Suspension and leveling system for a vehicle

The suspension system of the present invention includes an elongated spring having one end attached to the vehicle frame and having a second end. A pneumatic bag includes an upper end which is attached to the vehicle frame and a lower end. A securing bracket attaches the lower end of the bag and the second end of the elongated spring to the axle so that the weight of the vehicle frame above the axle is supported in combination by the spring and the air bag. A pneumatic control system is in communication with the bag for selectively introducing air to the bag so as to control the pressure within the bag and thereby control the height that the bag supports the vehicle frame above the axle. A stabilizer bar is pivotally connected at one end to the vehicle frame and at the other end to the axle so as to cause the vehicle frame to be centered over the axle while at the same time permitting the vehicle frame to move vertically with respect to the axle. The control means includes both manual and automatic control valves for controlling the height of the frame above the axle. Electrical switches are connected to solenoids for controlling the valves so as to permit the raising and lowering of the vehicle frame with respect to the axle.

Air spring having internal sealing band and method of installing same

ABSTRACT OF THE DISCLOSURE An air spring for motor vehicles including first and second end members, at least one of which is a piston, with an intervening flexible sleeve forming a fluid pressure chamber therebetween sealingly connected to the end members. A continuous annular sealing band clamps at least one end of the flexible sleeve within an annular recess formed on the inside surface of an annular wall portion of one of the end members within an open end of the end member by compressing the sleeve material between the band and wall, and without deforming the band or wall of the end member beyond their elastic limits. In one embodiment, the annular wall of the end member is formed of plastic and is deformed outwardly but maintained within its elastic limits upon insertion of the band within the open end. The end of the sleeve is rolled over the sealing band and then the sleeve end and band are inserted by a press plate into the open end of the end member with the band compressing and sealing the flexible material of the sleeve into the annular recess. The compressed flexible material expands to seal the sleeve against the end member. In another embodiment, the press plate expands the plastic material of the end member outwardly upon inserting the band and a rolled end of the flexible sleeve into the annular recess of the annular wall portion whereupon the wall attempting to return to its unstressed state seals the flexible sleeve between the sidewall and band.
