Detailed Description

As shown in fig. 1, the driving device with steering function provided by the present invention is mounted on a floor 1 of a vehicle body, and as shown in fig. 2, the driving device includes a differential 2 driven by a second motor 6, and the differential is of a conventional structure, i.e., includes a transmission shaft 21, a pair of axle shafts 23, a driving gear 22, a planetary gear and an axle gear.

As shown in fig. 2, a mounting plate 3 parallel to the bottom plate 1 is fixedly connected to the lower end surface of the bottom plate 1, a steering structure 4 is fixedly connected to the lower end surface of the mounting plate 3, an actuating structure 5 fixedly connected to the bottom plate is arranged on one side of the steering structure 4, the steering structure 4 includes a steering cylinder 41, the differential 2 is arranged in the steering cylinder 41, the two half shafts 23 respectively penetrate through the steering cylinder, the steering cylinder is provided with two bearings, and the two half shafts are respectively butted on the two bearings; the driving gear 22 is transversely arranged below the bottom plate, and the transmission shaft 21 is perpendicular to the bottom plate.

As shown in fig. 2-4, the steering structure includes a pivoting support 42, the pivoting support 42 is fixedly connected below the mounting plate 3, and the steering cylinder 41 is fixed below the pivoting support, so that the actuating structure 5 causes the movable end of the pivoting support 42 to rotate, which in turn causes the steering cylinder to rotate under the pivoting support, so that the rotating cylinder 41 rotates the differential, which in turn causes the wheels to steer.

Further, as shown in fig. 2, a pinion 51 is engaged with the slewing bearing, a driving shaft 52 penetrating through the mounting plate and the base plate is connected to the pinion, and the top end of the driving shaft 52 is abutted against a first motor 53 mounted on the base plate, so that the rotation of the pinion is promoted by the first motor, and the slewing bearing is driven to rotate.

As shown in fig. 4, the mounting plate 3 is preferably rectangular, screw holes 31 are formed at four corners of the mounting plate, connection holes are formed at positions corresponding to the base plate 1, so that the mounting plate 3 can be connected to the lower end surface of the base plate 1 through bolts, a circular hole corresponding to the center hole of the slewing bearing 42 is formed at the middle position of the mounting plate, and a threaded hole is formed around the circular hole at the middle position of the mounting plate to correspond to the connection hole of the slewing bearing, so that the mounting plate is connected to the slewing bearing.

The shape of the steering column 41 is not limited to this, and the intermediate slewing bearing 42 may be configured as a chain.

The working principle is as follows: when the steering is not needed, the differential mechanism is driven to rotate by the second motor and then is transmitted to the half shaft; when the steering is needed, the first motor drives the pinion to start rotating, the pinion drives the slewing bearing to rotate, the steering cylinder is driven to rotate, the differential mechanism is finally rotated, and the steering is achieved.
