Abstract

The invention discloses an automobile maintenance lifting machine directly driven by a frameless combined permanent magnet synchronous linear motor. The lifting machine comprises a platform seat and four lifting mechanisms rectangularly arranged on the platform seat; each lifting mechanism comprises a guide stand column, a screw and a load bearing bracket, the screw is installed in the guide standcolumn through a bearing, the load bearing bracket provided with a structure matched with a thread with the screw sleeves the screw and moves up and down along the guide stand column, and the lower end of the screw is provided with a chain wheel; the four lifting mechanisms are subjected to transmission through the chain wheels; and the screw of at least one of the four lifting mechanism is directly driven by the frameless permanent magnet synchronous motor. The automobile maintenance lifting machine directly driven by the frameless combined permanent magnet synchronous linear motor is simplein structure, high in efficiency and low in noise.

Description

technical field [0001] The invention belongs to the technical field of automobile maintenance equipment, and relates to an automobile maintenance lift, in particular to a frameless combined permanent magnet synchronous linear motor direct-driven automobile maintenance lift. Background technique [0002] Car lift refers to the car maintenance equipment used for car lifting in the car maintenance industry. Lifts play a vital role in vehicle maintenance and maintenance. Whether it is overhauled or minor repairs, it is inseparable from it. Since the 1990s, domestic lifts have gradually become popular. As my country's automobile With the increase in ownership, lifts, as an important tool for car maintenance, have also greatly increased their demand. At present, there are more and more types of car maintenance lifts, the functions are more and more perfect, and the structure is more and more complicated. However, the jacking device generally adopts the hydraulic push rod method, a...
