Description

RUNNING-OFF DEVICE FOR TRANSPORT

FACILITIES.

Technical field

The utility model relates to the field of transport engineering and can be used in vehicles to hold them when stopping on the rise.

The prior art.

A vehicle recoil device is known comprising a shoe with a bracket in which there is an opening with a bearing mounted in a fork on the wheel axle.

A fixing mechanism made in the form of an electromagnetic coil is installed on the vehicle body through a flange, the rod of which has the possibility of reciprocating movement and contact with the shoe (see RF patent for utility model N.> 26779, class B60T1 / 14, 2002 )

During operation of the device, when the vehicle is moving, the wheel chock is in the transport position, in which the shoes do not come in contact with the wheels. When the vehicle stops, for example, when lifting or, if necessary, stopping when the brake system fails, the shoe fixing mechanism electromagnet is turned on, as a result of which the rod is pulled into the coil and the shoe is released, which, under the influence of its own weight, rotates around the axis and is captured by the wheel, resulting in the vehicle brakes and stops.

The shoes can be mounted on all or several wheels of the vehicle.

The disadvantages of the known solutions are: - its bulkiness;

- the need for significant refinement of the vehicle, and

- requires considerable effort and time, since the initialization of the shoes is carried out manually.

- when moving along muddy dirt roads, shoes and mechanisms for their fixation are covered with mud and may not work at the right time.

The closest in technical essence to the proposed solution is a car anti-roll brake containing a housing with end caps in which a transmission shaft is installed that can be connected to the vehicle’s driving bodies (see RF patent ^ 2048326, class B60T7 / 00, 1995 .)

In the known device, the screws of the mirror-mounted kinematic screw-nut pairs are fixed on the shaft. The nuts have the ability to contact by means of concentrically symmetrically mounted springs with the corresponding side covers. Between the nuts in the housing there are two shafts with levers symmetrically attached to them by means of hinges, additionally, the levers are connected with the shafts by springs. The shafts are interconnected by gears, one of which has the ability to communicate with the control body.

When the machine stops on a slope under the influence of a control element, the gears rotate together with the shafts, together with which the levers rotate until they contact the corresponding nuts. The levers move the nuts axially towards the screws, overcoming the resistance of the springs. The movement of nuts continues until their screw contact screw thread cutting. The parking brake is set to working position.

When moving the machine downhill, the transmission shaft is rotated, and the nut is caught by the screw and the nut moves along the screw all the way into the side cover, which stops the transmission and stops the machine.

After moving the control to the neutral position, the nut moves to its original position by spring, the levers are brought out of contact with the nut.

When the machine starts moving the screw-nut pair, which participates in locking the transmission shaft, is moved by the screw until their screw cuts are disengaged and the nut returns to its original position under the action of the spring.

As a result of the analysis of the design of this device, it should be noted that the full control cycle is carried out by the driver from the cab of the vehicle, which is undoubtedly convenient.

However, this device is very difficult constructively, its installation on a vehicle is complicated and requires significant modifications to the transmission of the vehicle, and even with a small misalignment of the screw and nut, their screw threads will not come into contact with each other, which will lead to the failure of the device and exit building vehicle transmissions.

Disclosure of the proposed technical solution. The technical result of this utility model is the development of a recoil device of a vehicle simple structurally, easily integrated into the vehicle transmission, convenient and reliable in operation.

The specified technical result is ensured by the fact that in the recoil device of the vehicle, containing a latch designed to lock the vehicle’s transmission and associated with its moving mechanism that can be connected to an energy source is new, that the latch moving mechanism is mounted on a fixed vehicle suspension element in the area of the vehicle’s brake disc and is able to connect to a source energy of the vehicle or the manual control element, and the latch has the ability to interact with the locking elements, made bubbled on the brake disc.

Graphic Disclosure

The essence of the proposed utility model is illustrated by the description of the device and graphic materials on which a diagram of the recoil device of the vehicle is presented.

The best example of the implementation of the proposed technical solution.

