Description

Technical Field

[0001] This utility model belongs to the field of automotive technology and relates to an integrated motor pump. Background Technology

[0002] The car chassis is equipped with a hydraulic system for chassis adjustment. The hydraulic system is driven by an electric motor pump.

[0003] Electric motor pumps typically consist of two motor housings on the left and right, and an electrical control housing on top of the two motor housings. The two motor housings and the top electrical control housing are sealed with sealant. However, the sealant application process is complex, and the sealant cannot be reused. Each time the pump is disassembled, it must be thoroughly cleaned before applying new sealant. Furthermore, the sealant easily flows onto the surface of the housing, requiring wiping and other cleaning work. Since the sealant is liquid, a sealing test must be performed after the entire pump is assembled, only after the sealant has dried, which affects the working cycle and reduces work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated motor pump that can solve the above-mentioned problems, and has a high degree of integration, is easy to disassemble and assemble, and has a good sealing effect.

[0005] According to the technical solution provided by this utility model: an integrated motor pump includes a first motor and a second motor connected to each other. The first pump is installed on the outside of the first motor, and the second pump is installed on the outside of the second motor. An electronic control unit is installed on the upper part of the first motor, and the electronic control unit is connected to the first motor and the second motor through wires. The first motor includes a first motor housing, and the first motor housing has a connected electronic control cavity and a first motor cavity from top to bottom. The top of the electronic control cavity is sealed with a cover. The two ends of the first motor cavity are a first pump connection port and a main connection port. The second motor includes a second motor housing, and the second motor housing has a second motor cavity. The two ends of the second motor cavity are a second pump connection port and a secondary connection port.

[0006] As a further improvement of this utility model, the first pump connection port has a flange structure.

[0007] As a further improvement of this utility model, the main connection port and the auxiliary connection port are equipped with flange structures.

[0008] As a further improvement of this utility model, the second pump connection port has a flange structure.

[0009] As a further improvement of this utility model, a motor seal is provided between the first motor and the second motor.

[0014] As a further improvement of this utility model, the output ends of the first motor and the second motor extend into the first pump and the second pump, respectively.

[0015] The positive and progressive effects of this application are as follows:

[0016] In this utility model: 1. The first motor housing integrates the motor cavity and the electrical control cavity, reducing the number of housings from three to two in the prior art, thus eliminating one complex sealing structure; 2. The first motor housing and the second motor housing are connected in a detachable manner, which is convenient for disassembly and has a simple structure; 3. The sealing of the first motor housing and the second motor housing is achieved by a sealing element, which can be a circular or rectangular sealing ring or other unrestricted shapes, and the sealing is simple and reliable; 4.
