Detailed Description

The utility model is further illustrated by the figures and examples.

As shown in fig. 1: the utility model provides a hydraulic steering wheel testing platform, includes frame 1, locates on frame 1 and adjusts pole 2, and the end connection who adjusts pole 2 has adjustment subassembly, and adjustment subassembly includes connecting rod 3, and connecting rod 3 pin joint is on frame 1, and the distal end of connecting rod 3 is equipped with the setting element, adopts the mode of manual regulation to realize spacing behind the swivelling joint pole 3. The connecting rod 3 is hinged with the adjusting rod 2, and the circumferential rotation between the connecting rod and the adjusting rod is realized by driving the cylinder 4.

Specifically, referring to fig. 1-2, a cylinder 4 is arranged at the connection position of the connecting rod 3 and the upper end of the adjusting rod 2, the output end of the cylinder 4 is hinged with the adjusting rod 2 through a shaft block 6, the tail end of the cylinder is hinged with the connecting rod 3 through the shaft block 6, the cylinder 4 is in an extending/outputting state in a normal state, and the adjusting rod 2 can circumferentially rotate relative to the connecting rod 3 during return/retraction. To quickly adjust the position and angle of the oil pump of the steering gear 12 to the desired position.

The structural schematic diagram of the positioning piece is shown in fig. 2, wherein an arc-shaped notch 7 is formed in the frame 1, the far end of the connecting rod 3 horizontally extends and is provided with a through groove, the arc-shaped notch 7 is provided with limiting grooves 8 distributed along the distribution track of the arc-shaped notch, and the through groove is inserted into the corresponding limiting grooves 8 through an external inserting rod 11 to realize fixation. When the position of the connecting rod 3 is horizontally rotated and adjusted, the external inserted rod 11 is lifted up, the connecting rod 3 is rotated to a required position and then is sunk into the corresponding limit groove 8, and the whole adjusting assembly is fixed.

The basic profile of the steering wheel 12 is shown in fig. 3. A conventional clamping mechanism basically employs a screw rotation to move a movable clamp block toward another fixed clamp block to clamp the steering wheel 12. If the shape of the clamping block adopts a flat common clamping block, the shape of the steering wheel 12 is difficult to match, the clamping effect is poor, and if the special arc-shaped notch 7 is adopted for matching and clamping, the steering wheel 12 can be always placed in a horizontal state, and the operation and the detection are inconvenient.
