Abstract
Description
Technical Field
[0001] This utility model relates to the field of forklift technology, and in particular to a rear-steering off-road forklift. Background Technology
[0002] In our daily lives, forklifts have become a common tool for loading, unloading, moving, and transporting goods. However, in harsh terrain conditions, ordinary forklifts cannot operate, which is why off-road forklifts have emerged.
[0003] Currently, most off-road forklifts use articulated steering structures. Due to structural limitations, their wheelbases are often too long, resulting in a loose structure, excessively large turning radii, poor maneuverability, and an inability to operate in confined spaces. When working in the field, the load center of the vehicle frequently shifts due to uneven terrain, leading to a decrease in overall vehicle stability, balance, and overall performance. Furthermore, the counterweights used for balancing on four-wheel-drive off-road forklifts are too heavy, significantly increasing fuel consumption. Additionally, components at the steering articulation points are prone to damage, increasing operating costs. Moreover, safety hazards may arise during use. Utility Model Content
[0004] Technical objective: In order to overcome the shortcomings of the existing technology, this utility model provides a rear-steering off-road forklift.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rear-steering off-road forklift, which includes a front frame, a rear frame is provided on the rear side of the front frame, a pair of first articulated frames are vertically arranged at the center of the rear side of the front frame, and two pairs of second articulated frames are vertically arranged on the front side of the rear frame; each first articulated frame is located between each pair of second articulated frames, and each first articulated frame is hinged to each pair of second articulated frames; a pair of hydraulic cylinder frames are provided at the bottom of the second articulated frames above the rear frame, and a steering cylinder is provided inside the hydraulic cylinder frame, with the other end of the steering cylinder horizontally connected to the rear side of the front frame.
[0006] Preferably, the engine is located on the rear side of the front frame, above the topmost first articulated frame, with the top of the engine higher than the top of the front frame, and a rear cover is located above the engine.
[0007] Preferably, a cab is located above the front frame, and the cab is located in front of the rear hood.
[0008] Preferably, a counterweight box is provided on the rear side of the rear frame.
[0009] Preferably, a reinforcing beam is provided on the rear frame.
[0010] The beneficial effects of this utility model are:
[0011] This utility model provides a rear-steering off-road forklift, which, by setting up a cylinder frame and a steering cylinder, works together to cause mutual deflection between the front frame and the rear frame, thereby achieving rear wheel deflection. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1 To be continued Figure 2 The principles and features of this utility model are described, and the examples given are only used to explain this utility model and are not intended to limit the scope of this utility model.
[0018] Please see Figures 1-2This utility model provides a rear-steering off-road forklift, which includes a front frame 1, a rear frame 2 disposed at the rear of the front frame 1, a pair of first articulated frames 3 vertically disposed at the center of the rear of the front frame 1, and two pairs of second articulated frames 31 vertically disposed at the front of the rear frame 2; each first articulated frame 3 is located between each pair of second articulated frames 31, and each first articulated frame 3 is hinged to each pair of second articulated frames 31; a pair of hydraulic cylinder frames 4 are disposed at the bottom of the second articulated frames 31 above the rear frame 2, and the hydraulic cylinders... The frame 4 is equipped with a steering cylinder 41, the other end of which is horizontally connected to the rear side of the front frame 1. The front frame 1 and the rear frame 2 are hinged by a first articulation frame 3 and a second articulation frame 31. The steering cylinder 41 is fixed between the front frame 1 and the rear frame 2 by the cylinder frame 4. The two steering cylinders 41 on the first articulation frame 3 and the second articulation frame 31 drive the front frame 1 and the rear frame 2 to rotate relative to each other. The steering cylinder 41 can be locked to improve the connection rigidity of the front frame 1 and the rear frame 2 when driving straight.
[0019] Please see Figures 1-2 An engine 13 is installed on the rear side of the front frame 1. The engine 13 is located above the topmost first articulated frame 3. The top of the engine 13 is higher than the top of the front frame 1. A rear cover 12 is installed above the engine 13. The engine 13 drives the front frame 1 and the rear frame 2 to move, and the rear cover 12 protects the engine 13.
[0020] Please see Figures 1-2 A cab 11 is provided above the front frame 1, and the cab 11 is located in front of the rear cover 12; the overall movement direction is controlled by the cab 11.
[0021] Please see Figures 1-2 A counterweight box 21 is provided on the rear side of the rear frame 2; the counterweight box 21 is used to balance the weight difference between the front frame 1 and the rear frame 2.
[0022] Please see Figures 1-2 The rear frame 2 is equipped with a reinforcing beam 22; the reinforcing beam 22 strengthens the rear frame 2 and prevents the two steering cylinders 41 from damaging the structure of the rear frame 2 when they drive the rear frame 2 to rotate.
[0023] During use, the driver controls the movement from the cab 11. When steering is required, the two steering cylinders 41 between the front frame 1 and the rear frame 2 extend and retract respectively, causing the front frame 1 and the rear frame 2 to deflect and achieve rear wheel steering.
[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
