Description

Technical Field

[0001] The utility model relates to the technical field of transmission accessories, in particular to an oil pipe connecting seat suitable for a power shift transmission. Background Art

[0002] Off-road tire crane (referred to as off-road tire crane) as a non-road engineering machinery product, is a full-rotating crane with a lifting mechanism installed on a special chassis and heavy-duty tires. The crane is equipped with four retractable legs and can carry out light weight lifting and hoisting on flat ground without the legs. It is characterized by combining the advantages of super off-road and heavy-load transportation. It is suitable for operations in narrow and small sites, and is also suitable for lifting operations in oil fields, chemical industry, mining, wind power and other scenes.

[0003] With the continuous development of commercial vehicles, OEMs have put forward higher requirements for the functionality, reliability and modularity of power shift transmissions for construction machinery. Oil and oil pipes are an indispensable part of the hydraulic system. Oil plays a role in lubrication and heat dissipation in the transmission. Various sensors for detecting the state of oil are often directly installed on the transmission housing. As a carrier for oil, the oil pipe is often installed independently of the transmission. Most of the oil pipes are directly installed on the housing for the transmission of oil inside and outside the transmission. The oil pipe connector provides an interface for the internal and external conversion of the oil circuit, playing a connecting role.

[0004] The existing oil pipe connector currently only serves to connect the oil circuits inside and outside the transmission, preventing the oil from leaking to the outside and ensuring the normal operation of the transmission. Therefore, the optimized design of the oil pipe connector is an indispensable part of the development of power shift transmissions. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an oil pipe connecting seat suitable for a power shift transmission, so as to solve the problem that the oil pipe connecting seat in the prior art has a single function.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions to achieve the above problems: an oil pipe connector suitable for a power shift transmission, comprising a connector body, the connector body being generally in a rectangular parallelepiped shape, and also comprising an oil hole penetrating the connector body and opened along the axis direction of the connector body;

[0007] The top of the connecting seat body is an external oil pipe matching surface, and the bottom is an internal oil pipe matching surface. The external oil pipe matching surface is provided with an external oil pipe connection auxiliary threaded hole;

[0008] The oil pipe connection seat suitable for the power shift transmission also includes an oil temperature sensor threaded hole and an oil pressure sensor threaded hole opened on the side wall of the connection seat body;

[0009] An oil temperature sensor is installed in the threaded hole of the oil temperature sensor, and an oil pressure sensor is installed in the threaded hole of the oil pressure sensor;

[0010] The oil pipe connector for the power shift transmission also includes a mounting threaded hole that is opened along the axis direction of the connector body and passes through the connector body;

[0011] The oil pipe connecting seat suitable for the power shift transmission also includes an oil pipe fixing block installed on the external oil pipe matching surface, and the oil pipe fixing block is installed on the external oil pipe connection auxiliary threaded hole.

[0012] The utility model also has the following technical features:

[0013] The oil pipe connection seat suitable for the power shift transmission also includes an oil temperature sensor protection platform and an oil pressure sensor protection platform installed on the side wall of the connection seat body. The oil temperature sensor protection platform and the oil pressure sensor protection platform are both plate-shaped structures and are vertically installed on the side wall of the connection seat body;

[0014] The oil temperature sensor protection platform is located in the direction where the threaded hole of the oil temperature sensor faces the external oil pipe mating surface, and the oil pressure sensor protection platform is located in the direction where the threaded hole of the oil pressure sensor faces the external oil pipe mating surface;

[0015] The top surfaces of the oil temperature sensor protection platform and the oil pressure sensor protection platform are flush with the matching surface of the external oil pipe.

[0016] The oil temperature sensor protection platform and the oil pressure sensor protection platform are respectively provided with wiring harness tie holes;

[0017] The oil temperature sensor threaded hole and the oil pressure sensor threaded hole are respectively installed on the adjacent side walls of the connecting seat body.

