Embodiment Construction

[0028] The present invention will be further described below in conjunction with the embodiments and accompanying drawings. Please refer to the accompanying drawings, see by the figure, in the present embodiment:

[0029]In the reversing valve hole of the pump housing 32 of the oil pump or the main oil pump, a reversing valve with an output check valve is housed. In the reversing valve body 16 of the reversing valve, the reversing valve oil inlet horizontal hole 13, the central oil inlet hole 12, the output check valve seat sealing belt 9, the stroke hole section 22, and the main working hole section are sequentially formed. 2. The guide hole section 28, the stroke hole section 22, the main working hole section 2, and the guide hole section 28 form the valve chamber of the reversing valve. The mouth of the valve chamber is equipped with a plug 35, and the plug pin 34 locks the plug 35. In this valve chamber, starting from the output check valve seat sealing band 9, a spherica...

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...
