1. Introduction
is the distance between the track center line on the plane supporting the vehicle wheels (typically ground is) left track. If both ends of the axle when the wheel is double, double track is the distance between two center plane of the wheel.
Tread
car front track and the rear track of track points, a front track center plane between the front two wheels distance is a distance between the rear track wheels two rear center plane, both may be the same or different.
in general, the wider the track, the higher the driving comfort, but some China-made cars no power of direction, if it is too wide front track steering wheel will be very “heavy”, affecting driving comfort.
In addition, the track width of the car but also the total, weight of the total, lateral stability and safety impact.
2, wheelbase gap
before and after the track there will be differences caused by human design.

is greater than the theoretical benefits of the front track rear track is that: when the vehicle speed cornering outside front wheel maximum force which the front wheel the wider the distance Li Ju smaller play through the roll, so the track generally over the track after
can be greater than the front-wheel-gauge track, so to increase straight running stability of the car at high speed, for example, before and after the country tread 1495mm and 1520mm respectively Civic production. Swift wheelbase 1470mm and 1480mm respectively. the same as the longitudinal track 307 1699MM
wheelbase and track there is no fixed ratio flag, wheelbase big turning radius, bend performance is not good, but will increase interior space, comfort will be improved. Mazda 6 is a B-class wheelbase should be two meters seven, in order to pursue performance can be shorter wheelbase (2640 mm) cut, BMW car, too!
3 Characteristics
In general, the greater the track, the better for smooth manipulation, while the degree of styling and spacious compartment is also advantageous, better lateral stability. However, the wide track, the car’s total weight and total width generally increase, and prone to the problem of body side throw mud. If the track is too wide it will also affect vehicle safety, therefore, should be compatible with the track width of the body.
