Technical field
The utility model belongs to the electromagnetic switchgear technical field, relates to the buffer gear in a kind of automobile electromagnetic starting switch.
Background technology
Automobile starter comprises an electromagnetic starting switch, in automobile starting, electromagnetic starting switch can contact with the starter receiver of automobile, the larger active force that exists between the two, because the hardness ratio of starter receiver is larger, cause easily the damage of electromagnetic starting switch, have influence on the life-span of electromagnetic starting switch.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for existing technology, buffer gear in a kind of automobile electromagnetic starting switch is provided, technical problem to be solved in the utility model is by the buffering of buffer gear realization to starter receiver, thus the life-span of improving electromagnetic starting switch.
The purpose of this utility model can realize by following technical proposal:
Buffer gear in a kind of automobile electromagnetic starting switch, electromagnetic starting switch comprises a moving core assembly, it is characterized in that, this buffer gear comprises a pull bar, one end face of described moving core assembly offers cavity vertically, the rear portion of described pull bar is plugged in the described cavity, the front end of described pull bar has the connecting portion that can be connected on the starter receiver, is provided with between described pull bar and the moving core assembly to make pull bar produce vertically the backward back-moving spring of mobile trend.
In the buffer gear in above-mentioned a kind of automobile electromagnetic starting switch, the rear end of described pull bar has the gear edge, the collar extension place of described cavity is installed with back-up ring, described back-moving spring is arranged in the cavity, and the two ends of described back-moving spring are resisted against respectively on described gear edge and the described back-up ring.
In the buffer gear in above-mentioned a kind of automobile electromagnetic starting switch, the connecting portion of described pull bar front end comprises a pull head, has one section bore between described pull head and the bar body less than the neck of body or pull head.
In the buffer gear in above-mentioned a kind of automobile electromagnetic starting switch, the inside of described pull bar has a shrinkage pool, and described shrinkage pool runs through the rear end face of this pull bar.
In the buffer gear in above-mentioned a kind of automobile electromagnetic starting switch, described pull bar adopts nylon material to make.
The operation principle of this device is as follows: front end pull head and the starter receiver of pull bar contact, when electromagnetic starting switch and starter receiver are contacted, active force between the two is applied on the back-moving spring by pull bar, both are played the effect of buffering by the elastic force of back-moving spring, thereby reduce the active force between electromagnetic starting switch and the starter receiver, improve the life-span of electromagnetic starting switch.
Compared with prior art, advantage of the present utility model is as follows:
1, this device arranges back-moving spring and pull bar, and the elastic force by back-moving spring plays the effect of buffering to electromagnetic starting switch and starter receiver, thereby reduces the active force between electromagnetic starting switch and the starter receiver, the life-span of improving electromagnetic starting switch.
2, this device arranges gear edge and back-up ring, improves the stability of the connection between back-moving spring and the pull bar, prevents that back-moving spring from deviating from.
