                     Small tracked electric all-terrain vehicle

This utility model relates to vehicles and is a compact all-season all-terrain tracked all-terrain vehicle on electric traction, which can be used in various industries, agriculture and utilities, tourism, healthcare and other sectors of the economy and social sphere.

The closest analogue (prototype) of the utility model is the Ziesel device of Mattro Mobility Revolution (Austria). Manufacturer Website: http: // http://www.derziesel.com. This device has the ideology and layout of an electric wheelchair for people with limited mobility and a similar control system. Instead of wheels, two ready-made caterpillar modules are used, manufactured by Camoplast (USA), which are mass-produced for use on ATVs as an additional off-road option. Each tracked module is additionally equipped with a separate electric motor, which transmits torque directly to the drive shaft of the tracked module. The speed and direction of movement of the device are controlled by the Joystick, which through the controller controls the direction and speed of rotation of each of the two electric motors. The engines are powered by lithium batteries, which, together with the control unit, are located under the driver / operator seat. The frame of the device is made of curved round pipes of various diameters. The tracked modules are mounted to the frame through a multi-link spring suspension and has one shock absorber and spring on each side.

Such an all-terrain vehicle is not suitable for driving on deep loose snow, crust, sand, loose and soft soils, swamps and thin ice due to the heavy weight of the all-terrain vehicle 270 kg. In addition, the high caterpillar module frame - 60 cm. Sets a high center of gravity of the entire structure, which reduces the stability of the device, because with a high center of gravity, the structure is prone to overturn when moving on inclined surfaces.

The technical result obtained in the implementation of the proposed utility model is to increase the cross-country ability of an all-terrain vehicle on loose snow, crust, sand, loose and soft soils, on marshy soil and thin ice, as well as to increase the all-terrain vehicle's stability when moving on sloping surfaces due to lowering the center of gravity of the entire structure and the reduction of specific pressure on the surface area.

In addition, reducing the total weight of the all-terrain vehicle to 180 kg versus 270 for the prototype by reducing the metal consumption of the structure as a whole, significantly simplifies loading and transportation of the all-terrain vehicle with the help of a trailer, an on-board vehicle, a pickup truck or a utility vehicle.

The technical result is ensured by the fact that in a small tracked electric all-terrain vehicle, including a support-bearing frame with a platform for fastening the payload, tracked modules, each of which is equipped with an electric motor, and a battery, tracked modules are equipped with shock-absorbing balancing rollers, electric motors mounted outside the tracked modules, and the drive shaft of each tracked module is connected to the motor shaft by means of a flexible transmission.

The utility model is illustrated by drawings, where in FIG. 1 shows a side view of an all-terrain vehicle; FIG. 2 shows a photograph of a prototype.

The proposed utility model is built on two tracked modules (1), each of which includes: driving (2) and driven (3) shafts, two shock-absorbing roller-balancers (4) and a track (5). Each track module is equipped with an electric motor (6), which is mounted on a subframe (7) and is located behind the track perimeter of rotation. The torque is transmitted from the motor shaft to the drive shaft of the caterpillar module through flexible transmission (8).

Caterpillar modules are rigidly connected to the supporting-bearing welded tubular frame (9), on which the driver / operator’s chair (10) and / or the platform for securing the payload are mounted. In addition, a safety arc (11) is installed on the support-bearing frame, which reduces the risk of injuries to the driver / operator in the event of an overturning of the all-terrain vehicle. The all-terrain vehicle controls are located on the steering wheel (12) of the driver / operator. The direction of movement and the speed of the all-terrain vehicle are controlled using two gas knobs on the steering wheel of the driver / operator, which determine the speed of rotation and the direction of rotation of each of the caterpillar modules. The battery pack (13) consists of two sections, each of which is located on a platform mounted on the frame of the corresponding track module, directly above it. The batteries through the controller (14) provide power to the electric motors. Due to the small height of the track module - 280 mm versus 600 mm for the prototype, and the location of electric motors outside the track module, the all-terrain vehicle has a low center of gravity. Due to the fact that the driver’s / operator’s chair is located above the tracked modules, and not between them, as in the prototype, it becomes possible to use wider tracks of 380 mm versus 280 mm in the prototype, while maintaining the overall width of the all-terrain vehicle as in the prototype. Wider tracks and reduced all-terrain vehicle weight due to reduced metal consumption minimize the specific pressure of the all-terrain vehicle on the surface area and, as a result, significantly improve its cross-country ability on various types of surfaces.

The utility model works as follows.

The driver turns the power switch to the ON position. And thereby the battery power is supplied to the control unit of the all-terrain vehicle. While in the chair, the driver uses the trigger type gas handles to control the all-terrain vehicle, which are located to the left and right of it. The left throttle stick controls the speed of rotation of the electric motor located on the frame of the left caterpillar module, and the right throttle stick controls the operation of the right electric motor. The direction of movement of the all-terrain vehicle is determined by the speed and direction of rotation of the electric motors of the caterpillar modules, using toggle switches located on the driver’s steering wheel to the right and left of it. In addition, on the steering wheel, on both sides of the driver, there are brake handles and rear-view mirrors that allow the driver to see obstacles when reversing. Cargo can be transported both on an all-terrain vehicle and in a towing device pivotally connected to the all-terrain vehicle. When the all-terrain vehicle moves in the dark, an LED headlight is located on the safety arc. The headlight toggle switch is located on the steering wheel. To turn off the all-terrain vehicle, you must stop it and turn the power toggle switch to the OFF position.
