Description

Technical Field

[0001] This utility model relates to the field of drive motor technology, and in particular to a wheel drive motor for a steering wheel of a walking machine. Background Technology

[0002] Traditional wheel-driven hydraulic motors consist of a standard wheel-type hydraulic motor and a steering pivot bracket, forming the steering wheel structure of the mobile machinery. In this structure, the hydraulic port is located on the motor housing. After installation, the hydraulic oil pipe swings with the steering of the wheel, which takes up a lot of space and is very inconvenient to protect. As the hydraulic oil pipe swings and twists, it is very easy to be damaged. At the same time, complex mechanical devices are required to install the motor on the frame, which increases the manufacturer's costs and makes maintenance very inconvenient.

[0003] For agricultural machinery vehicles that frequently operate in the fields, traditional wheel-driven hydraulic motors are no longer sufficient. Traditional hydraulic motors have their oil inlets located on the motor housing; after installation, the hydraulic hoses swing with the steering of the wheels, taking up considerable space and making protection very inconvenient. Furthermore, the hydraulic hoses are easily damaged due to the swinging and twisting of the hoses. Installation requires complex mechanical devices to mount the motor on the frame, occupying significant space inside the steering wheels. Therefore, we propose a wheel-driven motor for the steering wheels of mobile machinery. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] refer to Figure 1-4 A wheel drive motor for a steering wheel of a traveling machine includes a C-shaped bracket 3. A rotating pin 9 is rotatably mounted on the inner side of the C-shaped bracket 3, and a rotary joint assembly 4 is fixedly mounted on the outer side of the rotating pin 9. A main housing 2 is fixedly mounted on the outer side of the rotary joint assembly 4. An output flange shaft 1 is provided on the inner side of the rotary joint assembly 4, and a rotor assembly 5 is provided on the output flange shaft 1. The rotary joint assembly 4 ensures that the hydraulic oil port opens at the top of the steering pivot, preventing it from swinging with the steering of the wheel, thus avoiding some weaknesses of rubber hoses and improving the reliability of the system. The C-shaped bracket 3 uses a special steering pivot structure to replace the traditional bogie, significantly saving space inside the steering wheel, while also having an excellent rotation angle, which can reduce the turning radius of the vehicle, providing agricultural machinery manufacturers with a brand-new design concept. The output flange shaft 1 has a hub output structure, which is more convenient for connecting to the tire. In this embodiment, a support housing 6 is fixedly mounted on the outer side of the rotary joint assembly 4, and a curved raceway 7 is bolted onto the support housing 6.

[0025] In this embodiment, an oil distributor 8 is fixedly installed inside the main housing 2, and the main housing 2 is rotatably connected to the rotating pin 9; a speed sensor 11 can be installed on the support housing 6 to monitor the vehicle speed in real time, so as to complete agricultural operations more effectively and with higher quality; an angle sensor 12 can be installed at the position of the rotating pin 9 to monitor the steering state of the steering wheel in real time, so as to better control the vehicle turning and walking; in this embodiment, bearing assemblies 10 are provided on the left and right sides of the outer side of the output flange shaft 1, and a speed sensor 11 is provided on the top of the support housing 6; in this embodiment, an angle sensor 12 is provided on the top of the rotating pin 9, and the angle sensor 12 and the speed sensor 11 are electrically connected.

In this embodiment, the upper part of the rotor assembly 5 is provided with an internal spline, which is connected to the external spline of the output flange shaft 1.

