    摘要： An electrified vehicle, comprising a chassis having a frame, a first tractive element, and a first suspension system coupled with the first tractive element and the chassis. The first suspension system may comprise a first knuckle coupled with the first tractive element, and a first strut-damper coupled with the first knuckle and the chassis, the first strut-damper extending between the chassis and the first knuckle. The first suspension system may also include a first control arm coupled with the first knuckle and the frame member, and a torsion bar coupled with the chassis at a first end of the torsion bar. The torsion bar may extend in a direction substantially parallel with the frame member, where the torsion bar may be configured to support a portion of a mass of the electrified vehicle in response to displacement of the first tractive element relative to the chassis.

    摘要： A vehicle includes a suspension system having a first damper, a second damper, valves and a controller. Each of the first damper and the second damper include a housing and a piston sealingly interfaced with an inner diameter of the housing, dividing the damper into a first and second chamber. Each valve controls flow rate of fluid entering or exiting at least one of the first and second chamber of at least one of the first damper and the second damper. The controller controls the valves to control extension or compression of at least one of the first damper and the second damper based on at least one of a degree of roll of the vehicle during a turn of the vehicle and a degree of pitch of the vehicle during acceleration of the vehicle or a degree of pitch of the vehicle during deceleration of the vehicle.

    摘要： A valve assembly for a suspension system includes a housing having a control port, a first accessory port, and a second accessory port. The housing defines a first flow path extending between the control port and the first accessory port and a second flow path extending between the control port and the second accessory port. The valve assembly also includes a first check valve having a first crack pressure positioned within the housing along the first flow path and a second check valve having a second crack pressure positioned within the housing along the second flow path. A difference between the first crack pressure and the second crack pressure provides a corresponding difference in pressures at the first accessory port and the second accessory port.

    摘要： A suspension element includes a housing, a first joint, and a second joint. The housing is configured to couple a tractive element assembly to a vehicle. The housing has a first end configured to engage a portion of the vehicle and a second end configured to interface with the tractive element assembly. The first joint includes a first actuator and a first resilient member. The first actuator is configured to facilitate linear extension and retraction of the suspension element. The second joint includes a second actuator and a second resilient member. The second actuator is configured to facilitate rotational movement of the suspension element. The first resilient member and the second resilient member are configured to support a static load of the vehicle.

    摘要： A pump system includes a pump assembly and a pump controller. The pump assembly includes a housing defining a first volume and a second volume separated by a divider, a first piston dividing the first volume into a first chamber and a second chamber, a second piston dividing the second volume into a third chamber and a fourth chamber, and a piston rod coupling the first piston and the second piston such that a movement of the first piston causes an equal movement of the second piston. The pump controller is configured to alternately supply a first fluid to the second chamber and the fourth chamber to cause the first piston and the second piston to reciprocate within the housing.

    摘要： A damper assembly for a vehicle suspension system includes a primary damper and a secondary damper. The secondary damper is coupled to the primary damper and includes a housing and an annular piston. The housing includes a sidewall that partially surrounds the primary damper, and the volume between the sidewall and the primary damper defines a damping chamber. The sidewall defines a plurality of apertures. The annular piston is positioned within the damping chamber and slidably coupled to the sidewall. The primary damper provides a base damping force and the secondary damper provides a supplemental damping force that varies based on the position of the annular piston along the housing.
