Vehicle suspension systems |
摘要 |
A suspension system for a vehicle includes a damper and a jack assembly. The damper includes a first tube defining a first cavity and having a longitudinal axis, a second tube disposed within the first cavity and defining a second cavity, wherein the second tube is spaced apart from the first tube to define a reservoir chamber, and a piston translatable within the second cavity along the axis, wherein the piston abuts the second tube to define a rebound chamber and a compression chamber. The system includes a jack assembly attached to the damper and configured for raising and lowering the body with respect to the wheel. The assembly includes a jack piston abutting the first tube, and a jack cylinder also abutting the first tube and translatable with respect to the jack piston to thereby raise and lower the body. A vehicle including the suspension system is also disclosed. |

1. A suspension system for a vehicle, the suspension system comprising:
a damper including:
a first end attachable to a body of the vehicle;a second end spaced apart from the first end and attachable to a wheel of the vehicle;a first tube defining a first cavity therein and having a central longitudinal axis;a second tube disposed within the first cavity and defining a second cavity therein, wherein the second tube is spaced apart from the first tube to define a reservoir chamber therebetween; anda piston translatable within the second cavity along the central longitudinal axis, wherein the piston sealingly abuts the second tube to define a rebound chamber at the first end and a compression chamber at the second end; a jack assembly attached to the damper and configured for raising and lowering the body of the vehicle with respect to the wheel, wherein the jack assembly includes:
a jack piston abutting the first tube; anda jack cylinder abutting the first tube and translatable with respect to the jack piston to thereby raise and lower the body of the vehicle;wherein the jack piston and the jack cylinder define a jack chamber therebetween at the first end; a fluid flowable between the rebound chamber, the reservoir chamber, and the jack chamber; a fluid connection element disposed between the first tube and the second tube and configured for fluidly connecting the rebound chamber with the jack chamber; a first control valve disposed in fluid communication with the jack chamber and the rebound chamber; a first check valve disposed between and in fluid communication with the first control valve and the jack chamber; a second control valve disposed in fluid communication with the jack chamber and the reservoir chamber; and a second check valve disposed between and in fluid communication with the second control valve and the reservoir chamber; wherein each of the first control valve, the first check valve, the second control valve, and the second check valve is transitionable between an open position and a closed position. |
