Description

Technical Field

[0001] The utility model relates to the technical field of mechanical connection, in particular to a one-way clutch with a central motor for an electric vehicle. Background Art

[0002] With the rapid development of the electric vehicle industry, the performance requirements for electric vehicles are becoming increasingly higher. As an important component of the electric vehicle drive system, the performance of the mid-mounted motor directly affects the power output, driving speed, and stability of the electric vehicle. As a key component in the mid-mounted motor drive system, the one-way clutch's main function is to allow one-way power transmission during motor drive and prevent reverse transmission, thereby ensuring that the electric vehicle can accelerate and decelerate smoothly during driving. In electric vehicles, the mid-mounted motor transmits power to the rear wheels through a one-way clutch. The design of the one-way clutch needs to ensure efficient power transmission and reduce energy loss to improve the overall performance of the electric vehicle. The one-way clutch must be able to prevent reverse power transmission during braking or reversing, which helps improve the safety of the electric vehicle and prevent loss of control due to reverse slip.

[0003] In actual use, the one-way bearing is an important component in the clutch, responsible for transmitting one-way power. The lack of fastening components will cause the bearing to loosen easily during operation, affecting the structural stability of the entire clutch. Loose bearings will cause the internal clearance of the clutch to increase, thereby affecting the response speed and transmission efficiency of the clutch, resulting in unstable power transmission and affecting the smoothness of electric vehicle driving. Due to lack of fastening, the one-way bearing may be displaced during operation, increasing the friction between the bearing and adjacent components, resulting in increased bearing wear and shortening the service life of the clutch. Utility Model Content

[0004] The purpose of the utility model is to provide a one-way clutch for a mid-mounted motor of an electric vehicle. A fastening block is passed through the interior of a second positioning groove. This design can effectively fix the fastening block, thereby enhancing the stability of the entire clutch structure and reducing the loosening of components caused by vibration or impact. A second positioning hole is provided on the outer ring of the main body, and a threaded column is fixed to the inner ring of the second positioning hole through a threaded connection. This design makes the installation and disassembly process of the clutch more convenient. An inner hexagonal slot is provided at one end of the threaded column, which is convenient for using a wrench or other tools to quickly tighten or loosen.

[0005] To achieve the above object, a mid-motor one-way clutch for an electric vehicle is provided, comprising: a main body, a second positioning groove being defined at the top of the main body, a fastening block being passed through the interior of the second positioning groove, a second positioning hole being defined on the outer ring of the main body, a threaded post being threadedly connected to the inner ring of the second positioning hole, the threaded post passing through the outer ring of the fastening block, and a hexagonal socket being defined at one end of the threaded post;

[0006] The outer ring of the main body is fixedly connected to a reinforcing rib. The design of the second positioning hole penetrating the outer ring of the main body enhances structural stability, facilitates installation and removal, and improves connection strength and durability. The use of the reinforcing rib enhances the overall strength and torsional resistance of the clutch, reduces vibration, extends service life, and improves safety and adaptability.

[0007] In the described one-way clutch for a mid-motor electric vehicle, the inner ring of the fastening block abuts against a one-way bearing, the bottom end of the one-way bearing abuts against a circlip, and the circlip abuts against the top end of the inner ring of the main body. This structural design improves the wear resistance and reliability of the clutch, ensuring smooth operation.

[0008] According to the one-way clutch for a mid-mounted motor in an electric vehicle, the outer ring of the main body is provided with six first positioning grooves. The six positioning grooves improve the positioning accuracy and assembly efficiency of the clutch.

[0009] According to the one-way clutch for a mid-motor electric vehicle, a fixing block is fixedly connected to the outer ring of the main body, and first positioning holes are formed at both the upper and lower ends of the fixing block. The design of the fixing block enhances the fixation and supporting force of the clutch, ensuring stability during operation.

[0010] According to the one-way clutch for a mid-mounted motor in an electric vehicle, the number of the fixing blocks is six, and the fixing blocks cooperate with the reinforcing rib blocks and the first positioning holes. The design of the six fixing blocks makes the clutch structure more stable and improves the overall load-bearing capacity.

[0011] According to the one-way clutch for a mid-mounted motor in an electric vehicle, the inner ring of the fastening block cooperates with the one-way bearing, and the outer ring of the fastening block cooperates with the threaded column. This cooperation ensures precise matching and tight connection between the clutch components.

[0012] According to the one-way clutch for a mid-mounted motor in an electric vehicle, the threaded column and the second positioning hole cooperate with each other, and the threaded column and the hexagonal socket cooperate with each other. This cooperation design makes the installation and removal of the clutch more convenient and improves maintenance efficiency.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model is provided with a fastening block, a second positioning hole, a threaded column and a hexagonal inner groove, and the fastening block is passed through the inside of the second positioning groove. This design can effectively fix the fastening block, thereby enhancing the stability of the entire clutch structure and reducing the loosening of components caused by vibration or impact. The outer ring of the main body is provided with a second positioning hole, and the threaded column is fixed to the inner ring of the second positioning hole through a threaded connection. This design makes the installation and disassembly process of the clutch more convenient. One end of the threaded column is provided with a hexagonal inner groove, which is convenient for using tools such as wrenches to quickly tighten or loosen.

[0015] 2. The utility model is provided with reinforcing rib blocks, and the addition of the reinforcing rib blocks can significantly improve the outer ring strength of the main body, thereby enhancing the structural strength of the entire clutch, which is very important for bearing the torque output by the engine and various loads during vehicle operation. The design of the reinforcing rib blocks helps to disperse and resist the torque from the clutch, reducing component damage or fatigue cracks caused by excessive torque. The reinforcing rib blocks can absorb and disperse the vibrations generated by the operation of the engine, reduce the transmission of vibrations to other parts of the vehicle, improve ride comfort and reduce noise. Due to the presence of the reinforcing rib blocks, the clutch is more durable when bearing continuous working loads, thereby extending the service life of the clutch.
