Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of logging equipment, and particularly relates to a wave wheel direction device for a forest logging vehicle. Background Technique
[0002] A forest logging vehicle is a device for carrying out logging operations in the wild forest land, with a logging operation direction and a vehicle driving direction. The driver can select logging operations or drive the vehicle by rotating the orientation of the seat. The traditional steering wheel is fixed in the direction of the vehicle's forward movement in the cab, and is transmitted to the steering gear or hydraulic steering gear through mechanical transmission, so as to drive the vehicle to turn. However, after the seat rotates, the steering wheel cannot be operated to control the vehicle to move or carry out logging operations, which is inconvenient to use. Installing steering wheels at both ends of the cab will occupy the space in the cab, and the control mechanism is complex. Content of the Utility Model
[0003] The purpose of the utility model is to provide a wave wheel direction device for a forest logging vehicle to solve the technical problems raised in the above background technique.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A wave wheel direction device for a forest logging vehicle includes a steering wheel housing, an aviation joint, an encoder, an encoder fixing seat, a bearing seat, a wave wheel fixing shaft, and a steering wheel wave wheel. The steering wheel housing is vertically arranged, with a hollow interior, and an installation hole penetrating the interior is provided on the left lower side wall; the encoder is vertically arranged, and its housing is fixedly arranged in the steering wheel housing through the encoder fixing seat; the bearing seat is fixedly arranged in the upper part of the steering wheel housing at the lower part; the wave wheel fixing shaft is rotatably arranged in the bearing seat, its lower part is connected to the rotating shaft of the encoder, and the upper part extends out of the top surface of the bearing seat; the middle part of the steering wheel wave wheel is fixedly connected to the top surface of the wave wheel fixing shaft; the aviation joint is horizontally arranged in the installation hole of the steering wheel housing and is connected to the encoder.
[0006] Further, the wave wheel fixing shaft is rotatably arranged in the bearing seat through a bearing.
[0007] Further, two bearings are provided.
[0008] Further, the wave wheel fixing shaft is connected to the rotating shaft of the encoder through a coupling.
[0009] Further, a connection hole is provided on the right side wall of the steering wheel housing; an encoder indicator light is also included; the encoder indicator light is arranged in the connection hole and is connected to the encoder.
[0010] Furthermore, it further includes a spring and a friction member; a slot is provided at the top of the bearing seat; the spring is vertically arranged in the slot, and its bottom end is fixedly connected to the inner bottom of the slot; the friction member is vertically arranged, its bottom surface is fixedly connected to the top surface of the spring, and its top surface is in contact with the fixed shaft of the wave wheel.
[0011] Furthermore, there are two said slots, which are respectively circumferentially spaced and opened on the top surface of the bearing seat; there are two said springs and friction members corresponding to the slots respectively.
[0012] When the driver rotates the steering wheel wave wheel, it drives the fixed shaft of the wave wheel to rotate. The fixed shaft of the wave wheel drives the rotating shaft of the encoder through a coupling. The encoder converts the rotation into an electronic signal, and reads the electronic signal of the encoder through an aviation connector and outputs it to the control system. The control system can then make corresponding controls on the steering mechanism of the logging vehicle according to the electronic signal. After the driver stops rotating the steering wheel wave wheel, due to the friction member continuously contacting the bottom surface of the disc of the fixed shaft of the wave wheel under the action of the spring, the fixed shaft of the wave wheel quickly stops rotating under the friction of the friction member, causing the steering wheel wave wheel to stop rotating.
[0013] The beneficial effects of the present utility model compared with the prior art are as follows:
[0014] 1. The present utility model uses an encoder to replace the mechanical transmission mechanism, greatly reducing the volume of the entire mechanism. The entire steering device is installed on the armrest of the seat and rotates with the seat. Whether the driver chooses logging operations or drives the vehicle to travel, the vehicle steering can be controlled through the steering wheel, greatly improving the logging efficiency.
[0015] 2. The present utility model can quickly stop the steering wheel wave wheel after the driver stops operating by using a spring and a friction member, avoiding incorrect actions of the steering wheel wave wheel. Description of the Drawings

Detailed Embodiment
[0020] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many of the details listed in this specification are merely provided to help readers gain a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.
