Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples:

as shown in fig. 1, fig. 2 and fig. 3 together, an embodiment of the rear articulated off-road forklift of the present utility model includes a front body 1 and a rear body 2, a cab 4 and a front axle 3 are disposed on the front body 1, a rear axle 5 is disposed on the rear body 2, a fork mechanism 10 for fork loading goods is further disposed at the front part of the front body 1, and during fork loading operation, the distance between a driver in the cab 4 and the goods on the fork mechanism 10 is smaller, so that the driver has a better driving field of view, and a certain potential safety hazard can be eliminated. In addition, the front car body 1 and the rear car body 2 are hinged through the vertical hinge shaft 6, the distance from the hinge shaft 6 to the center position of the front car axle 3 is larger than the distance from the hinge shaft 6 to the center position of the rear car axle 5, when a driver operates in the cab 4, the rear car body 2 can rotate in the left-right direction in the horizontal plane by taking the hinge shaft 6 as the center, and the front car body 1 does not rotate, and the advantage of the structure is that the weight of cargoes is concentrated on the fork mechanism 10, the front car axle 3 receives larger weight, the rear car axle 5 receives smaller weight, the rear car axle 5 is easier to steer, and when the front car axle 1 steers, two tires on the front car axle 1 receive great extrusion force, so the safety of the whole car can be ensured by using the steering of the rear car body 2, and the risk of overturning is not easy to occur. The steering structure of the rear vehicle body 2 also makes the turning radius of the whole vehicle small, so that it can perform work in a small space.

The joint of the front car body 1 and the rear car body 2 is provided with V-shaped plates 8 which extend out in opposite directions, the tip ends of the two V-shaped plates 8 are connected in a hinged manner through a hinge shaft 6, two sides of the hinge shaft 6 are symmetrically provided with oil cylinders 7, and two ends of the oil cylinders 7 are respectively connected to the front car body 1 and the rear car body 2 in a hinged manner. A horizontal cross beam 9 is also fixed in the middle of the front vehicle body 1, one end of each of the two oil cylinders 7 is hinged at two ends of the horizontal cross beam 9, and the other end of each of the two oil cylinders is symmetrically hinged on the V-shaped plate 8 on the rear vehicle body 2. Therefore, when the driver controls, the two cylinders 7 are alternately telescopic, so that the rear vehicle body 2 rotates around the hinge shaft 6, and finally the steering of the whole vehicle is realized.

As shown in fig. 2, the arrow direction indicates the forward direction of the off-road forklift, and when the driver controls one cylinder 7 to extend to the longest and the other cylinder 7 to retract to the shortest, the right turn of the whole forklift can be realized; as shown in fig. 3, when the driver controls the two cylinders 7 to alternate, the left turn of the whole vehicle is realized. In addition, in the process of steering of the off-road forklift, as a few tons of heavy goods are all borne on the forklift mechanism 10, and the two tires corresponding to the front forklift body 1 bear heavy pressure, the two tires of the front axle 3 are prevented from being extruded during steering by controlling the steering of the rear forklift body 2, so that the risks of tire burst and forklift overturning are eliminated. The turning radius of the whole off-road forklift is greatly reduced due to the structural form of the steering of the rear forklift body 2, so that the whole forklift can be easily steered in a narrow working space. Through calculation of actual data, the maximum angle of the rear vehicle body 2 when the rear vehicle body rotates around the hinge shaft 6 is +/-50 degrees (shown in fig. 3) during left and right rotation of the rear articulated off-road forklift can meet the requirements of various working scenes.

Finally, the fork assembly mechanism 10 of this embodiment includes a vertical mast 11 and a fork support 12 that goes up and down along the mast 11, a control cylinder 13 for controlling the inclination angle of the mast 11 is connected between the mast 11 and the front vehicle body 1, before fork assembly, the mast 11 can be tilted forward by the control cylinder 13, so that the fork support 12 is close to the ground as much as possible, and the bottom of the goods can be conveniently inserted. When lifting goods, the portal 11 can be backward inclined by controlling the oil cylinder 13, so that the goods can be prevented from falling off the fork support 12 due to jolt in the walking process.

In summary, the rear hinged off-road forklift is simple in structure, convenient to use, small in turning radius, suitable for operation in a narrow space, free of risks of tire burst and overturning, and good in safety and practicality.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
