The present invention relates to an improvement of a lever for intermittently controlling the connection of a starting motor and a drive shaft in a starting motor assembly of an automobile.

The starting mechanism of the vehicle is arranged in close proximity to the starting motor and the drive shaft, and interrupts the end shaft of the starting motor by a lever connected to the solenoid to transfer or short circuit the starting power.

In a conventional starter motor assembly, a roughly symmetrical lever dynamically connects the end of the rotary shaft of the starter motor in the housing and the drive end of the solenoid on one side of the starter motor to transfer power.

The present invention is to improve the lever in order to reduce the errors occurring during the assembly process due to the shape of the conventional lever in the assembly of the starter motor assembly.

In the conventional starter motor assembly of FIG. 1, a starter motor M (not shown) is mounted in the housing 1, and an operating solenoid 2 is installed above and a starter shaft end 6 of the starter motor M. ), And the drive shaft 7 is fitted in a straight line, and the lever is between the retainer portion 3 'at the end of the solenoid side 3 of the operation solenoid 2 and the retainer 6' at the start shaft end 6; (4) is connected.

The lever shaft 5 of the lever 4 is a plate-shaped body having a generally circular shape, and the circular lever shaft 5 is rotatably fitted in the space of the shaft retainer 8 formed by the housing 1 being assembled. .

2 is a cross-sectional view taken along line A-A showing the lever shaft 5 of FIG. 1 in more detail.

In the conventional lever 4, as shown in FIG. 2, the lever shaft 5 protrudes at both ends, and the protrusion 9 is fitted freely in the shaft retainer 8 formed by the housing 1. The lever 4 converts the linear movement of the actuating solenoid 2 into the connection short movement of the starting shaft end 6 to the drive shaft 7 with the lever shaft 5 as the point.

The conventional lever 4 has a circular body of the same shape and size as the glacier shown in FIG. 2, with the protrusions 9 on both sides of the lever side 5 being the same shape and size (ie C = F, D = E). Since the shape is similar, the assembler can assemble the assembly as opposed to the normal insertion direction, and even if assembled in such a state, there is no interference member in the housing. In order to do this, there is a problem that the whole assembly process must be repeated, which has greatly affected the productivity.

The lever of the present invention is formed so that the assembly is not made when inserting in the opposite direction from the beginning by changing the size of the left and right protrusions 9 of the lever shaft 5 to eliminate this problem.

3 to 5 show the lever of the present invention.

The same member as the prior art uses the same member number.

The protrusions 19 and 19 'of both ends of the lever shaft 15 of the lever 14, which are almost the same shape as the conventional lever 4, have a circular shape so as to facilitate a rotational movement in the shaft retainer and the protrusions 19 ) And the protrusions 10 'have a slight difference from each other. In other words, G J and H I.

5 is a front view showing this lever shaft 15.

The lever 14 of the starting motor assembly of the present invention is a useful design that can eliminate the conventional problem because the misassembly is eliminated at the source because it is not fitted to the contrary at the time of assembly.

Claims (1)

Retainer portion 3 'at the end of the starting shaft end 6 of the starting motor M and the solenoid shaft 3 of the actuating solenoid 2 and the retaining portion of the starting shaft end 6 in the housing 1. In the lever of the starter motor assembly having a lever shaft (5 ') rotatably fitted in the space of the bearing retainer (8) as a plate-shaped frame having a generally circular shape, and which is connected to each other. The protrusions 19 and 19 'of both ends of the lever shaft 15 have a circular shape so that the rotational movement is smooth in the bearing retainer 8, and the diameters of the protrusions 19 and the protrusions 19' are different from each other. The lever of the starting motor assembly characterized by.
