Detailed Description
As shown in fig. 1-3, a steering gear for a special vehicle includes a land-based steering gear and a marine steering gear 9. The land steering transmission comprises a steering wheel 1, the steering wheel 1 being connected to a steering column 2, the steering column 2 being connected to a land steering mechanism 7 for steering the tyres of the amphibious vehicle. The land steering transmission mechanism further comprises an upper rotating angle sensor 5 for detecting the rotating angle of the steering wheel 1, the upper rotating angle sensor 5 is electrically connected with the controller 8, and under the water working condition, the controller 8 controls the water steering transmission mechanism 9 to steer through the signal of the upper rotating angle sensor 5. The upper rotation angle sensor 5 may be provided between the steering column 2 and the steering wheel 1. The existing land-based steering gear and marine steering gear 9 each have a steering wheel. The steering of the respective steering gear is controlled by the respective steering wheel. The steering wheel 1 of the invention shares the land steering transmission, and under the land working condition, the controller 8 can not control the water steering transmission mechanism 9 through the signal of the upper rotation angle sensor 5. When the steering wheel 1 rotates under the water working condition, the upper rotation angle sensor 5 sends the rotating angle to the controller 8, and the controller 8 controls the water steering transmission to rotate the corresponding angle. The above-water steering transmission mechanism can be preferably an electric hydraulic control mechanism, as shown in fig. 1, and comprises an electric hydraulic pump 90, wherein after the electric control pump 90 is connected with a steering signal of a controller 8, oil is supplied to a hydraulic loop of a spray pump, and the left and right rotation of a spray nozzle of the spray pump is realized through various structures; and the seawater pressurized by the jet pump is jetted out through the nozzle. The high-pressure water and the seawater form counter force to push the amphibious vehicle to turn. The above-water steering transmission mechanism is not provided with the existing steering wheel 1, but the rest is the prior art, and the detailed description is omitted, so that reference can be made to the comparison document of the background art, and other above-water steering transmission mechanisms in the prior art can also be adopted, and the above-water steering transmission mechanism is not limited to the structure in fig. 1. The land-based steering mechanism is a commonly used steering mechanism for automobiles and will not be described in detail.
The lower end of the steering column 2 is provided with a brake combining the working conditions on land and separating the working conditions on water, and the lower end of the brake is connected with a steering transmission shaft 70 of a land steering mechanism. If the same steering wheel 1 is used for operation under two working conditions, the situation that tires rotate synchronously along with the steering wheel 1 under the water working condition can occur, the tires rotate in water, the driving resistance is increased, the steering wheel is heavy to operate, a driver is easy to fatigue, and the driving stability in water is not facilitated, and when the water working condition is adopted, the tires can be prevented from rotating along with the steering wheel by separating the steering wheel 1 from the steering transmission shaft 70 by a brake or a clutch. The brake is a normally closed electromagnetic brake 4, the upper cover of the electromagnetic brake 4 is connected with the steering column 2, and the lower cover is provided with a transmission spline shaft 41, and the transmission spline shaft 41 is connected with a steering transmission shaft 70.
The steering column 2 is provided with a column driving mechanism 3 which can drive the steering column 2 to rotate; the land steering mechanism further includes a down-steering angle sensor 6 that detects the angle of rotation of the steering transmission shaft 70. The column driving mechanism 3 includes a column driving motor 30, and the column driving motor 30 is a servo motor. The column driving motor 30 can drive the steering column 2 to rotate a certain angle through a common mechanical transmission mechanism such as a worm gear mechanism. For example, the pipe column driving motor 30 drives the worm to rotate through the coupler, the worm wheel is sleeved on the steering pipe column 2, and the worm drives the worm wheel to rotate, so that the steering pipe column rotates by a certain angle. The lower rotation angle sensor 6 may be provided between the electromagnetic brake 4 transmission spline shaft 41 and the lower cover. The upper rotating angle sensor 5 and the lower rotating angle sensor 6 are respectively arranged above and below the disconnection position of the electromagnetic brake 4, after the electromagnetic brake 4 is disconnected, the controller 8 can continuously collect and track the rotating angle signals of the upper position and the lower position, and the steering column 2 driven by the control motor can drive the steering wheel 1 to rotate to the centering position.
In specific implementation, when the vehicle needs to turn to the land working condition, the switch 42 is turned on, the controller 8 controls the column driving motor 30 to drive the steering column 2 to drive the steering wheel 1 to rotate according to the rotation angle difference recorded by the upper and lower rotation angle sensors, and the rotation is stopped when the rotation angle difference is zero, so that the automatic steering centering is realized. Then, the controller adjusts the electromagnetic brake 4 to be in the normally engaged state. When the steering wheel 1 rotates, the steering transmission shaft 70 synchronously rotates to control the steering of the tires. When the steering wheel 1 rotates to the water working condition, the switch 42 is closed, the controller 8 controls the electromagnetic brake 4 to be separated, and the steering transmission shaft 70 does not turn any more when the steering wheel 1 rotates; at this time, the steering wheel 1 is turned, the upper turning angle sensor 5 generates a signal in accordance with the turning of the steering wheel 1, and the controller 8 controls the steering on the water.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
