Abstract
The utility model discloses an axial transmission device for a beach vehicle. The axial transmission device comprises a front gearbox, an output axis of a transmission box, a spline axis, a sliding sleeve and a rear ear box. The front gearbox is provided with a bevel drive gear, a driven spur gear, a driven counter gear and a shift fork mechanism. The shift fork mechanism comprises a shift fork lever, a reverse gear, a shift fork and an adjusting bolt. The rear gearbox is provided with a drive arch and bevel gear and a driven arch and bevel gear, which are of different velocities. The driven arch and bevel gear fixed at a rear axle via a fixing spline. In addition, during an axial transmission, the sliding sleeve is used to replace a universal coupler in an elastic coupler or a double-universal coupler transmission. The front gearbox of the utility model replaces a drive chain wheel of a chain-transmission beach vehicle. Moreover, the reverse gear is provided to realize a function of vehicle backing. In addition, the rear gearbox is designed into the arch and bevel gears of different ratios, which meets the requirement of a high speed or a low speed for the beach vehicle.
Description
Technical field the utility model relates to a kind of transmission device of self-propelled vehicle, particularly a kind of shaft drive of beach buggy.
The common ground of the shaft drive of the shaft drive of the existing beach buggy of background technology and two-wheeled and motor-tricycle is that they mainly are made up of front gear box, rear gear box and three parts of chain stay.But in these three parts, some differences are arranged respectively again, as no reverse gear function in the front gear box of the shaft drive of existing two-wheeled motor vehicle, transmission between the front and rear teeth roller box is general only carries out transmitting movement by a universal coupling, compensate when simultaneously forward and backward transmission shaft position being changed, but this project organization, require the chain stay center of oscillation to want strict and overlap, so both increased the requirement of accuracy of manufacture, reduced mechanical in-use performance again with the center of oscillation of universal-joint.And the employing of the shaft drive of existing motor-tricycle adds that an elastic coupling remedies the deficiency in the above-mentioned technology, but the volume of elastic coupling is bigger, and this just certainly will increase manufacturing cost again.And the sprocket transmission device of existing beach buggy exists the inherent defect of the sprocket transmission device of two-wheeled motor vehicle, thereby the mechanical wear that is its open type driving device causes its maintenance capacity also bigger greatly, and do not have car-backing function in its driving device, can not satisfy the operating needs of height, middle-grade beach buggy driving device.
The summary of the invention the technical problems to be solved in the utility model is the shortcoming that overcomes prior art, provides a kind of and has energy-efficiently, improves mechanical life and makes things convenient for the shaft drive of beach buggy of the comprehensive benefit of driver behavior.
The shaft drive of the utility model beach buggy, be achieved by following technical proposals, a kind of shaft drive of beach buggy, the output shaft, castellated shaft, universal coupling, tween drive shaft, slippage cover and the rear gear box that comprise front gear box, change speed gear box, be provided with driving bevel gear in the described front gear box, just change ring gear, counter-rotating ring gear and shifting fork mechanism, wherein shifting fork mechanism includes shifting fork bar, reverse gearwheel, shift fork and set screw; Be provided with the active arc finishing bevel gear cuter and the passive arc finishing bevel gear cuter of different speed ratios in the described rear gear box, wherein passive arc finishing bevel gear cuter is captiveed joint by spline with hind axle, in addition an elastic coupling in the employing slippage cover replacement three-wheel vehicle shaft drive or a universal coupling in the double universal coupling transmission in shaft drive.
Because front gear box of the present utility model has replaced the drive sprocket of chain-driving beach buggy, has increased reverse gearwheel, thereby has realized car-backing function; Rear gear box is designed to the arc finishing bevel gear cuter of different speed ratios and is connected the front and rear teeth roller box by universal coupling with the slippage cover carry out transmission in addition, has therefore satisfied the requirement of the high low velocity of beach buggy again.
Description of drawings is described in further detail the utility model below in conjunction with accompanying drawing:
Fig. 1 is an overall structure scheme drawing of the present utility model.
Fig. 2 is the A-A cross-sectional view of front gear box among Fig. 1.
Fig. 3 is the structural representation of front gear box rotating gear shift mechanism among Fig. 2.
The specific embodiment as Figure 1-3, the utility model comprises output shaft 2, castellated shaft 3, universal coupling 4, tween drive shaft 5, slippage cover 6 and the rear gear box 7 of front gear box 1, change speed gear box, be provided with driving bevel gear 9 in the described front gear box 1, just change ring gear 10, counter-rotating ring gear 11 and shifting fork mechanism, wherein shifting fork mechanism includes shifting fork bar 12, reverse gear tooth 13, shift fork 14 and set screw 15; Be provided with the active arc finishing bevel gear cuter 8 and the passive arc finishing bevel gear cuter 16 of different speed ratios in the described rear gear box 7, wherein passive arc finishing bevel gear cuter 16 and hind axle 17 are captiveed joint by spline, adopt slippage cover 6 to replace a elastic coupling in the three-wheel vehicle shaft drives or a universal coupling 4 in the double universal coupling transmission in addition in shaft drive.
Principle of work of the present utility model is: as shown in Figure 1, the shaft drive of the utility model beach buggy is that the driving bevel gear 9 with the output shaft 2 of driving engine by change speed gear box and front gear box 1 is connected with spline, by after just changeing ring gear 10 or counter-rotating ring gear 11 and reverse gear tooth 13 being meshed, the gyroscopic movement of output reaches castellated shaft 3, and then after universal coupling 4, tween drive shaft 5 and slippage cover 6 reach tooth axle box 7.As shown in Figure 2, the shift fork 14 of the utility model front gear box 1 is fixed on the shifting fork bar 12, and the position of setting nut 15 on shifting fork bar 12 is adjustable, so that control shift fork 12 is correctly located.When the dog of shift fork 14 when just changeing in the ring gear 10 the corresponding grooves engagement, castellated shaft 3 is for just changeing; When corresponding grooves meshed in the other end dog of shift fork 14 and the ring gear 11 that reverses, castellated shaft 3 was counter-rotating.As shown in Figure 3, the base plate 18 of the rotating gear shift mechanism of front gear box is fixed on the casing of front gear box 1, be welded in be equipped with in the eccentric disk 20 on the sleeve 19 pin 24 and two connecting rod pieces 22 and 23 and pin 21 constitute a connecting rod operating system, when manipulating handgrip 25, can make fixing angle of sleeve 19 revolutions, and drive set screw 15 by connecting rod operating system and do the action of advancing or retreating, thereby finish the operation of rotating shift, and the location of shift position is realized by extension spring.
