Description
Technical field
The utility model relates to a kind of wheel hub for pure electric automobile and drives the mounting structure with vehicle frame.
Background technology
In recent years, along with economic development, the progress of technology, the quantity that has of worldwide vehicle significantly rises, and causes traffic jam contaminated environment, and at present pure electric automobile is subject to the favor of people because of its energy-saving environment-friendly zero-emission.But current pure electric automobile is placed into by the electrical motor of a relatively high power in original engine bin to substitute combustion engine, and follow-up mechanical drive train still exists, so words, when the transmission of power of electrical motor is to drive wheel, can consume on transmission system greatly, what be really delivered to drive wheel only can have about 30%, therefore the walking mileage of pure electric automobile is caused significantly to shrink, now invented the drive motor be arranged in rim to carry out Direct driver vehicle and advance, so just need not mechanical drive.But due to the rim of outward rotation type drive its structure be in the motor shaft stretched, to be connected with the installation of vehicle and existing structure changes, existing rim mounting structure cannot be continued to use again.The feature that therefore must drive according to the rim of outward rotation type redesigns new wheel hub driving and the mounting structure of vehicle frame.
Utility model content
The purpose of this utility model is that a kind of wheel hub for pure electric automobile drives the mounting structure with vehicle frame.The mounting structure that a kind of wheel hub for pure electric automobile of the utility model design drives, comprise wheel hub, brake disc, wheel hub motor, hollow suspension bridge, it is characterized in that: in rim inner chambers, coaxial outward rotation type wheel hub permanent-magnet brushless DC electric machine is installed, the motor housing of outward rotation type wheel hub permanent-magnet brushless DC electric machine is bolted with rim and is connected, wheel hub motor aluminium core is installed in motor housing, wheel hub motor aluminium core is connected with wheel hub motor axle, motor housing side is provided with the motor machine end cap of closed outward rotation type wheel hub permanent-magnet brushless DC electric machine, the two ends of wheel hub motor axle respectively have bearing to connect motor housing and motor machine end cap, the drag drum of brake disc is fixedly connected with by axial thread with motor machine end cap, the brake pump of brake disc is fixed wallboard and is fixedly connected with by key with wheel hub motor axle.A pair external-expanding type brake plate of brake disc and extension spring and brake cylinder are arranged on brake pump and fix on wallboard, inside wheel hub motor axle, the front end of overhanging end is tapered column, the tapered column of wheel hub motor axle front end is nested in cone-shaped flange axle sleeve, and tighten up fixing also retaining by tight lock circle double nuts, permanent seat is welded with outside vehicle chassis hollow suspension bridge top, permanent seat and cone-shaped flange axle sleeve groove radial alignment, permanent seat and cone-shaped flange axle sleeve to be distributed screw axial restraint by cylindrical.
The utility model has the advantages that: stretch axle by rim motor, by simple structure cleverly, be reliably arranged on vehicle frame, ensure that pure electronic rim drives electric vehicle structure safety, dependable performance.
Accompanying drawing explanation
Accompanying drawing 1 is constructional drawing of the present utility model, and Fig. 2 is the construction profile schematic diagram of brake disc of the present utility model.
Detailed description of the invention
The mounting structure that in figure, a kind of wheel hub for pure electric automobile drives, comprise wheel hub 21, brake disc, rim motor 5, it is characterized in that: in rim inner chambers, coaxial outward rotation type wheel hub permanent-magnet brushless DC electric machine is installed, the motor housing 4 of outward rotation type wheel hub permanent-magnet brushless DC electric machine is fixedly connected with by bolt 27 with rim, wheel hub motor aluminium core 3 is installed in motor housing, wheel hub motor aluminium core connects wheel hub motor shaft 1 by key 24, motor housing side is provided with the motor machine end cap 6 of closed outward rotation type wheel hub permanent-magnet brushless DC electric machine, respectively there is bearing 2 at the two ends of wheel hub motor axle 1, 7 connect motor housing 4 and motor machine end cap 6, the drag drum 20 of brake disc is fixedly connected with by axial thread with motor machine end cap 6, the brake pump of brake disc is fixed wallboard 18 and is fixedly connected with by key 23 with wheel hub motor axle 1, a pair external-expanding type brake plate 19 and 30 extension spring of brake disc and brake cylinder 29 are arranged on brake pump and fix on wallboard, inside wheel hub motor axle 1, the front end of overhanging end is tapered column, the tapered column of wheel hub motor axle front end is nested in cone-shaped flange axle sleeve 17, and tighten up fixing also retaining by tight lock circle double nuts 12, permanent seat 16 is welded with outside vehicle chassis hollow suspension bridge 25 top, permanent seat 16 and cone-shaped flange axle sleeve 17 groove radial alignment, permanent seat 16 and cone-shaped flange axle sleeve 17 to be distributed screw axial restraint by cylindrical, 22 is tire, 8 is oil sealing, 9 is electric machine controller, 10 is motor cable.
The utility model make use of the feature that wheel hub drives, and utilizes a simple cone-shaped flange axle sleeve it to be connected with vehicle frame on the interior wheel hub motor axle stretched, and achieves structure simple, safe and reliable.
