AI Technical Summary

Benefits of technology

The system effectively stabilizes RVs by reducing rocking, simplifying deployment, and evenly distributing load, thereby minimizing stress on the vehicle's frame and preventing damage.

Problems solved by technology

A recreational vehicle (RV) or trailer tends to rock on its suspension when persons move around inside the vehicle.
This can be time-consuming and inconvenient, particularly in the dark and / or in inclement weather.
Also, known stabilizing systems tend to load the vehicle's frame unevenly and cause it to twist.
Such twisting can place undesirable stresses on the vehicle's body, resulting in leaks and damage to body panels and seams.

Embodiment Construction

[0020]FIGS. 1-5 show an illustrative hydraulically-operated stabilizing system 10 or parts thereof according to the present disclosure. As shown, the system includes four stabilizing jacks 12 that may be installed on an RV, trailer, or other vehicle. (The jacks 12 may be referred to herein individually as the first through fourth jacks 12A-12D or the jacks 12n and collectively as the jacks 12n. Similarly, the various components of the jacks 12n may be referred to herein individually or collectively by appending their respective reference characters in a similar manner.) In other embodiments, the system 10 may include more or fewer than four jacks 12n.

[0021]As best shown in FIGS. 1-3, each jack 12n includes a base 14 configured for attachment to another structure, for example, an RV, a trailer, or another vehicle. The interior of the base 14 defines a channel 16 carrying a trunnion 18. A linear hydraulic actuator 20 is connected to the base 14. As will be discussed further below, th...

Abstract

A stabilizing system includes a plurality of jacks, each operated by a corresponding hydraulic actuator. A hydraulic fluid transfer pump supplies hydraulic fluid to and receives hydraulic fluid from one or more pressure chambers of the actuator. A pilot-operated check or directional valve may be provided in fluid communication with one or more of the pressure chambers and configured to regulate the flow of hydraulic fluid to and from the pressure chamber. A directional control valve may connect the pump output with the jacks via respective pilot-operated directional valves. The directional control valve may include a plurality of switch positions respectively connecting the pump output with pairs of the jacks.
