Abstract
The utility model discloses a novel rear independent suspension transmission box for chain drive of a dune buggy. The transmission box mainly comprises a rear drive system and a rear brake system, which are formed by major parts including a rear transmission box body, a cage half shaft, a support and a transmission piece; and auxiliary parts including a rear chain wheel, a chain, a disc brake and a rear disc brake. The transmission box can transfer the power and moment output from the engine to wheels, thereby ensuring the normal operation of the dune buggy; and moreover, the transmission box is combined with rear left/right upper/lower swinging arms and rear damper to form a suspension system which transfers the force and moment acting between the wheel and the vehicle frame. Additionally, the transmission box can weaken the impact force on the vehicle frame or body when driving on the rough road and attenuate the vibration caused thereby, thereby ensuring the dune buggy to drive smoothly. The whole suspension system can allow the left and the right wheels to jump independently without mutual interference and reduce the inclination and vibration of the vehicle body, thereby improving the comfort and driving stability of the dune buggy.
Description
Technical field
The utility model relates to a kind of beach buggy driving device, relates to a kind of beach buggy chain-driving independent rear suspension transmission gearbox particularly.
Background technology
Beach buggy is emerging a kind of special vehicle, is a kind of full landform four wheeler.Especially the car that the chain-drive kinesthesia is very strong is liked by the customer more and more, the car that chain-drive kinesthesia in the market is very strong hangs thereafter and mostly adopts beam rear axle, adopt central authorities' single back shock-damping structure, problem of the car ubiquity of this structure is exactly because back axle and chain stay fuse, by chain stay hole bolt it is connected to ground again, the integral body that back axle and chain stay are formed is rotated around chain stay hole bolt, and can not eliminate the hollow uneven vibrations that produce in top, road surface, so traveling comfort and cruising characteristic are poor, man-machine performance is bad, in addition because the installation of sprocket wheel and guard shield thereof, the ground Clearance of this class car is very little, crossing ability is poor, has limited the performance of vehicle performance so greatly.
The utility model content
Deficiency at above beam rear axle, the utility model provides a kind of new beach buggy chain-driving independent rear suspension transmission gearbox, its with the back damping, about go up the independent rear suspension system that lower shake-changing arm and vehicle frame etc. constitute beach buggies, can solve Windsor, traveling comfort and reach the problem that crossing ability improves well.
For achieving the above object, the utility model adopts following technical scheme: a kind of beach buggy chain-driving independent rear suspension transmission gearbox, comprise that back sprocket wheel, rear axle reach and being used for and rear wheel bonded assembly transmission body that rear axle connects, described rear axle is made of the ball cage semiaxis of two symmetries, each ball cage semiaxis each by with described transmission body spline bonded assembly ectosphere cage, be installed on the internal spherical cage of back sprocket wheel mount pad and constitute with interior ectosphere cage spline bonded assembly semiaxis; Described back sprocket wheel mount pad extends into horn-like to side foreign side, described back sprocket wheel is installed on its exit skirt edge, the outside bearing set of this back sprocket wheel mount pad and by bearing installation in the transmission gearbox casing; Also be set with the butterfly dish mount pad of stopping on the sprocket wheel mount pad of back, this butterfly dish mount pad of stopping extends into horn-likely to side foreign side, and the butterfly dish of stopping is installed on its exit skirt edge; On described transmission body excircle, bearing is housed, the supporter that is used to connect the independent rear suspension system by bearing installation in transmission body.
Because beach buggy rear axle of the present utility model adopts two ball cage semiaxis, the independent rear suspension system is connected in ectosphere cage and transmission gearbox casing by supporter and vehicle frame, left and right wheels is beated separately in motion process, irrelevant mutually, can reduce the inclination and the vibrations of vehicle body, its ride comfort, Windsor, through performance also obtain bigger raising.Internal spherical cage install with back sprocket wheel mount pad is connected, butterfly stop the dish mount pad with after the installation of sprocket wheel mount pad be connected the power that then both can guarantee driving engine and reach braking trailing wheel to the rear drive sprocket transmission, can guarantee that again each wheel is unaffected with beating of landform.
