Detailed Description
The present invention will be further described with reference to the following specific embodiments.
It is to be understood that the terms "central," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the description of the invention based on the orientation or positional relationship shown in the drawings for convenience in describing the invention and for simplicity in description, and are not intended to indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be considered limiting.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, terms appearing as "mounted," "connected," and "connected" are to be construed broadly, e.g., as being fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
A freely steerable tractor wheel comprising:
the rotary gear is used for being fixedly connected with a suspension system of the tractor;
the rotary gear mounting disc is in rotary fit with the rotary gear by taking the axis of the rotary gear as a central line;
the wheel mounting frame is fixedly connected with the rotary gear mounting disc, and wheels are mounted on the wheel mounting frame and are in running fit with the wheel mounting frame by taking the axis of the wheel mounting frame as the center;
the rotary driving gear is driven by a rotary motor fixed on a rotary gear mounting disc to rotate by taking the axis of the rotary motor as the center, and the rotary driving gear is meshed with the rotary gear.
A walking driving motor is installed on one side of the wheel installation frame, wheels are installed on the other side of the wheel installation frame, a driving shaft of the walking driving motor is fixedly connected with the wheels, and the axis of the driving shaft is overlapped with the axis of the wheels.
More specifically, as shown in fig. 1, the rotary gear 1-3 is fixedly connected to the suspension system, that is, fixedly connected to the chassis of the tractor through the suspension system, and more specifically, the rotary gear 1-3 is fixedly connected to the suspension movable block of the suspension system, (the suspension system generally includes a fixed portion fixedly connected to the chassis and a movable portion slidably engaged with the fixed portion, which is referred to as the suspension movable block for short, as shown in fig. 2), so that the rotary gear is fixed to the tractor in the horizontal direction, and the connection manner can be achieved through screws, bolts and the like, so as to facilitate disassembly, and when the disassembly problem is not considered, the rotary gear can be fixed by direct welding and the like.
For the design scheme, the bearing and the shaft in the prior art can be referred to, and therefore the design scheme is not shown in detail in the drawing. And the connection relationship of the rotary gear and the components on the rotary gear mounting disc is also replaced mutually. For example, the bearing is mounted on a rotary gear mounting plate, and the fixed shaft is mounted on a rotary gear.
The rotary motor 1-1 is fixed on a rotary gear mounting disc, a driving shaft of the rotary motor 1-1 is fixedly connected with a rotary driving gear 1-2, in the scheme, the gear is in a standard specification, the axis of the driving shaft of the rotary motor 1-1 is coincided with the axis of the rotary driving gear 1-2, and when the rotary driving gear 1-2 rotates, the rotary driving gear rotates relative to the rotary gear due to the fact that the rotary gear is not moved and the rotary driving gear is meshed with the rotary gear, namely the rotary gear mounting disc rotates relative to the rotary gear 1-3, namely the rotary gear mounting disc rotates relative to a vehicle body chassis. The wheels 1-5 are mechanically connected with the rotary gear mounting disc 1-4 into a whole through the wheel mounting frames 1-6. Therefore, when the rotary electric machine 1-1 rotates, the wheels 1-5 rotate at an arbitrary angle with respect to the tractor chassis (slewing gear). The four wheels of the tractor are all the freely steering tractor wheels. On the same principle, other three wheels of the tractor can rotate at any angle relative to the chassis of the tractor, and the rotation of the four wheels is independent and does not interfere with each other. The walking driving motors 1-7 can rotate in forward and reverse directions, and each wheel of the tractor is provided with one walking driving motor 1-7 to finish the walking of the tractor.
Wherein, the rotary driving gear is not contacted with the rotary gear mounting disc, thereby avoiding the interference.
Turning is realized: when the vehicle needs to turn, the rotating motor driver controls the turning motor 1-1 to rotate, and drives the rotating driving wheels 1-2 to rotate, so that the steering of the wheels is realized.
The walking is realized: when the vehicle needs to go forward or backward, the stepping motor driver controls the walking driving motors 1-7 to rotate, and drives the wheels 1-5 to rotate, so that the tractor walks.
It will be apparent to those skilled in the art that modifications and variations can be made in the above-described embodiments, or some features of the invention may be substituted by equivalents, without departing from the spirit or scope of the invention.