[0018] Compared with the prior art, the utility model has the following technical effects:

[0019] (I) The utility model provides an oil pipe connector suitable for a power shift transmission. The internal oil pipe mating surface and the external oil pipe mating surface of the oil pipe connector are cleverly designed to connect the internal oil pipe and the external oil pipe respectively, forming a complete closed lubricating oil circuit. The internal oil pipe mating surface of the oil pipe connector fits with the flange end face of the internal oil pipe, and then the oil pipe connector bolts are passed through and tightened, so that the internal oil pipe is pressed together with the oil pipe connector on the transmission housing. The external oil pipe mating surface of the oil pipe connector fits with the external oil pipe, and the two sides of the external oil pipe are tightened and fixed by two oil pipe fixing blocks, and then the oil pipe fixing block bolts are passed through the bolt holes on the oil pipe fixing block, so that the external oil pipe is fixed on the oil pipe connector. The optimized design of the oil pipe connector meets the needs of modular development of the transmission, greatly simplifies the complexity of the transmission housing, reduces the difficulty and cost of housing manufacturing, and improves the convenience of later maintenance and replacement of the oil pipe.

[0020] (II) The oil pipe connection seat suitable for a power shift transmission provided by the utility model realizes real-time monitoring of oil temperature and oil pressure. By designing two mutually perpendicular threaded holes on the oil pipe connection seat as the threaded holes for the oil temperature sensor and the oil pressure sensor, the oil temperature sensor and the oil pressure sensor can be screwed into the holes respectively and sealed therewith. The oil temperature sensor can monitor the oil temperature of the hydraulic system in real time, avoiding excessive temperature causing a reduction in oil performance, damaging the life of components and thus shortening the life of the transmission or causing failure. The oil pressure sensor can monitor the pressure of the lubricating oil in real time, avoiding excessive pressure impacting the internal parts of the transmission, or insufficient pressure reducing the performance of the transmission. Installing the oil temperature sensor and the oil pressure sensor on the oil pipe connection seat greatly reduces the difficulty of machining the transmission housing, and further reduces the difficulty and cost of production.

[0021] (III) The oil pipe connection seat for power shift transmission provided by the utility model realizes the protection of sensors and the fixation of wiring harnesses. By designing two sensor protection platforms on the oil pipe connection seat, the oil temperature sensor and the oil pressure sensor are protected respectively. The two sensor protection platforms are both located above the sensor threaded holes. After the sensors are installed in place, the protection platforms can prevent foreign objects from falling from above the transmission to damage the sensors, causing intermittent or even interrupted signal transmission.

[0022] By setting a wire harness tie hole on the sensor protection platform, the wire harness connected to the sensor is passed through the tie hole and fixed to the protection platform. The wire harness is fixed by the tie, which reduces the hanging part and helps to reduce the risk of interference with other objects. At the same time, it prevents the wire harness from being torn due to vibration, the connector from falling off, and the signal from being interrupted.

[0031] All components in the present invention, unless otherwise specified, are components known in the prior art.

[0032] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments, and all equivalent changes made on the basis of the technical solution of the present application fall within the protection scope of the present invention.

[0033] Embodiment 1:

[0034] This embodiment provides an oil pipe connector suitable for a power shift transmission, such as Figure 1-Figure 2 As shown, it includes a connection seat body 1, which is generally in the shape of a rectangular parallelepiped, and also includes an oil hole 2 that is opened along the axis direction of the connection seat body 1 and passes through the connection seat body 1;

[0035] The top of the connecting seat body 1 is an external oil pipe matching surface 3, and the bottom is an internal oil pipe matching surface 4. The external oil pipe matching surface 3 is provided with an external oil pipe connection auxiliary threaded hole 5;

[0036] The oil pipe connection seat suitable for the power shift transmission also includes an oil temperature sensor threaded hole 6 and an oil pressure sensor threaded hole 7 opened on the side wall of the connection seat body 1;

[0037] An oil temperature sensor 8 is installed in the oil temperature sensor threaded hole 6, and an oil pressure sensor 9 is installed in the oil pressure sensor threaded hole 7;

[0038] The oil pipe connector for the power shift transmission also includes a mounting threaded hole 10 extending along the axis of the connector body 1 and penetrating the connector body 1.

[0039] The oil pipe connection seat suitable for the power shift transmission further comprises an oil pipe fixing block 11 installed on the external oil pipe matching surface 3 , and the oil pipe fixing block 11 is installed on the external oil pipe connection auxiliary threaded hole 5 .

