Abstract
The utility model relates to the technical field of machines, in particular to a rack of a servotronic machine. The rack of the servotronic machine comprises a rack body and a toothed structure, wherein the upper side of the right part of the rack body is provided with the toothed structure. Compared with the prior art, a simple structure is adopted by the rack of the servotronic machine, and thus, when a car runs at a low speed, the assistance of a steering wheel is large and the steering wheel is lighter, so that the steering wheel is flexible in operation, whereas when the car runs at a high speed, the assistance of the steering wheel is small, and the steering wheel is heavier, so that the car stably runs, and the steering wheel can be easily controlled.
Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of tooth bar with fast steering box.
Background technology
Now, all used servo-steering on the nearly all car.Servo-steering has a variety of, and oldfashioned is immutable servo-steering, also claims the mechanical type steering swivel system, is to rely on the steering effort of pilot control bearing circle to realize wheel steering, and general economy car uses the many of mechanical-hydraulic force aid system.Another kind is the changed servo-steering with engine speed change, and this power steering system can make handling maneuver more flexible, light than the former.But; Can change power-steering major defect is: if the power steering system that designs is in order to reduce the power of automobile steering wheel rotation under parking or low speed driving state; Then when the automobile at high speed goes; This power steering system can make the power of steering wheel rotation seem too little, is unfavorable for the automobile travel direction control to running at high speed; Otherwise if institute's design-calculated power steering system is in order to increase the steering effort of automobile when running at high speed, then when automobile stagnation of movement or low speed driving, it is very painstaking that steering wheel rotation will seem.Therefore, design a kind of can be when the automobile low speed driving bearing circle power-assisted big, the little tooth bar with fast steering box of bearing circle power-assisted is vital during at galloping.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art, provide a kind of can be when the automobile low speed driving big, the little tooth bar of bearing circle power-assisted during at galloping of bearing circle power-assisted with fast steering box.
In order to achieve the above object, the utility model has designed a kind of tooth bar with fast steering box, comprises tooth bar body and toothing, it is characterized in that: the right part upside of tooth bar body is provided with toothing.
The utility model is compared with prior art, adopts simple structure, and the bearing circle power-assisted is big when the automobile low speed driving, and bearing circle is low weight, makes the bearing circle flexible operation; And the bearing circle power-assisted is little when galloping, and bearing circle is heavier, makes vehicle ' steady, and bearing circle is easy to grasp.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Referring to Fig. 1,1 is the tooth bar body; 2 is toothing.
The specific embodiment
Combine accompanying drawing that the utility model is done further describes at present.
Referring to Fig. 1, the utility model comprises tooth bar body and toothing.The right part upside of tooth bar body 1 is provided with toothing 2.
The utility model adopts the toothing 2 of variable ratio, makes automobile bearing circle power-assisted when low speed driving big, and bearing circle is low weight, makes the bearing circle flexible operation; And automobile bearing circle power-assisted when running at high speed is little, and bearing circle is heavier, makes vehicle ' steady, and bearing circle is easy to grasp.
