Embodiment

[0031] Referring to Figure 1, Figure 2, Figure 3 and Figure 4, the upper-mounted transverse cylinder forklift steering axle includes the bridge body 9, the transverse steering cylinder 7, the connecting rod 6, the left steering knuckle arm 4, the right steering knuckle arm 11, and the steering bend. Plate 5, the piston rods at both ends of the transverse steering cylinder 7 are respectively connected to the connecting rod 6, which is an arc-shaped rod; the other ends of the two connecting rods 6 are respectively connected to the left steering knuckle arm 4 and the right steering knuckle arm 11.

[0032] The bridge body 9 is V-shaped, and the middle of the V-shaped bridge body 9 is vertically connected to the mounting shaft 8 through the retaining ring 14, the thrust washer 15, the shaft sleeve 16, the bushing 17 and the retaining ring 18, as shown in Figure 5, the horizontal steering cylinder 7 is set above the mounting shaft 8, see Figures 2 and 8; the upper ends of the V-shaped ...

Abstract

The invention relates to a forklift steering mechanism, in particular to an upper-mounted horizontal oil cylinder forklift steering bridge. The structural features are: the bridge body is V-shaped, the middle part is vertically connected to the installation shaft, and the horizontal steering oil cylinder is arranged above the installation shaft; The lower end of the pin is axially connected to the L-shaped steering bend, and the lower end of the L-shaped steering bend is connected to the wheel shaft; the other ends of the left steering knuckle arm and the right steering knuckle arm are respectively connected to the middle part of the kingpin. The steering swing angle of the present invention can reach 90 degrees, which is especially suitable for the large steering angle requirement of a double-drive four-point forklift, which cannot be achieved by the prior art products with a steering swing angle of 76-82 degrees. The steering resistance is small, and the steering resistance is 80% of that of the existing similar steering axles.

Description

Technical field [0001] The invention relates to a forklift steering mechanism. Background technique [0002] With the continuous improvement of forklift maneuverability requirements, forklifts are required to have a smaller and smaller turning radius, which requires the steering mechanism of forklifts to achieve larger and larger steering angles. This requirement is especially for front-wheel dual-drive The four-point forklift is particularly important. In addition to requiring the forklift to have a small turning radius, it is also required that the steering resistance of the forklift is as small as possible, especially for battery forklifts, which will make the vehicle more energy-efficient. The steering swing angle of the prior art product is 76-82 degrees, and the layout of the steering bridge has severely restricted the potential of the steering mechanism to achieve a large swing angle, and the steering resistance cannot be further reduced. Summary of the invention [0003]...
