Description

Technical Field

[0001] This utility model belongs to the technical field of transmission connection devices, and more specifically, relates to a transmission connection adjustment device applied to a gearbox. Background Technology

[0002] The gearbox is a core component of a vehicle's transmission system. It is responsible for adjusting the engine's torque and speed, ensuring the engine operates under optimal conditions to meet the vehicle's driving and traction needs in various road conditions. Simultaneously, the gearbox allows for the separation of the engine and drive system, enhancing the vehicle's flexibility and adaptability. Against the backdrop of booming railway construction, gearboxes are increasingly widely used in railway vehicles, playing a crucial role, especially in multi-functional railway track maintenance vehicles.

[0003] Railway tracks, exposed to the natural environment for extended periods, are susceptible to erosion from wind and rain, as well as the effects of train power, leading to wear and tear on track equipment and deformation of the roadbed. Therefore, regular maintenance is essential. During maintenance, railway maintenance vehicles rely on engine-driven gearboxes for movement. However, for short-distance relocation to work sites, to reduce fuel consumption and environmental pollution, multi-purpose vehicles are often towed by a locomotive. During towing, the gearbox output shaft is constantly connected to the drive axle, causing the wheels to rotate and thus rotating the gearbox output shaft. Although the gearbox is not engaged in gear at this time, the gears in its internal clutch housing are still in a state of constant mesh with the gears on the gearbox output shaft, resulting in high-speed rotation of the clutch housing. At this point, because the gearbox lubrication pump is not working, the clutch will be damaged due to lack of lubrication, which is detrimental to the long-term use of the gearbox. Therefore, further improvements are urgently needed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing gearboxes are prone to clutch damage and are not conducive to the long-term use of the gearbox because the output shaft is constantly connected to the drive axle during towing.

[0005] To achieve the above objectives, this utility model provides a transmission connection adjustment device for a gearbox, used to adjust the transmission connection state between the output shaft and the external transmission shaft of the gearbox;

[0006] The transmission connection adjustment device includes a connecting cylinder, an adjustment mechanism, and a status monitoring sensor;

[0007] The connecting sleeve is sleeved on the output shaft;

[0008] The adjustment mechanism includes a movable component and a fastener. The movable component includes a movable frame disposed on the connecting cylinder and configured to drive the connecting cylinder to move along the output shaft, so that the output shaft can be connected or disconnected from the external transmission shaft through the connecting cylinder. The fastener is used to limit the movable frame.

[0009] The status monitoring sensor is used to obtain the transmission connection status according to the moving direction of the movable frame and transmit it to the control terminal of the gearbox.

[0010] Optionally, the connecting cylinder is provided with a mounting groove for mounting the movable frame.

[0011] Alternatively, the movable frame may be shaped like a fork.

[0012] Optionally, the movable component may further include a movable shaft passing through the upper end of the movable frame and used to move the movable frame.

[0013] Optionally, the connecting cylinder is covered with a housing, and the housing is provided with a guide groove for the movement of the movable shaft.

[0014] Alternatively, one end of the movable shaft may be provided with an eye bolt for driving its movement within the guide groove.

[0015] Alternatively, the fastener includes a locking pin that passes through the housing and is used to connect with the movable shaft, a first spring that is sleeved on the locking pin, and a lug nut that is connected to the end of the locking pin.

[0055] Reference Figure 1-4 An embodiment of this utility model provides a transmission connection adjustment device for a gearbox, used to adjust the transmission connection state between the output shaft 1 of the gearbox and the external transmission shaft 2;

[0056] The transmission connection adjustment device includes a connecting cylinder 3, an adjustment mechanism, and a status monitoring sensor 4;

[0057] Connecting cylinder 3 is sleeved on output shaft 1;

[0058] The adjustment mechanism includes a movable component and fasteners. The movable component includes a movable frame 5 disposed on the connecting cylinder 3 and configured to drive the connecting cylinder 3 to move along the output shaft 1, so that the output shaft 1 can be connected or disconnected from the external transmission shaft 2 through the connecting cylinder 3. The fasteners are used to limit the movable frame 5.

[0059] The status monitoring sensor 4 is used to obtain the transmission connection status according to the moving direction of the movable frame 5 and transmit it to the control end of the gearbox.

[0060] In one specific embodiment, the connecting cylinder 3 is provided with a spline-shaped connecting groove 31 for connecting with the output shaft 1 and the external transmission shaft 2.

[0061] In one embodiment, the connecting cylinder 3 is provided with a mounting groove 32 for mounting the movable frame 5. This allows the movable frame to remain connected to the connecting cylinder while it is rotating, facilitating adjustment operations.

[0062] In one specific embodiment, the movable frame 5 is shaped like a fork.

[0063] In one embodiment, the movable component further includes a movable shaft 6 passing through the upper end of the movable frame 5 and used to move the movable frame 5.

[0064] In one embodiment, the connecting cylinder 3 is covered with a housing 7, and the housing 7 is provided with a guide groove 71 for the movement of the movable shaft 6. Specifically, one end of the housing near the output shaft is connected to the wall of the gearbox via a flange. The guide groove provides a path for the movement of the movable shaft and enhances the stability of the movable shaft during movement, thereby improving the reliability of the transmission connection adjustment device.

