Description

Technical Field

[0001] This utility model relates to the field of vehicle balancing machine technology, and in particular to a vehicle balancing machine drive device. Background Technology

[0002] A vehicle wheel balancer is a device used to detect and correct wheel imbalance, widely used in automotive repair and maintenance. Its main function is to detect and correct imbalances by rotating the wheels, thereby reducing vibrations during vehicle operation and improving driving safety and comfort. Traditional vehicle wheel balancers are typically manual, requiring operators to manually rotate the tires to perform the balance test.

[0003] However, the existing method of manually rotating tires has many drawbacks. First, the manual operation is cumbersome, requiring operators to accelerate the tire to a balanced speed, which is labor-intensive and inefficient. Second, manual rotation makes it difficult to ensure the uniformity and stability of the rotation speed, easily introducing human error and affecting the accuracy of the balance test. In addition, manual operation may also lead to operator fatigue, further reducing work efficiency and test quality. Utility Model Content

[0032] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to illustrate this utility model and are not intended to limit it.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0036] like Figures 1 to 4 The image shows one embodiment of the vehicle-mounted balancing machine drive device of this utility model.

[0037] See Figure 1 and Figure 2 The vehicle-mounted balancing machine drive device of this embodiment includes a drive motor 1 and a transmission assembly 2. The output shaft of the drive motor 1 is selectively connected to or separated from the transmission assembly 2 through a separable connection structure 3. The transmission assembly 2 is also connected to the main shaft 4 of the vehicle-mounted balancing machine. The output shaft of the drive motor 1 drives the main shaft 4 to rotate through the transmission assembly 2.

[0038] The drive motor 1 serves as the power source, providing rotational power through the output axial transmission assembly 2. Upon receiving the rotational power from the drive motor 1, the transmission assembly 2 synchronously drives the main shaft 4 of the vehicle balancing machine to rotate. The detachable connection structure 3 is used to selectively connect or disconnect the drive motor 1 and the transmission assembly 2. The main shaft 4 is the rotating component of the vehicle balancing machine, used to mount tires for balance testing.

[0039] In the connected state, the output shaft of the drive motor 1 is connected to the transmission assembly 2 via the detachable connection structure 3. Power is transmitted from the drive motor 1 to the transmission assembly 2, and then to the main shaft 4, driving the main shaft 4 to rotate. The drive motor 1 provides rotational power to the main shaft 4 of the vehicle-mounted balancing machine through the detachable connection structure 3 and the transmission assembly 2, enabling the tires mounted on the main shaft 4 to accelerate to the required balancing speed.

[0040] In the disassembled state, the separable connection structure 3 is disconnected, the power of the drive motor 1 cannot be transmitted to the transmission component 2, the transmission component 2 is disengaged from the drive motor 1, and the main shaft 4 can rotate freely. After the tire mounted on the main shaft 4 reaches the equilibrium speed, the transmission component 2 is separated from the drive motor 1 by the separable connection structure 3, which can avoid the influence of the vibration of the drive motor 1 on the balance measurement accuracy and ensure the accuracy of the measurement results.

[0041] Therefore, in this embodiment, the vehicle-mounted balancing machine drive device provides power through the drive motor 1, which is transmitted to the transmission assembly 2 via the detachable connection structure 3, thereby driving the main shaft 4 to rotate and accelerating the tires to the balancing speed. Then, the power transmission is cut off through the detachable connection structure 3, allowing the main shaft 4 to rotate freely, thus avoiding motor vibration interference and ensuring measurement accuracy. The drive motor 1 replaces manual rotation, significantly reducing the operator's workload and improving operational efficiency.

[0042] See Figure 1 and Figure 2Preferably, the detachable connection structure 3 includes an electromagnetic clutch 31. The input end of the electromagnetic clutch 31 is connected to the output shaft of the drive motor 1, and the output end of the electromagnetic clutch 31 is connected to the transmission assembly 2. The on / off control method of the electromagnetic clutch 31 is simple and efficient: when the electromagnetic clutch 31 is energized, it stably transmits the power of the drive motor 1 to the transmission assembly 2, thereby driving the main shaft 4 to rotate, enabling the tire to accelerate to the required balance speed, and ensuring the uniformity and stability of the rotation speed, thus improving the reliability of the balance detection; when the electromagnetic clutch 31 is de-energized, it disconnects the drive motor 1 from the transmission assembly 2, avoiding interference from motor vibration on the balance measurement, and ensuring high accuracy of the measurement results. Furthermore, the electromagnetic clutch 31 is electrically connected to the control unit of the vehicle-mounted balancer. The control unit controls the on / off of the electromagnetic clutch 31 according to whether the tire installed on the main shaft 4 has reached the balance speed, thereby realizing automated control of the on / off of the electromagnetic clutch 31, improving the automation level and operational convenience of the vehicle-mounted balancer drive device.

