Abstract
The utility model discloses a wheel hub transmission shaft structure, which comprises a flange yoke (1), a universal joint assembly (2), a sliding yoke (3), a spline shaft yoke (5), a universal joint assembly (6) and a spline shaft yoke (7) in sequential arrangement from one end to the other end, wherein a dustproof cover (8) is arranged on the excircle of the sliding yoke (3), and a dustproof device (9) is arranged between the dustproof cover and the excircle of the sliding yoke. In the use process, an outer spline arranged at the tail end of the spline shaft yoke (7) is directly inserted into an inner spline matched with the driving wheel part, and the driving force moment is transmitted through the spline engagement, so the full arrangement of the transmission shaft structure in the limited space can be realized. The wheel hub transmission shaft structure has the advantages that the special requirements of all-wheel driving, ultra-short installation distance, large swinging angle, great length compensation quantity and the like are fully met, the structure is advanced and reasonable, the weight is light, good sealing effects are realized, the service life is long, the whole service life and the operation stability of a transmission shaft assembly are greatly prolonged and improved, and in addition, the serial spectrum of non-constant-speed transmission shafts is expanded.
Description
Technical field
The utility model relates to the truck drive shaft technical field, is specifically related to a kind of non-constant-velocity transmission shaft assembly.
Background technique
In general, non-constant-velocity transmission shaft is used between gearbox and the ransaxle or the transmission of power between transfer case and the driving wheel.Be subjected to installing space position and its to form the restriction of component, non-constant-velocity transmission shaft lengthens easily, shortens difficulty, and is more difficult when being short to a certain degree.
Traditional non-constant-velocity transmission shaft assembly comprises from an end and connects successively flange york, universal-joint cross trunnion assembly (abbreviation universal joint assembly), slip shaft yoke, splined hub, central siphon, universal-joint fork, universal-joint cross trunnion assembly and the flange york of setting to the other end, is provided with dust-proof cover at the splined hub cylindrical.
The vehicle of some specific uses wheel drive of will demanding perfection requires driving-shaft assembly to have the specific functions such as ultrashort mounting distance, big swing angle, big-length compensation rate.Domestic existing non-constant-velocity transmission shaft assembly is subjected to the restriction of the specific condition requirements such as its installing space, all can not satisfy above-mentioned requirements.
The model utility content
The purpose of this utility model is to provide a kind of have ultrashort mounting distance, big swing angle, big-length compensation rate, the suitable non-constant-velocity transmission shaft assembly of all-wheel powered.
For achieving the above object, the limit transmission shaft structure of taking turns of the present utility model comprises flange york, universal-joint cross trunnion assembly, slip yoke, slip shaft yoke, universal-joint cross trunnion assembly and the slip shaft yoke that is connected successively setting by an end to the other end, on the cylindrical of slip yoke, be provided with dust-proof cover, be provided with dust guard between the cylindrical of dust-proof cover and slip yoke.
Be equipped with jump ring between described universal-joint cross trunnion assembly and the slip yoke and between universal-joint cross trunnion assembly and the slip shaft yoke.
The utility model changes an end flange york of assembly parts in the conventional construction transmission shaft into slip shaft yoke, with the specific (special) requirements of the vehicle that reaches specific use.The external splines of this slip shaft yoke end directly is inserted into the internal spline the inside that driving wheel of vehicle partly matches during use, by spline engagement transmission of drive force square, and so just can be at limited the inside, space abundant layout transmission shaft structure.The specific (special) requirements such as the utility model has fully satisfied full wheel drive, has ultrashort mounting distance, big swing angle, big-length compensation rate, structure is rationally advanced, and is lightweight, has good sealing effect, long service life has improved whole service life and the operation stability of driving-shaft assembly greatly.The utility model transmits maximum nominal torque can reach 5500Nm, realizes the shortest mounting distance 420mm, and extreme length compensation rate 120mm realizes 41 ° of maximum pendulum angles, has expanded the serial type spectrum of non-constant-velocity transmission shaft.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the limit transmission shaft structure of taking turns of the present utility model comprises flange york 1, universal-joint cross trunnion assembly 2, slip yoke 3, slip shaft yoke 5, universal-joint cross trunnion assembly 6 and the slip shaft yoke 7 that is connected successively setting by an end to the other end, on the cylindrical 4 of slip yoke 3, be provided with dust-proof cover 8, be provided with dust guard 9 between the cylindrical 4 of dust-proof cover 8 and slip yoke 3.Be equipped with jump ring 11 between described universal-joint cross trunnion assembly 2 and the slip yoke 3 and between universal-joint cross trunnion assembly 6 and the slip shaft yoke 5, jump ring 11 be used for regulating universal-joint cross trunnion assembly 2,6 and slip yoke 3 and slip shaft yoke 5 between the gap.
The external splines of slip shaft yoke 7 ends directly is inserted into the internal spline the inside that driving wheel of vehicle partly matches during use, by spline engagement transmission of drive force square, and so just can be at limited the inside, space abundant layout transmission shaft structure.The specific (special) requirements such as the utility model has fully satisfied full wheel drive, has ultrashort mounting distance, big swing angle, big-length compensation rate, structure is rationally advanced, and is lightweight, has good sealing effect, long service life has improved whole service life and the operation stability of driving-shaft assembly greatly.
