Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a connection structure for an electromagnetic valve of an electric-controlled shock absorber. Background Art

[0002] The electronically controlled shock absorber is a new type of shock absorber that uses solenoid valve technology. The core component of the electronically controlled shock absorber is the solenoid valve. Traditional mechanical shock absorbers can usually only be adjusted according to the preset damping coefficient, while the electronically controlled shock absorber can achieve fine adjustment and optimization of the shock absorber through the control of the solenoid valve, so that the electronically controlled shock absorber has higher precision and controllability, and can achieve fine adjustment of the vehicle's shock absorbing effect, which can effectively improve the vehicle's stability and handling, thereby further improving the vehicle's ride comfort and safety.

[0003] The solenoid valve of the electronically controlled shock absorber is composed of a solenoid valve body, a solenoid valve shell, a mounting seat, etc., and the solenoid valve body is covered with an outer shell. The lower end face of the outer shell has a thread, which is tightened with the inner thread of the mounting seat, and the outer end is fixed to the wiring harness plug by a clamp ring and a slot. However, the wiring harness socket is fixed by the clamp ring and the slot, which cannot limit the rotation of the wiring harness plug. The rotating wiring harness plug drives the wiring harness to rotate and interfere with the surrounding parts, or even wear and damage. Moreover, the wiring harness plug is fixed by the clamp ring and the slot, the structure is relatively complex and difficult to disassemble, which is not conducive to assembly. Utility Model Content

[0007] The gland includes a left gland and a right gland that are detachably connected. The gland formed by connecting the left gland and the right gland is provided with a snap-in hole that can be snap-fitted with the outer contour of the top of the wiring harness plug. The left gland and the right gland are both covered on the top of the wiring harness plug and the top of the solenoid valve seat.

[0008] The left and right glands are arranged on the top of the wiring harness plug and the top of the solenoid valve seat and locked together, so that the gland formed by the connection of the left and right glands is stably fixed on the solenoid valve seat, and the wiring harness plug is in the clamping hole, and the gland will not have axial and radial movement, thereby preventing the wiring harness plug from having axial and radial movement on the solenoid valve seat. At the same time, since the gland is composed of a detachable left and right gland, it is convenient for early adjustment, disassembly, replacement and later local maintenance of the solenoid valve assembly, thereby improving work efficiency.

[0009] Preferably, the left pressure cover and the right pressure cover are both semicircular cover bodies, and corresponding earrings are provided at both ends of the left pressure cover and the right pressure cover, and the opposite earrings are connected by bolts.

[0010] Preferably, a draft portion is provided on the inner walls of the left and right glands that are in contact with the outer wall of the solenoid valve seat.

The guide column 22 extends outward from the valve core 21 and is coaxially inserted into the wiring harness plug 3. The outer wall at the bottom of the valve core 21 is provided with an external thread connected to the internal thread.

[0031] Furthermore, an O-ring 5 is provided on the valve core 21, so that the valve core 21 is sealed and connected to the inner wall of the electromagnetic valve seat 1, ensuring that the oil does not enter the electromagnetic coil through the side and cause a short circuit.

[0032] The wiring harness plug 3 includes a plug section 31 and a sleeve section 32 . The plug section 31 is arranged on the upper part of the sleeve section 32 . The sleeve section 32 is coaxially sleeved in the solenoid valve seat 1 . The guide column 22 is coaxially inserted in the sleeve section 32 .

[0033] Furthermore, the outer side of the bottom of the sleeve section 32 is concavely provided with a coil winding area 321 .

[0034] The gland 4 comprises a left gland 41 and a right gland 42 which are symmetrically and detachably connected. The gland 4 formed by connecting the left gland 41 and the right gland 42 is provided with a snap-in hole 401 which can be snap-fitted with the outer contour of the plug section 31 of the wiring harness plug 3. The left gland 41 and the right gland 42 are both semicircular cover bodies and are covered on the sleeve section 32 of the wiring harness plug 3 and the top of the solenoid valve seat 1; the two ends of the left gland 41 and the right gland 42 are provided with corresponding earrings 402, and the opposite earrings 402 are connected by bolts.
