Abstract
The utility model discloses a connecting transmission device for an electric power-assisted steering motor, which comprises a motor and an electric power-assisted steering mechanical transmission device. A concave claw or a convex claw is fixedly connected at the end of an output shaft of the motor, and is connected with the convex claw or the concave claw on the electric power-assisted steering mechanical transmission device in a transmission manner. A rubber sleeve is arranged between the concave claw and the convex claw, and is connected with the concave claw after being sheathed on the convex claw. The connecting transmission device for the electric power-assisted steering motor leads to stable running, does not have abnormal steering sound, and has long service life.
Description
Technical field
The utility model relates to a kind of connection transmission device, specifically relate to the transmission device that the automobile electric power-assisted steering motor connects with the electric power steering transmission system.
Background technique
The motor of the vehicle electric power-assisted steering device of domestic production at present is splined or the connection of biconvex pawl with connecting of system, more than these two kinds of transmission devices in use have following shortcoming:
Splined: because there is error in the external splines of internal spline on the motor and docking part when processing and installation, cause the coaxality and the error of perpendicularity after motor and system assemble relatively poor, so that motor is in operation and has the holding phenomenon, the infringement that also brings to bearing simultaneously makes motor produce abnormal sound and reduction of service life, causes the electric power steering motor to lose efficacy in advance.
The biconvex pawl connects: because the frequent commutation of electric booster steering device and the power of transmission is the transmission by rubber pad, thereby make the stressed compressive strain outward of rubber pad, to such an extent as to the gap between rubber pad and pawl increases, cause steering reaction hysteresis and small angle to turn to abnormal sound.
Summary of the invention
The purpose of this utility model provides a kind of running abnormal sound that steadily, do not commutate, and the electric booster steering device of long service life connects transmission device.
The technical solution of the utility model is, a kind of electric power steering motor connects transmission device, comprise motor and electric power steering mechanical transmission, the output axle head of described motor is fixedly connected with recessed pawl or dog, the dog or the recessed pawl that have on recessed pawl or dog and the electric power steering mechanical transmission are in transmission connection, between recessed pawl and dog, have rubber sleeve, be in transmission connection with recessed pawl after rubber sleeve is sleeved on the dog.
Described recessed pawl and dog have draw-in groove and the claw more than three or three respectively.
Described recessed pawl and dog have four draw-in grooves and claw respectively.
After adopting said structure, owing between recessed pawl and dog, have the rubber sleeve of being equipped with, rubber sleeve is sleeved on the dog transmission that cooperatively interacts of back and recessed pawl, make it into as a whole, rubber sleeve is wrapped between dog and the recessed pawl, is not easy to run out of, and can effectively improve the connection reliability of operation, and the noise of reduction motor, increase the service life.

Fig. 2 is the assembly structure schematic representation of the recessed pawl of the utility model, rubber sleeve and dog;
Fig. 3 is the assembly structure explosive view of the recessed pawl of the utility model, rubber sleeve and dog;
Fig. 4 is the assembly structure explosive view of the recessed pawl of another embodiment of the utility model, rubber sleeve and dog.
Embodiment
Below contrast accompanying drawing,, the utility model made further specifying by the description of embodiment.
Shown in Fig. 1～4, a kind of electric power steering motor connects transmission device, comprise motor 1 and electric power steering mechanical transmission 6, output shaft 2 ends of described motor 1 are fixedly connected with recessed pawl 3 or dog, the dog 5 or the recessed pawl that have on recessed pawl 3 or dog and the electric power steering mechanical transmission 6 are in transmission connection, between recessed pawl 3 and dog, have rubber sleeve 4, be in transmission connection with recessed pawl 3 after rubber sleeve 4 is sleeved on the dog 5.
Shown in Fig. 1～4, in order to make the effect of cooperatively interacting between recessed pawl 3 and the dog 5 tightr, transmit and can not subtract power, described recessed pawl 3 and dog 5 have draw-in groove 3-1 and the claw 5-1 more than three or three respectively, and recessed pawl 3 that the utility model adopted and dog 5 have four draw-in groove 3-1 and claw 5-1 respectively.
