Abstract

A driving motor with a shift fork mechanism for a hybrid electric vehicle relates to driving motor structures, and structurally comprises a casing, a stator, a rotor, a spindle, a bearing, a front end cover and a rear end cover, wherein the shift fork mechanism comprises shift forks and a cylinder. The driving motor is characterized in that the part of the rear end cover of the motor close to the outer circumference axially extends outwards to form a tubular body; the end part at the other end of the tubular body radially extends outwards to form a flange plate; a plurality of round holes formed on the flange plate correspond to a plurality of threaded blind holes distributed at the corresponding end of a diesel engine; clearance fit sleeves are in seat holes of the left shift fork and the right shift fork; the other end of a shift fork rod at the left end part of a fork shaft is hinged with a cylinder piston rod; sleeves at the lower parts of the U-shaped shift forks are fixed on the fork shaft; and the block of the cylinder is fixed on the threaded blind holes corresponding to a platform additionally arranged on the casing of the motor. The driving motor has the advantages that as the motor and the diesel engine are sleeved together, the precision of the shaft axis is guaranteed; and meanwhile, as the shift fork mechanism, the cylinder and the motor are integrally arranged, the space is saved, and installation errors are avoided.

Description

The drive motor of hybrid vehicle band shifting fork mechanism

Technical field:

The utility model relates to the drive motor structure, particularly the drive motor of hybrid vehicle band shift fork structure.

Background technology:

Hybrid vehicle drives power and changes diesel engine, motor coaxle driving into by traditional mono-diesel powered.Be that the diesel engine mouth is realized crankshaft drive by power-transfer clutch and electric machine main shaft, the electric machine main shaft other end is implemented coupler with the automobile drive axle transmission shaft and is connected, and realizes two-motor drive.The cylinder of diesel engine incomplete combustion causes denseer discharge amount of exhaust gas when auto idle speed or low speed, in this stage by motor as tripping force, diesel powered was just as propulsive effort after the speed for the treatment of rose to 20 kilometers/hour.That is to say idle low-speed stage, disengaging of clutch between diesel engine and the motor, this power-transfer clutch closure during normal speed, diesel powered is given the drive axle transmission shaft by the electric machine main shaft carry-over moment that stops takeoff output as the transition transmission.And the accumulators energy storage of also can generating electricity the electrical generator of diesel engine tail end at this moment, for the electricity consumption of idle low-speed stage machine operation, this process control is finished by integrated circuit.

Its mounting means generally is with bolt diesel engine base to be fixed on the car chassis, equally also be to be fixed on by the electric machine stand that support, casing, stator, rotor, main shaft, bearing are formed on the chassis with bolt, clutch driving case is fixed on diesel engine output axle head, and clutch driven disc spline housing running-fit is enclosed within on the castellated shaft of input shaft end of electric machine main shaft.And shifting fork mechanism is made up of mounting, shift fork, cylinder, it is tabular that shift fork is the Y font, the screens of fork plate U font front fork is in the vertical cooresponding circular groove of Moving plate of power-transfer clutch, the latter half of vertical plate of fork plate is enclosed within by middle part circular hole running-fit on the fulcrum pin cylindrical of mounting correspondence position setting, and vertically the terminal circular hole of plate is implemented to link by bearing pin with the cylinder piston boom end circular hole that is fixed on the mounting.

There are two defectives in this motor and shifting fork mechanism: the one, and motor leans on the fixed installation meeting on support and chassis to have coaxiality error owing to the setting accuracy error makes between electric machine main shaft and the diesel engine output shaft, influence transmission of torque, installation aligns operation simultaneously also influences work efficiency.The 2nd, shifting fork mechanism has a style of one's own to exist and takes up room and the setting accuracy problem.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned defective, and a kind of drive motor of hybrid vehicle band shifting fork mechanism is provided.

Scheme of the present utility model is: a tubular body axially outwards extends at the nearly excircle of back end cover for motor place, this end, tubular body other end flange that radially outward extends, several circular holes that are provided with on this flange are corresponding with several tappedes blind hole that the diesel engine corresponding end distributes; Tubular body lower half circle middle part two symmetrical sidewalls are provided with left and right sides shift fork seat, a declutch shift shaft running-fit is enclosed within the shift fork seat medium pore of the left and right sides, fit was fixed a shifting fork bar after tubular body was stretched out in the declutch shift shaft left part, shifting fork bar other end long slot bore running-fit is enclosed within the U-shaped forked standard of cylinder piston rod front end, implement the hinge joint of sliding by bearing pin, the level of U-shaped shift fork bottom is combined on the declutch shift shaft to the sleeve fixed cover, and shift fork U font front fork is in clutch plate circular groove screens relevant position in the tubular body; The cylinder seat of cylinder is bolted on the corresponding tapped blind hole of the platform of setting up on the motor case by four.

Advantage of the present utility model is: motor and diesel engine are implemented socket, guarantee the axial line accuracy rate, and shifting fork mechanism, cylinder and motor integration setting simultaneously saved the space and exempted installation error.

The specific embodiment:

Structure of the present utility model is made up of casing, stator, rotor, main shaft (1), bearing, front end cover, rear side housing (2), shifting fork mechanism comprises shift fork, cylinder, it is characterized in that: a tubular body axially outwards extends at back end cover for motor (2) nearly excircle place, this end, tubular body other end flange that radially outward extends, several circular holes that are provided with on this flange are corresponding with several tappedes blind hole that the diesel engine corresponding end distributes; Tubular body lower half circle middle part two symmetrical sidewalls are provided with left and right sides shift fork seat (7), a declutch shift shaft (6) running-fit is enclosed within left and right sides shift fork seat (7) medium pore, fit was fixed a shifting fork bar (5) after tubular body was stretched out in declutch shift shaft (6) left part, shifting fork bar (5) other end long slot bore running-fit is enclosed within the U-shaped forked standard of cylinder piston rod front end, implement the hinge joint of sliding by bearing pin, the level of U-shaped shift fork (3) bottom is combined on the declutch shift shaft (6) to the sleeve fixed cover, and shift fork U font front fork is in clutch plate circular groove screens relevant position in the tubular body; The cylinder seat of cylinder (4) is bolted on the corresponding tapped blind hole of the platform of setting up on the motor case by four.

Earlier clutch driven disc is linked on the motor rear end castellated shaft during installation, and with the shift fork screens, clutch driving case is fixed on the diesel engine mouth, then back end cover for motor (2) flange is aimed at the corresponding screw bolt of diesel engine, realize integrated location, the setting accuracy height, efficient also improves.Drive the shift fork beat by cylinder, shift fork can be swung in rectangular window.
