Fig. 2 is the lateral plan of Fig. 1;
Fig. 3 is a semi-sictional view structural representation of the present utility model.
Among the figure: the 1-motor; The 2-steering box; The 3-change-speed box; The 4-universal driving device; Swing arm under the 5-; The 6-shock absorber; The 7-steering swivel; The 8-brake disc; 9-wheel rim butt flange; The 10-hub bearing.
The specific embodiment
Further specify the utility model below in conjunction with Figure of description.
As shown in the figure, a kind of superminiature low speed pure electric automobile front driving axle, comprise preceding bridge grider, be symmetrical arranged motor 1 on the preceding bridge grider, two motor 1 one ends link to each other, the other end is the change-speed box 3 of captive joint employing planetary gear speed-reduction respectively, and motor 1 and change-speed box 3 have constituted the main body of drive system jointly.The bottom of motor 1 fixedly installs the motor bearing that suspends, and the motor bearing that suspends suspends by the rubber block that is provided with and is arranged at preceding bridge grider, and whole drive system be supported on by 4 rubber blocks that suspend before on the bridge grider.The mouth of change-speed box 3 connects universal driving device 4 by spline, universal driving device 4 other end sockets are provided with steering swivel 7 backs and connect wheel rim butt flange 9 by spline, between steering swivel 7 and the wheel rim butt flange 9 hub bearing 10 is set, captive joint brake disc 8 on the wheel rim butt flange 9, on the wheel rim butt flange 9 tyre and rim is installed, universal driving device 4 drives the rotation of wheel rim butt flange 9, thereby makes tyre rotation.Steering swivel 7 is directly inserted in shock absorber 6 lower ends, fixes shock absorber 6 by the bolt on the locking steering swivel 7, and the upper end adopts ramuscule post assembly to link to each other with vehicle body.Steering box 2 is fixed on the vehicle body by clip, and two ends link to each other with steering swivel 7 arms by the ball pin.Following swing arm 5 one ends link to each other with steering swivel 7 by the ball pin, and the other end links to each other with vehicle frame by bolt.
The utility model overcomes traditional car front driving axle system because the shortcoming that Heavy Weight, bulky, complex structure etc. can not directly be adopted by superminiature low speed pure electric automobile, 1) power drive system adopts double-motor 1 install in series, planetary gear speed-reduction, electronic differential; Motor 1 outer casing bottom is processed with the motor bearing that suspends, and on the bridge grider, power was delivered to wheel through universal driving device before whole drive system was supported on by 4 rubber mountings; 2) suspension adopts follow-on MacPherson type, and traditional McPherson strut has many thrust leverages such as laterally vertical, and the utility model propelling rod adopts swing arm 5 designs under the A word, can play horizontal and vertical propelling rod effect simultaneously; Because superminiature low speed pure electric automobile speed is low, light weight, during turning inclination little, the utility model adopts removes the Panhard rod design; Jounce bumper 6 designs have absorbed vehicle shock absorber and damper of motorcycle advantage separately simultaneously, shock absorber 6 adopts the small size of damper of motorcycle, constructional simple design, the lower end adopts plug-in type to be installed on the steering swivel 7, the upper end adopts small size upper supporting column assembly to link to each other with vehicle body, spring adopts the motor spring rigidity Design, and reduction spring diameter and middle warp, reduces the spring size; Like this, the McPherson suspension through remodeling still quantitatively all reduces from rod member greatly from weight; 3) traditional automobile steering knuckle, propons brake system adopt steel to forge or casting more, are all designing requirements of miniature head and shoulders above low speed electronlmobil on bulking value or the required braking force.The utility model steering swivel 7 adopts aluminium matter alloy material die cast, and brake disc 8 adopts the punch forming of attenuate steel plate, has played the weight-saving effect.