[0021] like Figures 1-3 As shown, a pulsator steering device for a forest logging vehicle includes a steering wheel housing 1, an aviation joint 2, an encoder 3, an encoder fixing seat 4, a bearing seat 5, a pulsator fixing shaft 6, and a steering wheel pulsator 7. The steering wheel housing 1 is vertically arranged, its interior is hollow, and a mounting hole penetrating the interior is opened on the lower left wall. The bottom surface of the steering wheel housing 1 is mounted on the armrest of the rotating seat of the logging vehicle, so that the entire steering device can rotate with the rotating seat; the encoder 3 is vertically arranged, and its housing is fixed in the steering wheel housing 1 through the encoder fixing seat 4. The encoder 3 is used to convert the rotation into an electronic signal; the lower portion of the bearing seat 5 is fixed It is fixedly arranged in the upper part of the steering wheel housing 1; the impeller fixed shaft 6 is rotatably arranged in the bearing seat 5. The impeller fixed shaft 6 consists of a disc and a connecting shaft. The disc is sleeved on the upper part of the connecting shaft. The lower part of the connecting shaft of the impeller fixed shaft 6 is connected to the rotating shaft of the encoder 3, and the upper disc extends out of the top surface of the bearing seat 5; the middle part of the steering wheel impeller 7 is fixedly connected to the top surface of the connecting shaft of the impeller fixed shaft 6 by bolts, and the disc of the impeller fixed shaft 6 can support the steering wheel impeller 7; the aviation connector 2 is horizontally arranged in the mounting hole of the steering wheel housing 1 and is electrically connected to the encoder 3 and the control system. The aviation connector 2 is used to read the signal from the encoder 3. When the driver rotates the steering wheel impeller 7, the rotating shaft of the impeller fixed shaft 6 is driven to rotate. The impeller fixed shaft 6 drives the encoder 3 to rotate. The encoder 3 converts the rotation into an electronic signal, which is read through the aviation connector 2.
[0022] The impeller fixed shaft 6 is rotatably arranged in the bearing seat 5 through the bearing 8, which is used to support the impeller fixed shaft 6 to ensure its smooth rotation.
[0023] There are two bearings 8, which are stacked up and down, which can disperse the load, provide more stable support, reduce the swing and shaking of the impeller fixed shaft 6, and improve the service life.
[0024] The impeller fixed shaft 6 is connected to the rotating shaft of the encoder 3 through the coupling 9, and the impeller fixed shaft 6 drives the encoder 3 to rotate through the coupling 9; through the flexibility of the coupling 9, the counterweight error between the impeller fixed shaft 6 and the encoder 3 is reduced, ensuring the smoothness and accuracy of the transmission process.
[0025] It further includes an encoder 3 indicator light; a connection hole penetrating through the interior is formed in the lower right side wall of the steering wheel housing 1; the encoder 3 indicator light is arranged in the connection hole and is connected to the encoder 3. The coding indicator light 10 is used to indicate the working state of the encoder 3 to help the driver determine whether a failure occurs.
[0026] It further includes a spring 11 and a friction member 12; a slot is provided at the top of the bearing seat 5; the spring 11 is vertically arranged in the slot, and its bottom end is fixedly connected to the bottom inside of the slot; the friction member 12 is vertically arranged, its bottom surface is fixedly connected to the top surface of the spring 11, and its top surface contacts the bottom surface of the disc of the wave wheel fixed shaft 6. By arranging the spring 11 and the friction member 12, when the driver stops operating, the wave wheel fixed shaft 6 quickly stops rotating due to the action of the friction member 12, causing the steering wheel wave wheel 7 to stop rotating and avoiding incorrect actions of the steering wheel wave wheel 7.
[0027] There are two such slots, which are circumferentially spaced apart and formed on the top surface of the bearing seat 5 respectively; there are two springs 11 and friction members 12 corresponding to the slots respectively. The two springs 11 and friction members 12 can further cause the steering wheel wave wheel 7 to stop rotating quickly while not increasing the operation difficulty when the driver rotates the steering wheel wave wheel 7.
[0028] The working mode of the present utility model is as follows:
[0029] When the driver rotates the steering wheel wave wheel 7, it drives the wave wheel fixed shaft 6 to rotate. The wave wheel fixed shaft 6 drives the rotating shaft of the encoder 3 through the coupling 9. The encoder 3 converts the rotation into an electronic signal, and reads the electronic signal of the encoder 3 through the aviation connector 2 and outputs it to the control system of the logging vehicle. The control system can make corresponding controls on the steering mechanism of the logging vehicle according to the electronic signal. After the driver stops rotating the steering wheel wave wheel 7, due to the friction member 12 continuously contacting the bottom surface of the disc of the wave wheel fixed shaft 6 under the action of the spring 11, the wave wheel fixed shaft 6 quickly stops rotating under the friction of the friction member 12, causing the steering wheel wave wheel 7 to stop rotating.
[0030] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
