Abstract
The utility model provides an oil pump assembly for an overturning device in a commercial automobile cab, which comprises an oil bath, a pump body, a plunger and a distributing shaft. The plunger and the distributing shaft are integrated into the pump body; an oil outlet is arranged on the pump body; the hole series of the distributing shaft is matched with that of the pump body to form a reversing distribution valve; the reversing distribution valve is communicated with the oil outlet of the pump body; a clearance is formed between the distributing shaft and the pump body; one end of the distributing shaft is connected with a rotating mechanism; the oil bath is mounted on the end surface on the other side of the pump body; and an oil absorption hole is formed at the lower end of the plunger, penetrates the pump body, and is communicated with the oil bath. By using the oil pump assembly for the overturning device in the commercial automobile cab, the reversing distribution valve formed by matching the hole series of the distributing shaft and the hole series of the pump body, thereby effectively simplifying the oil passage of an oil pump and reducing the production cost; and because the annular clearance is arranged between the distributing shaft and the pump body, the fluid flow capacity in the system can be restrained during the descending process of the cab, and the accidents caused by the high descending speed of the cab are avoided.
Description
Technical field
The utility model relates to a kind of commercial car cab tilting device oil pump assy.
Background technology
At present, the driver's cab turnover oil pump device generally is to be assembled by the pump housing, oil sump, commutation distributing valve, plunger, distribution shaft, complex structure, cost height; In addition, for fear of too fast the having an accident of operator's compartment decline, generally can go out to be provided with the oil return flow that throttling pore limits oil pump at the oil inlet of oil cylinder, still this throttling pore can make the system pressure loss greatly, and very easily stop up, and causes oil circuit not smooth.
Summary of the invention
The utility model provides a kind of commercial car cab tilting device oil pump assy, can effectively reduce the manufacturing cost of product, simplifies the oil pump oil circuit, reduces the production difficulty, can effectively avoid throttling pore to stop up simultaneously.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: described commercial car cab tilting device oil pump assy, comprise oil sump, the pump housing, plunger, distribution shaft, rotating mechanism; rocking arm; plunger; distribution shaft is integrated in the pump housing; the pump housing is provided with oil outlet; it is characterized in that: the hole of described distribution shaft system matches with the hole system of the pump housing and forms the commutation distributing valve; this distributing valve that commutates is communicated with the oil outlet of the pump housing; be provided with throttle clearance between the distribution shaft and the pump housing; distribution shaft one end is connected with rotating mechanism; the end face of a side of the pump housing is provided with rocking arm; rocking arm links to each other with plunger in the pump housing; the end face of the opposite side of the pump housing is equipped with oil sump, and the plunger lower end is provided with oil-sucking hole, and this oil-sucking hole passes the pump housing and is communicated with oil sump.
To improvement of the technical scheme: described rotating mechanism is a reversing handle.
Technique scheme is further improved: described oil sump is installed on the pump housing by screw.
Beneficial effect:
Use commercial car cab tilting device oil pump assy described in the utility model, the commutation distributing valve is to be to match to form by the hole of distribution shaft system with the hole of the pump housing, so just can effectively simplify the oil pump oil circuit, thereby reduce production costs; The mode of employing gap throttling limits the oil return flow of oil pump between the distribution shaft and the pump housing, can strict Control Allocation axle and the pump housing between gap value reach control operator's compartment return speed, avoid too fast the having an accident of operator's compartment decline, and can not result in blockage, simple in structure; Oil sump is installed on the pump housing by screw, can make things convenient for installing/dismounting.
