Problems solved by technology
The action of the shift fork is driven by a link mechanism or a rack mechanism. The link mechanism has shortcomings such as bulky, complex operation, poor flexibility and reliability, so it is rarely used; the rack mechanism is controlled by the output gear of the electronically controlled converter. However, when the ATV is converted from two-wheel drive to four-wheel drive, and the splines of the input and output spindles of the drive box are not synchronized temporarily, the sliding sleeve cannot move, the converter motor is still running, and the output gear is stuck due to If it cannot rotate, it is easy to cause the converter motor to burn out, which not only has poor safety, but also has no guarantee for the performance and service life of the converter.

Embodiment Construction
[0016] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0017] Such as figure 1 , figure 2 As shown, an input gear 2 is installed at one end of the transmission shaft 1, and an output gear 3 is set at the other end. The teeth on the input gear 2 are distributed in an arc shape, the input gear 2 is set on the large diameter section of the stepped bush 8, the bush 8 and the transmission shaft 1 are in clearance fit, and the small diameter section of the bush 8 Set the buffer plate 4, the buffer plate 4 and the output gear 3 are located on the same side of the input gear 2, the buffer plate 4, the bushing 8 and the input gear 2 are fixed by riveting. The rotation of the shaft 1 has good synchronization; when the output gear 3 is stuck, the three can rotate relative to the transmission shaft 1 again.
[0018] Such as figure 1 , figure 2 , image 3 As shown, the buffer piece 4 is provided with a hanging ear 4a ...

The invention relates to a drive converting, buffering and speed-reducing device for a beach cart. An input gear is provided with a buffer plate; the buffer plate is provided with a suspension loop towards an output gear; the middle part of a transmission shaft is fixed with a spring supporting sheet; the spring supporting sheet is provided with a supporting ear towards the input gear; a spring fixing seat is arranged between the buffer sheet and the spring supporting sheet and movably sleeved on the transmission shaft; the outer end of the spring fixing seat is circumferentially limited by the supporting ear of the spring supporting sheet; the spring fixing seat is sleeved with a worm spring; and the inner end of the worm spring is fixed with the spring fixing seat, and the outer end of the worm spring is hung on the suspension loop of the buffer sheet. When the output gear is blocked, the device gives fully play to the buffering and speed-reducing functions so as to improve the reliability for the beach cart converting from two-wheel drive to four-wheel drive, effectively prevent a convertor motor from being burnt out and ensure the service performance and the service life of the convertor. The device has the characteristics of novel design, simple structure, flexible operation, safety, reliability, and the like.
Description
technical field [0001] The invention relates to a beach car driving device, in particular to a beach car drive conversion buffering and deceleration device. 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 beach car is provided by the engine, and the rear end of the engine output shaft is connected to the two rear axle shafts through the rear transmission mechanism, so that the power of the engine is transmitted to the rear axle shaft through the rear transmission mechanism, driving the rear wheels to rotate, and the beach car is completely The car moves forward or backward. Because only the rear wheels of the beach car have driving force, the power is not strong, and t...