The recoil device can be installed on one, several or all wheels of the vehicle and is made in the form of a vehicle mounted on a fixed suspension element of a vehicle, for example, a vehicle wheel support 1 of a locking mechanism 2.

This mechanism, having a housing 3 attached to a caliper, is connected to a vehicle energy source 4.

As the source of energy 4 for the operation of the mechanism, the energy accumulated in any of the vehicle systems: electric, pneumatic or hydraulic, can be used.

It is possible to implement the device using the muscular energy of the driver to move the latch. For this in an area accessible from the driver’s seat, a lever is installed, connected, for example, by means of a cable with a clamp or with a rod (if any), which is connected with the clamp.

The implementation of the claimed device will consider the example of using as a source of energy a regular battery 4 of the vehicle. In this case, an electromagnet 5, with which the battery 4 is connected, is used as a mechanism for moving the latch 2.

In the connection circuit there is a switch 6. The electromagnet, when connected to the battery, acts directly on the latch 2 or on the rod 7, which has the possibility of reciprocating movement.

The latch 2 is mounted to rotate relative to the housing 3, and in the presence of a rod is connected to the latter. Naturally, the latch 2, and if there is a rod in the design of the device, the rod 7 is made of magnetic material.

The latch 2 has the ability to interact with the locking elements made on the brake disc of the wheel.

The locking elements can be a recess "a", made (for example, by milling) on the generatrix of the brake disc 8 of the vehicle wheel.

The locking elements can be made in the form of holes at the end of the brake disc or in another way.

As practice has shown, the locking elements are most appropriate to perform in the form of slots of the form shown on graphic materials along the generatrix of the brake disc 8 evenly over its surface. The number of locking elements may be different and is not critical for the claimed utility model.

The brake disc 8 is connected to a rotating transmission element of the vehicle.

The mechanism for moving the latch, as mentioned above, can be structurally implemented in various ways, for example, similarly to its implementation in the patent for utility model 26779.

The known mechanism for moving the latch is made in the form of an electromagnetic coil installed in the housing of the mechanism, in which a rod (rod) 7 is placed, moving under the action of electromagnetic forces.

To improve the usability of the device in the area of the driver's seat, sound and / or light alarm elements can be installed, indicating the capture of the brake disc by the latch. Such elements are known and there is no need to describe them in detail.

When using the vehicle’s hydraulic or pneumatic systems as an energy source, the mechanism is in the form of a rod connected to a piston mounted in a hydraulic or pneumatic cylinder with the possibility of reciprocating movement due to the influence of a hydraulic or pneumatic environment.

In this case, a hydraulic or pneumatic distributor is used as an element for activating the locking mechanism of the latch.

The constructive implementation of this movement mechanism is not difficult for specialists. The proposed recoil device of the vehicle operates as follows.

We will consider the operation of the device using an example of using a standard vehicle electric battery as an energy source.

When the vehicle is moving, the latch 2 does not come into contact with the locking elements "a" of the brake disc 8.

When the vehicle stops on the rise, the locking mechanism is activated, that is, by means of a switch 6, the electromagnet 5 is connected to the battery 4, as a result of which, under the influence of electromagnetic forces, the lock moves, if there is a rod in the structure, the latter is drawn into the electromagnet and the lock 2 pivots.

In this case, the latch 2 enters one of the recesses "a" of the brake disc 8 and stops it, and, consequently, the entire transmission of the vehicle, which keeps the vehicle on the rise from rolling.

When the vehicle begins to move on the rise, a locking element, for example, a protrusion between the recesses of the friction disk 8, pushes the latch 2 out of the recess of the disk, as a result of which the latch 2 disengages from the disk 8 and the vehicle continues to move on the rise.

Industrial applicability.

It should be noted that this device provides reliable retention of the vehicle when it stops on the ramps without the use of standard brakes and easy pulling off.

The device is very simple structurally, inexpensively, easily mounted on a vehicle. A full cycle of device control is carried out from the vehicle cab.
