Abstract
The invention discloses a kind of main gearbox assembly allowing two ends to input, be characterized in, comprise front end input shaft (2) and rear end input shaft (7), outside it, establish front end input flange (1) and rear end input flange (6) respectively; Front end input shaft (2) is connected with active cylindrical gears (3) by spline, and initiatively cylindrical gears (3) engages with the driven cylindrical gear (4) on main cone (5); Rear end input shaft (7) is connected with differential lock (8) by spline, and rear end input shaft (7) is contacted by shaft hole matching with active cylindrical gears (3), there is no and is rigidly connected; This main gearbox assembly allows two ends input, the power of front end is provided by motor, gearbox, the power of rear end is provided by speed reducer, under the prerequisite not having clutch, require when power is inputted by front end, output that rear end is unpowered, when power is inputted by rear end, allow the dynamic output in front end, now only need gearbox to hang neutral.
Description
Technical field:
The present invention relates to vehicle bridge technical field, specifically a kind of main gearbox assembly allowing two ends to input; Be mainly used in mining vehicle bridge, Special-truck-axle.
Background technique:
At present, for special purpose vehicle, as Bridge Erector car, car load only has a ransaxle, in the process of building bridge, due to speed restriction, needs to drive car load to move ahead with speed reducer; After the complete bridge of frame, due to spatial constraints, do not allow to turn around, now need motor, gearbox to drive car load to leave.
During speed reducer drive car load, gearbox can be hung neutral, so allow the one end connecting gearbox to rotate; When motor, gearbox drive car load, drive the axle of speed reducer not allow to rotate, a clutch can be saved like this.
The main gearbox assembly now used is one end input, even if jackshaft allows from two ends input, is also the unpowered output of one end skidding the other end, or two ends are rotated after hanging up differential lock simultaneously, but because there is the existence of differential mechanism, when hanging up differential lock turning, easily cause differential mechanism to beat tooth.
Summary of the invention:
The object of the invention is the deficiency overcoming above-mentioned prior art, and a kind of main gearbox assembly allowing two ends to input is provided; Mainly solve the problem that the input of existing main gearbox assembly one end can not meet performance requirement.
Technological scheme of the present invention is: a kind of main gearbox assembly allowing two ends to input, and its special way is, comprises front end input shaft and rear end input shaft; Peripheral hardware front end, the front end input flange of described front end input shaft, peripheral hardware rear end, the rear end input flange of described rear end input shaft; Front end input shaft is connected with active cylindrical gears by spline, and initiatively cylindrical gears engages with the driven cylindrical gear on main cone; Rear end input shaft is connected with differential lock by spline, and rear end input shaft is contacted by shaft hole matching with active cylindrical gears, there is no and is rigidly connected.
Compared with the prior art a kind of main gearbox assembly allowing two ends to input of the present invention has outstanding substantive distinguishing features and remarkable progress: 1, allow two ends input, remove differential mechanism, retain differential lock, when power is inputted by front end, tire is reached by spline, gear etc., and rear end is not now rigidly connected with front end, so there is no Power output; When power is inputted by rear end, hang up differential lock, power also can reach tire by spline, gear etc. smoothly, and allows the dynamic output in front end, now only needs gearbox to hang neutral; 2, its structure is simple, when not having clutch, controls the power of rear end smoothly.
Accompanying drawing illustrates:
Fig. 1 is outline drawing of the present invention;
Fig. 2 is structural representation of the present invention.
Wherein: 1 front end input flange, 2 front end input shafts, 3 initiatively cylindrical gears, 4 driven cylindrical gear, 5 main cones, 6 rear end input flanges, 7 rear end input shafts, 8 differential locks.
Embodiment:
In order to Comprehension and Implementation better, provide specific embodiment below in conjunction with accompanying drawing and describe the present invention in detail; Illustrated embodiment, only for explaining the present invention, is not for limiting the scope of the invention.
Embodiment 1, see Fig. 1,2, selects front end input shaft 2 and the rear end input shaft 7 of appropriate size, installs front end input flange 1, install rear end input flange 6 outside the rear end of rear end input shaft 7 outside the front end of front end input shaft 2; Be connected with active cylindrical gears 3 by spline by front end input shaft 2, initiatively cylindrical gears 3 engages with the driven cylindrical gear 4 on main cone 5, and power reaches tire the most at last; Rear end input shaft 7 is connected with differential lock 8 by spline, rear end input shaft 7 is contacted by shaft hole matching with active cylindrical gears 3, there is no and be rigidly connected, when differential lock 8 moves to the left side, can be connected with rear end input shaft 7 with active cylindrical gears 3 by spline simultaneously, form the main gearbox assembly of permission two ends of the present invention input; Be connected with gearbox, motor by its front end input flange 1 during use, rear end input flange 6 is connected with speed reducer.
A kind of main gearbox assembly allowing two ends to input of the present invention, working principle:
When power is inputted by front end, the transmitting procedure of power is as follows: the power provided by motor, gearbox, reach front end input flange, power is reached front end input shaft by spline by front end input flange, front end input shaft drives initiatively cylindrical gears by spline, and initiatively cylindrical gears is by engaging with driven cylindrical gear, by transmission of power to driven cylindrical gear, driven cylindrical gear drives main cone to rotate by spline, and last power reaches tire; In the process, initiatively cylindrical gears and rear end input shaft are not rigidly connected, so rear end input shaft does not have Power output;
When power is inputted by rear end, the transmitting procedure of power is as follows: when providing power to be inputted by rear end by speed reducer, need with differential lock will initiatively cylindrical gears and rear end input shaft by together with spline joint, power reaches rear end input flange, power is reached rear end input shaft by spline by rear end input flange, rear end input shaft drives initiatively cylindrical gears by the spline joint of differential lock, initiatively cylindrical gears is by engaging with driven cylindrical gear, by transmission of power to driven cylindrical gear, driven cylindrical gear drives main cone to rotate by spline, last power reaches tire, in the process, initiatively power can be reached front end input shaft and reach front end input flange again by cylindrical gears.