[0065] In one specific embodiment, one end of the movable shaft 5 is provided with an eye bolt 8 for driving it to move within the guide groove 71.

[0066] In one embodiment, the fastener includes a locking pin 9 passing through the housing 7 and for connection with the movable shaft 6, a first spring 10 sleeved on the locking pin 9, and a lug nut 11 connected to the end of the locking pin 9.

[0067] In one embodiment, the movable shaft 6 has a limiting groove 61 for limiting the locking pin 9.

[0068] Specifically, before the movable shaft needs to be moved using the eye bolt, the eye nut must be pulled to move the locking pin away from the limit groove before the movable shaft can be moved. After the movable shaft is moved, the locking pin can be reset under the action of the spring to limit the movable shaft.

[0069] In one embodiment, the status monitoring sensor 4 is installed inside the housing 7 on one side of the movable shaft 6, and the side of the sensor facing the movable shaft 6 is provided with an active contact 41 for obtaining the transmission connection status.

[0070] In one specific embodiment, the movable shaft 6 is provided with a groove 62 for placing the movable contact 41.

[0071] Specifically, when the output shaft and the external drive shaft are connected, the movable contact contacts the surface of the movable shaft, subjecting it to pressure, thereby generating a signal and transmitting it to the control terminal. When the output shaft and the external drive shaft are disconnected, the movable contact is placed within the groove; at this time, the movable contact is not subjected to external force, and therefore no signal is generated. Thus, the status monitoring sensor can sense the direction of movement of the movable shaft through the movable contact, thereby obtaining the transmission connection status and transmitting it to the control terminal of the gearbox.

[0072] In one embodiment, an activity assist component is provided on one side of the deviation state monitoring sensor 4 of the movable shaft 6.

[0073] In one specific embodiment, the activity assist component includes a second spring 12 connected at one end to the housing 7 and a steel ball 13 disposed on the second spring 12.

[0074] In one specific embodiment, the side of the movable shaft 6 facing the steel ball 13 is provided with two grooves 63 for limiting the position of the steel ball 13.

[0075] Specifically, when the movable shaft moves within the guide groove, the steel balls move from one groove to another under its influence, helping the operator to more clearly perceive the movement of the movable shaft and further improving the reliability of the transmission connection adjustment device.

[0076] In one embodiment, the end of the housing 6 connected to the gearbox is provided with an oil delivery block 14 for introducing lubricating oil from the gearbox into the housing, and the oil delivery block 14 is provided with an oil delivery channel 141.

[0077] In one embodiment, a bearing 15 for assisting the rotation of the external drive shaft 2 is provided inside the housing 6.

[0078] Specifically, the lubricating oil flows into the oil supply channel through the flange on the housing, then enters the housing through the oil inlet hole connected to the oil supply channel, and then flows to each component to be lubricated, including the bearings, in order to avoid damage to the bearings and other components due to high temperature.

[0079] The operation of the transmission connection adjustment device of this utility model is as follows: When it is necessary to disconnect the output shaft and the external transmission shaft, first pull the eye nut outward to move the locking pin away from the movable shaft. Then, push the movable shaft away from the external transmission shaft using the eye screw to disengage the connecting cylinder from the external transmission shaft. At this time, the status monitoring sensor has no signal transmission, and when the external transmission shaft rotates, it will not drive the output shaft to rotate. When it is necessary to connect the output shaft and the external transmission shaft, pull the eye nut outward again and push the movable shaft closer to the external transmission shaft using the eye screw. When the external rotating shaft rotates, the connecting cylinder can drive the output shaft to rotate synchronously. At the same time, the active contact on the status monitoring sensor is pressed, generates a signal, and outputs it to the control terminal.

[0080] The present invention proposes a transmission connection adjustment device for a gearbox, which includes a connecting cylinder, an adjustment mechanism, and a status monitoring sensor. The connecting cylinder is sleeved on the output shaft. The adjustment mechanism includes a movable component and a fastener. The movable component includes a movable frame disposed on the connecting cylinder and configured to drive the connecting cylinder to move along the output shaft, so that the output shaft can be connected or disconnected from an external transmission shaft through the connecting cylinder. The fastener is used to limit the movable frame. The status monitoring sensor is used to obtain the transmission connection status according to the movement direction of the movable frame and transmit it to the control end of the gearbox.

[0081] Therefore, compared with the existing structure where the output shaft of the gearbox is usually connected to the drive axle, this utility model can connect or disconnect the output shaft and the external drive shaft according to actual needs, so as to realize the functionality of the gearbox and also provide effective protection for the gearbox, thereby reducing the possibility of clutch damage and facilitating the long-term use of the gearbox.

[0082] While one or more embodiments of the present invention have been described above, those skilled in the art will recognize that the present invention can be implemented in any other form without departing from its spirit and scope. Therefore, the embodiments described above are illustrative and not restrictive, and many modifications and substitutions will be apparent to those skilled in the art without departing from the spirit and scope of the present invention as defined in the appended claims.
