RU2592033C2 - Vehicle propulsor with increased cross-country capacity - Google Patents

Abstract

FIELD: transport.

SUBSTANCE: invention relates to high cross-country capacity and, in particular, to design of vehicle with devices providing improved contact of wheel with road in complex road conditions. Device comprises a wheel tire which is solid or filled with spongeous mass with radial holes placed along the circumference of wheel with bush-like seats, where studs are movably installed. Each stud is provided with a return spring, buffer and support, each of which interacts with one of cams or sequentially with all cams fixed on tubular shaft coupled with studs drive mechanism.

EFFECT: technical result is improved adhesion with road surface in complex road conditions without damaging the road surface.

Description

The invention relates to an off-road vehicle and, in particular, to the construction of wheels with devices providing increased wheel contact with the road in difficult road conditions.

Known vehicle propulsion (patent DE 2809147 A1 from 09/06/1979, B60C 11/16, B60B 15/12, B60C 11/14, B60C 27/04), comprising a wheel with a tire having radial holes in a circle in which are installed sockets of the sleeve type, in which the pushers are mounted movably with return springs, the pushers on the one hand interact through articulated couplings with lugs, where they are called grippers, and on the other hand, interact through a buffer with an eccentric mounted on a tubular shaft that is connected to the drive.

A disadvantage of the known propulsion system is the construction very difficult to manufacture, many parts in the working and non-working positions that are in contact with the ground, which requires constant monitoring and maintenance (cleaning from dirt, adjustment and repair). With slippery ground (ice, ice or liquid soil) slippage is very likely.

A massive tire is known (patent RU 2042531 C1, 08/27/1995). It is also known a wheel filled with a sponge mass (patent SU 3071 A 06/30/1927).

The aim of the invention is the creation of DTSPP, non-destructive pavement and included if necessary by the driver of the vehicle, and at the same time the creation of a simpler and more reliable design DTSPP. In addition, the proposed propulsion vehicle is intended for crushing (violation) of the ice crust (ice).

This goal is achieved by the fact that the mover of an all-terrain vehicle (DTSPP), including a wheel whose tire is solid or filled with a spongy mass, with radial holes around the circumference with radial sockets such as bushings in which spikes are installed with return springs interacting through a buffer, a support with an eccentric connected to the tubular shaft, which is connected to the drive mechanism of the studs, which, in turn, is connected to the control mechanism of the studs, characterized in that the mechanism the drive of the spikes is made in the form of a clutch, which contains a first driving part connected to the wheel shaft, a second stationary one connected to the body part and a carriage interacting with the first or second parts and axially movably connected by a splined connection to the tubular shaft, while the carriage connected to the control mechanism.

The control mechanism is made in the form of a pneumatic-hydraulic system.

Brief Description of the Drawings

In FIG. 1-3, a mover of an off-road vehicle is schematically shown, including a wheel consisting of a hub 1, a disk 2, a rim 3 and a tire 4, which is solid or filled with a spongy mass, with radial holes located around the circumference with sleeves such as bushings 5, of which the studs 6 are movably mounted, which are equipped with a return spring 7, a buffer 8 and a support 9 (in the form of a plate), which interacts with the eccentrics 10 mounted on a tubular shaft 11 connected to the stud drive mechanism, which, in turn, oedinen with the control mechanism.

The stud drive mechanism is made in the form of a clutch containing the first part 12 connected to the wheel shaft 13, the second stationary part 14 connected to the housing 15 and the carriage 16, interacting with the first 12 or second 14 parts of the clutch and mounted axially movably splines on the tubular shaft 11.

The control mechanism is made in the form of a pneumatic-hydraulic system 17.

Vehicle propulsion

When moving a vehicle with a road accident on the road in the absence of sliding, the spikes of 6 wheels should be removed and not in contact with the road surface (surface).

In this case, the carriage 16 connects the first drive portion 12 of the clutch to the tubular shaft 11, which rotates the eccentrics with a speed equal to the number of revolutions of the wheel. When wheel slippage occurs or when entering a road section where slippage is possible, the driver acts on the drive carriage 16 by the control mechanism, opening it with the first driving part 12 and closing it with the second part 14 stationary, while the tubular shaft 11 connected to the carriage 16 , brakes the eccentrics 10, and the tire 4 with spikes 6 continues to rotate relative to the stationary eccentrics 10, which squeeze the spikes 6 from the socket of the tire 4 outward by the amount provided during installation, thereby providing increased clutch wheel roadbed. Depending on the selected mode, the driver can leave the spikes 10 extended or they will undergo the action of eccentrics to crush the ice on the road.

Thanks to the use of the proposed mover of an off-road vehicle, it becomes possible to use the vehicle in off-road conditions, also on roads with a high-quality surface, without fear of damage.
