Embodiment Construction

[0017] Further details will be described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 , figure 2 As shown, the present invention includes a front hinged seat 1 , a hinged outer drum 3 , a hinged connection assembly 2 and an inner drum 4 . Such as image 3 and Figure 4 As shown, an upper front hinged ear 1-1 and a lower front hinged ear 1-2 are arranged on the front hinged seat 1, and an upper drum hinged ear 3-1 and a lower drum hinged ear 3-2 are arranged at the front end of the hinged outer drum 3. . Such as Figure 5 The hinged connection assembly 2 shown includes a connecting pin shaft 2-1, a seal ring 2-2, a joint bearing 2-3, an O-ring 2-4, a washer 2-5, a compression washer 2-6, and a round nut 2-7. Because the upper front hinge ear 1-1 has the same structure as the lower front hinge ear 1-2, the upper drum hinge ear 3-1 has the same structure as the lower drum hinge ear 3-2, and the upper front hinge ear 1-1 has the same struc...

Abstract

The invention discloses an articulated mechanism of an articulated tractor. The articulated mechanism comprises a front articulated seat, an articulated outer drum, articulated connecting assemblies and an inner drum. The front articulated seat is provided with an upper front articulated lug and a lower front articulated lug. The front end of the articulated outer drum is provided with an upper drum articulated lug and a lower drum articulated lug. The upper front articulated lug and the upper drum articulated lug are articulated by the front articulated seat through one articulated connectingassembly, and the lower front articulated lug and the lower drum articulated lug are articulated by the front articulated seat through the other articulated connecting assembly, so that the front articulated seat is articulated to the articulated outer drum. The inner drum is sleeved into the articulated outer drum, the front end and the rear end of the inner drum are respectively provided with abushing, the inner drum and the articulated outer drum are separated by the bushings, and the front end of the inner drum is provided with a drum connecting end cover and a limit snap spring. By means of the two sets of articulated connecting assemblies, the front articulated seat and the articulated outer drum are articulated together, the rolling steering is smooth, and the work is stable and reliable. The bushings are adopted to bear abrasion for the articulated outer drum and the inner drum. The hinge mechanism is simple in installation, convenient to replace and low in cost.

Description

technical field [0001] The invention relates to a hinge mechanism of a waist-steering tractor, belonging to the technical field of connection mechanism preparation of agricultural machinery tractors. Background technique [0002] The waist steering tractor has a broad market space due to its small turning radius, lightness, flexibility, and strong off-road capability, and the performance of the hinge mechanism of the waist steering tractor determines the safety and reliability of the product. At present, in the design of the hinge mechanism of the waist steering tractor on the market, the hinge point is generally in the form of a single pin shaft, and the roller is made of all-steel material, which is easy to cause problems such as fast wear of the roller, short life cycle, and high replacement cost. Moreover, the rotation of the hinge point is not smooth, the overall installation is difficult, and the maintenance cost is high. Therefore, providing a tractor hinge mechanism...