The oil is then distributed into the rotor assembly 5 by the oil distributor 8 installed inside the main housing 2. The oil pushes the piston inside the rotor assembly 5 to roll on the curved raceway 7. When the curved raceway 7 is stationary, the reaction force pushes the rotor assembly 5 to rotate in the opposite direction. The rotor assembly 5 drives the output flange shaft 1 to rotate through the internal spline connection, thereby realizing the power output; the frame is connected to the C-type bracket 3, and the steering cylinder is connected to the main housing 2 through mechanical parts. When the vehicle needs to turn, the steering cylinder pushes the main housing 2 to rotate, thereby realizing the vehicle steering. At this time, the pipeline connected to the steering joint rotary joint assembly 4 will not rotate with the rotation of the main housing 2, but will always remain parallel to the C-type bracket 3, which improves the reliability of the pipeline connection; in this embodiment, a connecting flange is provided at the connection between the rotating pin 9 and the C-type bracket 3, and the connecting flange bolts are installed on the C-type bracket 3.

[0027] The implementation principle of a wheel drive motor for a steering wheel of a traveling machine in this embodiment is as follows: The wheel drive hydraulic motor for the steering wheel of a traveling machine consists of an output flange shaft 1, a main housing 2, a C-type bracket 3, a rotary joint assembly 4, a rotor assembly 5, a support housing 6, a curved raceway 7, a distributor 8, a rotating pin 9, a support bearing assembly 10, and seals, etc.; the output flange shaft 1 passes through the bearing assembly 10, the main housing 2, the distributor 8, the rotor assembly 5, and the bearing assembly 10. The distributor 8 is installed inside the main housing 2. The C-type bracket 3 is connected to the main housing 2 through the rotary joint assembly 4 and the rotating pin 9. The support housing 6 is connected to the main housing 2 by screws passing through the curved raceway 7. The bearing assembly 10 is installed in the main housing 2 and the support housing 6. The bearing assembly 10 is fixedly connected to the output flange shaft 1. The rotor assembly 5 is connected to the output flange shaft 1 through a spline to achieve torque output;

[0028] The rotary joint assembly 4 enables the hydraulic port to open at the top of the steering pivot, preventing it from swinging with the steering of the wheel, thus avoiding some weaknesses of the hose and improving the reliability of the system.

[0029] The C-type bracket 3 uses a special steering pivot structure to replace the traditional bogie, which significantly saves space inside the steering wheel and has an excellent rotation angle, which can reduce the turning radius of the vehicle and provide agricultural machinery manufacturers with a brand-new design concept; the output flange shaft 1 has a hub output structure, which makes it easier to connect to the tire;

[0030] A speed sensor 11 can be installed on the support housing 6 to monitor the vehicle speed in real time, enabling agricultural operations to be completed more effectively and with higher quality.

[0031] An angle sensor 12 can be installed at the position of the rotating pin 9 to monitor the steering status of the steering wheel in real time, thereby better controlling the vehicle's turning and movement;

[0032] During operation, the oil enters from the upper port of the rotary joint assembly 4, passes through the rotary joint and rotary joint assembly 4 into the main housing 2, and is then distributed into the rotor assembly 5 by the oil distributor 8 installed inside the main housing 2. The oil pushes the piston inside the rotor assembly 5 to roll on the curved raceway 7. When the curved raceway 7 is stationary, the reaction force pushes the rotor assembly 5 to rotate in the opposite direction. The rotor assembly 5 drives the output flange shaft 1 to rotate through the internal spline connection, thereby realizing the output of power. The frame is connected to the C-type bracket 3, and the steering cylinder is connected to the main housing 2 through mechanical parts. When the vehicle needs to turn, the steering cylinder pushes the main housing 2 to rotate, thereby realizing the vehicle steering. At this time, the pipeline connected to the rotary joint assembly 4 of the steering joint does not rotate with the rotation of the main housing 2, but always remains parallel to the C-type bracket 3, which improves the reliability of the pipeline connection.

[0033] During operation, the speed sensor 11 installed on the support housing 6 monitors the rotation speed of the motor in real time, thereby determining the vehicle's travel speed and completing the task more effectively and with higher quality; the angle sensor 12 installed on the rotating pin 9 monitors the rotation angle of the motor in real time, thereby determining the vehicle's motion status and better controlling the vehicle.
