Description
Technical field
The utility model relates to a kind of electric booster steering device device, especially a kind of circulating ball electric booster steering device that adopts novel sensor.
Background technology
Electric boosting steering system due to its have energy-efficient, low speed is light, high speed road feel is strong and the good advantages such as return performance, has now replaced traditional hydraulic power-assist steering system, be widely used in Vehicular turn.But electric boosting steering system is mainly used on car at present, and take rack and pinion steering gear as main.But for the cross-country car of driving on the complex road condition of being everlasting and all-terrain vehicle, ball-and-worm steering system is safer, reliable.
Original ball-and-nut steering gear is mechanical type circulating ball steering gear, and this type deflector does not have power-assisted, hard steering, and applicable vehicle is few.For improving hard steering problem, by mechanical type deflector, develop into hydraulic power assisted ball-and-nut steering gear, this deflector is power resources by Hydraulic Pump, has realized servo-steering function.But along with the requirement of energy-conserving and environment-protective, develop into circulating ball electric booster steering device.This type power-assisted steering device not only can be realized power steering, the more important thing is its energy-saving and environmental protection, non-maintaining, long service life and the features such as convenience are installed.
What existing circulating ball electric booster steering device adopted is the torque sensor of contact, and than non-contact torque sensor, this type power-assisted steering device is short service life, and reliability is relatively poor.And existing circulating ball electric booster steering device do not adopt modular design, installation and adjustment inconvenience, production efficiency is low.
Summary of the invention
The object of the invention is to: realize that a kind of loss is low, the circulating ball electric booster steering device of long service life, novel sensor that reliability is high, not long for improving service life of current circulating ball electric booster steering device, reliability is not high, and the problems such as difficulty are installed.
As utility model, improve, the utility model has adopted following technical scheme to be: the outer survey ring of novel Non-contact torque sensing device is fixed on reducer shell, its magnetic guiding loop is fixed on output shaft, and its magnet ring is fixed on input shaft, and input shaft is connected by torsion bar with output shaft.When input shaft rotates, output shaft also rotates with input shaft with respect to Torsion rod, because of Torsion rod, makes magnetic guiding loop the variation of magnet ring magnetic flow be detected, and this variation is delivered to outer survey ring, with the form of voltage signal, is transported to controller.
Compared with prior art the beneficial effects of the utility model are: this torque sensor is a kind of non-contact torque sensor.This type sensor construction is simple, easy for installation, and the outer ring of surveying adopts integrated chip to magnetic flux change simultaneously, and antijamming capability is strong, is convenient to installation and adjustment.Owing to adopting novel noncontacting proximity sensor, sensor is realized signal lossless transmission, has greatly improved circulating ball electric booster steering device service life.
As utility model, improve, the utility model adopts another technical scheme to be: this utility model has adopted modular design, take the module one that novel Non-contact torque sensing device, worm and gear and reducer shell be core, take the module two that circulating ball housing and tooth fan be core.Module one forms and comprises other appurtenances such as non-contact torque sensor, worm and gear input shaft, steering fan, reducer shell.Module two forms and comprises other appurtenances such as circulating ball housing and tooth fan.
Compared with prior art the beneficial effects of the utility model are: adopt modular design, simplicity of design, facilitates the application of different automobile types circulating ball electric booster steering device, are convenient to produce simultaneously and install.
Accompanying drawing explanation
Accompanying drawing is the constructional drawing of the circulating ball electric booster steering device of novel sensor.
In accompanying drawing: 1 is input shaft, 2 is magnet ring, and 3 is magnetic guiding loop, 4 is outer survey ring, and 5 is worm screw, and 6 is reducer shell, 7 is output shaft, and 8 is torsion bar, and 9 is steering screw, 10 is circulating ball housing, and 11 is bearing, and 12 is bolt, 13 is roller bearing end cap, and 14 is tooth fan, and 15 is bearing, 16 is worm gear, and 17 is bearing, and 18 is bearing.
The specific embodiment
The utility model module one: outer survey ring (4) and worm screw (5) are installed in reducer shell (6).Input shaft (1) is connected with magnet ring (2), magnetic guiding loop (3), worm gear (16) and bearing (17) press-fit in turn in output shaft (7), input shaft (1) is connected by torsion bar (8) with output shaft (7), and rear output shaft (7) is fixedly connected with by pin with steering screw (9), connects body and be installed in reducer shell (6).Wherein connector is supported by bearing (18) and bearing (15), and worm and gear is realized effectively engagement simultaneously.
The utility model module two: roller bearing end cap (13), tooth fan (14) and appurtenances are installed in circulating ball housing (10).
Module one is assemblied in module two.Steering screw and tooth fan are realized effectively engagement, and module one is bolted and is connected with module two.
When input shaft (1) has steering effort, between input shaft (1) and output shaft (7), there is torque difference, make torsion bar (8) that deformation occur, magnet ring (2) on input shaft (1) relatively rotates with the magnetic guiding loop (3) on output shaft (7), cause the magnetic flow on magnetic guiding loop (3) to change, this magnetic energy variable quantity is passed to outer survey ring (4), and outer survey ring (4) converts magnetic energy signal to electric signal, delivers to controller.
