Abstract
The utility model relates to a starter one-way part device for starting up or shutting down a motor, which consists of a casing, a retainer ring, a splined sleeve, a buffer spring, a protecting cover and the like and is characterized in that the buffer spring is in a tower structure, the retainer ring is slidingly connected with the splined sleeve, and the buffer spring is sleeved on the splined sleeve. When the buffer spring of the one-way part is compressed, each ring on the buffer spring can be in a sleeved state, thereby reducing axial space occupation of the buffer spring. Therefore, the space for the one-way part to move axially along an armature shaft is increased, thereby preventing the buffer spring from being compressed flat, and further guaranteeing the normal operation of the one-way part and a starter.
Description
Technical field
The utility model relates to a kind of start and stop motor starter motor one-way element device.
Background technique
Existing automobile starter motor one-way element device, it is characterized by: it is made up of shell, collar 1, splined sleeve 2, damping spring 3, protecting cover etc.When magnetic switch was connected, collar 1 made one-way element move along the armature shaft direction under the effect of starter motor shift fork and slip ring, drove the engagement of actuation gear and flywheel.At this moment, damping spring 3 can move and is compressed with it, plays buffer function.As Fig. 1.
Its shortcoming is: the damping spring of one-way element is cylindrical helical arrangement, and each circle is the stack shape during compression.Owing to occupy certain space in the axial direction after the damping spring compression, so the starter motor shift fork just may occur when armature shaft moves at the driving one-way element, and damping spring is pressed and phenomenon, thereby cause damping spring to lose the effect of buffering, influence starter motor and flywheel stabilization, accurately engagement.
Summary of the invention
The purpose of this utility model is to provide a kind of start and stop motor starter motor one-way element device, and it has solved existing starter motor one-way element damping spring effectively and has been pressed problem also easily, has guaranteed one-way element and starter motor proper functioning.
The technical solution of the utility model is achieved in that start and stop motor starter motor one-way element device, form by shell, collar, splined sleeve, damping spring, protecting cover etc., it is characterized in that: damping spring is a pyramidal structure, collar and splined sleeve are slidingly connected, and damping spring is enclosed within on the splined sleeve.
Good effect of the present utility model is when the damping spring of one-way element is compressed, and each circle can be the fit state on the spring, has reduced damping spring axial space occupancy.Therefore, one-way element has just increased along the axially movable space of armature shaft, has prevented damping spring to be pressed situation also to take place, and then has guaranteed one-way element and starter motor proper functioning.
Description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 2, start and stop motor starter motor one-way element device, form by shell, collar 1, splined sleeve 2, damping spring 3, protecting cover etc., it is characterized in that: damping spring 3 is pyramidal structure, collar 1 is slidingly connected with splined sleeve 2, and damping spring 3 is enclosed within on the splined sleeve 2.
When magnetic switch was connected, collar 1 made one-way element move along the armature shaft direction sliding on splined sleeve 2 under the effect of starter motor shift fork and slip ring, drove the engagement of actuation gear and flywheel.At this moment, damping spring 3 can move and is compressed with it, plays buffer function.Because damping spring 3 be pyramidal structure, axial space takies lessly during compression, has increased the mobile space of one-way element, prevented that damping spring from being pressed and the situation generation.
