Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, and in particular to a hydraulic control structure for a dual-clutch gearbox. Background Technology

[0002] Dual-clutch transmissions differ from conventional automatic transmission systems. While based on manual transmissions, they are not automatic. Besides offering the flexibility of a manual transmission and the comfort of an automatic, they provide uninterrupted power output. The hydraulic control structure of a dual-clutch transmission is primarily used for detecting and transmitting pressure. For example, as shown in the dual-clutch transmission valve body hydraulic testing device in Chinese patent application CN201410155784.5, a pressure sensor suitable for measuring oil pressure is installed on the sensor oil passage plate. The first surface of the sensor oil passage plate is fixedly mounted to the actuator valve body via a first partition, and the second surface of the sensor oil passage plate opposite to the first surface is fixedly mounted to the solenoid valve body via a second partition.

[0003] However, when using a control module to control an integrated circuit board, using a single pressure sensor makes it inconvenient to transmit data to the integrated circuit board; in addition, the control module is fixed to the integrated circuit board and cannot be disassembled, which makes it inconvenient to quickly replace or remove the control module. Utility Model Content

[0004] To address the issues raised in the background section regarding the inconvenience of using a single pressure sensor for data transmission to the integrated circuit board, and the difficulty in quickly replacing or disassembling the control module due to its fixed position on the integrated circuit board, this invention provides the following technical solution:

[0005] A hydraulic control structure for a dual-clutch transmission includes an integrated circuit board. A pressure sensor for transmitting pressure to the integrated circuit board is provided at the top of the integrated circuit board. A fixing device for fixing a control module is provided on the right side of the integrated circuit board. A wiring harness for connecting to the pressure sensor is provided at the top of the control module, and there are several wiring harnesses.

[0006] The fixing device includes a connecting component fixedly installed on the integrated circuit board for mounting the control module. Above the connecting component, there is a fixing component for fixing the control module. There are two fixing components. Inside the control module, there is a folding component for folding and storing the fixing components.

[0007] Furthermore, the control module has storage slots on the front and rear sides for storing the folding components, and sliding grooves on the left and right sides of the storage slots for assisting the folding components in folding and storing.

[0008] Furthermore, the connection assembly includes a connection plate fixedly installed on the right end of the integrated circuit board, and a fixing frame for mounting the control module is fixedly installed on the right end of the connection plate.

[0009] Furthermore, the folding assembly includes a slider that slides up and down within a groove, and the end of the slider away from the groove is hinged to a hinge rod for driving the fixing assembly to fold.

[0010] Furthermore, the fixing assembly includes a fixing plate movably connected to the storage slot, and a hinge block for hinged to the hinge rod is fixedly installed at the top of the fixing plate, and there are two hinge blocks.

[0011] Furthermore, the top of the fixing plate is provided with a settling screw for locking the fixing plate, and there are two settling screws, which are symmetrically arranged from left to right and pass through the plate body of the settling screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By setting a fixed device, the current design is a DCT dual-clutch design, with one pressure sensor for each of the odd-numbered and even-numbered clutches. This design reduces the pressure sensor for even-numbered gears by using a single pressure sensor because it does not collect oil pressure in real time. The solution for the eliminated pressure sensor is to organize the existing data and transmit regular fixed values ​​to the whole vehicle.

[0014] In addition, when it is necessary to fix the control module, the slider can slide in the slide groove, and with the hinged connection between the hinge rod and the hinge block, and with the support of the hinge rod, the fixing plate in the storage slot can be unfolded. Then, the fixing plate can be fixed to the frame of the fixed frame using two sinker screws, which can realize the quick replacement and disassembly of the control module.

[0030] Please see Figures 1-5 This utility model provides a hydraulic control structure for a dual-clutch transmission.

[0031] The system includes an integrated circuit board 100, with a pressure sensor 300 at its top for transmitting pressure to the integrated circuit board 100. A fixing device 400 for securing the control module 200 is located on the right side of the integrated circuit board 100. Several wiring harnesses 500 are provided at the top of the control module 200 for connecting to the pressure sensor 300. This allows for electrical signal connection between the control module 200 and the pressure sensor 300 using multiple wiring harnesses 500, and then the final pressure value is transmitted to the vehicle. The current design is a DCT dual-clutch design, with one pressure sensor 300 for each of the odd-numbered and even-numbered clutches. To eliminate one pressure sensor 300 for even-numbered clutches, a single pressure sensor 300 is used because it does not collect oil pressure in real time. The solution for eliminating the pressure sensor 300 is to organize the existing data and transmit a regular, fixed value to the vehicle.

[0032] The control module 200 has storage slots 201 on the front and rear sides for storing the folding component 420, and sliding grooves 202 on the left and right sides of the storage slots 201 for assisting the folding component 420 in folding and storing.

[0033] The fixing device 400 includes a connecting component 410 fixedly installed on the integrated circuit board 100 for mounting the control module 200. A fixing component 430 for fixing the control module 200 is provided above the connecting component 410. There are two fixing components 430. A folding component 420 for folding and storing the fixing component 430 is provided inside the control module 200.

[0034] The connecting component 410 includes a connecting plate 411 fixedly installed on the right end of the integrated circuit board 100. A fixing frame 412 for mounting the control module 200 is fixedly installed on the right end of the connecting plate 411. The inside of the fixing frame 412 is hollow so that the control module 200 can pass through the cavity of the fixing frame 410, and the control module 200 is fixed by the folding component 420 and the fixing component 430.

[0035] The folding assembly 420 includes a slider 421 that slides up and down within the slide groove 202. The end of the slider 421 away from the slide groove 202 is hinged to a hinge rod 422 for driving the fixing assembly 430 to fold. Thus, when the control module 200 needs to be fixed, the slider 421 can slide within the slide groove 202, and with the support of the hinge rod 422, the fixing assembly 430 in the storage slot 201 can be unfolded, enabling quick replacement and disassembly of the control module 200.

[0036] The fixing assembly 430 includes a fixing plate 431 movably connected to the storage slot 201. A hinge block 432 for hinged to the hinge rod 422 is fixedly installed at the top of the fixing plate 431. There are two hinge blocks 432, symmetrically fixed to the top of the fixing plate 431. Two sinker screws 433 are provided at the top of the fixing plate 431 for locking the fixing plate 431. These two sinker screws 433 symmetrically penetrate the plate body of the fixing plate 431. The control module 200 is connected to the mounting plate 431 by a thread; thus, when it is necessary to fix the control module 200, the slider 421 can slide in the slide groove 202, and with the hinge connection between the hinge rod 422 and the hinge block 432, the mounting plate 431 in the storage slot 201 can be unfolded under the support of the hinge rod 422. Then, the mounting plate 431 can be fixed to the frame of the fixing frame 412 by two sinker screws 433, so that the control module 200 can be quickly replaced and disassembled.

[0037] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
