Abstract
Disclosed is a damper automatically preventing a car body from being inclined. A one-way valve of the damper is installed at the bottom of a piston and working cylinders. The hydraulic damper adopts the dual-cylinder design, wherein the first working cylinder and the second working cylinder are separated by a piston. The first working cylinder and the second working cylinder are sleeved with the third working cylinder. The piston is connected with a damper sleeve and an upper hanging ring through a piston rod. The outer wall of the third working cylinder is connected with a lower hanging ring. By the adoption of the damper, the phenomenon that the car body is inclined due to the fact that the left wheel stress and the right wheel stress are not balanced when a car turns a corner can be avoided, the discomfort of riders is lowered, different damping forces of stretching and compressing can be automatically controlled and adjusted by the hydraulic damper, electronic control is not needed any more, and the cost is lowered.

Outstanding technique effect of the present invention is:
1, have specific function one-way valve can well balanced car turn time inertial force, make automobile reduce inclination, more comfortable feeling for taking is provided.
2, the damping force of stretching can be regulated in turning process, prevent automobile roll, equilibrium centrifugation power.
3, use machine automatization control principle, avoid the electronic control using highi degree of accuracy high cost, reduce automobile making cost.
Accompanying drawing explanation
Fig. 1 is the structural representation with the vibration damper automatically preventing body sway of the present invention.
Fig. 2 of the present inventionly has the one-way valve of the vibration damper automatically preventing body sway and the schematic diagram of recuperation valve.
Embodiment
Below by way of drawings and Examples, technological scheme of the present invention is described further.
As depicted in figs. 1 and 2, of the present invention have the vibration damper automatically preventing body sway, comprise hydraulic working cylinder and one-way valve control mechanism two-part, concrete structure and annexation are: a kind of vibration damper automatically preventing body sway, comprise hydraulic working cylinder and one-way valve control mechanism two-part, concrete structure and annexation are:
Described hydraulic working cylinder comprises the first clutch release slave cylinder 3, second clutch release slave cylinder 5, 3rd clutch release slave cylinder 12, clutch release slave cylinder base 11, dampener sleeve 15, upper rings 1, lower lift ring 9, piston 14, piston rod 2 and seal ring 16, concrete structure and annexation are: described first clutch release slave cylinder 3 and the second clutch release slave cylinder 5 are separated by piston 14, 3rd clutch release slave cylinder 11 is enclosed within the outside of the first clutch release slave cylinder 3 and the second clutch release slave cylinder 5, clutch release slave cylinder base 11 is arranged between the second clutch release slave cylinder 5 and the 3rd clutch release slave cylinder 12, for separating the second clutch release slave cylinder 5 and the 3rd clutch release slave cylinder 12, piston rod 2 one end is connected with piston 14, the other end is connected with dampener sleeve 15 and upper rings 1, upper rings 1 is arranged on above dampener sleeve 15, 3rd clutch release slave cylinder 12 outer wall is connected with lower lift ring 9, seal ring 16 is enclosed within piston rod 2, prevent the first clutch release slave cylinder 3 and the 3rd clutch release slave cylinder 12 leaked liquid.
Described one-way valve control mechanism comprises compression one-way valve 4, lower compression one-way valve 10, upper stretching one-way valve 13, lower stretching one-way valve 6, recuperation valve 7 and spring diaphragm 8, described upper compression one-way valve 4 and upper stretching one-way valve 13 symmetry are arranged on piston 14 both sides, spring diaphragm 8 is arranged on recuperation valve 7, stressed for balanced car left and right hydraulic damper.Recuperation valve 7 is arranged in the middle of clutch release slave cylinder base 11, and lower compression one-way valve 10 and lower stretching one-way valve 6 are arranged on recuperation valve 7 both sides.
Described one-way valve has 4, is respectively compression one-way valve 4, lower compression one-way valve 10, upper stretching one-way valve 13 and lower stretching one-way valve 6.
Described one-way valve is that Stainless Steel Ball is combined with spring.
Working principle:
Working principle utilizes upper compression one-way valve 4 and upper stretching one-way valve 13 to control the fluid flow that the first clutch release slave cylinder 3 flows to the second clutch release slave cylinder 5, lower compression one-way valve 10 controls with lower stretching one-way valve 6 fluid flow that second clutch release slave cylinder 5 flows to the 3rd clutch release slave cylinder 12, the damping of two hydraulic damper about regulating when turning, recuperation valve 7 and the effect of spring diaphragm 8 are flow direction second clutch release slave cylinders 5 of prevention the 3rd clutch release slave cylinder 12, the liquid of the second clutch release slave cylinder 5 can flow to the 3rd clutch release slave cylinder 12, hydraulic damper is finally made to realize stretching damping by recuperation valve 7 and spring diaphragm 8 large, compression damping is relatively little, and then stop the over-tilting of automobile.
Working procedure:
When automobile turns left, because automobile does curvilinear motion, be subject to the effect such as centrifugal force and frictional force, automobile left side has the trend lifted, and will make tilting of automobile.When turning left, first clutch release slave cylinder 3 liquid of left side hydraulic damper flows to the second clutch release slave cylinder 5 by upper stretching one-way valve 13,3rd clutch release slave cylinder 12 liquid flows to the second clutch release slave cylinder 5 by lower stretching one-way valve 6,2 passages are so just only had to flow for liquid, left side hydraulic damper damping is now large, and just stop hydraulic damper to continue to stretch, right side hydraulic damper compresses just to keep original damping, so just balance the centrifugal force of automobile left side, make automobile unduly Right deviation.With should Automobile Right turn time, the damping of right side hydraulic damper is large, and left side keeps original damping, stops automobile left-leaning.
