Problems solved by technology

Therefore, when the shift fork 9 drives the driving gear element 6 to move forward, a part of the matching spline part on the output shaft 5 will be exposed, which makes this part of the matching spline part (especially the lubricating grease on it) easy to be removed. get dirty
[0009] In addition, since the entire driving gear member is made of metal, the inner end of the shift fork 9 will be worn when the driving gear member rotates

Embodiment Construction

[0035] Some preferred embodiments of the present invention are described below with reference to the accompanying drawings.

[0036] image 3 shows a drive gear assembly in a vehicle starter according to a preferred embodiment of the present invention, which can be used to replace figure 1 , 2 Drive gear element 6 shown in . Unless otherwise indicated, the preceding reference figure 1 , 2 The details described for the vehicle starter also apply to the following description of the invention.

[0037] As shown, the drive gear assembly of the present invention consists of a drive gear 20 and a generally cylindrical or circular fork drive member 40 attached to the rear of the drive gear in a hooked manner. Figure 4 The driving gear 20 is shown separately in Figure 5-7 The fork drive 40 is shown alone.

[0038] First of all, it should be pointed out that the so-called "rear" in this application is used to define the direction close to the side of the electric motor in the ...

Abstract

The invention discloses a vehicle starter and a drive gear assembly thereof. The drive gear assembly comprises a drive gear of metal and a shift fork drive member. The drive gear is provided with an axial through inner hole, and splines are formed in the inner hole. The shift fork drive member comprises an approximately cylindrical body and a gripping part disposed at the front end of the body. The shift fork drive member is attached to the rear end of the drive gear through the gripping part. The invention further discloses the vehicle starter comprising the drive gear assembly. The drive gear assembly has the advantage that the weight and cost can be reduced.

Description

technical field [0001] The present invention relates to a drive gear assembly for use in a vehicle starter and a vehicle starter comprising such a drive gear assembly. Background technique [0002] Modern vehicles usually use an electric starter to start the engine of the vehicle. The starter converts the electric energy stored in the battery of the vehicle into mechanical energy to drive the engine of the vehicle to start the engine. [0003] The starter is usually composed of an electric motor, a transmission mechanism and a control mechanism. figure 1 A part of a conventional vehicle starter is shown in , wherein an electric motor 1 is installed in a housing 2 of the starter for generating rotational torque. The rotational torque is transmitted to the ring gear (not shown) on the flywheel of the engine through the transmission mechanism to drive the crankshaft of the engine to rotate. [0004] The transmission mechanism mainly includes a reduction mechanism 3 connected ...
