Abstract
The present disclosure relates to a hydraulic vehicle height adjustment device including a storage tank part configured to store a fluid, a housing part connected to the storage tank part and configured to define a flow path portion through which the fluid moves, a gear pump part inserted into the housing part and having gears configured to press the fluid, an electric motor part mounted on the housing part and configured to operate the gear pump part when electric power is applied, an adjustment part connected to the housing part and configured to change a height of a vehicle body by using hydraulic pressure, and a pulsation reducing part inserted into the housing part, connected to the flow path portion, and configured to maintain a constant movement amount of the fluid.
Claims18
A hydraulic vehicle height adjustment device comprising:
- a storage tank part configured to store a fluid;
- a housing part connected to the storage tank part and configured to define a flow path portion through which the fluid moves;
- a gear pump part inserted into the housing part and having gears configured to press the fluid, wherein the gears rotate to press the fluid and discharge the fluid with increased pressure;
- an electric motor part mounted on the housing part and configured to operate the gear pump part when electric power is applied;
- an adjustment part connected to the housing part and configured to change a height of a vehicle body by using hydraulic pressure;
- and
- a pulsation reducing part inserted into the housing part, connected to the flow path portion, and configured to maintain a constant movement amount of the fluid, wherein the pulsation reducing part comprises:
- a reduction insertion part inserted into the housing part and configured to mitigate fluid impact while guiding the fluid, which is introduced into a pulsation inlet portion, to a pulsation outlet portion;
- and
- a reduction support part mounted on the housing part and configured to support the reduction insertion part.
A hydraulic vehicle height adjustment device comprising:
- a storage tank part configured to store a fluid;
- a gear pump part connected to the storage tank part and having gears configured to operate to press the fluid, wherein the gears rotate to press the fluid and discharge the fluid with increased pressure;
- a pulsation reducing part configured to maintain a constant movement amount of the fluid discharged from the gear pump part;
- an adjustment valve part connected to the pulsation reducing part and configured to control a movement amount of the fluid to an adjustment part for changing a height of a vehicle body;
- and
- a check valve part disposed between the pulsation reducing part and the gear pump part and configured to control the movement amount of the fluid.
A hydraulic vehicle height adjustment device comprising:
- a storage tank part configured to store a fluid;
- a housing part connected to the storage tank part and having a flow path portion through which the fluid moves;
- a gear pump part inserted into the housing part and having gears configured to press the fluid, wherein the gears rotate to press the fluid and discharge the fluid with increased pressure;
- an electric motor part mounted on the housing part and configured to operate the gear pump part when electric power is applied;
- a valve part inserted into the housing part and configured to open or close the flow path portion;
- and
- a control part mounted on the housing part and configured to operate the valve part,
- wherein the hydraulic vehicle height adjustment device includes:
- a pulsation reducing part inserted into the housing part, connected to the flow path portion, and configured to maintain a constant movement amount of the fluid;
- and
- a check valve part disposed between the pulsation reducing part and the gear pump part and configured to control the movement amount of the fluid,
- wherein the pulsation reducing part comprises:
- a reduction insertion part inserted into the housing part and configured to mitigate fluid impact while guiding the fluid, which is introduced into a pulsation inlet portion, to a pulsation outlet portion;
- and
- a reduction support part mounted on the housing part and configured to support the reduction insertion part.
