Abstract
The present disclosure relates to a damping force variable shock absorber. The damping force variable shock absorber of the present disclosure includes a cylinder, a piston rod, a rod guide tube having an inner shell and an outer shell, and a damping force adjustment assembly having a mounting block coupled to the cylinder and a solenoid valve portion mounted on the mounting block, in which the mounting block has a guide flow path formed to guide the fluid so that fluid is transmitted from an outlet of any one of the plurality of solenoid valves to the inside of the cylinder without passing through another of the solenoid valves.
Claims20
A damping force variable shock absorber, comprising:
- a cylinder;
- a piston rod reciprocating inside the cylinder;
- a rod guide tube disposed inside the cylinder, and having an inner shell and an outer shell, wherein at least a portion of the piston rod is inserted into the rod guide tube;
- and
- a damping force adjustment assembly having a mounting block coupled to the cylinder, and a solenoid valve portion mounted on the mounting block and disposed outside the cylinder,
- wherein the solenoid valve portion includes a plurality of solenoid valves, and
- the mounting block has a guide flow path configured to guide a fluid so that the fluid is transmitted from an outlet of one solenoid valve of the plurality of solenoid valves to an inside of the cylinder without passing through another solenoid valve of the plurality of solenoid valves.
A vehicle, comprising a damping force variable shock absorber which comprises:
- a cylinder;
- a piston rod reciprocating inside the cylinder;
- a rod guide tube disposed inside the cylinder, and having an inner shell and an outer shell, wherein at least a portion of the piston rod is inserted into the rod guide tube;
- and
- a damping force adjustment assembly having a mounting block coupled to the cylinder, and a solenoid valve portion mounted on the mounting block and disposed outside the cylinder,
- wherein the solenoid valve portion includes a plurality of solenoid valves, and
- the mounting block has a guide flow path configured to guide a fluid so that the fluid is transmitted from an outlet of one solenoid valve of the plurality of solenoid valves to an inside of the cylinder without passing through another solenoid valve of the plurality of solenoid valves.
