By adopting the technical scheme, the first coil assembly and the second coil assembly both comprise armatures and coils arranged in the armatures, the armatures are far away from the guide rods arranged on the valve body assembly, when the coils are electrified, the armatures are close to the guide rods and move, damping oil flowing into the inner part of the shell from the damper in the stretching state and the compression state is not in the same position, but flows into the inner part of the shell through the first through hole in the stretching state, the second regulating valve is opened by the armature movement of the coil assembly at the second regulating valve, the damping oil flows into the damper again from the second through hole after passing through the second regulating valve, and in the compression state, in contrast, the damping oil flows into the inner part of the shell from the second through hole and flows back into the inner part of the damper from the first through hole again after passing through the first regulating valve, so that the first regulating valve is in the opening state.
The external damping control valve for an automobile shock absorber can be further provided with: the first governing valve is including first governing valve body, first governing valve body is equipped with the first oilhole that encircles the setting, first oilhole both ends are equipped with first boss and second boss respectively, and first boss is equipped with first clearance between adjacent first oilhole, and the second boss is equipped with the second clearance between adjacent first clearance, first governing valve body both ends all are provided with first valve block, and the valve rod is equipped with the disk seat in the first valve block department that spacer ring one end was kept away from to first governing valve body, be equipped with the second oilhole that encircles the setting on the disk seat, first coil assembly is close to disk seat department and is equipped with first valve cap, and first valve cap offsets with the disk seat when first coil assembly is unpowered.
The external damping control valve for an automobile shock absorber can be further provided with: the second governing valve is including the second governing valve body, the second governing valve body is equipped with the third oil hole that encircles the setting, third oil hole both ends are crossed to the third is equipped with third boss and fourth boss respectively, and the third boss is equipped with the third clearance between adjacent third oil hole, and the fourth boss is equipped with the fourth clearance between adjacent third clearance, second governing valve body both ends all are equipped with the second valve block, and the valve rod is equipped with the valve circle in the second valve block department of the one end that the spacer ring was kept away from to the second governing valve body, and the second coil subassembly is close to valve circle department and is equipped with the second valve cap, valve rod is close to valve circle department and is equipped with the valve rod boss, and the second valve cap offsets with the valve rod boss when second coil subassembly is unpowered.
By adopting the technical scheme, when the first coil assembly is not electrified, the first valve cap of the first coil assembly is propped against the valve seat of the first regulating valve, and the damping oil can flow into the valve body of the first regulating valve through the first gap or the second gap, but as the two ends of the first regulating valve are both provided with the first valve plate, when the valve cap is propped against the valve seat, one end of the first oil passing hole is sealed by the first valve plate, and the damping oil cannot pass through the first oil passing hole, so the first regulating valve is in a closed state, and when the first coil assembly is electrified, the first valve cap is separated from the valve seat, the damping oil can push the first valve plate, and therefore, the damping oil can pass through the first oil passing hole.
The beneficial effects of the invention are as follows: the damping regulating valve is arranged outside the shock absorber, so that the effective stroke of the shock absorber can be increased, and the damping regulating valve is sensitive in damping regulation and good in heat dissipation effect.
The invention is described in further detail below with reference to the drawings and examples.
