Problems solved by technology

Also, the bolt groove 3241 of the bevel gear 324 and the bolt groove 41 of the rear wheel shaft 4 must maintain proper play due to the relationship of assembly. When the rear wheel shaft 4 is driven, due to the existence of the aforementioned play, the rear wheel shaft 4 will The shaking amount is greater than the compression amount of the O-ring 42, so that the waterproof function of the O-ring 42 is lost, and then the outer end bearing 44 of the rear axle 4 will be damaged; When passing through the O-ring 42, the teeth on the key groove 41 will easily scratch the surface of the O-ring 42, which will also cause the O-ring 42 to lose its waterproof function; moreover, since the O-ring 42 is arranged on the Between the rear axle 4 and the bevel gear 324, it is not possible to directly judge from the outside whether the O-ring 42 has been assembled or worn out and needs to be replaced, and then the gearbox 30 must be disassembled for inspection, resulting in the O-ring 42 being assembled or damaged. Replacing work-intensive missing

Abstract

The invention provides a waterproof structure of a full terrain vehicle rear wheel shaft. The rear wheel shaft is provided with a gearbox which is provided with a shaft transmission mechanism which transmits the umbrella gear of a shaft; the umbrella gear is slightly vertically engaged with the umbrella gear in the rear wheel shaft gearbox; wherein, the umbrella gear on the rear wheel shaft is extended with a receiving edge to one side of the rear wheel shaft; the receiving edge is extended out of the gearbox; furthermore, the receiving edge is sleeved with a dustproof sleeve; the dust and water can be stopped from entering the internal bearing thus rusting and damaging the bearing by using the dustproof sleeve; furthermore, the invention can reach the efficacy of convenient disassembly, assembly and replacement.

Description

【Technical field】 [0001] The present invention relates to an all-terrain vehicle, in particular to a rear axle of an all-terrain vehicle that axially extends a receiving edge on the bevel gear of the rear axle of the all-terrain vehicle and sets a dustproof sleeve on the receiving edge. Waterproof construction. 【Background technique】 [0002] All-terrain vehicle 1, as shown in Figure 1, is mainly at vehicle frame unit 11, steering gear 12, front wheel 13, seat portion 14, rear wheel 15, and the power unit 2 that provides all-terrain vehicle power source. The front of the vehicle frame 11 is pivotally connected to the steering mechanism 12, and a group of front wheels 13 are arranged below the steering mechanism 12. Behind the steering mechanism 12, a riding portion 14 is arranged on the vehicle frame unit 11. Below the riding portion 14 is power unit 2. The power unit 2, see figure 2 As shown, at least include an engine system 21, and a continuously variable transmission ...
