Front axle steering oil tank assembly and steering system

Abstract

The invention provides a front axle steering oil tank assembly. The assembly comprises a steering oil tank and an oil tank support, and the steering oil tank is fixed to a vehicle body through the oiltank support and provided with two oil way connectors which include an oil outlet and an oil return port. The oil outlet is connected with an oil inlet of a steering pump, and the oil return port isconnected with an oil return port T of a hydraulic power steering gear assembly and a second connector of a rear axle steering integrated valve set. By means of the front axle steering oil tank assembly and the steering system thereof, closed-loop control over steering hydraulic cylinder and steering wheel operation and unlocking and locking control over a steering axle passive active aligning andrigid locking device can be achieved.

Description

[0001] This application is a divisional application for April 22, 2019, application number 2019103219846, and the title of the invention "a rear axle steering integrated valve group and steering device". technical field [0002] The patent of the invention relates to a high-reliability electromechanical-hydraulic all-wheel steering system suitable for wheeled vehicles, which belongs to the fields of mechanical, hydraulic and motor vehicle applications. Background technique [0003] Wheeled equipment is an important part of the army's weapon equipment system, and it is an important land mobile platform for the land, sea and air forces to realize the development strategy of "global mobility, three-dimensional protection, multi-dimensional and multi-energy". Vehicle mobility, broadly speaking, refers to the ability to quickly reach space and regions, including tactical mobility and strategic / combat mobility. For wheeled vehicles, the improvement of mobility is more focused on im...

Problems solved by technology

[0005] (2) Compared with engineering vehicles, wheeled vehicles have more complex working conditions and harsher environments. The response characteristics and impact resistance of the follow-up steering axle are common issues that affect vehicle handling stability and safety.

[0007] From the above comparison, the variable vehicle structure, complex application environment, and harsh service conditions of wheeled vehicles have brought great challenges to the reliable application of all-wheel steering technology on wheeled vehicles. The technical framework of the all-wheel steering system of engineering vehicles cannot meet the requirements of use. Therefore, it can simultaneously have the dynamic response and impact resistance of the follow-up steering axle in complex environments, and the median steering stiffness of the follow-up steering axle under nonlinear loads and The all-wheel steering system with the three core capabilities of the active return of the follow-up steering axle under the condition of system failure and vehicle damage will become a high-reliability all-wheel steering system suitable for wheeled vehicles
