technical field

The utility model relates to the technical field of harvesting machinery, in particular to a steering bridge assembly for a large corn machine.

Background technique

At present, when the large-scale corn machine steering bridge produced in China is used in the working environment with high field ridges and soft ground, the steering resistance is large, and the steering is prone to instability, which seriously affects the stability and safety of the whole machine. Chengjun is welded by multiple components, and it is prone to breakage when used in a relatively harsh working environment.

Contents of the invention

The purpose of the utility model is to provide a large-scale corn machine steering bridge assembly with long service life and strong steering stability.

The technical solution adopted by the utility model to solve the technical problem is: the steering bridge assembly for large corn machine, including steering bridge frame, steering assembly, steering rod and wheel assembly, the two ends of the steering bridge frame are connected with steering assembly In this way, the steering assembly includes a steering arm, on which a steering vertical shaft and a steering wheel shaft are arranged, the steering vertical shaft is arranged in the middle of the steering arm, and is rotatably connected with one end of the steering bridge, the steering The wheel shaft is fixedly connected with the wheel assembly on the outside of the steering arm, and the two ends of the steering rod are respectively fixed on the mounting holes on the upper end of the steering arm. An oil cylinder mounting plate is arranged in the middle of the steering bridge, and on both sides of the oil cylinder mounting plate Each is provided with an oil cylinder, the fixed end of the oil cylinder is fixedly connected with the installation plate of the oil cylinder, and the movable end of the oil cylinder is hinged with the lower end of the steering arm.

The steering arm is integrally formed with the steering vertical shaft and the steering wheel shaft.

The beneficial effects of the utility model are: the steering bridge assembly for the large-scale corn machine of the utility model is driven by double oil cylinders, the system stability is strong, and the stability and safety of the steering are guaranteed. The steering assembly is composed of a steering arm, The steering vertical shaft and the steering wheel shaft are integrally formed, which increases the service life and is not easy to be damaged during the steering process.

Detailed ways

The technical scheme of the utility model is further illustrated below through specific examples.

As shown in Figure 1-2: the steering axle assembly for a large corn machine includes a steering bridge 1, a steering assembly 2, a steering tie rod 3 and a wheel assembly 4, and the two ends of the steering bridge 1 are rotatably connected to the steering assembly 2. The steering assembly 2 includes a steering arm 21 on which a steering vertical shaft 22 and a steering wheel shaft 23 are arranged. The steering vertical shaft 22 is arranged in the middle of the steering arm 21 and connected to the steering bridge 1 The steering wheel shaft 23 is fixedly connected with the wheel assembly 2 on the outside of the steering arm 21, and the two ends of the steering rod 3 are respectively fixed on the mounting holes on the upper end of the steering arm 21. There is an oil cylinder mounting plate 5, an oil cylinder 6 is respectively arranged on both sides of the oil cylinder mounting plate 5, the fixed end of the oil cylinder 6 is fixedly connected with the described oil cylinder mounting plate 5, and the movable end of the oil cylinder 6 is connected with the steering arm The lower ends of 21 are hinged.

Preferably, the steering arm 21 is integrally formed with the steering vertical shaft 22 and the steering wheel shaft 23 .

The steering bridge assembly for a large corn machine of the utility model is driven by double oil cylinders 6, the system stability is strong, and the stability and safety of steering are guaranteed. The steering assembly is composed of a steering arm 21, a steering vertical shaft 22, and a steering wheel shaft. 23 is integrally formed, which increases the service life and is not easy to be damaged during the steering process.

Except for the technical features described in the description, all are technologies known to those skilled in the art.
