Document Type and Number:
WIPO Patent Application WO/2020/082320
Kind Code:
A1
Abstract:
Disclosed is an automatic transporter leveling device employing a hydraulic servo for automatically leveling a transporter, such as an automobile, to prevent tipping when the same is negotiating curves at high speeds. The device comprises a hydraulic station, a hydraulic valve (11), a counterweight (9), and a hydraulic cylinder (2). A valve core (7) of the hydraulic valve (11) has one end fixedly connected to a transporter (4) by means of a helical pair (5) and the other end connected to the counterweight (9) by means of a spline pair (8). The invention employs a hydraulic valve (11) to automatically adjust telescopic movement of the hydraulic cylinder (2), thereby preventing vehicles from tipping in various situations with a simple connection structure.
