Abstract
The utility model relates to a hub motor fixing mode. The hub motor fixing mode comprises a hub motor assembly, a hub motor outer rotor, a hub motor inner stator, a brake disc and a rear axle head support, wherein the hub motor outer rotor, the hub motor inner stator, the brake disc and the rear axle head support are arranged on the hub motor assembly. A connecting spacer is arranged between the rear axle head support and the brake disc, and a through hole for the hub motor inner stator to penetrate is formed in the center of the connecting spacer. A hub unit is eliminated. In a hub motor, a rotating shaft is connected with the connecting spacer through a flat key, then the connecting spacer is fixed with the rear axle head support, and the hub motor can be connected with a brake assembly reliably. The hub motor fixing mode is compact in structure, low in cost and easy to maintain, and meanwhile, parts are reduced.
Description
Technical field
The utility model relates to the automotive hub motor, relates in particular to a kind of wheel hub motor fixed form.
Background technology
Can realize the 4 wheel driven mode activated by rear axle being installed additional wheel hub motor for traditional forerunner's automobile, and when low speed such as city operating mode are driven a vehicle, only drive the purpose that vehicle reaches fuel-economizing with wheel hub motor by killing engine.Wheel hub motor generally all is driving and the braking that is assembled together to realize vehicle with drum brake mechanism.And how to realize that for plate disc brake high convenience is installed, high reliability connects is the subject matter of pendulum in face of us.When traditional precursor vehicle trailing wheel being carried out the wheel hub motor installation, require not change original plate disc brake and suspension frame structure form substantially, and will be easy to dismounting and maintenance.
Chinese patent notification number CN 202488225 U, October 10 2012 day for announcing, name is called disc type electric machine, comprise base, be fixed on shell on the base, be arranged on the rotor disk of enclosure, described shell comprises interconnective stator dish and the following stator dish gone up, and upper and lower stator dish cooperates the body that constitutes flats; Fixedly there is the magnetic pole of the stator rotor disk the corresponding inboard of upper and lower stator dish for circular, and rotor disk radially comprises hub-like terminal pad, track and the rotor magnetic pole seat of the hollow out that is connected successively from the center of circle; The terminal pad middle part is axle sleeve, and axle sleeve cooperates with upper and lower stator dish by bearing; The rotor magnetic pole seat is annular arrangement; Fixedly there is the rotor magnetic pole corresponding with magnetic pole of the stator on rotor magnetic pole seat two sides.Its weak point is that wheel hub motor can only be connected with drum brake mechanism mostly, and protection face is narrow; Wheel hub motor then needs wheel hub motor internal stator axle is made the male splines form as if linking to each other with plate disc brake, and hub inner wheel hub axle is made the female splines form, links to each other by interior male splines form at last, is difficult for processing, and cost is higher.
The utility model content
The purpose of this utility model is to link to each other with plate disc brake and then need wheel hub motor internal stator axle is made the male splines form in order to solve existing wheel hub motor, hub inner wheel hub axle is made the female splines form, link to each other by interior male splines form at last, be difficult for processing, the defective that cost is high and provide a kind of facility is installed, be easy to the wheel hub motor fixed form of dismounting and maintenance.
To achieve these goals, the utility model is by the following technical solutions:
A kind of wheel hub motor fixed form, comprise the wheel hub motor assembly, be arranged on wheel hub motor outer rotor, wheel hub motor internal stator, brake disc and back end of the bridge bearing on the wheel hub motor assembly, be provided with between described back end of the bridge bearing and the brake disc and be connected pad, connect the pad center and be provided with the through hole that passes for the wheel hub motor internal stator.In the technical program, back end of the bridge bearing be connected the pad captive joint, the wheel hub motor internal stator passes the through hole that connects pad and is connected with back end of the bridge bearing then, in motion, the vibration on road surface with impact by the wheel hub motor internal stator be connected pad, then through after the end of the bridge bearing pass to whole rear-suspension system, cancelled hub, in wheel hub motor rotating shaft by flat key be connected pad and link to each other, connect pad and fix with back end of the bridge bearing, still can be connected with brake assembly reliably at cancellation hub rear-wheel hub motor like this, parts are less, compact conformation, cost is low and be easy to safeguard.
As preferably, the wheel hub motor internal stator by flat key be connected pad and connect.
As preferably, the size of through hole and wheel hub motor internal stator match.
As preferably, brake disc is connected by bolt with the wheel hub motor outer rotor.
As preferably, connect pad be provided with some for the fixing bolt hole of back end of the bridge bearing.
The beneficial effects of the utility model are, the utility model has been cancelled hub, in wheel hub motor rotating shaft by flat key be connected pad and link to each other, connecting pad fixes with back end of the bridge bearing again, wheel hub motor still can be connected with brake assembly reliably, parts are less, compact conformation, and cost is low and be easy to safeguard.
