Description
Technical field
The utility model relates to motor turning field, and specifically, the utility model relates to a kind of worm steering gear.
Background technology
In prior art, turn to steering swivel system primarily of compositions such as steering handwheel, steering shaft, steering columns, the rotation of steering handwheel is become the swing of pitman arm or the straight reciprocating motion of rack shaft by deflector, and to the mechanism that steering force amplifies.Deflector is generally fixed on automobile chassis frame or vehicle body, steering force is by generally also changing transmission direction after deflector, the force and motion that deflector exports is passed to wheel (steering swivel) by steering gear, and makes left and right wheels carry out the mechanism deflected by certain relation.
By the difference of steerable energy, steering swivel system can be divided into manual steering system to unify the large class of power steering system two.The effect of steering system rotates steering handwheel by chaufeur, keeps as required or change vehicle traveling direction, and alleviating the labour intensity of chaufeur.
Automobile steering system is made up of steering gear and steering control mechanism two parts, and steering gear back lash is excessive is caused by wearing and tearing owing to assembling improper or parts between each parts of steering system.One, mechanical type hydraulic power steering system 1, mechanical hydraulic power steering system are generally made up of parts such as Hydraulic Pump, oil pipe, pressure flow hybrid control valve body, V-type drive belt, petrol storage tanks.2, no matter whether car turns to, and this cover system all will work, and when turning to greatly the speed of a motor vehicle lower, needs Hydraulic Pump to export larger power to obtain larger power-assisted.So also waste resource to a certain extent.Drive such car, time time especially, low speed is turned, think that direction ratio is more heavy, driving engine also compares sweat.Pressure again due to Hydraulic Pump is very large, also damages force aid system than being easier to.Also have mechanical type hydraulic servo steering system to be made up of Hydraulic Pump and pipeline and oil cylinder, be keep pressure, no matter the need of power steering, system is in running order always, and energy consumption is higher, and this is also a reason place in cost source.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of worm steering gear, and this device adopts worm screw assisted diversion, and steering operation is light, navigating mate rapid operation.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of worm steering gear, comprise steering booster, permanent seat, direction rotating shaft and universal-joint, the rotating shaft of described direction is hinged on one end of steering booster, steering booster is connected with car body by permanent seat, steering booster other end fixed-direction dish, it is characterized in that: also comprise worm steering device, one end of described worm steering device is connected with direction rotating shaft by universal-joint, and the other end of worm steering device is connected with steering track rod.
Preferably, described worm steering device comprises worm screw vertical pivot, worm screw transverse axis, housing and connecting rod, described worm screw vertical pivot is vertically placed in housing, worm screw transverse axis horizontal positioned, worm screw transverse axis is mutually vertical with scroll bar vertical pivot, the contact position of worm screw transverse axis and scroll bar vertical pivot is meshing by turbo tooth, and one end of connecting rod is enclosed within worm screw transverse axis, and the other end is connected with steering track rod.
Preferably, described worm screw transverse axis outer race has shell, and described shell is provided with adapter plate.
Preferably, described adapter plate is triangle, and the position at adapter plate three angles is provided with mounting hole.
Adopt the technical solution of the utility model, following beneficial effect can be obtained:
Worm steering gear of the present utility model, steering torque is conveyed to worm steering device through steering booster, direction rotating shaft, universal-joint by bearing circle, worm steering device conveys to propons goat's horn by steering track rod, thus realize the turning function of portable and stable, worm steering device realizes the deceleration transmission between worm screw vertical pivot and worm screw transverse axis by mechanical worm-drive principle, realize actv. turning rate, alleviate the application force to bearing circle simultaneously.
