is provided with motor mounting flange 21 in the open end end of this motor mount 2, is used to install assist motor; 21 one-tenth ears shapes of this motor mounting flange, correspondence is provided with fastening screw on it.In order to guarantee the stable installation of assist motor, the end face 20 of said motor mounting flange 21 should keep smooth.Motor mount 2 internal cavities 23, be used for ccontaining assist motor mouth and with main box 1 in being connected between the retarder of installation.
For main box 1, referring to Fig. 1 and Fig. 2, said main box 1 inner hollow; Both ends open, the one of which end opening is provided with mounting flange 16, is used for being connected with automobile steering shaft end portion; This mounting flange 16 is three ear shapes; Each fixedly on the ear correspondence establish fastening screw, this main box 1 other end opening be for being connected of steering column for vehicles, specifically be that said Steering gear passes this end opening and the retarders that are installed in main box 1 inner chamber 15 are connected.The internal cavities 23 of motor mount 2 is connected with the inner chamber 15 of main box 1; See the phase port 11 among Fig. 1; Said assist motor links to each other with main box 1 interior retarder through this phase port 11 and does the moment transmission, passes to Steering gear, finally realizes turning to of automobile.
For controller mount pad 18,, on said controller mount pad 18, be provided with the intercommunicating pore 14 that is communicated to main box 1 inner chamber 15 referring to Fig. 5.This intercommunicating pore 14 can also be as resistance sensor or torque sensor are installed.
Vehicle electric power-assisted steering device casing in this example is in assembling; The retarder that has built-in sensors is installed in main box 1; Assist motor is installed on the motor mount 2 and makes it and is connected with main box 1 interior retarder then; Installation and control device on controller mount pad 18, this controller links to each other with assist motor, can be through intercommunicating pore 14 at main box 1 interconnector.This deflector is installed between axis of orientation and the Steering gear of automobile and gets final product.
The present invention is work like this, and referring to shown in Figure 6, operator's steering wheel rotation drives its bonded assembly axis of orientation, is detected the size and Orientation that is applied to the torsion on the axis of orientation and is passed to controller by the built-in torque sensor of retarder.Controller is according to the signal value of this torsion; And combine the real-time speed of a motor vehicle, at this, the real-time speed of a motor vehicle detects the speed of automobile by vehicle speed detector device and is delivered in the controller; Or signal value such as engine speed compares calculating, gives assist motor or motor correspondent voltage value then.Motor is after energising, and the output corresponding torque is delivered to through retarder on the Steering gear of automobile, thereby has realized turning to of automobile, drives lighter.
More than the technical scheme that the embodiment of the invention provided has been carried out detailed introduction; Used concrete example among this paper the principle and the embodiment of the embodiment of the invention are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the embodiment of the invention; Simultaneously, for one of ordinary skill in the art, according to the embodiment of the invention, the part that on the specific embodiment and field of application, all can change, in sum, this description should not be construed as limitation of the present invention.
