The invention relates to the automotive industry, and is intended to improve the performance of electric vehicles (EM), mostly electric vehicles for urban services, through the use of mechanical spring recuperators energy.

Known EM for energy recovery when you stop EM and use this energy during further movement of EM are various devices.

Particularly recommended for GM flywheel batteries (equivalent Gulia N. In. The energy storage. - M.: Nauka, 1980; Gulia N. In., Bramblings S. A. a New concept of the electric car. 06.02.2000 .(e-mail:bychk-ao&msiu.ru)) have the following disadvantages: the necessity of evacuating the cavity of the location of the flywheel, the complexity in the connection zone of the flywheel shaft with transmission EM for violating seals in the joints, limited in time preservation of recovered energy in a rotating flywheel, mandatory placement of the plane of rotation in the horizontal plane due to the creation of gyroscopic the moment affecting the controllability of EM.

the brake pedal and the pedal unit speed, remote control and propulsion (power unit), which includes an electric motor with rechargeable batteries, mechanical gearbox, connecting axis motor drive for rotation of the differential to the leading axes EM and having at least one intermediate axle, where the energy recovery staying EM is carried out by means of electrochemical accumulators (Batteries), which are recharged by connected in the braking process of the motor operating in generator mode (prototype - the prospectus of JSC "AVTOVAZ, Lada 2131 Electro". Togliatti, 1999).

The disadvantages of the known devices include the following: - minor is recuperated energy, which is equal to approximately not more than 20% of the energy staying EM, which significantly reduces the overall mileage EM; - low efficiency of the Battery when used in the terms "peak" loads, for example, for the initial process to unseat GM as to process the moving motor connected to the mechanical transmission system EM, requires initially a sharp increase in current; - low pickup EM, for example, the lack of opportunity when moving EM fast acceleration and speed.

This object is achieved due to the fact that in the known construction of the electric vehicle, consisting of a body of the car, the chassis brake system having a brake pedal and a pedal with an inductive generator speed, control and propulsion, comprising an electric motor with rechargeable batteries that provide power to the motor and when working as a generator, the energy recovery staying electric, mechanical gearbox, connecting the axis of the motor driven differential for leading axes of the electric vehicle and having at least one intermediate axle, the axle of the electric motor and the first (or even) of the intermediate axis of the mechanical gearbox is made extra long, they installed the dowels or splines, two clutches and two bevel gears on a sliding fit, which are in contact with the bevel gears mounted on a fixed landing on the secondary axis located perpendicularly to the axis of the motor and connected with the axle mechanical recuperator clutch and sitting with them on the same axes of the bevel gears have the opportunity to contact for torque transmission, for example, using a ratchet device or clutch with synchronizer, and the couplings are connected by a lever and have three positions: neutral, connect the mechanical power recuperator its charge, i.e., for the recovery of up to 100 from the staying power of the electric vehicle, and the inclusion of mechanical power recuperator on the operating mode, i.e. at the beginning of the movement of the electric vehicle, and the control lever couplings and the item off ratchet mechanical recuperator energy for its operation, associated with the electromagnets, the unit automatically connect mechanical power recuperator, for movement of the electric vehicle is transverse rail in the area of the pedals electric, operated by an electromagnet with remote and containing two terminal electrical sensor applied consistently under the foot pedal of the electric vehicle.

Moreover, the mechanical power recuperator connected with additional mechanical axis of the reducer of the electric vehicle through the drive gear and with the axis of the motor and the intermediate axis mechanical gearbox through two cylindrical gears mounted on these axles on a sliding fit, with a third of qi is ICEM device mechanical power recuperator (MRA), for evaluation of the end position of the spring with rekorda-contact position sensor of the mechanical spring recuperator energy and associated with the device, showing the actual level of his boot.

The essence of the invention represented in the drawings, which shows: Fig.1 is a top view on EM, equipped with MRI; Fig.2 - drive EM from the electric motor to the differential with the installation of MRA angle 90oin the context of Fig.3 is a diagram of the device for switching the operation mode of MRA; Fig.4 - cross section a-a in Fig.2 (scheme monitor the actual state of the spring, MRE); Fig.5 is a view along arrow b of Fig.2 (scheme include MRA by an electromagnet), and Fig. 6 - drive EM with the connection MRA through the cylindrical gear; Fig.7 is a view, shown in Fig.2, which shows the drive EM with the connection MRA through the drive transmission of Fig.8 is a connection diagram of MRA to the pedals EM.

The electric vehicle 1 (Fig.1) consists of a body 2, the transmission to the wheels 3, a motor 4 with rechargeable batteries placed in any vacant plots of EM (not shown), transmission 5 connecting the axis of the motor 4 with 6 differential and half shafts 7 and 8, the mechanical power recuperator 9, pedal driven is adamcik speed 11, ensuring the inclusion of MRE on the fire with the moving of EM.

