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 conne

Example Embodiment

[0024] Examples:

[0025] Such as Figure 1-3 Shown: a vehicle chassis suspension vibration damping and locking integrated device, which mainly includes a piston rod 18 and a cylinder tube 4, a piston 20, a deadlock valve 23, a DC electromagnet 5, an oil storage tank 16, and the like. The end cover of the lower end of the cylinder tube 4 is fixedly connected to the adapter 1 with lifting lugs through the bushing 2 and the pin 3, and the lifting lugs are fixed on the axle through the pin and the pin. The piston 20 of the piston rod 18 and the piston 18 separate the inner cavity of the cylinder 4 into two mutually incommunicable upper and lower cavities. A guide seat 12 is installed on the top of the cylinder tube 4, and the guide seat 12 is tightly connected with the cylinder tube 4 through threads. Sealing rings are provided between the guide seat 12 and the cylinder tube 4, and the guide seat 12 and the piston rod 18 respectively. Prevent oil leakage during work. A dust-proof seal...

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...
