Embodiment Construction

[0005] A specific embodiment of a steering mechanism of an articulated engineering vehicle will be described in detail below in conjunction with the accompanying drawings.

[0006] Such as figure 1 As shown, a steering mechanism of an articulated engineering vehicle includes a steering wheel (1), a steering gear (2), a steering rocker arm (3), a steering sleeve rod (4), a steering knuckle arm (5), and a steering shaft ( 6), dustproof ring (7), upper flange cover (8), round nut (9), tapered roller bearing (10), upper body (11), thrust ball bearing (12), deep groove ball bearing (13), the lower flange cover (14) and the lower body (15). The steering wheel (1) is connected to the input shaft of the steering gear (2) through an involute spline, the steering gear (2) is fixedly installed on the upper vehicle body (11), and the steering crank The arm (3) is firmly connected to the output shaft of the steering gear (2), the steering sleeve rod (4) is connected to the steering rock...

Abstract

The invention designs a steering mechanism of an articulated type engineering vehicle. The steering mechanism comprises a steering wheel (1), a steering gear (2), a steering rocker arm (3), a steering loop bar (4), a steering knuckle arm (5), a steering shaft (6), a dust ring (7), an upper flange cover (8), a circular nut (9), a tapered roller bearing (10), an upper vehicle body (11), a thrust ball bearing (12), a deep groove ball bearing (13), a lower flange cover (14) and a lower vehicle body (15). During working, an output shaft of the steering gear (2) can be driven to rotate through rotating the steering wheel (1), so that the steering rocker arm (3) is driven to rotate, the steering rocker arm (3) can drive the steering shaft (6) to rotate through the steering loop bar (4) and the steering knuckle arm (5), the lower vehicle body is driven to rotate, and the steering function of the vehicle is completed. The whole steering mechanism does not need hydraulic power, and is compact in structure, and requirements for mounting space of a small-scale engineering vehicle can be met.

Description

technical field [0001] The technology claimed in this patent belongs to the technical field of engineering machinery. Background technique [0002] Articulated engineering vehicles have a wide range of market applications, and can be widely used in various indoor and outdoor construction operations such as construction sites, docks, municipal roads, squares, container yards, cargo yards, parking lots, and airport runways. As the steering mechanism of articulated engineering vehicles, hydraulic cylinder actuators are usually used to complete the steering action of the vehicle body through the telescopic movement of the cylinder. However, for some small engineering vehicles, because the installation space of the equipment inside the vehicle body is very narrow, it is impossible to accommodate the hydraulic power steering mechanism that takes up a large installation space. In order to adapt to the compact structure of small engineering vehicles, this patent has invented a stee...
