Power takeoff and vehicle with same

Abstract

The invention discloses a vehicle and a power takeoff thereof. The power takeoff comprises a shell, an input mechanism, a driven mechanism, an output mechanism and a driving mechanism. The input mechanism is mounted on the shell. The driven mechanism is connected with the input mechanism. The output mechanism comprises an output shaft, a first output gear, a second output gear and a gear sleeve, the first output gear sleeves the output shaft in an empty mode and is connected with the input mechanism, the second output gear sleeves the output shaft in an empty mode and is connected with the driven mechanism, and the gear sleeve is connected to the output shaft and moves among a first position, a second position and a third position. The gear sleeve is connected with the first output gear to enable the output shaft to rotate reversely when located at the first position, and is connected with the second output gear to enable the output shaft to rotate forwards when located at the second position. The driving mechanism comprises an elastic part and a driving part, the driving part drives the gear sleeve to move towards the first position and the second position, and the elastic part provides force for keeping the gear sleeve at the third position for the gear sleeve. According to the power takeoff, bidirectional power output can be achieved, and the power takeoff has the advantages of being high in reliability, stable in meshing, long in service life and the like.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a power take-off and a vehicle with it. Background technique [0002] The power take-off in the related art usually includes an input mechanism and an output mechanism, and the transmission connection between the input mechanism and the output mechanism is used to realize power transmission. However, the output mechanism can only realize one-way output, and the application occasions are few and the function is single. [0003] Therefore, some power take-offs are equipped with a driven structure and a driving mechanism, and the output mechanism includes a gear sleeve and two output gears, and the gear sleeve is driven by the driving mechanism to mesh with different output gears to change the rotation direction of the output mechanism. The power take-off can realize two-way rotation, which greatly expands the application range of the power take-off. However, the position fixation...

Problems solved by technology

However, the position fixation of the gear sleeve is poor, and it is prone to shaking. When the power take-off does not need power output, the gear sleeve may accidentally contact with the output gear, which will cause the power output of the power take-off, and the reliability is low. Moreover, the drive When the mechanism drives the toothed sleeve and the output gear to mesh, the moving speed of the toothed sleeve may be relatively fast, resulting in collision and serious wear between the geared sleeve and the output gear, which affects the stability and service life of the geared sleeve and the output gear.
