Description

Technical Field

[0001] The utility model belongs to the technical field of four-wheel drive transmission, and particularly relates to a time-sharing four-wheel drive transmission device suitable for a small all-terrain vehicle. Background Art

[0002] In order to improve the off-road performance of the vehicle and solve the problem of the vehicle's ability to pass on roads with poor road conditions and steep slopes, the output shaft of the vehicle's gearbox is generally connected to the input shaft of the transfer case through flanges and other connecting parts, and the transfer case output shaft then outputs power to the front and rear axles to achieve front and rear drive. In other words, the transfer case is a device that distributes the power of the engine, and can output power to the rear axle, or to the front / rear axle at the same time. The input spline shaft of the existing transfer case is generally machined with a retaining ring groove and an O-ring groove, which causes the spline shaft to have a smaller diameter at the retaining ring groove or the O-ring groove, and the torque is correspondingly reduced. During the power transmission process, it is easy to break, causing reliability problems;

[0003] A four-wheel drive transfer case with announcement number "CN202732898U" includes a case body, an end cover, a spline shaft, and a transfer gear, a transmission shaft and a shift gear located in the case body. The two ends of the spline shaft extend out of the two sides of the case body, one end of which is a power input end, and the other end is a rear drive power output end. The spline shaft is located in the middle section of the case body, and its outer diameter is larger than the outer diameters of the two ends of the spline shaft. The four-wheel drive transfer case described in the utility model removes the retaining ring groove and the sealing groove provided on the traditional spline shaft by setting the middle section of the spline shaft to have a larger outer diameter than the two ends of the spline shaft, and uses the steps formed by the middle section and the two ends of the spline shaft to increase the sealing performance of the spline shaft and the case body, which greatly improves the torsional strength of the spline shaft, thereby extending the service life of the transfer case and reducing the cost of use;

[0004] Although the above technical solution has good torque during use, the internal gears are inside the gear box during use, and the overall lubrication is inconvenient. There is a lack of automatic lubrication function during use, and long-term use will cause greater gear wear. The cost of use is low, so it needs to be improved. Utility Model Content
