Abstract
The utility model relates to an integral gate-type middle axle assembly with external meshing cylindrical gears. A wheel-side reducer of the integral gate-type middle axle assembly comprises a pair of external meshing cylindrical gears, a driving gear is arranged above a driven gear, accordingly, the ground clearance of an automobile can be increased to the maximum extent, and trafficability is improved. The wheel-side reducer, a brake assembly and an axle housing assembly can be separately mounted, assemblability and maintainability are quite high, and the integral gate-type middle axle assembly is simple in structure, high in carrying capacity, low in cost, fine in weight index, high in transmission efficiency and suitable for medium and heavy off-road vehicles.
Description
Technical field
The utility model relates to automobile and drives the field, refers to a kind of whole gate-type jackshaft assembly particularly.
Background technology
At present, automobile drives the singl-reduction axle that no wheel reduction gear is generally adopted in the field, or adopts planetary gear type hub reduction drive axle.But because the size of the main reduction gear of singl-reduction axle is bigger, cause the car load ground Clearance too small, limited the car load crossing ability; Though the size of the main reduction gear of planetary gear type hub reduction drive axle reduces to some extent; But concerning crossing ability had the military-designed vehicle and cross-country car of requirements at the higher level, its ground Clearance still can not meet the demands, and reduction axle wheel limit in satellite gear limit is because complex structure in addition; Transmission is more; Cause its transmission ratio to descend, degradation of energy strengthens, and its complicated structure also bothers maintenance more.
The utility model content
Deficiency to prior art; The utility model is designed a kind of on the basis of satisfying military-designed vehicle, cross-country car automobile reliability and load-carrying capacity; Improve the whole gate-type jackshaft assembly of car load ground Clearance to greatest extent; And solve its complex structure, be not easy to the problem of dismounting, maintenance.
The top, driven wheel of differential left side of the main reduction gear of the whole gate-type jackshaft of the utility model institute design-calculated assembly is provided with thru shaft; Said main reduction gear is connected in the axle housing; Said axle housing and wheel reduction gear housing link together, and in bevel housing, are provided with interaxle differential, and the mouth of said main reduction gear also is provided with inter-wheel differential; Said inter-wheel differential links to each other with an end of semiaxis, and the other end of said semiaxis is connected with the driving gear of wheel reduction gear.
Said wheel reduction gear is made up of the cylindrical wheel of a pair of external toothing; Comprise driving gear and driven gear; Said driving gear is arranged in the vertical direction of driven gear; Be supported in the said wheel reduction gear housing through pair of bearings, connect with semiaxis, and realize axial locking, location through jam nut through female splines; Driven gear connects with hub spindle through female splines, and the hub spindle inboard head realizes axial locking, fixing through jam nut.
The advantage of the utility model is:
1, wheel reduction gear is made up of a pair of externally-engaged cylindrical gear, by means of the adjustment of its driving gear and driven gear relative position, can adjust the ground Clearance of automobile.In addition driving gear is arranged in the vertical direction of driven gear, the ground Clearance that can increase automobile to greatest extent, improves crossing ability.
2, the utility model assembling capacity and maintainability are very high: wheel reduction gear, brake assembly and axle case assy can be realized packing; And simple in structure, load-carrying capacity is high, cost is lower, weight indicator is good, driving efficiency is high, in being suitable for, heavy-duty off-road vehicle.
Description of drawings
Fig. 1 is the structural representation of whole gate-type jackshaft assembly.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe in detail.
As shown in Figure 1; The top, driven wheel of differential 15 left sides of the main reduction gear 13 of the whole gate-type jackshaft of the utility model institute design-calculated assembly is provided with thru shaft 8; Said main reduction gear 13 passes through bolted connection in axle housing 7; Said axle housing 7 is preferably press welding axle housing; Said press welding axle housing 7 links together through welding (or bolted connection) with wheel reduction gear housing 2, in main reduction gear 13 housings, is provided with the interaxle differential 9 that a pair of cone bearing supports, and the mouth of said main reduction gear 13 is provided with inter-wheel differential 14; The axle side gear of inter-wheel differential 14 is connected with an end of semiaxis 8 through spline, and the other end of said semiaxis 8 and the driving gear of wheel reduction gear 4 are connected through spline.
Said wheel reduction gear is made up of the cylindrical wheel of a pair of external toothing; Comprise driving gear 4 and driven gear 12; Said driving gear 4 is arranged in the vertical direction of driven gear 12; Be supported in the said wheel reduction gear housing 2 through pair of bearings 3, be connected with semiaxis 6, and realize axial locking, location through jam nut through female splines; Said driven gear 12 is connected with hub spindle 11 through female splines, and hub spindle 11 inboard head realize axial locking, fixing through jam nut.Said hub spindle 11 is connected with Hub assembly 1 through the end face tooth, and is fixed by bolts on the Hub assembly 1; Said Hub assembly 1 passes through bolted connection with the brake disc 10 of plate disc brake.
Wheel reduction gear is made up of a pair of externally-engaged cylindrical gear, by means of the adjustment of its driving gear 4 and driven gear 12 relative positions, can adjust the ground Clearance of automobile.In addition driving gear 4 is arranged in the vertical direction of driven gear 12, the ground Clearance that can increase automobile to greatest extent, improves crossing ability.
The wheel reduction gear of the utility model, brake assembly and axle case assy are formed can realize packing; Assembling capacity and maintainability are very high; And simple in structure, load-carrying capacity is high, cost is lower, weight indicator is good, driving efficiency is high, in can being suitable for, heavy-duty off-road vehicle.
Claims (2)
1. whole gate-type jackshaft assembly; Comprise main reduction gear, thru shaft, axle housing, interaxle differential, inter-wheel differential, wheel reduction gear housing, semiaxis, wheel reduction gear; It is characterized in that: said thru shaft is arranged on the top, driven wheel of differential left side of main reduction gear, and said main reduction gear is connected in the axle housing, and said axle housing and wheel reduction gear housing link together; In the housing of main reduction gear, be provided with interaxle differential; Mouth at main reduction gear is provided with inter-wheel differential, and said inter-wheel differential links to each other with an end of semiaxis, and the other end of said semiaxis is connected with the driving gear of wheel reduction gear.
