Embodiment Construction

[0038] The present invention is described in further detail below in conjunction with accompanying drawing and embodiment thereof:

[0039] working principle

[0040] (1) Realization of neutral function

[0041] In order to obtain the control reference, the air spring must have a neutral mechanism to ensure that the vehicle body is at the same height regardless of the load when the vehicle is stationary or running smoothly. When the length of the air spring changes due to pressure changes, the variable-section shaft 9 in the neutral mechanism moves relative to the sleeve 8. At a certain position, the neutral air intake switch 6 and the neutral air discharge switch 7 are both in the closed state. At this time, the air spring The chamber neither intakes nor exhausts air, which is the neutral position (see image 3 ). When the load of the vehicle increases, the load on the spring increases accordingly, its length becomes shorter, and the vehicle body is lower than the neutral...

Abstract

The invention discloses a mechanical vehicle active suspension device, which overcomes the defects that a device adopting an electronic technology has a control system costing 3,000 dollars and the maintenance cost is high in the prior art. The device is characterized in that: a diaphragm (C) is arranged between a reference chamber (A) and an air spring auxiliary chamber (B) with an inertia switch (5) through a pipeline; and the reference chamber (A), the air spring auxiliary chamber (B) and an air spring main chamber (D) are connected through a pipeline. The mechanical vehicle active suspension device has the advantages that: the diaphragm (C) takes pressure difference of the two chambers as a control signal and driving power to automatically adjust the suspension rigidity in a mechanical mode; the inertia switch (5) can instantaneously change the suspension rigidity, cut off a control switch and solve the contradiction of operability and comfortableness; a hole on a ball (16) realizes the cut-off function in any direction; the pipeline connection is skillful, complicated and unique, so that the functions are realized and are not interfered mutually; a complicated process does not exist, the device is easy to promote and apply, and great reformation of the vehicle suspension device is provided; and the device is used for vehicle suspension.

Description

technical field [0001] The invention is a vehicle suspension device in the international patent classification transportation and general vehicles, in particular a mechanical vehicle active suspension device. Background technique [0002] The purpose of the vehicle suspension device in the prior art is to form a vibration damping and buffering effect between the wheel and the vehicle compartment, so as to increase the comfort, reduce vibration and reduce noise during vehicle operation. Its structure is that a spring or a damping steel plate is placed between the wheel and the compartment. This structure has a certain effect on increasing the comfort of the vehicle during driving and reducing vibration and noise. [0003] The active suspension system in the prior art is also supported by sensors and electronic technology. Multiple sensors collect signals such as acceleration, speed, and position, and transmit them to the control unit, which then performs calculations and sen...
