A front driving axle assembly of a light-duty off-road vehicle comprises a front driving axle and an independent clutch electrical component, wherein the clutch electrical component is assembled on aclutch casing of the front driving axle via a screw rod. The clutch electric component comprises a case body and a case cover, a motor is arranged in the case body, a power output shaft of the motor is provided with a worm, a duplex gear shaft is arranged in the case body, a worm gear and a gear are arranged on the duplex gear shaft, a gear shaft with a gear wheel and a gear is further arranged inthe case body, a rack shaft is arranged in a rack shaft hole on the case body, a pin hole is arranged on the rack shaft, and a shift fork is mounted on the rack shaft via a pin. In the technical scheme, the worm is meshed with the worm gear, the gear on the duplex gear shaft is meshed with the gear wheel, and then the gear on the gear shaft is meshed with the rack shaft in the rack shaft hole onthe case body.
Description
Technical field
The utility model relates to a kind of front driving axle assembly of transportation means, particularly a kind of light off-road vehicle front driving axle assembly.
Background technology
The light off-road vehicle front driving axle assembly of domestic production at present has and can not carry out two and drive the AWD that switches with 4 wheel driven, have by two of pneumatic (vacuum actuator) driving and drive the super 4 wheel driven that selects that switches with 4 wheel driven, also there is two of motorized motions to drive the super 4 wheel driven that selects that switches with 4 wheel driven, also has and be with two of manual or automatic hub clutch to drive the optional 4 wheel driven that switches with 4 wheel driven.But the AWD car resistance is big, oil consumption is high; The optional 4 wheel driven of belt wheel limit power-transfer clutch has increased complete vehicle weight and unsprung weight; Manually selectable 4 wheel driven Taiyuan beginning, automatic poor reliability; Pneumatic surpassing selects the 4 wheel driven source of the gas to take from engine intake manifold, complex structure, be used as power and be subjected to engine operating state to influence that (degree of vacuum was big when rotating speed was high greatly, thereby suction is big), declutch shift shaft assembles with shift fork and propons, connect the vacuum actuator axle be contained on the front axle housing by straight pin, a whole set of pts system takes up space bigger, allows the car load difficult arrangement; Electrically operated because of axle housing and power-transfer clutch become one, structure is complicated, assembling and maintenance are all difficult, and cost is higher relatively.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of later-model light off-road vehicle front driving axle assembly is provided.
The technical solution of the utility model is: a kind of light off-road vehicle front driving axle assembly, and it comprises a front driving axle and an independent clutch electric assembly, the clutch electric assembly fits on the clutch-bell cover of front driving axle by screw.
Described clutch electric assembly comprises a casing and Box Cover, is provided with a motor in casing, and the power take-off shaft of motor is provided with a worm screw; Be provided with a duplex tooth axle in casing, duplex tooth axle is provided with a worm gear and gear; In casing, also be provided with the gear wheel shaft of a band big gear wheel and gear; Be provided with a toothed rack axle in the tooth bar axis hole on casing, rack shaft is provided with a pin hole, and shift fork is installed on the rack shaft by pin.
In present design, the worm and wheel engagement, gear on the duplex tooth axle and big gear wheel engagement, the gear on the gear wheel shaft meshes with the rack shaft that is installed in the casing upper rack axis hole again.
The principle of work of clutch electric assembly is: motor is accepted to rotate after the closure instruction of (or disengagement), the worm gear that drives on the duplex tooth by the worm screw on the motor shaft rotates, rotate by the big gear wheel on the gear driven gear wheel shaft on the duplex tooth again, gear on the gear wheel shaft and then rotates, realize axial motion by the gear driven rack shaft on the gear wheel shaft then, separate with clutch gear and connect by main shaft by the shift fork that is installed on the rack shaft at last, thereby realize constant speed semiaxis and main reduction gear from close, allow automobile carry out two switchings of driving with 4 wheel driven.
The utility model compared with prior art has following characteristics:
1, the clutch electric assembly directly is assemblied on the clutch-bell cover, and shift fork is installed on the rack shaft by pin, and diaxon is simplified to one, compact conformation, in light weight, good reliability.
2, power-transfer clutch, clutch electric assembly, retarder, front axle housing etc. are independent separately, assembling and maintenance are all fairly simple, cost is relatively low, only need to rotate motor switch at operator's compartment, electric assembly just can drive power-transfer clutch closure/disengagement f-w-d, both guarantee the cross-country traveling ability of complex road surface, and also can guarantee traveling comfort and low consumption constantly at a high speed.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of clutch electric assembly;
Accompanying drawing 3 is the left view of accompanying drawing 2.
The specific embodiment
As shown in drawings: a kind of light off-road vehicle front driving axle assembly, it comprises a front driving axle 1 and an independent clutch electric assembly 4, clutch electric assembly 4 fits on the clutch-bell cover 2 of front driving axle 1 by screw.Described clutch electric assembly 4 comprises a casing 11 and Box Cover 12, is provided with a motor 5 in casing 11, and the power take-off shaft of motor 5 is provided with a worm screw 6; Be provided with a duplex tooth axle 7 in casing 11, duplex tooth axle 7 is provided with a worm gear 13 and gear 14; In casing, also be provided with the gear wheel shaft 9 of a band big gear wheel 8 and gear 15; Be provided with a toothed rack axle 10 in the tooth bar axis hole on casing 11, rack shaft is provided with a pin hole 16, and shift fork 3 is installed on the rack shaft 10 by pin.
In present design, worm screw 6 and worm gear 13 engagements, gear 14 on the duplex tooth axle 7 and big gear wheel 8 engagements, the gear 15 on the gear wheel shaft 9 mesh with the rack shaft 10 that is installed in the casing 11 upper rack axis holes again.
