[0002] Heavy truck is the abbreviation of heavy truck, which is an authentic, traditional and informal name for heavy trucks and semi-trailer tractors, including all kinds of special vehicles, dump trucks, trucks and some trucks that you see on the road. For the rare off-road vehicles, for heavy trucks with cabs weighing more than 500kg, the traditional manpower turning and driving turning system and structure locked by a mechanical torsion bar mechanism can no longer adapt, and the hydraulic turning and locking mechanism is used instead. Instead, the traditional heavy-duty cab overturn control mechanism can only be controlled by one of the manual or electric control methods. The control method is single and there is no safety guarantee. Once the control fails, there is no backup control method, which will cause accidents. major safety hazard

Embodiment 1

[0042] When the present invention is in use, a bearing is installed on the eccentric shaft of the motor of the electric and manual integrated heavy truck cab overturn control mechanism, forming a cam structure. During the upward linear movement of the lower part of the plug sleeve 301 , the hydraulic oil overcomes the resistance of the one-way valve assembly 302 at the bottom of the plunger sleeve 301 and is sucked into the cavity formed by the plunger rod 305 and the plunger sleeve 301 from the oil suction port 303 . When the bearing rotates to the lowest point, the bearing presses the plunger rod 305 downward, and the plunger rod 305 overcomes the resistance of the hydraulic spring 306 and moves downward. At this time, the one-way valve assembly 302 is closed, and the plunger rod and the plunger sleeve cavity The hydraulic oil in the pump cannot be discharged from the bottom oil suction port 303, and can only flow into the oil passage in the pump body from the oil discharge h...

Embodiment 2

[0045] When the present invention is in use, when the electric part breaks down, the manual plunger pump can be adjusted through the reversing valve to complete the work of the cab overturn control system, mainly to cooperate with the pump body 1 of the electric and manual integrated heavy truck cab overturn control mechanism In use, by pressing the handle 605, the hydraulic plunger rod 601 makes a linear reciprocating motion to complete the oil suction and oil discharge operations of the manual part.

[0046] The invention can be used even when the power is cut off, which effectively improves the scope of application of the invention and has stronger flexibility of use.

Embodiment 3

[0048] When the present invention is in use, the hydraulic oil in other parts connected to the electric and manual integrated heavy truck cab turning control mechanism flows back into the plunger pump, and the internal hydraulic oil in the oil tank 2 connected to the pump body 1 is full , the hydraulic oil can overcome the resistance of the one-way valve inside the overflow valve plug, open the one-way valve, discharge the hydraulic oil out of the system, protect the electric and manual integrated heavy truck cab overturn control mechanism, and avoid damage to parts. The nut body 701 There is an empty overflow oil hole 702 in the middle, and there is a steel ball 703 on the upper part of the overflow oil hole 702. When the oil in the system is full, it will overcome the resistance of the hydraulic spring 704 and push the steel ball 703 away, so that the hydraulic oil flows out of the oil discharge hole. 705 is discharged, and the hydraulic spring 704 and the steel ball 703 are ...

Abstract

The invention discloses a heavy truck cab turning control mechanism and a use method thereof. The heavy truck cab turning control mechanism comprises a base and a main body of a pump body, wherein the main body of the pump body is arranged on the base; an oil tank is arranged inside the top end of the main body of the pump body; the top of the oil tank is provided with an oil box filter screen installing hole; the surface of the main body of the pump body is provided with an overflow valve assembly installing hole leading to the inside of the main body of the pump body; one side wall of the base is provided with an electric plunger pump installing hole, a manual plunger pump installing hole and an overflow valve plug installing hole; the corresponding other side wall is provided with an oil pipe joint; the side wall of the base is provided with a reversing valve installing hole; the surface of the top of the main body of the pump body is provided with an oil box filter screen installing hole. The conversion of two sets of hydraulic oil paths inside the pump body is realized through a reversing valve; when the electric control fails, a hydraulic system can be manually controlled; the selection of an alternative scheme is realized; the safety in the driving process is improved.
