Title:
HYDRAULIC SUSPENSION APPARATUS HAVING INTEGRAL SUSPENSION FRAMEWORK LATERALLY PRESSED, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/116975
Kind Code:
A1
Abstract:
A hydraulic suspension apparatus having an integral suspension framework laterally pressed, comprising: a suspension framework (2), which is an integral structure and provided with a cavity (20) laterally open; a rubber main spring assembly comprising a main spring inner core (5), a rubber main spring (6), and a main spring base (7), the main spring inner core (5) and the rubber main spring (6) being combined as a whole by a vulcanization process, and the rubber main spring assembly being laterally pressed into the cavity (20) of the suspension framework (2) by means of the main spring base (7); and a support arm (3) embedded in the rubber main spring assembly. According to the hydraulic suspension apparatus, the suspension framework (2) and the rubber main spring assembly are laterally pressed, thereby ensuring the integrity of the suspension framework (2) and the integrity of a liquid chamber; and when the hydraulic suspension apparatus having the integral suspension framework (2) laterally pressed is stressed, the phenomenon of liquid leakage of the liquid chamber due to abnormalities such as breakage of the suspension framework (2) cannot occur, so that the strength and mode of a hydraulic suspension system are higher.
