Description
Technical field
This utility model belongs to automobile technical field, and the front-wheel orientation relating to a kind of automobile shows
Showing device.
Background technology
Automobile is that before utilization orientation dish drives, crop rotation turns to, in order to alleviate steering-load,
Typically suitable speed reducing ratio is set between steering wheel to front-wheel, in order to provide more comfortable driving
Sailing space, power steering mostly installed into by automobile now, and this makes the manipulation of steering wheel
More laborsaving, that especially car its effect when resting state is more notable, traditional common side
It is very painstaking to handle during resting state sub-to jiggering, and dynamic steering wheel is the lightest and easy
Lift, but, the Labor-saving of steering simply allows driver more comfortable, owing to automobile is driven
The person of sailing can not see the actual rotational angle of vehicle front, without suitably instruction device is
Auxiliary, be not easy on the contrary to turn the most correct by angle, often just will unconsciously
Angle turns the biggest or the least, and this situation is especially when curb parking and reversing warehouse-in
It is particularly easy to occur, when unfamiliar new hand runs into these situations, often to attempt perhaps
The most just success, after in place, the angle of front-wheel still cannot be learnt, often in car
Must first pop one's head in before after son stops determining or outputing in advance and inspect, bring inconvenience to driver, and
And easily produce security incident.
