The utility model adopts the following technical scheme:

the utility model provides a triaxial car all-wheel steering system, includes primary shaft, secondary shaft and third axle, primary shaft, secondary shaft and third axle all include two wheels, two steering linkage and a steering mechanism, every steering linkage's one end is connected steering mechanism, the other end is connected one the wheel, the epaxial steering mechanism of primary shaft and steering wheel mechanical connection, the epaxial steering mechanism electric connection of secondary shaft and third has the initiative steering control ware, initiative steering control ware and vehicle control unit communication connection, primary shaft, secondary shaft and third axle have two wheels of an axle at least to set actuating mechanism.

In a first preferred aspect, a drive mechanism is provided for each of the two wheels of any one of the first shaft, the second shaft, and the third shaft.

In a second preferred aspect, all the wheels of any two of the first shaft, the second shaft, and the third shaft are provided with the driving mechanism.

In a third preferred aspect, all the wheels on the first shaft, the second shaft and the third shaft are provided with the driving mechanism.

Specifically, the driving mechanism comprises a driving motor and a transmission, wherein the output end of the driving motor is mechanically connected with the wheels through the transmission, the driving motor is electrically connected to a motor controller, and the motor controller is in communication connection with the vehicle control unit.

Furthermore, the transmission comprises one or more combinations of the speed change mechanism and the speed reduction mechanism, and the optimal matching of the whole vehicle dynamic property and the economy can be better realized through the reasonable matching of the speed change mechanism and the speed reduction mechanism.

It can be seen from the above description that the structure of the present invention is more advantageous than the prior art:

the utility model discloses a three axletree all has the function of turning to, can realize that the whole round turns to, can reduce turning radius, effectively improves whole car trafficability characteristic. The utility model is a distributed driving system configuration, which can solve the problem that the central direct drive can not realize the low floor arrangement; through the flexible matching of the three axle driving mechanisms, the requirements of different customers can be met, the three-axle driving mechanism is suitable for various road conditions, and the overall vehicle operation stability is effectively improved.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings. Numerous details are set forth in the following description in order to provide a thorough understanding of the present invention, but it will be apparent to one skilled in the art that the present invention may be practiced without these details. Well-known components, methods and processes are not described in detail below.

The utility model provides a triaxial car all-wheel steering system, refer to fig. 1, including primary shaft 10, secondary shaft 20 and third axle 30. The first, second and

third axles

10, 20, 30 each comprise two wheels 11, a steering mechanism 12 and two steering rods 13. Each tie rod 13 is connected at one end to a steering mechanism 12 and at the other end to one wheel 11. The steering mechanism 12 on the first shaft 10 is mechanically connected with the steering wheel 1, the steering mechanisms 12 on the second shaft 20 and the third shaft 30 are electrically connected with an active steering controller 14, the active steering controller 14 is in communication connection with the vehicle control unit 2, and two wheels of at least one shaft of the first shaft 10, the second shaft 20 and the third shaft 30 are provided with driving mechanisms.

As shown in fig. 1, all the wheels 11 of the second shaft 20 and the third shaft 30 are provided with the driving mechanism, but it is needless to say that the four wheels 11 of the first shaft 10 and the second shaft 20 may be provided with the driving mechanism, or the four wheels 11 of the first shaft 10 and the third shaft 30 may be provided with the driving mechanism.

As shown in fig. 2, a drive mechanism is provided to the two wheels 11 of the second shaft 20. Of course, it is also possible that both wheels 11 of the first shaft 10 are provided with a drive mechanism, or that both wheels 11 of the third shaft 30 are provided with a drive mechanism.

As shown in fig. 3, all the wheels 11 on the first shaft 10, the second shaft 20 and the third shaft 30 are provided with the driving mechanism.

Referring to fig. 1, the driving mechanism includes a driving motor 41 and a transmission 42, an output end of the driving motor 41 is mechanically connected with the wheel 11 through the transmission, the driving motor 41 is electrically connected to a motor controller 411, and the motor controller 411 is in communication connection with the vehicle control unit 2.

The transmission 42 comprises one or more combinations of a speed change mechanism and a speed reduction mechanism, and the optimal matching of the vehicle dynamic property and the economy can be better realized through the reasonable matching of the speed change mechanism and the speed reduction mechanism.

The three-axle automobile all-wheel steering system comprises three turning modes, namely an entire automobile translation mode, an all-wheel turning mode and a front wheel turning mode. Referring to fig. 4, in the whole vehicle translation mode, all the steering wheels face in the same direction, so that the vehicle can conveniently realize the side parking function, and the vehicle parking station is facilitated. Referring to fig. 5, in the all-wheel turning mode, all the wheels 11 are turned and the turning centers meet at a point, and the turning radius is small, that is, the turning sensitivity is high, so that the trafficability of the vehicle running at a low speed is improved. Referring to fig. 6, in the front wheel turning mode, only the front axle wheels are turned, and the rear axle wheels keep running straight, the turning radius is larger, i.e. the turning sensitivity is lower, and the safety of high-speed running is improved.

The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
