The present application is directed to an externally adjustable internal bypass shock absorber that combines both the suspension function and the shock absorbing function in one unit. More particularly, the shock body houses a bypass cylinder that includes an upper bulkhead with adjuster rod pockets and check valves as well as a lower bulkhead having one or more check valves. The bypass cylinder includes one or more bypass tubes within bypass tube accepting cavities, in fluid communication with bypass adjuster valve blocks controlling the flow of hydraulic fluid within the bypass tubes. Adjuster rods are telescopically received inside the bypass adjuster block valves for controlling whether the individual oil flow ports are closed, partially open, or fully open. These adjuster rods provide an actuation means in the damper for manual or non-automatic adjustment allowing high speed and low speed as well as sway control on the external shock surface.

A shock absorber assembly including: a cylinder housing a first damper fluid and a first piston, the first piston extending out from within the cylinder; a top mount in cooperation with a distal end of the first piston; and a hydraulic jounce control damper adjacent to the top mount, the hydraulic jounce control damper defining a jounce chamber including a second damper fluid and a second piston extending out from within the jounce chamber. In response to compression of the shock absorber assembly, the second piston is configured to contact the cylinder and slide within the jounce chamber with movement of the second piston dampened by the second damper fluid.

A damper including inner and outer tubes is provided. A piston is slidably disposed within the inner tube. An intermediate tube is positioned radially between the inner and outer tubes. An intermediate channel is disposed radially between the intermediate and inner tubes. A slanted elliptical seal is positioned at an oblique angle relative to a longitudinal axis of the inner tube and divides the intermediate channel into first and second intermediate channel portions. A first control valve is in fluid communication with the second intermediate channel portion via a first intermediate tube opening. A second control valve is in fluid communication with the first intermediate channel portion via a second intermediate tube opening.

Provided is an on-demand shock stiffening system. The on-demand shock stiffening system operates to immediately stiffen the shocks in response to a user activating the system. The system may include a main body with an oil flow aperture and a flow control system that operates to restrict the flow of oil between the reservoir and the shock. The on-demand shock stiffening system may be coupled between the reservoir and the bridge of the shock and operates to restrict flow of the oil in order to stiffen the shock immediately in an on-demand manner.

A shock absorber for a vehicle including a pressure tube defining a fluid chamber, a piston body disposed within the fluid chamber, and a valve assembly. The piston body divides the fluid chamber into an upper working chamber and a lower working chamber. The piston body defines a first bleed passage and a first blowoff passage that each extend through the piston body between the upper working chamber and the lower working chamber. The valve assembly includes a restriction disc including a ring, a first finger extending radially outward from the ring, and a second finger extending radially outward from the ring. The first finger is configured to cover the first bleed passage, the first finger having a first bleed orifice, wherein the first bleed orifice remains open regardless of position of the restriction disc. The second finger is configured to at least partially cover the first blowoff passage.

A multiple degree of freedom response valve includes a valve body, a movable member, and at least three elastic members. The movable member is movably connected to the valve body. The movable member has a first liquid guide channel, and the valve body has a second liquid guide channel and a pilot channel. The elastic members are disposed at intervals around an axis of the movable member and each connected at a first end to the movable member and at a second end opposite the first end to the valve body. The elastic members are in a same plane in a radial direction of the movable member, The pilot channel is communicated with the first liquid guide channel, and the movable member is movable with respect to the valve body, so that the first and second liquid guide channels are able to be communicated or uncommunicated.

A wireless active suspension system is disclosed. The system includes at least one sensor mounted to an unsprung mass of a vehicle, the sensor having a low power wireless communication capability, the at least one sensor to send a sensor data transmission. The system also includes a controller in wireless communication with the at least one sensor, wherein the controller receives the sensor data from the at least one sensor and communicates an adjustment command to modify at least one damping characteristic of at least one damper.

A method for controlling vehicle motion is described. The method includes accessing a set of control signals including a measured vehicle speed value associated with a movement of a vehicle. A control signal associated with user-induced input is also accessed. The method compares the measured vehicle speed value with a predetermined vehicle speed threshold value to achieve a speed value threshold approach status, and then compares the set of values to achieve a user-induced input threshold value approach status. The method monitors a state of a valve within the vehicle suspension damper, and determines a control mode for the vehicle suspension damper. The method also regulates damping forces within the vehicle suspension damper.

A hydraulic damper including a piston assembly having a piston body including at least two first channels and at least two second channels. The first and second channels are sloped. A compression side of each of the first channels is positioned radially outward relative to a rebound side. A rebound side of each of the second channels is positioned radially outward relative to a compression side. At least one main disc at least partially covers the rebound side of each of the first channels, and at least one main disc at least partially covers the compression side of each of the second channels. At least one supplementary channel is positioned radially inward with respect to the first and second channels. At least one supplementary disc at least partially covers at least one of a rebound side and a compression side of the at least one supplementary channel.

An oil channel that connects, a right damper and a left damper includes a switching valve arranged between a right oil channel ER and a left oil channel EL. The switching valve includes a valve main body in which a first switching channel is formed for connecting the right oil channel ER and the left oil channel EL. The valve main body is rotatable to a first position where the first switching channel connects the right oil channel ER and the left oil channel EL to each other and to a second position different from the first position. According to this damping system, it is possible to adjust oil flow in the oil channel by performing a simple operation for the switching valve.
