Abstract

Double-sided backstop refers to the automotive industry, in particular to vehicle braking means, and can be used to prevent unwanted movement of the car during loading and unloading operations using lifting and handling equipment. Double-sided anti-recoil stop contains two oppositely directed thrust shoes. The design of said thrust shoes prevents the wheel of the vehicle from rolling. The double-sided backstop contains movement limiters that prevent spontaneous removal and can be mounted on wheels of various diameters. 6 ill.

Description

The utility model relates to the automotive industry, in particular to means of braking vehicles and can be used to prevent unwanted movement of the vehicle. The wheel chock is used when carrying out loading and unloading operations using lifting and handling equipment that creates significant longitudinal forces when moving (shifting) goods in the car body, in particular, forks or wheel loaders.

The utility model is illustrated in the drawings:

FIG. 1 - double-sided backstop, general rear view;

FIG. 2 - double-sided backstop, general view from the front;

FIG. 3 - double-sided stop, front view;

FIG. 4 - double-sided backstop stop, side view;

FIG. 5 - double-sided backstop stop, top view;

FIG. 6 - double-sided backstop stop, rear view.

The double-sided backstop stop (Fig. 1) contains two oppositely directed thrust shoes (1, 2) mounted on a lockable sliding guide rod (3). Each of the persistent shoes (Fig. 2) contains an elongated base (4), a working surface (5) located at an angle of at least 40 degrees. to the elongated base (4), the stop edge (6), the free face (7) and is equipped with a vertical lateral displacement limiter (8) and a handle (9) for carrying and installing the stop. The stop edge can be performed as a continuation of the free face. Locking the sliding guide rod (3) is carried out by the pivot (10). The necessary range of movement of the elements of the sliding guide rod and the integral structure is provided by a restrictive bolt (11).

Known and used during loading and unloading using lifting and transport equipment a wedge for a vehicle wheel containing a rough base, a working surface with a tongue and a free face equipped with a reflector. On the free face, a recess was made to accommodate the reflector and a protective visor, which, having an undercut, is used as a handle for carrying the wedge, (see application for utility model RU 92014392, IPC (1995) B60T 3/00, 1995); also an anti-recoil stop, containing a base in which windows with bent edges are made, a concave working surface with a tongue that smoothly passes at an angle into the free face that serves as a handle, side faces with stamping and internal stiffeners (see patent RU 68439, IPC ( 2006) B60T 3/00, 2007). The closest in the set of essential features is an anti-recoil stop containing a base made with at least one window with bent edges, a working surface with a tongue turning into a free face, a handle, side faces with stampings, internal stiffeners (see patent RU 87397, IPC (2006.01) B60T 3/00, 2009).

The disadvantage of this emphasis is that when a considerable longitudinal force is applied to the car blocked by such a stop, the wheel of the latter rolls over the emphasis, as a result of which the braking of the car with the stop stops and the car can continue to move arbitrarily, including after the cessation of longitudinal force. The specified emphasis has a braking effect in one direction of the longitudinal axis of the car and, in the case of variable multidirectional external forces, to lock the car it is necessary to use two such stops simultaneously.

This utility model is aimed at achieving a technical result, which consists in maintaining the braking effect in the event of significant forces being applied to the vehicle in both directions along the longitudinal axis of the vehicle.

The specified technical result is achieved through the use in the design of two oppositely directed thrust shoes (1, 2) mounted on a lockable sliding guide rod (3), equipped with a working surface located at an angle of at least 40 degrees. to the elongated base (4), the stop edge (6).

When a longitudinal force is applied to a locked vehicle, the latter moves in the direction of the stop shoe, the car wheel rolls onto the elongated base (4) of the shoe until it contacts the stop edge (6). Further, since the force required to roll the wheel through the thrust shoe exceeds the force required to shift the stop, the stop moves. In this case, the car wheel remains within the limits created by the stop, and the stopping effect of the stop remains.

This useful model allows to realize the impossibility of rolling the wheel of a car through a thrust shoe at longitudinal loads exceeding the rolling resistance values created by the known wheel chocks.

Double-sided backstop can be made on standard equipment from known materials using known technologies.
