Detailed Description
The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.
In the present embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right side", "left end", "above", "back", "middle", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description of the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In the present embodiment, if the connection or fixing manner between the components is not specifically described, the connection or fixing manner may be a bolt fixing manner, a pin connecting manner, or the like, which is commonly used in the prior art, and therefore, details thereof are not described in the present embodiment.
Examples
An oil pressure solenoid valve suitable for an automatic transmission comprises a solenoid valve shell 1 with a coil inside, a valve core sleeve 2 clamped and fixed with the solenoid valve shell 1, and a valve core 3 arranged inside the valve core sleeve 2 and extending to the inside of the solenoid valve shell 1 with one end, wherein a spring force adjusting device 4 used for adjusting the oil pressure range of the solenoid valve is further arranged on the valve core sleeve 2, as shown in fig. 1.
As shown in fig. 2, a rotary clamping seat 21 is arranged at one end of the valve core sleeve 2 sleeved with the electromagnetic valve housing 1, and after the rotary clamping seat 21 is embedded into the electromagnetic valve housing 1, the rotary clamping seat 21 and the electromagnetic valve housing 1 are clamped and fixed by rotating the valve core sleeve 2, so that the purpose of quick installation is achieved.
As shown in fig. 3 to 4, the spring force adjusting device 4 includes a cylindrical nut 41 that is screwed with the valve core sleeve 2, an adjusting screw 42 that is screwed and fixed inside the cylindrical nut 41, and a spring 43 that is disposed inside the cylindrical nut 41. The cylindrical nut 41 comprises a nut body 411, a first internal thread 412 which is arranged at one end inside the nut body 411 and is used for being matched with the valve core sleeve 2 to be screwed and fixed, and a second internal thread 413 which is arranged at the other end inside the nut body 411 and is used for being matched with the adjusting screw 42 to be screwed and fixed. The adjusting screw 42 is provided with an external thread 421 matched with the cylindrical nut 41, and the end face of the adjusting screw 42 is provided with a straight groove 422 convenient for screwing. One end of the spring 43 abuts against the valve body 3, and the other end abuts against the adjusting screw 42.
By changing the position of the adjusting screw 42 in the cylindrical nut 41, the spring 43 is contracted or expanded, thereby changing the spring force. When the force of the electromagnetic valve is set to a certain value, the two ends of the valve core 3 are stressed in balance, the oil pressure is output constantly, but under the condition that the force of the electromagnetic valve is not changed, the spring force is changed, the original stress balance of the valve core is broken, the relative position of the valve core is changed, and the oil pressure is changed at the same time.
The utility model discloses technical effect mainly embodies in following aspect: through install spring force adjusting device additional on the solenoid valve, through rotatory adjusting screw, the elasticity of control spring to make the adjustable oil pressure scope grow of solenoid valve or diminish, can change the pressure of solenoid valve oil pressure, in addition, when spring force adjusting device cooperation solenoid valve was moved, be favorable to reducing the degree of difficulty of maintenance automatic gearbox, improve the maintenance success rate.
Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
