Abstract
The utility model discloses a connecting structure between a gearbox and a wheel set of a low floor vehicle. The connecting structure between the gearbox and wheel set of the low floor vehicle comprises a gearbox output shaft, an axle and a wheel, wherein the shaft end of the gearbox output shaft is provided with end face teeth; the shaft end of the axle or the end face of the wheel is provided with end face teeth; the end face teeth of the gearbox output shaft are in meshed transmission with those of the axle or those of the wheel. The connecting structure is compact and has a good self-centering effect. The connection is realized from the core part by adopting a large bolt, so that the stress state of the end face teeth is effectively improved, the connecting reliability of the end face teeth is improved, a high torque can be effectively transmitted, and the connecting structure has the advantages of convenience in manufacture, assembly and detachment.
Description
Technical field
The utility model relates to bogie truck Design and manufacture field, be specially a kind of low floor vehicle power truck gear case and wheel pair between connection structure.
Background technology
Its drive system apparatus of traditional power bogie truck, is positioned at wheel mostly to inner side, and its type of attachment is not suitable for the requirement of low floor vehicle power truck, wherein also reliablely reduces the low floor that wheel diameter size realizes vehicle.Some low floor vehicle bogie truck adopts the axle bridge construction of mechanism of independent wheel to form, its drive system apparatus is positioned at the right outside of wheel, driver output axle with wheel pair between often by bolt group, be connected with transmitting torque, its type of attachment has bolt group and connects intrinsic shortcoming, as not high in torsional property.
Utility model content
In order to adapt to the requirement of low floor power truck, the utility model aim to provide a kind of low floor vehicle gear case and wheel pair between connection structure, this connection structure provides a kind of reliable connection of low floor vehicle drive system apparatus on the one hand, can effectively reduce car body height to the top of rail on the other hand, guarantee to realize the low floor of vehicle.
To achieve these goals, the technical scheme that the utility model adopts is:
Low floor vehicle gear case and wheel pair between a connection structure, comprise gearbox output shaft, axletree and wheel; Its constructional feature is, the axle head of described gearbox output shaft has end-tooth, and the axle head of described axletree or the end face of wheel have end-tooth, the chimeric transmission of end-tooth of the end-tooth of described gearbox output shaft and the end-tooth of described axletree or wheel.
In order to improve the reliability of the chimeric transmission of end-tooth, described gearbox output shaft and described axletree or wheel are fixedly linked.Preferably, described gearbox output shaft is the hollow shaft with centre hole, and the center, end of described axletree or wheel offers tapped bore, and this hollow shaft is fixedly linked through the pretension king bolt of centre hole and described axletree or wheel by one.
By said structure, the utility model is placed on the right end of wheel by the wheel of low floor vehicle to power transmission interface, gearbox output shaft and axletree or wheel end are designed to suitable end-tooth and chimeric, and adopt king bolt structure pretension, realize power from gear case to the right transmission of wheel.A kind of reliable connection of low floor vehicle drive system apparatus is provided on the one hand, can have effectively reduced car body height to the top of rail on the other hand, guaranteed to realize the low floor of vehicle.
Compared with prior art, the beneficial effects of the utility model are: the utility model reasonably designs wheel offside and gearbox output shaft side end face tooth, and its compact conformation has good acting on from centering.Adopt king bolt to connect and effectively improve end-tooth strained condition from core, improved the reliability that end-tooth connects, can effectively transmit larger moment of torsion, there is manufacture, assembly and disassembly advantage easily.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
Accompanying drawing explanation
Fig. 1 is the structure principle chart that the utility model gear case is connected with wheel;
Fig. 2 is the part sectional view that in Fig. 1, end-tooth is connected and fixed;
Fig. 3 is the structure principle chart that the utility model gear case is connected with axletree;
Fig. 4 is the part sectional view that in Fig. 3, end-tooth is connected and fixed.
In the drawings

6-axletree; 7-pretension king bolt; 8-hollow shaft; 9-gearbox output shaft.
the specific embodiment
Low floor vehicle gear case and wheel pair between a connection structure, as Figure 1-Figure 4, comprise gearbox output shaft 9, axletree 6 and wheel 3; The axle head of described gearbox output shaft 9 has end-tooth 4, and the end of described axletree 6 or wheel 3 has end-tooth 4, and the end-tooth 4 of described gearbox output shaft 9 is with described axletree 6 or take turns the chimeric transmission of end-tooth 40 to 3.
Thus, by end face tooth structure size and dentation form are reasonably designed, end-tooth is processed respectively on axletree 6 or wheel 3 ends and gearbox output shaft 9, adopts chimeric installation and king bolt structure pretension.Described gearbox output shaft 9 is for having the hollow shaft 8 of centre hole, adopt king bolt to be fixedly connected with pretension through hollow shaft 8 with axletree 6 or wheel 3, this pre-pressing structure have compact conformation, good when centering effect can improve chimeric transmission effectively end- tooth 4,40 strained condition, improve the reliability that end-tooth connects, can effectively transmit larger moment of torsion.
The content that above-described embodiment is illustrated should be understood to these embodiment only for being illustrated more clearly in the utility model, and be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
