Embodiment 1

[0032] see figure 2 , an electric steering system for new energy vehicles, including the electric steering system body 1 in the prior art, and also includes a damping assembly that cooperates with the electric steering system body 1, the steering of the electric steering system body 1 A damping steel disc 2 is installed on the input shaft 12; the damping steel disc 2 is a circular structure supported by steel.

[0033] It should be specifically noted that the damping assembly includes a first damping block 3 and a second damping block 4, the first damping block 3 and the second damping block 4 can independently form a magnetic field, and the first damping block 3 and the second damping block 4 can independently form a magnetic field. There is a gap between the second damping block 4, which is used to place the damping steel plate 2, and the magnetic poles of the first damping block 3 and the end of the second damping block 4 that are close to each other are different; A magn...

Embodiment 2

[0037] This embodiment is a further limitation of embodiment 1 on the basis of embodiment 1, specifically refer to figure 2 and Figure 8 , in this embodiment, also includes a power supply unit 5, the power supply unit 5 is a DC power supply 51, the first damping block 3 and the second damping block 4 are made of non-ferromagnetic materials; wherein, the first damping block 3 is wound with a first wire harness 31, the two ends of the first wire harness 31 are respectively electrically connected with the positive and negative poles of the power supply unit 5, the second damping block 4 is wound with a second wire harness 41, the Two ends of the second wire harness 41 are respectively electrically connected to the positive and negative poles of the power supply unit 5 .

[0038] It should be specifically noted that one end of the first wiring harness 31 is connected in parallel with one end of the second wiring harness 41 through the first bus 32 and is electrically connected ...

Embodiment 3

[0042] This embodiment is an alternative to embodiment 2, for specific reference image 3 , the first damping block 3 and the second damping block 4 are made of ferromagnetic materials.

[0043] The difference with Embodiment 2 is that the magnetic field provided by Embodiment 2 to the damping steel plate 2 is realized by electric energy. In this embodiment, the magnetic field used to supply the damping steel plate 2 is realized by a permanent magnet. Other structures of this embodiment It is the same as that in Embodiment 2 and will not be repeated here.

Abstract

The invention relates to the technical field of automobile steering, and discloses an electric steering system for a new energy automobile. The electric steering system comprises an electric steering system body and further comprises a damping assembly matching the electric steering system body to work, and a damping steel disc is mounted on a steering input shaft of the electric steering system body; the damping assembly comprises a first damping block and a second damping block, the first damping block and the second damping block can independently form a magnetic field, a gap exists between the first damping block and the second damping block, and the gap is used for containing the damping steel disc. According to the electric steering system for the new energy automobile, when people violently rotate a steering wheel, the rotation of the steering wheel can be damped, and therefore the problems that the automobile body is unstable in advancing and seriously deviates from a roadway due to the fact that the steering wheel is violently turned in the advancing process of the automobile are solved.

Description

technical field [0001] The invention relates to the technical field of automobile steering, in particular to an electric steering system for new energy automobiles. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources to drive vehicles. The unconventional vehicle fuels here refer to fuels other than gasoline and diesel. The most common new energy vehicles on the market are mostly powered by electricity. As a vehicle with driving energy, most of the steering systems of existing new energy vehicles are electric power steering systems. [0003] In the existing electric power steering system, based on the traditional mechanical steering system, a steering sensor is installed at the steering input shaft, and the steering sensor controls the power-assisted motor to drive the steering input shaft according to the direction information of the steering input shaft, so as to achieve labor-saving As a result, the steering ...
