Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle suspension motor pump technology, and in particular to an integrated suspension motor pump. Background Technology
[0002] In modern automotive active suspension systems, the electric motor pump serves as the core power unit, and its performance directly impacts the suspension's dynamic response and vehicle stability. Existing integrated electric motor pump systems typically combine two electric motor pumps with an electronic control unit (ECU) to achieve a compact structure and integrated functions. However, these systems generally suffer from insufficient sealing performance. The numerous sealing interfaces between multiple housings increase the risk of seal failure, allowing external contaminants such as rainwater, dust, and oil to easily penetrate the system through weak seals, affecting the normal operation of the electric motor pumps and the stability of the ECU. Therefore, developing an integrated suspension electric motor pump system with a reliable sealing structure is crucial for improving the reliability and lifespan of suspension systems. Summary of the Invention
[0003] This invention provides an integrated suspension motor pump to solve the problem of insufficient sealing performance of traditional motor pumps mentioned in the background art.
[0004] The technical solution of this utility model is as follows: An integrated suspension motor pump, comprising: a first motor pump body, a second motor pump body, and a top cover; The first motor pump body has a first top cavity at the top and a first side cavity on one side. The side cavity opposite to the first motor pump body has a first side sealing surface, and the top surface of the first top cavity has a first top sealing surface. The second motor pump body has a second top cavity at the top and a second side cavity on one side. The side cavity opposite to the second motor pump body has a second side sealing surface, and the top surface of the second top cavity has a second top sealing surface. The bottom of the top cover is provided with a first bottom sealing surface and a second bottom sealing surface, and a control plate is provided in both the first top cavity and the second top cavity. The first motor pump body and the second motor pump body are axially connected, the first side sealing surface and the second side sealing surface abut against each other, the first bottom sealing surface abuts against the first top sealing surface, and the second bottom sealing surface abuts against the second side sealing surface.
[0005] Furthermore, a dividing strip is provided at the bottom of the top cover, the dividing strip is located between the first bottom sealing surface and the second bottom sealing surface, and the bottom of the dividing strip abuts against the top of the first top sealing surface and the second top sealing surface.
[0006] Furthermore, the top of the top cover is provided with heat dissipation fins.
[0007] Furthermore, high and low voltage connectors are provided on both sides of the top of the top cover.
[0008] Furthermore, threaded holes are provided on the outer periphery of the first side sealing surface and the second side sealing surface, and screws are connected to the threaded holes.
[0009] The beneficial effects of this utility model are: 1. Simple and reliable sealing: The housings of the two motor pumps are axially connected and each is independently sealed with the top cover, avoiding the situation of poor sealing at the interface that occurs when the housings of the two motors are sealed with the top cover at the same time.
[0010] 2. Precise control and efficient integration: Two separate control units are integrated to independently control the two motor pumps, reducing signal transmission distance and interference, and improving control accuracy and response speed.
[0011] 3. Compact structure and high space utilization: By sharing a top cover, two independent housings are eliminated, reducing axial space occupation. This mainly enhances the sealing and structural strength of the connection between the two motors. Attached Figure Description
