Compared with prior art, the utility model has the advantages that: bearing carrier ring is delivered to conical roller thrust bearing by suffered load by the step of bearing carrier ring, entered again sleeve, bearing inner ring is delivered to load receiving part step, and then be delivered to wheel carrier, wheel, area of thrust surface are increased, change the some contact of double-deck bearing hoodle of the prior art into line contact in conical roller thrust bearing, improve the weight capacity of cardan wheel, in addition conical roller thrust bearing outer ring is separable, so bearing carrier ring, vehicle frame can separate with pivot, the utility model cardan wheel is easy to remove and repair, change.
Further, described bearing carrier ring is provided with the oil nozzle of carrying lubricating oil, and lubricating bearings reduces friction.
Further, pivot and vehicle frame junction are provided with dust ring, prevent that dust from entering bearing carrier ring and damaging bearing.
The utility model also provides a kind of go-cart, with solve in prior art the specified load-bearing of go-cart low, transport inconvenient problem
For solving the problems of the technologies described above, go-cart in this programme, comprise vehicle frame and cardan wheel, vehicle frame comprises horizontally disposed annular supporting frame, be located at the guardrail of supporting frame both sides and with the fixing road wheel of supporting frame, described supporting frame is provided with multiple parallel middle parts bending cross bar earthward, described supporting frame, cross bar and guardrail are hollow tubular and make, and described cardan wheel and supporting frame removably connect.
Compared with prior art, the utility model has the advantages that: this programme has adopted the cardan wheel of the high bearing capacity described in such scheme, cardan wheel load-bearing is high, supporting frame, cross bar and guardrail are hollow tubular and make, so vehicle frame is light, in addition vehicle frame is provided with guardrail, cross bar middle part is bending earthward, and this has just been avoided goods to skid off from shelf, convenient transportation.
Further, described supporting frame is provided with connecting panel, between cardan wheel and connecting panel, is connected by nut, is easy to remove and repair and even changes.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model cardan wheel embodiment;
Fig. 2 is the structural representation of the utility model go-cart embodiment.
The specific embodiment
Embodiment mono-as shown in Figure 1, cardan wheel in the utility model embodiment, comprise wheel 4, wheel carrier 3 and be vertically fixed on the pivot that the length on wheel carrier 3 is 106mm, wheel 4 is articulated in wheel carrier 3, wheel carrier 3 is provided with the pivot of connecting vehicle frame, also comprise that one end is fixed on the bearing carrier ring that is provided with step 1 on vehicle frame, pivot comprises load receiving part 22, connecting portion 21 and sleeve 23 with load receiving part 22 one, load receiving part 22 diameters are 30mm, length is 62mm, connecting portion 21 is threaded with vehicle frame, on load receiving part 22, be connected with conical roller thrust bearing 221 and deep groove ball bearing 222, load receiving part 22 is one-body molded with connecting portion 21, load receiving part 22 is provided with load-bearing step 223 away from connecting portion 21 one end, conical roller thrust bearing 221 is near connecting portion 21, deep groove ball bearing 222 contacts with load-bearing step 223, sleeve 23 connects the inner ring of conical roller thrust bearing 221 and the inner ring of deep groove ball bearing 222, bearing carrier ring 1 is socketed on the outer ring of deep groove ball bearing 222, conical roller thrust bearing 221, on bearing carrier ring 1, be provided with and the annular table of bearing carrier ring 1 one near one end of conical roller thrust bearing 221, annular table is pressed in conical roller thrust bearing 221 outer rings, and conical roller thrust bearing 221 outer rings are against on the step of bearing carrier ring 1.
