The utility model relates to a motor tricycle reverse gear drive axle, which is provided with a box body, a differential assembly connected with a left semi axle and a right semi axle. The box body is provided with a drive and reverse gear mechanism and a gear-shifting and gear-position maintaining mechanism. The drive and reverse gear mechanism is meshed with the main decelerator driven gear of the differential assembly through the main decelerator drive gear to realize the connection. The drive and reverse gear mechanism is composed of a drive bevel gear shaft, a drive gear bevel wheel, a reverse gear bevel wheel, a reverse gear shaft, and a gear-shifting sleeve. The gear-shifting and gear-position maintaining mechanism is composed of a gear-position maintaining spring, a gear-shifting sleeve piece, a gear-shifting shaft, a gear-shifting drum, and a gear-shifting fork. The drive axle has three functions of driving and reversing gears, deceleration, and the differential speed of a left wheel and a right wheel; the gear-shifting operation is convenient and reasonable, drive and revere gear-shifting is automatic, and can not be out of control during transmission. The utility model is simple in structure, reliable in application, and greatly reduces the manufacture cost.
Description
Technical field
The utility model belongs to the vehicle transmission system technical field, is specifically related to a kind of drive axle with reverse gear function that is used for the shaft type motor-tricycle.
Technical background
The transmission system that generally adopts on the shaft type motor-tricycle has two kinds of structures at present.A kind of is that reverse gear and main reduction gear split, and reverse gear is installed on the engine housing, and main reduction gear is installed in the backteeth bag.Another kind is that reverse gear and main reduction gear are integrated, and all is loaded in the backteeth bag.The former major defect is: the number of parts spiral bevel quantity that particularly manufacturing cost is very high is many, needs the leak free position many.So the manufacturing cost height, leakage of oil easily.The latter is because what adopt is that cylindrical wheel is just being realized. reverse gear function, and come gear shift by stirring gear, so structure is still complicated, manufacturing cost is still higher, and gear shift difficulty relatively, gear impacts seriously during gear shift, and gear shift is made sound.
Summary of the invention
The purpose of this utility model is at existing shaft type motor-tricycle transmission system above shortcomings, design a kind of simple in structure, service-strong just has, the drive axle of reverse gear function, not only make shift control convenient. rationally, and manufacturing cost is obviously reduced.
The technical solution of the utility model is as follows: this reverse gear formula drive axle has casing and places in the casing and be connected differential assembly on the semiaxis of the left and right sides, it is characterized in that also being provided with in the casing positive reverse gear mechanism and gear shift and gear maintaining body.Positive reverse gear mechanism is realized connecting by the main reduction gear driven gear engagement of main reduction gear driving gear and differential assembly; Positive reverse gear mechanism is by the drive bevel gear axle. and finishing bevel gear cuter advances. the reverse gear finishing bevel gear cuter. reverse gear shaft and shift sleeve are formed.The drive bevel gear axle meshes with advance finishing bevel gear cuter and reverse gear finishing bevel gear cuter respectively, reverse gear shaft is slidingly connected by the rectangle female splines on its rectangle male splines and the shift sleeve, be fixedly connected with the rectangle female splines on the main deceleration driving gear, advance finishing bevel gear cuter and the equal sky of reverse gear finishing bevel gear cuter are enclosed within on the reverse gear shaft.Shift sleeve connects the control fork of gear shift and gear maintaining body.
Described gear shift and gear maintaining body keep spring, gear shift external member, shift shaft, gear shift drum and gear shift fork to form by gear, shift shaft and gear shift drum combine as a whole with bolt, have one the right hand helix groove on the gear shift drum of outer post, guide pin one end enters this plug helix, and the other end inserts in the respective aperture of gear shift fork.
The driven gear of described main reduction gear pair and differential gear box Bolt Connection constitute differential assembly jointly with planetary differential bevel gear, compensating-gear shaft and semi-axle bevel gear.The main reduction gear pair is made of driving gear and driven gear engagement, and they are a pair of common displacement cylindrical gear pairs.
Drive axle according to this technical scheme is made just has, reverse gear, deceleration and the left and right differential three big functions of taking turns, and shift control is convenient, reasonable, advance and reverse gear can advance shelves automatically, and trip stop not, simple in structure, use reliably, manufacturing cost obviously reduces.
Description of drawings
