Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
A kind of angle of steering tubular column governor motion as shown in Figure 1, including steering column 1, regulates support 2 and adjusting rod 5;Being fixedly connected with support on steering column 1, support is provided with through hole;As in figure 2 it is shown, regulate support 2 to be provided with two blocks of side plates 3, two blocks of side plates 3 being equipped with the first bar hole 4, support, between two blocks of side plates 3, regulates support 2 for being connected with vehicle body;Adjusting rod 5 traverse through hole and two the first bar holes 4, to connect support and to regulate support 2, adjusting rod 5 is provided with locking mechanism, and adjusting rod 5 can be locked on adjustment support 2 by locking mechanism, and adjustment locking mechanism can release adjusting rod 5 and the locking state regulated between support 2;First bar hole 4 is provided with resilient bushing 10, resilient bushing 10 and the first bar hole 4 interference fit, resilient bushing 10 has the second bar hole 14, the length direction of the second bar hole 14 and the length direction of the first bar hole 4 are consistent, second bar hole 14 one end in its longitudinal direction is big width end 15, the other end is little width end 16, and the width of the second bar hole 14 is gradually reduced to little width end 16 by big width end 15;Adjusting rod 5 can slide into little width end 16 from big width end 15 through two the second bar holes 14 and adjusting rod 5, the sidewall of adjusting rod 5 and the second bar hole 14 offsets and forms the sidewall elastic deformation along the width of the second bar hole 14 of the second bar hole 14, the diameter of adjusting rod 5 is more than the width of the little width end 16 of the second bar hole 14, and the width of the big width end 15 of the second bar hole 14 is more than the diameter of adjusting rod 5.The present invention is assemblied on automobile and when automobile is placed on level ground, and the distance between little width end 16 and level ground is less than the distance between big width end 15 and level ground.
Preferred as one, as shown in Figure 3, resilient bushing 10 is the circulus defined by two short elastic strips 17 and two long elastic strips 18, has at least the long elastic strip 18 thickness on resilient bushing 10 width to be gradually increased to little width end 16 by big width end 15.Resilient bushing 10 is formed in one part.
Preferred as one, the first bar hole 4 and the second bar hole 14 are arc slot.
Concrete, locking mechanism includes clamping block 6, fixing cam 8, operation of cam 9 as shown in Figure 4, regulates handle 7 and nut 11;Clamping block 6 is fixed on one end of adjusting rod 5, and nut 11 is assemblied in the other end of adjusting rod 5, and fixing cam 8 and operation of cam 9 are all enclosed within adjusting rod 5 and are respectively positioned on nut 11 and regulate between support 2;As shown in Figure 5, fixing cam 8 is provided with, towards the side regulating support 2, the CAM profiles 13 coordinated with the second bar hole 14, the side that fixing cam 8 regulates support 2 dorsad is formed with the first cam projection, operation of cam 9 is formed with, towards the side regulating support 2, the second cam projection being connected in the first cam projection, regulate handle 7 and be connected in operation of cam 9, nut 11 is for limiting operation of cam 9 and regulating the position of handle 7, packing ring 12 it is provided with between nut 11 and operation of cam 9, packing ring 12 is conflicted and is being regulated on handle 7, and packing ring 12 can replace with bearing.
The fixing cam 8 that operation of cam 9 is configured to relative to being connected on adjustment support 2 rotates against.That is, when driver rotates adjustment handle 7 in one direction to lock, operation of cam 9 rotates relative to fixing cam 8 and the first cam projection and the second cam projection match so that fixing cam 8 has towards the clamping force regulating support 2, so that adjustment support 2 is clamped by fixing cam 8 with clamping block 6, thus lock adjustment support 2 and adjusting rod 5.Simultaneously as fixing cam 8 is formed with the CAM profiles 13 inserted in the resilient bushing 10 regulated on support 2, when driver rotates adjustment handle 7, even if operation of cam 9 rotates, fixing cam 8 does not also rotate.When driver is when reversely rotating adjustment handle 7 to carry out releasing locking state, operation of cam 9 rotates against relative to fixing cam 8 and the first cam projection and the second cam projection progressively disengage, to release on fixing cam 8 towards the clamping force regulating support 2 so that adjusting rod 5 can slide along the second bar hole 14.
The present invention is operationally, the locking state regulated between support 2 and adjusting rod 5 is released by rotating adjustment handle 7, then just available adjusting rod 5 regulates the angle of steering column 1 along the slip of the second bar hole 14, adjustment reversely rotates adjustment handle 7 after completing just can lock adjustment support 2 and adjusting rod 5, it is achieved fixing of steering column 1 position.When the locking state regulated between support 2 and adjusting rod 5 releases, steering column 1 has the trend of a tenesmus under the effect of deadweight, but the width of the second bar hole 14 on Elastic lining 10 of the present invention is gradually reduced, when steering column 1 drops, gap between resilient bushing 10 and adjusting rod 5 tapers into, it is gradually transitions interference fit by matched in clearance between resilient bushing 10 and adjusting rod 5, the counteracting force produced by resilient bushing 10 compression plays cushioning effect, delay the tenesmus process of steering column 1, play cushioning effect when steering column 1 regulates, avoid unexpected tenesmus when steering column 1 regulates, improve the operating handle of driver.Simultaneously resilient bushing 10 is arranged between adjusting rod 5 and the first bar hole 4, it is to avoid adjusting rod 5 and the collision regulated between support 2 and friction, serves noise reduction, alleviates the effect of vibration, it is thus also avoided that adjusting rod 5 and regulate the abrasion of support 2.
Owing to the CAM profiles 13 on fixing cam 8 is arranged to coordinate with the second bar hole 14, preferred as one, the CAM profiles 13 thickness on the second bar hole 14 width is more than the width of the little width end 16 of the second bar hole 14, and the width of the big width end 15 less than the second bar hole 14.When regulating the angle of steering column 1, CAM profiles 13 slides in the second bar hole 14, cushioning effect can be played by the counteracting force that resilient bushing 10 compression produces, delay the tenesmus process of steering column 1 further, playing cushioning effect when steering column 1 regulates, the CAM profiles 13 of this structure enhances buffering effect.In like manner, clamping block 6 can also arrange the projection coordinated with the second bar hole 14, to promote the technique effect of the present invention.
