Multi-forward and multi-backward gear gearbox provided with improved structure and applied to garden machinery

Abstract

The invention provides a multi-forward and multi-backward gear gearbox provided with an improved structure and applied to garden machinery. The gearbox comprises a power input end, a first power output end and a second power output end, wherein the first power output end is connected with a walking mechanism through a walking transmission mechanism, the second power output end is connected with aworking module through a quick-release power output part, a forward-backward multi-gear adjusting structure is arranged between the power input end and the first power output end, and power connectionor disconnection is realized on the second power output end through a power closing and separating control mechanism. The gearbox is wide in applicability, a normally-opened or normally-closed clutchcan be selectively installed according to customer requirements, the forward-backward multi-gear adjusting structure is arranged so that the forward and backward speed adjusting range of at least four gears is achieved, the adjustable speed range of the gearbox is increased, and the gearbox is applicable to different preposed operating units; and the gearbox is further provided with a double-output tire shaft and a differential mechanism so as to adapt to various road conditions, and steering is convenient.

Description

technical field [0001] The invention belongs to the technical field of gear boxes, in particular to a gear box with an improved structure and multiple forward and backward gears applied to garden machines. Background technique [0002] For the current gearboxes, most of them are three-forward and three-reverse gears, such as Chinese utility model patent No. 201621194911.3, which is named: full hydraulic control multi-gear construction machinery gearbox; a gear with three forwards and three reverses is proposed The gearbox has a complex internal structure, specifically: the transmission mechanism includes a forward clutch shaft (4), a reverse clutch shaft (7), an intermediate clutch shaft (10), a forward Pangu gear (5), and a reverse Pangu gear (8), the first gear Pangu gear (14), the second gear Pangu gear (17), the third gear Pangu gear (18) and the transmission gear (16); the input gear (1) is simultaneously with the forward gear Pangu gear (5) , the reverse gear Pangu ge...

Problems solved by technology

[0004] Secondly, the existing gearboxes have the following defects. They cannot be used for a variety of horsepower engines, and the clutch has poor applicability, and often only one clutch can be used; there are few walking gears and the speed adjustment range is limited; High to prevent deadlock; the structure is too complex
