Abstract
The utility model discloses a kind of actuating unit of differential steering control setup, and the output shaft of motor is coaxially connected with worm end, and this worm and wheel engages, and worm gear is solidly set on worm-wheel shaft, and coaxial sleeve is equipped with an one-level gear on this worm-wheel shaft; Secondary gear and one-level gears meshing, this secondary gear and controllable capacity pump swash plate are coaxially solidly set on gear wheel shaft, and the two ends of worm screw, worm-wheel shaft and gear wheel shaft respectively by bearings on housing.This actuating unit drives controllable capacity pump swash plate by motor, worm and gear and gear, because the transmission of motor, worm and gear and gear is fixed, reliably, error is less, so just can the aperture of control variable pump swash plate effectively, and allow controllable capacity pump swash plate return meta, so just can overcome traditional drawing cable mechanism well can not make controllable capacity pump swash plate effectively return the defect of meta, and this actuating unit is automatically controlled, need not need manual control as original.
Description
Technical field
The utility model belongs to differential steering control field, specifically, particularly relates to a kind of actuating unit of differential steering control setup.
Background technology
Automobile steering system is the specialized agency for changing or keep vehicle heading, and its effect is in vehicle travel process, and the will according to chaufeur changes vehicle heading.According to the difference of steering mode, track can be divided into turn to the large class with differential steering two.
At present, in known differential steering vehicle, most employing mechanical type hydraulic power steering: the some mechanical of output is converted into hydraulic energy by steering variable pump by driving engine, by regulating rotary to the swash plate aperture on controllable capacity pump, hydraulic fluid flow rate is changed, be that mechanical energy exports to change speed gear box by steering motor by hydraulic energy transfer again, thus realize the function of differential steering.Wherein, steering column is mainly connected with controllable capacity pump swash plate by drag-line by the adjustment of swash plate aperture.But, because drag-line is long, and drag-line fatigue can cause its length variations, will make like this to adopt the mode of drag-line manipulation can not effectively allow steering variable pump swash plate return meta, thus cause vehicle can not straight-line travelling, can the problems such as starting resistance be increased when starting vehicle, chaufeur will be caused like this to require great effort when steering wheel rotation; In addition, during reversing, the turn direction of vehicle reality is contrary with the hand of rotation of bearing circle, affects car load handling.
Utility model content
Technical problem to be solved in the utility model is the actuating unit providing a kind of differential steering control setup, returns meta for effectively allowing controllable capacity pump swash plate.
The technical solution of the utility model is as follows: a kind of actuating unit of differential steering control setup, it is characterized in that: comprise motor (1) and secondary gear (6), wherein the output shaft of motor (1) is coaxially connected with worm screw (2) end, this worm and wheel (3) engages, and worm gear is solidly set on worm-wheel shaft (4), and coaxial sleeve is equipped with an one-level gear (5) on this worm-wheel shaft; Described secondary gear (6) engages with one-level gear (5), this secondary gear and controllable capacity pump swash plate (7) are coaxially solidly set on gear wheel shaft (8), and the two ends of worm screw (2), worm-wheel shaft (4) and gear wheel shaft (8) respectively by bearings on housing.
Adopt above technical scheme, this actuating unit drives controllable capacity pump swash plate (7) by motor, worm and gear and gear, because the transmission of motor, worm and gear and gear is fixed, reliably, error is less, so just can the aperture of control variable pump swash plate (7) effectively, and allow controllable capacity pump swash plate (7) return meta, so just can overcome traditional drawing cable mechanism well can not make controllable capacity pump swash plate effectively return the defect of meta, and this actuating unit is automatically controlled, manual control need not be needed as original.
As optimal design, spy is installed with a controllable capacity pump swash plate positions sensor (9) in the end of described worm-wheel shaft (4), during use, the detection signal of this controllable capacity pump swash plate positions sensor is fed back to control system, to control, to adjust the aperture of controllable capacity pump swash plate (7) further.
As preferably, described one-level gear (5) and secondary gear (6) are quadrant gear.Adopt said structure, under the prerequisite meeting transmission requirement, can one-level gear (5) and secondary gear (6) be done smaller, thus be convenient to arrange.
Beneficial effect: this actuating unit passes through motor, worm and gear and gear drive controllable capacity pump swash plate (7), due to motor, the transmission of worm and gear and gear is fixed, reliably, error is less, so just can the aperture of control variable pump swash plate (7) effectively, and allow controllable capacity pump swash plate (7) return meta, so just can overcome traditional drawing cable mechanism well can not make controllable capacity pump swash plate effectively return the defect of meta, and this actuating unit is automatically controlled, manual control need not be needed as original, so just overcome the defect of conventional confguration well, and structure of the present utility model is simple, easy to implement, there is good practicality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the lateral plan of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, 2, a kind of actuating unit of differential steering control setup, is formed primarily of motor 1, worm screw 2, worm gear 3, worm-wheel shaft 4, one-level gear 5, secondary gear 6, controllable capacity pump swash plate 7, gear wheel shaft 8 and controllable capacity pump swash plate positions sensor 9.Wherein, the output shaft of motor 1 is coaxially connected with worm screw 2 end, and this worm screw 2 often engages with worm gear 3, and worm gear 3 is solidly set on worm-wheel shaft 4, and certain worm gear 3 also can be made of one structure with worm-wheel shaft 4.On worm-wheel shaft 4, coaxial sleeve is equipped with an one-level gear 5, and this one-level gear 5 often engages with secondary gear 6, and one-level gear 5 and secondary gear 6 are quadrant gear, and secondary gear 6 and controllable capacity pump swash plate 7 are coaxially solidly set on gear wheel shaft 8.And, the two ends of worm screw 2, worm-wheel shaft 4 and gear wheel shaft 8 respectively by bearings on housing (not shown in FIG.), and the end of worm-wheel shaft 4 is installed with the controllable capacity pump swash plate positions sensor 9 of an outsourcing, this controllable capacity pump swash plate positions sensor 9 is for the aperture of detection variable pump swash plate.
The foregoing is only preferred embodiment of the present utility model; it is not restriction with the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
