Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of the limitation of the layout of the central steering plate and the problem of weakening the strength of the longitudinal beam when passing through the central longitudinal beam. It provides a segmented sun gear steering plate, which can be bypassed by gear transmission. The central longitudinal beam is arranged to avoid changing the central longitudinal beam to weaken its strength, and at the same time enhance the flexibility and diversity of the steering plate arrangement

Embodiment 1

[0024] to combine Figure 4 , 5 And 6, as shown in the figure, the multi-axis hydraulic module combination trailer segmented sun gear steering plate of the present invention can be divided into the sun gear 701 and the planetary parts on the left and right sides. The planetary parts include side gears 7021, connecting shafts 7022, The fixing seat 7023 and the side plate 7024. The sun gear 701 can be installed above or below the central longitudinal beam according to specific vehicle models and conditions, and the present invention will be described by taking the installation above as an example. The two side gears 7021 are distributed on the left and right sides of the sun gear 701 and mesh with them; the connecting shaft 7022 is also used as the gear shaft of the side gear 7021 to link with the gear; the four fixing seats 7023 are welded on the left and right webs of the central longitudinal beam 4, It is used to fix the connecting shaft 7022 and make it freely rotate in th...

Embodiment 2

[0027] to combine Figure 7 The difference between embodiment 2 and embodiment 1 is that embodiment 1 has only one side plate 7024, and the hydraulic steering cylinder 6, the first steering rod 1 and the second steering rod 2 are all installed on the side plate 7024; Embodiment 2 has two side plates 7024a and 7024b, the steering rod is installed on the side plate 7024a, and the hydraulic steering oil cylinder is installed on the side plate 7024b. This embodiment is applicable to the situation that the steering rod and the hydraulic steering cylinder cannot be installed on the same plane, and according to the actual situation, an embodiment of three side plates can also be evolved.

Embodiment 3

[0029] to combine Figure 8 The difference between embodiment 3 and embodiment 1 and embodiment 2 is that: the side plate 7024 and the side gear 7021 of embodiment 1 and embodiment 2 are two separate parts; the side plate and the side gear of embodiment 3 are combined Together into one part 7025. This embodiment is applicable to the situation where the sun gear and the side plate can be arranged on one plane.

Abstract

The invention relates to a segmental type sun gear steering plate of a multi-axis hydraulic module combination trailer. The plate comprises a central gear (sun gear) and planet pieces at the left and right sides. The sun gear is a straight toothed cylindrical gear and installed on the transverse centre of a wing plate above or below a central longitudinal beam. The planet piece comprises side gears, a side plate, a connection shaft and a fixed base. The side gears are straight toothed cylindrical gears. The side gears are arranged at the left and right sides of the sun gear and meshed with the sun gear. The two side gears are completely same in shapes and parameters. The connection shaft is fixed on a web plate of the central longitudinal beam through the fixed base and can freely rotate in the axial hole of the fixed base. The connection shaft is simultaneously used as the gear shaft to be matched with the axial hole of the side gear. The connection shaft and the side gear can synchronously rotate without freedom degree. The connection shaft and the side plate are fixedly connected together without freedom degree. One end of the side plate and the connection shaft are connected into a whole. The other end of the side plate, like the original central steering plate, is connected to a steering hydraulic oil cylinder and a steering pull rod. The central longitudinal beam is prevented from being changed. The steering plate is flexible and variable in arrangement.

Description

technical field [0001] The invention relates to a steering plate, in particular to a steering plate of a multi-axis hydraulic module combination trailer. Background technique [0002] Heavy-duty multi-axle vehicles have special working sites and large limitations. They usually carry long and heavy parts. Therefore, there are many axles, the size of the vehicle is large, and it is generally in a low-speed operation state. The steering system usually used in this kind of vehicle is composed of tie rod assembly, coordination mechanism, steering knuckle plate and steering hydraulic cylinder. The left and right wheels are controlled by hydraulic cylinders, which can realize steering in the form of figure-eight steering and crab steering. When the vehicle is turning, the inner wheel is forced to travel along an arc with a smaller radius of curvature than the outer wheel, so the control cylinders of the left and right wheels need to be coordinated and controlled by the coordination...
