Abstract
The utility model provides a reversing auxiliary shaft assembly of a motorcycle, comprising an auxiliary shaft (1). The auxiliary shaft (1) is provided with a one-gear driven gear (2), a two-gear driven gear (3), a three-gear driven gear (4) and a reverse-gear driven gear (5). Wherein, the one-gear driven gear (2) and the two-gear driven gear (3) are movably sheathed on the auxiliary shaft (1), the three-gear driven gear (4) is arranged on the auxiliary shaft (1) by a key and a key way which conduct clearance fit and is arranged between the one-gear driven gear (2) and the two-gear driven gear (3); the reverse-gear driven gear (5) and the auxiliary shaft (1) conduct splined connection, the auxiliary shaft (1) between the two-gear driven gear (3) and the reverse-ear driven gear (5) is provided with a bush (6), and one end of the bush (6) is contacted with the end face of the reverse-ear driven gear (5). The reversing auxiliary shaft assembly of a motorcycle solves the problem that the reverse-gear driven gear and the auxiliary shaft are easy to slip, and the reverse gear for an engine is safer.
Description
One, technical field:
The utility model belongs to the motor cycle engine technical field, specifically, is a kind of motor bike reverse gear countershaft combination.
Two, background technology:
At present, the combination of motor bike reverse gear countershaft mainly is made of countershaft, first speed driven gear, second gear driven gear, third gear driven gear and reverse gear driven gear, this countershaft makes up existing D Drive function, the reverse gear function is arranged again, wherein adopt interference fit to be connected between reverse gear driven gear and the countershaft, the reverse gear driven gear is solidly set on the countershaft, during use, by rotating, realize reverse gear with the moving countershaft opposite sense of reverse gear driven gear ingear gap bridge cingulum.But if magnitude of interference deficiency between reverse gear driven gear and the countershaft makes to be connected firmly inadequately between reverse gear driven gear and the countershaft, or the external force moment of torsion is excessive during reverse gear, all can make the phenomenon that occurs skidding between reverse gear driven gear and the countershaft, causes reverse gear to lose efficacy
Three, utility model content:
The purpose of this utility model provides the combination of a kind of motor bike reverse gear countershaft, solves in traditional motor bike reverse gear countershaft combination to skid easily between the reverse gear driven gear and countershaft, thus the problem that causes reverse gear to lose efficacy.
The technical solution of the utility model is: it comprises that countershaft, countershaft are provided with first speed driven gear, second gear driven gear, third gear driven gear and reverse gear driven gear, wherein first speed driven gear and second gear driven gear kink are on countershaft, the third gear driven gear is installed on the countershaft by the key and the keyway of free-running fit, and between first speed driven gear and second gear driven gear, be connected for spline between described reverse gear driven gear and the countershaft; Countershaft between second gear driven gear and the reverse gear driven gear is provided with lining, and an end of lining contacts with the end face of reverse gear driven gear.
In the utility model between reverse gear driven gear and the countershaft for spline is connected, promptly cooresponding spline flush fit on the female splines of reverse gear driven gear and the countershaft makes being connected firmly between reverse gear driven gear and the countershaft, the moment of torsion transmission more reliable between them; On the countershaft between second gear driven gear and the reverse gear driven gear, lining is set,, therefore, when the processing countershaft, just can reprocess limited step, simplified production technology, reduced cost so that the reverse gear driven gear is carried out axial limiting.
The utility model has the advantages that: solved easy problem of slip between reverse gear driven gear and the countershaft, made driving engine reverse gear safety and reliability, and simplified the production technology of countershaft, reduced cost.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the axial scheme drawing of reverse gear driven gear 5 among Fig. 1.
Five, the specific embodiment:
As shown in Figure 1 and Figure 2: the utility model is made up of countershaft 1, first speed driven gear 2, second gear driven gear 3, third gear driven gear 4, reverse gear driven gear 5 and lining 6, wherein first speed driven gear 2 and second gear driven gear 3 kinks are on countershaft 1, third gear driven gear 4 is installed on the countershaft 1 by the key and the keyway of free-running fit, and between first speed driven gear 2 and second gear driven gear 3, be connected for spline between described reverse gear driven gear 5 and the countershaft 1; Countershaft 1 between second gear driven gear 3 and the reverse gear driven gear 5 is provided with lining 6, and an end of lining 6 contacts with the end face of reverse gear driven gear 5, so that countershaft 1 is carried out axial limiting.
In addition, one section that 5～7mm length is arranged between the spline tooth of reverse gear driven gear 5 and countershaft 1 in the axial direction is that the slight interference amount cooperates, and is convenient to the location during assembling, makes things convenient for the installation of reverse gear driven gear 5 on countershaft 1.
When driving engine is in the reverse gear position, power is given engine spindle through clutch transmits, reverse driving gear on main shaft is delivered to the gap bridge tooth again, gap bridge tooth and 5 engagements of reverse gear driven gear, thereby power is delivered on the countershaft 1 through reverse gear driven gear 5, realize reverse gear, owing to be connected for spline between reverse gear driven gear 5 and the countershaft 1, even therefore run into the excessive situation of moment of face, the phenomenon that also can not occur skidding between reverse gear driven gear 5 and the countershaft 1, thus the reliability of whole driving engine reverse gear function improved.
Claims (2)
1, a kind of motor bike reverse gear countershaft combination, comprise that countershaft (1), countershaft (1) are provided with first speed driven gear (2), second gear driven gear (3), third gear driven gear (4) and reverse gear driven gear (5), wherein first speed driven gear (2) and second gear driven gear (3) kink are on countershaft (1), third gear driven gear (4) is installed on the countershaft (1) by the key and the keyway of free-running fit, and be positioned between first speed driven gear (2) and the second gear driven gear (3), it is characterized in that: be connected for spline between A, described reverse gear driven gear (5) and the countershaft (1); Countershaft (1) between B, second gear driven gear (3) and the reverse gear driven gear (5) is provided with lining (6), and an end of lining (6) contacts with the end face of reverse gear driven gear (5).
2, motor bike reverse gear countershaft combination according to claim 1 is characterized in that: one section that 5～7mm length is arranged between the spline tooth of described reverse gear driven gear (5) and countershaft (1) in the axial direction is that the slight interference amount cooperates.
