A suspension device of a bicycle front fork is installed in a head tube of a bicycle handlebar. The suspension device includes: a cylinder with a bottom fixed to a base of the bicycle front fork and a top passed into the head tube; a piston rod with a top fixed to an inner wall of the head tube and a bottom having a piston and extended into the cylinder; a spring device coupled to the piston rod and having a force to push the piston rod away from the cylinder. The cylinder below the piston has an air chamber communicated with an intake valve of the base. The air pressure of air chamber may be adjusted to adjust the buffering pressure of the spring device, so that a user may adjust the shocking pressure of the front fork.

Adjustable suspension comprising a suspension body having a bottom, a piston disposed in the suspension body and comprising a piston head, the bottom and the piston head delimiting a main chamber inside said suspension body, the piston being movable in translation in the suspension body; and a fluid distribution device comprising a main fluid inlet configured to inject a fluid into the suspension and a fluid outlet, the piston being able to assume a first position in which the fluid distribution device is configured to bring the fluid injected through the main fluid inlet into the main chamber so as to deploy the piston and a second position in which the fluid distribution device is configured to guide the fluid injected through the main fluid inlet to the fluid outlet in order to evacuate the fluid out of the suspension.

A user accessible shock travel spacer assembly is disclosed herein. The system is used on a shock assembly having a shaft with an initial predefined stroke length. A retaining cap having a retaining cap thickness and a retaining cap opening therethrough. The retaining cap opening having a diameter that is larger than an outer diameter (OD) of a shaft of a shock assembly. At least one fastener to fasten the retaining cap with a portion of the shock assembly about the shaft, such that the retaining cap reduces a stroke length of the shaft of the shock assembly by the retaining cap thickness.

An accumulator defines an accumulator volume that can be placed into communication with a spring chamber of a gas spring. A working volume of the gas spring is the sum of the spring chamber volume and the accumulator volume. The accumulator can be configured so that the accumulator volume can be selectively increased or decreased as desired, thus modifying performance of the associated gas spring.

A wheel with a suspension system being connectable to a vehicle, like a wheel chair, comprises a hub (38) and a rim (34) rotatable about the axle (42) of the hub (38). Between the hub (38) and the rim (34), a number of support members (40) is located. The support members (40) are adapted to retain the distance when stressed up to a threshold value and recoverly alter the distanced when stressed over this threshold value. According to the invention, the support members (40) are comprising spring elements (50), damping strokes by compression if the support member (40) is compressed or elongated. The spring elements (50) are preferably preloaded.

A method for pressurizing and depressurizing a shock absorber of an aircraft. More specifically, it relates to a method in which an aircraft weight and ambient temperature are used to calculate a required pressurization level of a shock absorber. As such, the shock absorber may be pressurized to the correct level without applying an iterative approach, greatly reducing initialization time.

An air chamber, an air spring, an air suspension system, and a vehicle are provided. The air chamber is configured to communicate with a main cavity of the air spring (10). The air chamber includes a housing (21). The housing (21) has a first cavity (211), a plurality of second cavities (212), and a plurality of first breather holes (216). Each second cavity (212) communicates with the first cavity (211) through one first vent hole (216). The first cavity (211) is configured to communicate with the main cavity (31), and is configured to fit with a movable piece (22), so that N second cavities (212) communicate with the main cavity (31), where N is a natural number.

The embodiment of the present application provides a balance mechanism and a mounting bracket. Wherein, the balance mechanism includes: a mounting part; a sliding part, which is slidably connected to the mounting part; a spring, the first end of the spring is fixed to the sliding part; an adjuster, which has a third end and a fourth end opposite to the third end, wherein the third end is connected to the mounting part, and the fourth end is connected to the second end of the spring. The adjuster is configured to adjust the spring, so as to stretch and compress the spring. The embodiments of the present application can reduce the cost of the balance mechanism and thereby reduce the cost of the mounting bracket.
