Vibration-damping and locking integrating device of chassis suspension fork of vehicle

Abstract

The invention relates to a vibration-damping and locking integrating device of a chassis suspension fork of a vehicle, in particular to a vibration-damping and locking device of a chassis suspension fork of a vehicle. The vibration-damping and locking device mainly comprises a piston rod, a cylinder, a piston, a lock valve, a DC electromagnet, an oil tank, and the like. The device is arranged between a vehicle body and an axle, has the characteristics of compact structure, less space occupation, convenient installation, high sensitivity and reliability, low cost, and the like, can complete the bilateral rigid locking and vibration damping of the chassis suspension fork of a vehicle and can adapt to the severe atmosphere of a vehicle chassis. The device can be widely used as a vibration-damping and locking device of the chassis suspension forks of various vehicles, is suitable for vehicles with compact structural space, and particularly suitable for being used as the vibration-damping and locking devices of the chassis suspension forks of special vehicles, special purpose vehicles and heavy-duty vehicles, thereby satisfying the special use requirements of the vehicles.

Description

1. Technical field [0001] The invention belongs to the technical field of vehicle chassis suspension structures, and in particular relates to a vibration damping and locking device for vehicle chassis suspensions. 2. Background technology [0002] As a system to support the body and improve ride comfort, the automobile suspension system plays an important role in the chassis structure of the automobile. In order to prevent the vehicle suspension from bouncing, realizing the two-way rigid self-locking of the chassis suspension will increase the use requirements of the vehicle. In some special vehicles and special vehicles, such as wheeled cranes, aerial work vehicles, etc., under some working conditions, it is necessary to realize the two-way rigid self-locking of the chassis suspension. Except for the oil-pneumatic suspension system, other types of suspension systems are difficult. With this two-way self-locking function. However, the use of oil-pneumatic suspension to rea...

AI Technical Summary

Problems solved by technology

The main disadvantages of this device are: 1. It is an auxiliary mechanical locking device that is increased by means of the existing shock absorber function. 2. The device needs to be combined with the existing shock absorber of the vehicle to realize the locking action, and the inner cavity of the cylinder barrel of the existing shock absorber is fixed on the piston rod. The piston is divided into upper and lower chambers, and the upper and lower chambers of the cylinder are connected through the expansion valve and the flow valve installed in the piston on both sides of the piston rod, and the upper and lower chambers of the cylinder are connected only by the friction force of the brake band, and then As a result, the locking mechanism cannot realize the two-way rigid locking of the vehicle chassis suspension under heavy load and high pressure conditions; 3. The locking device itself does not have the function of vibration reduction, and cannot work independently from the original shock absorber at all; 4. .Only limited to vehicles with air actuators, and only limited to parking brake conditions, the scope of application is limited, and the locking ability generated by air actuators is limited; 5. The shock absorber is separated from the locking device, Take up a lot of chassis space
