Abstract
A kind of deflector supporting mechanism with shock absorption device, comprise housing assembly, gear, tooth bar and adjustment plug screw, gear, tooth bar and adjustment plug screw are positioned at housing assembly, wheel and rack is meshed, tooth bar abuts against on rack support seat, rack support seat is connected with adjustment plug screw, between rack support seat and adjustment plug screw, spring is installed, it is inner that spring is positioned at rack support seat, the two ends of tooth bar are fixedly connected with rod assembly respectively, it is characterized in that: be provided with tooth bar butterfly gasket between rod assembly and housing assembly end face.The utility model is when rod stroke is to two extreme positions, shock absorbing effect due to tooth bar butterfly gasket when pull bar end face and the left and right both ends of the surface of housing assembly are collided would not have abnormal sound to produce, decrease the wearing and tearing of equipment, and due to the little design and installation space that also can not take equipment of butterfly gasket distortion.
Description
Technical field
The utility model relates to technical field of automobile parts, is specifically related to a kind of deflector supporting mechanism with shock absorption device.
Background technology
Deflector to have people to drive with driverless operation and to have the mechanical device of propulsion source, makes its random device changing running route and direction in operational process.Rack and pinion steering gear is modal a kind of deflector, and its basic structure is a pair intermeshing miniature gears and tooth bar.When steering shaft drives miniature gears to rotate, tooth bar is moving linearly just.Sometimes, directly drive intermediate rod by tooth bar, wheel flutter just can be made to turn to.So this is the simplest deflector of one.The advantage of rack and pinion steering gear is, structure is simple, and with low cost, turn to sensitive, volume is little, directly can drive intermediate rod, is used widely on automobile therefore at present.
Steering gear rack is the important composition parts of rack and pinion steering gear, and many, conventional steering device rack support structure adopts supporting seat to include spring, and outside adjustment plug screw withstands spring to play the effect supporting tooth bar.Automobile, under more motoring condition, owing to the uncertain road conditions such as to jolt, produces supporting seat collision adjustment plug screw at rack support position, and rod stroke collides to two extreme position drag link end faces and housing or limit base, thus causes abnormal sound phenomenon.
Chinese patent authorized announcement date CN 202728323U, authorized announcement date is that the utility model on February 13rd, 2013 discloses a kind of rack and pinion steering gear for automobile steering system, comprise end cap, spring, elastic element, tooth bar bearing, tooth bar, gear, rack and pinion engagement below tooth bar bearing, be provided with spring between end cap and tooth bar bearing, the both sides of spring are provided with elastic element.
This utility model solves rack support position and the damping problem adjusting plug screw by arranging elastic element in spring both sides, but because its elastic element is O type circle, it does not have larger buffering damping capaicty, and pull bar end face and housing or limit base collide and cause the problem of abnormal sound not still to be solved.
Summary of the invention
The purpose of this utility model is the defect and the deficiency that overcome existing technology, provides that a kind of structure is simple, the deflector supporting mechanism of the band shock absorption device of little, the good damping effect of taking up room.
For realizing above object, technical solution of the present utility model is: a kind of deflector supporting mechanism with shock absorption device, comprise housing assembly, gear, tooth bar and adjustment plug screw, described gear, tooth bar and adjustment plug screw are positioned at housing assembly, described wheel and rack is meshed, described tooth bar abuts against on rack support seat, described rack support seat is connected with adjustment plug screw, between rack support seat and adjustment plug screw, spring is installed, it is inner that described spring is positioned at rack support seat, the two ends of described tooth bar are fixedly connected with rod assembly respectively, it is characterized in that: tooth bar butterfly gasket is installed between described rod assembly and housing assembly end face.
Described rack support seat is provided with rack support seat boss with adjustment plug screw contact position, and described rack support seat boss is provided with supporting seat butterfly gasket.
The outer ring place described tooth bar butterfly gasket being provided with butterfly gasket open slot tooth bar butterfly gasket is provided with butterfly gasket alice fillet structure.
The utility model compared to existing technology, has following advantage:
1, the utility model installs tooth bar butterfly gasket between rod assembly and the left and right both ends of the surface of housing assembly, when such rod stroke is to two extreme positions, shock absorbing effect due to tooth bar butterfly gasket when pull bar end face and the left and right both ends of the surface of housing assembly are collided would not have abnormal sound to produce, decrease the wearing and tearing of equipment, and due to the little design and installation space that also can not take equipment of butterfly gasket distortion.
2, the utility model installs supporting seat butterfly gasket on the supporting seat boss of rack support seat, does not have abnormal sound and produces, serve shock absorbing effect when rack support seat is collided with adjustment plug screw.
3, butterfly gasket is provided with open slot and alice fillet structure in the utility model, there is the butterfly gasket of open slot to play and avoid producing damaged effect because of tired, fin fillet structure can avoid elastic stress to concentrate, avoid butterfly gasket edge torn element simultaneously, improve element service life.

Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and with detailed description of the invention, the utility model to be described in further detail.
See Fig. 1, Fig. 3, Fig. 5, Fig. 6, a kind of deflector supporting mechanism with shock absorption device, comprise housing assembly 1, gear 2, tooth bar 3 and adjustment plug screw 4, described gear 2, tooth bar 3 and adjustment plug screw 4 are positioned at housing assembly 1, described gear 2 is meshed with tooth bar 3, described tooth bar 3 abuts against on rack support seat 5, described rack support seat 5 is connected with adjustment plug screw 4, between rack support seat 5 and adjustment plug screw 4, spring 6 is installed, it is inner that described spring 6 is positioned at rack support seat 5, the two ends of described tooth bar 3 are fixedly connected with rod assembly 7 respectively, between described rod assembly 7 and housing assembly 1 end face, tooth bar butterfly gasket 8 is installed, described tooth bar butterfly gasket 8 is provided with butterfly gasket open slot 11, the outer ring place of tooth bar butterfly gasket 8 is provided with butterfly gasket alice fillet structure 12.