In Fig.2 shows the drive EM from the electric motor 4 to the differential 6 installing MRA 9 at right angles to the axis of the electric motor 4, which includes the transmission 12, where the first axis 13, connected to the shaft of the motor 14 via the torsion bar, and the second axis 15, which gear device for reducing the speed of the differential, have an extra long weekend ends, on which are installed on a sliding fit bevel gears 16 and 17 which are in contact, respectively, with gears 18 and 19 rigidly mounted on the axle 20, which is located perpendicular to the axis of the shaft 14. On the shafts 13 and 15 rear gears 16 and 17 are installed on the two dowels of the coupling 21 and 22 for coupling with these gears, for example, using a ratchet device or disk friction clutch.

The axle 20 has at the end of the connecting adapter, such as a splined connection or chetyrehrunny, which is provided to transfer torque from the shaft 20 to the axis of MRE 23 and Vice versa.

To set the operation mode EM with MRA serve couplings 21 and 22, the position of which is defined by the two electromagnet 24 and 25 (Fig.3), which upon rotation of the rocker arm 26 to move the clutch 21 and 22 to contact with sestet is disabled.

When charging MRA, i.e. the rotation of the shaft 23 with the drum 27 in the direction of the wave spring 28 (Fig.4) to its end position 29, the end of the spring presses on the rod 30, which, along with the control of General by the limit switches 31 and 32, shows the actual load of the spring due to built additional Rekord 33 associated directly with the sensor on the remote control driver (not shown). A jammed coiled spring 29 is carried out by the dog 34 in contact with the ratchet wheel 36 (Fig.5) fixed to the drum 27 (Fig.2). To start in the spring in condition 29 dog 34 is given by the electromagnet 35.

To connect MRA to the transmission 12 through the cylindrical gear instead of the bevel gears 16 and 17 (Fig.2) on the same axes on a sliding fit are cylindrical gears 37 and 38 (Fig.6), which contacts the third cylindrical gear 39, to the axis 40 which connects the axis 23 of MRA 9.

If necessary, install MRA 9 EM in any convenient place of its connection with the transmission 5 of EM is ensured through the use of drive shafts 41 (Fig.7), where the dashed line shows a possible position of MRA 9.

For automation control Analena spring-loaded transverse rolling pin 44, in fixed limit switches 45 and 46, which are the knobs work MRA, moved into the working position (shown dotted), namely under the appropriate pedal, is carried out by the electromagnet 47, the inclusion of which provides the driver by switching the toggle switch on the remote control (not shown).

Work EM (with MRA made in any of the options listed in Fig.2, 6 and 7), depending on the state of MRA: 1st case is when MRA pre-opened, the 2nd case is when MRA pre-opened and the 3rd case is when, by incorporating MRA, it must immediately disable is as follows.

the 1st case. The driver, sitting in the ER, includes power supply, while the toggle electromagnet 47 should be included and the end 46 to be under the foot pedal 43. Next, the driver pressing on the pedal 43, presses the end 46, which comprises sequentially: first, the electromagnet 24 (Fig. 3), which provides the moving ratchet clutch 21 and the connection of the shaft 14 of the electric motor 4 with the axis of MRE 23 (Fig.2), and then turns on the electromagnet 35 (Fig.5), providing for the withdrawal of the pawl 34 out of engagement with ratchet wheel 36, and MRA transmits rotation to the wheel axis EM, marking a movement axis of the sensor 30 moves down and presses his plate on the end 31, turning off the power supply to the electromagnets 47, 24 and 35. This leads to the fact that the rolling pin 44 (Fig.8) moves to the left position, providing the output of the sensor 46 from contact with the pedal 43, creating the possibility of operation of the electric motor EM in normal mode, i.e., by pressing a foot pedal 43 to the inductive generator speed of EM (not shown), the clutch 21 is disengaged, a spring-loaded dog 34 locks the ratchet wheel 36, and the end 45 is moved by the pedal 42.

During the next braking EM driver presses the pedal 43 and presses the foot pedal 42, pressing down on the end 45, which includes the electromagnet 25 (Fig. 3), providing movement of the coupling 22 and the intermediate connection axis 15 with the axis of MRE 23 (Fig.2), which leads to the twisting of the spring from position 28 to 29 (Fig.4) when the end of the spring presses through the rod 30 to end 32, which gives a command to turn off the electromagnet 25 and the electromagnet 47 (Fig. 3), which moves the roller 44 in the right position. At the same time the pressure on the pedal 42, if the braking due to MRE not ended until the end, provides braking in normal mode, i.e., due to a brake system of EM.

the 2nd case. The driver, sitting in the ER, includes power supply, not including the toggle electromagnet 47, which EM energy, MRA, according to the 1st occasion, when the need arises disable MRA and stop EM, pressed the pedal 43, which disables the end 46, which in turn removes power from the electromagnet 35, the retaining pawl 34 (Fig.5), which stoparic ratchet wheel 36 and MRA 9 is turned off, while pressing the brake pedal 42. This makes the charging MRA and braking, as noted for the case of 1.

To estimate the state of MRA on the dashboard of the driver has two indicator lights associated with the sensors 32 and 31, showing, respectively, the "Loaded" and "Free". Along with this there is established the scale of the actual load MRA associated with rekorda 33.
