Abstract
An annular bellows unit for replacing a vehicle suspension coil spring that encloses a shock absorber or hydraulic actuator includes annular second flange members that are sealingly connected at opposite ends of respective inner and outer bellows members to form a closed chamber, and a fill port in one of the flange members for pressurizing the chamber.
Claims14
An annular bellows unit for converting a vehicle suspension having a coil spring enclosing a telescopic element, the bellows unit comprising:
- (a) an outer bellows having first and second ends;
- (b) an annular first flange member sealingly connected at the first end of the outer bellows;
- (c) an annular second flange member sealingly connected at the second end of the outer bellows;
- (d) an inner bellows sealingly connected between the first and second flange members within the outer bellows member, a closed chamber being formed between the outer and inner bellows;
- and
- (e) a fill passage extending through the second flange member in fluid communication with the chamber and having a fill port for pressurizing the chamber.

An annular bellows unit for converting a vehicle suspension having a coil spring enclosing a telescopic element, the bellows unit comprising:
- (a) annular first and second flange members, the first and second flange members each comprising an outer flange and an axially separable inner flange;
- (b) an inner bellows comprising:
- (i) a plurality of bellows segments, each of the bellows segments having facing tapered elements joined at outer peripheral extremities thereof, adjacent segments being joined between facing inner peripheral extremities of adjacent elements, the inner bellows further comprising a plurality of outside reinforcing rings, each of the outside reinforcing rings being connected proximate the facing outer peripheral extremities of a respective bellows segment;
- and
- (ii) first and second outwardly projecting bellows flange portions being formed on respective opposite ends of the inner bellows;
- (c) a plurality of clamp fasteners for sealingly clamping the inner and outer flange portions of the first and second flanges on opposite sides of respective ones of the bellows flange portions of the inner bellows;
- (d) an outer bellows having axially extending tubular end portions, the end portions enclosing respective portions of corresponding ones of the first and second flange members;
- (e) first and second outer clamp rings on respective end portions of the outer bellows for sealingly connecting the outer bellows to the first and second flange members, a closed chamber being formed between the outer and inner bellows;
- and
- (f) a fill passage extending through the second flange member in fluid communication with the chamber and having a fill port for pressurizing the chamber.
