Abstract
The utility model discloses an energy absorption device for an intermediate shaft of an automobile steering column. The energy absorption device comprises a circular pipe a (11) and a circuit pipe b (12) which are coaxially arranged, wherein the inner diameter of the circular pipe a is larger than the outer diameter of the circular pipe b, a plurality of spokes (13) which are integrated with the circular pipe a and the circular pipe b are uniformly arranged between the circular pipe a and the circular pipe b, and the spokes axially extend between the circular pipe a and the circular pipe b; the circular pipe a, the circular pipe b and the spokes are all made of rubber; a coaxial circular pipe-shaped steel sleeve (14) is embedded into the pipe wall of the circular pipe a, and the energy absorption device is fixed on the intermediate shaft (2) of the automobile steering column by the circular pipe b. After being installed on the intermediate shaft, due to that the natural frequency of the energy absorption device is the same as that of the intermediate shaft, the energy absorption device for the intermediate shaft of the automobile steering column can absorb swinging and vibrating energy of the steering column when the steering column swings and vibrates, so as to lessen or eliminate the swinging and vibrating, thereby improving the driving comfort degree.
Description
Technical field
The utility model relates to the steering column for vehicles field, especially relates to a kind of steering column for vehicles tween drive shaft energy absorption device.
Background technology
Automobile is in running at high speed, and the front vehicle wheel both sides are subjected to ground-surface excitation, and can swinging, it is shimmy to form.The shimmy Steering gear that is passed to of wheel, Steering gear can resonate when shimmy frequency is identical with the Steering gear natural frequency, and then it is shimmy to drive the bearing circle generation, has influence on the traveling comfort of driving in the car.The shimmy of front vehicle wheel can hardly be avoided, and can reduce the shimmy of bearing circle so reduce the shimmy of Steering gear, and then improves the traveling comfort of driving.The vibration of having been transmitted when only having considered to reduce the front-wheel movement up and down or around on the nowadays various Steering gears, this class shock absorber can't be eliminated shimmy on the Steering gear, make still to have the shimmy influence that causes on the bearing circle.The Chinese utility model patent specification sheets of the CN201283888Y that on August 5th, 2009 was announced discloses a kind of later-model motor turning driving device, in this device, is connected by adapter shaft, bellows, castellated shaft, spline housing and nonrigid connector respectively in the middle of the two ends joint yoke assemblies, eliminates the transfer of vibration of lower end from direction machine etc.This device can weaken because the vibration that is produced during the front-wheel movement up and down or around, but can't eliminate the shimmy of Steering gear, makes still to have bad vibration on the bearing circle, influence the interior driver comfort of car.
The utility model content
The utility model mainly is to solve the shock attenuation unit that exists in the prior art can't eliminate shimmy on the Steering gear, influence the problem of the driver comfort in the car, a kind of steering column for vehicles tween drive shaft energy absorption device is provided, this device can weaken or eliminate shimmy on the Steering gear, and then weaken or eliminate Steering gear and be passed to shimmy on the bearing circle, improve the traveling comfort of driving in the car.
In order to solve the problems of the technologies described above, the utility model has adopted a kind of like this steering column for vehicles tween drive shaft energy absorption device, it is characterized in that, this device comprises the pipe a and the pipe b of coaxial setting, the internal diameter of pipe a is greater than the external diameter of pipe b, spoke some and pipe a and pipe b one evenly is set between described pipe a and pipe b, described spoke extends between pipe a and pipe b vertically, described pipe a, the material of pipe b and spoke is a rubber, tube wall at described pipe a is embedded in coaxial tubular steel bushing, and this device is fixed on the steering column for vehicles tween drive shaft by described pipe b.Adjust the quality of pipe a, spoke and steel bushing according to the natural frequency of Steering gear, the natural frequency that makes this device is identical with Steering gear, this device is installed on the Steering gear tween drive shaft, when Steering gear takes place when shimmy, because this device is identical with the natural frequency of Steering gear, so this device resonates, this device can the shimmy energy of absorbable steering column like this, and then weaken or eliminate shimmyly, improved the traveling comfort of driving.
As preferably, the shore hardness of described rubber is 35.Use the rubber of this specification can the required rigidity of assurance device.
As preferably, the material of described steel bushing is the Q235A steel.Use the steel of this specification can the required rigidity of assurance device.
As preferably, the quantity of described spoke is 6.The rigidity that how much influences device of spoke quantity, spoke are set to 6, can both guarantee manufacturing cost, again the required rigidity of assurance device.
After steering column for vehicles tween drive shaft energy absorption device of the present utility model is installed on the tween drive shaft, because this device is identical with the natural frequency of tween drive shaft, take place when shimmy when Steering gear like this, this device can the shimmy energy of absorbable steering column, and then weaken or eliminate shimmyly, improved the traveling comfort of driving.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an axial cutaway view of the present utility model;
Fig. 3 is that the utility model is installed in the structural representation on the Steering gear tween drive shaft.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, steering column for vehicles tween drive shaft energy absorption device 1 of the present utility model comprises pipe a11 and pipe b12, pipe a11 and pipe b12 are coaxial, the internal diameter of pipe a11 is greater than the external diameter of pipe b12,6 spokes 13 with pipe a11 and pipe b12 one evenly are set between described pipe a11 and pipe b12, spoke 13 extends between pipe a11 and pipe b12 vertically, and pipe a11, pipe b12 and spoke 13 all adopt rubber as material, and the shore hardness of this rubber is 35.As shown in Figure 2, be provided with cavity in the tube wall of pipe a11, be embedded in pipe shape steel bushing 14 at this cavity, this steel bushing 14 is coaxial with pipe a11, and this steel bushing 14 uses Q235A steel, the internal diameter of pipe b12 and steering column for vehicles tween drive shaft 2 interference fit.
Like this can be according to the natural frequency of Steering gear, by adjusting the quality of pipe a11, spoke 13 and steel bushing 14, the natural frequency that makes this device 1 is identical with Steering gear.As shown in Figure 3, this device 1 is installed on the Steering gear tween drive shaft 2, when Steering gear takes place when shimmy, this device 1 can the shimmy energy of absorbable steering column, and then weakens or eliminate shimmyly, has improved the traveling comfort of driving.
