example 1

[0032] Example 1 - passing a vertical obstacle

[0033] Such as image 3 and Figure 4 As shown, when the car moves at a speed V and encounters an obstacle 100 whose height exceeds the radius of the wheel, since the driving force of the whole vehicle cannot generate an upward component on the front wheel (except for the upward component generated by the rotation of the front wheel), In this way, the car cannot pass through obstacles normally.

[0034] At this time, by manipulating the trigger device in the cab, the first hydraulic oil chamber 4 in the multi-function vehicle oil cylinder connected to the front axle will release hydraulic oil, the second hydraulic oil chamber 10 will be filled with hydraulic oil, and the second hydraulic oil chamber 10 will be filled with hydraulic oil. The pressure in the oil chamber 10 rises to make the piston 7 go up, thereby lifting the front axle, making the front axle wheel 200 off the ground, and the height of the axle from the ground e...

example 2

[0035] Example 2 - Through the trench

[0036] Such as Figure 5 As shown, when the car moves at a speed V and encounters a ditch 300 with a width greater than the diameter of the wheel, the wheel 200 will stretch the suspension system under the action of its own gravity and descend. Unable to get upward component force (except for the upward component force produced by the rotation of the front wheels), the car cannot pass through the ditch normally.

[0037] At this time, by manipulating the trigger device in the cab, the first hydraulic oil chamber 4 in the multi-function vehicle oil cylinder connected to the front axle will release hydraulic oil, the second hydraulic oil chamber 10 will be filled with hydraulic oil, and the second hydraulic oil chamber 10 will be filled with hydraulic oil. The pressure in the oil chamber 10 rises to make the piston 7 go up, thereby lifting the front axle and making the front axle wheel 200 rise. The height of the axle from the ground is l...

Abstract

The invention discloses an oil and gas cylinder for a multipurpose vehicle and a user method of the oil and gas cylinder. The oil and gas cylinder for the multipurpose vehicle comprises an oil and gascylinder housing (3) which is fixedly arranged on a frame as well as a first isolation pad (5) and a second isolation pad (9) which are respectively arranged inside the oil and gas cylinder housing (3) in a slidable manner and are vertically arranged, wherein the inner part of the oil and gas cylinder housing (3) is divided into an upper area, a middle area and a lower area which are isolated from one another by the first isolation pad (5) and the second isolation pad (9); the oil and gas cylinder housing (3) is provided with a first oil hole (2) communicated with the upper area; the oil andgas cylinder for the multipurpose vehicle further comprises a piston (7) which is arranged in the middle area in a slidable manner; a joint pin (71) is arranged at the bottom of the piston (7) and isconnected with an axle; the oil and gas cylinder housing (3) is also provided with a second oil hole (11) communicated with the lower area. The oil and gas cylinder for the multipurpose vehicle and the user method of the oil and gas cylinder, disclosed by the invention, have the advantages of ingenious design and high practicality.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a multifunctional vehicle oil cylinder and a method for using the same. Background technique [0002] Such as figure 1 as shown, figure 1 A structural schematic diagram of an existing vehicle oil cylinder is shown ( figure 1 A possible damping structure is not shown). The vehicle oil cylinder includes an oil cylinder housing 3, which is arranged on the oil cylinder housing 3 and is used to fix the oil cylinder housing 3 on the vehicle frame (not shown in the figure). 3. The interior of the oil cylinder shell 3 is divided into the isolation pad 5 of the upper area and the lower area that are isolated from each other. The oil cylinder shell 3 is provided with an oil filling hole 2, so that the upper area is used as the hydraulic oil chamber 4; the vehicle oil The cylinder also includes a piston 7 that is slidably arranged in the lower area to divide the lower area into a high-pressure...
