Abstract
The utility model discloses a turning vehicle-mounted transmission case, which comprises a transmission case body, an operating handle, a shifting fork, a spline shaft and a slideable driving gear sheathed on the spline shaft and further comprises a pair of transmission bevel gears and a regulating device used for regulating the axial position of the spline shaft; and the transmission bevel gears are connected between the spline shaft and an output shaft, and the regulating device is fixed at the two ends of the spline shaft. The bevel gears are transmitted to lead the power transmission direction to be changed in 90-degree so that operating requirements for vehicles are satisfied; meanwhile, the regulating device further can regulate the axial position of the spline shaft at any time so as to eliminate a backlash possibly generated between the bevel gears in a long-term engagement process and avoid generating axial motion. The overall structure has high transmission precision and stable and reliable transmission quality, and the turning vehicle-mounted transmission case is suitable for all vehicles in matching use.
Description
Technical field
The utility model relates to a kind of vehicle-mounted transmission case that is used for the break-in transmission, belongs to auto parts and components and makes the field.
Background technique
The vehicle transmission case is mainly used in the direction that changes engine output power, makes the power outbound course meet the vehicle traction requirement, finishes power and exports smoothly.Existing transmission case is not enough owing to existing in structure and the design, and axial float appears in transmission process easily, the transmission process instability, and serious wear is brought potential safety hazard to vehicle driving.
Summary of the invention
In view of above-mentioned deficiency of the prior art, the purpose of this utility model provides a kind of reliable transmission, turns round steadily, adjusts the vehicle-mounted transmission case of break-in flexibly.
The utility model is achieved through the following technical solutions:
The vehicle-mounted transmission case of break-in, comprise transmission case casing, operating grip, shift fork, splined shaft and be enclosed within on the splined shaft slidably driving gear, driving gear receives the rotating power of extraneous input, also comprise a pair of drive bevel gear, and the controlling device that is used to adjust the splined shaft axial position, drive bevel gear is connected between splined shaft and the output shaft, and controlling device is fixed on the splined shaft two ends.
Described controlling device comprises end cap, cover plate, adjusting bolt and oil sealing, end cap is fixed on the transmission case casing, and cover plate is supported on the outside of splined shaft bearing, regulates bolt and is connected on the end cap, the top of regulating bolt withstands on the cover plate, and oil sealing is between end cap and transmission case casing.
The vehicle-mounted transmission case of break-in described in the utility model, by increasing bevel-gear sett, the power feeding direction is changed, satisfy the use needs of vehicle traction, guaranteed the continuity and the validity of transmission of power, simultaneously, increase axial controlling device at the splined shaft two ends, the splined shaft position can axially be adjusted as required at any time, eliminate in the long-term engagement process issuable back lash between bevel gear, avoid the situation of transmission stability difference and axial float to take place.At any time the adjustment of axial position has improved the transmission accuracy of transmission case, has guaranteed transmission quality, and drive mechanism is stable, reliable, and easy to maintenance, flexible, its structure is suitable for supporting use on various vehicles.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing 1, Fig. 2 the utility model is further described:
The vehicle-mounted transmission case of break-in described in the utility model, the driving gear 8 that slidably is connected on comprising transmission case casing 3, operating grip 1, shift fork 10, splined shaft 9 and being enclosed within splined shaft 9.Under the drive of operating grip 1 and shift fork 10, driving gear 8 moves axially on splined shaft 9, with extraneous gear engagement, power is input on the splined shaft 9.
For satisfying the break-in requirement of power output, be provided with a pair of drive bevel gear 2 between splined shaft 9 in transmission case casing 3 and the output shaft 11, drive bevel gear 2 is meshing with each other, behind power change 90 degree with input on the splined shaft 9, by output shaft 11 outputs.Drive bevel gear 2 engagements are reliable, and it is little, simple in structure, practical to wear and tear.
Be to guarantee the reliability and the transmission accuracy of transmission, reduce or avoid the issuable axial float of bevel gear 2 engagement driving processes, also be provided with axial controlling device at splined shaft 9 two ends.Controlling device comprises end cap 6, cover plate 4, regulates bolt 5 and oil sealing 12.Wherein, end cap 6 is fixed on the transmission case casing 3, and oil sealing 12 is between end cap 6 and transmission case casing 3, end cap 6 is sealed at both ends with splined shaft 9, prevents that the extraneous dust or the grains of sand from entering in the casing, simultaneously, utilize oil sealing 12 to prevent that lubricant oil from exposing, guarantee bearing 7 safety, the reliable use.Cover plate 4 is supported on the bearing outer ring of splined shaft 9, plays the effect of restrictive axes bearing outer-ring.Regulate bolt 5 and be connected on the end cap 6, screw rod stretches in the end cap 6, and its top withstands on the cover plate 4, regulates bolt 5 with cover plate 4 and bearing 7 fixed-site.
In the work, stir shift fork 10 by operating grip 1, driving driving gear 8 moves on splined shaft 9, realize importing being connected of gear with exterior power, driving gear 8 rotations drive splined shaft 9 and rotate, under the transmission of drive bevel gear 2, power changes 90 degree backs by output shaft 11 outputs, has guaranteed the use needs of subsequent drive vehicle.In the long-play process, the back lash appears in 2 of bevel gears, or other reason is when producing axial float, bolt 5 is regulated in corresponding adjustment, the cover plate 4 and bearing 7 positions of corresponding position are moved vertically, the gap when remedying 2 engagements of bevel gear, thus eliminated axial float.Certainly, in the running, also can carry out periodic maintenance, to guarantee the using effect of the vehicle-mounted transmission case of break-in according to the length of service time and the tightness of regulating bolt 5.
