Embodiment
The utility model embodiment provides a kind of electric chassis, using wheel hub motor and independent steering motor, structure
It is compact, turn to flexibly, while rectangular axes steering component is employed, so steering motor is horizontally disposed, and it is highly relatively low, solve
Existing crusing robot turns to underaction, and steering mechanism and walking mechanism are complicated, the larger technical problem of space-consuming.
To enable goal of the invention of the present utility model, feature, advantage more obvious and understandable, below in conjunction with this
Accompanying drawing in utility model embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, and shows
So, the embodiments described below are only the utility model part of the embodiment, and not all embodiment.Based on this practicality
Embodiment in new, all other reality that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example is applied, belongs to the scope of the utility model protection.
Referring to Fig. 1, a kind of one embodiment of electric chassis is provided in the utility model embodiment, including：OK
Walk mechanism and steering mechanism；
Walking mechanism includes：Wheel hub motor 4 and tire；
Wheel hub motor 4 is arranged in tire；
Steering mechanism includes：Steering motor 1, rectangular axes steering component 2 and steering spindle 3；
The power end of steering motor 1 is fixedly connected with the power intake of rectangular axes steering component 2；
The clutch end of rectangular axes steering component 2 is fixedly connected with one end of steering spindle 3；
The other end of steering spindle 3 is fixedly connected with the reversing shaft of wheel hub motor 4.
It should be noted that the present embodiment uses wheel hub motor 4 and independent steering motor 1, the technology of wheel hub motor 4 also by
Referred to as wheel inner electric machine technology, its maximum feature exactly all integrate power set, transmission device and brake apparatus
Into wheel hub, be able to the mechanical part of electric chassis is greatly simplified, it is compact-sized, turn to flexible, while employ rectangular axes
Commutate component 2, so steering motor 1 is horizontally disposed, highly relatively low, spatial altitude occupancy is small, solves existing inspection machine
People turns to underaction, and steering mechanism and walking mechanism are complicated, the larger technical problem of space-consuming.
Further, based on rectangular axes steering component 2 hypoid gear that, driven gear axis antarafacial is vertical slows down
Machine.
It should be noted that in hypoid gear reductor driving gear shaft relative to driven gear shaft have upwards or to
Under skew (correspondingly be referred to as upper offset or below-center offset), when offset it is big to a certain extent when, a gear shaft can be made from another
By one gear shaft by, thus can each gear both sides arrange compact dimensions bearing, for enhancing support stiffness,
Ensure gear teeth correct engagement, be very beneficial so as to improve gear life, the journal offset of hypoid gear pair causes its active
Gear helical angle is more than driven gear helical angle, though therefore hypoid bevel wheel it is secondary normal module it is equal, transverse module
It is not wait (transverse module that the transverse module of driving gear is more than driven gear), this causes the master of accurate two-sided Bevel Gear Transmission
Moving gear has bigger diameter and more preferable strength and stiffness than the driving gear of corresponding Helical Bevel Gear, in addition, by
It is all larger in the driving gear diameter and helical angle of hypoid bevel wheel transmission, so that its Contact Stress of Gear reduces, the longevity
Life improves, and therefore, hypoid bevel wheel reductor is larger suitable for being driven, and requires larger to the strength and stiffness of reductor
Working environment.
Further, the reversing shaft of wheel hub motor 4 is single shaft；
The driven end of steering spindle 3 is L-shaped connecting lever.
Further, in addition to：Vehicle frame 5 and dividing plate 6；
Rectangular axes steering component 2 is fixedly connected with vehicle frame 5；
The dividing plate 6 is provided with to be fixedly connected for the through hole by the steering spindle 3, dividing plate 6 with vehicle frame 5.
It should be noted that dividing plate 6 can have protective effect with functions such as water proof and dust proofs to inside chassis structure.
Further, in addition to：Bearing 7；
The bearing 7 is arranged between the dividing plate 6 and the steering spindle 3, and the bearing 7 and the steering spindle 3 are coaxial
Set.
It should be noted that bearing 7 plays radial constraint displacement to steering spindle 3.
Further, in addition to：The shell of steering motor 1；
The shell of steering motor 1 is fixedly connected with rectangular axes steering component 2.
Referring to Fig. 1, a kind of second embodiment of electric chassis, second reality are provided in the utility model embodiment
The difference for applying example and one embodiment is：
Based on rectangular axes steering component 2, driven gear axis intersect vertical spiral bevel gear speed reducer.
It should be noted that spiral bevel gear speed reducer is due to the overlapping influence in gear teeth end face, at least more than two pairs
The gear teeth engage simultaneously, and therefore, spiral bevel gear can bear larger load, and its gear teeth is not in full tooth length while nibbled in addition
Close, but the other end is continuously gradually turned to by one end of tooth so that its stable working, when running at high speed, noise and shake
Dynamic and very little, in addition, when gearratio is smaller, the driving gear of accurate two-sided Bevel Gear Transmission is relative to spiral bevel gear
Driving gear just seems excessive, at this moment more reasonable from spiral bevel gear.
Further, the reversing shaft of wheel hub motor 4 is double shafts；
The driven end of steering spindle 3 is fork-shaped connecting lever.
It is apparent to those skilled in the art that for convenience and simplicity of description, the system of foregoing description,
The specific work process of device and unit, the corresponding process in preceding method embodiment is may be referred to, will not be repeated here.
Described above, above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although ginseng
The utility model is described in detail according to previous embodiment, it will be understood by those within the art that：It is still
Technical scheme described in foregoing embodiments can be modified, or which part technical characteristic is equally replaced
Change；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the utility model technical scheme
Spirit and scope.
