When accelerating over again, only refueling is needed. The utility model has the advantages of simple operation, less component abrasion, and the utility model has a stated oil-saving effect.

Description

The active transmission shaft of automobile

One, technical field

The utility model belongs to the mechanical power transmission technical field, is specifically related to a kind of truck drive shaft.

Two, background technique

Existing automotive power transmission system is just finished walking with transmission of power to driving wheel, and when car body energy during greater than take-off output,, the direction of transmission of power can be opposite, produces contrary transmission and change, the car body energy will feed back to motor through power-transmission system, make motor do negative work.Motor then became the air compressor of a station symbol standard and at unreasonable ground consumed energy, therefore, can be referred to as ordinary transmission to the design of existing automobile power transmission system this moment.Because the variation that this transmission design can not produce output power along with the variation of car body potential energy has been wasted the valuable energy, so this is a problem demanding prompt solution.

When automobile has certain speed, have only two kinds of modes of operation selective, a kind of is not pluck shelves to slide, the car body inertia potential energy of this moment is subjected to the influence of engine piston pressurized air resistance, and automobile potential energy is not well discharged; Another kind of operation is exactly to pluck shelves, allows automobile inertial obtain performance, but when quickening again, continue clutch engage a gear program, when revolution is asynchronous, also will bang oily engage a gear.These all are invalid program and loaded down with trivial details operation, so present car transmissions are stepped on the throttle the motor acting exactly when not plucking grade; Lift throttle, motor is exactly a resistance.But can not step on throttle always when driving, all simultaneously gear emptied in the time of also can not lifting throttle at every turn.This step on one lift between, be exactly motor as compressor use during, so present vehicle transmission mechanism, no matter what mode of operation the driver takes, and does not all reach desirable effect.

Three, summary of the invention

The purpose of this utility model provides a kind of active transmission shaft of automobile that is connected in the transmission system, this active axle construction can make automobile when sliding, keep former gear constant, do not increase the Piston Compression resistance of air again, energy reasonable use car body inertia power when quickening again, only needs to refuel to get final product, thereby can bring actual oil-saving effect, and can alleviate driver's labor intensity.The technical solution adopted in the utility model is: the active transmission shaft of automobile comprises main shaft, moving gear and fixed gear are installed on main shaft, and moving gear is that spline combines with main shaft, can move axially on main shaft, fixed gear and main shaft are for being slidingly matched, and right-hand member is connected with main shaft through bearing.Main shaft is a reducing, and the stage casing is a splined shaft, and the splined shaft left end is equipped with spring, and the spring right-hand member is a moving gear, and the right-hand member of moving gear is a fixed gear; The main shaft left end is a power intake, and the fixed gear right-hand member is a clutch end.Moving gear is that ratchet combines with the junction plane of fixed gear.Outside moving gear and fixed gear external tooth cover is arranged, moving gear and fixed gear periphery are spline, can cooperate with the external tooth cover interior spline.

During normal transmission, because the ratchet inclined-plane of fixed gear and moving gear engagement, fixed gear and main shaft rotate synchronously, and when automobile running when certain speed need slide, can receive throttle, keep gear constant, at this moment, because the fixed gear rotating speed is greater than the moving gear rotating speed, moving gear overcomes spring pressure to moving to left and fixed gear separates, the asynchronous rotation with main shaft of fixed gear this moment under the effect on ratchet inclined-plane; When quickening again, reply normal processes again.So that this transmission shaft has is easy and simple to handle, reduce the advantage of component wear, and has certain oil-saving effect.

Four, description of drawings

Accompanying drawing is a structural representation of the present utility model.

Five, embodiment

Main shaft 1 is located at active center transmission shaft, and this axle is a collapsable shaft, and this left side section is a circular shaft, and the stage casing reducing is a splined shaft, and right section also is a circular shaft.In the splined shaft left side spring 3 is housed, the moving gear 4 that combines with main shaft 1 spline is equipped with on spring 3 right sides, on the right section circular shaft fixed gear 6 is housed, and fixed gear 6 is slidingly matched with main shaft 1, and its right-hand member is connected with main shaft 1 by bearing 7, and bearing 7 outer ends are lock nut 8; The junction plane 5 of moving gear 4 and fixed gear 6 is for ratchet combines, and external tooth cover 2 is sleeved on moving gear, fixed gear periphery, is that spline combines with moving gear and fixed gear periphery.

The effect of external tooth cover is: when external tooth cover was in the left side, it only combined with moving gear, and does not connect fixed gear, and when automobile running arrived certain speed, fixed gear can separate with moving gear, obtained the effect of aforesaid fuel-economizing, minimizing component wear.And dial to the right when outside shift fork, when external tooth cover combined with moving gear and fixed gear simultaneously, fixed gear was synchronous with moving gear and main shaft all the time, and this just equals to have cut this device, becomes existing fixed axis transmission form.
