Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a plastic hydraulic control module. Background Art

[0002] With the rapid advancement of automotive technology, competition in the automotive industry is becoming increasingly fierce. This is accompanied not only by the iteration of new products but also by increasingly stringent requirements for lightweighting. Therefore, a design solution that meets both technical requirements and lightweighting is becoming increasingly important. Coincidentally, the requirements for hydraulic control systems are also becoming simpler. The hydraulic control systems required for hybrid transmissions, which are currently popular in the market, are no longer as complex as those required for traditional automatic transmissions. The gradual penetration of electrification is also requiring a reduction in the complexity of necessary hydraulic functions. This makes simplified hydraulic control designs, which were previously unsuitable for traditional automatic transmissions, more likely and necessary for application in this industry context. Traditional hydraulic control modules primarily consist of upper and lower valve plates, a separator plate, a valve core, a solenoid valve, springs, an oil filter, and a retainer. Traditional hydraulic control valve plates are made of aluminum alloy, which is heavy and does not meet lightweighting requirements. Therefore, designing a hydraulic control module that meets both technical and lightweight requirements is a pressing issue. Utility Model Content

[0022] The following is a detailed description of a plastic hydraulic control module of the present invention in conjunction with the accompanying drawings.

[0023] like Figures 1 to 6 As shown, a plastic hydraulic control module includes an upper valve plate 1, an oil channel partition plate 2 and a lower valve plate 3. The upper valve plate 1 is connected to the lower valve plate 3 through the oil channel partition plate 2. The upper valve plate 1 and the lower valve plate 3 are respectively located on the upper and lower sides of the oil channel partition plate 2. The lower valve plate 3 is made of plastic, specifically, including but not limited to composite materials with added reinforcing agents such as PA, PPA, PPS, etc. The upper valve plate 1 is connected to one or more of a suction filter, a pressure filter 4, a mechanical pump 5, a valve core 6, and a valve seat 7. Specifically, after the plastic valve plate is injection molded, various plug-in solenoid valves and some short valve cores or filters with low clearance requirements can be directly installed. According to the oil circuit layout, the filter can be directly injection molded on the plastic valve plate according to the oil circuit design or the filter can be directly cast and fixed when the plastic valve plate is injection molded. The structure connected on the upper valve plate 1 needs to be determined according to the functional design requirements.

[0024] In this embodiment, the upper valve plate 1 is made of plastic, and the oil channel partition plate 2 is made of metal. Figure 2 As shown, the upper valve plate 1 is connected to a pressure filter 4, which includes a housing 41 and a filter element 42. The housing 41 is integrally molded on the lower valve plate 3 by injection molding or is threadedly connected to the lower valve plate 3. In this embodiment, the housing 41 and the lower valve plate 3 are integrally injection molded, and the filter element 42 is connected to the housing 41. The oil channel partition plate 2 is provided with a through hole 8. The upper end of the filter element 42 passes through the through hole 8 and is connected to the upper valve plate 1. A sealing ring 9 is connected between the filter element 42 and the upper valve plate 1. In addition, the motor is used in conjunction with the functional valve core to achieve a reasonable position layout according to the design of the oil circuit. In this embodiment, the motor is set on the upper valve plate 1.

[0025] like Figure 3 As shown, the upper valve plate 1 is connected to a mechanical pump 5, which includes a drive shaft 51, an inner rotor 52 and an outer rotor 53 from the inside to the outside. A first bushing 10 is provided in the upper valve plate 1, and a second bushing 11 is provided in the lower valve plate 3.

[0026] like Figure 4As shown, the upper valve plate 1 is overmolded with a valve sleeve 13, which is made of metal. A valve core 6 is connected to the valve sleeve 13. The outer wall of the valve sleeve 13 is provided with teeth 20 or threads connected to the upper valve plate 1. In this embodiment, it is teeth 20. The valve sleeve 13 is directly injection-molded into the upper valve plate 1 during injection molding. This structure is mainly used for the installation of functional valve cores with strict and unavoidable applications, such as main oil pressure control valves, lubrication flow valves, etc.

[0027] like Figure 5 As shown, a nut 14 is molded inside the upper valve plate 1 , and the fixing bolt passes through the lower valve plate 3 and the oil channel partition plate 2 and is threadedly connected to the nut 14 .

[0028] like Figure 6 As shown, a channel 15 is provided in the upper valve plate 1, and an opening 16 is formed at one end of the channel 15 on the upper valve plate 1. The inner wall of the channel 15 and the side close to the opening 16 are covered with a valve seat 7. A stop pin 17 is inserted in the channel 15. A spring 18 and a steel ball 19 are accommodated in the channel 15. One end of the spring 18 is connected to the stop pin 17, and the other end of the spring 18 is connected to the steel ball 19. The spring 18 makes the steel ball 19 abut against the valve seat 7 and block the opening 16. This structure is mainly for the installation of a valve seat 7 with large contact force and contact impact deformation, such as a main oil pressure relief valve; the outer wall of the valve seat 7 is provided with teeth 20 or threads connected to the upper valve plate 1, which are teeth 20 in this embodiment.
