Problems solved by technology
Because only the rear wheels of the beach car have driving force, the power is not strong, and the passability is poor. When the beach car is climbing a very inclined slope, it is difficult to run; Slipping makes it difficult to travel, and then there are problems such as stalling

Embodiment Construction
[0015] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0016] Such as figure 1 As shown, the internal structure of the engine 1 is the prior art, and will not be repeated here. The rear end of the output shaft of the engine 1 is connected with the two rear axle shafts 2 through the rear transmission mechanism. The rear transmission mechanism is composed of connecting shaft 19, the first universal joint spline sleeve 20, the universal joint spline shaft 21, the second universal joint spline sleeve 22 and the rear drive box 23, wherein the connecting shaft 19 is supported on the On the engine 1 casing, the front end of the connecting shaft 19 is docked and fixed with the rear end of the output shaft of the engine 1, and the tail end of the connecting shaft 19 passes through the rear end face of the engine 1 casing, and is connected with the first universal joint spline sleeve 20 The front end of the first universa...

The invention relates to a driving device for two-wheel and four-wheel a beach cart. The front end of an output shaft of an engine is connected with the tail end of a front transmission shaft; the front end of the front transmission shaft is connected with an input main shaft spline of a front driving box; an output main shaft of the front driving box is provided with a bevel gear; the bevel gear is meshed with an input spiral bevel gear of a differential device; two output shaft sleeves of the differential device are connected with two front axle semi-shafts respectively; the input main shaft and the output main shaft of the front driving box are provided with outer splines with the same shape and size, and the outer spline of the output main shaft is sleeved with a spline sliding sleeve; a shift fork of a shift fork mechanism is clamped into an annular groove on the outer surface of the spline sliding sleeve; and a handle of the shift fork mechanism is positioned on the outer surface of the front driving box and hinged with a cart frame of the beach cart. The device has the characteristics of novel design, easy implement, wide range of application, and the like and can make the beach cart select the two-wheel drive or the four-wheel drive according to the actual situation. The two-wheel drive and the four-wheel drive can be conveniently converted and simply operated so as to greatly improve the dynamic performance and the trafficability of the beach cart.
Description
technical field [0001] The invention relates to a beach car, in particular to a two-wheel and four-wheel drive device for the beach car. Background technique [0002] At present, most of the ATVs on the market are driven by the rear wheel drive to move the front wheels (the front wheels have no direct power). The two front wheels of the beach car are installed on the frame through the suspension mechanism, and the two rear wheels are set on the respective rear axle shafts. The power of the ATV is provided by the engine. The rear end of the engine output shaft is connected to the front end of the universal joint spline shaft through the connecting shaft and the first universal joint spline sleeve, and the rear end of the universal joint spline shaft is connected through the second million joint spline shaft. The knuckle spline sleeve is connected with the input shaft of the rear drive box, and the two output shaft sleeves of the rear drive box are respectively connected with...
