Abstract

The utility model relates to a gasoline-saving sliding device for a vehicle. The utility model is provided with a main shaft whose front end is provided with a connecting flange. The upper side of the main shaft is assembled with a casing through a front and back bearings, and the upper side of the casing is provided with a position blocking sliding bush. The inner part of the casing is provided with a driven ratchet wheel, a driving ratchet wheel, and a clamping ratchet wheel. The driven ratchet wheel is fixed with the casing. The key of the driving ratchet wheel is matched on the main shaft in a sliding way. The key of the clamping ratchet wheel is matched on the casing in a sliding way and is connected with the position blocking sliding bush. The utility model is arranged between the drive shaft and the differential mechanism of wheels. An electromagnetic valve is used for controlling the clamping ratchet wheel to move forwards and backwards in the casing to realize the locking and the disjunction of the driving ratchet wheel and the driven ratchet wheel. When the vehicle is ensured to run safely, the fuel oil can be saved, and the mechanical wear can be reduced.

Description

The vehicle oil saving skid

The utility model relates to a kind of vehicle oil saving skid.

Common diesel motor car, the speed of engine petrol car are subjected to the engine speed restriction, the rotating speed height of driving engine, the rotating speed of wheel is also high, and when time of engine low speed, wheel will drive engine running under the driving of force of inertia, this moment, driving engine became the resistance in advancing, the waste fuel oil increases mechanical wear.

The purpose of this utility model is at above-mentioned the deficiencies in the prior art part, and provide a kind of when driving engine stops to drive, the resistance of getting rid of engine drive mechanism, make full use of the force of inertia of car body in advancing, prolong operating range, thereby the saving fuel oil, the vehicle oil saving skid of minimizing mechanical wear.

The technical scheme that realizes above-mentioned purpose is: a kind of vehicle oil saving skid, and it has the main shaft that a front end has connecting flange, and the two ends of axle are equipped with bearing, assemble a shell through bearing, configuration one gear sliding sleeve on this shell; Extremely before be disposed with driven ratchet, driving ratchet and fastening ratchet by the back in the enclosure; Its driven ratchet is fixing anterior in the enclosure, and driving ratchet is assemblied in the middle part of main shaft through free-sliding spline, and the fastening ratchet is cooperated with shell by free-sliding spline; Sliding sleeve passes elongated hole on the shell fastening ratchet that is fixedly connected by screw; Be provided with annular groove on sliding sleeve, be provided with a pair of promotion bearing in the groove, this bearing is connected by a semicircle shift fork around sliding sleeve, and its shift fork cooperates with an electromagnetic valve through shifting fork bar; Between driving ratchet on the main shaft and anterior bearing, be equipped with a spring; Front end at main shaft is provided with jam nut.

The utility model volume is little, configuration is installed conveniently; Simple in structure, processing ease is reliable; Under normal circumstances use and to save fuel oil 15%-20%.

Fig. 1 is this fuel economizer for vehicle master cutaway view;

Fig. 2 is the left view of Fig. 1.

Below in conjunction with drawings and Examples the utility model is further described: provide as accompanying drawing, this device has a front end and has the main shaft 1 that is used for the axle drive shaft connecting flange, this two ends are equipped with bearing 2 and 7, through bearing 2 and 7 assemblings, one shell 6, configuration one gear sliding sleeve 3 on the shell 6.In shell 6, extremely before be disposed with driven ratchet 9, driving ratchet 10 and fastening ratchet 12 by the back.The inboard of its driven ratchet 9 and fastening ratchet 12 is provided with one side and is the double wedge that vertical surface simultaneously is the inclined-plane; The both sides of driving ratchet be respectively arranged with ratchet 9 and 12 on the active flank that coincide of protruding, recessed toothed surface.Driven ratchet and shell 6 solid weldings; Spline bearing fit on spline and the main shaft 1 is set in driving ratchet 10 axis holes; Fastening ratchet 12 is provided with the spline bearing fit in spline and the shell.Screw 4 passes on the shell 6 cooresponding elongated hole sliding sleeve 3 and fastening ratchet 12 is fixedly connected.Sliding sleeve 3 is provided with annular groove, and a pair of promotion bearing 5 is set in the groove, and bearing 5 is connected by a semicircle shift fork 13 around sliding sleeve 3, its shift fork band one shifting fork bar, and this shifting fork bar cooperates with electromagnetic valve 14.2 on driving ratchet and bearing are nested with a spring 11 on main shaft 1.Front end at main shaft 1 is provided with jam nut 8.

When this device uses; its front end is through flange and propeller shaft couplings; the rear end is connected on the flange of axle reduction device through screw retention; by sliding before and after the solenoid control fastening ratchet; the locking and the disconnection of control driving ratchet and driven ratchet, realization driving engine normally sliding with slight drag when microrunning slided, and makes vehicle when guaranteeing safety traffic; save fuel oil, reduce mechanical wear.
