Detailed Description
Referring to fig. 1 to 3, a free wheel adjusting transport vehicle comprises a free wheel type obstacle crossing transport vehicle, wherein the transport vehicle is provided with four free suspensions 10, each free suspension is provided with two wheels 20 arranged front to back, the free wheel adjusting transport vehicle is provided with a free suspension adjusting rod 30, and the free suspension adjusting rod 30 drives the free suspensions 10 to swing.
The free suspension adjusting rod 30 is a telescopic rod, the upper end of the free suspension is provided with a free suspension crank 11, the free suspension crank is provided with a crank shaft 12, two sides of the middle part of the vehicle body are respectively provided with an adjusting rod mounting shaft 41, one end of the free suspension adjusting rod is hinged with the crank shaft 12, and the other end of the free suspension adjusting rod is hinged with the adjusting rod mounting shaft 41.
Four free suspension adjusting rods respectively drive the four free suspensions, and each adjusting rod mounting shaft 41 is connected with two free suspension adjusting rods 30 respectively driving the front free suspension 10 and the rear free suspension 10.
The free suspension adjusting rod is a hydraulic cylinder, an oil cylinder barrel 31 of the hydraulic cylinder is hinged with an adjusting rod mounting shaft 41 of the vehicle body, and a hydraulic rod 32 of the hydraulic cylinder is hinged with a crank shaft of the free suspension crank.
Examples:
as shown in fig. 1 to 3, a free wheel adjusting vehicle, which is a free wheel type obstacle surmounting vehicle, is provided with four free suspensions 10 each having two wheels 20 arranged one behind the other.
The free suspension is swingable about a suspension shaft 13, a free suspension crank 11 is provided at an upper end of the free suspension, a crank shaft 12 is provided at the free suspension crank, and adjustment lever mounting shafts 41 are provided at both sides of a middle portion of a vehicle body 40.
The free wheel adjusting transportation vehicle is provided with four free suspension adjusting rods 30, the four free suspension adjusting rods 30 respectively drive the four free suspensions, and each adjusting rod mounting shaft 41 is connected with two free suspension adjusting rods 30 respectively driving the front free suspension 10 and the rear free suspension 10. In this embodiment, the free suspension adjustment lever is a hydraulic cylinder 30, and the hydraulic cylinder 30 is provided with an oil cylinder tube 31 and a hydraulic rod 32.
