Description

Technical Field

[0001] The present invention belongs to the technical field of smart electric vehicles, and in particular relates to a torsion support structure of a front fork part of a front-wheel drive smart electric vehicle. Background Art

[0002] Usually, the front fork of an electric vehicle includes two fork parts on the left and right, and the fork parts are provided with forks in a flat shape. When the front wheel motor is driven, the flat square parts at both ends of the motor shaft are installed in the forks, and then the two ends are locked by nuts. When the motor outputs torque, the motor shaft generates torque on the fork part, and the torque acts on the shock absorber on the front fork, thereby achieving a shock absorption effect.

[0003] Since the front fork of an electric vehicle is driven by a front wheel motor, it will bear a greater torque, which may easily cause the fork opening of the front fork to deform or be damaged. After the fork opening of the front fork is deformed or damaged, the front wheel motor may fall off easily, causing a safety accident. Currently, the front fork on the market does not have a front wheel torque support structure, or the front wheel torque support structure is complex to install, the production cost is high, and the production quality is difficult to control. In view of the above problems, the applicant has proposed a torque support structure with simple and reliable structure, convenient production and installation, and controllable production quality. Summary of the invention

[0004] In view of the above deficiencies in the prior art, the purpose of the present invention is to provide a torque support structure with simple and reliable structure, convenient production and installation, and controllable production quality, so as to share the motor torque, avoid damage to the front fork fork, and prevent the front wheel motor from falling off.

[0005] To achieve the above object, the technical solution of the present invention is:

[0006] A torsion support structure of an intelligent electric vehicle comprises a front fork, wherein the end of the front fork is provided with two left and right fork openings, the fork openings are provided with a fork, the inner side and / or the outer side of the fork openings are provided with a torque support gasket groove, a corresponding torque support gasket is provided in the torque support gasket groove, the torque support gasket is an eccentric structure or an arbitrary non-rotating structure, and the strength of the torque support gasket is greater than the strength of the fork opening; the torque support gasket is provided with a closed flat square hole or an open flat square groove, and the flat square part of the motor shaft cooperates with the closed flat square hole or the open flat square groove.

[0007] The present invention adds a torque supporting gasket on the side of the front fork fork opening, and the flat square part of the motor shaft is installed in the flat square hole or flat square groove of the front fork fork opening and the torque supporting gasket, so as to share the torque of the motor shaft. At the same time, since the torque supporting gasket has higher strength, the damage to the front fork fork opening can be greatly reduced, and the front wheel motor can be prevented from falling off after the front fork fork opening is deformed, thereby improving the safety performance of the electric vehicle. In addition, from a structural point of view, the present invention only adds a gasket groove on the side of the front fork fork opening, and installs the torque supporting gasket in the gasket groove. The structure is simple and reliable, the production and installation are convenient, and the production quality is also controllable.

[0008] Furthermore, the inner and outer sides of the fork opening are respectively provided with an inner torsion support gasket groove and an outer torsion support gasket groove, the inner torsion support gasket is provided in the inner torsion support gasket groove, and the outer torsion support gasket is provided in the outer torsion support gasket groove. Since the torque support gaskets are provided on both the inner and outer sides of the front fork fork opening, the torque of the motor shaft can be better shared and the front fork fork opening can be better protected.

[0009] Furthermore, the outer torsion support gasket and the inner torsion support gasket are eccentric structures, a closed flat square hole is provided in the middle of the large end circular part of the outer torsion support gasket, and an open flat square groove is provided in the large end circular part of the inner torsion support gasket. Since the outer torsion support gasket adopts a closed flat square hole and the inner torsion support gasket adopts an open flat square groove, during installation, the inner torsion support gasket is first installed in the gasket groove on the inside, and then the motor shaft is inserted into the flat square groove of the inner torsion support gasket, and then the outer torsion support gasket is installed in the gasket groove on the outside, so that the motor shaft passes through the flat square hole of the outer torsion support gasket, and finally locked by the nuts on both sides, the installation of the front wheel can be completed. In addition to being convenient for inserting the motor shaft into the front fork structure, it is also better prevented from falling off the front wheel motor due to the restriction of the closed flat square hole.

[0010] Furthermore, the fork opening is made of aluminum alloy, and the torsion support gasket is made of stainless steel. Since the fork opening is made of high-strength aluminum alloy, the weight can be reduced. Meanwhile, the torsion support gasket is made of stainless steel, which has higher strength than aluminum alloy and lower material cost than other materials (such as titanium alloy).

[0011] Furthermore, the torsion support gasket is fixed to the torsion support gasket groove by bolt connection, riveting or welding. Since the torsion support gasket is fixed to the gasket groove by bolt connection, riveting or welding, the torsion support gasket can be better prevented from rotating after being stressed.

[0012] Further, the fork piece is provided with a front fender bracket mounting hole. During installation, the lower end of the front fender bracket is locked on the fork piece by bolts and nuts.

[0013] Furthermore, the fork piece is provided with a wire clip for fixing the motor wire. During installation, the front wheel motor wire is fixed in the wire clip.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Share the torque of the front wheel motor, reduce the damage to the front fork fork, prevent the front wheel motor from falling off, and improve the safety of the smart electric vehicle.

[0027] The present invention adds a torque supporting gasket on the side of the front fork fork opening, and the flat square part of the motor shaft is installed in the flat square hole or flat square groove of the front fork fork opening and the torque supporting gasket, so as to share the torque of the motor shaft. At the same time, since the torque supporting gasket has higher strength, the damage of the front fork fork opening can be greatly reduced, and the front wheel motor can be prevented from falling off after the front fork fork opening is deformed, thereby improving the safety performance of the electric vehicle. In addition, from a structural point of view, the present invention only adds a gasket groove on the side of the front fork fork opening, and installs the torque supporting gasket in the gasket groove.
