The vehicle tilter

 

(57) Abstract:

Usage: the invention relates to a lifting-transport equipment and can be used for maintenance of vehicles, if necessary, their rotation in order to obtain access to the bottom. Tilter use the minimum area and has great performance. For this purpose the base of the tilter has upper and lower curved guides and swivel platform relies on them by the upper rollers placed on the vertical platform bracket, and bottom. The lower rollers of the platform is connected to the rotation mechanism. Vertical platform bracket installed booster cushion can travel the length and breadth of the vehicle. 1 C.p. f-crystals, 3 ill.

The invention relates to a lifting-transport equipment and can be used for maintenance of vehicles, if necessary, their rotation in order to obtain access to the bottom.

Known tilters, based on the principle of rotation of the vehicle about a fixed transverse axis (longitudinal tilters) or fixed to the longitudinal axis (transverse is to all areas of the bottom of the car and require a large room height. Cross-tilters easier, but occupy a large area, so as to turn the vehicle on its outer edges. In addition, the casting-off in both cases requires considerable effort and capacity, as accompanied by a significant rise of the center of gravity of the vehicle.

Also known tilters rotary type [3] Their advantage is the low drive power, and the lack of high altitude vehicle entry and accordingly the length of the ramp.

The closest analogue is a device that contains a frame, a hinge mounted on it an arrow with the reference link, which is equipped with a side stand, with an emphasis on its upper end [4] the Design of this complex, cumbersome and requires a large area.

The technical result to be obtained from use of the invention is to reduce the number of structural elements, which eliminates the above disadvantages.

The technical result is ensured by the fact that the tilter vehicle containing the base, the turntable is available for all wheels of the vehicle and a vertical bracket with a support pillow for the last and the rotation mechanism is in a vertical, moreover, at least one of them is curved to reduce the load on the elements of the tilter and the optimal trajectories of the center of gravity of the vehicle, while on a turning platform for interacting with placed in the horizontal plane is fixed bottom support rollers, which are connected with the mechanism of rotation of the platform on a vertical bracket are the last of the upper support rollers for contacting placed in a vertical plane curvilinear guide and booster cushion mounted for movement along and across the vehicle. The base can be equipped with wheels, locking jacks and folding ramps.

Distinguishing features: the base has guides, one of which is located in a vertical plane, and the other horizontal. Rotary platform has an upper and lower support rollers upon which it is based respectively on the vertical and horizontal rails of the base. At least one of the rails, vertical, made of a curved shape, which reduces the efforts on the elements of ustroish, for example, in the form of a lead screw with a nut pivotally connected to the axes of the upper or lower support rollers, and it is advisable to combine it with the rollers moving along a linear track.

The base can be equipped with wheels that allow you to move the device in an unusable state on the floor, folding ramps for vehicle entry and jacks, which is set tilter in the working position.

To eliminate transverse displacement of the vehicle when tipping on vertical platform bracket adjustable booster cushion. It is a lever system with the reference area that can be allocated in the sides for the free passage of the car and pojeta to him before casting-off.

This design allows you to rotate the vehicle about its longitudinal axis within the area occupied by the tilter. The tilter has a high performance, because all preparatory operations after arrival of the vehicle to the platform occupied by not more than one minute. Tilter provides full access to the underside of the vehicle and its components from the bottom.

Next, we consider the Ana and straight vertical guide, although this scheme is less rational.

In Fig. 1 shows the design of the tilter of Fig. 2 scheme of rotation; Fig. 3 given an explanation on the choice of the geometric parameters of the guides.

The device consists of a base 1 with 2 vertical and 3 horizontal rails of the rotation mechanism and the turntable 4. The base is equipped with wheels 5, jacks 6 and folding ramps (not shown) for the vehicle. Swivel platform 4 with a vertical bracket 7 with the top 8 and bottom 9 of the rollers communicates respectively with 2 vertical and 3 horizontal rails. On the rotary platform has a platform 10 with clips for wheels (not shown) and mounting pad 11 to hold the vehicle when turning. The shifting mechanism is performed, for example, in the form of a lead screw 12, which is driven by a drive 13. Nut 14, which is located on the screw, through a detachable coupling 15 is connected to the axle of the roller 9.

The device operates as follows.

Tilter move on wheels 5 in the service area. For the folding ramps car enters the turntable 4 so that the wheel eorie through the nut 14 and a detachable coupling 15 move the lower support rollers 9. The upper support rollers 8 move along the upper guide rails 2, resulting in the platform rotates. For the reverse movement of the turntable rotation mechanism is activated in the opposite direction.

To ensure a sufficiently large angles of rotation of the platform is essential to the angle of inclination of the guide, located in the vertical plane, in its lower part, in the area where is the upper roller at the maximum angle of rotation of the platform. Jamming of the mechanism for happening, if you will condition

>+-/2, where the friction angle in the vertical guide;

the angle of rotation of the platform.

When this effort in the rollers and the screw will be the smaller, the greater the angle . Form vertical guide in the upper part is selected from design considerations to provide maximum compactness and the optimal trajectory of the center of gravity of the vehicle when handling.

The proposed design can be driven another type, for example, cable chain, using pneumatic or hydraulic drive.

SUBSTANCE: claimed method comprises placing of the vehicle on the bearing horizontal surface and applying the test load thereto. Tilting moment is created relative to the vehicle lengthwise axis unless the vehicle one side wheel breakaway from said bearing horizontal surface. Then, the force is applied to the vehicle sprung part perpendicular to vehicle lengthwise axis in the plane drawn through the geometrical gravity centre. Then, the sprung part bank angle is measured. In compliance with the first version, the vehicle crosswise static stability angle is defined. In compliance with the second version, the amount of tilting moment is defined and vehicle crosswise static stability angle is calculated.
