Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle shock absorption, and particularly relates to a modified external solenoid valve shock absorber with a detachable structure. Background Technique

[0002] As an unconventional shock absorber, the solenoid valve shock absorber is a new type of damping adjustable shock absorber that continuously changes the throttle opening through a pilot-operated proportional solenoid valve to achieve continuous damping adjustment. The solenoid valve shock absorber includes an external solenoid valve shock absorber and an internal solenoid valve shock absorber. The solenoid valve and its peripheral components of the external solenoid valve shock absorber include a solenoid valve seat, a solenoid valve assembly placed inside the solenoid valve seat, and a gland for fixing the solenoid valve body inside the solenoid valve seat. The solenoid valve seat is fixedly connected to the outside of the oil storage cylinder. Since most vehicles will not disassemble and assemble the shock absorber after leaving the factory, for the current external solenoid valve shock absorbers on the market, even if the connection between the solenoid valve seat and the gland is detachable, its outer periphery is smooth without clamping points, making disassembly and assembly difficult.

[0003] However, for some users with modification needs, they need to frequently change the solenoid valve specifications to meet the modification performance. Therefore, they need to frequently open the solenoid valve gland and the solenoid valve seat. The existing external solenoid valve shock absorbers are inconvenient for disassembly and assembly due to the lack of clamping points on the outer periphery of the solenoid valve seat and the gland, and cannot well meet the usage requirements of such users. Content of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the purpose of the utility model is to provide a modified external solenoid valve shock absorber with a detachable structure, which is used to solve the technical problems that the current external solenoid valve shock absorbers are inconvenient for disassembly and assembly and cannot well meet the needs of modified vehicles.

[0005] To achieve the above purpose, the technical solution of the utility model is: a modified external solenoid valve shock absorber with a detachable structure. The external solenoid valve shock absorber includes an oil storage cylinder, a solenoid valve seat connected to the outside of the oil storage cylinder, a solenoid valve assembly placed inside the solenoid valve seat, and a solenoid valve gland. The solenoid valve gland and the solenoid valve seat are detachably connected through thread matching. At least two card slots are provided on the outer periphery of the end of the solenoid valve gland, and the card slots are evenly distributed along the outer periphery of the solenoid valve gland.

[0006] Preferably, four card slots are provided.

[0007] Preferably, the depth of the card slot is 10 mm.

[0008] Preferably, the width of the card slot is 5 mm.

[0009] Preferably, the solenoid valve seat and the oil storage cylinder are fixedly connected by welding.

[0010] The beneficial effects of adopting the technical solution of the present utility model are as follows:

[0011] In the present utility model, a clamping groove is provided on the outer periphery of the solenoid valve gland. By clamping the torque tooling in the clamping groove and applying a torsional force, the solenoid valve gland can be easily opened, facilitating the replacement of the solenoid valve assembly and meeting the performance requirements of modified vehicles.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments, and do not limit the scope of the present utility model.

[0018] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present utility model.

[0019] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] The specific embodiments are as follows:

[0021] Embodiment 1, as Figures 1-4 shown, a modified external solenoid valve shock absorber with a detachable structure, the external solenoid valve shock absorber includes a storage oil cylinder 4, a solenoid valve seat 3, a solenoid valve assembly 1, and a solenoid valve gland 2. An intermediate cylinder and a working cylinder are arranged in the storage oil cylinder 4 to form a shock absorber assembly. The solenoid valve seat 3 is connected outside the storage oil cylinder 4, the solenoid valve assembly 1 is assembled in the solenoid valve seat 4, and is connected to the solenoid valve seat 3 through the solenoid valve gland 2 to fix the solenoid valve seat 4.

[0022] The detachable connection between the solenoid valve gland 2 and the solenoid valve seat 3 is realized through thread matching, so as to facilitate the removal of the solenoid valve assembly for replacement. A clamping groove 21 is arranged on the outer periphery of the end of the solenoid valve gland 2. At least two clamping grooves 21 are provided and are evenly distributed along the outer periphery of the solenoid valve gland 2. The arrangement of the clamping groove 21 facilitates the clamping of the torque tooling, and by rotating the torque tooling, the solenoid valve gland 2 can be easily opened, which is more suitable for users with modification requirements for vehicles.

[0023] When the modified external solenoid valve shock absorber with a detachable structure in this embodiment is in use, for some vehicles that are often modified, it is necessary to replace the solenoid valve assembly 1 and the intermediate cylinder and the working cylinder in the storage oil cylinder 4. By clamping the torque tooling on the clamping groove 21 of the solenoid valve gland 2 and rotating the torque tooling, the disassembly and assembly of the solenoid valve gland 2 can be easily realized, so as to realize the replacement of the solenoid valve assembly 1 and meet the requirements of users with modification needs who need to often replace the specifications of the solenoid valve assembly 1 to meet the modification performance.

[0024] Furthermore, the number of the clamping grooves 21 is preferably set to four to ensure better compliance with the structural characteristics of the solenoid valve gland.

[0025] Furthermore, since the solenoid valve used on the current external solenoid valve shock absorber has a thread standard of M35*1.5 for the solenoid valve seat 3 and the solenoid valve gland 2, the effective length of the external thread 31 is 15 mm, and the effective length of the internal thread 22 is 9 mm. Therefore, to match the tightening torque of the above threads, the depth of the clamping groove 21 in the axial direction of the solenoid valve gland 2 is set to 10 mm, and the width of the clamping groove 21 is set to 5 mm.

[0026] Furthermore, the solenoid valve seat 3 and the oil storage cylinder 4 are fixedly connected by welding to ensure the reliability of the connection.

[0027] The above has made an exemplary description of the present utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various non-substantive improvements are made by adopting the technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
