Abstract
The utility model discloses the damping structure of a rack-and-pinion steering engine, which comprises a shell. The shell is provided with a shell mounting hole. A damping rubber sleeve is arranged in the shell mounting hole. According to the technical scheme of the utility model, by means of the damping structure of the rack-and-pinion steering engine, the impact noise generated among spacing pieces is effectively avoided due to the extra adoption of the damping rubber sleeve in the shell mounting hole of the steering engine. Therefore, the driving comfort is improved.
Description
Technical field
The utility model relates to gear rack type steering engine, is specifically related to gear rack type steering engine shock-damping structure.
Background technology
At present, in pinion and-rack hydraulic power-assisted steering machine, the steering box of prior art and the connecting mode of subframe are Bolt Connection, belong to rigid attachment.Conventional confguration, due to connecting mode reason, has the following disadvantages: 1, because housing and subframe are all metallic materials, therefore when chassis and steering swivel system, any one exists gap can cause abnormal sound.2, when car load travels in the time jolting road surface, when the axial force difference that is subject at two ends wheel is excessive, will cause torsion bar distortion, input shaft and gear position limiting place will interfere, and cause the generation of abnormal sound.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of in the time that chassis and steering swivel system exist gap, can avoid the gear rack type steering engine shock-damping structure of abnormal sound generation.
To achieve these goals, the technical solution adopted in the utility model is:
This gear rack type steering engine shock-damping structure, comprises housing, is provided with housing mounting hole on described housing, in described housing mounting hole, is provided with yielding rubber cover.
Described yielding rubber cover is fitted on described housing mounting hole inwall.
Described yielding rubber cover is injection molded into integrative-structure by rubber outer ring, injection molded elastomer layer and rubber inner ring.
On described yielding rubber cover end face, be provided with groove.
Described groove is located on described injection molded elastomer layer.
Described groove is symmetrically distributed on described injection molded elastomer layer.
The utility model has the advantage of: this gear rack type steering engine shock-damping structure, first, by increasing yielding rubber cover on the mounting hole at steering box housing, effectively avoid the impact noise between limit element, improve driver comfort.Secondly, on this yielding rubber cover end face, be with flutedly, effectively avoided the shearing that compressive deformation causes in the time press-fiting.Finally, this yielding rubber cover has effectively been avoided travelling in the time jolting road surface when car load, and when the axial force difference that is subject at two ends wheel is excessive, torsion bar is out of shape, the interference at input shaft and gear position limiting place, the abnormal sound causing.
Accompanying drawing explanation
Mark in content and the figure below each width accompanying drawing of the utility model specification sheets being expressed is briefly described:
Fig. 1 is the structural representation of the utility model gear rack type steering engine shock-damping structure.
Fig. 2 is the structural representation of the utility model and prior art middle gear rack steering engine housing.
Mark in above-mentioned figure is:
1, housing, 2, housing mounting hole, 3, yielding rubber cover, 4, groove.
The specific embodiment
Contrast accompanying drawing below, by the description to optimum embodiment, the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, this gear rack type steering engine shock-damping structure, comprises housing 1, is provided with housing mounting hole 2 on housing 1, is provided with yielding rubber cover 3 in housing mounting hole 2, and preferably yielding rubber cover 3 is fitted on the inwall of housing mounting hole 2.
Yielding rubber cover 3 is injection molded into integrative-structure by rubber outer ring, injection molded elastomer layer and rubber inner ring.
Overlap on 3 end faces and be provided with groove 4 at yielding rubber, groove 4 can effectively be avoided 3 shearings that compressive deformation causes in the time press-fiting of yielding rubber cover.
Preferably groove 4 is located on injection molded elastomer layer.
Preferably groove 4 is symmetrically distributed on injection molded elastomer layer, and preferably groove 4 is two.
Yielding rubber cover 3, effectively having avoided chassis and steering swivel system there is gap and causes abnormal sound in any one, has improved driver comfort.The yielding rubber cover 3 increasing, has also avoided travelling in the time jolting road surface when car load simultaneously, and when axial force difference that two ends wheel is subject to is excessive, torsion bar is out of shape, and input shaft and gear position limiting place will interfere, and cause the generation of abnormal sound situation.
Test figures shows: use the incidence of the steering box abnormal sound of above-mentioned new construction to be far smaller than the steering box of existing structure, finally after passing through the fatigue test of steering box, the all technical of steering box all meets the requirements, adopt the steering box of new construction of the present invention to complete the examination of client road simultaneously, and entrucking in batches, prove that this scheme meets operating needs completely.
The utility model specific implementation is not subject to the restrictions described above, as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out, all within protection domain of the present utility model.
