Clamp, mount tab and tether for limit strap
A two-piece limit strap clamp for use with a shock absorber and a limit strap retention device is provided. The pieces couple together around the upper end of a shock absorber. The clamp has a protrusion that extends outwardly and is adapted for attachment of the top end of a limit strap. The lower end of the limit strap may be attached to a mounting tab that is coupled to the lower mounting bracket of the shock absorber. Also disclosed is a limit strap with a tether coupled to a spring of the shock absorber to prevent the limit strap from bowing out when the shock absorber is compressed. A method of use of a limit strap with a tether is also disclosed.
CONTROL COIL OVER INTERNAL BYPASS DAMPER FOR AUTOMOTIVE SUSPENSIONS
A damper for use with an automotive coil over shock absorber. An outer damping sleeve is retained over the exterior surface of an inner body and includes a plurality of bypass ports to alternately align and unalign with bypass ports of the inner body to regulate a bypass flow of damping oil between an interior volume and an outer passage, thereby allowing variable damping control of the damper. The outer damping sleeve is connected to an internal floating piston (IFP) which rides inside the inner body. A control spring is retained for applying a force to the IFP to limit the free movement of the IFP and thereby control a damping force of the damper during the damping event. Increased pressure in the hydraulic damping oil causes the IFP to move, causing the bypass ports to open and close depending on the forces subject to the damper.
Shock Absorber Dust Gaiter with Improved Installation
A shock absorber for a vehicle suspension system may include a damper tube having an axis defining an axial direction extending between a first end and a second end, a bumper cap, and a dust gaiter operably coupled to the bumper cap. The bumper cap may have a cover portion and a retention portion. The cover portion may be operably coupled to the second end of the damper tube, and the retention portion may extend along a lateral periphery of the damper tube to an opposite end of the bumper cap relative to the cover portion. The retention portion may include a continuous ring at a distal end of the bumper cap relative to the cover portion to define a limit for movement of the dust gaiter along the bumper cap in the axial direction. The continuous ring may be retained by a plurality of fixed fingers that extend from the cover portion to the continuous ring. A movable finger is disposed between each of the fixed fingers, each instance of the movable finger having a radially extending locking tab to engage the dust gaiter. Each instance of the moveable finger has a radial deflection rate of less than about 8 N/mm.
PRELOAD COLLAR FOR A VEHICLE SUSPENSION SYSTEM
A preload collar for a vehicle spring is described. The preload collar is coupled to the shock absorber of a vehicle so that the lower end of the vehicle spring is pressing against the preload collar. The preload collar does not allow the lower end of the vehicle spring to extend toward the ground, or toward the lower end of the shock absorber, as much as it normally would. This pre-loading of the vehicle spring provides suspension lift to the vehicle.
MECHANICAL BYPASS OF A VALVE BODY
A mechanical bypass for a shock assembly is disclosed herein. The assembly has a damper chamber having a compression portion and a rebound portion. There is further an external reservoir in fluid communication with the rebound portion of the damper chamber via a flow path. A valve is coupled with the flow path, the valve to meter a flow of the working fluid through the flow path. A bypass port to the external reservoir is provided in the flow path and bypasses the valve. A mechanical relief valve is provided in the bypass port to block a fluid flow though the bypass port until a blow-off pressure that is higher than a normal operating pressure and less than a burst pressure of the damping chamber is provided thereon.
Internal bypass shock absorber
A shock absorber is provided that includes a shock body and a shaft assembly. The shock body has an inner chamber. The inner chamber is defined by a cylindrical interior surface. At least one groove is formed in the interior surface within at least one select length of the shock body. A piston of the shaft assembly is received within the inner chamber of the shock body. The piston includes valving to allow dampening matter that is received within the inner chamber to pass through the piston to allow the piston to move within the inner chamber. The at least one groove that is formed within the interior surface is configured to allow at least some of the dampening matter to bypass the valving of the piston to allow the piston to move through the at least one select length with less resistance.
Rod-end front suspension
A rod-end front suspension is provided for an off-road vehicle. The rod-end front suspension comprises a spindle assembly that is pivotally coupled with an upper suspension arm by way of a first rod-end joint and pivotally coupled with a lower suspension arm by way of a second rod-end joint. A steering rod-end joint coupled with the spindle assembly pivotally receives a steering rod. An axle assembly coupled with the spindle assembly conducts torque from a transaxle to a wheel coupled with the spindle assembly. Each of the first and second rod-end joints comprises a ball rotatably retained within a casing. The ball is fastened within a recess between parallel prongs extending from the spindle assembly. A threaded shank extending from the casing is threadably fixated with the suspension arm, such that the spindle assembly may be moved with respect to the casing and the suspension arm.
Coilover shock absorber
A coilover shock absorber includes a damper element and a coil spring, where the coilover shock absorber includes a first mount for the damper element and a second mount for the damper element, and where the coilover shock absorber includes a first seat for the coil spring and a second seat for the coil spring, where the first mount for the damper element is operatively separate from the first seat for the coil spring, where the second mount for the damper element is operatively separate from the second seat for the coil spring. The resulting inverted coilover shock absorber allows for separate load paths for the damper element and the coil spring to the chassis.
Strut mount
A strut mount includes an inner member, an outer member, and a body rubber. A stopper rubber which protrudes outward in an axial direction is disposed on the body rubber. The outer member includes a supporting portion which covers the stopper rubber from outside thereof in the axial direction. The stopper rubber includes a pedestal protrusion portion which protrudes outward in the axial direction from the inner member and a tip protrusion portion which protrudes outward in the axial direction from the pedestal protrusion portion, contacts the supporting portion, and has an elasticity in the axial direction lower than that of the pedestal protrusion portion. The pedestal protrusion portion and the tip protrusion portion taper outward in the axial direction.
ACTUATOR OR SUSPENSION
An actuator whose total length can be reduced is provided. An actuator (2) includes: a casing (7); a hollow shaft (8) rotatably supported by the casing (7) via a bearing (9a, 9b), the hollow shaft (8) including a bottom portion (8b); a screw shaft (14) coupled to the bottom portion (8b) of the hollow shaft (8), the screw shaft (14) sharing a common center line with the hollow shaft (8); and a nut (15) threadedly connected to the screw shaft (14). The nut (15) is capable of moving in an axial direction of the screw shaft (14) to enter between the hollow shaft (8) and the screw shaft (14).
