Abstract
The utility model relates to a transverse pull rod of a rack-and-pinion steering gear, which comprises three parts including an inner pull rod assembly, a front fastening adjusting nut and an outer pull rod. The inner pull rod assembly adopts a traditional pull rod structure; the front fastening adjusting nut is a standard piece; the rod body of the outer pull rod is a structure with a linear bending part and an arc-shaped bending part and differs from the traditional straight pull rod. The transverse pull rod has the advantages that a whole vehicle assembly process accords with the traditional pull rod, the bendy outer pull rod can effectively dodge a rim and a tire, and the traveling safety of vehicles is improved.
Description
Technical field
The utility model relates to the car chassis steering swivel system, is specifically related to the intermediate rod structure of rack and pinion steering gear.
Background technology
At present, in the automotive development process, vehicle safety has risen to unprecedented height.Chassis system has begun to adopt a large amount of electronic machines, comprises that ABS, ESP, EPS etc. are to improve vehicle safety.
The rack and pinion steering gear traditional line type intermediate rods that use little risk of the parts safety gaps such as existence and wheel rim, tire often in Vehicle Driving Cycle and steering procedure more, when Vehicular turn, especially the limit turns to, relative displacement can occur in wheel rim, tire and intermediate rod, wheel rim, tire move near pull bar, yet the linear pattern pull bar is dodged measure without self, thereby the gap between wheel rim, tire and intermediate rod is reduced.The version of the outside link assembly of linear pattern intermediate rod is also comparatively complicated, for guaranteeing outside link intensity, generally can make a lot of reinforced ribs on outside link.By optimizing the shape trend of outside link assembly, do a reverse radian at little interstitial site place and dodge, from mechanical design aspect lifting vehicle driving safety.
Summary of the invention
The purpose of this utility model is to provide a kind of rack and pinion steering gear intermediate rod, and this intermediate rod can be in the situation that do not change existing car load assembly technology, the safety gap of increase intermediate rod and wheel rim, tire, the driving safety of raising vehicle.
The technical solution of the utility model is as follows:
A kind of rack and pinion steering gear intermediate rod comprises draw-in bar assembly, prenex setting nut and outside link assembly three parts.The draw-in bar assembly comprises the draw-in bar body of rod and interior ball cap, and the outside link assembly comprises the outside link body of rod, outer ball cap and outer ball end; The outside link body of rod one end is connected with outer ball cap, and the other end is connected with the draw-in bar body of rod by prenex setting nut, ball cap in the draw-in bar body of rod other end connects by globosity, and outer ball end is arranged on outer ball cap; It is characterized in that: the described outside link body of rod is for straight line bending and the curved structure of radian, and the centre of sphere of the globosity of the centre of sphere of the globosity of outer ball end and draw-in bar rod end is all on the extended line of the axial line of the draw-in bar body of rod.
The described outside link body of rod and outer ball cap are integrated to forge and form.
The utility model becomes its body of rod into more practical, safer curved structure by traditional linear pattern design, has increased the gap between intermediate rod and wheel rim, tire, has improved the safety that car load travels and turns to.The general rate of project organization is high, can adapt to different automobile types.
Description of drawings
Fig. 1 is the schematic diagram of intermediate rod.
In Fig. 1, interior ball cap (1), the draw-in bar body of rod (2), prenex setting nut (3), the outside link body of rod (4), outer ball cap (5), outer ball end (6), wherein interior ball cap (1) and the draw-in bar body of rod (2) form draw-in bar assembly (7) jointly, and the outside link body of rod (4), outer ball cap (5) and outer ball end (6) form outside link assembly (8) jointly.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Referring to Fig. 1, this intermediate rod comprises draw-in bar assembly 7, prenex setting nut 3 and outside link assembly 8.
Its prenex setting nut 3 is gauge member, its type selecting should with the draw-in bar screw thread fit.
Its draw-in bar assembly 7 is consistent on version with traditional draw-in bar assembly, is the universal design of draw-in bar assembly, is comprised of the draw-in bar body of rod 2, interior bulb assembly two parts.The Main Differences of different draw-in bar assemblies is design depending on the car load operating needs of dimensions length, interior bulb pivot angle size etc.The draw-in bar body of rod 2 is designed to globosity near interior ball cap 1 end, bulb assembly in this structure and the common composition of interior ball cap 1, the draw-in bar body of rod 2 is designed to hexagonal structure near the medium position of the thread end of the prenex setting nut 3 of assembling and outside link assembly, is used for prenex the adjusting and uses.Wherein there is one section Design of Screw Thread interior ball cap 1 end, is used for whole intermediate rod is assemblied in the tooth bar end of rack and pinion steering gear, jointly forms steering assembly and is used for car load general assembly assembling use.
Outside link assembly 8 comprises the outside link body of rod 4, outer ball cap 5 and outer ball end 6.The outside link body of rod 4 is designed to comprise place linear portion bending and a curved transitional structure of place's radian, linear portion bending angle and curved radian size all depend on safety gap requirement between intermediate rod and wheel rim, tire, but the centre of sphere that must guarantee the centre of sphere of the draw-in bar body of rod 2 end globositys and outer ball end 6 globositys is on the extended line of the axial line at the draw-in bar body of rod 2 places.Outside link assembly 8 coordinates with draw-in bar assembly 7 thread segment section all keeps the design of square processing positioning boss, is used for the outside link body of rod 4 processing location.Structurally, the outside link body of rod 4 and outer ball cap 5 are integrated to forge and form, and the outside link body of rod 4 has been cancelled the reinforcing rib design on traditional outside link body of rod, guarantee that by forging processing technology it uses required stretching and compression strength.
This intermediate rod be first with prenex setting nut 3 by Screw assembly on the draw-in bar body of rod 2 of draw-in bar assembly 7, and then with outside link assembly 8 by Screw assembly on draw-in bar assembly 7, complete assembling.
