Problems solved by technology
The steering of the folded small tractor is different from that of ordinary cars. It mainly realizes the steering through the folded mechanism connecting the front frame and the rear frame. Rotating in the vertical direction, the two front wheels cannot adjust to the change in road surface height in time, so that the traction bearing is subjected to a large torsional moment, and the front frame of the tractor is upturned, and the steering mechanism is deformed, which increases the resistance of the steering. , the steering is laborious, and the wear of the parts is accelerated

Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings.
[0016] Such as Figure 1-Figure 4 As shown, a waist steering mechanism of an agricultural tractor includes a traction pin lower fixing plate 1, a cushion block 2, a vertical baffle plate 3, a traction pin upper fixing plate 4, a traction pin 5, a traction pin cover 6, a traction shaft 7, and a traction pin Front fixed plate 8 of axle sleeve, traction axle sleeve 9, traction shaft cover plate 10, rear fixed plate 11 of traction axle sleeve, traction axle nut 12, rear vehicle frame girder 13, limit nail 14 and limit plate 15.
[0017] The traction pin 5 passes through the traction pin hole on the traction shaft 7, is installed vertically between the two traction pin covers 6, the axis is perpendicular to the axis of the traction shaft 7, and the traction pin cover 6 is installed on the traction pin to fix the plate 4 and the traction pin. Pin down on the fixed plate 1. ...

The invention discloses an articulated steering mechanism for an agricultural tractor. According to the articulated steering mechanism, a traction pin hole is formed in one end of a traction shaft, a traction pin penetrates through the traction pin hole and is vertically installed between two traction pin sealing covers, the axis of the traction pin is vertical to the axis of the traction shaft, and the two traction pin sealing covers are installed on an upper traction pin fixed plate and a lower traction pin fixed plate respectively; the other end of the traction shaft penetrates through a traction shaft sleeve, the two ends of the traction shaft sleeve are installed on a front traction shaft sleeve fixed plate and a rear traction shaft sleeve fixed plate, and the left end and the right end of each of the front traction shaft sleeve fixed plate and the rear traction shaft sleeve fixed plate are fixed on a rear frame crossbeam respectively; the tail end penetrating through the traction shaft sleeve, of the traction shaft, is screwed by a traction shaft nut; and limit plates are installed at the two sides of the front end of the traction shaft, and limit nails are installed on the front traction shaft sleeve fixed plate and corresponding to the limit plates. The articulated steering mechanism disclosed by the invention improves the adaptability of front wheels to a road surface, improves the road holding force of the tractor, and reduces the torsional moment stressed by the traction shaft, so that the articulated steering mechanism is small in deformation and low in steering resistance.
Description
technical field [0001] The invention relates to a folding steering mechanism of an agricultural tractor. Background technique [0002] At present, small agricultural tractors are widely used in towns and rural areas, and the common types are all bent waists. As the main means of transport for rural goods, more and more people are paying attention. The steering of the folded small tractor is different from that of ordinary cars. It mainly realizes the steering through the folded mechanism connecting the front frame and the rear frame. Rotating in the vertical direction, the two front wheels cannot adjust to the change in road surface height in time, so that the traction bearing is subjected to a large torsional moment, and the front frame of the tractor is upturned, and the steering mechanism is deformed, which increases the resistance of the steering. , the steering is laborious, and the wear of the parts is accelerated. Contents of the invention [0003] The technical p...
