Automobile driving-cabin diverter

Abstract

Disclosed is a vehicle cab turnover device, in particular to a vehicle cab hydraulic turnover which enables the vehicle cab drop automatically to the lowest point after climbing over the unstable equilibrium point of barycenter. The invention solves the technical problem that the damping device which produces a damping effect during the process of the vehicle cab barycenter climbing over the unstable equilibrium point and turning over forward to the lowest point does not play damping effect when the vehicle cab climbs up forward from the initial position to the unstable equilibrium point of barycenter and when the vehicle cab turns over backward from the lowest point to the initial position. The invention is characterized in that an active damping plug is arranged between a spherical one way valve and a reset spring of a reversing valve with an output one-way valve in the oil pump main body. The invention can not only avoid the vehicle cab fast falling to the lowest point after climbing over the unstable barycenter equilibrium point, but also save additional stroke control device; and has a small operation torque and high mechanical efficiency.

Description

technical field [0001] The invention relates to an automobile cab hydraulic turner for turning over an unstable balance point of the center of gravity of a car, in particular to a hydraulic turner for a car cab which turns over an unstable balance point of the center of gravity and automatically falls to the lowest point. Background technique [0002] For the convenience of maintenance and safety considerations of various kinds of automobile cabs, the forward-turning stroke will cross the larger angle of the unstable balance point of the center of gravity. This kind of automobile cab, after overturning over the unstable balance point of the center of gravity, if there is no effective control, will inevitably fall to the lowest position because of its own weight, resulting in a larger harmful impact. In order to weaken this impact, two designs of current cab hydraulic turners are adopted. [0003] The basic scheme of the first design and how it works is: [0004] 1. There a...

Problems solved by technology

[0013] At present, the oil pumps involved in all the hydraulic overturners of the car cab whose center of gravity has turned over the unstable balance point do not participate in the car cab, which will inevitably fall to the lowest position faster and faster due to its own weight, which will cause greater damage. Effective Control of Shock
