Embodiment
Below by way of specific instantiation, mode of execution of the present utility model is described, those skilled in the art the content disclosed by this specification can understand other advantages of the present utility model and effect easily.The utility model can also be implemented or be applied by embodiments different in addition, and the every details in this specification also can based on different viewpoints and application, carries out various modification or change not deviating under spirit of the present utility model.
Middle multifunctional vehicle speed changer shown in 1 display with reference to the accompanying drawings, comprise casing 1, casing 1 is provided with gear input shaft 2, input end is by inputting land 3 by transmission of power to input shaft 2, input shaft 2 arrives inner through casing 1, coordinated by two groups of deep groove ball bearings 4 and oil sealing 5 with casing 1, gear input shaft 2 and output shaft 6 are coaxially arranged, and output shaft 6 is arranged dorsad with the input end of gear input shaft 2.Output shaft 6 is fixed on casing 1 by bearing, and output shaft 6 is provided with tooth hub 7, tooth cover 8, and tooth cover 8 is driven by shift fork 9 and moves left and right.Tooth overlaps 8 both sides and can engage with a driven gear 11 on the gear 10 of gear input shaft 2 and output shaft 6 respectively.A driven gear 11 empty set, on output shaft 6, to be unpoweredly connected with it, can independently to rotate each other.Output shaft 6 the other end is coordinated by two groups of deep groove ball bearings 12 and oil sealing 13 with casing 1 outside extending to through casing 1, and the output terminal of output shaft 6 is provided with and exports land 14, is connected with miscellaneous part by exporting land 14.
When shift fork 9 is toward moving left, the gear 10 of tooth cover 8 and gear input shaft 2 engages, power imports into from the input land 3 of input shaft 2, then driven input shaft 2 is with to rotate, the tooth cover 8 gear 10 of gear input shaft 2 being driven be engaged with rotates, and tooth cover 8 is by transmission of power to tooth hub 7, and drive output shaft 6 rotates, power is directly delivered to and exports land 14, outside being passed to by output shaft 6.Now, output shaft and input shaft realize the transmission of power ratio of 1:1.
