Abstract:
A damper with a vehicle height adjusting function comprising a cylindrical case (12) vertically movably installed outside the damper body (1) of an inverted damper and connected to a damper rod (2), a pressure chamber (13) defined between the damper body (1) and the case (12) and having sealed therein a pressure medium having a low boiling point to undergo gas-liquid change, a heater disposed in the pressure chamber (13) for heating and vaporizing the pressure medium to raise the vehicle height by the vapor pressure of the pressure medium, wherein the heater is adapted for easy mounting and dismounting to improve the maintainability and the effect of the presence of the heater on the suspension stroke is reduced. The heater is formed in a bar shape, and this bar heater (16) is inserted horizontally into the bottom of the pressure chamber (13) through a mouth ring (12d) installed in the case (12), the tail end of the bar heater (16) being threadedly connected to the mouth ring (12d).
Abstract:
A suspension system can include an air spring, an air reservoir external to the air spring, and a flow control device which variably restricts flow of air between the air spring and the air reservoir. Flow between the air spring and the air reservoir may be permitted in response to compliance of the suspension system, and the air spring can have an internal air volume at least 2½ times as great as a volume of the air reservoir. The flow control device may permit flow between the air spring and the air reservoir in response to a predetermined pressure differential level across the flow control device. Multiple air reservoirs can be internal to an axle, and can be isolated from each other in the axle.
Abstract:
An air suspension system includes an air spring having an air cell and a piston. Preferably, the air cell tightly conforms to the piston and has a frustro-conical tapered configuration. By providing a tight conformal fit between the piston and the air cell, and by expanding the diameter of the air cell therefrom, the likelihood that the air cell will invert is substantially decreased. Similarly, when the air cell is deflated the taper facilitates the air cell obtaining the original rolled or deflated position. In another embodiment, the damper slows the extension of the longitudinal member to provide more time for an anti-vacuum system to equalize the pressure within the air cell.
Abstract:
A vehicle suspension includes a mount assembly for a gas strut. The mount system includes a resilient bushing supported upon an annular carrier. A rigid annular member is mounted within an inner diameter of the resilient bushing. The resilient bushing, the annular carrier, and the annular member are symmetrical about an equator. The resilient bushing, the annular carrier, and the annular member are of a two-piece structure which are mirror images when reflected through the equator. The two-piece structure allows rapid assembly, simplification of manufacture, and assembly into the vehicle structure. Another mount system includes a one-piece resilient bushing having a cylindrical annular carrier.
Abstract:
A vehicle has a novel frame structure that comprises two novel frame rails that extend parallel to the longitudinal axis of the vehicle and cross-members that are fixedly engaged between the two novel frame rails. Each of the novel frame rails comprises a web that extends vertically along the length of the frame rail, an upper flange that extends horizontally from an upper end of the web, and a lower flange that extends horizontally from a lower end of the web. Each of the novel frame rails further comprises one or more reinforcing lips, each of which extends vertically from an outer end of either the upper flange or the lower flange.
Abstract:
A vehicle frame includes a space frame assembly which is mounted to a pair of longitudinal mainframes. The space frame assembly includes a multiple of interconnected supports, which are configured to support a plurality of vehicle components.
Abstract:
A grease fitting adapter for lubricating a Hendrickson suspension of a vehicle. The adapter includes a bracket and a hose connected to the bracket. The hose has a first end with a fitting thereon to cooperate with a fitting in the Hendrickson suspension. The hose has a second end with a fitting thereon to receive the lubricant from a source of lubricant. The adapter is mounted on the Hendrickson suspension by a fastener connected to the bracket and is mounted such that the lubricant is introduced from the outer side of the vehicle. A retrofit kit and a method of lubricating the Hendrickson suspension is disclosed.
Abstract:
A MacPherson strut front suspension is provided with an upper spring seat assembly which retains the upper end of a front coil spring and is rotatable together with the coil spring and a strut outer tube relative to a vehicle body. The upper spring seat assembly comprises concentric inner and outer tubular members, a spring seat rubber interconnecting the inner and outer tubular members, and a shallow dish-shaped abutment member which is attached to the inner tubular member to be rotatable together therewith and abuttingly engageable to limit upward movement of the outer tubular member relative to the inner tubular member.
Abstract:
The invention relates to an arrangement for displacing a tiltable cab unit (11) between a lowered and a raised position relative to a vehicle frame (16), the arrangement comprising a fluid actuator mounted between the vehicle frame (16) and the cab unit (11 ), which fluid actuator (17) is arranged to displace the cab unit (11) between the lowered and raised positions, and an elongated conduit bundle (20) comprising at least one media conduit (23, 24, 25) having a first section (23; 31; 41; 51; 71) which is connectable to the vehicle frame (16), a second section (24; 32; 42; 52; 62) which is connectable to the cab unit (11), and a third section (25; 33; 43; 53; 63) which is fitted between the above-mentioned first and second sections (23; 31; 41; 51; 71, 24; 32; 42; 52; 62). At least one conduit making up a third section (25; 33; 43; 53; 63) of the media conduit (23, 24, 25) is arranged in or on the fluid actuator (17; 30; 40; 50; 60).
