Description
[technical field]
The utility model relates to a kind of automobile axle structure, relates in particular to a kind of whole drive-type automobile axle structure.
[background technology]
Traditional integral drive-type automobile axle structure generally includes a propulsion source (being generally motor), a universal driving device, a change speed gear box, a traditional retarder, a diff, two-semiaxle, two bridge tubes and a bridge bag; Wherein propulsion source is connected with universal driving device via change speed gear box and through an axle drive shaft; The tradition retarder is connected with universal driving device; Two bridge tubes are sheathed on the two-semiaxle surface respectively; The tradition retarder all is connected through inside and outside gear mesh with semiaxis with diff, diff, and in traditional retarder and diff all be wrapped in by the bridge bag; When work; Propulsion source carries out one-level speed change with power transmission to change speed gear box through the mouth of self; Turn round to realize that first reduction of speed increases, change speed gear box reaches traditional retarder with moment of torsion through axle drive shaft and universal driving device afterwards, and transmits once more rev down, increases moment of torsion through this tradition retarder in-to-in gear cluster; Then diff turns round under the drive of traditional retarder, thereby and diff with rotating speed and torque distribution to semiaxis drive wheel.
To sum up can know; The location arrangements of traditional retarder, diff, semiaxis and propulsion source in the traditional integral drive-type automobile axle structure is separated by far away; The middle need adopts transmission devices such as axle drive shaft and universal driving device to connect through change speed gear box one-level speed change again; Such structure, not only take up space bigger, cost is higher, thereby and cause driving efficiency relatively low because of the course of torque transfer is long.
[utility model content]
The utility model technical matters to be solved is to provide a kind of whole drive-type automobile axle structure, has not only improved utilization of space, cost-cutting, but also has improved the efficient of transmission.
The utility model solves the problems of the technologies described above through following technical scheme: a kind of whole drive-type automobile axle structure; Comprise a diff, two-semiaxle, two bridge tubes, a Qiao Bao and a front end be provided with the propulsion source of output shaft, and one be positioned at the bridge bag central reducer unit; This central reducer unit and diff are connected with a joggle; Said two bridge tubes are sheathed on the surface of two-semiaxle respectively, and two these bridge tubes are connected through the bridge bag; Two mouths of said diff are connected with a joggle with two-semiaxle respectively, and this diff is positioned at the bridge bag, and the front end of said propulsion source docks with the attachment face of bridge bag, and the rear end of this propulsion source is connected with bridge tube, and said output shaft is connected with central reducer unit.
Further, said output shaft is connected through spline with central reducer unit.
Further, said propulsion source is a motor.
Further, the front end of said propulsion source is provided with threaded mounting hole, and this threaded mounting hole docks interlocking through bolt with the attachment face of bridge bag.
Further, the rear end of said propulsion source is connected with bridge tube through a mounting bracket.
The beneficial effect of the whole drive-type automobile axle of the utility model structure is: through be arranged at propulsion source on the bridge tube, propulsion source directly is connected with central reducer unit via the output shaft of self; Thereby need not traditional diff, axle drive shaft and universal driving device, make the utility model improve utilization of space, cost-cutting; And, thereby make the very short efficient that improves transmission of course of torque transfer because of the adjacent setting of propulsion source with central reducer unit.
[description of drawings]
Combine embodiment that the utility model is done further to describe with reference to the accompanying drawings.
Fig. 1 is the scheme drawing of the whole drive-type automobile axle of the utility model structure.
[specific embodiment]
See also Fig. 1; The whole drive-type automobile axle of the utility model structure; Comprise a diff 1, two-semiaxle 2, two bridge tubes 3, be located at bridge bag (not shown) between two bridge tubes 3, propulsion source 4 that a front end 41 is provided with output shaft (not shown), and one be positioned at the bridge bag central reducer unit 5; This central reducer unit 5 is connected with a joggle with diff 1, and said two bridge tubes 3 are sheathed on the surface of two-semiaxle 2 respectively, and two these bridge tubes 3 are connected through the bridge bag; Two mouths of said diff 1 are connected with a joggle with two-semiaxle 2 respectively; And this diff 1 is positioned at the bridge bag; The front end 41 of said propulsion source 4 docks with the attachment face of bridge bag, and the rear end 42 of this propulsion source 4 is connected with bridge tube 3, and said output shaft is connected with central reducer unit 5.Wherein, output shaft can be connected through spline with central reducer unit 5; The comparatively common motor of propulsion source 4 general employings; The reduction ratio of central reducer unit 5 is compared with traditional retarder; In addition, in the present embodiment, the front end 41 of propulsion source 4 is provided with threaded mounting hole (not shown), and this threaded mounting hole generally forms the state of interlocking that docks through bolt (not shown) with the attachment face of bridge bag; The rear end of propulsion source 4 is connected with bridge tube 3 through mounting bracket 6.
The utility model is when using: propulsion source 4 is given central reducer unit 5 through the mouth of self with power transmission; Power is via central reducer unit 5 rev downs, increase moment of torsion; Then diff 1 turns round under the drive of central reducer unit 5; And diff 1 is with rotating speed and torque distribution to semiaxis 2, and the wheel of automobile rotates under the drive of semiaxis 2 afterwards.
To sum up; The whole drive-type automobile axle of the utility model structure and traditional comparing; It is arranged at propulsion source 4 on the bridge tube 3; And directly be connected with central reducer unit 5 through the output shaft of propulsion source 4 self, thereby need not traditional diff, axle drive shaft and universal driving device, make the utility model improve utilization of space, cost-cutting; And, thereby make the very short efficient that improves transmission of course of torque transfer because of propulsion source 4 and central reducer unit 5 adjacent settings.
