Problems solved by technology

A miniature car with only two rear-wheel drives cannot provide sufficient ground driving force when passing a road with a low adhesion coefficient; especially when passing through a muddy or muddy section, the driving wheels are prone to sinking into mud or slipping and cannot be driven. Thereby affecting the passability of the car and bringing great inconvenience to people's travel

Embodiment Construction

[0026] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0027] As shown in FIG. 1 , FIG. 2 and FIG. 3 , the gearbox 2 is installed at the rear end of the engine 1 , and the input shaft of the gearbox 2 is connected with the output shaft of the engine 1 . The transfer case is located at the tail of the gearbox 2, and is formed by docking the transfer case front cover 7 and the transfer case rear cover 8, and the two are fixed by bolts. The front part of one side of the transfer case front cover 7 is integrally formed with a hollow truncated cone, and the front end face of the other side of the transfer case front cover 7 is adapted to the shape and size of the tail end face of the gearbox 2, so that the splitter can be separated by bolts. The moving case is fixed on the gearbox 2. The output shaft 3 of the gearbox 2 passes through the transfer case and protrudes from the hollow cone formed integrally at the rear o...

Abstract

The invention relates to a power device of two-wheel drive and four-wheel drive of a mini car. A driving gear on an output shaft of a gearbox is positioned in a transfer case; a pinion is arranged on the rear of the output shaft of the transfer case through a bearing; the front end of the output shaft of the transfer case extends from the front of a front cover of the transfer case and is connected with the rear of a front reducer; a front axle half shaft is arranged on the left side and the right side of the front of the front reducer; synchronizer engaging teeth are sleeved and arranged on a ring boss of the front of the pinion in the transfer case; a synchronizer ring is looped on the synchronizer engaging teeth; synchronizer fixing teeth are arranged on the output shaft of the transfer case on the front side of the synchronizer ring; a synchronizer engaging teeth sleeve is sleeved and arranged on the synchronizer fixing teeth; a roller of a fork-lever mechanism is inserted in a ring groove of external surface of the synchronizer engaging teeth sleeve. The power device can cause the mini car to select the two-wheel drive or the four-wheel drive according to practical situation, and has convenient switch between the two-wheel drive and the four-wheel drive and simple operation, which greatly enhances gradeability of the mini car and effectively improves passing ability of the car.

Description

technical field [0001] The invention relates to a miniature car, in particular to a two-wheel drive and four-wheel drive power device for the miniature car. Background technique [0002] At present, miniature cars generally use the rear wheel drive mode, that is, the power of the engine is first transmitted to the gearbox, and then the output shaft of the gearbox is transmitted to the rear reducer and the rear axle shaft through the rear drive shaft to drive the rear wheels to rotate. , the whole vehicle travels forward or backward. A miniature car with only two rear-wheel drives cannot provide sufficient ground driving force when passing a road with a low adhesion coefficient; especially when passing through a muddy or muddy section, the driving wheels are prone to sinking into mud or slipping and cannot be driven. Thereby affecting the passability of automobile, brings great inconvenience to people's travel. Contents of the invention [0003] The technical problem to b...
