Description
Technical field
The present invention relates to automobile chassis, and in particular to a kind of rack and pinion steering gear.
Background technology
Automotive steering is the mechanism for changing or keeping vehicle traveling direction, ensures that automobile can be by the will of driver
And carry out Turning travel.Steering assembly is the important component in automobile steering system, and common steering gear includes gear
Rack-and-pinion, cam and lever with fixed stud and circulating ball type.Rack and pinion steering gear is due to simple in construction, compact, transmission efficiency,
Using more in automobile.Because the frequency of use of the steering gear in vehicle traveling process is very high, and operating mode is complicated, easily produces different
Ring.Wherein, caused abnormal sound is particularly evident in tooth sector and steering rack engagement process, when tooth sector and steering rack are nibbled
When vibration frequency and steering assembly own frequency during conjunction approach or are identical, resonance can be produced, sends abnormal sound.Influence to use
The comfortableness of person, reduce vehicle quality.
The situation of steering assembly abnormal sound have it is a variety of, as disclosed in CN201210489929.6《A kind of automobile machinery turns
To the anti-abnormal sound structure of device》, it is by the O-shaped rubber of increase at the cooperation of rack support briquetting side wall and diverter body inner walls
Cushion rubber I and O-shaped rubber ring II, increase O-shaped rubber ring III at the end face cooperation of rack support block end face and gap adjustment nut,
Solve be steering gear rack support briquetting and diverter body housing between collide, rack support block end face and gap tune
The end face of section nut collide caused by abnormal sound problem；Disclosed in CN201620116345.8《Mounting bracket on steering column
Mode lift structure》, it is by being symmetrical arranged the two pieces of reinforcing plates in left and right in mounting bracket on steering column, reaching lifting steering column
The upper rigid effect of mounting bracket, steering wheel in vehicle traveling is avoided to be resonated with engine.Two patent documents do not have
Solves the problems, such as abnormal sound caused by being resonated when tooth sector engages with steering rack with steering assembly.
The content of the invention
It is an object of the invention to provide a kind of rack and pinion steering gear, its can suppress or eliminate due to tooth sector with
With abnormal sound caused by steering assembly resonance when steering rack engages, driver comfort and vehicle quality are improved；Simple in construction,
Connection is reliable.
A kind of rack and pinion steering gear of the present invention, including steering gear housing, the right side with the steering gear housing
The steering gear sleeve pipe for holding connection, the tooth sector being located in steering gear housing body, it is located at the steering gear housing and steering gear sleeve pipe
Steering rack that is interior and being engaged with the tooth sector, it is characterized in that：The outer surface of the steering gear sleeve pipe be connected with to
A few abnormal sound suppresses set, and is fastened by anchor ear.
Further, the abnormal sound suppresses to be provided with annular recess in the middle part of the outer surface of set, and the anchor ear suppresses with the abnormal sound
The annular recess put coordinates.
Further, the material that the abnormal sound suppresses set is rubber.
Further, the material that the abnormal sound suppresses set is preferably neoprene.
The beneficial technique effect of the present invention：
Due to being connected in the outer surface of steering gear sleeve pipe, abnormal sound suppresses set, can suppress set by adjusting abnormal sound
Material, quality, number, position, or change the cross sectional shape that abnormal sound suppresses set, the mode of steering assembly is adjusted, is made
Steering assembly mode engaged with tooth sector with steering rack caused by vibration frequency avoid, suppress or eliminate due to
Abnormal sound caused by resonance, improve driver comfort and vehicle quality；Simple in construction, connection is reliably.

Embodiment
The present invention is elaborated below in conjunction with drawings and examples.
Referring to a kind of rack and pinion steering gear shown in Fig. 1 and Fig. 2, including steering gear housing 1 and the steering gear housing
The steering gear sleeve pipe 2 of the right-hand member connection of body 1, the tooth sector 3 being located in steering gear housing 1, it is located at the and of steering gear housing 1
The steering rack 4 engaged in steering gear sleeve pipe 2 and with the tooth sector 3, its substantive distinguishing features protruded are：The steering gear
The outer surface of sleeve pipe 2 is connected with least one abnormal sound and suppresses set 5, and is fastened by anchor ear 6.Abnormal sound suppresses the use of set 5
The quality of steering assembly can be changed, adjust the mode of steering assembly so that the mode of steering assembly is with tooth sector 3
Vibration frequency caused by being engaged with steering rack 4 is avoided, and can be suppressed or be eliminated the abnormal sound caused by resonance, Neng Gouti
High driver comfort and vehicle quality.
The abnormal sound suppresses to be provided with annular recess in the middle part of the outer surface of set 5, and the anchor ear 6 suppresses on set 5 with the abnormal sound
Annular recess coordinate.Annular recess plays position-limiting action, can limit position when anchor ear 6 suppresses the cooperation of set 5 with abnormal sound, anchor ear
After 6 tighten, abnormal sound can be avoided to suppress set 5 and move axially or rotate on steering gear sleeve pipe 2.
The material that the abnormal sound suppresses set 5 is rubber.
The material that the abnormal sound suppresses set 5 is preferably neoprene.
During assembling, the outer surface that abnormal sound is first suppressed to set 5 and steering gear sleeve pipe 2 coordinates, and is then fastened with clip 6,
Simple in construction, connection is reliably.The screw rod screw-down torque of clip is 5-7N.m (newton rice), and abnormal sound can be avoided to suppress set 5 with turning
To axial movement between device sleeve pipe 2 or rotate.The mode of steering assembly can suppress the section shape of set 5 by changing abnormal sound
Shape or regulation abnormal sound suppress to cover the changes such as 5 material, quality, number, position；Abnormal sound suppresses the material and Shao Er of set 5
Hardness carries out matching determination according to vehicle mode；Abnormal sound suppresses the position of set 5 according to the progress of the mode of steering assembly
With determination.
Position includes：When it is one that abnormal sound, which suppresses set 5, regulation abnormal sound suppresses set center and steering gear housing right-hand member
The distance a in face can change the mode of steering assembly；When it is two or more that abnormal sound, which suppresses set 5, the different of high order end is adjusted
Ring between the distance a for suppressing set center and steering gear housing right side, or the two neighboring abnormal sound suppression set center of regulation
Distance b, it can change the mode of steering assembly.
For Ou Shang series vehicles, through experiment obtain abnormal sound inhibition it is optimal when abnormal sound suppress the parameter of set 5：Abnormal sound presses down
The number of system set 5 is two, uses Shao Er hardness to be made for 55-65 chloroprene rubber material, and each abnormal sound suppresses set 5
Quality is 55g or so, and the distance a that abnormal sound suppresses set center and steering gear housing right side is 25mm (millimeter), two neighboring different
It is 140mm (millimeter) to ring the distance between suppression set center b.Part vehicle can increase or decrease abnormal sound according to matching result
Suppress the quantity of set 5, set is such as suppressed using an abnormal sound, three abnormal sounds suppress set, four abnormal sounds suppress set.
