Shape groove, the external diameter of described back-up ring are the 0.82-0.9 of body diameter.Annular groove is installed for sealing ring to play sealing waterproof
Effect, back-up ring Position Design is reasonable, and it not only acts as iris action, and back-up ring plays guide effect when assembling, back-up ring it is outer
Wall contact motor casing inwall is easy to motor casing to be inserted in complete to assemble.
In the rear end cap of above-mentioned this heavy-duty car direction assist motor, the outer wall of described body offers several
Circumferentially be uniformly distributed and axially through arc-shaped slot.Arc-shaped slot for fixed screw screw mandrel positioning, in installation process
The positioning of fixed screw screw mandrel is firm, easy for installation.
In the rear end cap of above-mentioned this heavy-duty car direction assist motor, the inner face of described body has a corral
Around the notch of bearing mounting groove and the extension of axially projecting setting, described extension is coaxially disposed and prolonged with bearing mounting groove
The internal diameter in long portion is equal to the diameter of bearing mounting groove.Extension adds bearing mounting groove and the contact area of bearing, enhances
Support effect, there is provided motor job stability.
Compared with prior art, of the present utility model reasonable in design, space availability ratio is high, enables to motor overall
Small volume, and arrangement is easily installed, selve support effect is good, working stability, suitable on the assist motor of heavy-duty car direction.
