Owners of classical carriages and also transforming carriages without rotary wheels at least once, but faced widespread defect when takes away a carriage at the movement aside - to the left or to the right. This problem can have several reasons. However you do not hurry to take a carriage to repare as you have a chance to repair it in house conditions.
Causes of defect of a carriage
There are three main reasons which provoke leaving of a baby carriage to the left. The first is concealed in the different pressure of tires. The second consists in asymmetrical geometry of a frame. It can be caused by external damage, temporary distortion or a production defect. The third reason is a curvature of an axis of a wheel.
Methods of elimination of the main reasons for defect of a carriage
For a start it is necessary to carry out diagnostics of all wheels of a baby carriage. Check pressure in tires and in case of need pump up a wheel. If all wheels are normal, pass to the following reason and try to correct geometry of the frame. Considering the fact that the distance of frames from two parties has to be identical, try to turn in a frame manually a little. For this purpose increase distance between wheels from that party in which conducts. In this case unclench the left side of a frame, and right, on the contrary, slightly squeeze. To avoid breakage of a carriage, it is necessary to apply a maximum of forces. After that carry out test drive.
To check the carriage course, take it in a straight line. If wheels continue to conduct to the left, try to repeat all procedure once again.
If it did not fix a problem, then pass to the third reason. Axes of wheels also play a major role in the equal course of a carriage. In the beginning perform thorough inspection, and then start repair. For this purpose turn a carriage so that back wheels were raised, and lobbies rested against a floor. Slightly step a leg on the left wheel and an axis near a wheel, a hand undertake an axis of a back wheel and breakthroughs begin to pull it up.
Try to pull without strong pressure not to break a wheel axis.
In such a way you will stretch width between a front and back wheel which because of the wrong addition or physical pressure can be reduced to 5 cm over time. Further turn a carriage back in a starting position and shake it with a side sideways. Test the movement of a carriage. If from the first to eliminate defect of an axis of wheels did not leave, do not despond, repeat this procedure anew. However pay attention that if your carriage has strongly broken geometry, then the frame cannot almost be leveled without the assistance of the expert and the special equipment. Therefore in the beginning estimate a carriage damage rate. If it is considerable, do not waste time and forces, address to service service.