[0043] See Figure 1 and Figure 2 Preferably, the detachable connection structure 3 further includes an armature bracket 32, which is fixedly connected to the armature of the transmission assembly 2 and the electromagnetic clutch 31, respectively. The armature bracket 32 ​​serves to support and transmit power. The electromagnetic clutch 31 contains components such as a coil, an armature, and a return spring. The armature is used to contact the output end of the electromagnetic clutch to transmit power or to disengage to break the power transmission.

[0044] When the electromagnetic clutch 31 is energized, the coil generates a magnetic field, which attracts the armature and tightly engages it with the output end of the electromagnetic clutch 31. When the drive motor 1 starts, the generated power is first transmitted to the input end of the electromagnetic clutch 31 through the output shaft of the drive motor 1, and then output through the output end of the electromagnetic clutch 31 to drive the armature to rotate. Since the armature bracket 32 ​​is fixedly connected to the transmission assembly 2 and the armature of the electromagnetic clutch 31, the rotation of the armature drives the transmission assembly 2 to rotate through the armature bracket 32. Finally, the power is transmitted from the transmission assembly 2 to the main shaft 4 of the vehicle balancing machine, causing the main shaft 4 to rotate.

[0045] When the electromagnetic clutch 31 is de-energized, the magnetic field generated by the coil disappears, and the return spring pulls the armature back to its original position, separating the armature from the output end of the electromagnetic clutch 31. At this time, the power received by the drive motor 1 from the electromagnetic clutch 31 cannot be transmitted to the armature through the output end of the electromagnetic clutch 31. Therefore, the transmission assembly 2, which is fixedly connected to the armature through the armature bracket 32, also cannot receive power. This allows the main shaft 4 of the vehicle-mounted balancing machine to rotate freely, avoiding interference from motor vibration on the balance measurement.

[0046] See Figure 1 and Figure 2 Preferably, the vehicle-mounted balancing machine drive device of this embodiment further includes a first mounting plate 5, a second mounting plate 6, and a mounting link 7. The drive motor 1 is mounted on the first mounting plate 5, and the transmission assembly 2 is mounted on the second mounting plate 6. The two ends of the mounting link 7 are respectively connected to the first mounting plate 5 and the second mounting plate 6. The first mounting plate 5 and the second mounting plate 6 provide stable mounting platforms for the drive motor 1 and the transmission assembly 2, ensuring that the drive motor 1 and the transmission assembly 2 will not shift or shake during operation, thus maintaining a stable position. The connecting function of the mounting link 7 makes the relative position between the drive motor 1 and the transmission assembly 2 more fixed, thereby ensuring that power can be smoothly and efficiently transmitted from the drive motor 1 to the transmission assembly 2. By connecting the first mounting plate 5 and the second mounting plate 6 together through the mounting link 7, the drive motor 1 and the transmission assembly 2 are fixed in an integral structure, thereby ensuring the structural stability of the vehicle-mounted balancing machine drive device of this embodiment when transmitting power.

[0047] See Figure 1 and Figure 2 Preferably, both ends of the mounting rod 7 are detachably connected to the first mounting plate 5 and the second mounting plate 6 via bolts. This detachability of the bolted connection facilitates the installation and maintenance of the drive motor 1 and the transmission assembly 2. When maintenance, replacement, or adjustment of the drive motor 1 and the transmission assembly 2 is required, the mounting rod 7 can be quickly disassembled by loosening the bolts, thereby easily separating the first mounting plate 5 and the second mounting plate 6. After maintenance, the bolts are tightened to reconnect the components, ensuring the stability of the vehicle-mounted balancing machine drive device.

[0048] See Figure 1 and Figure 2 Preferably, multiple mounting rods 7 are provided, and the multiple mounting rods 7 are respectively connected to the edge areas of the first mounting plate 5 and the second mounting plate 6. By connecting the multiple mounting rods 7 to the edge areas of the first mounting plate 5 and the second mounting plate 6 respectively, a stable frame structure is formed, which further improves the stability of the vehicle-mounted balancing machine drive device of this embodiment.

[0049] In this embodiment, preferably, the drive motor 1 is a DC geared motor. A DC geared motor can output stable low-speed, high-torque power, ensuring that the tires can smoothly accelerate to the required balance speed, while reducing vibration and impact during power transmission, making it suitable for the use of vehicle-mounted balancing machines.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