[0040] By cleverly designing the internal oil pipe matching surface 4 and the external oil pipe matching surface 3 of the connection seat body 1, they are respectively connected to the internal oil pipe and the external oil pipe, and communicated with the oil hole 2 to complete a closed lubricating oil circuit.

[0041] The internal oil pipe matching surface 4 of the connector body 1 fits with the flange end surface of the internal oil pipe, and then the oil pipe connector bolts are passed through the mounting threaded holes 10 and tightened, so that the internal oil pipe is pressed against the transmission housing 17 together with the connector body 1.

[0042] The external oil pipe mating surface 3 of the connecting seat body 1 fits with the external oil pipe, and the two sides of the external oil pipe are tightened and fixed by two oil pipe fixing blocks 11, and then the oil pipe fixing block bolts are passed through the bolt through holes of the oil pipe fixing block 11, thereby fixing the external oil pipe on the connecting seat body 1.

[0043] By designing two mutually perpendicular threaded holes on the oil pipe connection seat as the oil temperature sensor threaded hole 6 and the oil pressure sensor threaded hole 7, the oil temperature sensor and the oil pressure sensor can be screwed into the holes respectively and sealed with them. The oil temperature sensor can monitor the oil temperature of the hydraulic system in real time, avoiding the reduction of oil performance due to excessive temperature, damaging the life of parts and thus shortening the life of the transmission or failure. The oil pressure sensor can monitor the pressure of the lubricating oil in real time, avoiding the impact of excessive pressure on the internal parts of the transmission, or insufficient pressure on the performance of the transmission.

[0044] As a preferred embodiment of this invention:

[0045] The oil pipe connection base suitable for the power shift transmission also includes an oil temperature sensor protection platform 12 and an oil pressure sensor protection platform 13 installed on the side wall of the connection base body 1. The oil temperature sensor protection platform 12 and the oil pressure sensor protection platform 13 are both plate-shaped structures and are vertically installed on the side wall of the connection base body 1;

[0046] The oil temperature sensor protection platform 12 is located in the direction of the oil temperature sensor threaded hole 6 toward the external oil pipe matching surface 3, and the oil pressure sensor protection platform 13 is located in the direction of the oil pressure sensor threaded hole 7 toward the external oil pipe matching surface 3;

[0047] The top surfaces of the oil temperature sensor protection platform 12 and the oil pressure sensor protection platform 13 are flush with the external oil pipe matching surface 3 .

[0048] The oil temperature sensor protection platform 12 and the oil pressure sensor protection platform 13 protect the oil temperature sensor 8 and the oil pressure sensor 9 respectively. Both sensor protection platforms are located above the oil temperature sensor threaded hole 6 and the oil pressure sensor threaded hole 7. After the sensors are installed in place, the protection platforms can prevent foreign objects from falling from the transmission to damage the sensors, causing intermittent or even interrupted signal transmission.

[0049] As a preferred embodiment of this invention:

[0050] The oil temperature sensor protection platform 12 and the oil pressure sensor protection platform 13 are respectively provided with wire harness tie holes 14; by providing the wire harness tie holes 14 on the oil temperature sensor protection platform 12 and the oil pressure sensor protection platform 13, the wire harness connected to the sensor is passed through the wire harness tie holes 14 and fixed to the oil temperature sensor protection platform 12 and the oil pressure sensor protection platform 13 by the wire harness tie. The wire harness is fixed by the wire harness, the suspended part is reduced, which is beneficial to reducing the risk of interference with other objects, and at the same time preventing the wire harness from being torn due to vibration, the plug connector from falling off, the signal interruption and other problems.

[0051] As a preferred embodiment of this invention:

[0052] The oil temperature sensor threaded hole 6 and the oil pressure sensor threaded hole 7 are respectively installed on the adjacent side walls of the connection seat body 1. Generally speaking, the oil pipe connection seat will not be installed at the highest point of the transmission housing. If the oil temperature sensor threaded hole 6 and the oil pressure sensor threaded hole 7 are installed on the two opposite sides of the oil pipe connection seat, it may be difficult to install because one side is too close to the transmission housing.

