Suspension lifting device suitable for new energy automobile

Abstract

The invention discloses a suspension lifting device suitable for a new energy automobile, and relates to the technical field of new energy automobiles. The suspension lifting device comprises a double-shaft motor, a speed reducer and a flange plate, and further comprises an upper sleeve, a lower sleeve, a shell, a buffer component, a fixing component, a linkage component, a lubricating component, a first screw rod, a first spring, a second spring, a driving gear, a driven gear, a first nut, a second nut and a disc. The double-shaft motor is fixedly arranged on one side of the upper sleeve, the speed reducer is arranged on an output shaft above the double-shaft motor, the buffer component is arranged on an output shaft of the speed reducer, the fixing component is arranged on the lower portion of the upper sleeve, a clamping groove is further formed in the lower portion of the upper sleeve, the driving gear is arranged at the end of an output shaft of the double-shaft motor, lubricating oil is sprayed more comprehensively when the first screw rod rotates, a second screw rod is effectively protected, thread slipping is prevented, abrasion is reduced, and potential safety hazards of a vehicle are avoided.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a suspension lifting device suitable for new energy vehicles. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as the power source, or the use of conventional vehicle fuels, the adoption of new vehicle power devices, and the comprehensive vehicle power control and advanced technology in driving, forming advanced technical principles and new features. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles and hydrogen engine vehicles. [0003] The Chinese invention patent with the publication number CN113103838A discloses a suspension lifting device suitable for new energy vehicles, including a housing, a base, a driving motor, a transmission mechanism and a first screw; the housing includes a fixedly connected upper housing and the lower casin...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned patent moves the base and the shell relative to each other by driving the motor, the transmission mechanism and the screw rod, thereby adjusting the height of the vehicle frame. During the height adjustment process, the height of both sides of the vehicle suspension is the same, and the force on the vehicle is balanced, but there are still the following problems: 1. In the absence of lubricating oil between the screw and the base, the device is prone to wear after working for a period of time, resulting in inconsistent lifting heights on both sides of the vehicle when the car is suspended on the lifting frame, which will affect the balance of the vehicle, and in more serious cases 2. The car suspension is fixed after the lifting and lowering is completed, and the rack and the locking pin are used to cooperate and insert and engage the limit. The fixed position of the device is very inaccurate, and the fixing effect is not good. When the vehicle is bumpy, it is easy to cause the latch to break away from the limit, resulting in suspension breakage, etc. In this case, the vehicle is prone to safety hazards
