Embodiment 1

[0027] The integrated electronically controlled reversing oil pump, as shown in the figure, includes a housing 1 and an oil tank 5 connected to the housing 1. The housing 1 is provided with a reversing chamber 10, and the housing 1 is equipped with an oil inlet pipe 11. The oil inlet pipe One end of 11 communicates with oil tank 5, and the other end of oil inlet pipe 11 is oil inlet 110, and oil inlet 110 communicates with the middle part of reversing chamber 10, and reversing valve core 2 is arranged in reversing chamber 10, also includes electromagnetic coil 3. The electromagnetic coil 3 is installed in the casing 1 and the magnetic force generated under the condition of electrification controls the movement of the reversing valve core 2. The reversing chamber 10 is also connected with the first oil outlet 12 and the second oil outlet 13. The first oil outlet 12 and the second oil outlet 13 are respectively located on the left and right sides of the reversing chamber 10, and ...

Embodiment 2

[0037] The same as the embodiment 1, the difference is that the cylinder 21 is provided with a spiral drainage groove 211 , and the groove bottom of the spiral drainage groove 211 is evenly laid with a plurality of protrusions 212 . Through the design of the spiral drainage groove 211, the pressure oil entering the reversing chamber 10 is spirally buffered.

Embodiment 3

[0039] Same as embodiment 2, the difference is that the left and right sides of the cylinder 21 are provided with positioning grooves 213, the distance between the positioning grooves 213 on the same side of the reversing valve core 2 and the sealing ring 22 is 35 mm, and a buffer ring is also included The plate 24 and the buffer ring plate 24 are installed in the positioning groove 213 and rotate around the buffer groove 213 . The pressure oil is buffered twice through the rotatable buffer ring plate 24 to prevent the pressure oil from directly impacting the protruding ring 23.

Abstract

The invention relates to a power device for an automobile cab lifting and falling system, and discloses an integrated electric control reversing oil pump. The oil pump comprises a shell body (1) and an oil tank (5), a reversing cavity (10) is arranged in the shell body (1), an oil inlet pipe (11) is arranged on the shell body (1), a reversing valve element (2) is arranged in the reversing cavity (10), the oil pump further comprises an electromagnetic coil (3), a first oil outlet (12) and a second oil outlet (13) further communicate in the reversing cavity (10), and the reversing valve element(2) moves to control the oil inlet pipe (11) and the first oil outlet (12) or the oil inlet pipe (11) and the second oil outlet (13) to be connected or disconnected. According to the integrated electric control reversing oil pump, the labor intensity of operators is reduced, and extension of the automatic control operation is facilitated; and meanwhile, the shell body, a reversing mechanism and anelectric pump are highly integrated, so that the installation and layout of a whole vehicle are facilitated, the external protection can be additionally arranged, and the service life of the productcan be prolonged.

Description

technical field [0001] The invention relates to a power device for a lifting and lowering system of an automobile cab, in particular to an integrated electronically controlled reversing oil pump. Background technique [0002] The oil pump is a light and compact pump, which can be divided into three categories: inline type, distribution type and single type. The oil pump needs a power source to run, and the camshaft at its lower part is driven by the crankshaft gear of the engine. [0003] Oil pump An oil pump is proposed having a housing made of an aluminum-containing material and a movable molded part arranged in the housing, wherein the movable molded part is at least partially made of a sinterable, is made of a material comprising at least one austenitic iron-based alloy, and wherein the molding made of a sinterable material has a coefficient of thermal expansion that is at least 60% of the coefficient of thermal expansion of the housing. [0004] At present, the cab li...
