Abstract
The utility model relates to an anti-foaming shock absorber for an automobile. The anti-foaming shock absorber comprises an outer cylinder and an inner cylinder; a piston valve module, a bottom valve module and a piston rod are arranged in the inner cylinder; the piston valve module is arranged on the piston rod; the bottom valve module is arranged at the bottom of the inner cylinder; the upper end of the inner cylinder is provided with a guider and an oil seal; the guider is sleeved on the piston rod; the oil seal is arranged on the guider; an oil guide channel is arranged between the oil seal and the guider; the oil guide channel comprises an inflow channel, an outflow channel and a cushion chamber; one end of the inflow channel is communicated with the inner cylinder, and the other end of the inflow channel is communicated with the cushion chamber; one end of the outflow channel is communicated with the cushion chamber, and the other end of the outflow channel is communicated with the outer cylinder; and the inner wall of the cushion chamber is provided with a guide baffle opposite to the inflow channel. By the technical scheme, the anti-foaming shock absorber for the automobile can prevent oil from foaming when the oil flows to the outer cylinder, so that the shock absorber works stably.
Description
Technical field
The utility model relates to the auto parts machinery field, particularly a kind of anti-foamed type automobile absorber.
Background technique
At present, existing automobile absorber includes outer shell, inner casing, is provided with piston valve assembly, bottom valve assembly, piston rod in the inner casing; The piston valve assembly is arranged on the piston rod, and bottom valve assembly is arranged on the inner casing bottom, and the inner casing upper end also is provided with guider, oil sealing, and guider is set on the piston rod; Oil sealing is arranged on the guider, and wherein, guider is provided with oil guiding hole, and the oil guiding hole two ends are communicated with inner casing, outer shell respectively; The downward-sloping setting of pod apertures is when the automobile absorber of this structure, fluid flow to outer shell from pod apertures; Impact excessively, occur the foamed phenomenon easily, and then cause the vibration damper damping effect bad.
Summary of the invention
The purpose of the utility model: in order to overcome the defective of existing technology, the utility model provides a kind of anti-foamed type automobile absorber, occurs the foamed phenomenon in the time of avoiding fluid to flow to outer shell, and then guarantees the vibration damper working stability.
The technological scheme of the utility model: a kind of anti-foamed type automobile absorber, include outer shell, inner casing, be provided with piston valve assembly, bottom valve assembly, piston rod in the inner casing; The piston valve assembly is arranged on the piston rod, and bottom valve assembly is arranged on the inner casing bottom, and the inner casing upper end also is provided with guider, oil sealing; Guider is set on the piston rod, and oil sealing is arranged on the guider, is provided with the Oil Guide passage between described oil sealing and the guider; Described Oil Guide passage includes flow channel, flow pass and buffer cavity; Flow channel one end and inner casing conducting, the other end and buffer cavity conducting, flow pass one end and buffer cavity conducting; The other end and outer shell conducting, corresponding flow channel position is provided with the drainage baffle plate on the described buffer cavity inwall.
Adopt technique scheme, through the drainage baffle plate that is provided with, after fluid gets into from flow channel; Impact is on the drainage baffle plate, and the drainage baffle plate bears fluid and impacts, and the drainage baffle plate is introduced fluid in the buffer cavity; Flow to outer shell by flow pass again; Fluid after the drainage of drainage baffle plate impacts little, thereby the foamed phenomenon occurs can avoid fluid to flow to outer shell the time, and then guarantees the vibration damper working stability.
The further setting of the utility model: the end face that described drainage baffle plate is positioned at flow channel one side is a drainage face, and described drainage face is provided with perpendicular to the flow channel direction.
Adopt above-mentioned further setting, the drainage baffle plate set-up mode of this structure can reduce the impact of fluid most effectively.
Further being provided with again of the utility model: be provided with guide pin bushing between described guider and the piston rod.
Adopt above-mentioned further setting again, the guide sleeve of setting can guarantee that piston rod moves vertically.
