Description
Technical field
The utility model belongs to technical field of automobile parts, is specifically related to steering column regulating mechanism.
Background technology
In order to improve driving comfort, adapt to the driving demand of different stature chaufeurs, modern automobile is all furnished with adjustable steering column, chaufeur unclamps after the regulating handle of tunable arrangement, according to bearing circle need to being regulated in place of self, and then operation regulating handle is to the position of locking.As shown in Figure 1, the principle of conventional adjustment mechanisms is as follows: the first cam bit and regulating handle are assembled together, the second cam bit coordinates with the bar shaped groove that regulates stent side portion, in the time that operation regulating handle turns to locked position, the convex surface of the first cam bit and the second cam bit coordinates, thereby make to regulate gap between support and medium-height trestle to be eliminated, both can not relative motion, the now position of bearing circle in locking; In the time that operation regulating handle turns to release position, the concave surface of the first cam bit and the second cam bit coordinates, regulate the gap between support and medium-height trestle to be released, both can relative motion, now when direction of operating dish, medium-height trestle drives adjusting screw(rod) and the second cam bit to move along the bar shaped groove that regulates support, and bearing circle can be adjusted to the optional position between high-low limit.Stamping forming owing to regulating support, when the punching of bar shaped groove, be difficult to guarantee to regulate bar shaped groove surface quality, tear-strap when punching often accounts for significant proportion, easily forms laciniation, in the time regulating bearing circle, when the second cam bit and adjusting screw(rod) move along bar shaped groove, because bar shaped groove air spots is sliding, produce regulating mechanism friction abnormal sound, the phenomenon such as astringent, causes bad sensation to chaufeur.
Summary of the invention
The purpose of this utility model is to propose a kind of steering column regulating mechanism, produces phenomenon such as friction abnormal sound etc. when avoiding bearing circle to regulate, regulates texture thereby improve, and provides comfortable adjusting function to chaufeur.
Steering column regulating mechanism of the present utility model comprises adjusting support, medium-height trestle, steering-column tube, the first cam bit, the second cam bit, regulating handle, adapter shaft, described medium-height trestle is fixedly connected with steering-column tube, described regulating handle is fixedly connected with the first cam bit, described medium-height trestle is provided with through hole, regulate support to be provided with bar shaped groove, described adapter shaft is through the through hole of medium-height trestle, regulate bar shaped groove and first cam bit of support, the second cam bit, thereby by medium-height trestle, the first cam bit, the second cam bit is flexibly connected with regulating support, described the second cam bit is located in the first cam bit and regulates between support, key is described the second cam bit and regulates between support ganoid slide guide sheet is also installed, and described slide guide sheet is fixedly connected with regulating support, and slide guide sheet is provided with the pilot hole corresponding with bar shaped groove position, shape conforms to.
In the time regulating the position of bearing circle, the second cam bit can rub with slide guide sheet, but because slide guide sheet is more smooth with respect to regulating the bar shaped groove of support, therefore when the second cam bit slides, can not produce the phenomenons such as friction abnormal sound, thereby improve adjusting texture, provide comfortable adjusting function to chaufeur.
Further, the edge of the pilot hole of described slide guide sheet is provided with towards the flange that regulates holder orientation, described flange and the bar shaped groove interference fit that regulates support, thus slide guide sheet is fixedly connected with regulating support.Above-mentioned flange has not only been realized the effect fixing with regulating support of slide guide sheet, but also can isolate contacting of adapter shaft and bar shaped groove cell wall, adapter shaft only can be contacted with flange in the control process of bearing circle, because flange is more more smooth than bar shaped groove cell wall, therefore reduce friction abnormal sound.
Further, described slide guide sheet is arc, slide guide sheet can produce certain elastic deformation after assembling like this, makes the first cam bit, the second cam bit, regulates the gap between support, medium-height trestle to reduce, and stops above-mentioned all parts because rocking the noise producing.
Further, for convenience of location and installation, described slide guide sheet is provided with the concavo-convex location structure coordinating with the contact surface that regulates support.
The utility model is on the basis of traditional steering column regulating mechanism, increase smooth slide guide sheet in the bar shaped groove position that regulates support both sides, reduce friction abnormal sound phenomenon when the second cam bit, adapter shaft bar shaped groove move, thereby improve adjusting texture, provide comfortable adjusting function to chaufeur.

The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail as effect and the principle of work etc. of the mutual alignment between the shape of related each member, structure, each several part and annexation, each several part.
Embodiment 1:
As shown in the figure, the steering column regulating mechanism of the present embodiment comprises adjusting support 1, medium-height trestle 2, steering-column tube 3, the first cam bit 4, the second cam bit 5, regulating handle 6, adapter shaft 7, described medium-height trestle 2 is fixedly connected with steering-column tube 3, described regulating handle 6 is fixedly connected with the first cam bit 4, described medium-height trestle 2 is provided with through hole, regulate support 1 to be provided with bar shaped groove 11, described adapter shaft 7 is through the through hole of medium-height trestle 2, regulate bar shaped groove 11 and first cam bit 4 of support 1, the second cam bit 5, and screw with a nut 8, thereby by medium-height trestle 2, the first cam bit 4, the second cam bit 5 is flexibly connected with regulating support 1, described the second cam bit 5 is located in the first cam bit 4 and regulates between support 1, key is, between described the second cam bit 5 and adjusting support 1, the slide guide sheet 9 that adopts 65Mn to make is also installed, described slide guide sheet 9 smooth surfaces, and slide guide sheet 9 is provided with the pilot hole 91 corresponding with bar shaped groove 11 positions, shape conforms to, the edge of pilot hole 91 is provided with towards the flange 92 that regulates support 1 direction, described flange 92 and bar shaped groove 11 interference fit that regulate support 1, thus slide guide sheet 9 is fixedly connected with regulating support 1.
In the time regulating the position of bearing circle, the second cam bit 5 can rub with slide guide sheet 9, adapter shaft 7 can rub with the flange 92 of slide guide sheet 9, but because slide guide sheet 9 is more smooth with respect to regulating the bar shaped groove 11 of support 1, therefore when the second cam bit 5 and adapter shaft 7 slide, can not produce the phenomenons such as friction abnormal sound, thereby improve adjusting texture, provide comfortable adjusting function to chaufeur.
