Abstract

The utility model relates to a shaft-drive device with a reverse gear for a motor tricycle, which relates to a gear drive device for the reverse of rotation movement. The reverse device of an existing motor tricycle mainly adopts chain transmission. Few motor tricycles use the spur gear shaft drive of a parallel shaft. The reverse of the motor tricycle with the vertical shaft drive can not be solved. The utility model is characterized in that two driving cone gears (1) which are frequently engaged with a driven cone gear (6) are freely sheathed on a driving spline shaft (2). A control mechanism for manipulating gear change is connected to the driving cone gears on a left (right) edge through a movement connection sleeve (4) of a purpose-made gear change plate (11). Thus, the driven cone gear is driven to rotate clockwise (or counterclockwise) for realizing the advancing or the reversing of the motor tricycle with the vertical shaft drive.

Description

The shaft drive of motor tricycle band reverse gear

The utility model relate to F16H be used to make rotatablely move the commutation gear drive, be a kind of shaft drive of intersecting axle band reverse gear.

The multiple model motor tricycle that known motorcycle gasoline engine output shaft is vertical with direction of traffic adopts chain-driven unit, its sprocket wheel, chain wear fast mostly, and fault is many, and working life is short, maintains very inconveniently, and noise is big; Partly adopt driven off by shaft motor tricycle not have reverse gear mechanism, vehicle can not be moveed backward, and drives very inconvenient; The device of the shaft drive band reverse gear of 750CC motor tricycle, its output shaft of gasoline engine is parallel with direction of traffic, can not satisfy the usage requirement of the output shaft of gasoline engine motorcycle vertical with direction of traffic.

The purpose of this utility model is to overcome the deficiency of above-mentioned motor tricycle driving mechanism, the shaft drive of a kind of output shaft of gasoline engine motor tricycle band reverse gear vertical with direction of traffic is provided, convenient for maintaining and maintenance are satisfied users to motor tricycle rate performance demands.

The purpose of this utility model reaches by following approach: the shaft drive of motor tricycle band reverse gear, relate to and be used to make the gear drive that rotatablely moves and commutate, gear box, driving gear pair, gear shaft, shift control mechanism etc. are arranged, it is characterized in that two active cone gear (1) skies that have mesh splines are enclosed within same initiatively the right and left of splined shaft (2) cylindrical, two coupling sleeve teeth (3) are set on the spline of active splined shaft from two ends, two clutch collars (4) are set on the external splines of coupling sleeve tooth (3) again; The driven bevel gear (6) of band splined shaft and the two initiatively normal engagements of cone gear (1); Clutch collar (4) by shift control mechanism shift fork (5) connect a left side or the right active cone gear (1) so that driven bevel gear (6) clockwise or be rotated counterclockwise, thereby make motor tricycle realize advancing or moveing backward two to motion.The master and slave moving axis of the utility model is reversible to use, promptly when the axle of cone gear (6) connects with output shaft of gasoline engine; Then it does initiatively circle dimension gear use, splined shaft this moment (2) then becomes driven shaft, and its action principle is feasible equally, so the allocation position of the utility model on vehicle can be at the output shaft of gasoline engine place, can be on the motor tricycle back axle, any position also can be situated between.

The utility model can be realized advancing of motor tricycle that output shaft of gasoline engine is vertical with direction of traffic or move backward, and makes things convenient for the vehicle awl to repair and maintain, and be convenient to drive, and applicability is strong, can be used for the motor tricycle of various capacity, has satisfied users' requirement.

Structural design drawing when Fig. 1 is the utility model neutral gear.

Fig. 2 is the utility model shift control principle figure.

Details are as follows in conjunction with the accompanying drawings for the utility model embodiment: active cone gear (1) sky of two band mesh splines is enclosed within initiatively splined shaft (a 2) cylindrical the right and left, and its driven bevel gear (6) with the band splined shaft is often meshed, again two coupling sleeve teeth (3) are sleeved on the spline of active splined shaft (2), and lean against respectively by the spline of active cone gear (1), respectively be set with clutch collar (4) on the external splines of two coupling sleeve teeth (3), two forks of shift fork (5) are inserted a left side respectively, in the circular groove of right two clutch collars (4), shift fork (5) is loaded on declutch shift shaft (9) upward also can be along this axial move left and right, when stirring handle adapter (12) and shift plate (11) and drive shift fork (5) and be moved to the left by being contained in Joystick outside the gear box casing (10), then drive the spline engagement of the active cone gear (1) on clutch collar (4) and the right, the active cone gear (1) on the right is the clutch collar (4) by the right just, coupling sleeve tooth (3) and initiatively splined shaft (2) interlock, and do clockwise (or counterclockwise) rotation to drive driven bevel gear (6) with active splined shaft (2) rotation synchronously, vehicle is advanced (or reversing), and this moment, the active cone gear (1) on the left side was transferred not transferring power in the axle sky; When stirring the move right spline engagement of the clutch collar (4) that then promotes the left side and the active cone gear (1) on the left side of shift fork (5), the active cone gear (1) on the left side just rotates with active splined shaft (2) by the clutch collar (4) and the coupling sleeve tooth (3) on the left side, thereby drive driven bevel gear (6) and do counterclockwise (or clockwise) rotation, can make vehicle backing (or advancing), the clutch collar (4) on this moment the right moved right withdraw from and the right initiatively cone gear (1) spend strong engagement, the active cone gear (1) on the right is then overhead then can not transferring power at active splined shaft (2).The axle head of driven bevel gear (6) is shaped on spline, can be connected into one with the transmission shaft that is connected the backteeth bag (8) by splined cover (7).For making the utility model work gear accurate, during each gear engaged by stopper (13) self-locking, when stopper (13) is positioned at groove (A), be neutral position, this work gear when stopper (13) is positioned at groove (C) or (B) (advance or move backward), its stroke distances is controlled by shift plate (11), the shift plate is shaped on elliptical slot on (11), the pin of shift fork (5) inserts in the elliptical slot of shift plate (11), (a) position in the middle of the pin of shift fork during neutral gear (5) is positioned at, when pulling handle adapter (12) to the right or left and make stopper (13) enter (B) or (C) location groove, the pin of shift fork (5) is shifted to (b) or (c) point along the axial straight line of declutch shift shaft (9), the elliptical slot of shift plate (11) (a ') (aa ' line segment be the poor of oval groove major and minor axis) point should guarantee to satisfy and the stroke of (b) point (or (c) point), i.e. ob=oc=oa ' are put in control (a).

The master and slave moving axis of the utility model is reversible to use, promptly can make driving shaft usefulness with the output shaft of gasoline engine connection with the cone gear (6) of splined shaft, and splined shaft this moment (2) becomes driven shaft, and its action principle is same as described above, and just transmission direction is opposite.
