Background technique
Full-region vehicle (All Terrain Vehicle) is called for short ATV, is commonly called as beach buggy, can be applicable to various places such as comprising sandy beach, riverbed, mire, the environment landform of challenge all obstacles.
Full-region vehicle does not in the past have reverse gear, and is very inconvenient during actual the use, occurring under the situation that roadblock in time do not avoid, and the driver can only get off and carry out getting around, and just is difficult to get rid of poverty when car is absorbed in the sand pit.Therefore, the various full-region vehicles that have reverse gear mechanism have appearred on the market in succession, as Chinese model utility disclosed " beach buggy reverse gear changement " (CN2563095Y), it comprises the motor input shaft, output shaft and cabinet, changement is located in the cabinet, changement is mainly by driving gear, internal gear, planetary gear set, shift fork push rod; parts such as rocking arm are formed; the output shaft spline connects driving gear; driving gear and internal gear are rotationally connected by bearing and back-up ring; internal gear is fixedlyed connected with sprocket wheel; planetary pinion set square triangle and output shaft joint sleeve are rotationally connected; planetary gear set is fixed on the planetary pinion set square triangle, and locating stud is fixedlyed connected with the shift fork push rod, the shift fork push rod moves in pushing rod sleeve; shift fork push rod and planetary pinion set square triangle flexibly connect, and rocking arm is fixed on push rod control and puts.Its working principle is, engine output shaft is passed to driving gear with power, drives planetary pinion set square triangle assembly and rotates, and at this moment, planetary pinion and internal gear rotate synchronously, and last power is by the output of the sprocket wheel on the internal gear, and driving gear turns to consistent with internal gear; When the driver spurs operating handle, operating handle pulling push rod control cover rocking arm revolves and turn 90 degrees, driving push rod control cover rotates, move after making planetary pinion set square triangle shift fork push rod, planetary pinion set square triangle assembly is thrown off driving gear and the engagement of braking flange, this moment, planetary pinion set square triangle assembly did not rotate, and the switched in opposite of driving gear and internal gear reaches the purpose of reverse gear.
The changement of said structure, though realized the reversing problem of beach buggy, the structure of cooperation transmission between the gear and integral body is comparatively complicated, thereby causes the vehicle performance reliability decrease, processing cost is also higher relatively.
Summary of the invention
The utility model purpose provides a kind of simple in structure, and is functional, makes full-region vehicle can be suitable for the reversing gearshift that different occasions are used.
For achieving the above object, the technical solution adopted in the utility model is: a kind of backing device of full-region vehicle, mainly constitute by housing and the output shaft that is rotationally connected with housing, input shaft, be provided with gearshift mechanism in the housing, described gearshift mechanism comprises bevel gear set, passive tooth wheels and fork shift mechanism; Wherein bevel gear set is made up of second bevel gear and the third hand tap gear that are fixedly connected on first bevel gear on the input shaft, are connected with a joggle with first bevel gear respectively, direction is oppositely arranged; Described passive tooth wheels comprise first driven gear that is connected with a joggle with second bevel gear and second driven gear that is connected with the third hand tap gear engagement, and both distinguish sliding sleeve on output shaft; Described fork shift mechanism by be positioned at combination gear between first, second driven gear, be sheathed on clutch ring on the combination gear and driving lever, shift fork forms, wherein the combination gear inner chamber is connected with spline with output shaft, combination gear periphery and first, second driven gear are equipped with the spline that cooperates with the clutch ring with the adjacent portions of combination gear, and described clutch ring is provided with the groove that cooperates with shift fork.
In the technique scheme, the outside of described first driven gear and second driven gear, nearly combination gear end is respectively equipped with spline identical with combination gear and that communicate, and spline one end is provided with limited ring, and limited ring is to the distance on the driven gear top width less than the clutch ring.
In the technique scheme, an end of described driving lever is provided with 3 locating slots, is provided with fastener corresponding to the cabinet above the locating slot; Described fastener is a resilient member.
In the technique scheme, described driving lever is connected by the outer handle of driving mechanism and cabinet; Described input shaft, output shaft are rotationally connected by bearing unit and housing formation.
The utility model working principle is: input shaft drives first bevel gear and rotates, driving second, third bevel gear by first bevel gear rotates, because second, third bevel gear is the bevel gear that a pair of number of teeth is identical, direction is relative, by the bevel gear working principle as can be known, the rotating speed of second, third bevel gear is identical, and direction is opposite; And second, third bevel gear drives first driven gear and second driven gear rotates, and both directions are opposite equally; Mobile drive shift fork by driving lever moves, thereby also having driven the clutch ring moves in the spline that combination gear and driven gear are combined into, the output shaft of fixedlying connected with combination gear with the rotation drive of driven gear is pressed the sense of rotation of driven gear and is rotated, and realizes advancing and retreating of vehicle.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1. because the utility model utilizes the work characteristics of bevel gear, drive a pair of driven gear with equal rotating speed, different direction rotations, thus drive the forward or reverse of output shaft, realize advancing and falling back of vehicle; With the motion of two pairs of comparatively common Gear combination realization vehicles, simple in structure, reliable performance is easy to realize that processing cost is lower;
The utility model position by the clutch ring on output shaft make combination gear respectively with different driven gear combinations, thereby change turning to of output shaft, it is simple in structure, and is easy to operate.
