Abstract
The invention discloses a motor tricycle for realizing parking braking by a driving shaft. A brake is arranged between a reducer case of the motor tricycle and the driving shaft; a brake hub of the brake is fixedly connected to a rotating body; the rotating body is connected with the driving shaft through a universal joint coupling and is fixedly connected with the circumferential direction of an extending end of an angle tooth input shaft; a base plate of the brake is fixedly connected onto the reducer case; a brake shoe arranged on the base plate is positioned in a brake hub cavity; and a brake adjusting arm of the brake is connected with a parking braking operation lever beside a driver seat of the motor tricycle through a control cable. During parking, the driving shaft is braked by the brake, so that the sliding after parking is prevented; and in addition, the phenomena that the wear of a brake pad of a foot brake of the motor tricycle is serious and the driving brake effect is influenced due to the fact that a driver forgets to completely release the parking braking during driving can be avoided.
Description
Technical field
The present invention relates to the motor-tricycle field, particularly a kind of motor-tricycle of transmission shaft braking during standstill.
Background technology
At present; The braking during standstill of motor-tricycle; Be after motor-tricycle stops, handle the parking brake joystick, in the drg of trailing wheel motor cycle rear wheel is carried out braking during standstill through control setting; Prevent that the motor-tricycle back of stopping on the road surface, slope from slipping car and make of moving down, with the safety after the Parking of assurance motor-tricycle in external force automatically.But, because the braking during standstill and the travelling brake of existing motor-tricycle is the shared drg that is arranged at trailing wheel, usually driver's braking during standstill can appear and after; When driving again, forget and remove braking during standstill fully; Thereby cause motor-tricycle under brake facing is in Frotteurism, to go, cause the brake facing serious wear, influence the service brake effect; The driving safety of motor-tricycle is reduced, bury major traffic accidents hidden danger.
Summary of the invention
The objective of the invention is deficiency to the prior art existence; A kind of motor-tricycle of transmission shaft braking during standstill is provided; It passes through between the reducer shell of motor-tricycle back axle and transmission shaft, to install a drg, and the braking adjusting arm of the drg parking brake lever other with being located at the motor-tricycle operator's saddle is connected through the control drag-line, when Parking, through this drg transmission shaft braked; Slippery after preventing to stop; And forget in the time of can preventing to drive and remove braking during standstill fully, cause the brake facing serious wear of motor-tricycle service brake, influence the service brake effect.
The objective of the invention is to realize like this: motor-tricycle includes the back axle assembly to the trailing wheel transferring power; And the transmission shaft that engine power is passed to back axle assembly; The angle tooth input shaft of back axle assembly upper reducer is supported in reducer shell rotationally and cooperates with the end-cover axle bearing of reducer shell through bearing; One end of angle tooth input shaft stretches out the end-cover axle bearing outward; One drg is installed between said reducer shell and the transmission shaft, and the braking hub of said drg is fixedly connected on the swivel, and this swivel links to each other with transmission shaft through gimbal coupling; Swivel is captiveed joint with the overhanging end of angle tooth input shaft is circumferential; The base plate of drg is fixedly connected on the reducer shell, and the brake shoe brake cheek of installing on the base plate is positioned at braking hub chamber, and the braking adjusting arm of the drg parking brake lever other with being located at the motor-tricycle operator's saddle is connected through the control drag-line.
The overhanging end of said angle tooth input shaft is connected through spline fitted with swivel, and the axle head of angle tooth input shaft is located with nut.
The overhanging end and the swivel of said angle tooth input shaft are connected through singly-bound, and the axle head of angle tooth input shaft is located with nut.
Said swivel is captiveed joint with gimbal coupling with the braking hub through a terminal pad.
Said terminal pad is provided with center resigning hole and a plurality of mounting hole, is respectively equipped with the assembling and positioning seam on the end face at the axial two ends of terminal pad.
The base plate of said drg is connected on the end-cover axle bearing through bolt.
The base plate of said drg is provided with the fixed support of control drag-line.
Owing to adopted such scheme, made motor-tricycle of the present invention have following beneficial effect;
1. a drg is installed between the reducer shell of back axle assembly and transmission shaft; The braking hub of said drg is fixedly connected on the swivel; This swivel links to each other with transmission shaft through gimbal coupling; Swivel is captiveed joint with the overhanging end of angle tooth input shaft is circumferential; The base plate of drg is fixedly connected on the reducer shell, and the brake shoe brake cheek of installing on the base plate is positioned at braking hub chamber, and the braking adjusting arm of the drg parking brake lever other with being located at the motor-tricycle operator's saddle is connected through the control drag-line.When motor-tricycle stops to go when needing Parking after flame-out, form the drag state through handling parking brake lever by drg, transmission shaft can not be rotated, control thus by the transmission shaft wheel driven and can not rotate, realize braking during standstill.And because motor-tricycle of the present invention is to realize braking during standstill through the reducer shell and the drg between the transmission shaft that are installed in back axle assembly; The drg of braking during standstill with travelling brake separated; Solved the drawback that the shared drg of existing motor-tricycle braking during standstill and travelling brake exists; Can avoid being installed in the severe wear that the running brake of trailing wheel causes because of misoperation; The braking effect of service brake is guaranteed, and traveling security is improved, and reduces the generation of traffic accident.
2. said swivel is captiveed joint with gimbal coupling with the braking hub through a terminal pad.Adopt terminal pad to connect swivel, braking hub, gimbal coupling, can make the assembling between swivel, braking hub, the gimbal coupling easy to connect easily.During assembling; With the angle tooth input shaft mount of swivel and retarder good after; Again swivel and terminal pad are passed through bolted connection with the braking hub, just gimbal coupling and terminal pad are fixed through bolted connection then, can guarantee that like this convenient of nut of angle tooth input shaft and swivel shaft alignment installed; Also make simultaneously the moulding of swivel be able to simplify, reduce cost of manufacture.
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
