Vehicle idle-speed stepping motor provided with sealing sleeve

Abstract

The invention provides a vehicle idle-speed stepping motor provided with a sealing sleeve, which comprises a vehicle idle-speed stepping motor base, a pivot pin socket, a compression spring, a plastic sealing sleeve, a pivot pin and an electric wire socket. The vehicle idle-speed stepping motor is characterized in that, the pivot pin socket is arranged at the middle part of the top of the vehicle idle-speed stepping motor base. The bottom of the plastic sealing sleeve is embedded inside the pivot pin socket. The compression spring is sleeved onto the inner cavity part of the plastic sealing sleeve, and the diameters of the compression spring and the inner cavity part of the plastic sealing sleeve are matched with each other. The pivot pin passes through the plastic sealing sleeve and the cavity part of the compression spring to be in threaded connection with the vehicle idle-speed stepping motor base, so that a vehicle is ensured to run more stably. The service life of the vehicle idle-speed stepping motor is prolonged and other linkage parts in the engine of the vehicle are effectively protected. The vehicle idle-speed stepping motor is suitable for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the field of automobile parts, in particular to an idle motor of an automobile stepping motor provided with a sealing sleeve. Background technique [0002] The idle speed motor of the automobile stepper motor is the main driving component of the automobile at idle speed, and it is also a more precise part in the vehicle. Its normal and stable operation is related to the operation safety of the entire vehicle. At present, the known idle speed motor of the automobile stepper motor Among them, the gap of the shaft pin socket is relatively large, and some metal tubes are set on the shaft pin to prevent the dust from falling in, but when the automobile stepper motor is running at idle speed, the reciprocating motion of the shaft pin will remove the carbon deposits in the filter element. And dust is easy to be brought into the idle motor of the stepping motor of the car, so that the deposition inside the idle motor of the stepping mo...

[0002] The idle speed motor of the automobile stepper motor is the main driving component of the automobile at idle speed, and it is also a more precise part in the vehicle. Its normal and stable operation is related to the operation safety of the entire vehicle. At present, the known idle speed motor of the automobile stepper motor Among them, the gap of the shaft pin socket is relatively large, and some metal tubes are set on the shaft pin to prevent the dust from falling in, but when the automobile stepper motor is running at idle speed, the reciprocating motion of the shaft pin will remove the carbon deposits in the filter element. And dust is easy to be brought into the idle motor of the stepping motor of the car, so that the deposition inside the idle motor of the stepping motor of the car will hinder its normal operation, and also shorten the service life of the associated precision components such as the air filter, so how can it be Improving the sealing performance of the idle motor of the automobile stepper motor has always been a technical problem that plagues the industry. The present invention has carried out a novel invention around the above technical problem
