Below with reference to accompanying drawing, describe the retarder assembly according to the embodiment of the present invention in detail.
As shown in Figures 1 to 6, the retarder assembly according to the embodiment of the present invention, comprising: retarder body 10, drive plate 20 and torsion vibration absorber 30.
Specifically, retarder body 10 has reducer input shaft 102.
Drive plate 20 has drive plate axle 201.Drive plate axle 201 is connected with reducer input shaft 102.
Torsion vibration absorber 30 be connected with drive plate 20 and torsion vibration absorber 30 on there is damping internal spline hub 301.
At this, it should be noted that, retarder body 10 can be a double reduction gear with differential mechanism 106.As shown in Figure 3, power is inputted by reducer input shaft 102, after primary speed-down 103, jack shaft 104 and double reduction 105 slow down, by differential mechanism 106, is exported successively.In addition, torsion vibration absorber 30 can be conventional all cloth spring torsion vibration absorber.As shown in Figure 6, the damping Nei Hua Jian Grains 301 in the middle of torsion vibration absorber 30 can match with the external splines on the output shaft of drive motor 60.Torsion vibration absorber 30 is connected with drive plate 20, during work, the output shaft of drive motor 60 drives damping Nei Hua Jian Grains 301, damping Nei Hua Jian Grains 301 is delivered to holding sheet 305 by damping spring 304 by power, on 306, holding sheet 306 is fixed on drive plate 20, thereby by drive plate 20, power is passed on deceleration input shaft 102 again.In transmittance process, the impact-attenuating that all cloth damping springs 304 by torsion vibration absorber 30 cause rotating speed, change in torque falls.This is understandable for the person of ordinary skill of the art.
According to the retarder assembly of the embodiment of the present invention, set up torsion vibration absorber, can attenuate shock power to obtain good damping effect.
According to an example of the present invention, as shown in Figure 4, drive plate axle 201 is male splined shaft.As shown in Figure 3, reducer input shaft 102 is formed with the internal spline hub (not shown) suitable with described male splined shaft so that described male splined shaft is plugged in described internal spline hub.Advantageously, on described male splined shaft, there is the first interior threaded hole 2011 that connects described male splined shaft.On reducer input shaft 102, have be communicated with described internal spline hub and with suitable the second interior threaded hole 1021 of the first interior threaded hole 2011, drive plate 20 is fixed on reducer input shaft 102, as shown in Figures 2 and 3 by the first clamping bolt 1020.Thus, can be being connected firmly of drive plate 20 and retarder body 10.
According to an example of the present invention, as shown in Figure 5, on drive plate 20, there is locating stud 202.As shown in Figure 6, on torsion vibration absorber 30, there is the positioning pin hole 302 suitable with locating stud 202.Advantageously, locating stud 202 is for a plurality of and be evenly arranged along the circumferential interval of drive plate 20, and positioning pin hole 302 is a plurality of one to one with a plurality of locating studs 202.Thus, can make torsion vibration absorber 30 be arranged on easily on drive plate 20.
According to an example of the present invention, as shown in Figure 5, on drive plate 20, also there is the bolt hole 203 of positioned adjacent pin 202.As shown in Figure 6, on torsion vibration absorber 30, there is the fixed hole 303 suitable with bolt hole 203, torsion vibration absorber 30 is fixed on drive plate 30 by the second clamping bolt 2030.Thus, can make torsion vibration absorber 30 more firm with being connected of drive plate 20.
If Fig. 1 is to as shown in 3, according to an example of the present invention, according to the bumper assembly of the embodiment of the present invention, also comprise transitional crust 40, transitional crust 40 is connected with retarder body 10.Advantageously, on transitional crust 40, be formed with the receiving cavity 401 that holds drive plate 20 and torsion vibration absorber 30.Thus, can protect drive plate 20 and torsion vibration absorber 30.
At this, it should be noted that, transitional crust 40 is the transition pieces between retarder body 10 and drive motor 60, plays the effect of protection drive plate 20, torsion vibration absorber 30 simultaneously.The end face that transitional crust 40 is connected with drive motor 60 can design according to the housing end face of motor, to guarantee the generalization of retarder body.For example, transitional crust 40 can connect together by bolt with the output shaft end face of drive motor, also can make as required by connecting plate 50, to connect between the two.
Simply introduce below according to the installation process of the retarder assembly of the embodiment of the present invention.
As shown in Figure 2, first, by connecting bolt 1040, transitional crust 40 is fixed on retarder body 10; Then, drive plate 20 is plugged on reducer input shaft 102 and with the first clamping bolt 1020 drive plate 20 is fixed; Finally, the positioning pin hole of torsion vibration absorber 30 302 is matched with the locating stud 202 of drive plate 20, and by the second clamping bolt 2030, torsion vibration absorber 30 is fixed on drive plate.
As shown in Figure 7, when being connected with drive motor 60 according to the bumper assembly of the embodiment of the present invention, drive motor 60 output shaft external spliness match with the damping internal spline hub 301 of torsion vibration absorber on retarder.When drive motor 60 drives vehicle, the moment of torsion of motor shaft output is delivered on reducer input shaft 102 by torsional vibration damper 30, drive plate 20, then is turned round from differential mechanism 106 and exported to the semiaxis of car load left and right by the deceleration increasing of retarder body 10.When the rotating speed of drive motor 60 or moment of torsion change; torsional vibration damper 30 on retarder can decay to minimum by changing thus the impact force causing; thereby can guarantee in vehicle operating process steady; improve car load travelling comfort; also protected the transmission system that comprises retarder body 10, improved its working life simultaneously.
