Abstract
The present invention relates to a kind of dynamic toe-in regulating instrument and method. The dynamic toe-in regulating instrument consists of bogie, drum, pull rod, sensor and horizontal pedestal, and features that two bogies on the horizontal pedestal are connected with sensors via pull rod and each of the bogies is shaft connected to two parallel drums. The dynamic toe-in regulating method features that after the vehicle to be regulated has its front wheel or rear wheel set on the instrument, the wheel has its toe-in regulated dynamically and locked after the side force component of the wheel to the instrument become zero. Compared with available technology, the present invention has the features of fast detection speed, high precision, dynamic compensation, wide application range, etc.
Description
Technical field
The present invention relates to a kind of dynamic front beam and adjust instrument and method of adjustment thereof, is that a kind of method of dynamic power sensing that adopts is adjusted coaxial front-wheel of automobile or real wheel toe angle, in order to the instrument that guarantees that its tire is minimum to the ground sideslip, wearing and tearing are minimum.
Background technology
Now, automobile has become an indispensable part in China's people's lives as a kind of vehicles.And whether the wearing and tearing of automotive wheel normally more and more receive the concern of car owner and government, because toeing-in is defective, cause tire premature wear and deformity wearing and tearing, it is very big that tire is scrapped the economic loss that causes in advance, sometimes the environmental pollution that also can causing blows out causes traffic hazard, Tyte Wear to cause also is very serious.Now, be the static wheel static toe-in angle of measuring at the revolution orientator that is used to adjust toeing-in on the market.Because not high its prenex error that causes of manufacturing accuracy of automotive wheel is very big, repeatability is bad, and simultaneously, owing to be static amount, the factor of many dynamic variations is not taken into account, causes prenex the adjustment less than optimum value, and the wearing and tearing of wheel can not be reduced to minimum.The present invention is at automotive wheel forward in the rolling process, measure the cross component force of tire by mechanism to ground, and to make cross component force by the relevant parts of adjusting automobile be zero, this moment the wheel lateral sliding be zero, the toe-in angle of wheel also reached optimum condition, thereby remedied the deficiencies in the prior art.
Summary of the invention
The object of the present invention is to provide a kind of dynamic front beam simple in structure, that measurement is accurate, repeatability is high to adjust instrument and method of adjustment thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this, it mainly is made up of dolly (1), cylinder (2), pull bar (3), sensor (4) and horizontal base (5), it is characterized in that: two dollies (1) are positioned on the horizontal base (5), two dollies (1) are connected with sensor (4) by pull bar (3), are connected with two parallel cylinders (2) on each dolly (1).
Described two dollies (1), wherein the inboard of a dolly (1) is affixed with horizontal base (5) by pull bar (3) and sensor (4).
Described sensor (4) is pull pressure sensor, linear movement pick-up or angular displacement sensor.
A kind of dynamic front beam is adjusted the instrument method of adjustment, it utilizes dynamic front beam adjustment instrument to carry out, it is characterized in that being adjusted vehicle front-wheel or trailing wheel places dynamic front beam to adjust on the instrument, adjust prenexly in wheel, and the cross component force that makes a wheel of being shunt adjust instrument to dynamic front beam is zero back locking.
The present invention compared with prior art its detection speed is fast: the toe-in that detects a car only needs several seconds; The precision height: can be accurate to 0.5mm, institute shunts in the sideslip amount of breakking away when detecting less than ± 0.5m/Km; Dynamic compensation is arranged: because the manufacture deviation of wheel tyre causes toe-in value that bigger variation is arranged, use the present invention to compensate, can suitably increase and decrease its toe-in value, and guarantee that its sideslip amount to ground is zero, reduce tire wear to greatest extent to it; Adapt to wide: the present invention is applicable to vehicle wheel distance any four-wheeled vehicle, truck, car, jeep and tractor within the specific limits.
