Passive hydraulic rigid locking system of vehicle flexible suspension

Through the passive hydraulic rigid locking system, the flexible to rigid conversion of the vehicle suspension is achieved by using a double-acting single piston rod hydraulic cylinder and an electromagnetic hydraulic seat valve, which solves the problems of complex system, high energy consumption and high cost in the existing technology. Provides solutions with simple composition, simple control and low energy consumption.

Abstract

The invention relates to a passive hydraulic rigid locking system of a vehicle flexible suspension. The passive hydraulic rigid locking system comprises a hydraulic cylinder, a locking valve device, a frame, a spring suspension and an axle. A spring suspension is arranged between the frame and the axle, and a frame hinge point is arranged at the cylinder rod end of the hydraulic cylinder and the cylinder rod end of the locking valve device and hinged to the frame. The cylinder body end of the hydraulic cylinder and the lock-up valve device is provided with an axle hinge point and is hinged to an axle; the passive hydraulic rigid locking system of the vehicle flexible suspension has the remarkable advantages that in the aspect of composition, elements such as a hydraulic pump, a reversing valve and pipeline accessories are omitted, and the number of elements is small; in the control aspect, only the electromagnetic hydraulic locking valve needs to be controlled to be opened or closed, and control is simple; in the aspect of energy consumption, a prime motor does not need to output energy in the locking working process, and the energy consumption is low; in the aspect of cost, hydraulic elements are few, energy consumption is low during use, and cost is low.
