Motorized towing vehicle

Abstract

The invention is related to the class of small-scale tracked transportation vehicles, which can be used for towing a person and cargo using a sledge, for example. The motorized towing vehicle comprises a frame supporting a caterpillar drive, a platform supporting an engine with a transmission, a luggage space, an assembly for connecting to the object being towed object, a control device, and an object being towed. The caterpillar drive includes a caterpillar track, a metal subframe, a driven shaft and a driving shaft with pinions, and torsion-type wheel bogie. The control device consists of a steering wheel with handles and controls. The object being towed comprises a driver's workplace. The frame consists of a platform and a rigid framework enclosing the platform along the entire perimeter, including the luggage compartment with an additional luggage space above. The design of the frame and platform is asymmetrical relative to the track because of an extension of the platform in one direction. The subframe is in the form of metal side plates connected to the frame with brackets bent into an S-shape. The subframe plates accommodate a track tightening mechanism in the form of an eccentric and self-aligning bearings. An all-weather hood is used for protecting the engine and luggage space. The road performance of the motor towing vehicle has been improved.

Description

(1) The following schemes provide a better insight into the construction and features of the proposed motorized towing vehicle:

(2) FIG. 1—overall view of the motorized towing vehicle with a towed object;

(3) FIG. 2—frame (high and low);

(4) FIG. 3—propulsion unit (tracked and non-tracked);

(5) FIG. 4—transmission;

(6) FIG. 5—folding seat on the towed object;

(7) FIG. 6—a photo of the motorized towing vehicle covered with an all-weather hood.

(8) The proposed motorized towing vehicle comprises a frame 1 carrying a caterpillar drive 2, a platform 3, carrying the engine 4, a luggage space 5, an assembly 6 for connecting to the towed object, a control device 7, a towed object 8. The caterpillar drive features a track tightening mechanism in the form of an eccentric 9. The control device consists of a steering wheel 10 with handles and controls. The engine 4 and the luggage space 5 are covered with an all-weather hood 11. The towed object 8 contains the driver's workplace.

(9) The frame 1 consists of the platform 3 and a rigid frame 12, enclosing the platform along the entire perimeter, including the luggage space 5 with additional luggage compartment at the top 13. The frame 1, along with the platform 3, is asymmetrical relative to the track because of an extension of the platform in one direction, which allows placing the transmission chain drive 14 within the dimensions of the platform.

(10) The platform 3 carrying the engine 4 with the transmission 14 and the luggage space 5, is made from waterproof laminated plywood rigidly attached to the frame.

(11) The control device features the steering wheel 10 and controls. The wheel 10 is made from tubes in the form of a metal truss and is attached to the upper part of the frame using plates 15 with three points of attachment 16 and the wheel position limiter 17.

(12) The caterpillar drive 2 includes a track, a metal subframe 18, a driven shaft 19 and a driving shaft 20 with gears, torsion-type wheel bogies 21. The metal side plates of the subframe 22 are made with cut-out holes and connected to the frame by brackets bent into an S shape 23. Brackets of this shape allow you to place the subframe within the dimensions of the tracks. The subframe plates allow you to place on them the track tightening mechanisms in the form of an eccentric 9 and self-aligning bearings 24.

(13) The layout of the transmission elements is implemented via increasing the length of the intermediate shaft 25, mounted on the support brackets 26, 27, located far enough from each other to allow you to place the driven pulley of the variator 28, brake mechanism 29, and reverse gear on the shaft. The intermediate shaft 25 is also mounted on self-aligning bearings 24.

(14) The all-weather hood 11 protects the engine and the luggage space from snow, rain, and dirt.

(15) The towed object 8 is in the form of a sledge, equipped with a seat 30 made in the form of a tubular welded structure with a folding back. The back and seat are made of laminated waterproof plywood.

(16) The proposed motorcycle works as follows.

(17) The towed object 8 (e.g., a drag or light sledge) is connected to the motorized towing vehicle via a coupling device. Before driving, the driver sets the steering wheel 10 in one of the three attachment points 16 in accordance with his/her height. The engine 4 sends the torque 14 to the track through the transmission and the motorized towing vehicle moves forward or backward with the help of the reverse gear. The driver occupies the seat 30 of the towed object 8. The direction, in which the motorized towing vehicle moves, is changed by the driver via moving the steering wheel 10 to the right or left relative to the sledge, and the driving speed is adjusted using the engine controls 7 placed on the steering wheel handles 10.

(18) Specific examples may include the Baltmotors motorized towing vehicle, which has undergone factory tests and the pilot operation of the first batch.

(19) Thus, the proposed motorized towing vehicle allows its owners to benefit from having a compact small-sized, tracked motorized towing vehicle, which is convenient, safe, reliable to use, compact for transportation, and has an increased service life.
