Corners of installation of wheels - the general information, check and adjustment of convergence of forward wheels

General information

The geometry of a suspension bracket and steering drive of the car is defined by four base installations: disorder, corners longitudinal (выбег) and cross-section inclination of an axis of turn of a wheel and convergence. All parameters are expressed in angular sizes (convergence can also will be defined in millimeters). Convergence of forward wheels of the car belongs to number of parameters subject to adjustment only.

The corner on which the planes of wheels are rejected from a vertical is called as disorder. Disorder is called as positive when the upper edges of wheels are rejected from a vertical outside. Otherwise speak about negative disorder.

The corner on which the axis of turn of a wheel is rejected from a vertical in the disk plane is called as a corner of a longitudinal inclination of an axis of turn of a wheel. The corner is considered positive when the axis is inclined by the top end back.

The corner, between a vertical and the imagined line which has been carried out through support of a rack of a suspension bracket at a view of the car in front or behind is called as a corner of a cross-section inclination of an axis of turn of a wheel.

The size on which distances between lobbies and back edges of inside of rims of disks of wheels differ is called as convergence. At positive convergence back edges of disks are placed more widely, than lobbies, and on the contrary.

Check and adjustment of convergence of forward wheels

Exact measurement of convergence can be made only with use of the special precision equipment and demands from the performer of rather high qualification, and therefore it is necessary to leave his performance to specialists of car-care center. The check described below should be considered only as estimated.

 PERFORMANCE ORDER

1. Check of convergence of forward wheels is made by measurement of distances between lobbies and back internal edges of rims of rims and subtraction from the second result of the first. Necessary adjustment can be carried out for the account вворачивания / a reversing of tips of steering drafts for the purpose of change of length of the last.
2. Exact check of installation of convergence is made at net weight of the car, i.e. the salon and a luggage compartment should be unloaded, and the fuel tank is completely filled. Besides, previously the height of a road gleam (should be adjusted correctly see. Check of installation and adjustment of a road gleam).
3. Before starting to measurements make sure that wheels and tires correspond according to the tiporazmerny characteristics to requirements of Specifications. Check pressure of a rating of tires. Estimate degree of wear of a protector, size of palpation of wheels, a condition of stupichny bearings and components of a forward suspension bracket. Make necessary corrections.
4. Park the car on an equal horizontal platform, whenever possible with a firm covering. Bring forward wheels into rectilinear situation, then serially shake a back and a front for a usadka of suspension brackets. Release the parking brake and roll away the car back on 1 m, then forward for the purpose of removal of tension from suspension bracket components.
5. Measure distance between forward edges of internal rims of wheels, then between their back edges. Subtract from result of the second measurement result of the first and compare the received value to requirements of Specifications.
6. If need for carrying out adjustment takes place, prop up protivootkatny boots back wheels, then поддомкратьте a front of the car and establish it on props. Turn a steering wheel to the left against the stop, then count and write down quantity of naked rounds of a carving of a tip of the left steering draft. Now turn a steering wheel to the right against the stop and repeat check for the right draft. If on both drafts the same quantity of rounds of a carving is naked, from both parties of the car identical adjustments should be made. If on one of drafts of naked rounds it is more, such asymmetry should be eliminated in the course of adjustment.

On termination of adjustment the quantity of naked rounds of a carving on both drafts should appear strictly identical!

7. Clean a carving on the ends of steering drafts, having removed from rounds corrosion traces, in case of need moisten a carving with getting oil. Release external collars and unbend protective covers. Slightly grease an internal surface of covers in order to avoid a perekruchivaniye them at rotation of drafts.

8. Mark the provision of a bar of the first draft in relation to its tip, then holding a bar from a provorachivaniye a rozhkovy key, completely unscrew a lock-nut. Repeat procedure for the second draft.

9. Adjust as appropriate length of drafts (see the prevention provided above). Remember that reduction of length of drafts conducts to decrease in size to convergence/increase in size of a divergence.
10. Having achieved satisfactory result, strongly tighten lock-nuts of tips of steering drafts. Make sure of correctness of landing of spherical fingers in the nests and similarity of quantity of naked rounds of a carving (in case of need repeat adjustment). If length of drafts to leave unequal, inevitably there will be problems with centering of a steering wheel.
11. Having adjusted drafts for identical length, lower the car on the earth and repeat convergence check. In case of need repeat adjustment. Having achieved satisfactory result, strongly tighten lock-nuts of tips of steering drafts. Track reliability of landing of protective covers of tips, make sure that covers are not overwound, then fix them new collars.
