Abstract
The invention discloses a steering gear structure for reducing a mechanical shock noise. The steering gear structure comprises an adjusting plug screw (1) and a rack pressure block (2); a return spring (3) is arranged between the adjusting plug screw (1) and the rack pressure block (2); the rack pressure block (2) is pushed by a rack (4); waveform spring sheets (5) are also arranged between the adjusting plug screw (1) and the rack pressure block (2); the waveform spring sheets (5) are sleeved outside the return spring (3); and two or more waveform spring sheets (5) form a parallel combined waveform spring when at least two waveform spring sheets (5) exist. The steering gear structure for reducing the mechanical shock noise with the special structure can reduce the impact noise between the rack pressure block and the adjusting plug screw, and can improve the return speed of the rack pressure block at the same time, so that the rack pressure block more quickly resets along with the rack, so as to reduce the shock noise in the process.
Description
Technical field
The present invention relates to the diverter structure in the automotive field, especially relate to a kind of diverter structure that reduces the physical shock noise.
Background technology
In the prior art, diverter structure structure shown in Figure of description 1 and accompanying drawing 2 that manned vehicle adopts, no matter be with hydraulic booster or the deflector of pure physical construction, its clearance adjustment mechanism all adopts the mature structure of adjusting plug screw, tooth bar briquetting and the pull back spring between the two.This kind structure can effectively play the compression deflector, dynamically eliminates gear---the effect in tooth bar gap.But this structure can often produce the noise of physical shock, namely when handling maneuver is carried out in deflector, it is mobile laterally that tooth bar is pushing away the tooth bar briquetting, after steering operation stopped, the tooth bar briquetting was back into the state that compresses tooth bar by pull back spring, under some condition of service, particularly when occuring in the situation about frequently turning to, just send the mechanical noise of metal bump in the tooth bar briquetting return process, thereby reduced the satisfaction of chaufeur, then reduced the traveling comfort of car load.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of diverter structure that reduces the physical shock noise for problems of the prior art, its objective is and reduce the frequency that mechanical noise occurs, improve chaufeur to the satisfaction of vehicle, improve the comfort property of car load.
Technical scheme of the present invention is that the diverter structure of this kind reduction physical shock noise comprises adjustment plug screw, tooth bar briquetting, and be provided with pull back spring between described adjustment plug screw and the tooth bar briquetting, the tooth bar briquetting is promoted by tooth bar, and also be provided with the wavy spring sheet between adjustment plug screw and tooth bar briquetting, the wavy spring sheet is sleeved on the outside of pull back spring.
Described wavy spring sheet has one at least.
When described wavy spring sheet has two at least, two and plural wavy spring sheet composition parallel combination wave spring.
Described parallel combination wave spring is punched parallel combination wave spring.
Or described parallel combination wave spring is Winding type parallel combination wave spring.
Diverter structure with this kind reduction physical shock noise of said structure has the following advantages:
1. the diverter structure of this kind reduction physical shock noise can reduce the tooth bar briquetting and adjust the noise that mutually clashes between the plug screw, can improve again simultaneously the return speed of tooth bar briquetting, reset so that the tooth bar briquetting is followed tooth bar more rapidly, further reduced the impulsive noise in this process.
2. the diverter structure of this kind reduction physical shock noise has increased substantially the anti-acoustic capability of product, on the almost not impact of cost of product, has good practical value simultaneously.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of prior art.
Fig. 2 is the part sectional view of structure shown in Figure 1.
Fig. 3 structural representation of the present invention.
Fig. 4 is the part sectional view of structure shown in Figure 3.
Fig. 5 is the rigidity schematic diagram of regulating mechanism.
In Fig. 1-5,1: adjust plug screw; 2: the tooth bar briquetting; 3: pull back spring; 4: tooth bar; 5: the wavy spring sheet.
The specific embodiment
By the combination of structure shown in Fig. 1-2 as can be known, diverter structure of the prior art can often produce the noise of physical shock, namely when handling maneuver is carried out in deflector, it is mobile laterally that tooth bar is pushing away the tooth bar briquetting, after steering operation stops, the tooth bar briquetting is back into the state that compresses tooth bar by pull back spring, under some condition of service, particularly when occuring in the situation about frequently turning to, just sent the mechanical noise of metal bump in the tooth bar briquetting return process, thereby reduce the satisfaction of chaufeur, then reduce the traveling comfort of car load.
Fig. 3 and Fig. 4 are structural representation of the present invention, by Fig. 3 and structure shown in Figure 4 in conjunction with as can be known, the diverter structure that this kind reduces the physical shock noise comprises adjustment plug screw 1, tooth bar briquetting 2, and adjust between plug screw 1 and the tooth bar briquetting 2 and be provided with pull back spring 3, tooth bar briquetting 2 is promoted by tooth bar 4, and also be provided with wavy spring sheet 5 between adjustment plug screw 1 and tooth bar briquetting 2, wavy spring sheet 5 is sleeved on the outside of pull back spring 3.
Wavy spring sheet 5 has one at least, can be one, also can be more.When wavy spring sheet 5 has two at least, two and plural wavy spring sheet 5 composition parallel combination wave springs.And the parallel combination wave spring is punched parallel combination wave spring; Or the parallel combination wave spring is Winding type parallel combination wave spring.The parallel combination wave spring of which kind of form does not affect its concrete result of use.
The specific works process is: when deflector was not operated, wavy spring sheet 5 all kept seldom measuring the gap with adjustment plug screw 1 and tooth bar briquetting 2, and this moment, pressuring action only depended on pull back spring 3 to realize; When deflector has steering operation, after tooth bar briquetting 2 is promoted by tooth bar 4, after at first eliminating original a small amount of gap between tooth bar briquetting 2, wavy spring sheet 5, the adjustment plug screw 1, the three comes in contact, this moment, wavy spring sheet 5 was compressed, after turning to end, wavy spring sheet 5 and pull back spring 3 combineds action, promoting tooth bar briquetting 2 resets, until tooth bar briquetting 2, wavy spring sheet 5, adjust plug screw 1 three and disengage, wavy spring sheet 5 is ineffective, and tooth bar briquetting 2 begins to only depend on pull back spring 3 effects to reset.
Fig. 5 is the rigidity schematic diagram of regulating mechanism.In whole process, the elastic deformation amount of wavy spring sheet 5 and the relation of spring stiffness are a kind of processes of stepped variable rigidity.
The diverter structure that this kind reduces the physical shock noise can reduce the tooth bar briquetting and adjust the noise that mutually clashes between the plug screw, can improve again simultaneously the return speed of tooth bar briquetting, reset so that the tooth bar briquetting is followed tooth bar more rapidly, further reduced the impulsive noise in this process.
