Abstract
A modular telescopic front fork assembly which is adaptable to a wide range of applications is disclosed. The modular telescopic front fork assembly is utilized for a front of a vehicle having at least one front wheel. The modular telescopic front fork assembly includes a removable self-contained damper cartridge. This removable self-contained damper cartridge includes a housing and a reciprocating piston rod axially extending from the housing. A first securing mechanism steerably secures the housing of the self-contained damper cartridge to the front of the vehicle. A second securing mechanism secures the piston rod of the self-contained damper cartridge adjacent to the front wheel of the vehicle. This provides a removable self-contained damper cartridge which damps the movement of the front wheel relative to the vehicle.
Claims19
A modular telescopic front fork assembly for a front of a vehicle having at least one front wheel, said modular telescopic front fork assembly comprising:
- a removable self-contained damper having a housing and a reciprocating piston rod axially extending from said housing;
- a suspension spring positioned about said reciprocating piston rod;
- an adjustable spring seat assembly having an upper spring seat and a lower spring seat each having step portions operable to permit multiple spring preload adjustments;
- a first securing mechanism operable to removably and steerably secure said housing of said removable self-contained damper to the front of the vehicle;
- a second securing mechanism operable to removably secure one end of said piston rod of said removable self-contained damper adjacent to the front wheel of the vehicle;
- and
- a cover operable to cover at least a portion of said housing, said cover and lower spring seat operable to be rotated to adjust said suspension spring preload, wherein said removable self-contained damper is operable to damp the relative movement of the front wheel relative to the vehicle and is operable to be readily replaced to meet a wide range of applications.
A modular telescopic front fork assembly for a front of a vehicle having at least one front wheel, said modular telescopic front fork assembly comprising:
- a removable self-contained damper having a housing and a reciprocating piston rod axially extending from said housing;
- a first securing mechanism operable to removably and steerably secure said housing of said removable self-contained damper to the front of the vehicle, said first securing mechanism including a first triple clamp having a first cylindrical relief for removably clamping a first cover and a second cylindrical relief for rotatably retaining a second cover, said first and second covers covering said housing of said removable self-contained damper;
- and
- a second securing mechanism operable to removably secure one end of said piston rod of said removable self-contained damper adjacent to the front wheel of the vehicle, wherein said removable self-contained damper damps the relative movement of the front wheel relative to the vehicle and can be readily replaced to meet a wide range of applications.
A modular telescopic front fork assembly for a front wheel of a motorcycle, said modular telescopic front fork assembly comprising:
- a replaceable damper cartridge having a housing and a reciprocating piston rod axially extending from said housing;
- a clamp operable to be steerably secured to the motorcycle and removably securing said housing of said replaceable damper cartridge;
- a first cover and a second cover, said first and second covers covering said housing of said replaceable damper cartridge and retained by a first and a second relief in said clamp;
- and
- a slider having a wall defining a chamber and a bore, said chamber operable to receive a portion of said housing and a portion of said piston rod and said bore operable to removably receive and secure one end of said piston rod adjacent to the front wheel, wherein said replaceable damper cartridge is removably secured in an inverted position and operable to damp the relative movement of the front wheel relative to the motorcycle.
A modular telescopic front fork assembly for a front wheel of a motorcycle having a first triple clamp and a second triple clamp, said modular telescopic front fork assembly comprising:
- a first removable strut cartridge having a first housing and a first reciprocating piston rod axially extending from said first housing, said first housing of said first removable strut cartridge operable to be clampingly received within the first and second triple clamps;
- a first cover and a first spring, said first spring being positioned about said first reciprocating piston rod and said first cover operable to be rotated to adjust a first spring preload of said first spring;
- a second removable strut cartridge having a second housing and a second reciprocating piston rod axially extending from said second housing, said second housing of said second removable strut cartridge operable to be clampingly received within the first and second triple clamps;
- a second cover and a second spring, said second spring being positioned about said second reciprocating piston rod and said second cover operable to be rotated to adjust a second spring preload of said second spring;
- a first mounting member having a first bore which receives one end of said first piston rod and operable to removably secure said one end of said first piston rod adjacent to the front wheel;
- and
- a second mounting member having a second bore which receives one end of said second piston rod and operable to removably secure said one end of said second piston rod adjacent to the front wheel, wherein said first and second removable self-contained strut cartridges are operable to damp the relative movement of the front wheel relative to the motorcycle.
A method for assembling a modular telescopic front fork assembly for a front wheel of a motorcycle having a first triple clamp and a second triple clamp, said method comprising the steps of:
- slidably inserting into said first and second triple clamps in an inverted position, a first removable self-contained damper having a first housing and a first reciprocating piston rod extending from said first housing;
- clampingly securing said first housing of said first removable self-contained damper within said first and second triple clamps;
- slidably inserting into said first and second triple clamps in an inverted position, a second removable self-contained damper having a second housing and a second reciprocating piston rod extending from said second housing;
- clampingly securing said second housing of said second removable self-contained damper within said first and second triple clamps;
- removably securing one end of said first piston rod adjacent to the front wheel;
- removably securing one end of said second piston rod adjacent to the front wheel;
- positioning a first suspention spring about said first reciprocating piston rod and a second suspension spring about said second reciprocating Piston rod;
- and
- adjusting a spring preload of said first and second suspension springs by rotating a first cover positioned about a portion of said first housing and rotating a second cover positioned about a portion of said second housing, wherein said first and second removable self-contained dampers damp the movement of the front wheel relative to the motorcycle and can be readily replaced upon wear.
