Multifunctional speed changer with center brake and power takeoff

Abstract

The invention belongs to the field of gearboxes, and relates to a truck gearbox, especially a multifunctional gearbox with a central brake and a power take-off, which is used in the preparation of trucks; it solves the difficulty of shifting gears in the first and second gears, and there are abnormal noises. Braking is not safe and stable when parking on a slope. The main structure includes clutch housing, intermediate housing, rear housing, input shaft assembly, output shaft assembly, intermediate shaft assembly, central brake, shift fork Shaft assembly, idler shaft assembly, gear selection mechanism assembly, clutch, release bearing and power take-off; the first and second gear synchronizers and the third and fourth gear synchronizers all adopt double-cone structures, and the parking brake adopts a central brake. It makes the braking safer and more stable when parking on a slope; on the other hand, it is equipped with a power take-off, which can realize auxiliary functions such as vehicle tipping and self-unloading; its overall structure is reasonable, high in safety performance, low in preparation cost, energy-saving and environmentally friendly, and has low gear shift resistance. Small, easy to operate, with good economic benefits and broad market prospects.

Description

[0001] Technical field: [0002] The invention belongs to the field of gearboxes, and relates to a truck gearbox, in particular to a multifunctional gearbox with a central brake and a power take-off, which is used in the preparation of trucks. [0003] Background technique: [0004] The transmission changes the torque and speed by several pairs of gears with different transmission ratios, mainly by the deceleration and torque increase of the gear transmission. The two gears mesh with each other, and one tooth of the driving gear pushes one tooth of the driven gear. For example, the number of teeth of the driving pinion is 8, and the number of teeth of the driven gear is 16. The pinion rotates 1 circle, and the bull gear can only rotate half a circle. Therefore A pair of gear transmissions can achieve the effect of reducing the speed. At the same time, the force on the contact surface of the teeth of the two gears is equal. According to the principle of "the force multiplied by...
