Vehicle transmission gear

Abstract

The invention provides a vehicle transmission device, comprising a transmission unit and a transmission unit which is driven to run by the transmission unit; the vehicle transmission device is arranged on the main box body of the transmission unit by the auxiliary box body of the transmission unit in a dismountable way; furthermore, a second transmission structure of the transmission unit and a transmission output shaft are arranged in the auxiliary box body; therefore, the transmission unit can be taken as a modularized design and can be elastically replaced according to different requirements; furthermore, when the vehicle transmission device changes the wheel distance or speed reducing ratio, only the transmission unit with small volume and simple component is needed replacing, withoutreplacing the main box body with huge volume or changing the specification, thus avoiding spending more cost and time to re-mold for manufacturing the main box body of a new specification, thereby effectively reducing the manufacture cost and time.

Description

technical field [0001] The invention relates to a vehicle transmission device, in particular to a vehicle transmission device which uses the power output by the engine to run and drive the vehicle forward. Background technique [0002] Referring to Fig. 1, the existing vehicle transmission device 1 comprises a hollow casing 11, a transmission unit 12 installed in the casing 11, and a transmission unit 12 which is also installed in the casing 11 and is held by the transmission unit 12. The transmission unit 13 is driven to run, wherein the box body 11 is assembled by a shell portion 111 and a cover portion 112 . [0003] The transmission unit 12 utilizes the combination of two pulleys 121 (only one of which is shown in FIG. 1 ) and a V-belt 122 to be driven by the power output by the engine (not shown), and then a transmission output shaft 123 is worn through One of the pulleys 121 is provided, so that the power output by the engine will be transmitted to the transmission ou...

Problems solved by technology

[0009] However, the selectable setting positions of the speed change output shaft 25 are limited to only two kinds (i.e. the two positions of the rightmost bearing part 28 and the middle bearing part 27), which are not easy to meet the changing needs of the market; It is necessary to adjust the variable speed output shaft 25 to another position. At this time, a new specification of the box body 20 must be made, which relatively increases the cost of mold opening and manufacturing. As for the box body 20 of the old specification, it must be replaced and stored separately. Occupies a considerable storage space, therefore, the vehicle transmission 2 still has the disadvantages of lack of flexibility in assembly and insufficient flexibility in use

[0010] In view of the above-mentioned two existing vehicle transmission devices 1 and 2, they are prone to disadvantages such as difficulty in meeting market demand, high manufacturing cost, and lack of flexible selection in use. Therefore, how to improve and solve them has become the desire of the relevant industry. direction of research
