Abstract
The utility model relates to an electric power-assisted steering gear for minicars, which comprises an electromotor and a worm, and one end of the worm is connected with an output shaft of the electromotor through quincuncial elastic couplings. When the steering wheel of a driven car is rotated to the left and the right, the electric power-assisted steering gear cannot emit abnormal sound or bring slight fluctuating handle to a driver as well.
Description
Technical field
The utility model relates to the parts among the automobile EPS (electric boosting steering system), particularly a kind of mid-get car electric booster steering device.
Background technology
Electric booster steering device is the parts among the EPS (electric boosting steering system) of automobile; Include electrical motor and worm screw; The output shaft of worm screw one end and electrical motor connects through the mode of spline, and this kind splined mode can make between worm screw and the motor output shaft and have certain clearance.When steering vehicle left-right rotation bearing circle, because the power-assisted that commutates about electrical motor, the existence in this gap can cause navigating mate to produce the feel of slight fluctuations, if excessive clearance, power-assisted steering device also possibly produce the abnormal sound phenomenon, thus the traveling comfort that influence is driven.
Summary of the invention
The purpose of the utility model provides a kind of mid-get car electric booster steering device, when steering vehicle left-right rotation bearing circle, can not make the feel of navigating mate generation slight fluctuations, and this power-assisted steering device can not produce abnormal sound yet.
The said mid-get car electric booster steering device of the utility model comprises electrical motor and worm screw, and worm screw one end connects with motor output shaft, and worm screw one end connects with motor output shaft through quincunx elastic coupling.
The utility model is owing to adopt quincunx elastic coupling that worm screw is connected with motor output shaft; Not only can make between worm screw and the motor output shaft connect reliable; But also can eliminate the gap between worm screw and the motor output shaft fully, so when steering vehicle left-right rotation bearing circle, the switching-over power-assisted can not make navigating mate produce the feel of slight fluctuations about electrical motor; And power-assisted steering device can not produce abnormal sound yet, has guaranteed the traveling comfort of driving.
Description of drawings
Combine accompanying drawing that the utility model is done further explain at present.
Fig. 1 is the coupled situation scheme drawing of worm screw and motor output shaft in the said mid-get car electric booster steering device of the utility model.
The specific embodiment
As shown in Figure 1, this mid-get car electric booster steering device comprises electrical motor 1 and worm screw 4, and worm screw 4 one ends connect with motor output shaft 2 through quincunx elastic coupling 3.
Claims (1)
1. a mid-get car electric booster steering device comprises electrical motor (1) and worm screw (4), and worm screw one end connects with motor output shaft (2), it is characterized in that: worm screw one end connects with motor output shaft through quincunx elastic coupling (3).
