Gate-type axle assembly

Abstract

The invention provides a gate-type axle assembly. Wheels can be steered synchronously, the distance from a bridge to the ground is large, and the gate-type axle assembly can adapt to various construction environments, has high versatility, can be compatible with the installation of multiple components, and reduces vehicles on the construction site. According to the technical scheme, the gate-typeaxle assembly comprises a horizontally arranged bridge and wheel assemblies installed at both ends of the bridge. Each wheel assembly comprises wheels, a motor for driving the wheels, and a bracket. The lower end of the bracket is connected to the wheel axle, and the upper end of the bracket is connected to the bridge end.

Description

technical field [0001] The invention relates to a vehicle axle for engineering vehicles, in particular to a portal type vehicle axle assembly. Background technique [0002] At present, there is a great demand for various engineering vehicles at home and abroad. The steering system of many engineering vehicle chassis requires front and rear four-wheel steering. The existing engineering vehicles are not very ideal in the design of the four-wheel steering system. The main defect lies in the four-wheel steering. When the turning angle is inconsistent and the walking speed is slow, the front and rear tires are not on the same track when the driving speed is fast, which hinders the development of engineering vehicles. [0003] In the process of infrastructure construction such as roads, railways, and agriculture, it is often encountered that there are no roads or sites with poor traffic conditions. The existing engineering vehicles have low chassis or too wide bridges to enter suc...

[0002] At present, there is a great demand for various engineering vehicles at home and abroad. The steering system of many engineering vehicle chassis requires front and rear four-wheel steering. The existing engineering vehicles are not very ideal in the design of the four-wheel steering system. The main defect lies in the four-wheel steering. The corners are inconsistent and the walking speed is slow. When the driving speed is fast, the front and rear tires are not on the same track, which hinders the development of engineering vehicles.

[0003] In the process of infrastructure construction such as roads, railways, and agriculture, we often encounter sites with no roads or poor traffic conditions. Existing engineering vehicles have low chassis or too wide bridges to enter such sites for construction.

And, the existing engineering vehicles are poor in versatility. One engineering vehicle can only be equipped with one type of attachment, and the construction site has a small space and a lot of debris, which makes it impossible to operate smoothly, which greatly hinders the progress of the project.
