Large-rotating-angle wet brake steering axle

Abstract

The invention discloses a large-rotating-angle wet brake steering axle. The Large-rotating-angle wet brake steering axle comprises an axle body, steering knuckles, main pins, hubs, wet brakes, a tie rod and a steering oil cylinder. The two ends of the axle body are connected with the hubs and the steering knuckles through the main pins correspondingly. By rotating a steering wheel, oil is injectedinto the oil cylinder through an oil pipe connected with the steering oil cylinder, thus, a piston of the steering oil cylinder is pushed to move in the left-and-right direction, a piston rod is driven to move, the tie bar is connected with the two steering knuckles, the piston rod moves to drive the steering knuckles to rotate, thus, the hubs rotate, the hubs are acted through the wet brakes forbraking, guarantees can be achieved in different harsh environments, at the same time, the requirements of the smaller steering structure and the larger steering angle are met, the wet brakes are used for replacing original drum brakes or clamp brakes, a vehicle has stable and good braking performance in different use environments, the structural layout is smaller and more compact, and the performance requirement of the large rotating angle can be met.

Description

technical field [0001] The invention relates to the field of automobiles and vehicles, in particular to a large-angle wet brake steering axle. Background technique [0002] The steering axle refers to the axle that undertakes the steering task; the front axle of a general car is a steering axle, and the front and rear axles of a four-wheel steering car are all steering axles. It uses the steering knuckle in the axle to deflect the wheels at both ends by a certain angle. , in order to realize the steering of the car, it not only bears the vertical load of the car, but also bears the longitudinal force and lateral force and the moments caused by these forces. [0003] Airports, ports, and large ships have small operating spaces, and have strict requirements on the turning radius of the vehicle, and have strict requirements on the braking performance of the vehicle. The existing steering axle has a small turning angle, and the overall vehicle structure is bloated and The braki...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a large-angle wet brake steering axle, in order to overcome the small operating space of the above-mentioned airports, ports and large ships, and the strict requirements on the turning radius of the vehicle and the strict requirements on the braking performance of the vehicle. The required use environment, the existing steering axle has a small turning angle, and the overall vehicle structure is bloated and the braking performance is poor, which cannot meet the technical problems of heavy tractors or self-driving industrial vehicles used in the above-mentioned environment
