Description

The special-purpose two shaft with key way wheel hub motors of a kind of electric automobile
Technical field
The utility model belongs to the electric automobile field, relates to the special-purpose two shaft with key way wheel hub motors of a kind of electric automobile.
Background technology
Adopt the wheel hub motor driven vehicles, can save engine and drive system, reduce the loss of power in transmittance process, can improve Energy Efficiency Ratio.At present, the most power modes that drive with wheel hub motor that adopt of electric automobile.But wheel hub motor is of a great variety, wheel hub motor simple in structure but serviceability is poor, advanced in performance wheel hub motor but complex structure.But, the advance that wheel hub motor drives has determined it to be in critical role in the electric automobile development, therefore, needs a kind of wheel hub motor simple and practical, dependable performance to address that need.
Summary of the invention
Purpose of the present invention is exactly to be to overcome above-mentioned deficiency of the prior art and a kind of special-purpose two shaft with key way wheel hub motors of electric automobile of simple in structure, dependable performance are provided.
For achieving the above object, the utility model is to adopt following scheme to be achieved in that the special-purpose two shaft with key way wheel hub motors of a kind of electric automobile, comprise motor shaft (1), shell (2), motor cabinet (3), it is characterized in that: shell (2) is provided with set bolt (4), the outside is provided with wheel connecting bolt (10), the two shaft with key way wheel hub motors (5) of two keys are fixed on the support (3), support (3) is provided with bearing (6), outside framework oil seal (7) is located between motor shaft (1) and the bearing (6), and link keyway (8), mechanical lock dead key groove (9) are arranged on the motor shaft (1).
The utility model is simple in structure, and dependable performance is installed easy-to-connect, and than the speed governing of change machine and the complicated control that are easier to realize to wheel hub motor, perfect heat-dissipating is a kind of wheel hub motor of dependable performance.
Description of drawings:
Fig. 1 is the utility model structural representation
Embodiment:
The outer end of motor shaft is provided with outer flat key and screw thread, and the multipurpose bolt is equipped with in the outside of shell, and is installed in outside end cap, and outboard end covers and is provided with positioning step, and the both sides of shell are provided with the motor cabinet vertical with motor shaft.The flat key of motor outer end is equipped with the wheel connector by locking nut, and motor shaft is provided with keyway, and it is locked to carry out machinery to locking nut, and motor cabinet is provided with wheel bolt.The wheel connecting bolt is connected with wheel; Bearings at both ends guarantees the axiality of motor, makes motor rotation steady; Bearing is located on the motor cabinet, is used for the support motor axle; Outside framework oil seal has guaranteed the dustproof and waterproof of motor; The keyway and the elevation angle, the supporting use of back axle prevent that motor shaft from radially rotating; Brake pad is used for locked hold-down nut by locked keyway, has guaranteed that motor is connected effect with back axle, the elevation angle.
