Description

Technical Field

[0001] The utility model relates to the technical field of off-road vehicles, in particular to a driving assembly structure of an off-road vehicle. Background Art

[0002] The traditional off-road vehicle driving assembly consists of a driving motor and a single-stage or multi-stage planetary reducer. The planetary bracket of the reducer is fixed on the motor housing to form an integral connection structure, and the motor shaft and the reducer are coaxial or splined to each other. The reducer transmits power to the outside by rotating the housing connected to the inner gear ring of the planetary reducer. This integral structure reducer and motor are interdependent, and neither unit can be removed independently, otherwise the driving function will fail. If any unit of the motor or reducer fails during use, it is impossible to quickly replace or repair a single unit, and the entire unit can only be disassembled for repair or replacement. Utility Model Content

[0003] In view of the defects of the above-mentioned prior art and in order to realize the rapid replacement of the planetary reducer and the motor of the off-road vehicle driving assembly, a split structure of the reducer and the motor is invented, that is, the reducer is an independent integral unit, which can be disassembled independently and can be quickly installed as a whole with the motor by bolts, so as to solve the problems raised in the above-mentioned background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A non-road vehicle driving assembly structure includes a driving motor and a planetary reducer, wherein the planetary reducer includes a reducer housing and a first-stage sun gear of the reducer, a plurality of reducer connecting brackets are evenly arranged on the outside of the reducer housing, a bolt connecting hole is arranged on the reducer connecting bracket, and a positioning stop matched with the bolt connecting hole is arranged on the reducer connecting bracket at the bolt connecting hole, the driving motor includes a motor housing and an internal spline motor shaft, a threaded hole is arranged on the motor housing, and the motor housing can be quickly installed with the threaded hole of the motor housing by connecting bolts.

[0006] Preferably, the internal spline motor shaft drives the planetary reducer to operate through the first-stage sun gear of the reducer.

[0007] Preferably, a bearing is fixedly mounted on the planetary reducer, and the bearing is fixedly connected to the shaft wall of the internal spline motor shaft.

[0008] Preferably, the planetary reducer is provided with an oil seal that matches the internal spline motor shaft.

[0009] Preferably, a clutch knob is fixedly provided on the planetary reducer.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The driving assembly structure of the off-road vehicle is designed to have a driving motor and a planetary reducer as two independent unit structures, which can be installed separately or as a whole during installation. When any unit fails, it is only necessary to replace the corresponding unit assembly, and there is no need to dismantle the entire unit for repair or replacement like the integral drive assembly structure, which greatly improves the convenience of maintenance and can effectively reduce the maintenance cost. At the same time, this type of reducer can quickly match multiple specifications of motors to meet the different needs of different vehicles, greatly increasing the interchangeability of the product. At the same time, when the drive assembly is processed and produced, it is only necessary to assemble the motor and reducer units separately, and then assemble the two. This method is convenient to process and easy to produce. Compared with the integral structure, it is lighter and faster to assemble, and the labor intensity of workers is lower.
