Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
The utility model causes endplay to become large for the bearing of input shaft wearing and tearing due to deflector in existing technology and reduces driver to the satisfaction of vehicle and bring the problem of potential safety hazard, a kind of deflector is provided, as depicted in figs. 1 and 2, comprising: upper bearing sleeve 1, lower bearing sleeve 2, blanking cover 3, input shaft assembly 4 (comprising bearing of input shaft), input shaft housing 5, steering structure 6 and spring 7;
Wherein, described upper bearing sleeve 1, steering structure 6, lower bearing sleeve 2, spring 7 and blanking cover 3 are sheathed on described input shaft assembly 4 successively, described spring 7 is positioned at the confined space 8 of described lower bearing sleeve 2, blanking cover 3 and input shaft assembly 4 formation and in compressive state, described upper bearing sleeve 1 and lower bearing sleeve 2 are by described steering structure 6 and the indirect contact of described input shaft assembly 4;
Described input shaft housing 5 is sheathed on described upper bearing sleeve 1, lower bearing sleeve 2 and blanking cover 3.
The described deflector that the utility model embodiment provides by arranging the spring 7 in compressive state in the confined space 8 of lower bearing sleeve 2, blanking cover 3 and input shaft assembly 4 formation, improve endplay thus the play motion of the input shaft of control deflector, improve the response of deflector, the distortion of the abrasion loss of bearing of input shaft by spring 7 is made up, solves in prior art and reduce driver because the bearing of input shaft wearing and tearing of deflector cause endplay to become large to the satisfaction of vehicle and bring the problem of potential safety hazard; Spring 7 also can open the effect of certain energy-absorbing simultaneously; the impact of the generation of the axis of steering gear input shaft is also carried out energy-absorbing by the distortion of spring 7; also certain protective effect can be started like this to bearing of input shaft; reduce the damage of bearing of input shaft, increase the service life of bearing of input shaft.
The utility model embodiment comprises two kinds of situations, the first: as depicted in figs. 1 and 2, described steering structure 6 is circulating ball structure; Corresponding, described input shaft assembly 4 is provided with the groove matched with ball.
The second: described steering structure is rack structure; Corresponding, described input shaft assembly is provided with the gear coordinated with tooth bar.
Concrete, as depicted in figs. 1 and 2, for being threaded between described blanking cover 3 with described input shaft housing 5; And be rotatably connected by sealing member between described input shaft assembly 4, be fixedly connected with between described lower bearing sleeve 2; Described input shaft housing 5 is fixedly connected with being between described upper bearing sleeve 1 and lower bearing sleeve 2.
In order to extend the service life of spring and coordinate the motion of other associated components, as depicted in figs. 1 and 2, be free-running fit between described spring 7 and described input shaft assembly 4.
The utility model embodiment is by improving the axial support of steering gear input shaft, effectively improve input shaft because of bearing of input shaft and to wear and tear the endplay brought, namely deflector affects the input characteristic of deflector problem due to the endplay increase of bearing of input shaft wearing and tearing generation in use procedure is improved, improve the response of the input and output of deflector, thus improve the problem of steering gear input shaft play motion in rotation process.Separately, this programme is applicable on diverter structure dissimilar on automobile.
As depicted in figs. 1 and 2, furthermore, the utility model embodiment is out of shape by spring 7 and the wearing and tearing of bearing of input shaft is sponged, ensure that bearing of input shaft is unlikely to have an impact to the endplay of the input shaft of deflector because of wearing and tearing, this programme is adopted to need the improvement bearing of input shaft suitable according to the type of input shaft, so that this programme is applied on input shaft, namely adjustment bearing of input shaft and the relative position between relevant fit structure is needed, namely spring 7 arrangement space is reserved, and also need the size of supporting seat (blanking cover 3) and bearing of input shaft and spring 7 to match.
In this programme, bearing of input shaft and spring 7 need to carry out designing and selecting according to actual conditions, the endplay of the input shaft of deflector is controlled by adjustment spring force, the i.e. play motion of the rotation of control inputs axle, thus ensure that the input of driver can accurately be passed to wheel by deflector by deflector, react the intention of driver accurately, improve the response performance of deflector.
That is, this programme carrys out the size of controlling spring power by the diameter of the size of design bearing of input shaft structure and spring 7, the number of turns, the bearing of input shaft part of corresponding deflector is used in by suitable coupling spring force, so both can ensure the reasonable friction force of steering gear input shaft, simultaneously also can to axially playing certain supporting role.
In a word; the wearing and tearing of bearing of input shaft are carried out adjustment by the distortion of spring 7 and are absorbed by this programme; make up the endplay of input shaft; increase spring 7 in addition also to turning to the axial impact of input shaft to have certain energy-absorbing function (buffer capacity); namely the impact in vehicle travel process acts on input shaft by the transmission of structure; and spring 7 absorbs the impact energy of a part by deformation energy; so certain protective effect is also played to bearing of input shaft; improve the endurance quality of deflector, add the life-span of deflector.
In order to solve the problems of the technologies described above, the utility model embodiment still provides a kind of steering swivel system, comprising: above-mentioned deflector.
It should be noted that, the described embodiment that realizes of above-mentioned deflector is all applicable in the embodiment of this steering swivel system, also can reach identical technique effect.
