Abstract
A kind of lorry turntable steel ball power assisting device.When semi-trailer automobile in motion, due to operating conditions such as acceleration, braking, turnings, semitrailer will generate the inertia force in various directions；On the other hand, it since the power of the vertical direction generated when semitrailer and traction seat connect is mainly born by the joint face between the saddle of traction seat and the lower surface of semitrailer, causes to wear.A kind of lorry turntable steel ball power assisting device, its group includes: traction turntable (1), towing pin (2) and hanging plate (3), the side of traction turntable offers steel ball placing groove (4), limited block (5) are welded in steel ball placing groove, limited block is welded at the center location of steel ball placing groove, the identical traction pin jack (6) of diameter is offered at the center location of traction turntable and limited block, the thickness for drawing turntable is identical as the depth of steel ball placing groove, and hanging plate is mounted on the top of traction turntable.The utility model is applied to lorry traction table.
Description
Technical field
The utility model relates to a kind of lorry turntable steel ball power assisting devices.
Background technique
The loading towing motorcar that cargo semitrailer is big as a kind of loading capacity, bearing capacity is strong has obtained more and more extensive
Ground application, and traction seat is installed on tractor as the important component of semi-trailer automobile by towing pin, towing pin is half
Trailer connect with tractor and bears the important component of tractive force, is connected with traction seat.Its act on be realize towing motorcar and
Connection between semitrailer is affected and is separated.And when semi-trailer automobile in motion, due to operating conditions such as acceleration, braking, turnings,
Semitrailer will generate the inertia force in various directions, especially when headstock is taken a sudden turn, rub between the saddle of existing traction seat
Coefficient is big, it is easy to headstock will be paid, on the other hand, the power of the vertical direction generated when being connect due to semitrailer with traction seat
It is mainly born by the joint face between the saddle of traction seat and the lower surface of semitrailer, joint face between the two directly connects
Touching, causes to wear, greatly shortens the service life of traction seat.
Summary of the invention
The purpose of the utility model is to provide a kind of lorry turntable steel ball power assisting devices.
Above-mentioned purpose is realized by following technical scheme:
A kind of lorry turntable steel ball power assisting device, group include: traction turntable, towing pin and hanging plate, and the traction turns
The side of disk offers steel ball placing groove, and limited block, the limited block welding are welded in the steel ball placing groove
At the center location of the steel ball placing groove, opened up at the center location of the traction turntable and the limited block
There is the identical traction pin jack of diameter, the thickness of the traction turntable is identical as the depth of steel ball placing groove, described
Hanging plate be mounted on the top of the traction turntable, and inserted with the towing pin on the hanging plate, by described
Towing pin connects the hanging plate with the traction turntable.
The lorry turntable steel ball power assisting device is placed with the identical steel of one group of diameter in the steel ball placing groove
Pearl, and steel ball described in one group places 95% or more of slot space full of the steel ball, the diameter of the steel ball is greater than described
Steel ball placing groove depth, and the top of steel ball described in one group is bonded with the bottom panel of the hanging plate.
The lorry turntable steel ball power assisting device, the same level of the two sides in the outer disk of the described traction turntable
On be welded with two nut A, two nuts B, the nut A and the spiral shell are welded in the two sides middle position of the hanging plate
Female B structure is identical.
The utility model beneficial effect achieved is:
1. the utility model structure is simple, the steel ball placing groove on traction turntable is put into several steel balls, is full of steel ball
95% or more of steel ball placing groove volume is to be able to make steel ball that can have enough spaces to roll in steel ball placing groove, so
Hanging plate is placed into the top of traction turntable afterwards, the bottom surface of hanging plate is bonded with the top of several steel balls, and traction turntable setting is existed
On the saddle of traction seat above tractor, and the saddle for drawing turntable and traction seat is fixed by towing pin, works as semi-mounted
In motion, due to operating conditions such as acceleration, braking, turnings, the top of one group of steel ball is arranged in hanging plate to vehicle, when the headstock of lorry is turning
Xiang Shi is put into steel ball, energy in the steel ball placing groove in traction turntable by the way that traction turntable is arranged between traction seat and hanging plate
It enough protects and causes to wear between the saddle on hanging plate and traction seat, increase the service life of traction seat, and can be good at
It turns round in the original speed of headstock, turns round flexibly, reduce the friction on tire and ground, increase the safety system of vehicle
Number.
2. the utility model traction turntable two sides be welded with nut A, be welded with nut B in the two sides of hanging plate, when
When connecting to traction turntable with hanging plate, it will be put into one group of steel ball in steel ball placing groove first, is then directed at nut A and nut B,
Bolt is screwed in nut A and nut B, making makes to draw by bolt turntable connects with hanging plate, when traction turntable is installed to traction
When on the saddle of seat, bolt is taken out from nut A and nut B, it is time saving and energy saving during installation.