[0053] The specific working process of this embodiment is as follows:

[0054] like Figure 3-Figure 4 As shown, the design and development principle of the fixed connection of the inner and outer oil pipes of the oil pipe connecting seat described in the utility model is as follows:

[0055] The internal oil pipe matching surface 4 and the external oil pipe matching surface 3 are cleverly designed on the connecting seat body 1, so that they are connected to the internal oil pipe 15 and the external oil pipe 16 with flange end faces respectively, and the internal and external oil pipes are connected to form a complete closed lubricating oil circuit. The internal oil pipe matching surface 4 of the oil pipe connecting seat fits with the flange end face of the internal oil pipe 15, and then the oil pipe connecting seat bolt 13 is passed through and tightened, and the internal oil pipe 15 with the flange end face is pressed and fixed on the transmission housing 17 together with the oil pipe connecting seat. The external oil pipe matching surface 3 of the oil pipe connecting seat fits tightly with the external oil pipe 16, and the external oil pipe 16 is tightened from both sides through two oil pipe fixing blocks 11, and then the oil pipe fixing block bolt 12 is passed through the bolt through hole on the oil pipe fixing block 11, so that the external oil pipe 16 is assembled on the oil pipe connecting seat. The optimized design of the fixed connection between the inner and outer oil pipes of the oil pipe connector meets the needs of modular development of the transmission, greatly simplifies the complexity of the transmission housing 17, reduces the difficulty and cost of housing manufacturing, and improves the convenience of later maintenance and replacement of the oil pipe.

[0056] The oil temperature sensor threaded hole 6 and the oil pressure sensor threaded hole 7 are designed and processed on the oil pipe connection seat, and the oil temperature sensor 8 and the oil pressure sensor 9 are screwed into the corresponding threaded holes respectively and sealed therewith. When the oil passes through the oil pipe connection seat, the oil temperature sensor 8 can monitor the temperature of the oil in the hydraulic system in real time, and feedback information to the driver for prompting, so as to avoid the system temperature being too high, which will lead to the reduction of oil performance, damage the life of parts and thus shorten the life of the transmission or failure. The oil pressure sensor 9 can monitor the pressure of the lubricating oil in real time, so as to avoid the impact of excessive pressure on the internal parts of the transmission, or the reduction of transmission performance due to excessive pressure. Installing the oil temperature sensor 8 and the oil pressure sensor 9 on the oil pipe connection seat greatly reduces the machining difficulty of the transmission housing 17, and further reduces the production difficulty and cost.

[0057] The oil temperature sensor protection platform 12 and the oil pressure sensor protection platform 13 are designed and processed on the oil pipe connection seat to protect the oil temperature sensor 8 and the oil pressure sensor 9 respectively. The oil temperature sensor protection platform 12 is located above the oil temperature sensor threaded hole 6; the oil pressure sensor protection platform 13 is located above the oil pressure sensor threaded hole 7. When the oil temperature sensor 8 and the oil pressure sensor 9 are installed in place, the oil temperature sensor protection platform 12 and the oil pressure sensor protection platform 13 can prevent foreign objects from falling from the transmission to damage the sensor, causing signal transmission interruption or even sensor damage.

[0058] By processing the harness tie holes 14 on the oil temperature sensor protection platform 12 and the oil pressure sensor protection platform 13 respectively, the harness connected to the sensor is passed through the harness tie hole 14 and fixed to the protection platform. After the harness is fixed by the harness tie, the hanging part is reduced, which is beneficial to reduce the risk of interference with other objects, and at the same time prevents the harness from being torn due to vibration, the connector from falling off, the signal from being interrupted, and other problems.

[0059] In summary, the utility model provides a detailed introduction to an oil pipe connector suitable for a power shift transmission, which realizes functions such as fixed connection of internal and external oil pipes, real-time monitoring of transmission oil temperature and oil pressure, protection of sensors and fixation of wiring harnesses.

[0060] The above technical solutions are only preferred specific implementation methods of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be thought of by any technician familiar with the field within the technical scope disclosed by the present utility model without creative work are all covered within the protection scope of the present utility model.
