Abstract
The utility model relates to a rear axle of a self-propelled mower, which comprises two half shafts arranged between two rear wheels, wherein, a differential mechanism is arranged between the two half shafts, thereby, a reverse mechanism and a braking device are successively arranged on the differential mechanism. Compared with the existing similar products, the capability of the rear axle of a self-propelled mower is excellent, a set of braking devices which are simple, practical and reliable are added, so deceleration and parking of vehicle are convenient. A wheel driving device is especially designed, and a set of reverse mechanisms which are simple and practical are designed according to the travel theory of the vehicle and combining the particular working environment of mowers.
Description
The utility model relates to a kind of mowing machinery, is in particular a kind of transmission of power of self-propelled mower and the self-propelled mower driving rear axle of Control System Design.
At present, the design ubiquity of self-propelled mower the single or shortcoming such as operation inconvenience etc. of performance, and the design defect of this and its transmission system and control system is related.
The purpose of the utility model design provides the driving rear axle of using on the good again self-propelled mower of a kind of simple, practicality and performance.
The self-propelled mower back axle of the utility model design comprises two semiaxis that are located between two rear wheels, is provided with differential mechanism between two semiaxis, and differential mechanism upwards is provided with changement and brake device successively thus;
Wherein, described differential mechanism comprises a pair of axle shaft gear, and the star-wheel assembly between the axle shaft gear also is provided with a larger-diameter gear on the axle shaft gear, this gear and main drive gear engagement;
Described changement comprises the main drive gear of a belt length axial cone tooth, on this main drive gear axle, be provided with three intermeshed gear, idle pulley and power gear from bottom to top successively, on the main drive gear axle at corresponding idle pulley place, be provided with clutch collar, on corresponding power gear, also have sprocket wheel;
The last top of described main drive gear axle is connected with brake disc, and described part brake disc is sandwiched between two friction plates, and described friction plate is fixed on the brake holder, is provided with ejector pin below friction plate, has plate at ejector pin.
Wherein, described semiaxis and wheel junction also are provided with flat key.
Described brake holder is fixed on the axle housing.
The design feature of the self-propelled mower back axle of the utility model design is:
1, the power that is imported into by sprocket wheel is before the input main drive gear, earlier through a cover commutation device, with advancing and retreat of decision vehicle, be that the power gear pine that sprocket wheel drives is enclosed within on the axle of master bevel gear, often mesh with idle pulley simultaneously that the inner spline of clutch collar links to each other with the master bevel gear axle; When clutch collar engaged with power gear, main drive gear and power gear are locked was one, rotation in the same way together, and powered vehicle is advanced; Otherwise when clutch collar and gear engagement, main drive gear and gear are locked is one, and power is passed to gear through idle pulley, makes main drive gear and power gear reverse rotation, and powered vehicle retreats; When clutch collar during in the centre position, driving force is cut off, vehicle lay-off.
2, brake holder is fixed on the axle housing, and manipulation device is housed on it, and the brake disc of rotation is fixed on the axle of main drive gear, when plate when pulled, ejector pin promotes friction plate, makes it to clamp brake disc, with abrupt deceleration vehicle.
3, differential mechanism culminant star wheel assembly and axle shaft gear can be dressed up one easily, and when left and right wheels had speed discrepancy, axle shaft gear can freely rotate in than gear wheel in large diameter.
4, consider particular job environment of mower, semiaxis is designed to bearing type, in the hope of compact conformation; With the left half axle is example, and in axle housing, the outer end is fixed together with flat key and wheel with bearing fixing, and the inner is with the spline axle shaft gear of ining succession, and is supporting than gear wheel in large diameter.
The self-propelled mower back axle of the utility model design has increased the brake device of the simple and practical reliable operation again of a cover than present like product excellent performance, with the deceleration that makes things convenient for vehicle with park; Also designed wheel driver especially,,, designed simple and practical, the well behaved transmission mechanism of a cover in conjunction with particular job environment of mower according to the running car theory.
Further describe the utility model below in conjunction with drawings and Examples
The surface structure schematic diagram of the self-propelled mower back axle that accompanying drawing 1 designs for the utility model;
