Embodiment Construction
[0022] according to figure 1 Shown, the present invention is on the basis of existing transmission gear box, is particularly provided with a reverse gear in the transmission gear box. The gear has a central gear 19 driven by a motor through the gear set to drive the gear train of the reverse gear. The H axis of the central gear 19 runs through the reverse gear. On the inner H axis of the reverse gear, gears 21 and 20 are arranged at intervals. , gear 22, the inner bottom of the reverse gear is provided with the internal gear 27 that can slide, and the shift lever K that stretches out is arranged on the reverse gear inner top, and the shift fork that can stir the gear 27 is arranged on the shift lever K, and the gear 24 and Propeller J shaft links to each other in water, and sector gear 26 links to each other with self-rescue winch I shaft. The gear 21 and the gear 23 of the present invention are two conjoined gears, and the gear 22 and the gear 25 are two conjoined gears. Th...

The invention relates to a reverse gear unit in a change gear box, in particular to a change gear box for an amphibious automobile. The invention discloses a reverse gear unit arranged in a change gear box. The reverse gear unit comprises an annular periphery consisting of inter-joggled gear sectors 23, 24, 25, 26. The reverse gear unit is provided with a central gear 19 for driving the gear trainof the reverse gear unit, which is driven by a motor through a gear cluster or is directly driven by the motor. The H shaft of the central gear 19 is traverse threaded through the reverse gear unit,and the segment of the H shaft in the reverse gear unit is provided with a gear 21, a gear 20 and a gear 22, which are arranged at intervals. An inner gear 27 which can glide is arranged in the lowerpart of the reverse gear unit; a shifter lever K extended from outside is arranged in the upper part of the reverse gear unit; the shifter lever K is provided with a shifting yoke which can shift thegear 27; the gear 24 is connected with a screw propeller J shaft in water. The gear sector 26 is connected with a self-recovery winch I-shaft. The engine of the invention is connected with the outputpower of the multifunction gear box to complete the functions of overwater travel and a worm wheel self-recovery windlass, thus ensuring the engine to keep strong drive force all along.
Description
technical field [0001] The invention relates to a gear box for an amphibious vehicle, in particular to an amphibious vehicle with water walking and a self-rescue winch. Background technique [0002] At present, general amphibious vehicles have the function of traveling on water. The function of traveling on water is adjusted and implemented by tire propulsion by a gear box. The function of traveling on water also has propeller propulsion. Some engineering vehicles and emergency vehicles are equipped with a self-rescue winch system, but this system is arranged outside the wheel propulsion system, so the operation must be complicated and the operation actions are many, which makes the driver feel inconvenient and inflexible. Contents of the invention [0003] The purpose of the present invention is to provide a reverse gear in the transmission gearbox, which is the power output by the multifunctional gearbox connected to the engine, to complete the functions of water walking...
