Abstract
The utility model belongs to the transmission technology for positive motor tricycle, and puts forward a gear tumbler for reverse and advance gear. The gear tumbler for reverse and advance gear is provided with: a driving bevel gear (6) connected with an engine output shaft (21); two driven bevel gears (5) meshing with the driving bevel gear (6), wherein, two driven bevel gears (5) are symmetrical arrangement and opposite in rotating direction; a meshing sleeve (12) which moves left and right along with a shifting fork (2) and meshes with two driven bevel gears, wherein, the meshing sleeve (12) is covered on a gear tumbler output shaft (13) and can move along a key groove on the output shaft (13), and two ends of the meshing sleeve (12) are respectively provided with teeth for meshing with upper tooth holes of the driven bevel gears (5); a coupling joint (14) used to be connected with a rear axle assembly (26) through universal joints (23), (25) and a transmission shaft (24), and the gear tumbler output shaft (13) is in key connection with the coupling joint (14). The utility model is reasonable in design and simple in structure, and is characterized in convenient operation and good reliability.
Description
Affiliated technical field
The utility model belongs to the motor tricycle drive technology, mainly proposes a kind of along a shelves gear tumbler.
Background technique
Adopt chain-driven and general nothing that reverse gear mechanism is set at present between its motor of motor tricycle that uses and the back axle; The reverse gear mechanism that has proposed also is to utilize increase by one cover chain drive to realize that motor tricycle in use owing to there is not reverse gear mechanism, under steam, need be got off when needing the short distance reversion, and car is to rollback, very inconvenient.And the reverse gear structure of the chain structure that proposes.Owing to use link chain mechanism to realize sternway, project organization comparatively complexity and operability is bad.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of falling along a shelves gear tumbler, is used for transmitting torque between motorcycle engine and the back axle, realizes positive tricycle forward gears and the conversion that retreats shelves, and has easy to operate and characteristics good reliability.
The utility model is finished the technological scheme that its invention task taked: be provided with the drive bevel gear that is connected with engine output shaft, be provided with two with drive bevel gear engagement by dynamic bevel gear, two are symmetrical arranged and direction of rotation by dynamic bevel gear, setting is with shift fork move left and right and two engagement covers that meshed by dynamic bevel gear, engagement is enclosed within on the commutator output shaft and can moves along the keyway on the output shaft, engagement cover two ends, the left and right sides have in order to the teeth that meshed by the perforation on the dynamic bevel gear; Be provided with in order to by two shaft couplings that universal joint and drive shaft connects with rear axle assy, and with commutator output shaft and shaft coupling binding.
Shift fork is moved to the left under the operating handle effect thus, and drive the engagement cover and be moved to the left along the output shaft spline, engagement cover teeth of left end and being meshed of left end by the dynamic bevel gear perforation, thus just drive being rotated synchronously in the same way of output shaft and this end by dynamic bevel gear.Operating handle makes shift fork move to right, and the engagement cover is moved to right, and the teeth of its right-hand member and right-hand member are made engagement cover, output shaft be rotated synchronously in the same way by dynamic bevel gear with this end by the engagement of the perforation of dynamic bevel gear.Because two by the dynamic bevel gear direction of rotation, thereby realized that the sense of rotation of commutator output shaft changes.The output shaft along the shelves gear tumbler connects with rear axle assy by two universal joint and drive shafts, thereby realizes the transmission of motor to back axle.
The utility model is reasonable in design, simple in structure, has easy to operate and characteristics good reliability.
Description of drawings
Accompanying drawing 1 is the utility model embodiment 1 structural representation.
Accompanying drawing 2 is the side sectional view of Fig. 1.
Accompanying drawing 3 is the driving mechanism schematic representation of motor tricycle.
Among the figure, 1-operating rod bearing, 2-shift fork, 3-declutch shift shaft, 4-housing, 5-by dynamic bevel gear, 6-drive bevel gear, 7-mounting hole, 8-operating handle, 9-hinging shaft, 10-locking steel ball, 11-locking spring, 12-engagement cover, 13-output shaft, 14-shaft coupling, 15-key, 16-bearing cap, 21-engine output shaft, 22-fall, 23,25-universal joint along shelves gear tumblers, 24-transmission shaft, 25-universal joint, 26-rear axle assy.
Embodiment
The embodiment who provides is in conjunction with the accompanying drawings further specified its structure:
Shown in accompanying drawing 1,2, fall and to be provided with drive bevel gear 6 along a shelves gear tumbler, it links by spline and engine output shaft 21, and is provided with two by dynamic bevel gear 5, they and drive bevel gear mesh but two by the dynamic bevel gear direction of rotation.The operating handle 8 that drives shift fork 2 move left and right is set, and it is hinged on the operating rod bearing 1 by hinging shaft 9, and the lower end of operating handle 8 is positioned at the hole of shift fork 2 upper ends, and operating handle presses down thus, and the one end i.e. action to the right, drives shift fork 2 and moves to right thereupon.Shift fork 2 middle parts have axis hole and pass a stationary axle along axis hole is declutch shift shaft 3, and the two ends of declutch shift shaft are fixed on the housing 4, and main effect is to make shift fork 2 along the declutch shift shaft move left and right.The lower end fork arm of shift fork 2 is stuck on the circular groove of engagement cover 12, stirs engagement cover 12 move left and right thereupon.Engagement cover 12 be enclosed within on the commutator output shaft 13 and can along the spline that sets on the output shaft 13 axially (about) move, engagement cover two ends, 12 left and right sides are teeth; Teeth and two are joined by the kiss of the perforation on the dynamic bevel gear 5.Thus, operating handle 8 actions are moved shift fork 2, engagement cover 12 moves thereupon, make the teeth of an end and being meshed of this end by dynamic bevel gear, commutator output shaft 13 and this end are rotated in the same way synchronously by dynamic bevel gear, locking spring 11 withstands in the arc-shaped slot that steel ball 10 just in time is stuck in declutch shift shaft 3, thereby guarantees not out of supplyly, and transmission is reliable and stable.Commutator output shaft 13 connects by key 15 with shaft coupling 14, and connects with universal joint 22 by shaft coupling 14, and the other end of universal joint 22 connects with transmission shaft 24, connects with motorcycle rear axle assy 26 by universal joint 25.
