Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
Accompanying drawing, the technical scheme of the embodiment of the present invention is clearly and completely described.Obviously, described embodiment is this hair
Bright part of the embodiment, rather than whole embodiments.Based on described embodiments of the invention, ordinary skill
The every other embodiment that personnel are obtained, belongs to the scope of protection of the invention.
The protection device of vehicle traction semiaxis overload according to embodiments of the present invention is specifically described with reference to accompanying drawing first below
100。
As shown in Figure 1 to Figure 2, the protection device 100 of vehicle traction semiaxis according to embodiments of the present invention overload includes cone
Handle 10, tapered sleeve 20 and end cap 30.
Specifically, taper shank 10 includes first end 11 and the second end 12, and first end 11 is used for and vehicle traction half
Axle is connected includes the 3rd end 21 and the 4th end 22 with output torque, tapered sleeve 20, and the 3rd end 21 is sheathed on the second end 12
Periphery, the 4th end 22 be used for be connected with differential mechanism with input torque, end cap 30 be set in taper shank 10 periphery simultaneously and tapered sleeve
20 the 3rd end 21 is connected.
In other words, the first end 11 of taper shank 10 is connected with vehicle traction semiaxis, the second end 12 and tapered sleeve of taper shank 10
20 the 3rd end 21 is connected, and the 3rd end 21 can be used to be set in the periphery of the second end 12, the 4th end of tapered sleeve 20
22 are connected with the differential mechanism of vehicle, and end cap 30 is set in the periphery of the 3rd end 21 so that taper shank 10 is connected with tapered sleeve 20 more steps up
It is close.When jack shaft moment bearing larger moment of torsion, excessive moment of torsion causes tapered sleeve 20 when passing through tapered sleeve 20 and taper shank 10
3rd end 21 and the junction of the second end 12 of taper shank 10 rotate, so as to be effectively prevented from jack shaft because by larger
Moment of torsion and be broken, effectively protect jack shaft, improve the performance of vehicle.
Thus, the protection device 100 of vehicle traction semiaxis overload according to embodiments of the present invention, by set taper shank 10,
Be set in the tapered sleeve 20 of the one end of taper shank 10 and be set in the periphery of tapered sleeve 20 end cap 30 and three between attachment structure, can
When the jack shaft of vehicle bears excessive torque, make to rotate between tapered sleeve 20 and taper shank 10, so as to be effectively prevented from driving
Semiaxis is broken, and improves the security performance of vehicle, protects the safety of rider.
According to one embodiment of present invention, as shown in figure 1, the diameter of the second end 12 of taper shank 10 is more than first end 11
Diameter, the periphery of the second end 12 formed with the first mating surface 121, the first mating surface 121 along from first end 11 towards
The conical surface that the orient diameter of the second end 12 reduces, the 3rd end 21 are provided with first to be caved inward along the end face of the 3rd end 21
Groove 211, the internal perisporium of the first groove 211 are formed to match with the first mating surface 121.
That is, the diameter of the second end 12 is more than first end 11, and there is the first mating surface the periphery of the second end 12
121, the first mating surface 121 and the wall of the first groove 211 of tapered sleeve 20 match, and when by larger external force effect, first matches somebody with somebody
Friction rotation occurs for the wall of 121 and first groove of conjunction face 211 so that the moment of torsion that jack shaft is subject to does not continue to increase, effectively
Jack shaft overload is avoided to be broken.
According to some embodiments of the present invention, the protection device 100 of vehicle traction semiaxis of the invention overload also includes adjusting
Whole nut 40, adjusting nut 40 are set in the periphery of first end 11 and are connected through end cap 30 with the second end 12, pass through rotation

Frictional force between pitch cone handle 10 and tapered sleeve 20.
That is, adjusting nut 40 is set in the first end 11 of taper shank 10, and one end through end of adjusting nut 40
Lid 30 is simultaneously connected with the second end 12 of taper shank 10, when the cooperation of the first mating surface 121 and the wall of the first groove 211 is prolonged
When causing that frictional force is not enough to transmit moment of torsion or transmit moment of torsion reduction in friction process, by adjusting nut 40 first can be made to match somebody with somebody
Conjunction face 121 is pushed in the first groove 211, so as to keep enough frictional force between the two, to transmit the effect of moment of torsion, recovers to protect
The breakaway torque of device is protected, extends the life-span of protector.
In certain specific embodiments of the invention, as depicted in figs. 1 and 2, vehicle traction semiaxis of the invention overload
Protection device 100 also include butterfly elastomeric element 50, butterfly elastomeric element 50 is located inside end cap 30, and its one end is set in
The periphery of one end 11 and it is connected with adjusting nut 40, the other end is set in the periphery of the second end 12, rotates adjusting nut 40
Taper shank 10 is set to be pressed towards tapered sleeve 20 under the elastic restoring force effect of butterfly elastomeric element 50.
In other words, by setting butterfly elastomeric element 50 between adjusting nut 40 and the second end 12, due to butterfly bullet
Property part 50 itself there is certain elastic force, when the first mating surface 121 and the matching degree of the wall of the first groove 211 reduce, butterfly
Elastomeric element 50 provides the function of compensating automatically, and the second end 12 is pushed in the first groove 211 automatically, to ensure that first coordinates
The frictional force of the wall of 121 and first groove of face 211, while manual de-regulation adjusting nut 40 is not needed, it is time saving and energy saving, pass through setting
Butterfly elastomeric element 50, jack shaft is compensated automatically after wearing and keep breakaway torque to meet design requirement.
According to other embodiments of the present invention, as shown in figure 1, butterfly elastomeric element 50 is provided with the second groove 51, second
The periphery of end 12 is also formed with the second mating surface 122, and the second mating surface 122 is along from first end 11 towards the second end 12
The conical surface of orient diameter increase, the internal perisporium of the second groove 51 match with the second mating surface 122.
That is, being provided with the second groove 51 in butterfly elastomeric element 50, the periphery of the second end 12 is provided with second and coordinated
Face 122, by the cooperation of the second mating surface 122 and the wall of the second groove 51, to increase between the end 21 of the second end 12 and the 3rd
Frictional force, ensure the transmission of moment of torsion.
Preferably, butterfly elastomeric element 50 is spring.
Further, butterfly elastomeric element 50 is plugged on the 3rd end 21 of tapered sleeve 20 by teeth, is connected using teeth
The fastness that increase butterfly elastomeric element 50 is connected with the 3rd end 21 of tapered sleeve 20.
Preferably, tapered sleeve 20 can be used with end cap 30 and is threadedly coupled, and adjusting nut 40 can be that screw thread connects with end cap 30
Connect, using threaded connection, not only facilitated but also quick.
