Embodiment 1

[0024] Such as figure 1 as shown in figure 1 , 2 As shown, Embodiment 1 includes: a front frame 1, a two-degree-of-freedom hinge mechanism 2, a hydraulic steering mechanism 3, and a rear frame 4. The front frame 1 is connected to the rear vehicle through a two-degree-of-freedom hinge mechanism 2 and a hydraulic steering mechanism 3. The frame 4, the two free hinge mechanisms 2 and the hydraulic steering mechanism 3 realize the longitudinal swing along the direction of the frame and the lateral rotation along the vertical axis between the front frame 1 and the rear frame 4, which improves the steering of the vehicle when driving off-road. The ability and the grounding performance of the tires meet the requirements of wild off-road driving.

[0025] Such as image 3 As shown, the front frame 1 of embodiment 1 is made up of front frame steel structure 5, two front frame wheels 6, two sets of wheel side hydraulic drive devices 7 and spherical hinge supports 8, and the two front...

Embodiment 2

[0030] Such as Figure 6 As shown, on the basis of Embodiment 1, two sets of identical hydraulic steering mechanisms 3 are symmetrically arranged on both sides of the two-degree-of-freedom hinge mechanism 2 to form Embodiment 2; two sets of symmetrically arranged hydraulic steering mechanisms 3 can be used to increase The stability of the vehicle when turning, improves the steering ability and dynamic characteristics of the vehicle, and meets the requirements of off-road driving in the wild.

Abstract

The invention relates to an articulated field operation vehicle chassis, comprising a front vehicle frame, a two-degree-of-freedom articulated mechanism, a hydraulic steering mechanism and a rear vehicle frame, the front vehicle frame is connected with the rear vehicle frame through the two-degree-of-freedom articulated mechanism and the hydraulic steering mechanism, the front vehicle frame and the rear vehicle frame adopt dual-U-shaped frameworks, the two-degree-of-freedom articulated mechanism and the hydraulic steering mechanism realize the longitudinal oscillation along the vehicle frame direction between the front vehicle frame and the rear vehicle frame and the transverse rotation along the direction of a plumb shaft; and the articulated chassis adopts a wheel-side hydraulic driving device for constituting a four-wheel full-driving system, thereby improving the off-load driving performance and the traction performance of the articulated chassis. The articulated field operation vehicle chassis adopts the four-wheel full hydraulic driving system, the dual-U-shaped frameworks and the two-degree-of-freedom articulated mechanism, thereby not only having the off-load driving performance which is applicable to complicated field terrain environments, but also having good traction performance, flexible mobility and road adaptability, thereby further being capable of meeting the filed operation requirements and being particularly applicable to military filed material handling and other filed operations.

Description

technical field [0001] The invention belongs to the field of engineering transport vehicle manufacturing, in particular to a chassis of an articulated field operation vehicle. Background technique [0002] The modernization of my country's national defense and the army has a large demand for high-mobility, high-passing special vehicles and vehicle chassis with off-road functions. Special vehicles with good off-road performance play a pivotal role in modern warfare. The number of equipment And the degree of popularity largely determines the mechanization level and maneuvering speed of the troops. This type of vehicle also plays an important role in anti-terrorism, anti-riot, consolidating national defense, and maintaining social stability. [0003] The vehicle chassis is the main load-bearing part of the vehicle, its strength and rigidity are very important in the overall design of the vehicle. The adaptability to different roads is also a key factor affecting the efficiency ...
