Description

Technical Field

[0001] This utility model relates to the field of new energy motor technology, specifically to a dual-axis motor. Background Technology

[0002] As new energy electric vehicles continue to develop, the requirements for steering motors in the vehicle steering control system are becoming increasingly stringent. Current motors mainly suffer from the following problems: 1. One motor can only be used in one operating mode; 2. An oil pump is installed on the front cover to help the motor work, and a high-voltage connector and grounding wire are installed on the rear cover, which is generally used in traditional new energy buses; 3. The motor output shaft is connected by a block; 4. The wiring harness connector has poor contact. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a dual-axis motor with a simple structure, which can be used in two working modes and has a longer service life.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A dual-shaft motor includes a housing, a front cover, and a rear cover. The front cover and rear cover are mounted on the right and left ends of the housing, respectively. A junction box is mounted on the top of the housing. A motor shaft is installed inside the housing. Spline connection holes are distributed on both the left and right ends of the motor shaft. An insulating shock-absorbing pad is also installed on the bottom of the housing by fixing bolts. A terminal block and a motor lead wire are fixed inside the junction box by fastening bolts. A nut and a vent valve are also fixed on the side of the junction box.

[0006] A further technical solution is that the front cover and the rear cover are also provided with mounting holes, and the inner walls of the mounting holes are provided with threads for installation with other components. Bolts can be used for fixing, and of course, other threaded connectors can also be used.

[0007] A further technical solution is that the nut is a shielded waterproof nut, which has a waterproof effect and improves the service life of the internal motor lead wire. The shielded waterproof nut adopts a special structural design and is made of materials with good waterproof performance. It can effectively prevent moisture, dust, sand and other debris from entering and protect the equipment or structure from water corrosion. In addition, the shielded waterproof nut also has the characteristics of shock resistance and anti-loosening. It can resist the influence of vibration and shock, prevent the nut from loosening and falling off, and ensure the safety of the equipment or structure.

[0008] A further technical solution is that a grounding wire is also connected to the front cover, and the grounding wire of the motor is located on the edge of the front cover on the right side of the housing, which facilitates grounding at different locations and improves vehicle loading efficiency.

[0009] The beneficial effects of this utility model are:

[0010] This utility model discloses a dual-shaft motor. The original connecting block on the motor shaft is eliminated, and a spline connecting hole is distributed at both ends for connection. It can install two oil pumps to work together and use two operating modes. The original bent feet on the motor housing are eliminated. The design adopts a design where the bottom of the housing is drilled and fixed with bolts to install insulating and shock-absorbing pads, which saves costs. At the same time, the addition of a junction box and terminal block solves the problem of poor contact of the motor connector and extends the service life of the entire motor.

Detailed Implementation

[0015] The preferred embodiments of this utility model will be described in detail below so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of this utility model.

[0016] See Figure 1 and Figure 2 As shown, a dual-shaft motor includes a housing 15, a front cover 3, and a rear cover 2. The front cover 3 and the rear cover 2 are installed on the right and left ends of the housing 15, respectively. A junction box 1 is installed on the top of the housing 15. A motor shaft 7 is installed inside the housing 15. Spline connection holes 5 are distributed on both the left and right ends of the motor shaft 7. An insulating shock-absorbing pad 8 is also installed at the bottom of the housing 15 by fixing bolts 16. A terminal block 12 and a motor lead wire 13 are fixed inside the junction box 1 by fastening bolts 11. A nut 14 and a vent valve 9 are also fixed on the side of the junction box 1.

[0017] Mounting holes 4 are distributed on the front cover 3 and the rear cover 2. The inner wall of the mounting holes 4 is threaded for installation with other components. Bolts can be used for fixing, and other threaded connectors can also be used. Nut 14 is a shielded waterproof nut, which provides a waterproof effect and improves the service life of the internal motor lead wire 13. The shielded waterproof nut adopts a special structural design and is made of materials with good waterproof performance. It can effectively prevent moisture, dust, sand and other debris from entering, protecting the equipment or structure from water corrosion. In addition, the shielded waterproof nut also has the characteristics of shock resistance and anti-loosening. It can resist the effects of vibration and shock, prevent the nut from loosening and falling off, and ensure the safety of the equipment or structure. The front cover 3 is also connected to a grounding wire 6. The motor grounding wire 6 is located on the right side of the front cover 3 of the housing 15, which facilitates grounding at different locations and improves loading efficiency.

[0018] In this embodiment, the motor shaft 7 is connected by splined connection holes 5 distributed at both ends, which can be used to install two oil pumps to work together. The rotation direction is also changed from the original single rotation direction to double rotation direction. The motor housing adopts a design where the bottom of the housing 15 is drilled and the insulating shock-absorbing pad 8 is installed by fixing bolts 16, which saves costs. A junction box 1 and a terminal block 12 are also added. Through the nut 14 and the vent valve 9 on the junction box 1, it can be effectively isolated from water, solve the problem of poor contact, and extend the service life. An OT terminal 10 is also placed on the terminal block 12. The OT terminal 10 and the end of the motor lead wire 13 are locked together by the fastening bolt 11. The electrical connection wire inside the housing 15 passes through the housing 15 and the junction box 1 and then connects to the OT terminal 10.

[0019] Among them, the vent valve 9 has a specific function of waterproofing and ventilating, while the motor lead wire 13 passes through the shielded waterproof nut and connects to the external electrical components.

[0020] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that are conceived without creative effort should be covered by the protection scope of this utility model.
